Abstract
The utility model relates to a vehicle damper, comprising four damping cylinders and one oil storage cylinder. The damping cylinder is composed of a cylinder and a piston; the oil storage cylinder is composed of a cylinder body, a compression valve, damping holes, etc.; an upper and a lower chamber are arranged in the cylinder body; the upper chamber is communicated with the atmosphere; the lower chamber is communicated with the upper chamber via the compression valve and the damping hole; each damping cylinder is connected in series and communicated with the lower chamber of the oil storage cylinder. The vehicle damper with the advantages of sensitive damping reaction, good integral stability, simple structure, easy fabrication, etc. is suitable for small and medium sized cars and trucks which have small loading capacities.
Description
The utility model relates to a kind of improved automobile shock absorber, belongs to the damper technique field.
Shock absorber is to be used to make the impact shock parts of decay rapidly in the automobile suspension system, and it is installed in parallel between vehicle frame and vehicle bridge with elastic element.Widely used shock absorber is the cartridge type hydraulic shock absorber on the automobile at present, and its principle is to utilize the relative motion of oil cylinder and piston, makes fluid flow into another inner chamber from an inner chamber through some narrow slits repeatedly, forms damping, thereby realizes the decay to vibration.This shock attenuation unit is that a shock absorber is all installed at corresponding each wheel place, and each shock absorber works alone, is independent of each other.This shock absorber, himself complex structure, as the double-acting type cylinder type damper, it is made up of three concentric cylinder barrels, piston, piston rod, 4 more than 20 parts such as control cock, himself existing operating cylinder has oil storage cylinder again, so also caused the higher shortcoming of complex structure, accuracy of manufacture and cost though it has the better damping performance; In addition, this shock absorber in use is subjected to the restriction of its absolute construction, the load of each shock absorber and damping capacity loss balance complementation mutually, and the vehicle frame resistance to overturning is not good enough, and cushioning performance also is difficult for being greatly improved.
The purpose of this utility model is to provide a kind of improved automobile shock absorber, and this shock absorber should have better cushioning performance, and simple in structure, be easy to make, cost is low.
The purpose of this utility model is achieved in that
A kind of vehicle shock absorber, be installed between vehicle frame and the vehicle bridge, its improvement is, it comprises 4 cushion cylinders 1 and an oil storage cylinder 2, wherein, each cushion cylinder comprises cylinder barrel, piston, its cylinder barrel, piston respectively with vehicle frame, axle attachment connects, oil storage cylinder comprises cylinder body 3, compression valve, damping holes 4 etc. are fixed on the vehicle frame, on its cylinder body has, lower chambers, compression valve, damping hole is positioned at, on the wall between the lower chambers, upper chamber is communicated with atmosphere, and lower chambers is passed through compression valve, damping hole is communicated with upper chamber, the connection of contacting mutually of each cushion cylinder, and be communicated with the oil storage cylinder lower chambers.
Above-mentioned shock absorber, described compression valve comprises the valve seat orifice on spring 5, taper valve core 6 and the wall, taper valve core top contacts with spring, bottom and valve seat orifice sealing contact.
Above-mentioned shock absorber, described damping hole is located on the taper valve core, and its aperture is 2-5MM.
Above-mentioned shock absorber, the cylinder barrel diameter of described cushion cylinder is 1/3-1/5 with the ratio of the diameter of cylinder of oil storage cylinder.
The utility model adopts that each cushion cylinder polyphone connects, and the version of a shared oil storage cylinder, make the load of each cushion cylinder and damping capacity loss balance mutually, when vibration takes place, whole device all participates in vibration damping, stationary performance is good, and the vibration damping reflection is sensitive, and has simple in structure, the advantage that is easy to make is particularly suitable for using on the less middle-size and small-size car of load carrying ability, the lorry.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the utility model structural representation.
Among the figure, 4 cushion cylinders 1 are installed between vehicle frame 9 and the forward and backward vehicle bridge 8 mutually side by side with 4 springs 10 of suspension system, and certainly, cushion cylinder also can place spring eye; When the suspension elastic element adopted the bow type spring steel plate, cushion cylinder can be loaded between cambered plate and the vehicle frame; On the cushion cylinder piston seal ring is housed, can guarantees the working seal between cylinder barrel and the piston; Pore 7 on the oil storage cylinder cylinder cap is used for linking up with atmosphere; Each cushion cylinder is communicated with by the pipeline polyphone; Oil storage cylinder is fixed on the vehicle frame, and its lower chambers inserts in the polyphone oil circuit; When wheel upward movement damper cylinder is in compression shape journey, the fluid of its piston top is opened the taper valve core 6 of oil storage cylinder compression valve, enters epicoele by cavity of resorption, and spring 5 is a soft spring, can make the damping of compression stroke less, impact so that make full use of the elastic moderation of elastic element; When wheel resets or move downward, taper valve core is closed, because the effect of damping hole 4, fluid replenishes slower, it is slow that cushion cylinder is upheld speed, make the impact shock of elastic element obtain decay, because each cushion cylinder is the polyphone bonded assembly, the load of a cushion cylinder can be shared by very fast cushion cylinder by each polyphone, so the volume of cushion cylinder is little and the vibration damping reflection is sensitive, waste of power is little, and has saved oil storage cylinder simultaneously, has simplified the structure and the oad of shock absorber greatly.The utility model cushioning performance is good, simple in structure, be easy to promote the use of.
