Description

Technical Field

[0001] The invention relates to the technical field of vehicles, and in particular to a special disassembly device for a wheel hub bearing assembly. Background Art

[0002] New electric wheel-side drive devices are often used in vehicle production. Therefore, when maintaining the electric wheel-side drive device, it is necessary to remove it from the vehicle, place it on the operating table and then disassemble it. When disassembling, first remove the parts that are easy to disassemble on the periphery, and then separate the wheel hub bearing assembly and the motor assembly. The assembly relationship between the upper wheel hub bearing assembly and the lower motor assembly is an interference fit between the hole and the shaft. It takes a lot of force to separate them, and it cannot cause damage to the product. Ordinary tools cannot achieve this. Therefore, it is necessary to design a special disassembly device with a small size, simple and reasonable structure, reliable strength and rigidity, easy operation, high efficiency, long life, and low manufacturing cost for after-sales personnel to carry and use when they go out to maintain the product.

[0019] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0020] like Figures 1 to 4 As shown, this embodiment provides a special disassembly device for a wheel hub bearing assembly, which is used to separate the wheel hub bearing assembly 10 from the motor assembly 20, and specifically includes a connector 1, a jack 5, a support seat 6, and a push pin 7. The connector 1 is fixedly connected to the wheel hub bearing assembly 10, and the support seat 6 is arranged below the connector 1. The jack 5 is fixedly installed on the top of the support seat 6, and the push pin 7 is installed on the bottom of the support seat 6. The bottom of the push pin 7 passes through the wheel hub bearing through hole of the wheel hub bearing assembly 10 and is supported on the upper end surface of the upper end cover of the motor assembly 20.

[0021] In this embodiment, a lifting eye screw 3 is installed on the top of the connector 1 .

[0022] In this embodiment, the connecting body 1 is fixedly connected to the wheel hub bearing assembly 10 via a pressure plate 8 and bolts on the upper portion of the wheel hub bearing assembly 10 .

[0023] In this embodiment, the connector 1 includes two ear plates 11 arranged in a cross shape, a connecting column 12 is fixed at each end of the ear plate 11, a ring plate 13 is connected to the lower end of the connecting column 12, and a circular plate 14 is fixed under the ear plate 11. The various parts can be connected by welding, wherein the circular plate 14 is the position where the oil cylinder head is supported, and plays a reinforcing role.

[0024] In this embodiment, the top of the support seat 6 is fixedly connected to the jack 5 via screws 2 and a cover plate 4 to ensure that the position of the jack 5 is fixed and stable during use.

[0025] In this embodiment, a threaded hole for installing the ejector pin 7 is provided at the bottom of the support seat 6 .

[0026] The working principle of the above structure is:

[0027] During operation, after the device 0 is assembled according to the above-mentioned assembly relationship and connected to the product, the jack 5 is operated to lift the connector 1 upward. Since the connector 1 is fixedly connected to the wheel hub bearing assembly 10 as a whole, it will drive the wheel hub bearing assembly 10 to move upward, and the motor assembly 20 below is supported downward by the combination of the screw 2, cover plate 4, jack 5, support seat 6, and push pin 7. Finally, the wheel hub bearing assembly 10 and the motor assembly 20 can be separated. Then, use the lifting equipment to lift the lifting eye screw 3 to lift the assembly of the connector 1 and the wheel hub bearing assembly 10 onto the operating table and place it. The special device is separated from the product, and then subsequent maintenance operations are performed.
