Description

Technical Field

[0001] This utility model relates to the field of high-strength automotive chassis control arm technology, specifically a high-strength automotive chassis control arm. Background Technology

[0002] The core function of the chassis control arm is to connect the frame and the wheels, and to precisely control the movement trajectory of the wheels while the vehicle is in motion.

[0003] For example, a high-strength adjustable upper control arm for automotive chassis, with announcement number "CN212579546U", features targeted axial reinforcing ribs and several longitudinal reinforcing ribs, effectively improving the strength and rigidity of the upper control arm. The number of longitudinal reinforcing ribs can be set and installed as needed, offering high flexibility in adjustment. Moreover, the reinforcing ribs are made of spring steel, which has excellent shock absorption and buffering effects. The control arm has high overall application quality and a long service life. However, in the use of automotive chassis control arms, the reinforcing rib assembly adopts a "detachable interference fit". Although this facilitates later adjustments, the stability of the interference fit depends on the initial assembly accuracy of the parts and the elasticity of the materials. Over long-term use, the high-frequency vibrations generated by vehicle driving will cause the interference fit surface to gradually wear down, increasing the fit clearance. This may lead to loosening and displacement of the longitudinal reinforcing ribs, resulting in collisions between parts. Consequently, the strength of the automotive chassis control arm gradually decreases, causing vibration and noise in the automotive chassis control arm. Utility Model Content

[0004] The purpose of this invention is to solve the problem of the gradual decrease in strength of the automotive chassis control arm, which leads to vibration and noise in the automotive chassis control arm, and to propose a high-strength automotive chassis control arm.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A high-strength automotive chassis control arm is designed, including a first connecting shaft, an automotive control arm fixedly connected to the left side of the first connecting shaft, a processing structure connected to the outer wall of the automotive control arm, a second connecting shaft fixedly connected to the left side of the automotive control arm, and protective structures connected to the outer walls of the first and second connecting shafts respectively.

[0006] This feature: The vehicle control arm, as the core "force transmission and guidance element" of the chassis suspension system, works around three core functions: "force transmission", "motion trajectory control" and "cooperative damping". Through its own structural design and cooperation with other components of the suspension system, it ensures the stability, handling and comfort of the vehicle when driving.

[0007] Preferably, the reinforcement structure includes a bracket and a cross plate. The inner walls of the brackets are inserted into the outer wall of the vehicle control arm. The outer walls of the brackets on the left and right sides are respectively fixed to the left and right ends of the cross plate. A straight plate is fixed to the outer wall of the cross plate. Square plates are fixed to the upper and lower sides of the brackets. A first screw is inserted into the inner wall of the square plate. A nut is threaded onto the front of the outer wall of the first screw.

[0008] This setting: When the nut is subjected to force, it rotates back and forth through the outer wall of the first screw. The outer wall of the nut can then abut against the outer wall of the front square plate, thus fixing the first screw and preventing it from loosening or coming off.

[0009] Preferably, the inner sides of the two horizontal plates are respectively attached to the front and rear sides of the vehicle control arm.

[0010] This feature involves the outer wall of the horizontal plate fitting snugly against the outer wall of the vehicle control arm, increasing the thickness and strength of the vehicle control arm while significantly reducing its weight through its own elasticity.

[0011] Preferably, the outer walls of the two straight plates are respectively inserted into the slots on the front and rear sides of the vehicle control arm.

[0012] This setting: After the outer wall of the straight plate is inserted into the groove of the outer wall of the car control arm, it restricts the horizontal plate and prevents the horizontal plate from deforming vertically.

[0013] Preferably, the protective structure includes an arc plate and a round pad. The inner walls of the two arc plates are respectively inserted into the outer walls of the first connecting shaft and the second connecting shaft. The upper and lower sides of the arc plates are respectively fixed to the outer walls of the two round pads. The upper and lower sides of the arc plates are respectively threaded with a second screw.

[0014] This setting: The round pad is a metal washer that can press against the end of the second screw to increase friction and prevent the second screw from loosening when subjected to vibration.

