Abstract
The utility model relates to a front shock absorber of a motorcycle, which comprises a sleeve, a front breeches pipe, a shock absorbing spring and a piston rod, wherein the front breeches pipe is located in the sleeve, and glidingly matched with the sleeve; the shock absorbing spring is located in the front breeches pipe; the lower end of the shock absorbing spring is connected with the piston rod; the density degree of the shock absorbing spring is consistent; an air bag is arranged in a circumferential direction outside the shock absorbing spring, and fixed on an inner wall of the front breeches pipe; and a vent is formed in a wall of the front breeches pipe, and communicated with the air bag. With the adoption of the front shock absorber of the motorcycle, an elastic force of the motorcycle can be controlled effectively, and bending at the transition part between the dense coils and the sparse coils of the spring can be avoided.
Description
Technical field
The utility model relates to a kind of bumper, is specifically related to a kind of front damper of motorcycle.
Background technology
Front damper of motorcycle can be decayed rapidly and be changed the impact and the vibrations that bring because of car weight, load and various road conditions, greatly improve the damping performance of motor bike, raising in various degree motor bike ride comformability, traveling comfort, stationarity and safety, at present, the spring design of motor bike spring damper generally all adopts pitches, its spring performance line is the broken line that has break, easily there is the buckling phenomenon of spring at the transition position of spring Mi Quan and thin circle, the elastic behavior of spring is affected, makes troubles to user.
Utility model content
The purpose of this utility model is to provide a kind of elastic force that can effectively control motor bike, avoids spring Mi Quan and dredge the front damper of motorcycle that buckling phenomenon appears in circle transition position.
To achieve these goals, the utility model provides a kind of front damper of motorcycle, comprise sleeve, front fork tube, damping spring and piston rod, described front fork tube is positioned at sleeve and sleeve bearing fit, described damping spring is positioned at front fork tube, described damping spring lower end is connected with piston rod, described damping spring density is consistent, described damping spring outer ring is upwards provided with air bag, described air bag is fixed on front fork tube inwall, on described front fork tube tube wall, be provided with air extractor vent, described air extractor vent and air bag are communicated with.
Adopt the front damper of motorcycle of technique scheme to have following advantage: by damping spring outer setting one deck air bag, make air bag provide an external force to damping spring, make damping spring under the effect of identical power, it is less to there is deformation in spring upper end, provide enough traveling comforts to user, in the time running into larger resistance, damping spring moves downward and departs from air bag External Force Acting, provide enough elastic forces to user, guarantee good damping effect, by the air bag of damping spring outer setting, be convenient to the elastic force that user reasonably controls motor bike, avoid damping spring because density is inconsistent, cause spring Mi Quan and dredge circle transition position occurring bending situation, extend the service life of damping spring.
As preferred version, consider that the control air bag of energy actv. is to damping spring institute externally applied forces, the built-in multiple air cavitys of described air bag, are longitudinal distribution and are socketed in damping spring top, three air cavitys are set on air bag, inflate operation by the air extractor vent connecting.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model front damper of motorcycle embodiment;
Wherein: 1, sleeve, 2, front fork tube, 3, damping spring, 4, air bag, 5, piston rod.
the specific embodiment
Below in conjunction with drawings and Examples, technical solutions of the utility model are further illustrated:
As shown in Figure 1, the utility model provides a kind of front damper of motorcycle, comprise sleeve 1, front fork tube 2, damping spring 3 and piston rod 5, front fork tube 2 is positioned at sleeve 1 and sleeve 1 bearing fit, damping spring 3 is positioned at front fork tube 2, damping spring 3 lower ends are connected with piston rod 5, damping spring 3 density are consistent, damping spring 3 outer rings are upwards provided with air bag 4, air bag 4 is fixed on front fork tube 2 inwalls, on front fork tube 2 tube walls, be provided with air extractor vent, air extractor vent and air bag 4 are communicated with, in addition, as preferred version, as preferred version, consider that the control air bag 4 of energy actv. is to 3 externally applied forces of damping spring, the built-in multiple air cavitys of air bag 4, be longitudinal distribution and be socketed in damping spring top, three air cavitys are set on air bag, inflate operation by the air extractor vent connecting.
In actual front damper of motorcycle working process: first can regulate the charge air in air bag 4 by air extractor vent, because air bag 4 is built-in with three air cavitys, can inflate the top air cavity of air bag 4, after top air cavity is full of, continue bottom air cavity to inflate, can actv. control air cavity to 3 externally applied forces of damping spring.
Above-described is only preferred implementation of the present utility model; should be understood that; for a person skilled in the art; do not departing under the prerequisite of the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
Claims (2)
1. a front damper of motorcycle, comprise sleeve, front fork tube, damping spring and piston rod, described front fork tube is positioned at sleeve and sleeve bearing fit, described damping spring is positioned at front fork tube, and described damping spring lower end is connected with piston rod, it is characterized in that: described damping spring density is consistent, described damping spring outer ring is upwards provided with air bag, described air bag is fixed on front fork tube inwall, on described front fork tube tube wall, is provided with air extractor vent, and described air extractor vent and air bag are communicated with.
2. front damper of motorcycle according to claim 1, is characterized in that: the built-in multiple air cavitys of described air bag, are longitudinal scalariform and are socketed in damping spring top.
