Problems solved by technology

In addition, for a slope with a large slope, the driving force of a single driving wheel is small, and it is difficult to go uphill
Some bicycles with front-drive function have complex structures, and some have inconvenient front-rear drive switching

Embodiment 1

[0032] See attached Figure 1-7 , a dual-drive bicycle with a variable front-drive structure, mainly comprising a vehicle frame 14, front and rear wheels, a vehicle seat, and a pedal 15; , the pedal 15 is installed under the vehicle seat, the pedal 15 can drive the sprocket, and the flywheel of the rear wheel is driven by the chain; it is characterized in that: the top of the front end of the vehicle frame 14 is connected with a cylinder 1 through a cross bar 13, and the cross bar 13 and the cylinder 1 Tighten in the form of buckles; relative movement and rotation are not allowed; the front end of the frame 14 is provided with a T-shaped cylinder 5, and the frame 14 and the T-shaped cylinder 5 are tightened in the form of buckles, so that relative movement and rotation cannot occur ; There is a primary transmission device 4 between the left side of the cylinder 1 and the T-shaped cylinder 5; a secondary transmission device 8 is provided between the right side of the T-shaped c...

Embodiment 2

[0036] Different from Embodiment 1, a locking mechanism is provided between the right crank 3 and the cylinder 1; the locking mechanism includes a locking cylinder 9, a slider 10 and a spline 11, wherein the locking cylinder 9 and The cylinder 1 is fixedly connected by screws; the inside of the locking cylinder 9 is provided with a chute, the spline 11 is fixedly connected with the right crank 3 by welding, the right side of the slider 10 is provided with a spline groove to cooperate with the spline 11, and the slider The left side of 10 is provided with boss and chute to cooperate, and the cooperation between the boss on slide block 10 left side and locking cylinder 9 chutes has damping existence, can not slide by oneself.

[0037] When using the rear drive mode, the slider 10 moves to the spline 11, the spline groove on the right side of the slider 10 cooperates with the spline 11, and the boss on the left side of the slider 10 cooperates with the chute of the locking cylinde...

Abstract

The invention discloses a double-drive bicycle with a variable front drive structure, and belongs to the technical field of bicycles. The bicycle mainly comprises a frame (14), a front wheel, a rear wheel, a saddle and pedals (15). The bicycle is characterized in that the upper part of the front end of the frame (14) is connected with a cylinder (1) through a cross rod (13); a T-shaped cylinder (5) is arranged at the front end of the frame (14); a primary transmission device (4) is arranged between the left side of the cylinder (1) and the T-shaped cylinder (5); and a secondary transmission device (8) is arranged between the right side of the T-shaped cylinder (5) and the front wheel hub. The front wheel drive and the rear wheel drive can be carried out at the same time and can also be carried out independently, lactic acid released by anaerobic movement in the riding process is avoided, and the drive capacity and practicability of the bicycle are greatly improved.

Description

technical field [0001] The experimental model relates to the technical field of bicycles, in particular to a dual-drive bicycle with a variable front-drive structure. Background technique [0002] As the country pays more and more attention to the ecological environment, more and more people respect the low-carbon travel mode of transportation. Among them, as a green and low-carbon travel tool, more people are willing to choose it as a travel tool. As a travel tool, bicycles not only save energy and reduce emissions, but also exercise. Most of the bicycles sold on the market are driven by a chain, the rear wheel is used as a single drive wheel, and the front wheel is used as a guide wheel with a single function. For cyclists who like to ride outdoors, how to preserve their physical strength is particularly important. Long-term anaerobic exercise can also cause lactic acid, making their leg muscles sore. In addition, for a hill with a steep slope, the driving force of a s...
