Embodiment Construction
[0025] see first figure 1 , figure 1 is a schematic top view of a diesel engine 1 provided with a flexible bracket according to the present invention. As shown in the figure, the flexible support 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 . like 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 flexible bracket acco...

The invention relates to internal combustion engines and provides a flexible support used for a diesel engine. The flexible support used for the diesel engine aims at solving the problem that an existing supporting system of the diesel engine can not effectively restrain vibration. The flexible support comprises a first sliding rail, a second sliding rail, a third sliding rail, a fourth sliding rail, a first sliding block, a second sliding block, a third sliding block, a fourth sliding block, elastic components, a first connection rod, a second connection rod, a third connection rod and a fourth connection rod, wherein the first sliding rail, the second sliding rail, the third sliding rail and the fourth sliding rail are fixed on a vehicle frame; the first sliding block, the second sliding block, the third sliding block, the fourth sliding block and the elastic components are arranged in the sliding rails respectively; the first connection rod, the second connection rod, the third connection rod and the fourth connection rod connect the sliding blocks with the diesel engine. By the adoption of the structure, vibration of the diesel engine in the vertical direction is converted to horizontal sliding of the sliding blocks along the sliding rails, the horizontal sliding is greatly attenuated by the elastic components on the two sides of the sliding rails, and therefore transmission of vibration of the diesel engine to the vehicle frame and a passenger cabin is effectively restrained, and the NVH characteristic of motor vehicles is improved.
Description
technical field [0001] The invention relates to an internal combustion engine, and specifically provides a flexible support for a diesel engine. Background technique [0002] The vibration of the diesel engine—especially the in-line cylinder diesel engine is mainly caused by the up and down reciprocating motion of the piston in the cylinder. Correspondingly, the vibration of the diesel 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] The existing diesel engine support structure mainly isolates the vibration of the diesel engine 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 se...
