Description
Technical field
The present invention relates to a kind of bicycle driving device, be specifically related to a kind of elastic force type bicycle front drive device, belong to bicycle and man field.
Background technology
Bicycle is the vehicle and the health and fitness facilities being loved by the people, and especially in China, user is numerous especially, is universally acknowledged " bikedom ".Along with people are in recent years to the improving constantly of healthy attention and environmental consciousness, bicycle is as the proportion of bodybuilding equipment in rapid raising, and quantity is constantly soaring.At present, the drive system major part of bicycle is that chain type drives, and is mainly made up of chain and sprocket wheel.Type of drive is back-wheel drive mostly.The bicycle using now exists following problem and shortage: during as the vehicle, and owing to only depending on back-wheel drive, propulsive effort deficiency is especially in the time of climbing, more obvious; During as health and fitness facilities, primary activity lower limb, very limited to the activity of upper limbs and whole body, affect train on.
Summary of the invention
The object of this invention is to provide a kind of elastic force type bicycle front drive device, propulsive effort and the body-building effect of bicycle can be provided.
To achieve these goals, the present invention is by the following technical solutions:
A kind of elastic force type bicycle front drive device, comprise two groups, and be separately positioned on the front-wheel left and right sides, every group comprises ratchet, track adjusting wheel, elastic webbing and catch bar, ratchet is arranged on front-wheel wheel shaft, catch bar upper end mounting knob, elastic webbing one end is connected with catch bar lower end, and the other end is connected with ratchet through track adjusting wheel.
In the embodiment of the present invention, catch bar comprises pull bar and is hinged on the power rail of pull bar end.
In the embodiment of the present invention, it also comprises the capable of regulating unit for adjusting track adjusting wheel position, track adjusting wheel is connected with power rail through guide wheel bracket, front-wheel is connected to front-wheel support one end, the front-wheel support other end is connected with catch bar, capable of regulating unit comprises the sliding sleeve that is arranged on front-wheel support, is arranged on the hook on sliding sleeve and the pull back spring between power rail and guide wheel bracket, and hook can snap together with guide wheel bracket end.
In the embodiment of the present invention, also comprise arrange on sliding sleeve and with hook hinged for together with activation members.
In the embodiment of the present invention, elastic webbing is curling flexible strip.
Principle of work of the present invention:
By being arranged on two pull bar devices of bicycle front handlebar position, in the time pressing or pull handle, utilize lever principle to drive ratchet to rotate by elasticity, thereby drive front-wheel to rotate.
Beneficial effect of the present invention:
1, can effectively increase propulsive effort, improve the effect of riding, especially, in climbing and the location that is difficult to walk such as muddy, the effect of power improvement is more obvious.
2, only need on existing bicycle, increase by two ratchets, two pull bars and two elastic webbings, the parts such as two pulleys and support, easy to manufacture, to install simply, cost is lower.
3, can make the more position of the human body such as upper and lower extremities, waist obtain activity and exercise, significantly strengthen train on, thereby improve the people's fitness and the general level of the health, its social benefit is very remarkable.
Brief description of the drawings
fig. 1 is structural representation of the present invention.
In figure 1, pull bar, 2, sliding sleeve, 3, activation members, 4, front-wheel support, 5, ratchet, 6, front-wheel, 7, hook, 8, guide wheel bracket, 9, pull back spring, 10, power rail, 11, track adjusting wheel, 12, handle, 13, elastic webbing.
Detailed description of the invention
Understand for the ease of those skilled in the art, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
With reference to accompanying drawing 1, a kind of elastic force type bicycle front drive device, comprise two groups, and be separately positioned on front-wheel 6 left and right sides, every group comprises ratchet 5, track adjusting wheel 11, guide wheel bracket 8, elastic webbing 13 and catch bar, ratchet 5 is arranged on front-wheel 6 wheel shafts, catch bar comprises pull bar 1 and is hinged on the power rail 10 of pull bar 1 end, pull bar 1 upper end is handle 12, elastic webbing 13 one end are connected with power rail 10 lower ends, the other end is connected with ratchet 5 through track adjusting wheel 11, track adjusting wheel 11 is connected with power rail 10 through guide wheel bracket 8, front-wheel 6 is connected to front-wheel support 4 one end, front-wheel support 4 other ends are connected with catch bar medium power bar 10.
In the present embodiment, also comprise the capable of regulating unit for adjusting track adjusting wheel 11 positions, capable of regulating unit comprises the sliding sleeve 2 that is arranged on front-wheel support 4, is arranged on the hook 7 on sliding sleeve 2 and the pull back spring 9 between power rail 10 and guide wheel bracket 8, and hook 7 can snap together with guide wheel bracket 8 ends.
In the present embodiment, also comprise arrange on sliding sleeve 2 and with hook 7 hinged for together with activation members 3.
In the present embodiment, elastic webbing 13 is curling flexible strip, can control ratchet 5 and return position.
Working process of the present invention is as follows:
In the time pressing or pull handle 12, catch bar action, drives ratchet 5 to rotate by elastic webbing 13, thereby drives front-wheel 6 to rotate.In the time driving handle motion to end position, make ratchet 5 and catch bar turn back to initial position by the elastic force of elastic webbing 13, so that push-and-pull again.In the time that track adjusting wheel 11 turns to upper limit position, catch bar has become push rod, and bicyclist can be realized and be driven front-wheel by racking; When track adjusting wheel 11 is during in lower position, catch bar has become pull bar, and bicyclist can move to realize by pulling and drive front-wheel 6.
Catch bar has double action, and the one, as stress point and the transmission system of propulsive effort, accept and transmission of drive force; The 2nd, control the direction of riding, substitute original handle-bar.Due to left and right catch bar lean on very near, therefore, bicyclist is in pushing or while pulling, relatively the torque of steering shaft is little, can not affect normally and ride.In the time that needs change direction, bicyclist can move on to hand the outer end of handle, so just can increase torque, the direction thereby manipulation and control are ridden.
Above embodiment is only for illustrating that technical scheme of the present invention is not intended to limit, and affiliated field personnel modify according to the above description or part technical characterictic is equal to replacement, should belong to the technical scheme scope of request protection of the present invention.
