Low Floor Bus Powertrain Suspension

The powertrain suspension package which includes the engine, transmission, and both drive and steerable axles, in conjunction with the steering system, has a very definite role in determination of vehicle ride characteristics. The position of the engine and transmission in relationship to the drive axle and the effect on the handling capability of the vehicle had to be evaluated, along with the full axle suspension system, because of the drastic change in componentry and configuration in the low-floor transit buses.

Correlation between wheel geometry and ride characteristics has been proven mathematically, with test results and also by representative statistics provided by various vehicle operators.
