Description
Technical field
The utility model belongs to technical field of bicycles, and in particular to a kind of variable force driving bicycle.
Background technique
Bicycle, also known as bicycle or bicycle, the small-sized ground vehicles of usually two wheels, after people rides vehicle, step on foot with foot
Pedal is power, is the environmentally protective vehicles.Bicycle is by vehicle frame, tire, foot-operated, pedal, brake, chain, sprocket wheel
Equal components composition, wherein vehicle frame is the skeleton of bicycle, and the weight for the people and goods that it is born is maximum.According to each component
Work characteristics can substantially be classified as guidance system, drive system, braking system.The drive system of existing ordinary bicycle is
Pedal, pedal be it is fixed, it is both laborious and time consuming in ride.
Utility model content
The purpose of this utility model is to solve the pedal skill both laborious and time consuming in ride of existing bicycle
Art problem provides a kind of variable force driving bicycle.
In order to solve the above technical problems, the technical solution adopted in the utility model is:
A kind of variable force driving bicycle, including bicycle body, it further includes two set casings, pedal, spring and axis
It holds；The axis that the set casing passes through bicycle chainwheel is located at the lower part two sides of vehicle frame in bicycle body；In the set casing
Top is equipped with the upper race rail of arc, is equipped with the lower race rail of arc, the upper race rail and lower race rail in the lower part of the set casing
The center of circle is overlapped, and the upper radius for running rail is less than the lower radius for running rail；The pedal is made of square sleeve and rectangular telescopic arm,
The rectangular telescopic arm covers in square sleeve, and the axis connection of one end of square sleeve and bicycle chainwheel；The bearing is logical
The medial surface that fixing axle is mounted on rectangular telescopic arm one end is crossed, the other end of the rectangular telescopic arm is equipped with foot pedal；The bullet
One end of spring is fixed on square sleeve, and the other end is fixed on the upper of rectangular telescopic arm.
Further, the set casing is circle, and the lower race rail is located at the lower edge of set casing.
Further, the outer surface of the square sleeve is equipped with round protecting crust, and the diameter of protecting crust is greater than admittedly
Determine the diameter of shell.
The beneficial effects of the utility model are:
1, the utility model of simple structure and strong practicability；
2, the pedal of the utility model is scalable, and when foot-treadle, the bearing on telescopic arm one end is along upper race
Rail and the movement of lower race rail, so that the length by adjusting telescopic arm achievees the purpose that laborsaving speed-raising.
3, the round protecting crust greater than set casing is equipped on the outer surface of square sleeve due to the utility model, effectively
Avoid bearing and run rail on pollution of the lubricating oil to clothing trouser legs.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
The partial enlarged view that Fig. 2 is in Fig. 1 I；
Fig. 3 is the scheme of installation of protecting crust in the utility model；
In figure: 1- set casing runs rail on 2-, rail, 4- protecting crust, 5- square sleeve, the rectangular telescopic arm of 6-, 7- bullet is run under 3-
Spring, 8- bearing, 9- bicycle body.
Specific embodiment
As depicted in figs. 1 and 2, a kind of variable force driving bicycle described in the present embodiment, including bicycle body 9, it is also
Including two set casings 1, pedal, spring 7 and bearing 8；The axis that the set casing 1 passes through bicycle chainwheel is located at bicycle sheet
The lower part two sides of vehicle frame in body 9, the set casing 1 are circle；It is equipped with the upper race rail 2 of arc on the top of the set casing 1,
The lower edge of the set casing 1 is equipped with the lower race rail 3 of arc, and the upper rail 2 that runs is overlapped with the lower center of circle for running rail 3, and upper race rail 2
Radius be less than it is lower run rail 3 radius；The pedal is made of square sleeve 5 and rectangular telescopic arm 6, the rectangular telescopic arm
6 sets in square sleeve 5, and the axis connection of one end of square sleeve 5 and bicycle chainwheel；The bearing 8 is pacified by fixing axle
The other end of medial surface mounted in rectangular 6 one end of telescopic arm, the rectangular telescopic arm 6 is equipped with foot pedal；One end of the spring 7
It is fixed on square sleeve 5, the other end is fixed on the upper of rectangular telescopic arm 6.
As shown in figure 3, being equipped with round protecting crust 4 on the outer surface of the square sleeve 5, and the diameter of protecting crust 4
Greater than the diameter of set casing 1, dustproof effect is played, also avoid bearing and runs pollution of the rail to clothing.
The working process of the utility model is as follows:
When firmly stepping on foot pedal moves downward foot pedal, the rectangular bearing 8 stretched on 6 one end of telescopic arm is along upper race rail
2 telemechanicals, pedal shorten；When foot pedal is rotated up, bearing 8 is moved along lower race rail 3, pedal elongation, to reach
The purpose of laborsaving speed-raising.
