Download or read book Hydraulic Valves for Motor Vehicle Brake Systems Test Procedure written by Hydraulic Brake Components Standards Committee and published by . This book was released on 2002 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The SAE Recommended Practice specifies the test procedure to assure valve assemblies which are satisfactory for vehicle usage, and it is applicable to new valve assemblies for commercial production. It covers such valves where they are employed in passenger car and light truck brake systems utilizing motor vehicle hydraulic brake fluids. This procedure and requirements (SAE J1137) was developed for brake fluids conforming to SAE J1703 and FMVSS 116 (DOT 3); however, it may be utilized for valves which use DOT 4 or DOT 5 brake fluid. These procedure specifications were developed for base brake operation and do not consider the effects of ABS (anti-lock brake systems) or traction control systems which may have a significant effect on the valve. Careful analysis of the particular type ABS and/or traction control (if included in the system) should be made and additional tests are required which are not included in this document. Provisions for ABS and traction control will be incorporated in a future revision or covered in a separate document. The minimum performance requirements are specified in SAE J1137.

Download or read book Low-duty Inertia Dynamometer Hydraulic Brake Wear Test Procedures for Vehicles Above 4536 Kg (10 000 Lb) of GVWR written by Truck and Bus Hydraulic Brake Committee and published by . This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Recommended Practice is derived from OEM and tier-1 laboratory tests and applies to two-axle multipurpose passenger vehicles, or trucks with a GVWR above 4536 kg (10 000 pounds) equipped with hydraulic disc or drum service brakes. Before conducting testing for a specific brake sizes or under specific test conditions, review, agree upon, and document with the test requestor any deviations from the test procedure. Also, the applicable criteria for the final test results and wear rates deemed as significantly different require definition, assessment, and proper documentation; especially as this will determine whether or not Method B testing is needed.This Recommended Practice does not evaluate or quantify other brake system characteristics such as performance, noise, judder, ABS performance, or braking under extreme temperatures or speeds. Minimum performance requirements are not part of this recommended practice. Consistency and margin of pass/fail of the minimum requirements related to wear rates and wear behavior can be assessed as part of the project in coordination with the test requestor.NOTE: This Recommended Practice uses the unit conversion and rounding techniques from the NIST Special Publication 811. This to ensure the use of standard conversion factors and to determine the appropriate number of significant digits to ensure the Rounding Error (RE) of the converted unit is smaller than or similar to the RE of the original English or Imperial unit. Certain vehicle applications (like flat-bed recovery vehicles) have driving patterns which are considered light-duty with (a) friction material temperatures remaining under 232.0 °C (450 °F) 2.03 to 2.54 mm (0.08 to 0.1 inch) below the braking surface for at least 90% of the time, and (b) brake applications which require 2690 kPa (390 lbf/in2) or less of hydraulic pressure. This Recommended Practice provides two inertia-dynamometer test procedures, which are repeatable and cost-effective to assess, screen, benchmark, troubleshoot, or fingerprint a given foundation brake regarding low-duty brake wear. The first procedure (or Method A) is a wear versus temperature test from 93.0 to 427.0 °C (200 to 800 °F) to determine if there are potential wear rate issues under low temperature conditions and a low-duty driving cycle. If deemed required after the initial wear versus temperature test (Method A), or upon direct customer request, the second procedure (or Method B) provides an extensive wear test at a constant temperature of 79.0 °C (175 °F) to determine the wear rates and behavior of the friction couple. Data from this Recommended Practice may be combined with other brake system and vehicle characteristics for a comprehensive product characterization program.Since other wear test procedures cover a different (higher) range of operating temperatures, kinetic energies, and levels, the accelerated wear rate behavior of certain friction materials under low-duty regimes is not properly determined or estimated using test conditions which can affect the transfer layer behavior. The wear test method implemented in this Recommended Practice was derived from prior field testing and correlation investigation. Hence, careful attention was given to not alter the sequence and test conditions which have demonstrated correspondence to the vehicle behavior.The SAE Truck and Bus Hydraulic Brake Committee considers laboratory test procedures useful in supporting harmonization to improve the overall performance, durability, and safety of motor vehicle braking systems using relevant and cost-effective protocols.

