As people pay more attention to automobile fuel consumption, automobile lightweighting has become a trend in the development of the automobile industry. In order to achieve automobile lightweighting, the connection between the frame and the wheel is generally achieved through the swing arm.

[0003] The function of the swing arm is to guide and support the suspension, which can effectively improve the stability of the car steering wheel. Most existing automobile swing arms are fixedly connected between the ball head assembly and the swing arm during production, and the camber angle and wheelbase of the front wheel cannot be adjusted. In order to solve the problem of being unable to adjust the angle between the ball head assembly and the swing arm, a variety of technical means have been adopted, such as the adjustable automobile swing arm assembly in the prior art, which includes a swing arm body, a ball head assembly, an adjustment gasket and a positioning component. One end of the swing arm body is provided with a mounting groove, and the ball head assembly is arranged in the mounting groove. A mounting plate is provided on the ball head assembly, and the mounting plate is adapted to be plugged in the mounting groove. The utility model arranges an adjustment gasket with an inclined surface between the ball head assembly and the swing arm, and fits the inclined surface with the inner wall of the mounting plate or the mounting groove, so that the ball head assembly is tilted at a corresponding angle to achieve the adjustment of the camber angle.

[0004] However, the prior art adjusts the angle of the ball head assembly by setting adjustment pads of different heights, and multiple disassembly is required to debug the angle, which increases the labor cost of workers and easily causes the loss of the adjustment pads after long-term use. Utility Model Content

[0005] The utility model provides an automobile swing arm assembly to solve the problem that when adjusting the rotation angle of the automobile swing arm by means of a gasket in the above-mentioned prior art solution, the gasket needs to be removed multiple times to change the angle, and the adjustment gasket is easily lost during use. The automobile swing arm in the solution does not need to use a gasket to adjust the rotation angle of the automobile swing arm, and the gasket does not need to be removed during adjustment, and the loss of the gasket can also be avoided.

[0006] The technical solution adopted by the utility model is: an automobile swing arm assembly, including a swing arm body, a connecting assembly, a ball head assembly and an adjusting assembly, wherein the connecting assembly is connected to one end of the swing arm body, and the ball head assembly is connected to the other end of the swing arm body through the adjusting assembly.

[0025] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0026] Example 1

[0027] like Figure 1-Figure 3 The figure shows an embodiment 1 of an automobile swing arm assembly, which includes a swing arm body 1, a connecting component, a ball head component and an adjusting component 3. The connecting component is connected to one end of the swing arm body 1, and the ball head component is connected to the other end of the swing arm body 1 through the adjusting component 3. The adjusting component 3 includes an adjusting rod, a fixing plate 301 fixedly connected to the swing arm body 1, and an adjusting plate 302 rotatably connected to the fixing plate 301. The ball head component is fixedly connected to the adjusting plate 302, and a mounting groove is provided at one end of the side of the adjusting plate 302 away from the fixing plate 301, and a fixing block 304 is slidably connected in the mounting groove. The adjusting rod includes a first rod body 305 and a second rod body 306. The first rod body 305 is sleeved on the second rod body 306 and the first rod body 305 is threadedly connected to the second rod body 306. The first rod body 305 is rotatably connected to the mounting seat on the fixing plate 301, and the second rod body 306 is hinged to the fixing block 304.

[0028] The working principle or working process of this embodiment is as follows: the first rod body 305 and the second rod body 306 in the adjustment rod are threadedly connected, so when the first rod body 305 and the second rod body 306 rotate relative to each other, the length of the adjustment rod will change. The first rod body 305 is rotationally connected to the mounting seat on the fixed plate 301, and the first rod body 305 cannot slide on the fixed plate 301; the second rod body 306 is hinged to the fixed block 304, and the second rod body 306 cannot slide on the fixed block 304. When it is necessary to increase the angle between the ball head assembly and the swing arm body 1, the first rod body 305 is rotated forward to increase the length of the adjustment rod. When the length of the adjusting rod extending into the space between the fixing block 304 and the fixing plate 301 increases, since the fixing block 304 is in the installation groove on the adjusting plate 302, the fixing block 304 will slide in the installation groove toward the end away from the fixing plate 301 and the second rod body 306 will rotate on the fixing block 304, so that the angle of the triangle formed by the adjusting rod, the fixing plate 301 and the adjusting plate 302 increases as the length of the adjusting rod increases, thereby achieving the purpose of increasing the angle between the ball head and the swing arm body 1. When it is necessary to reduce the angle between the ball head assembly and the swing arm body 1, the first rod body 305 is rotated in the opposite direction, the length of the adjusting rod is reduced, the fixing block 304 will slide in the installation groove toward the end close to the fixing plate 301 and the second rod body 306 will rotate in the opposite direction on the fixing block 304. As the length of the adjusting rod decreases, the angle between the adjusting plate 302 and the fixing plate 301 in the triangle formed by the adjusting rod, becomes smaller, thereby achieving the purpose of reducing the angle between the ball head and the swing arm body 1.

[0029] Beneficial effects of this embodiment: When the angle of the ball head assembly needs to be adjusted, the length of the adjustment rod is changed by rotating the first rod body 305, and the angle between the ball head and the swing arm body 1 is adjusted by changing the length of the adjustment rod, thereby effectively adjusting the angle of the ball head assembly without the need for multiple adjustments, making the swing arm as a whole more practical.
