Description

Technical Field

[0001] This utility model relates to the field of automotive technology, specifically to a lower control arm for an automotive suspension shock absorber. Background Technology

[0002] In automotive suspension design, the double wishbone suspension, a common front suspension structure, offers good handling performance. In this type of suspension, the lower end of the shock absorber is connected to the control arm, and the typical design connection method uses a support arm.

[0003] While existing lower control arms can connect and support the suspension shock absorbers of automobiles, their rigidity is poor, leading to breakage due to excessive pressure during impacts. Furthermore, prolonged use can cause material fatigue and deformation, resulting in wheel misalignment and vehicle drift. Therefore, a new type of lower control arm for automobile suspension shock absorbers is proposed. Utility Model Content

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The lower control arm of this automotive suspension shock absorber is made of polyurethane, which makes the bushing more wear-resistant and aging-resistant during use. It also has better high and low temperature resistance. It is fixedly assembled with the lower control arm body through a sealing block and a sealing ring. The sealing block and sealing ring fit closely to the outer wall of the ball joint, which effectively reduces the intrusion of dust and moisture into the ball joint during use and prevents steering play caused by wear of the ball joint.

[0013] 2.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 - Figure 5 A lower control arm for an automotive suspension shock absorber includes a lower control arm body 1, a rigid component 2 on the outer wall of the lower control arm body 1, a placement groove 4 on the inner wall of the lower control arm body 1, a rubber sleeve 5 placed on the inner wall of the placement groove 4, a ball head 3 placed on the inner wall of the lower control arm body 1, and a sealing block 6 and a sealing ring 7 fixedly assembled on the lower control arm body 1.

[0023] In the above structure, the rubber sleeve 5 is made of polyurethane, which gives it better wear resistance and aging resistance during use. At the same time, the rubber sleeve 5 also has better high and low temperature resistance. By fixing the sealing block 6 and the sealing ring 7 to the lower fork arm body 1 and making the sealing block 6 and the sealing ring 7 fit against the outer wall of the ball head 3, the ball head 3 can effectively reduce the intrusion of dust and moisture during use, thereby preventing the ball head 3 from having steering play due to wear.

[0024] In a preferred embodiment: the rigid component 2 includes a fixing block 201, a limiting rod 202 is fixedly mounted on the top of the fixing block 201, an arc-shaped rod 203 is rotatably connected to the limiting rod 202, a fixing rod 204 is fixedly mounted on the top of the arc-shaped rod 203, a connecting block 205 is fixedly mounted on the end of the arc-shaped rod 203 away from the limiting rod 202, a placement block 206 is provided on the outer wall of the connecting block 205, a rotating column 207 is rotatably connected to the placement block 206, and a connecting rod 208 is rotatably connected to the fixing rod 204;

[0025] In the above structure, when the lower fork body 1 is impacted, pressure is applied to the frame via the lower fork body 1, causing the placement block 206, rotating column 207, connecting block 205 and arc rod 203 to perform tensioning operation on the lower fork body 1, ensuring that the lower fork body 1 does not deform when subjected to impact force. At the same time, the two arc rods 203 are supported and connected by the fixing rod 204 and connecting rod 208, so that the arc rods 203 do not slacken after being subjected to pressure, thereby improving the rigidity of the lower fork body 1.

[0026] In a preferred embodiment: both the placement block 206 and the fixing block 201 are fixedly assembled to the outer wall of the lower fork arm body 1, and the connecting block 205 is fixedly assembled to the rotating column 207.

[0027] In the above structure, the rigid component 2 is limited by the lower fork arm body 1, making the rigid component 2 more stable when placed, and the arc rod 203 and the rotating column 207 are connected by the connecting block 205.

[0028] In a preferred embodiment: both the sealing block 6 and the sealing ring 7 are fitted to the outer wall of the ball head 3, and the rubber sleeve 5 is made of polyurethane.

[0029] In the above structure, the gap between the lower fork body 1 and the ball head 3 is sealed by the sealing block 6 and the sealing ring 7, and the rubber sleeve 5 is made of polyurethane to give it better anti-aging properties.

[0030] In a preferred embodiment: the rubber sleeve 5 is adapted to the inner wall of the placement groove 4, and the lower fork arm body 1 is made of aluminum alloy;

[0031] In the above structure, the rubber sleeve 5 is adapted to the inner wall of the placement groove 4, so that the rubber sleeve 5 will not fall off when placed on the inner wall of the placement groove 4. The lower fork body 1 is made of aluminum alloy, which reduces the weight of the lower fork body 1 by more than 30%, reduces the unsprung mass, and reduces the wear rate.

[0032] In a preferred embodiment: there are two of each of the following: limiting rod 202, arc rod 203, fixing rod 204, connecting block 205, placement block 206 and rotating column 207, and the two limiting rods 202, arc rods 203, fixing rods 204, connecting blocks 205, placement blocks 206 and rotating columns 207 are located on top of the fixing block 201.

[0033] In the above structure, the two parts of the lower fork body 1 are connected by two limiting rods 202, an arc rod 203, a fixing rod 204, a connecting block 205, a placement block 206 and a rotating column 207, so that the rigid component 2 of the lower fork body 1 will not fall off during operation.

[0034] Working principle: The rubber sleeve 5 is made of polyurethane, which gives it better wear resistance and aging resistance during use. It also has better high and low temperature resistance. By fixing the sealing block 6 and sealing ring 7 to the lower fork body 1 and making the sealing block 6 and sealing ring 7 fit against the outer wall of the ball joint 3, the intrusion of dust and moisture can be effectively reduced when the ball joint 3 is in use, and the ball joint 3 can be prevented from having steering play due to wear. When the lower fork body 1 is impacted, it will apply pressure to the frame, causing the placement block 206, rotating column 207, connecting block 205 and arc rod 203 to tension the lower fork body 1, ensuring that the lower fork body 1 will not deform when subjected to impact. In addition, the two arc rods 203 are supported and connected by the fixing rod 204 and connecting rod 208, which can prevent the arc rods 203 from loosening after being compressed, thereby improving the rigidity of the lower fork body 1.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
