Abstract
A braking arrangement for a vehicle includes a source of compressed air, a drive axle for the vehicle, a brake associated with the drive axle and connected to the source of compressed air by an air line, an operator controlled valve in the air line between the source of compressed air and the brake, a proportioning valve in the air line between the operator controlled valve and the brake. A compressor is driven by the drive axle or a drive shaft of the vehicle and has an outlet connected to a control port of the proportioning valve.
Claims18
A braking arrangement for a vehicle, comprising:
- a source of compressed air;
- a drive axle for the vehicle;
- a brake associated with the drive axle and connected to the source of compressed air by an air line;
- an operator controlled valve in the air line between the source of compressed air and the brake;
- a proportioning valve in the air line between the operator controlled valve and the brake;
- a compressor driven by the drive axle and having an outlet connected to a control port of the proportioning valve;
- a compressor driven by the drive axle and having an outlet connected to a control port of the proportioning valve;
- an antilock brake system (ABS) associated with the brake;
- a controller, and
- means for determining whether the ABS is operating properly and adapted to send a signal to the controller, the controller being configured to start operation of the compressor upon receipt of the signal that the ABS is not operating properly.
