    摘要: The invention relates to an actuator comprising a cylinder (1) in which a rod (2) is mounted to slide, the actuator having a screw (8) extending inside the rod to co-operate with a nut (7) secured to the rod, the screw being driven in rotation by a motor (10), the actuator being characterized in that a hydraulic chamber (CH) filled with hydraulic fluid is arranged inside the actuator by means of a floating piston (20) sliding in sealed manner against the rod inside of the actuator, the hydraulic chamber being in fluid flow communication with an accumulator (21) via a solenoid valve (22) that is controllable between a closed state in which the chamber is isolated from the accumulator, and a fluid-passing state in which the hydraulic chamber and the accumulator are in communication, calibrated resistance being exerted against the passage of fluid from the chamber towards the accumulator.

    摘要: A ball screw with support devices includes a nut base having two sides equipped with the support devices for preventing the screw from deflection. Two runner structures are provided near two ends of the screw. The runner structure includes a driving wheel and a driven wheel having different diameters and concentrically installed. The nut base is connected to the driving wheel via an active connecting element for driving the driving wheel to rotate. The driven wheel moves with the driving wheel and is connected to the support devices via passive connecting elements so that the support devices and the nut displace synchronously. By controlling a diameter ratio between the driving and driven wheels, the nut and the support devices displace with proportional speeds, thereby allowing the support devices to always stay at the two sides of the nut as designed and provide reliable support.

    摘要: A spindle drive for longitudinally adjusting a motor vehicle seat is provided. The spindle drive comprising an adjustment rail that can be longitudinally adjusted relative to a body mounted rail and an adjusting mechanism that includes a driving worm connected to a driving device as well as a spindle nut, the external teeth of which mesh with the external teeth of the driving worm, and the internal teeth of which mesh with the external thread of a spindle. The spindle nut is formed by a hybrid spindle nut that has a functional part, which is located in the force flux between the driving worm and the spindle, and at least one strengthening part, deflecting crash forces from the adjustment rail into the spindle.

    摘要: A transmission mechanism includes a screw mandrel and a transmission assembly. The transmission assembly includes a first transmission member, a fixing member, a second transmission member, a first magnetic member, and a second magnetic member. The first transmission member is screwed with the screw mandrel. The fixing member is fixedly-connected to the first transmission member. The second transmission member is screwed with the screw mandrel and resisting against the fixing member to avoid rotating relative to the first transmission member. The first magnetic member is fixedly mounted on the fixing member. The second magnetic member is fixedly mounted on the first transmission member towards the first magnetic member to interact with the first magnetic member.
