An actuator comprises a housing () which contains a screw mechanism () and a motor () which is drivably connected to the screw mechanism (), said screw mechanism providing a linear movement in response to a rotational movement of the motor, and comprising a screw () and a nut () one of which is supported rotatably with respect to the housing (). The linearly displaceable member of the screw mechanism is drivingly connected to a pump mechanism for providing a flow of medium.

Actuator having a central support and brake calliper comprising such actuator

A screw actuator which has a housing, a motor, an actuating member and a screw mechanism which provides a linear movement of the actuating member with respect to the housing in response to a rotational movement of the motor. The screw mechanism has a screw and a nut engaging each other by rolling elements, one of the screw or the nut is rotatbly supported with respect to the housing, and a reduction gear means. The nut is fixed with repect to the housing, and the screw is rotatably supported with respect to the housing by mean of rolling elements.

Screw actuator, and brake caliper comprising such actuator

An actuator ( ) comprises a housing ( ) with a motor ( ) and a screw mechanism ( ), said screw mechanism comprising nut ( ) and a screw ( ) one of which is rotatably supported with respect to the housing by means of a screw mechanism support ( ) allowing relative rotations of the screw and the nut with respect to the longitudinal screw mechanism axis ( ), and an actuating member ( ) connected to the screw mechanism by means of an actuating member connection ( ), such that on relative rotation of the nut and screw the actuating member is displaced with respect to the housing. The screw mechanism support and the actuating member connection allow rotations having at least one axis transverse with respect to the longitudinal screw mechanism axis, so as to compensate traverse loading and bending moments.

Actuator with misalignment compensation

A screw actuator comprises a nut and a screw each comprising helical grooves, said nut and screw engaging each other by rollers or balls which are in contact with said grooves, a lubricant being provided for the grooves and rollers or balls. Integrated in the actuator is a module, which is connected to at least the helical grooves of the nut and/or screw for replenishing the lubricant for the grooves and rollers or balls of the actuator.

Screw actuator with lubricant dosing, and brake calliper

A screw actuator comprises a screw ( ) and a nut ( ) which are each provided with at least a helical groove ( ), and a series of rollers or balls ( ) which are in rolling contact with the grooves ( ). A sleeve ( ) is provided which surrounds the nut ( ) at least partly. The sleeve ( ) may carry a seal ( ) which acts between the nut ( ) and screw ( ); e.g. a wiper seal. The seal ( ) may be fixedly connected to the nut ( ), and frictionally engage the screw ( ).

Screw actuator comprising a multi-purpose sleeve, and brake calliper

An actuator ( ) comprises a housing ( ) which contains a screw mechanism ( ) and a motor ( ) which is drivably connected to the screw mechanism ( ), said screw mechanism ( ) providing a linear movement in response to a rotational movement of the motor ( ), and comprising a screw ( ) and a nut ( ) one of which is supported rotatably with respect to the housing ( ) by means of a rolling element bearing ( ). Support means ( ) have been provided which extend axially with respect to the screw mechanism ( ), said support means ( ) engaging the housing ( ), and supporting the screw mechanism ( ) so as to take up the axial loads exerted on said screw mechanism ( ).

Actuator having a central support, and brake calliper comprising such actuator

An asymmetric angular contact bearing comprises an inner ring ( ) and an outer ring ( ) each defining a raceway, at least one ring being provided with a high shoulder ( ) and a low shoulder ( ) which border the raceway of said ring, as well as a series of rolling elements ( ) which are in rolling contact with the raceways. The low shoulder is provided with a circumferential groove ( ), a ring member ( ) being accommodated in said groove ( ) for contacting the rolling elements ( ).

Asymmetric angular contact bearing

A system for supporting a shaft member at one end of a support component, including a bearing inner ring and a bearing outer ring, a row of rolling elements in the space between the rings, characterized in that the bearing outer ring (1,27, 34) has a radially outwardly directed flange (2) which can be fastened to the support component (9), the bearing inner ring (3), (32) having a radially inwardly directed flange 4 which can be fastened to the end surface of the shaft member (11), a cylindrical centering surface (15) on the bearing outer ring (1), (27), (34) for centering guidance in a corresponding bore in the support component (9), a cylindrical centering surface (13) on the bearing inner ring for centering guidance on a corresponding section of the shaft member (11).
