Brake device for trailer, has brake control unit arranged to receive brake signal, and to generate brake current whose value is proportional to value of load measuring signal

摘要

The device has an acceleration sensor (11) for generating a load test signal whose value is proportional to the loading of a trailer. A hydraulic brake assembly includes an electrically driven hydraulic pump (100) arranged for supplying pressurized hydraulic fluid to hydraulic brakes (14). A brake control unit (8) is arranged to receive a brake signal, and to generate a brake current whose value is proportional to the value of a load measuring signal, where the pump pressure is essentially proportional to the value of the brake power.
