Description

Technical Field

[0001] This utility model relates to the field of wheel hub unit technology, specifically to a wheel hub unit pressing sealing ring and oil injection combination device. Background Technology

[0002] The wheel hub unit is the core component of the automotive wheel hub system, integrating components such as bearings and sealing structures. When installing the sealing ring in the wheel hub unit, an auxiliary device is required for pressing and installation, and its sealing performance must be ensured after installation.

[0003] For example, the manual installation device for a sealing ring disclosed in Chinese Patent CN112894705B includes an annular mounting body, a drive assembly, and a sealing ring assembly. The sealing ring assembly includes multiple linkage mechanisms connected end to end. The drive assembly has a force-applying part. The linkage mechanism includes rotating rods and connecting rods distributed circumferentially. The first point of the rotating rod is rotatably mounted on the annular mounting body. The second point of the rotating rod is slidably disposed on the connecting rod of the previous adjacent linkage mechanism. The third point of the rotating rod is hinged to the connecting rod of the next adjacent linkage mechanism. The end of the rotating rod is provided with a mounting post. Several mounting posts are used to fit the sealing ring. The end of the rotating rod of any linkage mechanism near the outer edge of the annular mounting body can be displaced and connected to the force-applying part. By driving a rotating rod to rotate through a drive component, the rod drives the connecting rod mechanism to rotate synchronously, thus achieving uniform support for the sealing ring. This method has low structural complexity and is less prone to local deformation of the sealing ring. Traditional sealing ring installation requires injecting lubricating oil first, and then installing the sealing ring. However, the above operations are basically done manually, which cannot be completed efficiently and with high quality. Therefore, a hub unit pressing sealing ring and oil injection combination device is proposed to solve the above problems. Utility Model Content

[0013] Preferably, the lifting assembly includes a second cylinder fixedly installed at the center of the top of the top frame, and the bottom end of the output shaft of the second cylinder is fixedly connected to the pressure frame. When the second cylinder on the top frame is activated, the pressure frame is pushed downward by the second cylinder, so that the pressure block at the bottom of the pressure frame presses the sealing ring.

[0014] Preferably, the bottom end of the pressure frame is provided with a plurality of pressure blocks and through slots, which are arranged in a ring and staggered with each other. The bottom end of the nozzle is inserted into the through slot, and lubricating oil is input through the lubricating oil delivery system, which then injects the lubricating oil through the connecting pipe and sprays it out through the nozzle at the bottom end of the delivery pipe.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a hub unit pressing seal ring and oil injection assembly device, which has the following beneficial effects:

[0017] By combining a pressure frame and a delivery pipe, lubricating oil is delivered into the hub unit through a nozzle at the bottom of the delivery pipe.
