  • Publication number: 20210231182
    Abstract: A disc brake lining is assembled depending on the rotation direction and includes a backing plate to carry a friction material, having diametrically opposed sides configured to be free from friction material. The backing plate is formed asymmetrically with respect to a central axis, and has a bearing on the inlet side relative to a preferred direction of rotation and provided radially inwardly in relation to a central wheel rotational axis, radially offset below a brake piston axis, as a holder with a hole for receiving a retaining pin, defining a fixedly positioned friction lining fixed bearing. A guide is on an allocated outlet-side bearing of the backing plate, radially outwardly in relation to the central wheel rotational axis, radially offset above a brake piston axis. The guide is an open-edged mouth opening with a receiving pocket receiving a guide pin, and defines a fixedly allocated friction lining floating bearing.

  • Patent number: 9920751
    Abstract: A hydraulic axial piston machine includes a drive shaft, a swashplate pivotable about a pivot axis to change inclination relative to a drive shaft axis, and an actuating piston approximately parallel to the drive shaft axis. The actuating piston has a first end which engages and adjusts the swashplate and a second end which bounds an actuating chamber. Fluid flows to the actuating chamber to pivot the swashplate one direction and is forced out of the actuating chamber when the swashplate pivots the other direction. A return element on the actuating piston incorporates a position of the actuating piston and thus the inclination of the swashplate into a control valve. The return element is positioned such that its longitudinal axis and an actuating piston longitudinal axis span a plane that differs from a plane perpendicular to the pivot axis.

  • Patent number: 9429153
    Abstract: A hydraulic dual axial piston machine includes a first driving unit and a second driving unit arranged one behind the other in the direction of the axis of a drive shaft and oriented opposite each other. The first and second driving units each have a respective swashplate and single actuating piston. The first and second actuating pistons exert load on a pivot cradle in a functionally identical manner to increase or decrease a pivot angle of the respective swashplate. The first and second actuating pistons are spaced apart from a central plane of the swashplates which extends through the axis of the drive shaft such that dimensions of a housing in the direction of the pivot axes of the swashplates are minimally influenced.
