Abstract

A power traction wheel carrier comprises a stand bar (1), a shaft support (2), a power wheel (3), and a handle bar (4), wherein the handle bar (4) is fixed at the top end of the stand bar (1), the lower end of the stand bar (1) is fixedly connected with middle of the shaft support (2), and the shaft of the power wheel is fixed at the two ends of the shaft support (2) and perpendicular to the stand bar (1). The power traction wheel can be conveniently installed on small-sized wheelchair or various small-volume vehicles that need manual push. The power traction wheel carrier can pull relatively heavier object through relatively small propelling power, and can be separately dismounted. It has the advantages of safe and convenient use, and convenience for carrying.

Description

A kind of power traction wheel carrier

One, technical field:

The utility model relates to a kind of dynamic traction device mechanism, specifically designs a kind of two-wheel traction wheel carrier.

Two, technical background:

At present, the general-duty vehicle for disabled individuals is divided into two kinds on the market.A kind of for taking turns chair form, the user moves vehicle by the major diameter support wheel that rotates the wheelchair left and right sides, another kind is the three-wheel vehicle of chain gear, the disabled person rotates the driving gear wheel by the handle of the chain gear of a pair of analog bicycle stretcher, then driving gear with power through 2 and the wheel chain transmission be transferred to the power wheel of vehicle, more than two kinds of power transmission modes all have defective.First kind of wheel chair form is because its left and right sides major diameter support wheel and frictional ground force are bigger, so the people of older particularly arm strength weakness be difficult to realize this support wheel of rotation freely, and use electronic or other propulsions source to increase the cost of whole wheel as the takeoff output of wheelchair.General aged family is difficult to burden, and the wheelchair pot life system of electronic classification is more, be not suitable for general needs at home, what another kind of tricycle for disabled people used is the chain drive of a kind bicycle, but because so it need be bigger the manually operated height entire mechanism of the people volume that clutch end improves, thereby increased whole vehicle volume, this tricycle for disabled people generally can only be as the outdoor vehicle of long distance, and just very inconvenient when some narrow road sections or indoor use.

Three, summary of the invention:

The purpose of this utility model provides and a kind ofly new easy manually be the traction wheel carrier of power, can be installed in easily on the small-sized wheelchair, on the vehicle of the artificial promotion of needs that perhaps various volumes are little.This kind hand traction wheel carrier can reach the relatively large object of trailing weight by less propelling thrust, safe and convenient to use, and can disassemble separately and carry, can be installed in the elderly easily is used as the tractor of wheelchair or needs in the artificial heavier small-sized go-cart that promotes, this kind power traction wheel carrier has very strong self-locking performance, when being mounted vehicle and being in the slope, very safety labor-saving vehicle is driven avoided making the uncontrollable consequence of vehicle because of resistance that inclination of vehicle produces or sliding force.

The utility model is a kind of power traction wheel carrier, described power traction wheel carrier comprises strut bar 1, bracing strut 2, power wheel 3 and handlebar 4, its improvements are, described handlebar 4 is fixed on the top of strut bar 1, strut bar 1 lower end is connected with the center fixed of bracing strut 2, the axle of described power wheel is fixed on the two ends of bracing strut 2,1 one-tenth spatial vertical of axletree place straight line and described strut bar of described power wheel 3.

The optimal technical scheme that the utility model provides is that described bracing strut 2 comprises crossbeam 2A, bracing strut 2B and bracing strut 2C, described crossbeam 2A goes up even distance slot is set, and bracing strut 2B and bracing strut 2C are by the slot clamping on pin card and the crossbeam 2A, and described strut bar 1 lower end is equipped with stretcher.Described strut bar is installed with connecting interface on (1).

A kind of more preferably technical scheme that the utility model provides is that described power traction wheel carrier can be connected with the wheelchair that has support wheel, and described power traction wheel carrier can be connected with the go-cart support.

A kind of most preferred technique scheme that the utility model provides is that its direct of travel of vehicle of described power traction wheel carrier has been installed is opposite with the opening direction of bracing strut 2.

Four, description of drawings:

Below in conjunction with accompanying drawing the utility model is elaborated:

1 Fig. 1 is the main diagrammatic sketch of a kind of power traction wheel carrier of the utility model;

1 is that strut bar, 2 is that bracing strut, 3 is that power wheel and 4 is handlebar among the figure, and 5 are and the car body splicing interface.

2 Fig. 2 are the side diagrammatic sketch of a kind of power traction wheel carrier of the utility model:

3 Fig. 3 are the main diagrammatic sketch of a kind of power traction wheel carrier of the utility model with the wheelchair assembling;

4 Fig. 4 are the main diagrammatic sketch of a kind of power traction wheel carrier of the utility model with four-wheel go-cart assembling.

Five, the specific embodiment:

This power traction wheel carrier that the utility model provides is particularly suitable for the dilly that short-distance and medium-distance need manpower to promote, wheelchair for example, waggon.Introduce embodiment of the present utility model below in conjunction with accompanying drawing.

Fig. 1 is the main diagrammatic sketch of described power traction wheel carrier.

As can see from Figure 1: the utility model comprises strut bar (1), bracing strut (2), power wheel (3) and handlebar (4), described bracing strut (2) comprises crossbeam (2A), on scalable bracing strut (2B) and axletree support (2C) crossbeam (2A) equidistant socket is set, scalable bracing strut (2B) is by a bayonet lock, screens is fixed on the crossbeam (2A), scalable bracing strut (2B) can be gone up at crossbeam (2A) and move when bayonet lock is pulled out, and regulates the distance between two power wheels.

When the distance between two power wheels was big, the power traction frame can obtain bigger miles of relative movement during by the lateral rotation handlebar.Equaled to improve the gait of march of the car body that drawbar frame drove, but the swing of car body is also very big simultaneously, motion path becomes S shape.Distance between power wheel hour can obtain less miles of relative movement by the lateral rotation handlebar, but the power traction frame can produce bigger tractive force.Be suitable for driving when vehicle load is big.

Axletree support (2C) is to captive joint with the power wheel shaft, axletree support (2C) not with support stalk in same plane, and the opening direction of axletree support (2C) is opposite with the working direction of power traction frame.

Can not disassemble by the communication port of itself and car body when the power traction frame does not use, car opinion bracing strut (2B) is designed to folding physical construction with axletree support (2C).When the power traction frame does not use, the overlapping of wheel invagination can be risen.
