Heavy Truck and Bus Retarder Downhill Performance Mapping Procedure

2000-05-01

CURRENT

J1489_200005

The procedure covers the estimation of the total retardation capability available to a specific vehicle from: a Natural retardation (rolling resistance, aerodynamic drag, etc). b Engine drag c Engine, integral automatic transmission, driveline or trailer-axle retarders It assumes that foundation brakes are not used for maintaining speed on long mountain descents. Retardation is rated in terms of the maximum grades on which stable control speeds can be maintained for each gear over the range of highway speeds appropriate to that gear. For each gear, the calculation procedure determines maximum grades for at least four values of control speed ranging from the vehicle velocity corresponding to full load governed engine rpm, to the vehicle velocity corresponding to the engine rpm at minimum (idle) speed. In addition, the calculation procedure provides information on the total retarding power available for each gear.

[In the report of the SAE Motor Truck Rating Committee on Ability Ratings published in the January 1940 issue of the SAE Journal, it was recommended that pounds per certified net brake horsepower delivered to the clutch or its equivalent be used as the index of the potential ability of a motor truck or combination. This report defined the term "certified net brake horsepower" in detail and recommended that certain data be provided to support the certification. The accompanying forms provide a method for the presentation of the data specified.]

CURRENT

J688_199702

The procedure has been developed to provide a practical method for the prediction of truck performance using accepted data. It Is designed to help anyone concerned with the problem of truck selection. By following directions, it is possible to determine the necessary information for intelligent truck selection without being concerned with the origin or derivation of the complex factors involved. With readily available specification of a truck, information provided in the tables, and minimum of calculation, it is possible to predict: (a) The performance obtainable from a truck of given characteristics under given operating conditions. (b) The characteristics required in a truck to meet different performance requirements under given operating conditions. This report comprises a procedure form and 10 tables of data.

This SAE Recommended Practice establishes a single bolt pattern for the No. 1 clutch housing (see Figure 1) and the No. 2 clutch housing (see Figure 2). These four bolt patterns are designated to give commonality of mounting brackets in existing frame rails. The 420 mm (16.5 in) span, pad face to pad face, allows the ease of installation in existing frame rail widths. This is also the minimum spacing which will accommodate commonly used clutches.
