Rear suspension system of automobile longitudinal power assembly

Abstract

The invention discloses a rear suspension system of an automobile longitudinal power assembly, which comprises an upper bracket, a lower bracket and an elastic element, wherein the upper bracket and the lower bracket are arranged on a lower beam of the transmission case and obliquely extend upwards from both sides of the transmission case; and the elastic element is arranged between the upper bracket and the lower bracket arranged on both sides of the transmission case. On the premise of not changing the prior automobile power assembly and the vertical space relationship of the transmission case beam, the cushion room is increased and the action center of the elastic element is changed. The upper and lower brackets obliquely extend upwards from both sides of the transmission case, and the elastic element is arranged between the upper and lower brackets on both sides of the transmission case, so that the upward and downward arrangement of the elastic element is not restricted by the transmission case and the volume and amount of compression of the elastic element can be obviously increased as compared with those in the original design. Meanwhile, since the space permits, the elastic element and the horizontal surface can form an included angle, thereby optimizing the arrangement of the suspension system.

Description

technical field [0001] The invention relates to a rear suspension system of an automobile vertical power assembly. Background technique [0002] The lower beam of the automobile gearbox cushion is usually the lowest point of the vehicle frame. In order to ensure the passability of the whole vehicle, there is a certain height limit between the lower beam and the ground. However, the configuration of the automobile powertrain requires the position of the gearbox to be as low as possible, resulting in too little space for the cushion of the gearbox, and the cushion cannot provide enough volume and movement space to achieve the proper shock absorption and shock isolation effects. At the same time, due to the vertical arrangement of the elastic elements, the center of action of the elastic elements cannot be adjusted according to the moment of inertia of the powertrain to optimize the arrangement of the suspension system. Contents of the invention [0003] The object of the pr...
