Abstract

The embodiment of the invention provides a vibration reduction device of an engine cooling water pipe and a vehicle, and relates to the field of mechanical vibration reduction devices. The vibration reduction device is used for reducing vibration of an engine and propagation of liquid pulsation produced by a water pump from axial and radial directions to a vehicle body through the cooling water pipe. The vibration reduction device of the engine cooling water pipe comprises a shell, a movable vibration reduction pipe is arranged in the shell in the axial direction, a second vibration reduction ring is sleeved outside the vibration reduction pipe, a first vibration reduction ring is arranged at one end in the shell in a sealing mode, and the first vibration reduction ring is thinner than the second vibration reduction ring. According to the embodiment, the vibration reduction device is applied in the field of manufacturing of automobiles.

Description

technical field [0001] The invention relates to the field of mechanical vibration damping devices, in particular to a vibration damping device for an engine cooling water pipe and a vehicle. Background technique [0002] Comfort, low noise and low cost are the development direction of the current automobile. As a main vibration source, the transmission of engine vibration not only directly affects the reliability and service life of the construction machinery. When the engine vibration is transmitted to the body through the cooling water pipes and warm air pipes in the car cooling system, it will directly affect the comfort of the vehicle. [0003] In the prior art, the cooling water pipes, the water tank, the warm air pipes and the dash panel in the automobile cooling system are mainly connected by hard rubber pipes, and a part of the engine vibration is isolated through the rubber and the direction of the rubber pipes. This method can only isolate the radial vibration of...
