Engine rear suspension combination module and automobile front subframe assembly assembly

Abstract

The invention provides an engine rear mounting combined module and an automobile front auxiliary frame assembling assembly. The engine rear mounting combined module is formed by a module body arranged in an overlapped area between a three-point rear and a four-point rear mounting of a back transverse beam of the automobile front auxiliary frame, a first connection part connected with a three-point engine rear mounting pull rod and a second connection part connected with a four-point engine rear mounting support, wherein the first connection part is arranged on the module body; and the second connection part is arranged on the module body. The engine rear mounting combined module is arranged in the overlapped area between the three-point rear and the four-point rear mounting of the back transverse beam; by the use of the first connection part, rear mounting matching with the four-point mounting engine is achieved; by the use of the second connection part, rear mounting matching with the three-point mounting engine is achieved; and re-development of the whole front auxiliary frame can be avoided, so developing period and cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of automobile production and manufacturing, in particular to an engine rear suspension assembly module and an automobile front subframe assembly assembly having the above-mentioned engine rear suspension assembly module. Background technique [0002] In the automotive system, the powertrain composed of the engine, clutch and gearbox is installed on the chassis of the car through the suspension bracket. The suspension bracket has a good vibration isolation effect, which can not only reduce the vibration and shock from the engine, but also reduce Vibration and shock on the road surface. [0003] For a car with a front engine, the left and right mounting points of the engine are arranged on the body, and the front and rear mounting points are arranged on the front sub-frame assembly. The engine is divided into three-point type and four-point type according to the number of mounts. The three-point type generall...

AI Technical Summary

Problems solved by technology

The three-point suspension has the best motion compliance, because three points determine a plane, which is not affected by the deformation of the frame, and the natural frequency is low, and the effect of anti-torsional vibration is good; the four-point suspension has good stability and can overcome large Torque reaction force, but the torsional stiffness is relatively large, which is not conducive to isolating low-frequency vibration

[0004] The existing automobile front sub-frame assembly assembly can only be assembled into a three-point mount or a four-point mount. When the mounted engine or the supporting four-point suspension front sub-frame does not match the installed three-point suspension engine, the original front sub-frame needs to be refitted due to the difference in the rear suspension structure and the position of the rear suspension. Developed a new front sub-frame, in order to meet the impact of rigidity, strength, and collision collapse, it is necessary to repeatedly modify the structure of the front sub-frame itself, which increases the development cycle and development cost of the car, and also affects the safety performance of the vehicle
