Problems solved by technology

In the shock absorber compression valve of the utility model, by setting a compensation valve spring piece between the stopper and the check valve piece, the compensation valve spring piece presses the check valve piece, the opening height of the compensation valve spring piece is small, and the stop valve is ensured. The return valve plate opens and closes relatively smoothly, and at the same time increases the sensitivity of the check valve plate switch, which can alleviate the abnormal noise caused by the non-return valve plate not responding in time to a certain extent. The abnormal sound of the shock absorber has not been fundamentally solved, the service life is short, and the assembly process of this utility model is complicated, and the cost and production efficiency is low

Embodiment 1

[0025] refer to figure 1 , this embodiment provides a compression valve assembly with an integrated compensation valve stopper, including a compensation valve stopper 6, a compression valve seat 5 and a compression valve screw 1; the compression valve seat 5 is provided with a first threaded through hole 11 and throttle hole 7, the compensation valve stopper 6 is set on one side of the compression valve seat 5, and the compression valve screw 1 is set on the other side of the compression valve seat 5, so After the compression valve screw 1 passes through the gasket 2, the first compression valve plate 12, the second compression valve plate 3, the compression throttle valve plate 4, and the first threaded through hole 11 in sequence, it is limited by the compensation valve Device 6 threaded connection.

[0026] refer to figure 2 , the surface of the compensation valve stopper 6 is circular, four through holes 9 are evenly arranged on the plane of the compensation valve stopp...

Embodiment 2

[0029] This embodiment provides a compression valve assembly with an integrated compensation valve stopper, which is an improvement on the basis of Embodiment 1: after the compensation valve stopper is connected with the compression valve screw, riveting fixed. The material of the compensation valve limiter is manganese steel alloy.

[0030] The compensation valve limiter and the compression valve screw rod are connected by threads first, and then riveted and fixed by rivets, which is more firm. The material of the compensation valve limiter is manganese steel alloy, which has good mechanical strength, wear resistance and long service life.

Embodiment 3

[0032] This embodiment provides the manganese steel alloy material used for the stopper of the compensation valve.

[0033] The components contained in the manganese steel alloy and their contents are: 70 parts by weight of iron, 15 parts by weight of manganese, 0.9 parts by weight of carbon, 1.2 parts by weight of silicon, 0.01 parts by weight of phosphorus, 1.5 parts by weight of zirconium, 0.2 parts by weight of molybdenum, chromium 0.8 parts by weight and 1.1 parts by weight of cobalt.

[0034] The particle size of the iron powder is 10-40 μm.

[0035] The preparation method of the high manganese steel alloy material comprises the following steps:

[0036] S1: Mix all the raw materials, and then put them into a vacuum furnace for vacuum pre-sintering at a temperature of 100°C for 1 hour to obtain the mixed raw materials;

[0037] S2: Put the mixed raw material obtained in step S1 in a smelting furnace, pass in argon gas, smelt at 700°C for 30 minutes, then pass in hydrogen...

Abstract

The invention provides a compression valve assembly with an integrated compensation valve limiter, and belongs to the technical field of assembling of vehicle shock absorbers. The compression valve assembly with the integrated compensation valve limiter comprises the compensation valve limiter, a compression valve seat and a compression valve screw; a first threaded through hole and a throttling orifice are formed in the compression valve seat; the compensation valve limiter is arranged on one side of the compression valve seat; the compression valve screw is arranged on the other side of thecompression valve seat; after successively penetrating through a gasket, a plurality of compression valve blocks, a compression throttling valve block and the first threaded through hole, the compression valve screw is in threaded connection with the compensation valve limiter. The problem of 'grunt' abnormal sound generated due to opening of a compensation valve block in a working process of a product is solved, and the service life of a shock absorber is prolonged.

Description

technical field [0001] The invention relates to the technical field of automobile shock absorber assembly, in particular to a compression valve assembly with an integral compensating valve limiter. Background technique [0002] With the development of the automobile industry, consumers have higher and higher requirements for automobiles, such as driving stability and quiet driving. However, driving stability and quietness have always restricted customers' driving experience with cars. In order to accelerate the attenuation of the vibration of the frame and the body and improve the driving comfort of the car, shock absorbers are installed inside the suspension system of most cars. [0003] The compression valve assembly is a key part of the shock absorber. The upper end of the compression valve seat of the traditional compression valve assembly needs to pass through the first gasket, the compensation valve plate, and the second gasket in sequence, and then connect the compen...