[0015] Preferably, the inner side of the outer wall of the second screw is threaded to the outer wall of the vehicle control arm.

[0016] This setting: After the inner side of the outer wall of the second screw is connected to the round thread of the outer wall of the car control arm, the arc plate and the connecting shaft are fixed to prevent the arc plate from detaching from the outer wall of the connecting shaft.

[0017] Preferably, the inner wall of the vehicle control arm is fixedly connected to an inner core.

[0018] This feature: The inner core, made of its own carbon fiber material, ensures the original strength of the car arm while greatly reducing its weight.

[0019] The present invention proposes a high-strength automotive chassis control arm, which has the following advantages: Multiple brackets in the reinforcement structure are inserted into the front and rear sides of the automotive control arm until the outer walls of multiple square plates are in contact. At this point, the outer walls of two horizontal plates are in contact with the front and rear sides of the automotive control arm, respectively. Simultaneously, the straight plates on the outer walls of the horizontal plates are inserted into the grooves on the outer walls of the automotive control arm. Then, a first screw passes from back to front through the two in contact square plates until the rear rib of the first pull rod is in contact with the outer wall of the rear square plate. Subsequently, the nut rotates backward through the outer wall of the first screw, causing the outer wall of the nut to abut against the outer wall of the front square plate, thus fixing the square plates and brackets, and fixing the horizontal plates to the automotive control arm. This changes the original reinforcement method, preventing loosening and detachment due to vibration, preventing a gradual decrease in the strength of the automotive chassis control arm, and avoiding vibration noise from the automotive chassis control arm.

[0022] The present invention will be further described below with reference to the accompanying drawings: Please see Figure 1-5In this embodiment, a high-strength automotive chassis control arm includes a first connecting shaft 1, an automotive control arm 4 fixedly connected to the left side of the first connecting shaft 1, a processing structure 2 connected to the outer wall of the automotive control arm 4, and a second connecting shaft 5 fixedly connected to the left side of the automotive control arm 4. The automotive control arm 4, as the core "force transmission and guidance element" of the chassis suspension system, operates around three core functions: "force transmission," "motion trajectory control," and "cooperative shock absorption." Through its own structural design and cooperation with other components of the suspension system, it ensures the stability, handling, and comfort of the vehicle during driving. Protective structures 3 are respectively connected to the outer walls of the first connecting shaft 1 and the second connecting shaft 5.

[0023] The reinforcement structure 2 includes brackets 201 and horizontal plates 202. The inner walls of multiple brackets 201 are inserted into the outer wall of the vehicle control arm 4. After the brackets 201 are inserted into the outer wall of the vehicle control arm 4, they form a wrap-around installation of the vehicle control arm 4. The outer walls of the brackets 201 on the left and right sides are fixed to the left and right ends of the horizontal plate 202, respectively. A straight plate 203 is fixed to the outer wall of the horizontal plate 202. Square plates 204 are fixed to the upper and lower sides of the brackets 201, respectively. A first screw 205 is inserted into the inner wall of the square plate 204. The rear protrusion of the first screw 205 fits against the outer wall of the rear square plate 204. A nut 206 is threaded to the front of the outer wall. The nut 206 rotates back and forth through the outer wall of the first screw 205 under force. The inner sides of the two horizontal plates 202 are respectively attached to the front and rear sides of the car control arm 4. The outer wall of the horizontal plate 202 is attached to the outer wall of the car control arm 4, which increases the thickness of the car control arm 4 and improves its strength. At the same time, the material itself is elastic and greatly reduces the weight. The outer walls of the two straight plates 203 are respectively inserted into the slots on the front and rear sides of the car control arm 4. After the outer walls of the straight plates 203 are inserted into the slots on the outer wall of the car control arm 4, they restrict the horizontal plates 202 and prevent the horizontal plates 202 from deforming vertically. Multiple brackets 201 in the reinforcement structure 2 are inserted into the front and rear sides of the vehicle control arm 4 until the outer walls of multiple square plates 204 are in contact. At this time, the outer walls of two horizontal plates 202 are in contact with the front and rear sides of the vehicle control arm 4, and the straight plates 203 on the outer walls of the horizontal plates 202 are inserted into the grooves on the outer walls of the vehicle control arm 4. Then, the first screw 205 passes through the two in contact square plates 204 from back to front until the rear rib of the first pull rod 205 is in contact with the outer wall of the rear square plate 204. Then, the nut 206 rotates backward through the outer wall of the first screw 205, so that the outer wall of the nut 206 abuts against the outer wall of the front square plate 204, thus completing the fixation of the square plate 204 and the bracket 201, and fixing the horizontal plate 202 to the vehicle control arm 4. This changes the original reinforcement method, prevents loosening and detachment due to vibration, prevents the strength of the vehicle chassis control arm from gradually decreasing, and prevents the vehicle chassis control arm from generating vibration noise.

