Abstract
The utility model provides a speed-change rickshaw with a front and back pedal. The utility model is composed of a frame, a front wheel, a back wheel, a guiding mechanism and a driving mechanism. The driving mechanism thereof comprises a driving gear connected with a pedal crank, a big driven gear and a small driven gear arranged on the back axle, a guide wheel and a driving chain. When the rickshaw is pedaled forward, the small driven gear is stressed and is in the high speed state. When the rickshaw is pedaled backward, the big driven gear is stressed and is in the low speed state. The utility model has the advantage of simple speed-change structure which can ease the feeling of riding fatigue.
Description
The utility model relates to a kind of bicycle, particularly a kind of tricycle.It is the driving device of characteristics with the endless chain that the utility model also relates to a kind of.
The speed changer structure more complicated of existing bicycle, fragile, and bicycle is in the process of riding, and the people remains a kind of posture, is easy to generate tired sensation.
The purpose of this utility model is to provide plants and can pedal front and back, and the rickshaw of energy speed change, simplifies the structure of change-speed box, for the bicyclist brings convenience.
Composition of the present utility model comprises vehicle frame, front-wheel, trailing wheel, guiding mechanism, foot-operated crank, transmission device.Its transmission device comprises: with the driving gear that foot-operated crank links to each other, be installed on big ring gear, little ring gear, track adjusting wheel and messenger chain on the rear axle.
Advantage of the present utility model is: its speed change realizes by big ring gear, little ring gear and track adjusting wheel.During current pedaling, little ring gear is stressed, is in the adjustment state; When after when pedaling, big ring gear is stressed, is in lower-speed state.Its speed changing structure is simple.The bicyclist can change state of kinematic motion in speed change, the tonicity of conversion leg muscle, and sensation lessens fatigue.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of transmission device;
Fig. 3 is the A-A cutaway view of Fig. 2;
Fig. 4 is the B-B cutaway view of Fig. 3;
Fig. 5 is the C-C cutaway view of Fig. 2
For example the utility model is described in detail below:
The appearance structure of the speed change three-wheel vehicle that Fig. 1 is pedaled before and after being, its component part comprises: front-wheel 1, guiding mechanism 2, vehicle frame 3, railway carriage 4, trailing wheel 5, foot-operated crank 6 and transmission device.With reference to figure 2, transmission device comprises and rides driving gear 8 that crank 6 links to each other, is installed on big ring gear 9, little ring gear 10 on the rear axle 11, is installed on that track adjusting wheel 12 on the vehicle frame and chain 7 form.Power-transfer clutch is installed on trailing wheel.Driving gear 8 drives little ring gear 10 by chain 7 when foot-operated when the rider is firmly pedaled forward, is in fast state this moment.Firmly pedal backward when foot-operated as the rider, driving gear 8 drives greatly by gear 9 by chain 7, is in lower-speed state this moment.When firmly mentioning the drop handle of power-transfer clutch, car can retreat.
