摘要： The invention relates to an electro-mechanical brake with an actuator (5) for pressing at least one brake pad (3, 4) against a rotating friction surface. The actuator (5) comprises an electric motor (7) and a first transmission for converting a rotary motion of the electric motor (7) into a translational motion of the at least one brake pad (3, 4) for activating or releasing the electromechanical brake. Furthermore, the actuator (5) comprises a second transmission for converting a rotary motion of the same electric motor (7) into a further translational motion of the at least one brake pad (3, 4) to compensate for a wear of the at least one brake pad (3, 4), the first transmission and the second transmission being coupled so that the translational motion of the at least one brake pad (3, 4) caused by the first transmission and the further translational motion of the at least one brake pad (3, 4) caused by the second transmission add up to a resulting translation of the at least one brake pad (3, 4).

摘要： The present application relates to a friction brake system (1) for a vehicle. The friction brake system (1) comprises a braking member (12) connectable to at least one brake pad and configured for pressing the brake pad against a friction surface. The system (1) further comprises a transmission unit (2) configured for converting a rotary motion generated by an electric motor (30) into a braking motion of the braking member (12). The transmission unit (2) comprises a ball-in-ramp assembly (3) having a first plate (9) with at least one groove (23), a second plate (10) with at least one groove (22) facing the groove (23) of the first plate (9), and at least one ball (11) arranged between the first plate (9) and the second plate (10). The ball (11) is retained by the groove (23) of the first plate (9) and the groove (22) of the second plate (10). Further, the ball-in-ramp (3) assembly is configured to convert a rotary motion of the first plate (9) into a translational motion of the second plate (10) with respect to the first plate (9). The first plate (9) is configured to be rotated by the electric motor (30). Further, at least one of the first plate (9) and the second plate (10) is mechanically coupled with the braking member (12) such that a rotation of the first plate (9) causes the braking motion of the braking member (12). A depth of the groove (23, 24) of at least one of the first plate (9) and the second plate (10) increases between a first portion (24) and a second portion (25) of the groove (23, 24) in a non-linear manner such that a path defined by the groove (23, 24) is steeper in the first portion (24) than in the second portion (25).

摘要： The present invention relates to a brake system for a vehicle. The proposed brake system (1) comprises an actuation unit for actuating wheel brakes of the vehicle in a normal operating mode of the brake system (1). Further, the system (1) comprises a brake cylinder (2) for pressurizing the wheel brakes of the vehicle in an emergency operating mode of the brake system (1). The brake cylinder (2) comprises a brake cylinder housing (4) and a push rod (3) being displaceable within the brake cylinder housing (4) by operation of a brake pedal (5). The brake cylinder (2) further comprises a piston (14) movably arranged within the brake cylinder housing (4). The piston (14) has a first surface and a second surface opposite the first surface. A hydraulic chamber (11) is formed within the brake cylinder housing (4) between the first surface of the piston (14) and an inner surface of the brake cylinder housing (4). The hydraulic chamber (11) is configured for being selectively fluidly connected with the wheel brakes. The brake cylinder (2) further comprises an elastic simulator element (13) arranged between the second surface of the piston (14) and the push rod (3) for pedal feel simulation. The brake cylinder (2) further comprises a locking element (22) configured to selectively mechanically couple the push rod (3) with the piston (14) to provide a rigid connection between the push rod (3) and the piston (14) during the emergency operating mode.
