Engine vibration isolator used on engineering machinery

Abstract

The invention discloses an engine vibration isolator used on engineering machinery. The engine vibration isolator comprises an engine vibration isolator body, a lower suspension piston, a nitrogen shock absorber and a sliding piston, wherein the engine vibration isolator body is fixed on the engine vibration isolator fixed chassis; an engine box body is arranged in the engine vibration isolator body; a plurality of groups of fixing bolts are arranged on the engine vibration isolator fixed chassis; an engine box vibration reduction pad is fixed to the lower surface wall of the engine box body,the engine box body is fixedly installed on the upper surface wall of an upper suspension piston through bolts, the upper suspension piston is arranged on the inner surface wall of the engine vibration isolator body, and an air sealing ring is fixed to the side surface wall, making contact with the engine vibration isolator body, of the upper suspension piston in a sealed mode. By arranging the engine box vibration reduction pad, an air chamber, a nitrogen cylinder, the nitrogen shock absorber and a telescopic spring, the problems that an engine vibration isolation device is short in service life and poor in vibration isolation effect are solved.

Description

technical field [0001] The invention relates to the technical field of engine auxiliary equipment, in particular to an engine vibration isolator used on engineering machinery. Background technique [0002] Introduction of relevant content: With the continuous development of the automobile industry, people have higher and higher requirements for the safety, comfort and environmental protection of cars, and higher and higher requirements for the vibration standards of cars. At present, engineers and technicians Technical upgrades have been made to the vibration of the car body caused by the impact from the road surface, but the vibration and noise problems generated by the car engine during operation have not been well resolved. Poor engine vibration isolation will not only affect the comfort in the car, but also damage the performance of the engine itself, so as to affect the service life of the car. In the existing design, vibration isolation devices are generally used to r...
