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

The invention discloses a power assembly with suspensions. The power assembly comprises a power assembly body, a left suspension assembly, a right suspension assembly and a rear suspension assembly. The rear suspension assembly comprises a rear suspension support and the rear suspension, wherein the rear suspension support is formed by welding an L-shaped bent plate and two vertical plates, the rear suspension comprises an installation seat, a rubber assembly and two sector rubber gaskets, the installation seat comprises an arc plate and side plates arranged on the two sides of the arc plate, the rubber assembly is integrally cylindrical and comprises the cylindrical shell and a rubber core pressed in the cylindrical shell, and the rubber assembly is welded to one side of the arc plate through the cylindrical shell. A metal ring is fixedly installed in an axial hole of each rubber gasket, the metal rings and the rubber assembly are coaxially arranged, and the rubber assembly and the two rubber gaskets stretch in the part between the two vertical plates of the rear suspension support and are fixedly connected with the two vertical plates through bolts. The power assembly reduces the vibration transmitted to a frame when an engine moves, and resonance and interference between the engine and other components of an engine room in movement 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...
