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

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

An actuator comprises a housing, a motor ( ), an actuating member ( ) and a screw mechanism ( ) providing a linear movement of the actuating member ( ) with respect to the housing in response to a rotational movement of the motor ( ), which screw mechanism ( ) comprises a screw ( ) and a nut ( ) one of which is rotatably supported with respect to the housing by means of an angular contact bearing, and a reduction gear means ( ). The actuating member ( ) and the reduction gear means ( ) are situated at opposite ends of the screw mechanism ( ).

Modular actuator, and brake calliper comprising such actuator

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

An electric actuator ( ) comprises a housing ( ) which contains a screw mechanism ( ) and an electric motor ( ) which is driveably connected to the screw mechanism ( ), said screw mechanism ( ) providing a linear movement in a rotational movement of the electric motor ( ) and comprising a screw ( ) and a nut ( ), one of which is supported with respect to the housing ( ), a sensor ( ) being provided for measuring a quantity related to the rotational movement and/or the linear movement of the screw mechanism ( ). A control unit ( ) for monitoring and/or influencing the rotational and/or the linear movement of the screw mechanism ( ) on the basis of signals from the sensor ( ) has been provided.

Electric actuator with control sensor, and disc brake comprising such actuator

An actuator for use in a brake caliper is situated at opposite ends of a screw mechanism. A reduction gear mechanism is located at a distance from the actuating member. The reduction gear mechanism is included in a reduction gear module and a screw mechanism is contained in a screw mechanism module, which are interconnected through a drive module. The drive module may be located at the end of the reduction gear module facing away from the screw mechanism module. The modules may be axially aligned or at least two modules may be axially shifted or eccentric with respect to each other. The screw mechanism module may comprise an angular contact bearing which may be supported in a housing in different ways. The reduction gear module may be part of a planetary gear system.
