Measurement of Vehicle and Suspension Parameters for Directional Control Studies

2018-01-02
CURRENT
J1574/1_201801
The parameters measured according to this SAE Recommended Practice will generally be used in simulating directional control performance in the linear range. (The “linear range” is the steady-state lateral acceleration below which steering wheel angle can generally be considered to be linearly related to lateral acceleration.) But they may be used for certain other simulations (such as primary ride motions), vehicle and suspension characterization and comparison, suspension development and optimization, and processing of road test data. This document is intended to apply to passenger cars, light trucks, and on-highway recreational and commercial vehicles, both non-articulated and articulated. Measurement techniques are intended to apply to these vehicles, with alterations primarily in the scale of facilities required.

The following list consists of hose data provided as of December 2017, and is for convenience in determining acceptability of nonmetallic flexible hose assemblies intended for usage under 46 CFR 56.60-25. Where the maximum allowable working pressure (MAWP) or type of fitting is not specified, use the manufacturer's recommended MAWP or type of fitting. This list has been compiled by SAE Staff from information provided by the manufacturers whose product listings appear in this document. Manufacturers wishing to list their products in this document shall: a. Successfully test their hose to the requirements of SAE J1942, Table 1. b. Submit a letter of certification to the SAE J1942 test requirements for each specific type of hose tested (see sample table on page 4) along with the test results. All sizes should be included in the same letter which must also include all of the information necessary to make a SAE J1942-1 listing. c.

Seven Conductor Cable for ABS Power - Truck and Bus

2017-12-20
CURRENT
J2394_201712
This SAE standard establishes the minimum construction and performance requirements for seven conductor 1/8-2/10-4/12 cable for use on trucks, trailers and converter dollies. Where appropriate, the standard refers to two types of cables, (Type F and S, described later in the standard), due to the variation in the performance demands of cables used in flexing and stationary applications. While the document’s title refers to ABS Power to differentiate the document from the SAE J1067 standard that it supersedes, the scope applies to both the primary green cable for powering ABS and lighting and the yellow auxiliary cable of the same construction.

Combined Cornering and Braking Test for Truck and Bus Tires

2017-11-29
CURRENT
J2675_201711
This SAE Recommended Practice describes a test method for determination of heavy truck (Class VI, VII, and VIII) tire force and moment properties under combined cornering and braking conditions. The properties are acquired as functions of slip angle, normal force, and slip ratio. Slip angle and normal force are changed incrementally using a sequence specified in this document. At each increment, the slip ratio is continually changed by application of a braking torque ramp. The data are suitable for use in vehicle dynamics modeling, comparative evaluations for research and development purposes, and manufacturing quality control. This document is intended to be a general guideline for testing on an ideal machine, and modifications to the protocols recommended within are expected depending on the requirements of each customer. Due care is necessary when modifying protocols to ensure that the integrity of the data is maintained.

Spherical and Flanged Sleeve (Compression) Tube Fittings

2017-11-29
CURRENT
J246_201711
This SAE Standard covers complete general and dimensional specifications for tube fittings of the spherical and flanged sleeve compression types for use in the piping of air brake systems on automotive vehicles. The spherical sleeve compression type Figures 1A to 5 and Tables 1 to 3 is intended for use with annealed copper alloy tubing per SAE J1149, Type 1. The flanged sleeve compression type Figures 6A to 11 and Tables 4 to 6 is intended for use with nylon tubing per SAE J844. It is not intended to restrict or preclude other designs of a tube fitting for use with SAE J844, air brake tubing. Performance requirements for SAE J844 are covered in SAE J1131. See SAE J1131 for the Performance Requirements of Reusable (Push to Connect) Fittings Intended for Use in Automotive Air Brake Systems.

CURRENT
J747_201711
This SAE Standard applies to hydraulic directional control valves as applied to self-propelled work machines referenced in SAE J1116. It describes a laboratory test procedure for evaluating: Flow versus pressure drop Leakage rate Operating effort Metering characteristics versus spool travel, pilot pressure, or electrical current Relief valve characteristics The document applies to single and multiple section hydraulic directional control valves. This document illustrates axial, manually operated valves although the test procedure is applicable to other input forms such as rotary actuation, electric current, hydraulic or pneumatic pressure. Performance characteristics such as metering hysteresis or dynamic response may have a significant effect on some of these tests.

Rating of Winches

2017-11-03
CURRENT
J706_201711
This SAE Standard applies only to new winches which are primarily designed for intermittent pulls and lifts and whose configuration and condition are the same as when they were shipped by the manufacturer. They are not intended to be used in any manner for the movement of personnel. They may be driven by any power source recommended by the manufacturer and will be capable of being powered in either direction. They will be equipped with an automatic safety brake system to control a load when lowering under power and positively hold a load when power is not being delivered to the winch. A hydraulic flow control valve or similar device may be used in the brake system to control a load when lowering under power. A clutch to release the drum for “free-spooling” may be provided and will be designed not to disengage itself under load. A drag brake may be provided to control “free-spooling,” but will not be relied on to control or hold a load.
