The tighter the wheel tolerance, the closer the speed between the wheels. Systems that require tight wheel tolerances need the wheels to be operating at close to the same speed. The sensors found in an AC system are only there because of the need to keep the wheels operating at very close to the same speed.Keep in mind that propulsion systems essentially link (electrically or mechanically) a single power supply to a group of wheels. A diesel hydraulic system requires that all wheels are operating at essentially the same speed as all of the wheels are ultimately driven from the same gear. Allowable wheel speed differences (and hence diameter) are then limited by the tolerance stack up of the components in the drive train. Electrical propulsion systems are essentially the same only the drive train from the power source to the wheel consists of fewer components: cabling and the traction motors. The characteristics of the motors then become the determining factor. |
