Automobile steering transition rocker arm assembly

Abstract

The invention relates to an automobile steering transition rocker arm assembly which comprises a rocker arm bracket, a transition rocker arm, a rocker arm shaft, a lining and a fixing nut. A rocker arm shaft perforation is formed in the upper end of the transition rocker arm; the lining is fixed in the rocker arm shaft perforation; the rocker arm bracket comprises a rocker arm shaft connecting part and a rocker arm bracket fixing part; an opening is formed in the lower end of the rocker arm shaft connection part; the upper end of the transition rocker arm is movably arranged in the opening; the rocker arm shaft penetrates through a rocker arm shaft through hole and the lining and then is fastened through a fixing bolt; the rocker arm bracket fixing part is fixedly connected with the inner side wall of the rocker arm bracket; and a rocker arm bracket mounting hole is formed in the rocker arm bracket fixing part. According to the automobile steering transition rocker arm assembly, by improving the rocker arm bracket structure, the two ends of the rocker arm shaft are subjected to the same supporting force, the force-bearing points of the rocker arm shaft and the lining are basically uniform, the abrasion speed between the rocker arm shaft and the lining is reduced, and deformation of the rocker arm shaft is relieved.

Description

technical field [0001] The invention belongs to the technical field of automobile steering systems, in particular to an automobile steering transition rocker assembly. Background technique [0002] At present, the structure of the double front axle steering transition rocker bracket assembly is as follows: figure 1 As shown, the rocker arm bracket 1 is cast, the material is QT450, and has six bolt holes, the rocker arm shaft 2 is a forged part, the material is 40Cr, two gaskets 3 are respectively located at both ends of the rocker arm 4, and the bushing 5 is pressed in In the rocker hole, the block 6 is located between the channel nut 7 and the washer. [0003] In the prior art, one end of the rocker arm shaft is fixed to the rocker arm bracket, and the other end is suspended in the air, resulting in uneven stress on the inner bushing of the rocker arm. Because the rocker shaft is assembled on the rocker bracket in the form of a cantilever, and one end is stressed, the bus...
