This strut assembly is made up of pin, sliding sleeve, spring and base, and one end of described sliding sleeve is the gear that centre has through hole
Plate, is provided with pin in this through hole, the other end of sliding sleeve is fixed with base, and described spring is positioned at surrounded by sliding sleeve and base
In cavity；
Described pin has spherical protuberance, and the bottom of spherical protuberance is extended axially by an annular flange portion, described
The upper surface of annular flange portion offsets with the baffle plate back side, described spherical protuberance and through hole interference fit, and part stretches out through hole；
Described base has blind hole, and the opening part of base has flange, and described sliding sleeve end has and catches on this flange
Fore shaft crimp so that this strut assembly is integrally formed.
Further, the bottom of described pin offers blind hole I isometrical with blind hole, and the centrage of described blind hole I is with blind
The centrage in hole is on the same line.
Further, described spring is between blind hole and blind hole I.
Further, described sliding sleeve is provided with the width of baffle plate I, described baffle plate I and baffle plate near the outer circumferential side of fore shaft crimp
Equal, the length of the baffle plate length more than baffle plate I.
Further, the edge, upper surface of described baffle plate I is provided with outer chamfering.
The beneficial effects of the utility model are: this utility model adds base on the basis of existing technology, and base,
Pin, sliding sleeve and spring are integrally formed the strut assembly of formula, effectively improve installation time, improve the strong of tooth hub simultaneously
Degree, is effectively guaranteed the service life of product.
