Embodiment Construction
[0028] see first figure 1 , figure 1 is a schematic top view of an internal combustion engine 1 provided with a suspension assembly according to the invention. As shown in the figure, the suspension assembly 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 suspen...

The invention relates to a motor vehicle power system, and provides a suspension assembly for an internal combustion engine so as to solve the problem that an existing engine supporting system can not restrain vibration effectively. The suspension assembly comprises a first siding rail, a second siding rail, a third sliding rail, a fourth siding rail, a first sliding block, a second sliding block, a third sliding block, a fourth sliding block, elastic components, a first connecting rod, a second connecting rod, a third connecting rod and a fourth connecting rod, wherein the first sliding rail, the second sliding rail, the third sliding rail and the fourth sliding rail are fixed to a vehicle frame, the first sliding block, the second sliding block, the third sliding block and the fourth sliding block are arranged in the sliding rails respectively, and the first connecting rod, the second connecting rod, the third connecting rod and the fourth connecting rod are used for connecting the sliding blocks with the engine. By the adoption of the structure, vertical vibration of the engine is converted to horizontal sliding of the sliding blocks along the sliding rails, and the horizontal sliding is substantially attenuated by the elastic components arranged on the two sides of the sliding rails, so that the vibration of the engine is effectively restrained from being transmitted to the vehicle frame or the interior of a passenger cabin, and the NVH performance of a motor vehicle is improved.
Description
technical field [0001] The invention relates to a motor vehicle power system, and specifically provides a suspension assembly for an internal combustion engine. Background technique [0002] The vibration of the internal combustion engine—especially the in-line internal combustion engine is mainly caused by the up and down reciprocating motion of the piston in the cylinder. Correspondingly, the vibration of the internal combustion engine also mainly manifests itself 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] The existing engine support structure mainly isolates 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 i...
