The invention provides a vibration damper with double soft cushions. The vibration damper with the double soft cushions comprises a first support and a second support, wherein the first soft cushion is arranged between the first support and the second support; the second soft cushion is arranged on the second support; a gasket is arranged on the second soft cushion; the first support, the first soft cushion, the second support, the second soft cushion and the gasket are sequentially connected to one another fixedly through a fixing bolt; a nut of the fixing bolt is arranged on one side of the first support; a base of the fixing bolt is arranged on the gasket; the first support is welded on a hoop of a silencer; and the second support is welded to a frame support. By using the vibration damper with the double soft cushions, bidirectional vibration damping in the perpendicular direction is realized, influences of vibration of an engine and vibration of a whole vehicle on an exhausting system are reduced, the reliability of operation of the exhausting system is improved, and moreover, influences of vibration of the exhausting system on driving comfort are reduced.
Description
technical field [0001] The invention relates to vehicles and construction machinery components, specifically to a vibration damping device for an exhaust system, in particular to a double cushion vibration damping device. Background technique [0002] The exhaust system is an important part of automobiles and construction machinery. Due to the vibration of the engine and the whole vehicle during work, in order to ensure the reliability of the exhaust system, metal damping hoses and rubber cushions are usually used to The exhaust system is damped, so that the exhaust system can counteract the vibration transmitted by the engine and the whole vehicle. The traditional exhaust system damping device, because the cushion can only absorb vibration in one direction in the vertical direction, which brings risks to the work of the exhaust system. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a double cushion dampin...
