Front axle steering knuckle arm structure

Abstract

The utility model discloses a front axle steering knuckle arm structure, which relates to the field of steering knuckles, and comprises an axle seat, the outer side of the axle seat is also connected with a first knuckle arm, a second knuckle arm and a third knuckle arm, the side surface of the second knuckle arm is provided with a cover plate, and the second knuckle arm is internally provided with a groove matched with the cover plate and used for installing an ABS (Anti-lock Brake System). And a third section arm is arranged on the side face of the third section arm, and a connecting pipe is arranged on the inner wall of the third section arm. By arranging the third knuckle arm, when the steering knuckle is installed, the steering knuckle and an external structure extrude the spring through the spring arranged on the outer side of the connecting pipe, so that the spring generates counter-acting force, the steering knuckle can be pushed by the elastic force of the spring to extrude the bolt, and therefore the steering knuckle can be installed conveniently. Therefore, friction force between the steering knuckle and the bolt is increased, and stability of connection between the bolt and the steering knuckle is improved.

[0012] The present invention is further configured such that a fixing groove is provided at the top end of the second arm section, and the fixing groove is aligned with the groove in the second arm section.

[0013] By adopting the above technical solution, the ABS can be easily limited and fixed.

[0014] The present invention is further configured such that a fixing bolt is installed at the edge of the cover plate, and the cover plate is fixedly connected to the second arm via the fixing bolt.

[0015] By adopting the above technical solution, the cover plate can be easily installed.

[0016] The utility model is further configured such that the connecting pipe port is aligned with the outer wall of the third arm, the outer wall of the third arm is provided with an inward-concave groove, and the inward-concave groove is arranged around the connecting pipe, a rubber gasket and a metal gasket are installed on the inner wall of the inward-concave groove, the end of the spring is inserted into the interior of the inward-concave groove, and the rubber gasket fixes the end of the spring, and the metal gasket squeezes and fixes the rubber gasket.

[0020] In summary, the present invention has the following beneficial effects:

[0021] 1. The utility model can conveniently fix the ABS by providing the second arm and the cover plate. When fixing, the ABS is installed in the second arm to isolate the ABS from the outside, thereby reducing the contamination of the ABS. Subsequently, the ABS is limited by the cover plate to maintain the stability of the ABS.

[0022] 2. The utility model provides a third arm. When the steering knuckle is installed, the spring provided on the outside of the connecting tube can be used to squeeze the spring between the steering knuckle and the external structure, so that the spring generates a reaction force. The elastic force of the spring pushes the steering knuckle to squeeze the bolt, thereby increasing the friction between the steering knuckle and the bolt, thereby improving the stability of the connection between the bolt and the steering knuckle.

The end of the spring 5 is inserted into the inside of the concave slot 402, and the rubber gasket 403 fixes the end of the spring 5, and the metal gasket 404 squeezes and fixes the rubber gasket 403. The connecting tube 401 is installed with the spring 5 through a fixed structure. During the installation process, when the third section arm 4 is connected, the spring 5 located on the outside of the connecting tube 401 will be squeezed first, and then fixed to the thread in the connecting tube 401 through bolts, and at the same time fixed to the external structure (frame, etc.). At this time, the external structure will squeeze the spring, and the force of the spring will push the bolt to be tightly fixed to the connecting tube 401.

[0032] See also Figure 1 and Figure 2 Threaded holes are provided in the middle parts of the first section arm 2, the second section arm 3 and the third section arm 4. The threaded hole of the third section arm 4 is located inside the connecting pipe 401, which is convenient for installing the steering knuckle.

[0033] See also Figure 3 A fixing bolt is installed on the edge of the cover plate 301, and the cover plate 301 is fixedly connected to the second arm 3 through the fixing bolt. A support plate 3011 is provided on the side of the cover plate 301, and a slot 3012 is provided on the top of the support plate 3011. The slot 3012 fixes the ABS. A connector 3013 is installed on the side of the cover plate 301, and the connector 3013 is connected to the slot 3012, which is convenient for connecting the cover plate 301 to the ABS.

[0034] See also Figure 5 This is the second embodiment of the present application. The difference from the first embodiment is the installation structure of the spring. Specifically, the port of the connecting pipe 401 protrudes from the outer wall of the third arm 4, and multiple groups of external protruding grooves 4011 are installed on the edge of the protruding portion of the connecting pipe 401. The spring 5 is fixed to the third arm 4 through the external protruding grooves 4011, which can facilitate the installation of the spring.

[0035] When using the steering knuckle, first install the sensor inside the second arm 3, install the ABS inside the cover plate 301, and connect the ABS to the external power supply through the connector 3013. Then, insert the cover plate 301 into the slot on the side of the second arm 3 to limit and fix the ABS. The cover plate 301 is fixed with fixing bolts to isolate the ABS from the external environment and reduce contamination to the ABS. When fixing the steering knuckle, the bolts will pass through the second arm 3 and then be inserted into the slot in the second arm 3 to further fix the ABS.

[0036] During use, the structure is installed through each group of arms. During the installation process, when the third arm 4 is connected, the spring 5 located on the outside of the connecting pipe 401 will be squeezed first, and then fixed to the thread inside the connecting pipe 401 through bolts, and at the same time fixed to the external structure (frame, etc.). At this time, the external structure will squeeze the spring, and the force of the spring will push the bolt to be tightly fixed to the connecting pipe 401. When shaking occurs, the stability is improved by increasing the friction between the bolt and the connecting pipe 401.
