Description
Technical field
The utility model belongs to the technical field of bicycle, a kind of specifically autoamtic boosting bicycle.
Technical background
Our used bicycle now all is that the people steps the foot-operated hinge wheel that makes and rotates, and by chain minor sprocket is rotated, thereby trailing wheel is rotated.Even what have passes through the vibrations power-assisted, because it is by the vehicle seat power-assisted of jolting more up and down, its power-assisted effect is very limited.
The purpose of this utility model provide a kind of front and back wheel power-assisted simultaneously, can make bicycle speed increase autoamtic boosting bicycle near one times.
Technical scheme
This autoamtic boosting bicycle, comprise vehicle frame, activity is contained in the axis on the vehicle frame, be contained in the hinge wheel on the axis, front end is movably connected in the back car wooden fork on the axis, be contained in the trailing wheel of car wooden fork rear end, back, the minor sprocket with trailing wheel one side links together is connected with bumper between vehicle frame and back car wooden fork, the ratchet that links together with the opposite side of trailing wheel, be connected the large ratchet on the ratchet, activity is contained in the rocking arm on the ratchet, with rocking arm pivotally attached connecting rod, be hinged on that an end contacts with large ratchet on the rocking arm, the ratchet that the other end can contact with connecting rod, one end is fixed on the pull bar of an end and rod hinge connection on the vehicle frame, and the front truck wooden fork that connects to ground is contained in the front-wheel on the front truck wooden fork.
This autoamtic boosting bicycle, the front truck wooden fork comprises preceding damping, one end is connected with preceding damping, an end is contained in the front support rod on the front wheel spindle, be contained in the preceding ratchet that is connected as a single entity with front-wheel on the front wheel spindle side by side with front support rod, preceding large ratchet before being contained on the ratchet, one end is contained in stage casing and front support rod flexible connection, the other end and preceding damping shell bonded assembly front arm on the front wheel spindle, be hinged on that an end contacts with preceding large ratchet on the front arm, the other end can with the preceding ratchet that contacts when iron on the preceding damping shell.
Because vehicle frame and back car wooden fork all are movably connected on the axis, be connected with bumper between back car wooden fork and vehicle frame, the front truck wooden fork also is a bumper, and when the people is sitting in when pitching on the vehicle seat, the relative motion between back car wooden fork and vehicle frame is bigger, connecting rod drives rocking arm and does to move significantly; the motion of rocking arm drive ratchet rotate thereby drive large ratchet, and preceding ratchet also drives preceding large ratchet rotation when jolting; thus drive car rapid movement forward, the speed of a motor vehicle is nearly doubled when normally riding.It is also comfortable especially that the people is sitting in the top, and advance and fall back freely.
Description of drawings
Accompanying drawing shows embodiment of the present utility model, wherein:
Figure 1 shows that autoamtic boosting bicycle faces structural representation;
Figure 2 shows that along the office of A-A line shown in Figure 1 and cut open enlarged drawing;
Figure 3 shows that along the office of B-B line shown in Figure 2 and cut open enlarged drawing;
Figure 4 shows that along the office of C-C line shown in Figure 1 and cut open enlarged drawing;
Figure 5 shows that along the office of D-D line shown in Figure 1 and cut open enlarged drawing;
Embodiment
Autoamtic boosting bicycle as shown in the figure, comprise vehicle frame 1, be contained in axis 2 on the vehicle frame 1 by bearing seat 21 and bearing 22, be fixed on the hinge wheel 3 on the axis 2, front end is contained in back car wooden fork 4 on the axis 2 by bearing carrier ring 23 and bearing 24, be contained in the trailing wheel 5 of car wooden fork 4 rear ends, back by hind axle, the minor sprocket that links together with trailing wheel 5 one sides, be connected the chain between hinge wheel 3 and minor sprocket, be connected with bumper 6 at vehicle frame 1 and 4 of back car wooden forks, the ratchet 7 that links together with the opposite side of trailing wheel 5, be connected the large ratchet 9 on the ratchet 7, be contained in the rocking arm 8 of large ratchet 9 both sides on the ratchet 7, with rocking arm 8 pivotally attached connecting rods 10, be hinged on that an end contacts with large ratchet 9 on the rocking arm 8, ratchet 20, one ends that the other end can contact with connecting rod 10 are fixed on an end and connecting rod 10 pivotally attached pull bars 11 on the vehicle frame 1 by bearing seat 21, with vehicle frame 1 bonded assembly front truck wooden fork, be contained in the front-wheel 13 on the front truck wooden fork.The front truck wooden fork comprises preceding damping 12, the stage casing is connected with preceding damping 12, an end is contained in an end and preceding damping 12 shell bonded assembly front support rods 14 on the front wheel spindle, with front support rod 14 be contained in side by side on the front wheel spindle with front-wheel 13 bonded assemblys before ratchet 15, preceding large ratchet 16 before being contained on the ratchet 15, before one end is contained on the ratchet 15, the other end and preceding damping 12 shell bonded assembly front arms 17, be hinged on the preceding ratchet 19 that an end contacts with preceding large ratchet 16 on the front arm 17, the other end can contact with the buting iron 18 on preceding damping 12 shells.Because axis and vehicle frame and back car wooden fork all flexibly connect, thereby when jolting, back car wooden fork is a up-and-down movement, preceding damping also is a up-and-down movement, the up-and-down movement of the two drives rocking arm and front arm motion respectively, also drive simultaneously the motion of ratchet and preceding ratchet, also just drive large ratchet and preceding large ratchet respectively and rotate, thereby front and back are played power-assisted effect simultaneously.And because the effect of back damping and preceding damping makes the people comfortable especially above being sitting in, particularly all the more so on the road surface of jolting.And owing to the upper end of ratchet contacts with connecting rod, before the iron of working as in upper end and the preceding damping of ratchet contact, when damping rise in front and back puts in place, connecting rod is pressed in the upper end of ratchet, ratchet lower end and large ratchet are broken away from, and ratchet and the disengaging of preceding large ratchet before the buting iron on the preceding damping shell makes are risen when putting in place in preceding damping, get off bicycle need move backward the time as the people like this, can move.
