Abstract: A wheel module for a vehicle, in particular for an electric motorcycle or electric scooter, includes a wheel axle and a wheel. The wheel having a wheel rim and said wheel rim being rotatably mounted on the wheel axle; and including a brake device for the wheel. The brake device having a brake pad and a brake disc for co-operating with the brake pad, said brake disc being axially movable in order to brake the wheel.

Abstract: A brake device for a vehicle comprising at least one wheel, in particular for an electric motorcycle or electric scooter, said device comprising a housing for positioning on a wheel axle of the vehicle. The vehicle has a brake disc for introducing braking power into a wheel rim of the wheel and transfer apparatus for transferring the braking power to the brake disc. The transfer apparatus is held in the housing and is operatively connected to the brake disc, said brake disc being formed integrally with the housing.

Abstract: A brake unit for a vehicle is disclosed, including a housing, a hydraulic unit, a braking element unit, wherein the braking element unit forms or supports a braking partner in a braking device for the vehicle. The housing, the hydraulic unit and/or the braking element unit define a main axis, wherein the hydraulic unit moves the braking element unit in an axial direction relative to the housing, in order to generate a braking force, and having a guide unit. The guide unit guides the braking element unit in the radial direction during the axial movement, wherein the guide unit has a master guide and an auxiliary guide, wherein the master guide and the auxiliary guide are arranged eccentrically.

Abstract: A coupling arrangement for a hydraulic device, in particular for a brake hose of a hydraulic brake of a vehicle. The coupling arrangement includes first and second coupling components, and the first and second coupling components can be transferred from an uncoupled state into a coupled state. The first coupling component has a hydraulic chamber which is prefilled with a first hydraulic liquid, and the second coupling component has a hydraulic cylinder which is prefilled with a second hydraulic liquid. The hydraulic chamber and the hydraulic cylinder are fluidically connected to one another in the coupled, a first flow opening is incorporated in the hydraulic chamber, and the first coupling component has a first sealing device which closes the first flow opening in a flow-tight manner in the uncoupled state and frees it in the coupled state.

Abstract: A fluid pressure operated actuating cylinder (11) for mounting in an aperture (13) in a wall (14) of a vehicle, the cylinder comprising a body (12) having first abutment tabs (17)(18) with a first locating surface (17a)(21a) facing in a first direction and second deflectable abutment lugs (17) and has a second locating surface (19a) facing in a second direction generally opposite to the first direction, the first and second locating surfaces (17a)(21a) being arranged to contact respective first and second oppositely directed surfaces (14a)(14b) of the wall 14 after insertion of the cylinder (11) through the aperture 13 with resulting deflection of the second abutment lugs (19) to locate the cylinder in the aperture.
