Abstract: A ball nut assembly comprises a spindle having a longitudinal axis, a ball nut, and bearing elements supporting the ball nut on the spindle. First, second, third, and fourth ball nut deflectors are between the ball nut and the spindle. First, second, and third planes extend parallel to the axis. The first and fourth ball nut deflectors are in the first plane, the second ball nut deflector is in the second plane, the third ball nut deflector is in the third plane. Furthermore, the second and third ball nut deflectors are on opposite sides of the first plane. A first acute angle is between the first and second planes and a second acute angle is between the first and third planes.

Abstract: 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).

Abstract: A land vehicle with a disk brake, in particular a utility vehicle with a disk brake, has an axle with a first and a second flange surface for flanging a brake carrier of the disk brake. A first through-opening opens into the first flange surface and a second through-opening opens into the second flange surface. The first through-opening in a first region has a smaller clearance width than in a second region. The first region is located closer to the first flange surface than the second region.

Abstract: A brake system and method of adjusting a brake. The method may include the steps of providing a mechanically operated brake including friction material, providing a rotor, providing an adjuster for adjusting a running clearance between the friction material and the rotor, providing a sensor system for determining a likelihood of a braking event, and upon a determination of a change in the likelihood of a braking event operating the adjuster to adjust the running clearance of the brake.

Abstract: A readjusting device is provided for compensating wear of a brake pad or multiple brake pads and/or a brake disc of a pneumatically actuatable disc brake for a vehicle. The readjusting device has a mechanical actuator, and the mechanical actuator converts a rotational movement of a brake lever into a rotational movement of a shaft. The shaft rotates at least one threaded spindle which acts on one of the brake pads. The readjusting device can carry out an advancing movement and a return movement of the threaded spindle, and the advancing movement and the return movement of the threaded spindle can be terminated by switching one or more couplings.

Abstract: A metering device for controlling an oil delivery rate for a wet-running clutch. The wet-running clutch has at least one pair of interacting friction surfaces and an actuation unit for actuating the wet-running clutch. The actuation unit has an axially supported support disk and an axially displaceable thrust disk, wherein the thrust disk and the support disk are rotatable relative to one another. The metering device has a first component which is connected fixedly with respect to a housing, and a second component which is connected to the thrust disk in a rotationally conjoint and axially relatively displaceable manner.
