Abstract
A hydraulic braking assembly (14) for a vehicle comprising an electric servomotor (15), a master cylinder (16), a hydraulic fluid tank (17) mounted on the master cylinder, a hydraulic fluid level sensor (25) situated inside the fluid tank and monitoring the hydraulic fluid level inside the tank. The fluid level sensor is connected from the tank to the computer of the electric servomotor by a cable (26).
Claims11
A hydraulic braking assembly (14) comprising an electric servomotor (15) including an electric motor (22) and a computer (19), the computer being connected to a central control member by a first cable (24) and being used to actuate the electric motor when a brake pedal is actuated by a driver, a master cylinder (16) connected to the servomotor by a support piston (23) actuated by the motor of the servomotor, a hydraulic fluid tank (17) mounted on the master cylinder, said tank communicating with a chamber of the master cylinder to feed the master cylinder with hydraulic fluid, a hydraulic fluid level sensor (25) situated in a wall of the fluid tank to monitor the hydraulic fluid level inside the tank, characterized in that the fluid level sensor is connected from the tank to the computer of the electric servomotor by an electrical connector connected directly to the computer (19).
A hydraulic braking assembly (14) comprising an electric servomotor (15) including an electric motor (22) and a computer (19), the computer being connected to a central control member by a first cable (24) and being used to actuate the electric motor when a brake pedal is actuated by a driver, a master cylinder (16) connected to the servomotor by a support piston (23) actuated by the motor of the servomotor, a hydraulic fluid tank (17) mounted on the master cylinder, said tank communicating with a chamber of the master cylinder to feed the master cylinder with hydraulic fluid, a hydraulic fluid level sensor (25) situated in a wall of the fluid tank to monitor the hydraulic fluid level inside the tank, characterized in that the fluid level sensor is connected from the tank to the computer of the electric servomotor by a connection means (26), and wherein the computer of the servomotor has circuits for transmitting the signal from the sensor to the central control member.
