[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0021] EMBODIMENT

[0022] With reference to the drawings Figs. 1-2 As shown in the drawings, a camber adjusting device 1 is used to connect a lower swing arm and a subframe; comprising: a mounting pad 11, a screw rod 12, an internally threaded rod pad 14, and no less than one locking nut 13, the mounting pad 11 is provided with two connecting bolts 15 at one end, so as to be connected to the lower swing arm through the two connecting bolts; the mounting pad 11 is provided with the screw rod 12 at the other end, the screw rod 12 is threadedly connected to one end of the internally threaded rod pad 14, and the other end of the internally threaded rod pad 14 is fixedly connected to the subframe; one of the locking nuts 13 is sleeved on the screw rod 12 and located between the mounting pad 11 and the internally threaded rod pad 14, and abuts against the internally threaded rod pad 14, so as to limit the screw rod after adjustment, and further fix the distance between the lower swing arm and the subframe.

[0023] The mounting pad 11 is in the shape of a “U”, and the upper end of the “U” shaped mounting pad 11 is provided with two connecting internal threads matched with the connecting bolts, so as to be connected to the lower swing arm 2 through the plate spring pin 21 of the lower swing arm 2; the “U” shaped mounting pad 11 is internally provided with a mounting pad hole matched with the screw rod 12, and the screw rod 12 is threadedly connected to the internally threaded rod pad 14 through the mounting pad hole, in this embodiment, the internally threaded rod pad 14 is arranged in the subframe and fixedly connected to the subframe; it can be integrally formed with the control arm, or separately arranged in the control arm. The no less than one locking nut 13 is sleeved on the screw rod 12 and located between the mounting pad 11 and the internally threaded rod pad 14, so as to adjust and fix the length of the screw rod 12 between the mounting pad 11 and the internally threaded rod pad 14, and further adjust and fix the distance between the lower swing arm and the subframe.

[0024] When only one locking nut 13 is arranged, the locking nut 13 is arranged on the side close to the internally threaded rod pad 14, so as to ensure that the connection between the screw rod 12 and the internally threaded rod pad 14 is loose during driving. When two locking nuts 13 are arranged, the other locking nut 13 is arranged on the side close to the mounting pad 11, so as to ensure that the connection between the screw rod 12 and the mounting pad 11 is loose during driving, and further ensure the connection position; the rotation of the screw rod 12 can also be controlled by operating the locking nut.

[0025] In one specific embodiment, a wheel camber adjustment device includes a mounting pad 11 that is fixedly connected to the lower control arm of the crossarm via a threaded connection; a screw 12 passes through the mounting pad hole of the mounting pad 11, with one end of the screw 12 being cylindrical and larger in diameter than the mounting pad hole, and the other end being a screw rod. It can be fixed to the mounting pad 11 by welding or by a threaded connection. When the connection is made by thread, at least two locking nuts 13 are required to ensure the connection between the screw 12 and the mounting pad 11; the locking nuts 13 are also adjustment nuts. After the length of the device is adjusted, tightening the locking nuts completes the camber adjustment; one end of the internally threaded rod pad 14 is welded to the subframe and fixed to the subframe, and the other end has a hole with internal threads, which is connected to the screw 12 via a threaded pair.

[0026] During adjustment, calculate the required length of the lower control arm using the four-wheel alignment parameters. If the camber angle needs to be increased, turn screw 12 clockwise. Screw 12 will rotate the lower control arm towards the longitudinal plane, increasing the camber angle. The movement distance is the calculated length. Then check if the camber angle on the four-wheel alignment instrument meets the requirements. If it does, tighten the lock nut 13; if not, continue adjusting. It is worth noting that there are usually two adjustment devices installed on the left and right sides of the lower control arm; therefore, both adjustment devices are usually used together during adjustment.

[0027] This device adds a screw to the crossarm, and the position of the crossarm is adjusted by adjusting the length of the screw so that the camber angle of the wheel meets the design requirements.

[0028] For higher adjustment precision and less effort, a motor-driven lead screw can be used instead of a screw, and the motor drives the lower arm to move. This allows for automatic adjustment of the camber angle through electric control when the wheel bounces up and down.

[0029] In another specific embodiment, in conjunction with the appendix Figs. 1-2 As shown, a commercial vehicle includes a wheel camber adjustment device 1, a lower control arm 2, and a subframe 3 as described above, to adjust the distance between the lower control arm and the subframe, as well as the angle of the lower control arm. Preferably, the subframe 3 has a slot 31 at its end for mounting the wheel camber adjustment device. A twisting device, such as a wrench, is inserted into the side of the slot to rotate the screw 12, thereby causing the lower control arm, mounting pad 11, and screw 12 to rotate relative to the subframe. The slot at the end of the subframe provides rotation for the wheel camber adjustment device, connecting the lower control arm and the subframe to adjust the wheel camber angle. This method offers advantages such as high adjustment efficiency, low cost, and high success rate.

[0030] Although the present application has been described with reference to the explanatory embodiments thereof, the above-described embodiments are merely the preferred embodiments of the present application, and the embodiments of the present application are not limited to the above-described embodiments, and it should be understood that many other modifications and embodiments can be designed by those skilled in the art, and these modifications and embodiments will fall within the scope and spirit of the principles disclosed in the present application.
