Description

Technical Field

[0002] In the automobile automatic transmission actuator, the engagement and disengagement of the multi-plate clutch and brake, as well as the tightening and loosening of the belt brake, cannot be too sudden, so as to avoid gear shifting shock, affecting the riding comfort, and even causing damage to parts in the assembly. Therefore, in the hydraulic system of the actuator, a buffer device is specially provided to absorb the shock caused by the sudden increase in oil pressure. The purpose is to control the gear shift quality and avoid vibration or excessive engagement of the actuator. Among various buffer devices, hydraulic shock absorbers are actually used more. The reason why shock absorbers can buffer the pressure shock of hydraulic oil is that they can temporarily divert part of the hydraulic oil to a parallel oil circuit or cavity, so that the increase of oil pressure in the main oil circuit is much smoother, and the clutch or brake can be smoothly engaged. Shock absorbers can be divided into two types: piston type and valve type.

[0003] When the shock absorber is in use, if it encounters a large vibration, it may contact the wall of the shock absorber, which will cause damage to the shock absorber body, thus affecting the safety of use, and subsequent maintenance and inspection will also require a lot of effort.

[0004] Therefore, it is necessary to propose a shock absorber with high pressure air bag to solve the above problems. Utility Model Content

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figure 1-Figure 2 As shown, the shock absorber with high-pressure air bag includes a hydraulic shock absorber cylinder 1, a mounting block 7 is installed on the right side of the hydraulic shock absorber cylinder 1, a sealing gasket 6 is installed on the left side of the mounting block 7, an adapter block 5 is arranged on the left side of the sealing gasket 6, an inspection groove 4 is opened on the right side of the hydraulic shock absorber cylinder 1, a sealing groove 3 is opened on the right side of the hydraulic shock absorber cylinder 1, the inspection groove 4 is opened on the left side of the inner cavity of the sealing groove 3, the sealing groove 3 is communicated with the inner cavity of the hydraulic shock absorber cylinder 1, the adapter block 5 is matched with the inspection groove 4 in size, the mounting block 7 is matched with the sealing groove 3 in size, the mounting block 7 is threadedly connected in the inner cavity of the sealing groove 3, the adapter block 5 is inserted in the inner cavity of the inspection groove 4, the sealing gasket 6 fits in the inner cavity of the sealing groove 3, and an oil seal 2 is installed on the front side of the inner cavity of the hydraulic shock absorber cylinder 1.

[0026] The oil seal 2 and the sealing gasket 6 can achieve a good sealing effect on the hydraulic shock absorber cylinder 1. By removing the mounting block 7, the adapter block 5 can be taken out from the inner cavity of the inspection groove 4, thereby facilitating the inspection and treatment of the components in the inner cavity of the hydraulic shock absorber cylinder 1.

[0027] like Figure 1 , Figure 3 , Figure 4As shown, a shock absorber with high-pressure air bag is provided, in which a piston rod 8 is movably connected in the inner cavity of the hydraulic shock absorber cylinder 1, a piston valve 11 is fixedly connected to the back of the piston rod 8, a high-pressure air bag body 12 is installed on the back of the piston valve 11, and an inflation tube 17 is symmetrically installed around the inner cavity of the piston valve 11, and an extrusion plate 16 is fitted on the side of the inflation tube 17. A lifting ring 9 is fixedly connected in the middle of the front of the piston rod 8. There are four high-pressure air bag bodies 12, four inflation tubes 17, and the back of the inflation tube 17 is fixedly connected to the front of the high-pressure air bag body 12 and communicated with its inner cavity. A sealing plug 18 is inserted in the middle of the front of the inflation tube 17, and a mounting assembly 13 is symmetrically threaded around the outer wall of the piston valve 11. A spring 15 is fixedly connected to the front and back of the mounting assembly 13 close to the piston valve 11, and the other side of the spring 15 is fixedly connected to the outer wall of the extrusion plate 16.

[0028] By setting the piston rod 8, when the component connected thereto is working, the piston valve 11 will be driven to move in the inner cavity of the hydraulic shock absorber cylinder 1, and the hydraulic oil can achieve the effect of shock absorption. At the same time, by setting the high-pressure airbag body 12, when the vibration is too large, the high-pressure airbag body 12 will be driven to contact the back side of the inner cavity of the hydraulic shock absorber cylinder 1, so that the overall shock absorption effect can be improved, and the service life of the structure can be further guaranteed.

At this time, the adapter block 5 will be separated from the inner cavity of the inspection groove 4. The staff can inflate the high-pressure airbag body 12 in the inner cavity of the hydraulic shock absorber cylinder 1 through the inspection groove 4. After removing the sealing plug 18, the high-pressure airbag body 12 can be inflated through the inflation tube 17. If the high-pressure airbag body 12 needs to be replaced, the bolt 14 is removed and the mounting assembly 13 is taken out. At this time, the extrusion plate 16 can be separated from the inflation tube 17, so that the high-pressure airbag body 12 can be dismantled.
