Problems solved by technology
[0003] In the traditional construction machinery, agricultural machinery, etc., the cab, engine, deceleration mechanism and frame are mainly connected by rubber shock-isolating pads or directly rigidly connected in the shock-absorbing mechanism. The shock-isolation effect is poor, and the amplitude of the shock absorber is small

The invention discloses a vibration reducing mechanism. The vibration reducing mechanism comprises an inflation valve, a piston rod, a guide flange cover, a piston cylinder, a spring I and a spring II, wherein the piston rod is a welding structure, and is formed by welding a flange at the upper end, a steel pipe in the middle and a piston at the lower end; the flange is provided with the inflation valve; the piston moves in the piston cylinder; a damping small hole is formed in middle of the piston for communicating with the piston cylinder and an inner cavity of the piston rod; the spring II is arranged between the bottom of the piston cylinder and the piston; the guide flange cover coats the piston rod, and is fixed at the upper end of the piston cylinder; the spring I is connected between the lower part of the guide flange cover and the piston; hydraulic oil is filled in a hydraulic cylinder and the inner cavity of the piston rod; and the inner cavity of the piston rod has a certain height h. The vibration reducing mechanism can absorb the vibration through the springs in the vehicle vibration process; meanwhile, the structure of the hydraulic oil and the damping hole can prevent a cab from rebounding under the bumpy working condition; and the springs have the effects of limitation and protection to prevent excessive inclination of the cab caused by excessive elongation of the piston rod on a pavement with larger inclination.
Description
technical field [0001] The invention relates to a shock absorbing mechanism, in particular to a supporting shock absorbing mechanism for cabs, engines and deceleration systems of vehicles such as engineering machinery, agricultural machinery and special machinery. Background technique [0002] With the improvement of living standards and the rapid development of engineering construction and agricultural mechanization, people have higher requirements for the comfort of driving construction machinery and agricultural machinery. In order to meet market demand, taking a typical loader in construction machinery as an example, drivers have higher and higher requirements for safety, reliability, environmental protection and comfort. Especially for some high-end loaders, the vibration and noise control requirements in the cab are very high. A cab with excessive noise and strong vibration is unacceptable to the operator, while the operating environment with low noise and soft vibrati...
