Abstract

The utility model relates to a bicycle driving device. The device includes: pedals, gears, racks, guide rails, transmission chains, winding devices and driving flywheels. The pedal is connected with the rack, and the rack is installed on the guide rail, and can slide up and down in a straight line; the gear is connected with the driving flywheel, and the chain is wound on the driving flywheel. When stepping on the pedal, the rack slides up and down on the guide track, and through the correct meshing movement with the gear, drives the flywheel to rotate in a circle to realize the forward movement of the bicycle; the winding device drives the rack to return to the guide track to reset, alternately left and right Stepping on the pedal drives the vehicle to move forward continuously at a constant speed. Compared with the traditional bicycle driving device, the bicycle driving device of the utility model converts the up and down reciprocating linear motion of the pedals into the uniform circular motion of the wheel, which is more in line with the motion function of the human body, and is more convenient and labor-saving when riding; and the structure is more stable, and the conversion Higher efficiency can effectively avoid the disadvantages of uneven force application and dead spots in traditional bicycle driving devices; it can be widely used in human-powered driving devices such as cars and boats.

Description

A new type of bicycle driving device

technical field

The invention relates to a human-powered drive device for vehicles, boats, etc., in particular to a novel bicycle drive device.

Background technique

The driving function is a main function of a bicycle. At present, most of the domestic bicycles are driven by a crank and sprocket device. The crank drives the sprocket and drives the rear wheel to rotate, thereby realizing the forward movement of the bicycle. The position of the point needs to be passed through inertia; and the actual work efficiency is not high.

Contents of the invention

The utility model provides a new type of bicycle driving device, which can convert the linear reciprocating motion of a person's up and down stepping on the pedals into a uniform circular motion of the wheel. The structure is more stable, there is no dead point in the working process, and the working efficiency is higher. Stable and labor-saving, comfortable and convenient.

In order to achieve the above purpose, the utility model provides a novel bicycle driving device, which includes: pedals, gears, racks, winding devices, driving flywheels, transmission chains, and is characterized in that rack A and rack B are connected On the guide rail, it can slide up and down in a straight line; rack A and rack B are correspondingly fixed on pedal A and pedal B, and drive the flywheel to rotate by meshing with gear A and gear B respectively. The vehicle moves forward; the rewinding device connects the A rack and the B rack, winds on the frame, and alternately pulls the A pedal and the B pedal to return to the initial position.

Advantages of the utility model

Compared with the traditional bicycle driving device, the bicycle driving device of the utility model has the advantages that the device adopts the movement mode of stepping on the pedal alternately up and down, the torque is always at the maximum value and the force is uniform during the movement process; and the structure is simple, the working state is stable, relatively The traditional crank sprocket drive device has higher working efficiency, and at the same time effectively avoids uneven riding force and dead point position, making riding more comfortable and convenient, and stronger climbing ability.

Detailed ways

As shown in Figure 1, the A rack (3) and the B rack (6) are correspondingly fixed on the A pedal (1) and the B pedal (11), and are connected with the A gear (2) and the B gear respectively. (10) Engage correctly, drive the drive flywheel to rotate, and drive the vehicle forward; alternately pull the A pedal (1) and the B pedal (11) to return to the initial position.

Pedal A 1 and Pedal B 11 are hingedly connected with A rack 2 and B rack 6 respectively, and A rack 2 and B rack 6 are correspondingly connected to the guide rail 4 by sliding left and right, so that they can flexibly move up and down in a straight line, guiding The guide rail 4 is fixed on the vehicle frame; the A rack 2 and the B rack 6 are engaged with the A gear 2 and the B gear 10 respectively to drive the flywheel 8 to rotate; the winding device 5 is connected to the A rack 3 and the B rack 6 , wrapped around the frame. When the A pedal 1 goes down, it correspondingly drives the A rack 3 to slide down on the guide rail 4, and drives the flywheel 8 to rotate through the meshing motion of the rack and pinion, and is driven by the transmission chain 9 wound on the drive flywheel 8. The small flywheel 7 of the rear wheel rotates to drive the vehicle forward. At the same time, the rewinding device 5 is tightened to store energy and drive the B pedal 11 to go upward; when the A pedal goes down to the end and starts to return, step on the B pedal 11 Downward, the rewinding device 5 is loosened to release energy, driving the rack A 3 to slide upward on the guide rail 4, returning to the initial position, and driven by stepping on the pedal in a straight line up and down to realize the continuous rotation of the driving flywheel 8, driving the vehicle forward at a constant speed OK.

This embodiment adopts the driving method of stepping on the pedals up and down, which is more in line with the human body's kinematic function, and more scientifically integrates the functions of transportation, leisure and fitness, and increases the fun of riding; The driving device has a stable structure, higher working efficiency, good promotion value, and can be widely used in human-powered driving devices such as vehicles and ships.