Download or read book FMVSS 105 Inertia Brake Dynamometer Test Procedure for Vehicles Above 4 540 Kg GVWR written by Truck and Bus Hydraulic Brake Committee and published by . This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Recommended Practice is derived from the FMVSS 105 vehicle test and applies to two-axle multipurpose passenger vehicles, trucks and buses with a GVWR above 4 540 kg (10 000 lbs) equipped with hydraulic service brakes. There are two main test sequences: Development Test Sequence for generic test conditions when not all information is available or when an assessment of brake output at different inputs are required, and FMVSS Test Sequence when vehicle parameters for brake pressure as a function of brake pedal input force and vehicle-specific loading and brake distribution are available. The test sequences are derived from the Federal Motor Vehicle Safety Standard 105 (and 121 for optional sections) as single-ended inertia-dynamometer test procedures when using the appropriate brake hardware and test parameters. This recommended practice provides Original Equipment Manufacturers (OEMs), brake and component manufacturers, as well as aftermarket suppliers, results related to brake output, friction material effectiveness, and corner performance in a laboratory-controlled test environment.The test sequences include different dynamic conditions (braking speeds, temperature, and braking history as outlined in the FMVSS 105); inertia loads equivalent to the vehicle's LLVW and GVWR; fully operational, partial failure, and failed system conditions. All applicable sections of the FMVSS 105 are included. Optional sections include: parking brake output, water recovery, TP-121D dynamometer retardation, and 32 km/h (20 mph) stops to simulate Federal Motor Carrier Safety (FMCS) requirements.This Recommended Practice does not evaluate or quantify other brake system characteristics such as wear, noise, judder, ABS performance, or braking under extreme temperatures or speeds. Minimum performance requirements are not part of this recommended practice. Consistency and margin of pass/fail of the minimum requirements related to stopping distance or equivalent deceleration levels of the FMVSS 105 vehicle test can be assessed as part of the project in coordination with the test requestor when using the appropriate vehicle information and vehicle dynamics modeling. Nevertheless, this procedure and its results do not replace the vehicle-level test to demonstrate compliance to FMVSS (105 for hydraulic brake systems or 121 for air-over-hydraulic brake systems), or other mandatory regulations (like ECE R13 or equivalents). Vehicle and braking systems development is fast-paced, and involves a global supplier base. This Recommended Practice provides an inertia-dynamometer test procedure that is repeatable and cost-effective. It evaluates the performance of the brake corner and its components (including friction material) by following the test procedure and sequence as indicated in the Federal Motor Vehicle Safety Standard (FMVSS) 105. Data from this Recommended Practice may be combined with other brake system and vehicle characteristics to predict vehicle performance.Since the first release of the FMVSS 105, there have been numerous inertia-dynamometer test protocols developed and used by the industry with different approaches and levels of detail. The SAE Truck and Bus Hydraulic Brake Committee considers laboratory test procedures useful in supporting harmonization to improve the overall performance and safety of motor vehicle braking systems.

This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Subject document is specifically intended for service brakes and service brakes when used for parking and/or emergency brakes (only) that are commonly used for automotive-type, ground-wheeled vehicles exceeding 4536 kg (10000 pounds) gross vehicle weight rating (GVWR). Subject specification provides the off-vehicle procedures, methods, and processes used to objectively determine suitability of tactical and combat ground-wheeled vehicle brake systems and selected secondary-item brake components (aka, aftermarket or spare parts), including brake "block" for commercial applications only, specifically identified within subject document. Subject specification is primarily based on known industry and military test standards utilizing brake inertia dynamometers. Targeted vehicles and components include, but may not be limited to, the following: aCivilian, commercial, military, and militarized-commercial ground-wheeled vehicles such cargo trucks, vocational vehicles, truck tractors, trailers, and specialized support and engineering equipment under the generic heading of ground vehicle "dry" brake systems (GVDBS). bHydraulic, air, and mechanical "dry" disc brake and drum brake systems, when used as service brakes, including service brakes (only), when used as emergency and/or parking brakes. cHydraulic, air, and mechanical "dry" disc brake pad assemblies and rotor assemblies. dHydraulic, air, and mechanical "dry" drum brake shoe assemblies and drum assemblies. eHydraulic, air, and mechanical brake "block" when intended for use on a. through d. above, except for those vehicles, pad assemblies, and shoe assemblies specifically procured for military use and/or tested under ATPD-2354. It must be noted that the U.S. Government's Military Services buys only assemblies, and doesn't normally use "brake block" and relined brake shoes/pads; therefore, testing using separate brake "block" was specifically excluded from ATPD-2354 by the original authors. This revision includes some editorial changes and updates to reflect current and applicable test procedures. This revision also includes a provision regarding braking systems fitted on vehicles with regenerative braking.

Download or read book Structural Testing of Passenger Car and Truck Disc Brakes written by Hydraulic Brake Components Standards Committee and published by . This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This SAE Recommended Practices specifies a procedure for determining structural strength and fatigue life of disc-brake caliper assemblies which are satisfactory for vehicle usage. It is applicable to new caliper assemblies which are employed in passenger car and truck brake systems utilizing hydraulic brake fluids. Brake design and vehicle performance requirements are not included. Specification limits are left to the discretion of the responsible manufacturer.This procedure was developed for base brake operation and does not consider some unusual effects of ABS (Anti-Lock-Brake System) or Traction Control systems which may have a significant effect on the caliper. Careful analysis of the particular type ABS and/or Traction Control should be made and additional tests may be required which are not included in this document. This Recommended Practice is being Stabilized because it represents caliper testing practices of the 1998 era and has not been materially revised since that time (just correction of typographical errors). The SAE Hydraulic Standards Committee does not plan to update this recommended practice, and instead has formed a Task Force that is currently working on SAE J2995 Strength and Durability Testing for Automotive Hydraulic Brake Components to be based upon current technologies and to consider vehicle duty cycles. SAE J1713 should be stabilized since it may still be used as a reference.
