Powertrain with left, right and rear suspension components

Abstract

The invention discloses a power assembly with left, right and rear suspension components. The assembly comprises an assembly body, a left suspension component, a right suspension component and a rear suspension component. The rear suspension component comprises a rear suspension support and a rear suspension; the rear suspension support comprises an L-shaped bent plate and two vertical plates in a welded manner; the rear suspension comprises an installation seat, a rubber assembly and two section-shaped rubber gaskets; the installation seat comprises an arc plate and side plates arranged of two sides of the arc plate; the rubber assembly is cylindrical entirely and comprises a cylindrical housing and a rubber core installed in the cylindrical housing in a pressed manner, and the rubber assembly is welded to one side of the arc plate in a welded manner through the cylindrical housing; metal rings are fixedly installed in the axial holes of the rubber gaskets and are arranged coaxial to the rubber assembly, the rubber assembly and the rubber gaskets extend to the position between the two vertical plates of the rear suspension support and are fixedly connected to the two vertical plates through bolts. By the aid of the assembly, the vibration transmitted to a frame when an engine operates is reduced, 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 a suspension structure of an automobile power assembly and belongs to the technical field of mechanical structures. Background technique [0002] A left suspension assembly, a right suspension assembly and a rear suspension assembly are arranged on the vehicle power 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 left, right and rear suspension components usually consist of suspensions and suspension brackets. Due to structural constraints, the engine vibration cannot be decoupled well, resulting in engine vibration, and excessive vibration causes resonance of other parts of the body, resulting in obvious vibration and loud noise in the car. The suspension brac...

Problems solved by technology

Due to structural constraints, the engine vibration cannot be decoupled well, resulting in engine vibration, and excessive vibration causes resonance of other parts of the car body, resulting in obvious vibration and loud noise in the car

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