Description

Reciprocating concentric sealing structure of motorcycle shock absorber

Technical Field

The invention relates to the technical field of shock absorbers, in particular to a reciprocating concentric sealing structure of a motorcycle shock absorber.

Background

The shock Absorber (Absorber) is used to suppress the shock when the spring absorbs the shock and then rebounds and the impact from the road surface. The damping device is widely applied to automobiles and is used for accelerating the attenuation of the vibration of a frame and an automobile body so as to improve the driving smoothness of the automobiles. When the shock absorber passes through the uneven road surface, although the shock absorbing spring can filter the shock of the road surface, the spring can still reciprocate, and the shock absorber is used for inhibiting the spring from jumping. In order to improve the running smoothness of the automobile, a shock absorber is arranged in the suspension in parallel with the elastic element, and is used for attenuating the shock. At the moment, the friction between the hole wall and the oil and the internal friction between oil molecules form damping force on vibration, so that the vibration energy of the automobile is converted into oil heat energy, and then the oil heat energy is absorbed by the shock absorber and is emitted into the atmosphere. When the cross section and other factors of the oil passage are not changed, the damping force is increased and decreased along with the relative movement speed between the vehicle frame and the vehicle axle (or the vehicle wheel) and is related to the viscosity of the oil.

The utility model discloses a damping device, including motorcycle, front wheel, rear wheel, bumper shock absorber, the cylinder body of its outside can protect its inside damper, fluid has generally all been stored to the inside of its bumper shock absorber that uses at present, kneck department at the cylinder body generally all is provided with the sealing ring and prevents spilling over of fluid, the sealing ring can lead to sealed effect to take place to descend along with the ageing of time when in-service use, the serious person then can cause the bumper shock absorber to appear weeping and cause the shock attenuation effect to become invalid, influence in-service use.

Meanwhile, the sealing mechanism of the shock absorber used at present is generally supported by a metal cylinder, the cylinder with a larger diameter is generally arranged for preventing the metal cylinder from deforming to cause shock absorption failure, the length of the cylinder is fixed, the stroke of the shock absorber of the connecting rod in the cylinder can be limited, the maximum stroke of the whole shock absorber is limited immediately at the moment, and the shock absorption requirements of motorcycles with different specifications can not be met.

Because the bumper shock absorber generally all installs the side at the motorcycle, and the service environment of motorcycle is generally comparatively abominable, this surface that has just led to the bumper shock absorber can receive the invasion of rainwater or dust, and some rainwater itself has certain corrosivity, if do not clear up it for a long time will lead to the bumper shock absorber surface to appear corroding the phenomenon, and generally all need the manual work to clear up it among the current device, can not do the surface of quick clearance bumper shock absorber sealing tube.
