Background technology
At present, known bicycle mainly is the instrument of riding instead of walk.Form by front-wheel, trailing wheel, vehicle frame, sprocket wheel, handlebar, front fork etc.Parts are more, and structure is comparatively complicated, and weight is heavier, is not suitable as the instrument of body-building and amusement.
Summary of the invention
Structure for the reduced proper motion car, expendable weight, the function of riding instead of walk of desalination bicycle, the body-building and the amusement function of increase bicycle, the utility model provides a kind of formula bicycle of directly stepping on, this bicycle structure form is simple, parts are few, very light in weight, multiple version, becoming directly set foot on down motion into the wheel revolutions motion, is the good instrument of body-building and amusement.
The technical solution of the utility model is: this bicycle can be made three kinds of versions, and front and back wheel form, the parallel form of two-wheeled, three-wheel form are now narrated with the parallel form of two-wheeled.Two bending pipes constitute vehicle frame, connect cambered axle in the lower end of bending pipe, in the curved end of cambered axle wheel are installed.Install and fix the sleeve pipe that turns at two bending pipe seats at the nearest place of the two bending pipe first halves.The effective bolted connection of cambered axle and bending, cambered axle upstanding portion are installed pedal, and friction slide plate and spring are then with the adjustment nut locking of adjusting to the right place.The cambered axle curved end is installed the wheel set of being manufactured by metal, and the effect of wheel set is that block bearing and friction produce friction force.Wheel set is provided with friction face, and friction face is located at the one side of wheel, also can be located at the two sides of wheel.Wheel set comprises wheel rim, spoke and wheel hub, and the outer ring of wheel set connects the wheel rim of being made by high-abrasive material, and wheel rim comprises outer ring, spoke and the wheel hub of kiss the earth, and wheel set and wheel rim are installed together, integrant wheel.
Pedal and friction slide plate are at cambered axle upstanding portion up-and-down movement, and moving downward is that pin steps down, and while compression spring, upward movement are that pin leaves the pedal spring reinstatement, the upwards thrust of generation.Have curved groove on cambered axle, the top of curved groove is straight-line groove, and centre portion is a curved groove, and the bottom of curved groove also is a straight-line groove.Friction slide plate up-and-down movement in curved groove breaks away from the wheel set friction face in straight-line groove, contact wheel set friction face in curved groove.The friction slide plate is crooked, along the tangential direction bending of wheel revolutions.The endoporus that friction slide plate and cambered axle cooperate leaves feather key, and feather key slides in the curved groove of cambered axle, does straight-line motion in straight-line groove, does curvilinear motion in curved groove.
Be equipped with friction ball seat and frictin ball on the friction slide plate, the position of friction ball seat is adjustable, adjusts the distance of frictin ball to friction face.Frictin ball is to make of antifriction material, and the friction ball seat has surface groove.Frictin ball moves along with the motion of friction slide plate in friction ball seat surface groove, and when frictin ball touches the wheel set friction face, frictin ball is along the tangential direction of the wheel generation friction moment that rubs downwards, drive wheels rotation.
This bicycle is provided with multiple compression spring, can select for use according to different body weight, different amounts of exercise.
This bicycle has multiple drive form, can stand on the pedal by a pin, and a feet step on the ground is ridden, and can walk on the ground or run to treat that car moves by both feet that both feet are set foot on pedal again, can also be after car move, and both feet remain where one is on pedal and ride.
The front and back wheel form is directly stepped on the formula bicycle, the three-wheel form is directly stepped on the parallel form with two-wheeled of formula bicycle and directly stepped on the formula bicycle, directly steps on the formula frictional transmission, pumping, is transformed into and rotatablely moves, and technical scheme is the same.
The beneficial effect of utility model is: this bicycle is made easily, and low cost of manufacture is flexibly light and handy, safety and stability, and various ways drives, and running is moved, and becomes the wheel revolutions motion, and playing method and operation skill and technique are many, can reach body-building and entertainment purposes.Control entertaining, give the fresh sensation of people, reach the trade-off effect of people's car one with uniqueness.
