The chainless bicycle is characterized in that the power system comprises a driving wheel arranged on the frame and a pedal driving mechanism connected with the axle of the driving wheel, a support is connected with a stabilizing wheel, and the external diameter of the stabilizing wheel is smaller than that of the driving wheel. The chainless bicycle is simple in design, small in size, light and handy, and convenient, thereby having a good promotional value.
Description
Technical field
The utility model relates to the vehicle and technical field of sports apparatus, especially relates to a kind of Chainless Bicycle.
Background technology
Bicycle claims bicycle or bicycle again, normally the two small-sized land-going machines of taking turns.After the people rides car, being power with the foot pedal, is the vehicle of environmental protection.Present two-wheeled cycle used in everyday its to be shaped as volume relatively large, longer, need chain to drive simultaneously and reach the effect of advancing.But, because there is the gap in the interlock of sprocket wheel and chain, and chain and sprocket wheel meeting generation wearing and tearing after operation a period of time, cause chain elongated, interocclusal clearance increases, and in use causes chain and spoke deadlock to put user's trouser legs and foot on the spot easily, even can cause problem such as chain.And the vehicle frame of existing bicycle adds that the weight of two wheels tends to the bicyclist personnel are caused certain burden, influences riding speed.
Summary of the invention
The purpose of this utility model be exactly provide for the deficiency that solves prior art a kind of simple in structure, wide adaptability, easy to use, volume is little, easy to carry, modern design, and can solve the Chainless Bicycle or the body-building apparatus of people's trip, motion.
The utility model is to adopt following technical solution to realize above-mentioned purpose: a kind of Chainless Bicycle, comprise vehicle frame and go up control system, the power system that is provided with, it is characterized in that, described power system comprise the driving wheel that is arranged on the vehicle frame, with the wheel shaft bonded assembly pedal drive mechanism of driving wheel, be connected with the steady wheel of its external diameter on the support less than driving wheel.
As further specifying of such scheme, described driving wheel comprise the axle skin that is sheathed on the wheel shaft, in be provided with the wheel hub of ratchet, wheel hub is sheathed on outside the skin, the axle skin is provided with the ratchet that has spring and the ratchet activity clamping of described wheel hub, when wheel shaft rotated, the axle skin on the wheel shaft also can be along with being driven, and the ratchet on the axle skin can strut by spring at this moment, and snap in the draw-in groove of ratchet and drive wheel hub and rotate, drive whole wheel rolling.
Described pedal drive mechanism comprises and is connected in the connecting rod on the wheel shaft and is installed in stretcher on the connecting rod.
Described steady wheel is arranged on the support at the place ahead of driving wheel or rear.
The external diameter ratio of the external diameter of described steady wheel and driving wheel is 1:(2-8).
Described control system comprises control headstock, the wheel engine device that is positioned at the vehicle frame front end, and the top of driving wheel is equipped with mudwing, and the middle part of vehicle frame is equipped with saddle.
Described wheel engine device comprises brake control stalk that is installed in control headstock both sides and the brake facing that is arranged on the wheel nave outside, and the brake control stalk is connected with brake facing.
Be provided with recoil spring between described saddle and the vehicle frame.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:
The utility model adopts trample the purpose that transmission power to wheel hub forward rotate wheel hub reach bicycle rotate of unidirectional arbor wheel by manpower, and its simplicity of design, volume be less, more lightly, the while can reach people's its intended purposes again easily.

Description of reference numerals: 1, vehicle frame 2, driving wheel 2-1, axle skin 2-2, ratchet 2-3, wheel hub 2-4, ratchet 3, wheel shaft 4, pedal drive mechanism 5, steady wheel 6, control headstock 7, wheel engine device 8, baffle plate 9, saddle 10, recoil spring.
The specific embodiment
As depicted in figs. 1 and 2, a kind of Chainless Bicycle of the utility model, comprise vehicle frame 1 and go up control system, the power system that is provided with, power system comprise the driving wheel 2 that is arranged on the vehicle frame 1, with the wheel shaft 3 bonded assembly pedal drive mechanisms 4 of driving wheel 2, be connected with the steady wheel 5 of its external diameter on the support 1 less than driving wheel.Wherein, driving wheel comprise the axle skin 2-1 that is sheathed on the wheel shaft 3, in be provided with the wheel hub 2-3 of ratchet 2-2, wheel hub 2-3 is sheathed on outside the skin 2-1, the axle skin is provided with the ratchet 2-4 that has spring, and ratchet and ratchet activity clamping are when wheel shaft rotates, axle skin on the wheel shaft also can be along with being driven, ratchet on this moment axle skin can strut by spring, and snaps in the draw-in groove of ratchet and drive wheel hub and rotate, and drives whole wheel rolling.Pedal drive mechanism 4 comprises and is connected in the connecting rod on the wheel shaft and is installed in stretcher on the connecting rod, and steady wheel 5 is arranged on the support at rear of driving wheel.In the present embodiment, the external diameter ratio of the external diameter of steady wheel 5 and driving wheel is 1:5.Control system comprises control headstock 6, the wheel engine device 7 that is positioned at the vehicle frame front end, and the top of driving wheel is equipped with baffle plate 8, and the middle part of vehicle frame is equipped with saddle 9, is provided with recoil spring 10 between saddle and the vehicle frame.The wheel engine device comprises brake control stalk that is installed in control headstock both sides and the brake facing that is arranged on the wheel nave outside, and the brake control stalk is connected with brake facing.
Trample stretcher forward with the both feet circulation take the saddle of this Chainless type bicycle as people after, its stretcher will drive the wheel shaft of driving wheel by connecting rod, axle skin on the wheel shaft also can be along with being driven, ratchet on the axle skin can support by the support of spring to hold and drive the wheel hub rotation in the draw-in groove that will snap in ratchet at this moment, and being the center shaft position of being fixed in tire, wheel hub will rotate along with the power that transmits, this moment, the Chainless type single wheel cycle will advance by the rolling of main tire, and when the people does not think that speed is too fast or slows down, just can not step on stretcher, this moment, the wheel shaft and the axle skin of driving wheel just remained static, and ratchet can continue to rotate forward with coherence power, can press the sour jujube tooth that have spring to shrink back when ratchet rotates this moment, and tire is rotated further thereby main shaft can remain static.
Above-described only is preferred implementation of the present utility model; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
