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 first and second brake pads and configured for pressing the first and second brake pads 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). The first plate (9) is rotatably supported by a brake bolt bracket (16) coupled to a braking bolt (13), and the second plate (10) is operably connected to a caliper housing bolt (14) connected with a caliper housing (33) such that the caliper housing (33) and the braking bolt (14) are configured to press the first and second brake pads against opposing surfaces of a brake disc when the braking member (12) executes the braking motion.

A brake device includes a brake caliper with a first frictional surface and a first actuation surface, a pressing part of the brake device being linearly guided along a first straight line on the brake caliper. The pressing part has a second frictional surface and a second actuation surface, a region being provided between the first frictional surface and the second frictional surface for arranging a brake element. The brake device has a rotatable spreading element which interacts with the first actuation surface and the second actuation surface. During a rotation of the spreading element, the rotation occurring in order to actuate the brake device, a first spreading element surface is in direct contact with a first rolling surface and rolls substantially on the first rolling surface, and the first rolling surface corresponds to the first actuation surface or the second actuation surface.

An electromagnetic braking device includes a brake disk, a fixed disk, an armature, a biasing member for biasing the armature, and a stator for attracting the armature. In a stator magnetic circuit member, a first yoke, a permanent magnet, and a second yoke are arranged in this order from one end to the other end of a U shape. In a rotatable state or a rotation braking state, even when the coil energization is OFF, the rotatable state or the rotation braking state is maintained. When a current of a predetermined magnitude flows through the coil in a first direction in the rotatable state, the state shifts to the rotation braking state, and when a current of a predetermined magnitude flows through the coil in a second direction in the rotation braking state, the state shifts to the rotatable state.
