A ball screw drive comprises a spindle that includes a torque input portion and a body portion having a ball-screw drive inner raceway, wherein the body portion and torque input portion are met by a support bearing portion of the spindle that includes a support-bearing inner raceway grooved into a surface of the spindle, an outer ring including a support-bearing outer raceway and forming a channel with the support-bearing inner raceway of the spindle, and one or more support-bearing rolling elements arranged in the channel to contact the support-bearing inner raceway grooved into the surface the spindle.

The present disclosure relates to a brake actuator unit and to an electromechanical brake. The brake actuator unit has a spindle, which is driven in rotation by an electric motor, and a brake piston in the form of a spindle nut, which surrounds the spindle and is configured to press against a brake lining.

A drum brake apparatus for a vehicle may include: a cylinder device configured to apply a braking force to a shoe; a clip part extended from the cylinder device toward the shoe, and elastically contacting the shoe; a cylinder coupling part coupling the clip part to the cylinder device; and a shoe assembling part fastening the clip part to the shoe.

An electromechanical brake assist system driven by an electric motor cooperating with a master cylinder and having, along the axis of actuation, a helper piston in the shape of an axial sleeve solidly connected with a guide bracket and having a threaded surface. A nut, fixed in translation but free to rotate, has interior threads that complement those of the helper piston, which it receives, and exterior teeth that cooperate with the drive motor. A plunger piston carries a drive base so it can be pushed by the piston. Its other extremity is connected to the control rod, formed from a body and a head. The body has a crimping area and the head has a sleeve with an extremity that can be crimped along the crimping area.

An apparatus for generating non-electric control signals for a brake system, which has a first supply source, including: at least one interface configured to be connected to a pressure accumulator; and at least one interface to output the control signals; in which the apparatus is configured to be supplied via a second supply source. Also described are a related module and an electronic brake system

A motion conversion mechanism includes a shaft having an external thread and a cylinder having an internal thread that is screwed with the external thread. The motion conversion mechanism converts rotating motion of one of the shaft and the cylinder into linear motion of the other of the shaft and the cylinder. The cylinder is provided with two internal thread portions, each having the internal thread, such that a threadless portion is interposed between the two internal thread portions in an axial direction.

A module for providing control signals for a brake system of a vehicle which has a supply source, including: at least one interface to be connected to a compressed-air source; at least one interface to transmit the control signals to at least one processing unit for the purposes of generating brake pressures; wherein the module is configured to be provided with a supply by a further supply source. Also described are a related redundancy system, an electronically controlled brake system, and a method.
