Abstract
The invention relates to a novel composite valve assembly of a shock absorber, comprising a working cylinder, a flow and recovery valve system and a compensation and compression valve system which are arranged in the working cylinder; the flow and recovery valve system comprises a piston provided with a baffle block; a flow spring and a flow valve piece are arranged between the piston and the baffle block; the piston is connected with a spring seat and a recovery nut through the valve piece and a throttle valve piece; and the spring seat is provided with a recovery spring acted on the recovery nut. The novel composite valve assembly has the advantages that: the product assembling process becomes simple, is adaptive for stream line production, and improves the assembling efficiency; the process of a piston valve body, a compression valve body and a working cylinder roll groove of the valve system is cancelled after improvement, so the cost is reduced; the stability of batch production is improved, and the repair rate is reduced; the temperature sensitivity of the valve system is reduced; and the service life of the valve system is prolonged.
Description
Technical field
The present invention relates to vibration damper, especially a kind of novel damping device combination valve assembly.
Background technique
Vibration damper is to produce damping force to absorb the energy that tire vibration produces in vehicle traveling process, and valve system is the principal organ that produces damping force, and mainly by flowing valve and rebuilt valve sub-assembly, recuperation valve and compression valve sub-assembly are formed.When producing recuperability, rebuilt valve and the effect of compression valve device, when producing compressive force, flowing valve and compression valve work.
Existing valve body is assembled into assembling spring shield earlier, piston valve body, and the circulation spring, valve block, throttle valve plate, piston is assembled together earlier, and spring shield need be stuck on the piston, and this operation assembling difficulty height can only hand assembled.The existence of piston valve body and compression valve body influences the stability of damping force value, required precision height, processing cost height, and damping force and piston valve body and compression valve body are in close relations, and in actual production process, it is stuck that the clamping force of spring shield and piston is crossed conference simultaneously, damping force is bigger than normal, the vibration damper clamping stagnation; Too small meeting gets loose, and damping force is less than normal, and vibration damper is unable.
Existing valve body produces identical damping force, and the valve block distortion is little, shock absorber fluid flow velocity height, because circulation area is little, flow velocity is big, and vibration damper viscosity is big to the damping force influence, so damping force of vibration damper is responsive to temperature.Under abominable stress condition, valve block is the life-span because of being subjected to the frequent large deformation meeting of greater impact power to reduce valve, even fracture makes defective shock absorber at vibration damper.
Summary of the invention
The present invention will solve the shortcoming of above-mentioned prior art, provides that a kind of assembling is simple, low-cost, high-quality novel damping device combination valve assembly.
The present invention solves the technological scheme that its technical problem adopts: this novel damping device combination valve assembly, comprise clutch release slave cylinder, circulation that is provided with in the clutch release slave cylinder and resetting valve system and compensation and compression valves system, described circulation and resetting valve system comprise piston, piston is provided with block, circulation spring and circulation valve block are housed between piston and the block, and piston is connected with spring seat and restores nut by valve block and throttle valve plate, and spring seat is provided with and acts on the return spring that restores nut.
As preferably, described compensation and compression valves system comprise the compression valve seat, the compression valve seat is provided with snubber, and counterbalance spring and compensation valve block are housed between snubber and the compression valve seat, and the compression valve seat is connected with the compression valve rod that runs through snubber and compression valve seat by compression valve block and compression throttling valve block.
As preferably, described piston becomes whole with piston ring and is connected, with the simplification assembly process.
As preferably, described compression valve seat end face is provided with a circle groove, and compensation and compression valves system cooperate with clutch release slave cylinder and fix by compressing groove on the valve seat, have cancelled intrinsic clutch release slave cylinder slot rolling technology, have reduced cost.
The effect that the present invention is useful is: one, valve is that part only needs assembling sequentially, is fit to the production line effect, improves efficiency of assembling; Two, cancel piston valve body and compression valve body, reduced cost, eliminated above three factors that influence damping force, improved the stability of producing in batches, reduced repair rate; Three, replaced the single distortion of valve block by the composite deformation of return spring and valve block, because return spring is relative and valve block is little, compound aperture is big, and flow velocity reduces, and damping force of vibration damper varies with temperature little; Four, under abominable stress condition, the impact force that is subjected on the valve block is shared by valve block and spring, has reduced the stressed of valve block, improves the Endurance life of valve system.
