Description

Technical Field

[0001] This utility model relates to the field of steering knuckle technology, and in particular to a lightweight automotive steering knuckle. Background Technology

[0002] Lightweight automotive steering knuckles are commonly used in the front axle of modern cars. As a key component of the steering system, they connect the wheels, steering tie rods, and suspension arms. Their function is to enable the wheels to steer precisely, transmit and bear various forces, and while ensuring the car's handling and stability, their reduced weight lowers energy consumption, improves fuel economy, and helps optimize the car's performance.

[0003] In practical applications, existing automotive steering knuckles, through the use of steering tie rods and kingpins, can meet the basic steering requirements of automobiles, but the following problems still exist:

[0004] Common automotive steering knuckles are often constructed by integrally casting thick components for strength considerations. During use, the heavy structure inevitably leads to a significant increase in the weight of the steering knuckle itself, which affects fuel consumption and is not conducive to energy conservation, emission reduction, and efficient operation of the vehicle. Therefore, this application provides a lightweight automotive steering knuckle to meet the requirements. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a lightweight automotive steering knuckle.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a lightweight automotive steering knuckle, comprising a steering knuckle body and a suspension arm boss disposed on the side of the steering knuckle body;

[0007] The load-reducing component is located on the top of the steering knuckle body. The load-reducing component includes a mounting boss fixedly connected to the side of the steering knuckle body. The top of the mounting boss has a first load-reducing groove and a gradient hollow groove. The inner cavity of the gradient hollow groove is provided with a shock-absorbing pad. The side of the mounting boss has a first limiting groove, and the side of the suspension arm boss near the steering knuckle body has a second limiting groove.

[0008] A shock-absorbing assembly is placed at the bottom of the steering knuckle body. The shock-absorbing assembly includes a fixing plate fixedly connected to the inner cavity of the steering knuckle body, and an anti-slip plate is provided at the bottom of the fixing plate.

[0009] In a preferred embodiment, the inner cavity of the first load-reducing groove is provided with a fixing frame, and the two ends of the fixing frame are respectively fixedly connected to the two sides of the inner wall of the mounting boss.

[0010] The technical effect of adopting the above technical solution is that by setting a fixing frame, additional support can be provided for the middle part of the mounting boss.

[0011] In a preferred embodiment, an elastic element is fixedly connected to the side of the damping pad, and a groove is provided in the inner cavity of the mounting boss. The end of the elastic element away from the damping pad is fixedly connected to the inner wall of the groove.

[0012] The technical effect of adopting the above technical solution is that by setting an elastic element, the stress caused by bumps can be buffered, and by setting a groove, the elastic element can be limited.

[0013] In a preferred embodiment, an anti-slip plate is fixedly connected to the bottom of the fixing plate, and a mounting base is fixedly connected to the inner cavity of the anti-slip plate.

[0014] The technical effect of adopting the above technical solution is that the anti-slip plate and the mounting base work together to support and protect the support plate and the spring sheet.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] In use, the shim is first placed in the inner cavity of the second limiting groove and the first limiting groove. Then, the steering knuckle body is installed on the side of the wheel hub through the threaded rod. The first limiting groove and the second limiting groove cooperate to restrict the position of the shim, thereby effectively improving the connection stability of the steering knuckle body. By opening the first and second reducing grooves, the load on the steering knuckle can be reduced, effectively reducing the overall weight of the steering knuckle and improving the fuel efficiency of the vehicle. When the vehicle is bumpy, the stress generated by the vibration is transmitted to the mounting boss through the wheel hub. At this time, the damping pad shrinks to a certain extent, thereby buffering the stress and preventing damage to the connection of the mounting boss during bumps. Attached Figure Description

[0025] 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.

[0026] like Figure 1 - Figure 4 As shown, this embodiment provides a technical solution: a lightweight automotive steering knuckle, a steering knuckle body 1, and a suspension arm boss 11 disposed on the side of the steering knuckle body 1;

[0027] The load-reducing component 2 is placed on the top of the steering knuckle body 1. The load-reducing component 2 includes a mounting boss 21 fixedly connected to the side of the steering knuckle body 1. The top of the mounting boss 21 is provided with a first load-reducing groove 22 and a gradient hollow groove 23. The inner cavity of the gradient hollow groove 23 is provided with a shock-absorbing pad 24. The side of the mounting boss 21 is provided with a first limiting groove 25, and the side of the suspension arm boss 11 near the steering knuckle body 1 is provided with a second limiting groove 28.

