Description

Technical Field

[0001] The utility model relates to the technical field of automobile control arms, in particular to a high-toughness automobile control arm. Background Art

[0002] Automobile control arms are part of the automobile suspension system and are usually made of metal. They connect the wheels and the body and play a role in supporting and controlling the movement of the wheels. Control arms are usually connected to shock absorbers, springs and wheel suspensions. The position and structure of the control arms can affect the vehicle's suspension performance, handling and driving stability. Different types of vehicles will use control arms of different designs and forms to suit their specific suspension needs and performance requirements.

[0003] At present, the existing device (such as patent number: CN219667902U) discloses a vehicle control arm, which is provided with a clamping block so that when the movable plate is pressed upward, the elastic ball is squeezed, and the movable rods on both sides drive the clamping block to clamp the connecting sleeve and fix it, thereby avoiding damage to the threads on the connection of the control arm and reducing economic losses;

[0004] However, in the process of implementing the above technical solution, it was found that there are at least the following technical problems: since the automobile control arm is used to connect the wheel bracket and the front subframe, when the vehicle goes over a bumpy or pothole-prone road section, the threaded bearing pressure at the connection of the control arm will be relatively large. Since the device is overall arc-shaped and has connection points on both sides, it is easy for the automobile control arm to suffer from metal fatigue when subjected to more frequent and greater pressure, thereby causing certain damage to the internal structure of the automobile control arm, affecting its use, and its practicality needs to be improved.

[0026] Example

[0027] like Figure 1-Figure 5 As shown, the technical solution in the embodiment of the present application effectively solves the technical problem of insufficient practicality of the existing device, and the overall idea is as follows:

[0028] In view of the problems existing in the prior art, the utility model provides a high-toughness automobile control arm, comprising an automobile control arm body 11, wherein a first connecting pin groove 12 and a second connecting pin groove 13 are respectively arranged inside the automobile control arm body 11, and the two second connecting pin grooves 13 are both located on both sides of the first connecting pin groove 12, and the automobile control arm body 11 is arc-shaped as a whole;

[0029] The upper end and the lower end of the vehicle control arm body 11 are symmetrically fixed with a reinforcement mechanism;

[0030] The reinforcement mechanism includes a fixed column 14, each of which is provided with a first threaded connection point 15 on the circumferential surface of the fixed column 14, and each of which is provided with a circular piece 16 on the circumferential surface of the fixed column 14, and each of which is provided with a through groove 17 inside. Each through groove 17 is located on the circumferential surface of the fixed column 14, and the inner diameter of each through groove 17 is greater than the diameter of the fixed column 14. The reinforcement mechanism also includes a second threaded connection point 18, a connecting rod 19, a first threaded connection column 21, a second threaded connection column 22 and a reinforcement rod 25, each of which is located below the first threaded connection point 15, each of which is opened inside the circular piece 16, and each of which is located inside the circular piece 19. 16 is fixedly installed on the circumferential surface, and each first threaded connecting column 21 is located inside the second threaded connecting point 18 and is threadedly installed. By arranging connecting rods 19 at the upper and lower ends of the automobile control arm body 11, and arranging reinforcing rods 25 between each group of connecting rods 19, and because the overall structure of the circular member 16, the connecting rods 19 and the reinforcing rods 25 is a triangle in shape, the triangle has stability, and the ceramic metal of the reinforcing rods 25 itself has good toughness, and is symmetrically arranged on one side of the automobile control arm body 11 near the two side ends, it can effectively suppress excessive deformation of the automobile control arm during the force process, maintain the stability of its shape and structure, and thereby improve the overall toughness and performance.

[0031] The circumferential surface of each second threaded connection column 22 is threadedly installed at the first threaded connection point 15, and each second threaded connection column 22 is fixedly installed with the first threaded connection column 21. The upper end of the second threaded connection column 22 above the automobile control arm body 11 and the lower end of the second threaded connection column 22 below the automobile control arm body 11 are fixedly installed with a circular screw head 23, and a cross screw groove 24 is opened inside the circular screw head 23. The two reinforcement rods 25 are fixedly installed between the connecting rods 19. The two reinforcement rods 25 are both arc-shaped, and the two reinforcement rods 25 are symmetrically arranged with the automobile control arm body 11. The material of the two reinforcement rods 25 is ceramic metal, each circular part 16, the connecting rod 19, and the reinforcement rod 25 are a whole, each first threaded connection column 21, the second threaded connection column 22 and the circular screw head 23 are a whole, and each first threaded connection column 21 and the second threaded connection column 1 The connecting column 22 is stepped as a whole, and each first threaded connecting column 21 and the second threaded connecting column 22 is stepped as a whole.

In addition, by making the first threaded connecting column 21 and the second threaded connecting column 22 and the first threaded connecting column 21 and the second threaded connecting column 22 as a whole stepped, the first threaded connecting column 21 and the second threaded connecting column 22 can be fixed by double threads, thereby ensuring the firmness of the fixing of the circular part 16, the connecting rod 19 and the reinforcing rod 25.

[0032] Working principle:

[0033] The first step is to pick up the circular piece 16, the connecting rod 19 and the reinforcing rod 25 as a whole and place them between a group of first threaded connection points 15 above the automobile control arm body 11. Then the staff can pre-fix the circular screw head 23, the second threaded connection column 22 and the first threaded connection column 21 on the surface of the second threaded connection point 18 and the first threaded connection point 15. Then the staff can use a cross screwdriver to insert it into the cross screw groove 24 and rotate it, so that the cross screw groove 24 generates a radial force to drive the first threaded connection column 21 and the second threaded connection column 22 to connect with the second threaded connection point 18 and the first threaded connection point 15 respectively. After the connection is completed, the automobile control arm body 11 can be turned over and the above steps can be repeated to install the circular piece 16, the connecting rod 19 and the reinforcing rod 25 on another group of fixing columns 14.

[0034] The second step is to set connecting rods 19 at the upper and lower ends of the automobile control arm body 11, and set reinforcing rods 25 between each group of connecting rods 19 during use. Since the overall structure of the circular part 16, the connecting rods 19 and the reinforcing rods 25 is a triangle in shape, the triangle has stability, and the reinforcing rods 25 themselves have good toughness due to their ceramic metal. They are symmetrically set on one side of the automobile control arm body 11 close to the ends on both sides, which can effectively suppress excessive deformation of the automobile control arm during the force-bearing process.

[0035] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
