Example Embodiment

[0025] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings, but this embodiment should not be construed as a limitation to the present invention.

[0026] The invention is like figure 1 with figure 2 Shown:

[0027] A rubber cushion for the front suspension of an engine, comprising two separate structures of an upper rubber cushion 1 and a lower rubber cushion 2. The upper rubber cushion and the lower rubber cushion have the same structure and are arranged symmetrically upward and downward in a mirror. The upper frame 3, the lower frame 4 and the rubber body 5 arranged between the upper frame and the lower frame are coaxially arranged, wherein:

[0028] The rubber body 5 has an outer cylindrical inner conical surface structure, and the outer cylindrical and inner conical surfaces have the same central axis, wherein: the upper port diameter of the inner conical surface is larger than the lower p...

Abstract

The invention discloses a front suspension rubber cushion for an engine. The front suspension rubber cushion comprises an upper rubber cushion and a lower rubber cushion with the same structure and symmetrically arranged in a mirror upward and downward direction. The upper rubber cushion and the lower rubber cushion comprise an upper framework, a lower framework and a rubber body arranged in the middle, wherein the upper framework and the lower framework are coaxially arranged, the rubber body is of an outer cylindrical inner conical surface structure, and the outer cylinder and the inner conical surface have the same central axis. The diameter of an upper port of the inner conical surface is larger than the diameter of a lower port; the lower framework is embedded in the bottom surface ofthe rubber body and integrally formed through vulcanization, the center of the lower framework is provided with a central sleeve mounting portion for mounting a center sleeve; the upper framework isarranged inside the upper end of the rubber body and integrally formed through vulcanization, the upper framework extends upwards along a central hole and is provided with a protrusion extending out of the surface of the rubber body, and the protrusion is used for being inserted into a mounting hole of a frame side support to prevent radial displacement; and the outer peripheral surface of the rubber body is wrapped with a hoop strap, an upper flange and a lower flange. The front suspension rubber cushion has good noise reduction and vibration damping effect while ensuring the suspension stiffness performance.

Description

technical field [0001] The invention relates to the technical field of engine installation, in particular to a rubber cushion for front suspension of the engine, which is used for connecting the engine with the vehicle frame and has the functions of noise reduction and vibration reduction. Background technique [0002] In order to reduce the vibration and noise generated during the whole driving process of the vehicle, the automobile engine adopts a vibration-damping mount mounted on an elastic support. Among them, the rubber mount is still widely used in the field of commercial vehicles. [0003] In the process of realizing the present invention, the inventor found that: [0004] In order to improve the ride comfort and comfort of the vehicle as much as possible, the stiffness performance index of the suspension is often set very low, but this design will inevitably reduce the fatigue performance of the product and affect the quality of the vehicle to a certain extent.
