The other end for stating bearing chamber is provided with projection, and the reduction box output end is provided with groove, and the reduction box is matched somebody with somebody by groove and projection
Realization is closed to be connected with guide pipe integral piece；U-shaped block and bearing are provided with the bearing chamber, and the side wall of bearing chamber is provided with gear
Block hole, the bipod of the U-shaped block can be embedded in the block bore of bearing chamber.
Further, one end of the guide rod rivets with feed screw nut, and one end and the feed screw nut of the screw mandrel coordinate
Move in guide rod, and load together from the other end of guide pipe, and the other end of screw mandrel may pass through the bearing and electricity in bearing chamber
The rotating shaft connection of machine.
Further, in addition to PC parts, the PC parts are arranged between the guide pipe of guide rod and guide pipe integral piece, are used for
Prevent the abrasion between guide rod and guide pipe.
Further, the guide pipe integral piece uses integrated injection molding, is directed to pipe and bearing chamber injection is integral.
Compared with prior art, the present invention has advantages below：
1）Guide pipe integral piece material of the present invention employs working of plastics, and adds a certain amount of glass, ensure that intensity；
2）Guide pipe integral piece of the present invention is to utilize grinding tool injection molding, is integrally formed, and is directed to together with pipe does with bearing chamber,
The production efficiency and processing cost of raising, while the concentricity of strut guide pipe and bearing chamber is effectively guaranteed, it is further excellent
Change the structure of electric tail gate strut；
3）The spline structure of guide pipe integral piece and reduction box of the present invention can ensure that the stable performance of electronic strut, improve product peace
