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 . 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 flexible bracket a...

Abstract

The invention relates to an internal combustion engine and aims to solve the problem that the existing diesel engine support system cannot effectively suppress vibration. For this purpose, the present invention provides a flexible bracket for a diesel engine. The flexible support includes: first, second, third and fourth slide rails fixed to the vehicle frame; first, second, third and fourth slide blocks and elastic members respectively arranged in the slide rails ; and first, second, third and fourth connecting rods connecting the slider to the diesel engine. In the case of adopting the above structure, the vibration of the diesel engine in the vertical direction is converted into the horizontal sliding of the slider along the slide rail, and this horizontal sliding is greatly attenuated by the elastic members arranged on both sides of the slide rail, thereby effectively suppressing the vibration of the diesel engine. The transmission of vibration to the frame and cabin improves the NVH characteristics of the vehicle.

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...
