Description

[0002] With the rapid development of the automobile industry, consumers have higher and higher requirements for the controllability, comfort and safety of automobiles. Traditional suspension systems, such as MacPherson suspension and connecting rod strut suspension, meet these requirements to some extent, but their performance still needs to be improved when facing complex road conditions and high-speed driving.

[0003] Multi-connecting rod suspension systems, as a kind of complex and advanced suspension system, have gradually become the first choice for medium and high-end vehicles due to their excellent controllability, comfort and stability.

[0004] The connecting rods in the traditional multi-connecting rod suspension system are connected to the universal structure, and the universal structure is then fixed at the desired position by bolts and nuts.

[0005] In the multi-connecting rod mechanism mounting device disclosed in Chinese patent (authorized publication number CN212899588U), "the other end of the crank 2 is connected through the second rotating shaft 9 and the connecting rod assembly 3";

[0006] In the multi-connecting rod type automobile rear suspension system disclosed in Chinese patent (authorized publication number CN105620215B), "the connecting rod 6 extends in the front-rear direction, and the two ends of the connecting rod 6 extend with mounting heads 61 and 62, which are spherical structures. The connecting piece 8 is a cross connecting rod, and the axis of the cross connecting rod is parallel to the axis of the rear wheel hub 1. The cooperation of the mounting heads 61 and 62, the reduced diameter rod 81 and the mounting rod 32 can realize the rotary mounting of the two ends of the connecting rod 6".

[0007] However, they all have certain drawbacks: during long-term use, the bolts and nuts are prone to pre-tightening force decay due to continuous vehicle vibration, resulting in gap loosening at the connection part, which in turn causes problems such as positioning deviation of the universal structure and abnormal wear at the ball head connection, seriously affecting the geometric accuracy and dynamic stability of the suspension system, and even causing safety hazards such as failure of the connecting rod assembly.
