Engine hydraulic mount assembly

Abstract

The invention relates to an engine hydraulic suspension assembly, which comprises a main spring, a dustproof cover, a turbulent flow disc, a flow passage cover plate, a flow passage, a lower liquid chamber, an installing support frame, a decoupling diaphragm, an upper liquid chamber and a main spring support frame, wherein a circle of outwards projected structure is arranged at a position near the lower end of the dustproof cover; a U-shaped groove is formed in a position, opposite to the projected structure, of the inner side of the dustproof cover; the upper end of the main spring support frame is arranged in the U-shaped groove and is in riveted and pressed connection, and the lower end of the main spring support frame is connected with the installing support frame in a riveting and pressing way. The technology has the advantages that the installing support frame is downwards moved, so the dustproof cover and the main spring support frame realize the direct riveting and pressing, and in the position, the riveting and pressing sandwich layer only has the main spring support frame, so the riveting and pressing is more reliable, meanwhile, the riveting and pressing force required by single-layer riveting and pressing is smaller, the edge riveting and pressing is adopted for riveting and pressing, and the influence on the assembly anti-corrosion performance due to large-area damage of a paint film of the riveting and pressing surface is avoided.

Description

technical field [0001] The invention belongs to the field of engine mounts, in particular to an engine hydraulic mount assembly. Background technique [0002] For the engine side mount, in order to improve its vibration isolation performance at high frequencies, it is generally designed as a hydraulic mount. The main forms of hydraulic mounts on the market are square mounts and circular mounts. Generally speaking, the main structure of the square mount adopts a casting structure. This kind of structure has more space for the change of the mount structure, and is suitable for vehicles with relatively narrow engine compartments; while for the circular mount, it is mainly a stamping and welding structure. This kind of mount has many processing steps, but the cost is relatively low, and because the lateral dimension of this kind of structural mount is relatively large, it is often used in models with relatively large engine compartment space.
