Abstract

The utility model belongs to an improvement of a driving mechanism of a machinery and pedal dual-purpose vehicle. With a driving chain, the utility model can drive a passive driven chain wheel assembly to engage with the chains fixed on a back wheel rim in order to transmit, so the utility model can conveniently clutch without wearing the tiers. The utility model has the advantages of reasonable structure and low cost, which is suitable for general foot brake or band brake bicycles and is also used as the improvement of the driving mechanism of tricycles and disabled people vehicles.

Description

Transmission with wheel ring

The utility model belongs to the improvement of machine, autocycle driver train.

Have following three kinds in the form that the engine drive transmission is installed on the bicycle at present: 1. the driving engine output wheel drives trailing wheel and travels by the sprocket wheel on the driving chain drive wheel rim central axle sleeve.But output wheel can not separate with follower, thereby requires great effort very much when foot-operated.2. the forward and backward tire of driving engine output wheel direct drive, the transmission of promptly rolling.This type of drive is big to wear on tyres, and the driving process is skidded and thrown switch, and especially winter, more very efficient was low.3. driving engine direct drive trailing wheel cover drives, but complex structure, the cost height.

It is a kind of by the driving engine output wheel that the purpose of this utility model is to provide, and drives chain engages fixing on passive driving messenger chain wheels and the trailing wheel wheel rim by driving chain, carries out transmission.Accomplishing not only can easily the clutch but also the tire that do not wear and tear, rational in infrastructure, the drive transmission device that cost is low.

For better understanding the utility model, be further described below in conjunction with accompanying drawing.

Fig. 1 is assembly drawing, the birds-eye view of the drive wheel loop mechanism after the entrucking.On bicycle rear wheel rim 3, chain geometrical clamp 10 of welding in the middle of a spoke, totally 20.The chain geometrical clamp is fixing with chain 4.With the fixing passive driving chain wheels of forward and backward geometrical clamp 17,18, the minor sprocket 9 in the passive driving chain wheels is connected with driving engine output chain gear 1 by driving chain 2 on chain stay 12, and hinge wheel 6 just is meshed with the chain fixed on the wheel rim.

Fig. 2 is wheel rim chain geometrical clamp and the fixing assembling scheme drawing of wheel rim.Chain 4 is connected on by chain shaft 11 on the bolt 5 of edge chain shaft, and the riveting of chain shaft two is lived, and the bolt string of the edge chain shaft of getting well of will go here and there then, is tightened with nut 13 fixedly in the folder hole at fixing chain again.

Fig. 3 decide bolt clip just, birds-eye view;

Fig. 4 is the positive birds-eye view of chain geometrical clamp;

Fig. 5 be passive driving chain wheels with forward and backward geometrical clamp 17,18 by slide plate 8 just be connected, left view.Passive driving chain wheels are fixed on the slide plate by slide plate bolt of rear end plate 15, and the cylindrical void on the slide plate is connected with preceding geometrical clamp 17 by dowel bolt 20, and forward and backward geometrical clamp 17,18 usefulness bolts 16 are fixed on the chain stay 12.

Fig. 6 be preceding geometrical clamp just, left view.

Fig. 7 be the back geometrical clamp just, left view.

Fig. 8 is the slide plate front elevation.

Fig. 9 is that passive chain wheel set is connected cutaway view with output wheel 1 by messenger chain carriage 7.One end of carriage and semicircle card 28 are contained on the circle footpath that the driving engine mouth do not rotate simultaneously.Carriage can rotate around the output wheel center, adjusts the fixedly clutch of chain 4 on passive chain wheel set and the wheel rim to adapt to.The other end of carriage is with passive driving chain wheels bolt.

It can also be seen that from figure passive driving chain wheels are to be connected by the cat's paw of minor sprocket 9 with hinge wheel, are contained in simultaneously on the chain cover 21 with eccentric shaft 26 and bearing 25, packing ring 27, block gland 22 with jump ring 23 again.

Figure 10 is minor sprocket front elevation and part sectional view.

Figure 11 is hinge wheel front elevation and part sectional view.

Figure 12 is messenger chain carriage front elevation and part sectional view.

Figure 13 be eccentric shaft just, left side view.

Figure 14 is a minor sprocket packing ring cutaway view.

Figure 15 is an axle jump ring front elevation.

Figure 17 is the gland front elevation.

Figure 18 is sprocket wheel cover cutaway view.

Advantages such as the drive wheel loop mechanism that the utility model provides has compact conformation, reasonable, and is easy for installation, the people that can ride bicycle reaches easily and grasps.Bolt 20 before unclamping on the geometrical clamp 17 moves up, and promptly separates fastening nut 19 being driven chain 4 fixing on sprocket wheel and the wheel rim again, just can ride and travel.When the bolt that unclamps geometrical clamp is moved downwards, the chain engages on hinge wheel and the wheel rim can be driven by machine.

The drive wheel loop mechanism that the utility model provides is to general backpedalling brake, and the band-type brake bicycle can be changed system into easily.Can also be applicable to the improvement of the driver train of three-wheel vehicle, car for disabled persons.
