Abstract
The invention discloses a damper. An opening in the right end of a working cylinder is sealed by a damping cap. An opening in the left end of the working cylinder is sealed by a gland. A piston rod in a piston rod assembly penetrates a through hole in the gland. A piston in the piston rod assembly is in sliding fit with the inner wall of the working cylinder. A floating piston is arranged in the working cylinder. The outer wall of the floating piston and the inner wall of the working cylinder are in motive seal. An inner cavity of the working cylinder is divided by the floating piston into two independent chambers which are the oil chamber on the left side and the oil-gas mixing chamber on the right side. The oil chamber contains 100 ml of special damper oil, and the oil-gas mixing chamber contains 0.35-0.55 MPa of high-pressure gas and 39-41 ml of special damper oil. According to the damper, a gas chamber of a traditional structure is adjusted to be the present oil-gas mixing chamber, so that the damping performance of the damper is effectively improved without improving the air charge pressure of an air compressor, and defects in the prior art are well overcome under the limitation of existing equipment.
Description
Technical field
The invention belongs to motorcycle vibration absorber field, particularly relate to a kind of damper.
Background technique
As everyone knows, damper is the significant components on vibration damper, existing damper comprises clutch release slave cylinder and floating piston, wherein the opening of clutch release slave cylinder right-hand member is closed by damper cap, the opening of this clutch release slave cylinder left end is closed by gland, piston rod in piston rod assembly is through the via hole on this gland, and the inwall of piston in piston rod assembly and clutch release slave cylinder is slidably matched; Described floating piston is located in clutch release slave cylinder, adopts motive sealing mode to seal between its outer wall and inwall of this clutch release slave cylinder; Meanwhile, clutch release slave cylinder lumen segmentation is become two chambers independent of each other by floating piston, and is respectively the oil pocket on the left side and the air cavity on the right, and wherein oil pocket is built with 100ml Special shock absorber oil, and air cavity is built with 0.45MPa.The effect of air cavity is the Special shock absorber oil bubble prevented in oil pocket, thus ensures damping performance.From theory, if increase the pressure in air cavity within the specific limits, also damping performance can be improved.
But user in use, improve higher requirement, and existing damper cannot requirement completely to the damping performance of damper.
Summary of the invention
Technical problem to be solved by this invention is the damper providing a kind of damping performance good, and reduces the requirement to air compressor simultaneously.
Technological scheme of the present invention is as follows: a kind of damper, comprise clutch release slave cylinder (1) and floating piston (5), wherein the opening of clutch release slave cylinder (1) right-hand member is closed by damper cap (2), the opening of this clutch release slave cylinder left end is closed by gland (3), piston rod (4a) in piston rod assembly (4) is through the via hole on this gland, and the piston (4b) in piston rod assembly (4) is slidably matched with the inwall of clutch release slave cylinder (1); Described floating piston (5) is located in clutch release slave cylinder (1), motive sealing mode is adopted to seal between its outer wall and inwall of this clutch release slave cylinder, it is characterized in that: the lumen segmentation of clutch release slave cylinder (1) is become two chambers independent of each other by described floating piston (5), be respectively the oil pocket (A) on the left side and the air-fuel mixture chamber (B) on the right, wherein oil pocket (A) is built with 100ml Special shock absorber oil, and 0.35-0.55MPa pressurized gas and 39-41ml Special shock absorber oil are housed in described air-fuel mixture chamber (B).
Compared with conventional construction, original air cavity is adjusted to present air-fuel mixture chamber by the present invention, and 0.35-0.55MPa pressurized gas and 39-41ml Special shock absorber oil are housed in air-fuel mixture chamber.After adopting above structure, Special shock absorber oil occupies a lot of space, even if the pressure now not increasing pressurized gas also can increase the total pressure in air-fuel mixture chamber (B), thus improves damping performance of the present invention.Meanwhile, this also reduces the requirement to air compressor, make the damping performance that also effectively can improve this damper under the restriction of existing equipment, thus cut down finished cost.
As preferably, 0.45MPa pressurized gas and 40ml Special shock absorber oil are housed in described air-fuel mixture chamber (B).
Adopt above optimum configurations, effectively can improve damping performance, be convenient to again implement.
For the ease of implementing, the periphery of described floating piston (5) has twice circular groove vertically, a 0 type circle (6) is housed in each circular groove respectively, and floating piston (5) realizes motive sealing by these two 0 type circles and described clutch release slave cylinder (1).
In the present case, described clutch release slave cylinder (1) and damper cap (2) are welded and fixed.
Beneficial effect: the air cavity of conventional construction is adjusted to present air-fuel mixture chamber by the present invention, and 0.35-0.55MPa pressurized gas and 39-41ml Special shock absorber oil are housed in air-fuel mixture chamber, the damping performance of damper so just effectively can be improved when not improving air compressor inflation pressure, thus under the limitation of existing equipment, overcome the defect of conventional art existence well, and structure of the present invention is simple, easy to implement, there is good practicability.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
As shown in Figure 1, a kind of damper, is formed primarily of clutch release slave cylinder 1, damper cap 2, gland 3, piston rod assembly 4, floating piston 5 and 0 type circle 6.Wherein, the opening of clutch release slave cylinder left end is closed by gland 3, and the opening of clutch release slave cylinder 1 right-hand member is closed by damper cap 2, and this clutch release slave cylinder 1 is welded and fixed with damper cap 2.Piston rod 4a in piston rod assembly 4 is through the via hole on gland 3, and the inwall of piston 4b in piston rod assembly 4 and clutch release slave cylinder 1 is slidably matched.Floating piston 5 is located in clutch release slave cylinder 1, adopts motive sealing mode to seal between the inwall of its outer wall and clutch release slave cylinder 5.The periphery of floating piston 5 has twice circular groove vertically, a 0 type circle 6 is housed in each circular groove respectively, floating piston 5 realizes motive sealing by these two 0 type circles and described clutch release slave cylinder 1.
The lumen segmentation of clutch release slave cylinder 1 is become two chambers independent of each other by floating piston 5, is respectively the oil pocket A on the left side and the air-fuel mixture chamber B on the right.Wherein, oil pocket A built with the Special shock absorber oil of 100ml outsourcing, and is equipped with the Special shock absorber oil of 0.35-0.55MPa pressurized gas and 39-41ml Special shock absorber oil in the B of air-fuel mixture chamber.As preferably, 0.45MPa pressurized gas and 40ml Special shock absorber oil are housed in the B of air-fuel mixture chamber.All the other structures of the present invention, as piston rod assembly 4 etc., all identical with prior art, do not repeat at this.
