Abstract

System for reducing the brake wear of heavy vehicles, in particular for public transportation or for garbage collection, the vehicle comprising a pneumatic braking system for the actuation of the brakes, the wear reducing system being characterized in comprising limiting means, suitable to be activated, for limiting the air pressure within the pneumatic braking system.

Claims

1. A system for reducing the brakes wear of heavy vehicles, in particular for public transportation or for garbage collection, the vehicle comprising a pneumatic braking system for the actuation of the brakes, the wear reducing system being characterized in comprising limiting means, suitable to be activated, for limiting the air pressure within the pneumatic braking system.

2. The system according to claim 1, wherein said limiting means are suitable to be manually activated/deactivated.

3. The system according to claim 1, further comprising first control means for automatically activating said limiting means when a vehicle speed falls under a first predefined threshold.

4. The system according to claim 2, further comprising second control means for automatically deactivating said limiting means when a vehicle speed exceeds a second predefined threshold.

5. The system according to claim 1, wherein the pressure of the compressed air is limited at 3.5 bar when the system is active.

6. A heavy vehicle, especially for public transportation or for garbage collection comprising a pneumatic braking system for the actuation of the brakes characterized in that it comprises a system for reducing the brakes wear according to claim 1.

7. The vehicle according to claim 6, wherein said pneumatic braking system for the actuation of the brakes comprises separate circuits for controlling the actuation of brakes of the front wheels and for the actuation of the brakes of the rear wheels.
