Embodiment Construction

[0029] see figure 1 As shown, the present invention is that an air spring 2 is installed on the outside of the double-tube oil-gas shock absorber 1 to form a composite damping structure.

[0030] refer to figure 2 , image 3 with Figure 4 As shown, the structure of the air spring 2 adopts a three-stage air spring with a capsule hollow structure, and the air spring 2 is sleeved on the outside of the double-tube oil-pneumatic shock absorber 1. The air spring 2 is composed of the first air bag 21, the second Two airbags 22 and the third airbag 23 constitute, the first airbag 21, the second airbag 22 and the third airbag 23 are stacked together, the first gasket 24 is placed on the first airbag 21, the first airbag 21 and the second airbag A second gasket 25 is sandwiched between the airbags 22 , a third gasket 26 is sandwiched between the second airbag 22 and the third airbag 23 , and a fourth gasket 27 is disposed at the bottom of the third airbag 23 .

Abstract

The invention discloses a damper with two-way throttle valves and an air spring. The air spring is arranged outside a dual-cylinder oil gas damper to form a composite damping structure; the dual-cylinder oil gas damper uses a piston with multiple two-way throttle valve structures on the basis of the traditional damper. The traditional dual-cylinder hydraulic damper is improved, and the throttle valves are additionally arranged on the work piston so as to realize the automatic control on the liquid flow; the dual-cylinder oil gas damper and the external air spring can synchronously bear a load by adjusting the rigidity of throttle valve springs, so the composite damping device with the true meaning is formed; the graded damping effect of the bag-type air spring with three air bags is achieved by adjusting the initial air pressure and the size of the air bags and the integral damping performance of the damper is improved; the energy loss of the damper is reduced by setting the throttle valves under the condition that the damping performance is not affected.

Description

technical field [0001] The invention relates to a shock absorber, in particular to a shock absorber with a two-way throttle valve and an air spring. Background technique [0002] The function of the shock absorber is to transmit the force and moment acting on its two ends, and to moderate the impact load, attenuate the vibration caused by it, ensure the smooth operation, and reduce the resulting dynamic load. [0003] There are still some defects in the damping performance of the existing mining car suspension mechanism. The damping force of the shock absorber of the passive suspension used in it cannot be adjusted according to the road conditions, and the frequent and severe relative friction between the frame and the axle The movement seriously affects the damping effect and service life of the suspension. In the actual operation of the mining area, due to the large load of the mining vehicle and the bumpy road conditions in the mining area, the small parts of the mining ...
