Description

Technical Field

[0001] This utility model relates to the field of oil injection equipment technology, and more specifically, to an oil injection device for a dust cover of a drive shaft outer ball cage. Background Technology

[0002] The drive shaft outer CV joint dust cover is a component of the automotive steering drive axle. Its main function is to prevent dust, mud, and other debris from entering the CV joint, thereby protecting the lubricating oil inside the CV joint from contamination and ensuring the normal operation of the CV joint. The drive shaft outer CV joint dust cover needs to be filled with oil, and after filling with oil, the drive shaft outer CV joint dust cover is fastened onto the drive shaft housing.

[0003] However, since most existing drive shaft outer CV joint dust cover oil injection pipes are simple, ordinary tubular structures, such as Figure 5 As shown, the oil outlet end is difficult to extend smoothly into the dust cover of the outer CV joint of the drive shaft, and the overall length of the oil injection pipe is relatively short, resulting in a shallow insertion depth into the dust cover of the outer CV joint of the drive shaft, which poses a significant risk of grease overflow and affects the reliability of use. Based on this, this utility model designs an oil injection device for the dust cover of the outer CV joint of the drive shaft to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an oil injection device for the dust cover of the drive shaft outer ball cage, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A lubrication device for a dust cover of a drive shaft outer ball cage includes a support base, a vertical frame, a T-shaped seat, and an oil injection extension pipe. The vertical frame is fixedly connected to the upper end of the support base. The T-shaped seat is fixedly installed on the top side of the vertical frame by fastening bolts. An oil injection pump is fixedly installed at the bottom of the T-shaped seat. An oil inlet assembly is connected to the inlet end of the oil injection pump. An oil guide bend is fixedly connected to the outlet end of the oil injection pump. The oil injection extension pipe is fixedly connected to the bottom end of the oil guide bend. The cross-sectional shape of the oil injection extension pipe is conical, and the diameter of the oil outlet end of the oil injection extension pipe is smaller than the diameter of the oil inlet end.

[0007] As a preferred embodiment of this utility model, the oil inlet assembly includes an oil inlet pipe and a flange, with the flange fixedly disposed at the end of the oil inlet pipe.

[0008] As a preferred embodiment of this utility model, the number of fastening bolts is four, and the fastening bolts are spaced apart at each end corner of the end face of the T-shaped seat.

[0009] As a preferred embodiment of this utility model, the T-shaped seat has a side groove on its side, and the end cap of the fastening bolt is located in the side groove.

[0010] As a preferred embodiment of this utility model, the surface of the support base is provided with mounting holes, which are distributed at each corner of the surface of the support base.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention utilizes a tapered oil injection extension pipe, with the outlet diameter being smaller than the inlet diameter, allowing the extension pipe to easily and smoothly extend into the dust cover of the drive shaft's outer CV joint. The combination of the guide bend and the extension pipe forms the oil injection pipe, which helps extend the overall length of the pipe, thus ensuring the correct insertion depth into the dust cover of the drive shaft's outer CV joint. This effectively reduces the risk of grease overflow and provides good reliability. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 5 As shown, this utility model provides an oil injection device for the dust cover of the outer CV joint of the drive shaft, including a support base 1, a stand 2, a T-shaped seat 3, and an oil injection extension pipe 701. The stand 2 is fixedly connected to the upper end of the support base 1. The T-shaped seat 3 is fixedly installed on the top side of the stand 2 by fastening bolts 4. An oil injection pump 5 is fixedly installed at the bottom of the T-shaped seat 3. An oil inlet assembly 6 is connected to the inlet end of the oil injection pump 5. An oil guide bend 7 is fixedly connected to the outlet end of the oil injection pump 5. The oil injection extension pipe 701 is fixedly connected to the bottom end of the oil guide bend 7. The cross-sectional shape of the oil injection extension pipe 701 is conical. The diameter of the oil outlet end of the oil injection extension pipe 701 is smaller than the diameter of the oil inlet end, so that the oil injection extension pipe 701 can easily and smoothly extend into the dust cover 8 of the outer CV joint of the drive shaft.

[0021] Among them, such as Figure 2 As shown, the oil inlet assembly 6 includes an oil inlet pipe 601 and a flange 602. The flange 602 is fixedly installed at the end of the oil inlet pipe 601, and the oil inlet pipe 601 can be connected to the corresponding oil supply pipeline.

[0022] Among them, such as Figure 1 As shown, there are four fastening bolts 4, which are spaced apart at the corners of the end face of the T-shaped seat 3, thus ensuring the stability of the T-shaped seat 3 on the support frame 2.

[0023] Among them, such as Figure 4 As shown, the T-shaped seat 3 has a side groove 301 on its side, and the end cap of the fastening bolt 4 is located in the side groove 301, which achieves the purpose of hiding the fastening bolt 4.

[0024] Among them, such as Figure 1 As shown, mounting holes are provided on the surface of the support base 1. The mounting holes are distributed at each corner of the surface of the support base 1, so as to achieve the purpose of positioning and mounting the support base 1.

[0025] The working principle of this utility model:

[0026] During use, the dust cover 8 of the outer CV joint of the drive shaft is opened on the drive shaft housing 9. The oil injection extension pipe 701 has a tapered cross-section, and the diameter of the oil outlet end of the oil injection extension pipe 701 is smaller than the diameter of the oil inlet end, so that the oil injection extension pipe 701 can be easily and smoothly extended into the dust cover 8 of the outer CV joint of the drive shaft. The oil guide bend 7 and the oil injection extension pipe 701 are combined to form an oil injection pipe, which helps to extend the overall length of the oil injection pipe, thereby ensuring the depth of insertion into the dust cover 8 of the outer CV joint of the drive shaft. This can effectively reduce the risk of grease overflow. The grease is drawn out by the oil injection pump 5 and finally injected into the dust cover 8 of the outer CV joint of the drive shaft through the oil guide bend 7 and the oil injection extension pipe 701. After the oil injection is completed, the dust cover 8 of the outer CV joint of the drive shaft is removed and put on the drive shaft housing 9.
