Abstract
The utility model relates to a structure of a front wheel turning pin boss, which comprises a pin boss ring in butt joint with a wheel hub inner ring through a middle annular boss body and a pair of pin bosses vertically connected at the inner side end of the pin boss ring. The structure is characterized in that a turning pin bushing and a needle roller bearing positioned on the inner periphery of the turning pin bushing are respectively connected with the upper side and the lower side of the pin boss; and a turning pin passes through the inner hole of the needle roller bearing and the center through hole of the pin boss main body to realize transmission connection with the turning pin boss. The structure of the front wheel turning pin boss can reduce friction and improve direction operability.
Description
Technical field
The utility model relates to a kind of front-wheel steering key seat structure.
Background technology
Automobile drives and turns to is one of major criterion of weighing automobile operating characteristic quality.At present, king pin and king pin lining all adopt the cliding friction form in the vehicle front king pin holder structure, and friction coefficient is big, and operability is poor.Therefore, how addressing the above problem is research object of the present utility model.
Summary of the invention
The purpose of this utility model is to provide a kind of front-wheel steering key seat structure, and this structure can be reduced friction, and improves the direction operability.
Its solution is: a kind of front-wheel steering key seat structure, comprise that it is characterized in that: the upper and lower sides of described key seat is connected with king pin lining and the needle bearing that is positioned on the king pin lining perimembranous through key seat seat ring that the middle part annular base body is docked with the wheel nave inner ring and a pair of key seat up and down that is connected on the key seat seat ring medial extremity; Described king pin passes the central through hole of needle bearing endoporus and key seat main body and realizes being in transmission connection with turning to key seat.
Advantage of the present utility model is: the utility model increases needle bearing between king pin and king pin lining, becomes the needle roller friction of rolling by traditional lining cliding friction between the two. turn to more flexible, more laborsaving.