[0028] The shock absorber assembly 3 is located at the bottom of the steering knuckle body 1. The shock absorber assembly 3 includes a fixing plate 31 fixedly connected to the inner cavity of the steering knuckle body 1. An anti-slip plate 32 is provided at the bottom of the fixing plate 31. A fixing bracket 29 is provided in the inner cavity of the first damping groove 22. The two ends of the fixing bracket 29 are fixedly connected to the two sides of the inner wall of the mounting boss 21. An elastic element 26 is fixedly connected to the side of the damping pad 24. A groove 27 is provided in the inner cavity of the mounting boss 21. The end of the elastic element 26 away from the damping pad 24 is fixedly connected to the inner wall of the groove 27. A second damping groove 210 is provided at the top of the steering knuckle body 1. In use, the pad is first placed in the inner cavities of the second limiting groove 28 and the first limiting groove 25. Then, the steering knuckle body 1 is installed on the side of the wheel hub using a threaded rod. The limiting groove 25 and the second limiting groove 28 cooperate to restrict the position of the gasket, thereby effectively improving the connection stability of the steering knuckle body 1. By opening the first load-reducing groove 22 and the second load-reducing groove 210, the load on the steering knuckle can be reduced, effectively reducing the overall weight of the steering knuckle and improving the fuel efficiency of the vehicle. When the vehicle is bumpy, the stress generated by the vibration is transmitted to the mounting boss 21 through the wheel hub. At this time, the elastic element 26 contracts, thereby absorbing the stress. By cooperating with the damping pad 24 and the elastic element 26, the stability of the mounting boss 21 when bumpy can be effectively improved, and damage to the connection of the mounting boss 21 when bumpy can be avoided. By setting the groove 27, the position of the elastic element 26 can be limited.

[0029] Furthermore, such as Figure 2 and Figure 4 As shown: A sliding plate 32 is fixedly connected to the bottom of the fixed plate 31. A mounting base 33 is fixedly connected to the inner cavity of the sliding plate 32. A support plate 34 is fixedly connected to the side of the mounting base 33 away from the sliding plate 32. A spring piece 35 is fixedly connected to the side of the support plate 34. By setting the fixed plate 31, the sliding plate 32 can be supported. By cooperating with the fixed plate 31 and the sliding plate 32, additional support can be provided for the load-reducing hole opened at the bottom of the mounting boss 21. By cooperating with the support plate 34 and the spring piece 35, the stability of the mounting boss 21 can be further improved, effectively compensating for the reduction in strength caused by lightweighting.

[0030] During vehicle operation, foreign objects inevitably adhere to the side of the mounting boss 21, thus affecting the normal use of the shock absorber assembly 3, such as... Figure 4 As shown: In this solution, a guide groove 36 is provided on the side of the spring 35 away from the mounting base 33. By opening the guide groove 36, the attached foreign objects can be guided, thereby achieving the effect of discharging the foreign objects through bumps, and avoiding the foreign objects from adhering to the outer surface of the support plate 34 and affecting the shock absorption component 3.

[0031] Working principle:

[0032] like Figure 1-4 As shown:

[0033] In use: First, place the shim into the inner cavity of the second limiting groove 28 and the first limiting groove 25. Then, install the steering knuckle body 1 onto the side of the wheel hub using the threaded rod. The first limiting groove 25 and the second limiting groove 28 cooperate to restrict the position of the shim, thereby effectively improving the connection stability of the steering knuckle body 1. By opening the first reducing groove 22 and the second reducing groove 210, the load on the steering knuckle can be reduced, effectively reducing the overall weight of the steering knuckle and improving fuel efficiency. When the vehicle experiences bumps, the stress generated by the vibration is transmitted to the mounting boss 21 through the wheel hub. When the elastic element 26 contracts, it can absorb stress. Through the cooperation of the damping plate 24 and the elastic element 26, the stability of the mounting boss 21 during bumps can be effectively improved, and damage to the connection of the mounting boss 21 during bumps can be avoided. At the same time as the bumps occur, through the cooperation of the support plate 34 and the spring plate 35, the stability of the mounting boss 21 can be further improved, effectively compensating for the strength reduction caused by the lightweight. By opening the guide groove 36, the attached foreign objects can be guided, thereby achieving the effect of promoting the discharge of foreign objects through bumps.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
