Disclosed herein a friction brake system comprises a braking member connectable to at least one brake pad and configured for pressing the brake pad against a friction surface and a transmission unit configured for converting a rotary motion generated by an actuator into a braking motion of the brake pad wherein the transmission unit comprises a ball-in-ramp assembly having a first plate with at least one groove, a second plate with at least one groove facing the groove of the first plate, and at least one ball arranged between the first plate and the second plate wherein the ball is retained by the groove of the first plate and the groove of the second plate, wherein the ball-in-ramp assembly is configured to convert a rotary motion of the first plate into a translational motion of the second plate relative to the first plate.

Friction brake system for a vehicle

Brake system () for a vehicle is provided, comprising a first hydraulic circuit () including a first wheel brake (), a second hydraulic circuit () including a second wheel brake (), a first hydraulic pressure supplier () including an actuator for pressurizing the first hydraulic circuit () in a normal operating mode, a second hydraulic pressure supplier () including an actuator for pressurizing the second hydraulic circuit () in the normal operating mode, a cut-off valve () hydraulically connecting the first and second hydraulic circuits (), a first control unit () for controlling the cut-off valve () and activating the first hydraulic pressure supplier () and the second hydraulic pressure supplier () depending on a brake request, and a second control unit () for controlling the cut-off valve () and activating the first hydraulic pressure supplier () and the second hydraulic pressure supplier () depending on a brake request.

Brake system

The present invention relates to a brake system comprising a brake pedal; a master cylinder including a first master chamber, a second master chamber, a first master piston, and a second master piston; a first hydraulic circuit; a second hydraulic circuit; a hydraulic pressure supplier including an actuator for pressurizing the first hydraulic circuit and the second hydraulic circuit depending on an operation of the brake pedal in a normal operating mode of the brake system; and an elastic pedal feel element arranged in the first master chamber to be in contact with the first master piston and the second master piston for generating a pedal force when the brake pedal is operated while the second master piston is locked in the normal operating mode.

Brake system including a master cylinder with an elastic pedal feel element

The invention relates to an electro-mechanical brake with an actuator () for pressing at least one brake pad () against a rotating friction surface. The actuator () comprises an electric motor () and a first transmission for converting a rotary motion of the electric motor () into a translational motion of the at least one brake pad () for activating or releasing the electromechanical brake. Furthermore, the actuator () comprises a second transmission for converting a rotary motion of the same electric motor () into a further translational motion of the at least one brake pad () to compensate for a wear of the at least one brake pad (), the first transmission and the second transmission being coupled so that the translational motion of the at least one brake pad () caused by the first transmission and the further translational motion of the at least one brake pad () caused by the second transmission add up to a resulting translation of the at least one brake pad ().

Electro-mechanical brake

The present invention relates to a master cylinder arrangement for a brake system, comprising a tandem master cylinder including a master cylinder housing, a first master piston movably arranged in the master cylinder housing, a second master piston movably arranged in the master cylinder housing, a balancing piston movably arranged in the second master piston, and an elastic pedal feel element. The invention further relates to a hydraulic system for a brake system as well as a brake system.

Master cylinder arrangement for a brake system

A brake system comprises a reservoir; a brake pedal; a master cylinder including a first master chamber, a second master chamber, a first master piston, and a second master piston; a first hydraulic circuit including at least one first hydraulic wheel brake; a second hydraulic circuit including at least one second hydraulic wheel brake; and a hydraulic pressure supplier including an actuator for pressurizing the first hydraulic circuit and the second hydraulic circuit depending on an operation of the brake pedal in a normal operating mode. The master cylinder further comprises a locking chamber and an elastic pedal feel element arranged in the first master chamber to be in contact with the first master piston and the second master piston for generating a pedal force when the brake pedal is operated while the second master piston is locked in the normal operating mode.
