Embodiment 1
[0086] This embodiment provides a connection mechanism between the control arm and the sub-frame, such as Figure 2 ~ Figure 6As shown, the connection mechanism between the control arm and the sub-frame includes a shifting structure 1 , a control arm bushing 2 and a force rod 3 . Specifically, the opening structure 1 is arranged on the sub-frame 6, and the opening structure 1 includes a pair of opposite opening part plates 11; , the pair of waist-shaped holes 111 are respectively located on the two shifting part plates 11; the control arm bushing 2 is arranged at the front end of the control arm 7 and installed between the two shifting part plates 11; the force rod 3 runs through the control The arm bushing 2 and both ends are connected in the waist-shaped hole 111 , and when the vehicle is subjected to a biased collision, the force-receiving rod 3 moves along the extension direction of the waist-shaped hole 111 .
[0087] According to the connection mechanism between the con...

The invention discloses a connecting mechanism for a control arm and an auxiliary frame. The connecting mechanism comprises a gear opening structure, a control arm bush and a stress rod. The gear opening structure is arranged on the auxiliary frame and comprises a pair of opening part plates; the gear opening structure is provided with a pair of kidney-shaped holes opposite to each other in a mirror image mode, and the kidney-shaped holes are located in the two opening part plates respectively. The control arm bushing is arranged at the front end of the control arm and is mounted between the two opening part plates; the stress rod penetrates through the control arm lining, the two ends of the stress rod are connected into the kidney-shaped holes, and when the vehicle is subjected to offset collision, the stress rod moves in the extending direction of the kidney-shaped holes. And the anti-skid surface of the elastic anti-skid axial limiting piece is tightly attached to the outer side surface of the open gear part plate, so that the friction force borne by the stress rod in the extension direction of the waist-shaped hole is enlarged. When a vehicle is subjected to offset collision, the stress rod slides along the extension direction of the waist-shaped hole in a friction manner, so that collision energy can be absorbed and buffered, the problem that a wheel edge part is completely out of control due to direct separation of the control arm and the auxiliary frame is avoided, and the passive safety of collision is improved.
Description
technical field [0001] The invention relates to the field of automobile chassis connection, in particular to a connection mechanism between a control arm and a sub-frame. Background technique [0002] The subframe can be regarded as the skeleton of the front and rear axles, and is an integral part of the front and rear axles. The function of the subframe is to block vibration and noise, preventing it from directly entering the compartment. This suspension assembly with subframe, in addition to bringing various conveniences and advantages in design and installation, the most important thing is the improvement of its comfort and suspension rigidity. Some spare parts of the suspension are assembled to the subframe to form an assembly part and then connected to the body, which brings convenience to the assembly. The control arm of the suspension is generally connected to the subframe through the control arm bushing at the front end of the control arm. [0003] At present, the...
