Detailed Description
The following detailed description of the present invention is provided in connection with the accompanying drawings and the embodiments, and is not intended to limit the scope of the invention.
As shown in fig. 1, fig. 2 and fig. 3, the needle roller bearing pressing sleeve device for the left and right knuckle assemblies of the present embodiment includes a pressing seat 1, a pressing head 2 and a limiting sleeve 3, the pressing head 2 is a stepped shaft with a diameter gradually increasing from bottom to top, the limiting sleeve 3 is sleeved on the pressing head 2 from bottom to top, a second-stage stepped shaft is arranged outside the pressing head 2, a groove 11 is formed in the side wall of the pressing seat 1, the depth of the groove 11 is greater than the length of a long lug of the knuckle 4, a cylindrical boss 12 used for fixing a main pin hole of the knuckle 4 is arranged at the top of the pressing seat 1, a bolt 21 is sleeved on the inside of the pressing head 2, and the lower end of the bolt 21 is fixedly connected.
The utility model discloses the theory of operation: the main pin hole of the long lug of the steering knuckle is sleeved outside the boss 12 to fix the steering knuckle 4, and the short lug of the steering knuckle 4 is positioned inside the groove 11, so that the long lug or the short lug of the steering knuckle 4 is free from acting force when the needle roller bearing 5 is pressed and mounted, and the flange plate of the steering knuckle 4 can be prevented from being bent and deformed. The stop collar 3 cover is outside at the second level stepped shaft of pressure head, and the distance of restriction pressure head 2 downstream, and bearing 5 cover is outside at the first level stepped shaft of pressure head 2 lower extreme, and under the exogenic action, pressure head 2 with bearing 5 pressure equipment in the king pin hole of long ear, upward movement pressure head 2 shifts out pressure head 2 and bearing 5 separation. When the needle bearing 5 in the short lug main pin hole is pressed, the main pin hole of the short lug is sleeved outside the boss 21, the long lug is positioned inside the groove 11, the limiting sleeve 3 is sleeved outside the second-stage stepped shaft of the pressure head, and other operations are the same as the pressing process of the needle bearing 5 in the long lug main pin hole.
