CN201343123Y - Gear drive two-wheeled vehicle - Google Patents

Abstract

The utility model relates to a gear drive two-wheeled vehicle, and a drive device which connects a power device of the two-wheeled vehicle and a driving wheel is a gear drive device. The gear drive two-wheeled vehicle changes the shortcomings of complicated structure, poor reliability and low drive efficiency caused by using a chain wheel and a chain for drive in the prior art and has the advantages of short drive route, high drive efficiency, reliable use and low fault rate.

Description

The gear transmission two-wheel car

Technical field

The utility model relates generally to a kind of two-wheel car, particularly a kind of gear transmission two-wheel car.

Technical background

Known two-wheel car such as battery-driven car, motor bike, in addition tramp with one's feet step on as the bicycle of power etc. all be with the sprocket chain bar as driving device, to rear drive sprocket, vehicle is advanced power transmission.But above-mentioned sprocket wheel chain gearing is not wear-resistant, breaks easily or damages, and driving efficiency is not high yet, is necessary so known driving device made improvements.

The utility model content

The shortcoming that provides one can overcome known technology is provided the purpose of this utility model, gives between the engine installation of two-wheel car and the drive wheel and provides an efficient height, the failure-free driving device.

For achieving the above object, scheme of the present utility model is: the driving device that connects two-wheel car engine installation and drive wheel is a gear system.

Further scheme is: on the drive wheel of two-wheel car bull gear is installed, a gear train assembly that links to each other with engine installation and the engagement of described bull gear.

Described engine installation comprises manpower driving or electrical motor or combustion engine.

Adopt such scheme, changed the complex structure that uses the sprocket wheel chain gear to be brought in the known technology, poor reliability, the shortcoming that driving efficiency is not high, thus realized the purpose of this utility model.

Below in conjunction with diagram and embodiment scheme is described in more detail.

Description of drawings

The front elevation that Fig. 1 is used as power for the two-wheel vehicle used electrical motor of gear transmission;

Fig. 2 is the bull gear front elevation among Fig. 1;

Fig. 3 is the two-wheel vehicle used ICE-powered front elevation of gear transmission.

Numbering explanation in the diagram:

1 electrical motor, 2 driven gear dishes, 3 toothed disc check screws, 4 rear wheel large gear rings, 5 large gear ring check screws, 6 rear drive sprockets, 7 large gear ring screw holes, 8 explosive motors, 9 engine suspension axis holes, 10 drive gearboxs, 11 driving engine driving gears.

As shown in Figure 1, with electrical motor 1 as power, use the battery traction electrical motor, the rotor of electrical motor 1 and driven gear dish 2 join, driven gear dish 2 and bull gear 4 engagements that are fixed on the rear drive sprocket 6, bull gear 4 is consistent with the center of turn of rear drive sprocket 6, for reaching such engineering factor, the wheel rim of rear drive sprocket is captiveed joint with the bar shaped spoke usually, or makes an integral body, when 2 rotations of the driven gear dish on electrical motor 1 axle head, drive bull gear 4 rotations on the rear drive sprocket.

Figure 2 shows that the constructional drawing of rear wheel bull gear 4, why make gear ring, mainly is handling ease, easy to assembly, saving in material.

Fig. 3 is used as power for two-wheel vehicle used combustion engine, explosive motor 8 is connected with frame by the pivot pin that hangs axis hole 9, why adopt suspension type to connect, be the degree of freedom that increasing combustion engine is installed, the driving gear 11 in axle head on the driving engine 8 and the gear case 10 joins, and the number of gearbox medium gear is determined on a case-by-case basis, output gear that gear case is last and bull gear 4 engagements, transmission drives bull gear 4 by the power that driving engine produced, and rotates thereby drive drive wheel.

Adopt the gear transmission two-wheel car of this programme, drive path is short, and the driving efficiency height uses reliably, and fault rate is low, will be subjected to user's welcome.

Claims (4)

1, a kind of gear transmission two-wheel car is characterized in that: the driving device that connects two-wheel car engine installation and drive wheel is a gear system.

2, a kind of gear transmission two-wheel car according to claim 1 is characterized in that: bull gear (4) is installed, a gear train assembly that links to each other with engine installation and the engagement of described bull gear on the drive wheel of two-wheel car.
