Description

Technical Field

[0001] This utility model relates to the field of chassis bracket technology, specifically a main support bracket for chassis suspension. Background Technology

[0002] The MacPherson independent suspension is one of the most widely used suspensions in passenger cars. The main structure of the MacPherson suspension consists of a coil spring (equivalent to the shock absorber spring in this application) and a shock absorber. The bottom of the coil spring is supported by a bracket (commonly known as the lower control arm), which is the main support structure of the entire suspension.

[0003] Because the spring rests against the bracket for extended periods, and the bracket is exposed to the environment for long periods, it will corrode, especially at the contact point between the bracket and the spring. Firstly, the spring and bracket are made of different materials, leading to galvanic corrosion. Secondly, the small contact area between them makes the contact point highly susceptible to corrosion. Furthermore, the vehicle's weight and impacts gradually weaken the support arm, making it susceptible to breakage or penetration by the spring. Therefore, we propose a main support bracket for the chassis suspension. Utility Model Content

[0004] This utility model provides a main support bracket for chassis suspension, which has the advantage of high structural strength and solves the problems mentioned in the background art.

[0005] The technical solution of this utility model is implemented as follows: a main support bracket for chassis suspension includes a base, with support arms on both sides of the base, a support plate detachably provided on the top of the base, a spring fixing groove on the top of the support plate, and a planar contact between the support plate and the top of the base.

[0006] Preferably, each arm has a connecting seat at its end.

[0007] Preferably, the support plate and the carriage are connected by a locking bolt, and the free end of the locking bolt is fastened by a fastening nut.

[0008] Preferably, a limiting post is provided at the center of the spring fixing groove, and a through hole is provided at the center of the limiting post; a first mounting hole corresponding to the position and the through hole is provided on the top of the support, and the locking bolt is located in the first mounting hole and the through hole.

[0009] Preferably, a plurality of second mounting holes are provided around the first mounting hole, and a limiting block corresponding to each of the second mounting holes is provided at the bottom of the support plate, with the limiting block placed inside the second mounting hole.

[0010] Preferably, the bottom of the support is provided with a cavity, and a fixed seat is provided at the center of the cavity. The side of the fixed seat is connected to the support through multiple first reinforcing seats.

[0011] Preferably, a second reinforcing seat is provided on both sides of the cavity, which is used to strengthen the structural strength between the support arm and the support seat.

[0012] Preferably, the first mounting hole is located at the fixed base, and the second mounting hole is located at each of the first reinforcing bases.

[0013] Compared with the prior art, in use, the support plate and the top of the support seat are in planar contact, and the support plate supports the shock-absorbing spring. This reduces the pressure of the shock-absorbing spring on the support seat and avoids the shock-absorbing spring directly pressing against the support seat. It also avoids galvanic corrosion caused by the shock-absorbing spring acting directly on the support seat, thus protecting the support seat well. Moreover, the air spring can be directly installed when the support plate is removed. Attached Figure Description

Detailed Implementation

[0022] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figures 1 to 6 This utility model provides a technical solution: a main support bracket for chassis suspension, including a support base 1, with support arms 2 on both sides of the support base 1, and connecting seats 6 at the ends of the support arms 2. The connecting seats 6 are respectively connected to the vehicle frame and the wheel yoke. The support arms 2 can appear in two sets, with each set consisting of two support arms 2, as detailed below. Figure 1 and Figure 6 As shown, of course, the support arm 2 can also be two arms and set on both sides of the support 1.

[0024] To reduce the overall weight of the support, the bottom of the support 1 was designed as a cavity 14, as shown below. Figure 5 As shown, a fixed seat 16 is provided at the center of the cavity 14. The side of the fixed seat 16 is connected to the support 1 through multiple first reinforcing seats 15. The multiple first reinforcing seats 15 form a cross-shaped, cross-shaped, or rice-shaped structure, which can effectively enhance the load-bearing capacity and deformation resistance of the support 1. For example... Figure 5 As shown, a second reinforcing seat 13 is provided on both sides inside the cavity 14. The second reinforcing seat 13 can be connected to the end of the first reinforcing seat 15, so that the first reinforcing seat 15 and the second reinforcing seat 13 also form an integral structure. The second reinforcing seat 13 is used to strengthen the structural strength between the support arm 2 and the support seat 1. Specifically, it increases the thickness at the connection between the support arm 2 and the support seat 1.

[0025] In this application, the chassis's shock-absorbing springs are mounted on top of the trailer 1, such as... Figure 1 and Figure 2 As shown, a support plate 3 is detachably provided on the top of the support base 1. The top of the support plate 3 is provided with a spring fixing groove 17. A limiting post 4 is provided at the center of the spring fixing groove 17. A through hole 11 is provided at the center of the limiting post 4. A first mounting hole 8 corresponding to the position of the through hole 11 is provided on the top of the support base 1. The support plate 3 and the support base 1 are connected by a locking bolt 7. The locking bolt 7 is placed in the first mounting hole 8 and the through hole 11. The free end of the locking bolt 7 is fastened by a fastening nut 10. In this way, the support plate 3 can be firmly fixed on the top of the support base 1. like Figure 1 and Figure 2As shown, the bottom of the shock-absorbing spring 5 is fitted onto the limiting post 4 and placed within the spring fixing groove 17. The shock-absorbing spring 5 of the chassis is always in a compressed state, so the shock-absorbing spring 5 is placed within the spring fixing groove 17 with a certain pressure and will not loosen. It should be noted that the top of the support plate 3 and the drag seat 1 are in planar contact, maximizing the contact area between the support plate 3 and the drag seat 1. This reduces the pressure of the shock-absorbing spring 5 on the drag seat 1 and also prevents the shock-absorbing spring 5 from directly pressing against the drag seat 1. Even if the drag seat 1 is corroded, the support plate 3 can still support the spring. When the support plate 3 is corroded to its limit, it can be replaced separately. The above-mentioned method also has the advantage that the materials of the shock-absorbing spring 5 and the support 1 are different. If the support 1 and the shock-absorbing spring 5 are in direct contact, the contact area will inevitably be corroded first. This is not only because the contact area is relatively large, but also because of galvanic corrosion. However, in this application, the shock-absorbing spring 5 is placed on the support plate 3, which avoids the above situation and thus effectively protects the support 1.

[0026] Furthermore, based on the above embodiments, a plurality of second mounting holes 9 are provided around the first mounting hole 8, and a limiting block 12 corresponding to each second mounting hole 9 is provided at the bottom of the support plate 3. The limiting block 12 is placed inside the second mounting hole 9, which can increase the stability of the support plate 3. like Figure 5 As shown, the first mounting hole 8 is set at the fixed seat 16, and the second mounting hole 9 is set at each of the first reinforcing seats 15. The mounting holes not only serve to fix the support plate 3, but also further reduce the weight of the bracket, without affecting the overall strength of the bracket. Because of the second mounting hole 9, the bracket proposed in this application can be used to install both the shock-absorbing spring 5 and an air spring, such as... Figure 6 As shown, when installing an air spring, simply remove the support plate 3 and install it directly on top of the support base 1. Since the two ends of the air spring are supports and the air chamber is between the supports, the supports can be directly fastened to the second mounting hole 9 or the first mounting hole 8 with bolts. This makes it convenient to install the car shock absorber.

[0027] Based on the above embodiments, further optimization can be achieved by providing a sealing rubber gasket between the support plate 3 and the support seat 1.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