[0024] The protective structure 3 includes an arc plate 301 and a round pad 302. The inner walls of the two arc plates 301 are respectively inserted into the outer walls of the first connecting shaft 1 and the second connecting shaft 5. The upper and lower sides of the arc plate 301 are respectively fixed to the outer walls of the two round pads 302. The round pads 302 are metal washers that can abut against the end of the second screw 303 to increase friction and prevent the second screw 303 from loosening when subjected to vibration, thus ensuring the stable installation of the second screw 303. The upper and lower sides of the arc plate 301 are respectively threaded with the second screw 303. The inner side of the outer wall of the second screw 303 is threaded to the outer wall of the car control arm 4. The inner wall of the car control arm 4 is fixed with an inner core 6. The inner core 6 is made of carbon fiber, which ensures the original strength of the car arm while greatly reducing the weight.

[0025] Working principle: Automotive chassis control arm assembly: Multiple brackets 201 are inserted into the front and rear sides of the vehicle control arm 4 until the outer walls of multiple square plates 204 are in contact. At this time, the outer walls of two horizontal plates 202 are in contact with the front and rear sides of the vehicle control arm 4, and the straight plate 203 of the outer wall of the horizontal plate 202 is inserted into the groove of the outer wall of the vehicle control arm 4. Then, the first screw 205 passes through the two in contact square plates 204 from back to front until the rear rib of the first pull rod 205 is in contact with the outer wall of the rear square plate 204. Then, the nut 206 rotates backward through the outer wall of the first screw 205, so that the outer wall of the nut 206 abuts against the outer wall of the front square plate 204, thus completing the fixation of the square plate 204 and the bracket 201, and fixing the horizontal plate 202 to the vehicle control arm 4. This changes the original reinforcement method, prevents loosening and detachment due to vibration, and improves the strength of the vehicle control arm 4.

[0026] Next, the inner walls of the two arc plates 301 are respectively inserted into the outer walls of the first connecting shaft 1 and the second connecting shaft 5. At this time, the outer wall rib of the arc plate 301 will fit against the outer wall of the vehicle control arm 4. Then, the second screw 303 passes through the arc plate 301 and is threaded into the outer wall of the vehicle control arm 4 until the outer wall rib of the second screw 303 abuts against the outer wall of the round washer 302, thereby reinforcing the second screw 303 and completing the installation of the arc plate 301. The arc plate 301 reinforces the connection between the first connecting shaft 1, the second connecting shaft 5 and the vehicle control arm 4.

[0027] The inner core 6 of the inner wall of the car control arm 4 is made of carbon fiber, which ensures the original strength of the car arm while greatly reducing its weight. Align the first connecting shaft 1 on the right side of the control arm with the frame connecting seat, and then insert the connecting rod at the top of the first connecting shaft 1 into the frame connecting seat. Then, the collar is threaded onto the outer wall of the connecting rod from top to bottom. Next, align the second connecting shaft 5 at the other end of the control arm with the connecting hole of the wheel hub bearing seat, insert the ball head bolt, and tighten the bolt by hand to keep the control arm from being obviously skewed. Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
