Rear suspension pull rod structure for connecting power assembly with front sub frame

Abstract

The invention discloses a rear suspension pull rod structure for connecting a power assembly with a front sub frame. The rear suspension pull rod structure for connecting the power assembly with the front sub frame aims at solving the problem that an existing rear suspension pull rod cannot adapt to the increasingly high torque of an automobile acting assembly. The rear suspension pull rod structure for connecting the power assembly with the front sub frame comprises the power assembly, the front sub frame and a connecting bracket which is connected between the power assembly and the front subframe; the connecting bracket comprises a first connecting bracket and a second connecting bracket; the first connecting bracket comprises a first rear suspension upper body and a first rear suspension lower body; the second connecting bracket comprises a second rear suspension upper body and a second rear suspension lower body; the first rear suspension upper body and the second rear suspensionupper body are connected to the power assembly; the first rear suspension lower body and the second rear suspension lower body are fixedly connected to the front sub frame; the first rear suspension upper body is hinged and connected to the first rear suspension lower body; and the second rear suspension upper body is hinged and connected to the second rear suspension lower body. The displacementof the power assembly is avoided, the jumping of the power assembly is avoided, and therefore, noises and vibrations are reduced, and better taking feeling is brought.

Description

technical field [0001] This invention relates to automotive body components, and more specifically, it relates to a rear suspension tie-rod structure that connects the powertrain to the front subframe. Background technique [0002] The rear suspension tie rod of the car is an important component connecting the engine and the body. With the continuous improvement of automobile design and technology, some of the previous suitable structures will be outdated, and new structures need to be replaced to meet new requirements. The powertrain of the current car is getting more and more advanced, and the torque provided by the unit power is getting bigger and bigger. On the one hand, it provides the car with better acceleration, climbing ability and suspension. up the challenge. The prevalence of electric vehicles also brings new challenges to the car body. Compared with gasoline vehicles, the greater torque of electric vehicles provides better acceleration and "push back feeling"....

AI Technical Summary

Problems solved by technology

[0004] The invention overcomes the problem that the current rear suspension rod cannot adapt to the higher and higher torque of the current automobile action assembly, resulting in insufficient service life to meet the design requirements, and provides a rear suspension for connecting the power assembly and the front sub-frame Suspension tie rod structure, which improves the torsion resistance effect of the tie rod and better torsion resistance, which improves the life of the tie rod
