It is telescopic to be connected in screw rod bushing, flocking spring is set on the screw rod bushing, the outer cover of the flocking spring is equipped with fortune
Dynamic duct member, the movement duct member include covering to hold motion pipe on the flocking spring, and the lower motion pipe passes through surface
Raised line Joining clasp and upper connector inside groove coordinate, be slidably sleeved on inside upper connector, the upper connection
The one end of pipe far from lower connector is provided with the second bulb and sheath.
In order to enable epicyclic gearbox is unlikely to overweight, further, material is used by epicyclic gearbox middle gear
The plastic parts of plastic cement processing.
In order to preferably allow lower motion pipe mutually to be slided with upper motion pipe, further：In the outer of lower motion pipe
Surface is circumferentially arranged raised line, be upper motion pipe inner surface it is circumferentially arranged fluted.
In order to preferably reduce noise when friction, further：The material that above-mentioned flocking spring uses is polyamide
Fiber.
Compared with prior art, the usefulness of the utility model is：Simple in structure, batch production processing cost is low, row
Star gearbox drive is steady, and sound is small, can reduce relative motion friction between spring and screw rod bushing in electronic strut and produce
Raw huge noise problem effectively improves electronic strut overall performance.
