A linear actuator (1) and the centrifugal safety device (50) thereof is disclosed. The safety device (50) includes an outer socket (51) having a stop portion (512) and a first accommodation portion (513), an inner socket (53) having a raised portion (531) and a second accommodation portion (532) and a centrifugal assembly (55) having a centrifugal block (551) and an elastic element (555). The inner socket (53) drives the centrifugal assembly (55) to rotate. If the centrifugal force of the centrifugal block (551) is smaller than the elasticity of the elastic element (555), then the centrifugal block (551) is limited in the second accommodation portion (532) by the elastic element (555), or else the centrifugal block (551) moves into the first accommodation portion (513) and clamped by the raised portion (531) and the stop portion (512).

A spindle drive assembly for opening and/or closing a vehicle flap including a spindle drive assembly housing extending along a spindle drive axis and, between its axial ends, a stop section acting axially on both sides. A motor gear unit is arranged on a first side of the stop section and a spindle unit is arranged on a second side of the stop section. Furthermore, a vehicle flap with such a spindle drive assembly. In addition, a method of assembling a spindle drive assembly.

Disclosed is a linear actuator, including a housing, a drive worm, a rotating screw and a drive nut. The drive worm drives the rotating screw to rotate. The rotating screw rotates to drive the drive nut to move axially along the rotating screw. A clutch means is arranged between the drive worm and the rotating screw. The clutch means includes a coupling gear sleeve axially movable relative to the rotating screw. The rotating screw is sleeved with an axial limiting sleeve. The axial limiting sleeve and the housing are abutted axially. The axial limiting sleeve and the rotating screw maintain alignment in an axial direction. When the rotating screw is subjected to an axial load, the rotating screw transmits axial force to the housing through the axial limiting sleeve, and the axial force is not transmitted between the coupling gear sleeve and the axial limiting sleeve in the axial direction.

The electric motor (3) has a stator (4) and a rotor (5), the stator (4) being stationarily fixed at the housing (2), and the rotor (5) being rotatable relative to the stator (4) and rotationally fixed to a rotor carrier (6) supported relative to the housing (2) via a fixed bearing (7). The actuator device (1) further includes a threaded drive (8) having a nut (9) and a threaded spindle (10), with the nut (9) being rotationally driveable and axially fixed, and the threaded spindle (10) being axially displaceable along the threaded nut (9) and secured against rotation. The threaded nut (9) is rotationally fixed to the rotor carrier (6) and is at least partially radially within the fixed bearing (7).

Provided is an electric actuator, including: a driving motor (2); a motion conversion mechanism (6) configured to convert a rotary motion of the driving motor (2) to a linear motion; a transmission gear mechanism (5) configured to transmit a driving force from the driving motor (2) to the motion conversion mechanism (6); and a speed reduction mechanism (3) configured to reduce a speed of the rotary motion of the driving motor (2), and output the rotary motion reduced in speed to the transmission gear mechanism (5), wherein a side of one end portion of a rotation shaft (18) of a gear (16) of the transmission gear mechanism (5) is rotatably supported by a bearing (19), and a side of another end portion of the rotation shaft (18) of the gear (16) is rotatably supported by the output shaft (2a) of the driving motor (2).

An electromechanical cylinder contains a casing, an actuating rod mounted so as to be able to move longitudinally relative to the casing, an electric motor provided with a rotating rotor shaft, a mechanism for transforming a rotational movement of the rotor shaft of the electric motor into a linear translational movement of the actuating rod, and at least one bearing for guiding the rotor shaft of the electric motor in rotation relative to the casing and for supporting the rotor shaft. The cylinder further contains a sleeve that is fastened to the casing and inside which is mounted the bearing, and at least one load sensor that is mounted on the sleeve while being offset axially relative to the bearing.

Linear drive with a gear housing extending along a longitudinal axis, in which a spindle is rotatably mounted with a worm wheel connected to it in a rotationally fixed manner, a spindle nut running on the spindle, which is adjustable on the spindle between a retracted position and an extended position and which acts on a lifting tube. The spindle nut is arranged in the retracted position guide tube and retracted in the region of a rear end of the guide tube, and thus the lifting tube is also retracted into the guide tube. The spindle nut is arranged at a front end of the guide tube in the extended position. An electric motor drives the screw, which extends along a transverse axis extending transversely to the longitudinal axis, wherein the electric motor is accommodated in a motor housing which is connected to the gear housing. Furthermore, a control system is arranged in a control housing. In order to simplify the assembly of the control housing, a connection is formed between the control housing and the drive housing, which is designed in such a way that the latter is simultaneously electrically connected to the drive housing during the mechanical attachment.

A steering device of the present invention has a steered shaft rotation stopper (100) having a contact member (101) and a forcing member (102). The forcing member (102) forces at least either one of a steered shaft (6) or the contact member (101) in a direction in which the steered shaft (6) and the contact member (101) push against each other. In a state in which the contact member (101) contacts a contact portion (6D) of the steered shaft (6), the contact member (101) stops a rotation of the steered shaft (6).

An electric powered recirculating ball assembly includes a shaft having a plurality of sector teeth extending therefrom. The assembly also includes an eccentric sleeve defining a bore containing a portion of the shaft, the eccentric sleeve comprising an upper sleeve segment and a lower sleeve segment that are separate components, the eccentric sleeve defining an opening that the sector teeth extend through.

A drive member including a motor with a longitudinal axis and with at an actuating end a gear mechanism. A support member carries a displacement rod that is movably mounted on the support member. The motor is with its actuating end connected to the support member. The gear mechanism includes a hinge member allowing pivoting of the displacement rod about a pivot axis that is oriented transversely to the longitudinal axis. The gear mechanism engages with the displacement rod and the support member is hingingly attached to a fixation bracket in a hinge connection that is hingeable about an axis which is oriented transversely to the longitudinal axis. The drive member can be used for the adjustment of the backrest of a rear seat in a motor vehicle.
