Abstract
The utility model provides an adjustable shock absorber which comprises an operation cylinder and an adjusting valve. An adjusting hole communicated with the adjusting valve is formed in the operation cylinder. The adjustable shock absorber further comprises an adjusting spring and a valve plate; the valve plate covers the adjusting hole; one end of the adjustable spring is connected with the valve plate in an abutting mode and the other end of the adjusting spring is provided with an adjusting nut used for adjusting the pre-tightening force of the adjusting spring. According to optimization of the structure, when hydraulic oil flows in the direction of the adjusting valve, the valve plate is firstly opened, the spring pressure on the valve plate is overcome, and a through hole formed in a bottom cover is opened, so that oil in an oil returning pipe enters an outer pipe, and therefore the adjustment of the additional damping force is achieved. In the process, a user can adjust an externally-arranged adjustor knob according to the requirements, pre-pressing or loosening of a spring of the adjusting valve is achieved, the pre-pressing force of the spring is increased and decreased, the difficulty of opening of the copper valve plate by the oil in the oil returning pipe is adjusted, and therefore the change of the damping force is achieved.
Description
Technical field
The utility model relates to a kind of adjustable shock.
Background technique
Adjustable product in the past is to wash spool open by fluid, and the size of the passive unimpeded sky of adjusting is adjusted damping, because be subject to the restriction on dimensional fits precision that part self makes, its sensitivity greatly reduces.
Traditional damping adjustment is to lean on the promotion to spool when work of the fluid of vibration damper inside, control unimpeded aperture and adjust the size of damping force, in this process, at first fluid need to overcome is seal ring and the frictional force that coordinates between endoporus on spool, then could moving valve core move and retreat to regulator, adjust the aperture of unimpeded sky, thereby realize the passive adjustment of damping, mismatch error due to the seal ring on spool and hole, cause the sensitivity of spool when driving valve to descend, even lose regulatory function.
The model utility content
The utility model technical issues that need to address are to provide a kind of adjustable shock, in order to address the above problem.
In the utility model, adjustable shock includes clutch release slave cylinder and modulating valve, has the adjustment hole that is connected with described modulating valve on described clutch release slave cylinder, and in the utility model, adjustable shock also includes Regulation spring and valve block; Described valve block is covered on described adjustment hole; One end of described Regulation spring and described valve block butt, the other end of described Regulation spring is provided be used to the adjusting nut of regulating described Regulation spring pretightening force.
Preferably, described valve block is the brass valve block.
The utility model provides a kind of adjustable shock, includes clutch release slave cylinder and modulating valve, has the adjustment hole that is connected with modulating valve on clutch release slave cylinder, also includes Regulation spring and valve block; Valve block is covered on adjustment hole; One end of Regulation spring and valve block butt, the other end of Regulation spring are provided with for the adjusting nut of regulating the Regulation spring pretightening force., by this structure optimization, when hydraulic oil flows to the modulating valve direction, at first open valve block, valve block overcomes prefabricated spring pressure thereon, open the unimpeded sky that is arranged on bottom, make the fluid in return tube enter outer tube, thereby realize an additional damping force adjustment; In this process, the user can adjust external regulator knob as required, and the spring of adjusting valve is carried out precompressed or loosens, and increases and reduce the precompression of spring, adjusts the interior fluid of return tube and opens the difficulty or ease of brass valve block, realizes the change of damping force.
Description of drawings
Fig. 1 is the partial structurtes schematic diagram of adjustable shock in a kind of embodiment of the utility model;
Fig. 2 is the partial structurtes schematic diagram of adjustable shock in the another kind of embodiment of the utility model;
Wherein: 1, clutch release slave cylinder, 2, valve block.
Embodiment
Below in conjunction with accompanying drawing, model utility is described in further detail:
As depicted in figs. 1 and 2, the utility model provides a kind of adjustable shock to include clutch release slave cylinder 1 and modulating valve, has the adjustment hole that is connected with modulating valve on clutch release slave cylinder 1, and in the utility model, adjustable shock also includes Regulation spring and valve block 2; Valve block 2 is covered on adjustment hole; One end of Regulation spring and valve block 2 butts, the other end of Regulation spring are provided with for the adjusting nut of regulating the Regulation spring pretightening force.
The adjustable shock that the utility model provides, its purpose is: improve the sensitivity that damping force is adjusted.
Design by said structure, the adjustable shock that the utility model provides, when its work, piston assembly is moved in clutch release slave cylinder 1, the space of cavity of resorption is compensated into by compression valve assembly by the fluid in outer tube, has guaranteed the continuity of working in folding process.
The fluid part of piston upper chamber enters cavity of resorption by piston assembly, and a part enters in adjustment valve in bottom by being assemblied in return tube on guider in addition.Owing to being provided with valve block 2 between clutch release slave cylinder 1 and modulating valve, structural design like this, when hydraulic oil flows to the modulating valve direction, at first open valve block 2, valve block 2 overcomes prefabricated spring pressure thereon, open the unimpeded sky that is arranged on bottom, make the fluid in return tube enter outer tube, thereby realize an additional damping force adjustment; In this process, the user can adjust external regulator knob as required, and the spring of adjusting valve is carried out precompressed or loosens, and increases and reduce the precompression of spring, adjust the interior fluid of return tube and open the difficulty or ease of brass valve block 2, realize the change of damping force.
The advantage of said structure design is: original work fluid is adjusted the passive adjustment damping force of spool aperture be improved to the damping force of being controlled active accommodation adjustment product by spring.Avoided because the spool that the abnormal friction that causes on matching relationship causes lost efficacy, thereby improved the sensitivity that damping force is adjusted, improved the reliability that product is adjusted.
Preferably, valve block 2 is the brass valve block.Select the making material of brass as valve block 2, in the working life that can improve valve block 2, improve life time of the present utility model.
