Engine assembly with suspension

Abstract

The invention discloses an engine assembly with suspension. The engine assembly comprises a power assembly, a left suspension assembly, a right suspension assembly and a rear suspension assembly; the left suspension assembly comprises a left suspension and a left suspension support, the left suspension comprises a base, a housing and a main rubber vibration absorbing pad, left and right ends of the base are bent upwardly, the bent portions are sleeved with fixed and vulcanized left and right rubber vibration absorbing pads, the housing comprises an inner plate and a rectangular outer cover which are connected fixedly, the periphery of the rectangular outer cover is provided with a flange, the rectangular outer cover covers the left and right rubber vibration absorbing pads and the main rubber vibration absorbing pad, and a clearance is formed between the left and right rubber vibration absorbing pads and the housing; the left suspension support is located right above the left suspension and is fastened with the housing through an installation bolt and a positioning pin, and the left suspension support is provided with an engine installation hole used for connecting with an engine. By the aid of the engine assembly, the vibration transmitted to a frame is reduced when the engine operates, the operations of the engine is limited, and resonance, and interference between the engine and other parts of an engine compartment during vehicle operation are avoided.

Description

technical field [0001] The invention relates to an automobile engine suspension structure, in particular to an engine assembly structure with suspension. Background technique [0002] The engine also becomes a power assembly, and the power assembly is provided with a left suspension assembly, a right suspension assembly and a rear suspension assembly as the left, right, and rear mounting points of the power assembly and the vehicle frame. The left suspension assembly and the right suspension assembly are respectively installed on the left and right sides of the powertrain, and the rear suspension assembly is installed behind the powertrain. [0003] The structure of the left suspension assembly is usually the same as that of the right suspension assembly, and the left suspension assembly is usually composed of a left suspension and a left suspension bracket. The left suspension usually includes a suspension upper plate, a suspension lower plate and rubber vibration damping ...

AI Technical Summary

Problems solved by technology

The main problem of this structure is that the engine vibration cannot be well decoupled, resulting in engine vibration, and the vibration is too large to cause resonance of other parts of the car body, the vibration inside the car is obvious, and the noise is loud

The rear suspension bracket is usually a stamped "U"-shaped frame, which cannot meet the boundary conditions of the transmission and the vehicle during installation. The rear suspension bracket has a low mode and cannot avoid the second-order and fourth-order excitation of the engine, resulting in resonance However, it affects the life of the rear suspension and cannot meet the NVH performance requirements
