Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to an automobile control arm capable of preventing deformation. Background Art

[0002] The control arm of a car is used to transmit various forces on the wheels to the car body and limit the movement of the gears. Because the wheels will be subjected to forces in different directions from the ground during driving, and the forces on the four wheels are different, the control arm can ensure that the gears can move along a certain trajectory, thereby maintaining the stability and controllability of the vehicle.

[0003] For example, a Chinese invention patent document with publication number CN107471946B discloses an automobile control arm, comprising a control arm body and a ball head assembly arranged on the control arm body, wherein the control arm body is an arc-shaped curved structure provided with reinforcing ribs; a hole for injecting lubricating grease into the ball head assembly is provided inside the ball head assembly, a lubrication groove structure is provided inside the ball head assembly, and the hole is sealed with the rubber plug.

[0004] In the above document, a hole for filling lubricating grease and related structures are provided at the ball head to facilitate lubrication of the ball head, thereby reducing wear of the ball head and making it easy to replace the ball head assembly.

[0005] However, during the driving of the car, especially when the vehicle passes through complex roads without slowing down, the control arm is subjected to a huge lateral impact force, which may seriously cause the control arm to deform, affecting the control of the wheel and driving stability. In addition, although the above document uses a "C"-shaped first connecting end with a bolt to clamp the ball head to facilitate the replacement of the ball head component, this method will reduce the local structural strength of the first connecting end. The first connecting end must have a certain degree of variability to achieve convenient installation. Utility Model Content

DETAILED DESCRIPTION

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] like Figures 1-8 As shown, this embodiment provides a vehicle control arm for preventing deformation, including a control block 1, which is the main force-bearing component. A sleeve head 101, a hinge head 102 and a socket head 103 extend from the control block 1. The sleeve head 101 and the hinge head 102 are used to connect with the vehicle frame. A cavity layer is opened in the control block 1, and the cavity layer is used to reduce the weight of the component itself. A bottom clamping block 104 is fixed to the bottom of the socket head 103. The bottom clamping block 104 can facilitate docking with the bracket component 3 and increase the structural strength of the control block 1. An outer anti-deformation strip 105 fixed to the bottom of the control block is fixed on the upper portion, and the outer anti-deformation strip 105 can further enhance the ability to resist deformation. An inner anti-deformation part 2 is fixed in the cavity layer, and a bracket component 3 is clamped on the socket 103. The bracket component 3 can be easily assembled and disassembled. An intermediate shell 4 is clamped in the bracket component 3. The intermediate shell 4 is filled in the bracket component 3 and is used to directly contact the spherical connector 5. The spherical connector 5 is rotatably clamped in the intermediate shell 4. The spherical connector 5 needs to have a certain degree of freedom itself, and also needs to extend out to be connected to the external wheel component.

[0027] A rubber sleeve component is provided on the hitch head 101, and a hinge tube is provided on the hinge joint 102, which can facilitate connection and installation with the frame. The internal anti-deformation part 2 is two connected shuttle-shaped blocks, one shuttle-shaped block is directed to conform to the hinge joint 102 and the socket joint 103, and one end of the other shuttle-shaped block points to the hitch head 101, which can facilitate enhancing the structural strength.

[0028] A plug-in slot is provided on the socket head 103, and a plug-in hole is provided in the plug-in slot at one end extending into the cavity layer. The bracket component 3 includes a side support block 301 located on one side of the socket head 103, and a plug-in block 302 plugged into the plug-in slot is fixed on one side of the side support block 301. A hollow rod 303 with one end passing through the plug-in hole is fixed on one side of the plug-in block 302. A fixing screw hole is provided on the socket head 103 above the plug-in slot, and a fixing bolt 106 is threadedly installed in the fixing screw hole. A docking groove is provided on the plug-in block 302 corresponding to the fixing bolt 106, which can facilitate the assembly of the bracket component 3.

[0029] The intermediate shell 4 includes two symmetrical half shells, which are fixedly connected by two symmetrically arranged bracket parts 3 inserted into the socket 103. A conveying through hole connected to the hollow rod 303 is provided on the side support block 301, and a front end hole corresponding to the conveying through hole is provided on the inner wall of the half shell. Horizontal grooves and vertical grooves are provided on the inner wall of the half shell, which can further facilitate the removal of the spherical connector 5.

[0030] A protruding plate is fixed on the side support block 301, and a connecting hole is opened on the protruding plate. The protruding plate is sealed and fixed on the connecting hole by a clamping bolt 304. At the same time, a sealing strip can be provided on the side of the side support block 301 to improve the sealing performance, thereby improving the sealing performance of the bracket component 3. A sealing flange is fixed on the side support block 301, and a rubber sealing cover 6 is provided on the sealing flange. The top of the rubber sealing cover 6 is close to the spherical connector 5, and a supporting ring 305 is fixed on the spherical connector 5. A lower pressure ring 306 is connected to the spherical connector 5 by a threaded manner. The bottom edge of the rubber sealing cover 6 is located between the supporting ring 305 and the lower pressure ring 306, so that the upper part of the spherical connector 5 can be sealed and shielded.

[0031] An injection hole is provided on the outer wall of the hollow rod 303, and a sinking stud 307 is installed on the injection hole. A propulsion spring 308 is provided at one end of the hollow rod 303, and one end of the propulsion spring 308 is connected to a push plunger 309 that is slidably engaged in the hollow rod 303, which makes it easier to maintain the use of the spherical connector 5.

[0032] When in use, if the spherical connector 5 needs to be disassembled, first remove the supporting ring 305, then the rubber sealing cover 6 can be removed, and then the fixing bolts 106 that fix the side support block 301 can be loosened. At this time, the bracket component 3 can be pulled out, and then the clamping bolts 304 on the protruding plate can be loosened to separate the side support block 301, and then the intermediate shell 4 and the spherical connector 5 can be taken out. When it is necessary to inject grease, remove the sinking studs 307 on the two hollow rods 303, and then inject it on one side. The grease enters the intermediate shell 4 through the hollow rod 303 and flows between the horizontal groove and the vertical groove. It should be noted that the bottoms of the vertical grooves are not connected to each other. The groove is not connected near the side support block 301, which can limit the lubricating grease from circulating once at the bottom of the spherical connector 5, entering the hollow rod 303 on the other side, and then flowing out from the injection hole on the other side. After the injection is completed or the lubricating grease is replaced, it is necessary to use a sinking stud 307 to block the injection hole. When the vehicle is driving, the lubricating grease is squeezed, and the push plunger 309 can push the propulsion spring 308 when it receives pressure, thereby storing part of the grease, and the storage amount can be adjusted according to actual needs. Specifically, a hole is opened at one end of the hollow rod 303 to prevent the push plunger 309 from getting stuck or a rubber sealing layer is set after the hole is opened at one end of the hollow rod 303.
