Abstract

A double rear wheel relay type drive bicycle is mainly characterized in that a frame adopts a double rear wheel design, two rear wheels which mutually keep proper tyer distances are connected and coaxially pivoted on the rear fork of the frame, the frame is provided with a plurality of drive components consisting of a plurality of drive wheels and drive belt bodies, and the drive components can be driven through a foot-actuated component and synchronously drive the two rear wheels to rotate.

Description

The double rear wheel relay-type drives bicycle

Technical field

The utility model relates to a kind of employing double rear wheel design-calculated bicycle, and coaxial being pivoted in particularly a kind of back vent place at bicycle frame is linked with two rear wheels that keep suitable tire distance each other, divides a word with a hyphen at the end of a line in order to drive vehicle frame.

Background technology

As shown in Figure 1, the bicycle of standard or bicycle all are the designs of single-wheel body before and after adopting, degree of stability when moving in order to improve car body and the comfort level when driving, a lot of automobile friends can consider to choose the bigger tire of wheel width or eliminate and change the narrow tire of width and change the bigger tire of width.

In addition, point out according to research that bicycle is not that everybody is fit to ride, the elderly that muscle strength is relatively poor, reaction is slow slightly should consider to control the higher car money of stability.

As from the foregoing, existing bicycle still has the problem that can improve again as above-mentioned, does not provide actv. solution and means but see relevant dealer for a long time.

Summary of the invention

In view of this, main purpose of the present utility model promptly is to provide a kind of and can improves the degree of stability when driving and the bicycle of comfort level.

For reaching above-mentioned purpose, the utility model proposes a kind of double rear wheel relay-type and drive bicycle, be that mainly vehicle frame adopts the double rear wheel design, it includes:

One vehicle frame has a front fork and a back vent;

One front vehicle wheel is hubbed at this front fork;

Two rear wheels, coaxial this back vent that is hubbed at; And

One driving system includes and is located at a foot-operated assembly of one on this vehicle frame and a driven unit; Wherein, one second power wheel that this driven unit has one first power wheel accepting this foot-operated assembly and drive, links by one first transmission belt body and this first power wheel, with one the 3rd power wheel of the coaxial connection of this second power wheel, and with coaxial connection of two rear wheels and one the 4th power wheel that links by one second transmission belt body and the 3rd power wheel.

The better one, two rear wheels that are hubbed at this back vent keep a tire distance each other.

The better one, the 3rd power wheel and the 4th power wheel are arranged between two rear wheels.

The better one, this first power wheel, this second power wheel, the 3rd power wheel and the 4th power wheel are all gear, and this first transmission belt body and the second transmission belt body are all chain.Rely on above-mentioned formation, the utility model is the bicycle that a kind of double rear wheel drives, the design of possessing suitable tire distance by two rear wheels each other, degree of stability when moving and the comfort level when driving except improving car body, simultaneously also can utilize double rear wheel to keep standing, must not be dependent on support foot rest.

The specific embodiment

Relevant technology contents of the present utility model and detailed description now cooperate graphic being described as follows:

Please consult Fig. 2 and shown in Figure 3 simultaneously, the bicycle of double rear wheel of the present utility model includes a vehicle frame 10, vehicle frame 10 rear and front ends are pivoted with tire respectively, and include bicycle basic indispensable functional structure and accessory, for example seat cushion, handgrip, braking system or the like.

Vehicle frame 10 has uses a front fork 11 and a back vent 12 that is pivoted and connects for tire, wherein, be pivoted with a front vehicle wheel 21 at the front fork place, and the back vent place is pivoted with two rear wheels 22,23.Simultaneously, on vehicle frame 10, be equipped with in order to drive the driving system 30 that double

rear wheel

22,23 rotates, driving system 30 includes is located at a foot-operated assembly 31 of one on the vehicle frame 10 and a driven unit 32, foot-operated assembly 31 includes to be pivoted by crank 312 and is linked to pedal 311 on the vehicle frame 10, tramples for the rider.

As for 32 of driven units be one second power wheel 322 that has one first power wheel 321 accepting foot-operated assembly 31 and drive, link by the one first transmission belt body 325 and first power wheel 321, with one the 3rd power wheel 323 of second power wheel, 322 coaxial connections, and with two

rear wheel

22,23 coaxial connections and pass through one second transmission belt body 326 and one the 4th power wheel 324 that the 3rd power wheel 323 links.

Constitute whereby, when the rider trampled foot-operated assembly 31 rotations, double

rear wheel

22,23 can drive and rotation synchronously via driven unit 32, divides a word with a hyphen at the end of a line to drive vehicle frame 10.More particularly, can order about 321 rotations of first power wheel during rider's pushes pedals 311 synchronously, consequently second power wheel 322 that links by the first transmission belt body 325 also can be driven simultaneously and rotate, and force the 3rd power wheel 323 to be driven to rotate in the lump, then allow the 4th power wheel 324 that links by the second transmission belt body 326 also rotate synchronously, order about two

rear wheels

22,23 rotations with the 324 coaxial connections of the 4th power wheel.In brief, driven unit 32 is to drive two

rear wheel

22,23 runnings by two groups of structure designs by two power wheels and transmission belt body.

Wherein, two rear wheels keep a tire apart from d each other, and the 3rd power wheel 323 and the 4th power wheel 324 are arranged on the position between two rear wheels 22,23.In addition, first power wheel 321, second power wheel 322, the 3rd power wheel 323 and the 4th power wheel 324 that this enforcement disclosed are all gear, and the first transmission belt body 325 and the second transmission belt body 326 then are all chain.

When implementing, the power wheel quantity in the driven unit 32 and the position of configuration all can cooperate vehicle frame 10 patterns to be adjusted and change; In addition, the power wheel that comprises of driven unit 32 and the transmission belt body design that also can adopt belt pulley and belt.

As seen from the above description, the utility model is a kind of novel bicycle design that double rear wheel drives that has, adopt single rear wheel design-calculated bicycle compared to tradition, the innovative design of double rear wheel not only can increase the width that lands, degree of stability when improving car body and moving and the comfort level when driving can utilize double rear wheel to keep standing simultaneously.

The above person only, it only is preferred embodiment of the present utility model, when not limiting the scope that the utility model is implemented with this, so the change of numerical value or displacement of equivalent elements such as, or, all should still belong to the category that the utility model patent contains according to equalization variation and modification that the utility model claim is done.
