Background technique
Shock absorber is widely used on automobile, locomotive, the impulse force produced when its Absorbable rod carwash, locomotive brake to reach cushioning effect, Security during to improve travelling comfort when taking and to travel.Traditional shock-absorbing device, no matter be metal spring or gas spring formula, all existing cannot the shortcoming of free adjustment stroke, the general structure all needing more complicated, or needing the length changing shock-absorbing device axostylus axostyle, the length of metal spring or the length of gas spring air chamber tubing realize the object changing stroke, these methods all more complicated, and it is large to implement difficulty, cost is high.
Model utility content
The technical problems to be solved in the utility model is, for the above-mentioned defect of prior art, provides a kind of two air chamber Motor Vehicle shock absorber.
The utility model solves the technological scheme that its technical problem adopts:
A kind of two air chamber Motor Vehicle shock absorber of structure, comprises the outer tube of socket mutually, interior pipe first air chamber and the second air chamber; Described outer tube is the stereoplasm tube that one end open one end is closed, described interior pipe is that closed at both ends, wherein one end close mouth offer foraminate stereoplasm tube, described interior pipe arranges duct occlusion bottom portion toward the outside, foraminate one end, and being inserted in outer tube by opening end, described first air chamber and described second air chamber are connected are arranged on described internal tube by cutting off piston;
Described first air chamber comprises outer tube connecting rod, the first air chamber main piston and the first valve, described outer tube one end is connected to bottom outer tube closed end, the described outer tube the other end is connected with the first air chamber main piston being arranged on described internal tube through described aperture, described first air chamber main piston is provided with through hole, described air chamber main piston, partition piston and inner tube wall form described first air chamber, the through hole be connected to each other described in described first air chamber passes through, outer tube connecting rod and valve and ft connection;
Described second air chamber comprises the second air chamber piston, the second valve, described second air chamber piston is fixedly connected with described partition piston, described second valve is arranged at the interior duct occlusion end not with through hole, closed end not with through hole on described second air chamber piston and described interior pipe and described inner tube wall form described second air chamber, and the region of described interior pipe madial wall between described second air chamber piston and described partition piston is provided with the washer limiting described second air chamber piston movement stroke.
Described in the utility model pair of air chamber Motor Vehicle shock absorber, wherein, described interior pipe madial wall is provided with the washer of two described second air chamber piston movement strokes of restriction.
Described in the utility model pair of air chamber Motor Vehicle shock absorber, wherein, described second valve place is provided with seal ring.
The beneficial effects of the utility model are: by arranging two air chamber, the compression volume of the first air chamber can be changed in the space that internal tube occupies by adjusting the second air chamber, and equally there is compressibility due to the second air chamber, can balance pressure mutually between two air chambers, thus reach the object changing shock absorber effective travel.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing:
Fig. 1 is two air chamber Motor Vehicle shock absorber structure schematic diagram of the utility model preferred embodiment.
Embodiment
Two air chamber Motor Vehicle shock absorber structures of the utility model preferred embodiment as shown in Figure 1, comprise the outer tube 8 of socket mutually, interior pipe 9 first air chamber 7 and the second air chamber 1; The stereoplasm tube that outer tube 8 is closed for one end open one end, interior pipe 9 offers foraminate stereoplasm tube for closed at both ends, wherein one end close mouth, interior pipe 9 arranges foraminate one end bottom outer tube 8 closed end, and being inserted in outer tube 8 by opening end, the first air chamber 7 and the second air chamber 1 are connected are arranged on interior pipe 9 inside by cutting off piston 4; First air chamber 7 comprises outer tube 8 connecting rod 6, first air chamber main piston 5 and the first valve 10, outer tube 8 one end is connected to bottom outer tube 8 closed end, outer tube 8 the other end is connected with the first air chamber main piston 5 being arranged on interior pipe 9 inside through aperture, first air chamber main piston 5 is provided with through hole, air chamber main piston 5, cut off piston 4 and interior pipe 9 inwall and form the first air chamber 7, first air chamber 7 by the through hole, outer tube 8 connecting rod 6 and the valve that are connected to each other and ft connection; Second air chamber 1 comprises the second air chamber piston 3, second valve 2, second air chamber piston 3 is fixedly connected with partition piston 4, second valve 2 is arranged at interior pipe 9 closed end not with through hole, and the closed end not with through hole on the second air chamber piston 3 and interior pipe 9 and interior pipe 9 inwall form the second air chamber 1.By arranging two air chamber, the compression volume of the first air chamber 7 can be changed in the space that interior pipe 9 inside occupies by adjusting the second air chamber 1, and equally there is compressibility due to the second air chamber 1, can balance pressure mutually between two air chambers, thus reach the object changing shock absorber effective travel.
Preferably, as shown in Figure 1, interior pipe 9 madial wall in above-described embodiment is provided with at the second air chamber piston 3 and the region cut off between piston 4 washer 11 that two limit the second air chamber piston 3 movement travel.
