Description
Technical field
The utility model relates to bicycle front-wheel shock-absorbing technique, and relate in particular to a kind of incabloc function between front-wheel and car body lock can being pulled, and make the shock-proof front-fork assembly structure that still can keep buffer action between car body and the front-wheel, but and the protection lock mechanism of pulling.
Background technology
At present, existing part is emphasized mountain-climbing, how the bicycle of cross-country function can install Shock absorber between the transom (being front fork) of its handle and front-wheel, and constitute so-called shock-proof front-fork assembly, to absorb the vibrations of front-wheel by Shock absorber, and the knight can be had drive comfortable preferably and control performance, its shock-proof front-fork assembly pipe mainly comprises two front fork tubes that are provided in bicycle front-wheel both sides respectively, establish for the wheel axon by front fork tube, and connect by the shoulder seat of telescopic pipe that wears mutually with front fork tube and montant below, and be provided with relevant Shock absorber with front fork tube inside in telescopic pipe inside, to reach the effect of shock-absorbing, see through Shock absorber and relax front fork tube and the corresponding motion of takeing between the seat, and then reach the shock-proof effect of expection.
When the pedal of the mode treadled cycle that soars with buttocks as the bicycle knight or climbing, Shock absorber provides the telescopic action of front fork tube with two main bodys of shoulder seat, can therefore absorb the application force that the knight imposes on pedal, allows the knight more feel painstaking on the contrary when pushes pedals.Thereby, a kind of bicycle front fork structure as shown in Figure 1 appears: utilize the bolt 15 that is arranged in front fork tube 11 bottoms to lock the structure 20 of pulling with shock-absorbing and be spirally connected, and see through the lock mechanism of pulling and allow front fork tube 11 and shoulder seat (figure slightly) locking be integral, and then the incabloc function lock of front fork is pulled.
In addition; the front-wheel of Regular Bicycle is except in order to the travelling and turn to of control bicycle; in the middle of the process that drives of bicycle reality; rider regular meeting must drive bicycle in the mode that buttocks soars because of the relation of quickening, and this moment, rider's center of gravity will lean forward towards handle, was supported the application of force of rider's balance center of gravity by handle; simultaneously under this drives situation; can absorb rider's the strength that drives, need this moment one to lock the mechanism of pulling, absorb rider's strength to prevent shock-proof front-fork assembly.
Yet aforesaid shock-proof front-fork assembly structure is not have buffer action fully between its front fork tube and the shoulder seat under the state that the incabloc function lock is pulled, though that is: the lock of the incabloc function between front-wheel and the car body can be pulled, loses due pooling feature also.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of shock-proof front-fork assembly structure, and it can reach the effect that shock-absorbing and lock are pulled.
Another technical matters to be solved in the utility model is to provide a kind of buffer structure of shock-proof front-fork assembly; it can pull the incabloc function between front-wheel and car body lock and make the shock-proof front-fork assembly structure that still can keep buffer action between car body and the front-wheel, but and the protection lock mechanism of pulling.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of shock-proof front-fork assembly structure is provided, this shock-proof front-fork assembly is to be established for the wheel axon by a pair of front fork tube, and connect by the shoulder seat of telescopic pipe that wears mutually with front fork tube and montant below, and be equipped with in telescopic pipe inside one with the axle of shoulder seat connection and relevant Shock absorber; The outer race of this axle is provided with a stationary pipes that connects with front fork tube, the tube wall of this stationary pipes is provided with the pod parallel with axle, the corresponding tip body that stretches into pod that is provided with of this axle, this stationary pipes is horizontally set with a stop section that just can supply this tip body to stride at the end of travel of pod, and a rotational angle that is used to control axle, to select whether allow tip body stride into the adjustment assembly of stop section.
For solving above-mentioned another technical matters, the technical scheme that the utility model adopted is: the buffer structure that a kind of shock-proof front-fork assembly is provided, this shock-proof front-fork assembly is to be established for the wheel axon by a pair of front fork tube, and connect by the shoulder seat of telescopic pipe that wears mutually with front fork tube and montant below, and be equipped with in telescopic pipe inside one with the axle of shoulder seat connection and relevant Shock absorber; Wherein, the periphery of this axle system is arranged with a stationary pipes that connects with front fork tube, and this stationary pipes bottom system sees through connecting element and bolt and front fork tube Joint, and is lined with at least one damper element in the position that stationary pipes and front fork tube compress mutually.
The beneficial effect of the utility model first technical scheme is: since the utility model shock-proof front-fork assembly be equipped with in telescopic pipe inside one with the axle of shoulder seat connection and relevant Shock absorber, in order to relaxing the corresponding motion between telescopic pipe and the front fork tube, and then reach the effect of shock-absorbing; In addition, make to stride under the state of stop section,, and then pull locking than the incabloc function of big-movement between front-wheel and the car body via the telescopic action between the fixing effect between tip body and stationary pipes restriction front fork tube and the shoulder seat at tip body.
The beneficial effect of another technical scheme of the utility model is: because the stationary pipes bottom sees through connecting element and bolt and front fork tube Joint, and be lined with at least one damper element in the position that stationary pipes and front fork tube compress mutually, this damper element can be made of the plastics with elastic shrinkage effect, rubber assembly, so under local elasticity's contraction of damper element, can keep due vibration-absorbing function.
