Problems solved by technology
The automotive thrust rod joint with this structure has a certain degree of freedom in three-dimensional space, which is completely realized by the deformation of the elastic body. When the deformation exceeds the allowable range of the elastic body, the polyurethane elastic body will tear. The parts of the joint are easily deformed and damaged, which affects the service life
And its processing and assembly process is more complicated

The invention discloses an automobile thrust rod connector, having a columnar pin shaft, and characterized in that: a ball bush is outside the columnar pin shaft, a polyurethane elastomer is outside the ball bush, the outer end of the polyurethane elastomer is equipped with a gland, a composite wearable bush is between the columnar pin shaft and the ball bush, and the ball bush and the polyurethane elastomer as well as the gland are vulcanized into an organic whole. And the ball bush and the columnar pin shaft can freely and relatively rotate, thus reducing deformation of the polyurethane elastomer, and the polyurethane elastomer is uneasy to tear, prolonging the service life and making it simpler to machine and assemble.
Description
1. Technical field: [0001] The invention relates to an automobile thrust rod joint. 2. Background technology: [0002] At present, in the known technology, there is a kind of automobile thrust rod joint, which has a pin shaft with a spherical body, a polyurethane elastomer outside the spherical surface, a gland at the end of the polyurethane elastomer, the polyurethane elastomer and the pin The spherical body on the shaft and the vulcanization of the gland are integrated. The automotive thrust rod joint with this structure has a certain degree of freedom in three-dimensional space, which is completely realized by the deformation of the elastic body. When the deformation exceeds the allowable range of the elastic body, the polyurethane elastic body will tear. The parts of the joint are easily deformed and damaged, which affects the service life. And its processing and assembly process is more complicated. 3. Contents of the invention: [0003] The object of the present i...
