Abstract
The invention belongs to the field of traffic vehicles, relates to a pedal unit without dead angles and solves the dead angle problem of the conventional bicycle pedals. The pedal unit is composed of a chain wheel, a crank, a spring, a shaft sleeve and two pedals. The chain wheel is arranged on one side, on a bicycle, of the crank. Two ends of the crank are provided with the pedals opposite on the same line. The shaft sleeve is arranged in the middle of the crank. One end of the spring is connected to the outside of the shaft sleeve, and the other end of the spring is fixed on the bicycle. Under tension of the horizontal spring, the pedals are in the same plane. During riding, the pedals are stepped downward, and no deal angles occur to the stepping direction, thus labor is saved for the user.
Description
Technical field
Vehicular traffic field belonging to the present invention is a kind of bicycle pedal without dead angle.
Background technology
The current dead angle that there is power thrusts when the pedal of stepping bicycle circles, effort.
Summary of the invention
In order to overcome the current dead angle that there is power thrusts when the pedal of stepping bicycle circles, the deficiency of effort, the invention provides a kind of without dead angle pedal.
The present invention for technical scheme that its technical matters of solution is taked be a kind ofly to be made up of sprocket wheel, bent axle, spring, axle sleeve, two pedals without dead angle pedal.With bent axle while be contained on bicycle body, sprocket wheel is also contained in this on one side, two dress pedal, on the same line, direction is contrary for pedal, dress axle sleeve in the middle of bent axle, linking springs one outside axle sleeve, spring other end is fixed on bicycle body, and spring becomes horizontal, and the pulling force due to spring makes pedal become horizontal all the time.When by bike, pin pedals pedal from the top down, and pedal does not have the dead angle on power thrusts, very laborsaving.
The invention has the beneficial effects as follows, than common foot treading pedal laborsaving, do not have the dead angle on power thrusts all the time, structure is simple.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.，
Accompanying drawing is schematic top plan view of the present invention.
1. pedals (one) in figure, 2. bent axle, 3. sprocket wheel, 4. vehicle body, 5. spring, 6. axle sleeve, 7. pedal (two).
Detailed description of the invention
In the accompanying drawings, bent axle (2) is contained on vehicle body (4), pedal (1) (one) pedal (7) (two) are contained in bent axle (2) two, sprocket wheel (3) is contained on bent axle (2), axle sleeve (6) is contained in the middle of bent axle (2), spring (5) connecting bushings (2), other end is fixed on bicycle body.
Claims (1)
1., without a dead angle pedal, be made up of sprocket wheel, bent axle, spring, axle sleeve, two pedals.It is characterized in that: be contained on bicycle body with bent axle, sprocket wheel is also contained in this on one side, two dress pedal, on the same line, direction is contrary for pedal, dress axle sleeve in the middle of bent axle, linking springs one outside axle sleeve, spring other end is fixed on bicycle body, and spring becomes horizontal.
