Description

High-speed heat dissipation single-cylinder disc type shock absorber
Technical Field
The utility model relates to an improvement invention of shock absorber especially relates to an improvement invention of high-speed heat dissipation monotube disc formula shock absorber.
Background
At present, a hydraulic inflatable shock absorber is generally adopted, the damping action of the hydraulic inflatable shock absorber converts the vibration kinetic energy of an automobile into the heat energy of oil liquid of the shock absorber, and the performance of the shock absorber is seriously influenced due to the rising temperature. Meanwhile, when the piston does high-frequency large-stroke motion, oil in the shock absorber foams, and damping force is obviously attenuated. And oil compensation is also a concern for most manufacturers. Therefore, the single-cylinder design is adopted to accelerate heat dissipation, but the outer cylinder is easy to deform due to welding of the spring disc, and piston movement, rotation clamping and the like can be caused due to the deformation of the outer cylinder.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that overcome prior art not enough, provide a rational in infrastructure, move stable high-speed heat dissipation single-cylinder disc shock absorber.
In order to solve the technical problem, the utility model discloses an adopt following technical scheme to realize: this kind of high-speed heat dissipation monotube disk shock absorber, including piston cylinder and piston rod, its characterized in that: a floating piston which is sealed and slides is arranged in the piston cylinder, an O-shaped sealing ring and a wear-resistant piston ring which are matched with the inner wall of the piston cylinder are arranged on the periphery of the corresponding floating piston, the floating piston divides the piston cylinder into a sealed oil cavity and a high-pressure gas cavity, the oil cavity is positioned above the high-pressure gas cavity, high-pressure nitrogen is filled in the high-pressure gas cavity, damping oil is filled in the oil cavity, the piston rod is movably arranged at the upper end of the piston cylinder in a penetrating manner, the inner end of the piston rod extends into the oil cavity, the piston is arranged at the inner end of the piston cylinder, throttling; the lower end of the piston cylinder is welded with a sleeve, and a spring disc is welded on the sleeve.
The periphery of the floating piston is provided with a first annular groove and a second annular groove, the wear-resistant piston ring is arranged in the first annular groove in a matching mode, and the O-shaped sealing ring is arranged in the second annular groove in a matching mode.
Grooves are formed in the upper end face and the lower end face of the floating piston.
The beneficial effects of the utility model are that the high-speed single-tube disc shock absorber that dispels the heat after the improvement, the single-tube oil-gas separation structure of innovative design, the piston area is showing to be increased, the increase of working area can produce bigger damping force and more excellent damping force curve, better suppression spring compression and resilience, long distance is able to restrain the foaming of oil effectively to the resistant decay performance, strengthens the bearing range greatly, 2 MPa's high pressure bears and does not have the idle stroke, and makes the reaction of damping more rapid sensitive; the oil compensation function of the bidirectional valve plate is innovatively designed, the oil compensation effect is effectively achieved, and the damping function of the hydraulic shock absorber is kept.
Drawings
The following describes the present invention in further detail with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The drawings show the structure of the present invention, and the details thereof will be further described with reference to the drawings. The high-speed heat dissipation single-cylinder disc type shock absorber comprises a piston cylinder 1 and a piston rod 2, a floating piston 3 which slides in a sealing manner is arranged in the piston cylinder 1, an O-shaped sealing ring 4 and a wear-resistant piston ring 5 which are matched with the inner wall of the piston cylinder 1 are arranged on the periphery of the corresponding floating piston 3, the wear-resistant piston ring 5 is a piston ring made of wear-resistant materials, the floating piston 3 divides the piston cylinder 1 into a sealed oil cavity 6 and a high-pressure gas cavity 7, the oil cavity 6 is positioned above the high-pressure gas cavity 7, high-pressure nitrogen is filled in the high-pressure gas cavity 7, damping oil is filled in the oil cavity 6, oil-gas separation is realized; the piston rod 2 is movably arranged at the upper end of the piston cylinder 1 in a penetrating manner, the inner end of the piston rod 2 extends into the oil cavity 6, the inner end of the piston cylinder 1 is provided with a piston 8, the piston 8 is provided with small throttling holes 9 which are uniformly distributed, two sides of each small throttling hole 9 are provided with two-way valve plates 10, and the directions of the two-way valve plates 10 are changed through the pressure intensity change of the piston 8 during movement, so that the oil compensation effect is effectively achieved, the damping function of the hydraulic shock absorber is kept, and the piston rod 2 is restored and compressed; the welding of 1 lower extreme of piston cylinder has sleeve 11, and the welding has spring holder 12 on the sleeve 11 to this effectively avoids when spring holder 12 welds the installation, makes piston cylinder 1 take place deformation, influences the motion of piston rod 2.
The periphery of the floating piston 3 is provided with a first annular groove and a second annular groove, the wear-resistant piston ring 5 is arranged in the first annular groove in a matching mode, and the O-shaped sealing ring 4 is arranged in the second annular groove in a matching mode.
