Embodiment Construction

[0026] see first figure 1 , figure 1 is a schematic top view of an engine 1 provided with a vibration damping device according to the present invention. As shown in the figure, the damping device according to the present invention includes a first slide rail 101 , a second slide rail 201 , a third slide rail 301 and a fourth slide rail 401 . The first slide rail 101, the second slide rail 201, the third slide rail 301 and the fourth slide rail 401 are respectively fixed on the frame of the motor vehicle (not shown in the figure), so that the centerline of the first slide rail 101 and The centerline of the third slide rail 301 is parallel or collinear and the centerline of the second slide rail 201 is parallel or collinear with the centerline of the fourth slide rail 401 . Such as figure 1 As shown, the first slide rail 101 , the second slide rail 201 , the third slide rail 301 and the fourth slide rail 401 are hollow structures with both ends closed. The vibration damping ...

Abstract

The invention relates to a motor vehicle power system and provides an engine assembly with the vibration reduction function. The engine assembly solves the problem that an existing engine supporting system cannot effectively retrain vibration. The engine assembly comprises a vibration reduction device. The vibration reduction device comprises first, second, third and fourth sliding rails, first, second, third and fourth sliding blocks, elastic components, and first, second, third and fourth connecting rods, wherein the first, second, third and fourth sliding rails are fixed to a vehicle frame, the first, second, third and fourth sliding blocks and the elastic components are arranged in the sliding rails respectively, and the sliding blocks are connected with an engine through the first, second, third and fourth connecting rods. By the adoption of the structure, vibration of the engine in the vertical direction is converted into horizontal sliding of the sliding blocks along the sliding rails, and the horizontal sliding is greatly attenuated by the elastic components arranged on the two sides of the sliding rails, so that vibration of the engine is effectively restrained from being transmitted into the vehicle frame and a passenger cabin, and the NVH characteristics of a motor vehicle are improved.

Description

technical field [0001] The invention relates to a motor vehicle power system, and specifically provides an engine assembly with a damping function. Background technique [0002] The vibration of the engine, especially the in-line engine, is mainly caused by the up and down reciprocating motion of the piston in the cylinder. Correspondingly, the vibration of the engine is mainly manifested as shaking along the vertical direction. When this vibration is transmitted to the passenger cabin, it will greatly increase the noise and vibration that the occupants can hear, seriously affecting the NVH characteristics of the vehicle and the driving experience. [0003] Existing engine vibration damping devices mainly isolate engine vibration through damping rubber pads and the like, so that the vibration transmitted to the cabin is minimized. However, the vibration suppression effect of this isolation method is very limited, and as the service life of the motor vehicle increases, the ...
