Description

Technical Field

[0001] The utility model belongs to the field of control arms, in particular to a heat dissipation type control arm. Background Art

[0002] The control arm is a critical safety part of automobile options. One end of the ball pin is connected to the steering knuckle, and the other end of the bushing is connected to the subframe. It plays the role of controlling the positioning parameters of the suspension during movement and transmitting loads.

[0003] When the control arm is in use, the ball joint and the ball rod rotate relative to each other, which generates friction and heat. At this time, the heat will generally only be discharged from the outer periphery of the ball joint. However, when the rotation frequency is faster, a large amount of heat will be generated in a short period of time and cannot be discharged in time, which will cause the control arm to wear more severely and easily deform.

[0016] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.

[0017] As shown in FIG1-3, a heat dissipation control arm includes a control arm body 10, and a ball joint interface 11 is fixed on the control arm body 10, characterized in that: a heat dissipation component is installed on the outer peripheral side of the control arm body 10, and the heat dissipation component is installed on one side of the ball joint interface 11;

[0018] The heat dissipation assembly includes a heat conductive block 13 installed in the control arm body 10 and a heat conductive ring 12 installed in the ball head interface 11. A notch is provided on the outer peripheral side of the control arm body 10, an annular groove is provided in the ball head interface 11, the heat conductive ring 12 is located in the annular groove, the heat conductive block 13 is fixedly installed in the notch, the heat conductive block 13 and the heat conductive ring 12 are connected together, at least two heat dissipation rods 17 and a rack 16 are provided in the heat conductive block 13, a gear 18 is fixed on the heat dissipation rod 17, the gear 18 is rotatably installed on the inner wall of the heat conductive block 13, the gear 18 is meshed with the rack 16, and a memory metal 19 is fixed between the rack 16 and the inner wall of the heat conductive block 13.

[0019] At least two heat dissipation holes 15 are provided on one end surface of the heat conductive block 13, and a sliding cavity 14 is also provided in the heat conductive block 13. One end of the memory metal 19 is fixed on the rack 16, and the other end is fixed on the inner wall of the sliding cavity 14. The heat dissipation hole 15 is connected with the sliding cavity 14, wherein the heat dissipation rod 17 and the gear 18 are located in the heat dissipation hole 15, the gear 18 is installed on the inner wall of the heat dissipation hole 15 through a rotating shaft, and the rack 16 is slidably installed in the sliding cavity 14.

[0020] When in use, the control arm body 10 can be installed. During use, relative rotation occurs between the ball head interface 11 and the ball head rod, thereby generating frictional heat. At this time, the heat is generally discharged from the outer periphery of the ball head interface 11, but when the rotation frequency is faster, a large amount of heat will be generated in a short time. At this time, the heat can be absorbed by the heat-conducting ring 12 and the heat-conducting block 13 with better thermal conductivity, and then dissipated. When the heat is high, the memory metal 19 will shrink due to the heat, and the rack 16 will be pulled to move to the side close to the heat-conducting ring 12. The rack 16 can drive the gear 18 to rotate, so that the heat dissipation rod 17 is vertically erected with the heat-conducting block 13, increasing the contact surface between the heat dissipation component and the air, thereby accelerating its heat dissipation. When the heat discharge temperature in the ball head interface 11 drops, the memory metal 19 will return to its initial state, that is, drive the rack 16 so that the gear 18 drives the heat dissipation rod 17 to enter the heat dissipation hole 15, thereby reducing the space occupied by it.

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
