Problems solved by technology

The radial and axial characteristics of the traditional connection plate cannot be decoupled, so that the radial stiffness and axial stiffness of the connection plate affect each other and restrict each other. When the two are coupled together, it is difficult to greatly improve the radial stiffness and axial stiffness. The ratio of stiffness is difficult to meet the higher performance requirements of the vehicle for comfort and handling

Abstract

The invention discloses a connecting assembly installed between a vehicle body and an automobile suspension, comprising an outer bracket and an inner bracket, wherein the outer bracket is sleeved on the outer side of the inner bracket; an annular through hole is formed between the inner bracket and the outer bracket, and a first elastic vibration isolator and a second elastic vibration isolator are arranged in the annular through hole at intervals. The first elastic vibration isolator is fastened between the outer bracket and the inner bracket; an outer surface of the second elastic vibrationisolator is fastened to an inner surface of the outer bracket, and a preset annular gap is provided between the inner surface of the second elastic vibration isolator and the outer surface of the inner bracket. The invention also discloses a vehicle body. The invention discloses a connecting assembly and a vehicle body, which are simple in structure, low in cost, reliable in connection, convenientto install and use, and can improve the ratio of the radial stiffness and the axial stiffness of the connecting assembly, so as to meet the higher performance requirements of the vehicle for comfortand maneuverability.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a connection assembly installed between a vehicle body and an automobile suspension and a vehicle body. Background technique [0002] The connecting plate between the car body and the car suspension, as the connection point between the suspension and the car body, needs to absorb the alternating impact load from the road surface, and the energy-absorbing parts also need to meet the durability performance requirements to ensure the kinematics of the suspension geometric stability. Rubber with lower axial stiffness is beneficial to absorb energy and improve comfort, and high radial stiffness is better for lateral support of automobile suspension, which is beneficial to improve steering maneuverability. The radial and axial characteristics of the traditional connection plate cannot be decoupled, so that the radial stiffness and axial stiffness of the connection plate affect eac...
