[0027] The five shock-absorbing dampers 61 at the four corners and the center evenly absorb the vibration force, greatly improving the shock-absorbing performance of the bearing seat and increasing the service life of the bearing seat and the bearing.

The rotation of the driving ring 8 drives the clamping column 7 to slide. Compared with the friction between the clamping column 7 and the bearing caused by directly rotating the clamping column 7, the clamping column 7 is linearly slidably abutted against the bearing, reducing the wear on the bearing. The top surface of the upper seat body 3 is in the form of an arc groove, which is convenient for operating the driving column. The clamping column 7 is extended along the radius of the mounting groove. The uniformity and reliability of the clamping force are improved.

[0034] The implementation principle of a damping type steering gear bearing seat die casting in the embodiment of the present application is:

[0035] First, install the lower seat body 2 of the bearing seat from top to bottom on the support plate 5, so that the top end of the guide rod 62 passes through the guide hole 11 and the bottom surface of the bottom plate 1 abuts against the top surface of the shock-absorbing pad 1 63, then pass the shock-absorbing pad 2 64 onto the guide rod 62, and then rotate the limit nut 65 until it abuts against the top surface of the shock-absorbing pad 2 64, and finally fix the top end of the shock-absorbing damper 61 to the bottom plate 1 through the connecting bolt 611, that is, the lower seat body 2 is fixed, and then the bearing is placed in the lower arc groove 21 of the lower seat body 2, and then the upper seat body 3 is installed on the lower seat body 2. The second plate body 42 is fitted with the first plate body 41, and then the fixing nut 44 is tightened onto the fixing bolt 43. Finally, the driving ring 8 is rotated to make the clamping column 7 clamp the bearing, thereby further improving the connection tightness between the bearing and the bearing seat, making it difficult for the bearing to be offset from the bearing seat. With the cooperation of the shock-absorbing damper 61, the guide rod 62, the shock-absorbing pad 1 63 and the shock-absorbing pad 2 64, the shock-absorbing performance of the bearing seat is greatly improved, making it difficult for the bearing seat as a whole to shake during use, thereby increasing the service life of the bearing seat and the bearing.
