Abstract
The utility model discloses a front shock absorber structure of a motorcycle. The lower end of a front forked tube is hinged with a shock absorbing rocker arm; a shock absorber is arranged between a support lug of the front forked tube and the middle part of the shock absorbing rocker arm; the shock absorbing rocker arm is V-shaped; a cylindrical pin seat hinged with the shock absorber is arranged at the sunken bottom of the V-shaped structure of the shock absorbing rocker arm; and a transition reinforcing rib is arranged between the outer cylindrical surface of the cylindrical pin seat and each of two sides of the V-shaped structure of the shock absorbing rocker arm. The shock absorbing rocker arm is V-shaped, the cylindrical pin seat is arranged at the sunken bottom of the V-shaped structure of the shock absorbing rocker arm, the transition reinforcing rib is arranged between the outer cylindrical surface of the cylindrical pin seat and each of the two sides of the V-shaped structure of the shock absorbing rocker arm, and the two sides of the shock absorbing rocker arm are connected together through the pin seat and the reinforcing ribs, so that the rigidity of the whole shock absorbing rocker arm is improved, the impact resistance of the shock absorbing rocker arm is enhanced, the shock absorbing rocker arm is difficult to deform and break, the collision resistance of the motorcycle is enhanced, the bearing quantity of the motorcycle is increased, and the safety performance of the motorcycle is improved.
Description
Technical field
The utility model relates to a kind of shock absorber structure, relates in particular to a kind of shock absorber structure that is used in the motor bike front portion.
Background technology
What the front-wheel damping of motor bike was adopted is damping before the straight barrel type, application number is that 200920166593.3 Chinese patent specification sheets discloses a kind of front damping device of motor tricycle, it has a front fork tube, front fork tube is the S type, divide three sections of upper, middle and lowers, top in the front fork tube stage casing is provided with journal stirrup, hingedly in the bottom of front fork tube hypomere be provided with U-shaped shock-absorbing rocker arm, one end and the front fork tube of U-shaped shock-absorbing rocker arm are hinged, the other end is used for being installed in the wheel shaft of front vehicle wheel, be provided with bumper between the middle part of journal stirrup and U-shaped shock-absorbing rocker arm, the upper end of bumper is hinged to be arranged on the journal stirrup, and the lower end of bumper is same as the tubular key seat that is arranged on the middle indent bottom of U-shaped shock-absorbing rocker arm and cooperates with U-shaped shock-absorbing rocker arm is hinged.The shock-absorbing rocker arm of these innovation and creation is U-shaped, has a more flat bottom, its tubular key seat just is arranged on this bottom, do not contact between the both sides of tubular key seat and U-shaped shock-absorbing rocker arm, when the two ends of U-shaped shock-absorbing rocker arm are stressed, U-shaped shock-absorbing rocker arm can be out of shape, after bumper is compressed to the end, if the further stressed distortion that will cause U-shaped shock-absorbing rocker arm of U-shaped shock-absorbing rocker arm, owing to not supporting between the both sides of U-shaped shock-absorbing rocker arm, so that the non-deformability of U-shaped shock-absorbing rocker arm descends, the easy fracture of U-shaped shock-absorbing rocker arm causes the crashworthiness of motor bike low, bearing capacity is little, poor stability.
In addition, hypomere and the angle between the stage casing of the front fork tube of these innovation and creation are less, cause the stiffness degradation of front fork tube, easily produce distortion.
The utility model content
The purpose of this utility model provides a kind of front damper of motorcycle structure, to solve in the prior art because the non-deformability of U-shaped shock-absorbing rocker arm is low, the easy fracture of U-shaped shock-absorbing rocker arm, and the crashworthiness of the motor bike that causes is low, bearing capacity is little, the problem of poor stability.
In order to realize above purpose, the utility model adopts following technical scheme: a kind of front damper of motorcycle structure, the front fork tube that comprises the S type, the hinged shock-absorbing rocker arm that is provided with in the bottom of front fork tube, be provided with bumper between the journal stirrup that the top in front fork tube stage casing arranges and the middle part of shock-absorbing rocker arm, described shock-absorbing rocker arm is V-type, the bottom of the indent of the V-structure of shock-absorbing rocker arm has for the tubular key seat hinged with bumper, all has the transition reinforced rib between the both sides of the external cylindrical surface of tubular key seat and the V-structure of shock-absorbing rocker arm.
Have angle between the hypomere of described front fork tube and the vertical straight line, front fork tube is away from the bumper deflection.
Shock-absorbing rocker arm of the present utility model is V-type, and, the bottom of the indent of the V-structure of shock-absorbing rocker arm is provided with the tubular key seat, all has the transition reinforced rib between the both sides of the external cylindrical surface of tubular key seat and the V-structure of shock-absorbing rocker arm, key seat has been connected in the existence of the reinforced rib both sides with shock-absorbing rocker arm, increased the rigidity of whole shock-absorbing rocker arm, strengthened the impact resistance of shock-absorbing rocker arm, the not yielding fracture of shock-absorbing rocker arm, thereby strengthened the crashworthiness of motor bike, increased motor bike bearing capacity, improved the safety performance of motor bike.
Have angle between the hypomere of front fork tube and the vertical straight line, front fork tube is away from the bumper deflection, and the stage casing of front fork tube and the angle between the hypomere want large with respect to prior art like this, so that the rigidity of front fork tube strengthens, improve the impact resistance of front fork tube.

The specific embodiment
A kind of embodiment of front damper of motorcycle structure, in Fig. 1 ~ 4, its front fork tube 1 is the S type, have three sections, epimere, stage casing and hypomere, the hinged shock-absorbing rocker arm 4 that is provided with in the bottom of front fork tube 1, an end and the front fork tube 1 of shock-absorbing rocker arm 4 are hinged, and the other end of shock-absorbing rocker arm 4 is used for rotating the wheel shaft that is assemblied in wheel.The journal stirrup 2 that the top in front fork tube 1 stage casing arranges is provided with pin-and-hole on the journal stirrup 2.Shock-absorbing rocker arm 4 is V-type, and the middle part of shock-absorbing rocker arm 4 is provided with tubular key seat 5, and tubular key seat 5 is in the bottom of indent of the V-structure of shock-absorbing rocker arm 4.All has transition reinforced rib 6 between the both sides of the external cylindrical surface of tubular key seat 5 and the V-structure of shock-absorbing rocker arm.Be provided with bumper 3 between the middle part of journal stirrup 2 and shock-absorbing rocker arm 4, the upper end of bumper 3 is hinged by pin-and-hole and journal stirrup 2 on the journal stirrup 2, and the lower end of bumper is hinged by tubular key seat 5 and shock-absorbing rocker arm 4.
Have angle between the hypomere of front fork tube 1 and the vertical straight line, front fork tube 1 is away from bumper 3 deflections.
Key seat has been connected in the both sides of reinforced rib with shock-absorbing rocker arm, so that the overall performance of shock-absorbing rocker arm is better, is not easy to deform, and can well bear the pressure from wheel.
Same front fork tube is to the direction deflection away from bumper 3, so that the rigidity of front fork tube is larger.
