Abstract
The utility model relates to an improved four-wheel drive small handcart which comprises a small handcart body and is characterized in that two front wheels and two rear wheels are arranged at the bottom of the small handcart body; transmission wheels are arranged between the front wheels and the rear wheels; small wheel casings are arranged outside the transmission wheels and are fixed on the small handcart body; fixed rods are fixed at the lower ends of the small wheel casings; separation blades are further fixed on the fixed rods which are positioned at the lower ends of the transmission wheels; and the separation blades are positioned at the outer sides of the transmission wheels. The improved four-wheel drive small handcart has the advantages that the small handcart can easily move forward as the rear wheels run synchronously with the front wheels so as to input forwarding power when the front wheels slips off, so that the use efficiency is greatly improved under severe environment, the transmission shafts drive the front wheels to rotate, the transmission wheels can be driven while the front wheels rotate, the rear wheels can be driven to rotate through friction when the transmission wheels rotate, thereby realizing simultaneous forwarding and backing of the four wheels forward and backward walking.
Description
Technical field
The utility model relates to a kind of waggon, relates in particular to a kind of improved four wheel drive waggon.
Background technology
Waggon in the market all is Two-wheeled, when two wheels in front are walked, when running into higher sloping of the gradient, hill climbing ability is relatively poor, the easy front-wheel of road skids and does not walk, and front-wheel is got down hopeless in a quagmire and can't be walked once load, causes the service efficiency degradation, for addressing the above problem, the spy provides a kind of new technical scheme.
The utility model content
The purpose of this utility model provides a kind of improved four wheel drive waggon.
The technical solution adopted in the utility model is:
A kind of improved four wheel drive waggon, comprise the waggon body, described waggon body bottom is provided with two front-wheels and two trailing wheels, be provided with power wheel between described front-wheel and the trailing wheel, described power wheel outside is provided with little wheel cover, and described little wheel cover is fixed on the waggon body, described steamboat cover lower end is fixed with fixed link, also be fixed with catch on the described fixed link, described fixed link is positioned at the power wheel lower end, and described catch is positioned at the power wheel outside.
The utility model has the advantages that: front-wheel is when skidding, because trailing wheel and its synchronized operation, can be to its input power forward, just be easy to move on, greatly improved service efficiency under rugged environment, transmission shaft drives front-wheel and rotates, front-wheel can drive power wheel and rotate when rotating, the power wheel rotation can drive trailing wheel by friction and rotate together, and 4 wheels of walking advance simultaneously, retreat before and after just having realized, thereby realizes four wheel drive.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of front-wheel, trailing wheel and power wheel among Fig. 1.
Wherein: 1, waggon body, 2, front-wheel, 3, trailing wheel, 4, power wheel, 5, little wheel cover, 6, fixed link, 7, catch.
The specific embodiment
As depicted in figs. 1 and 2, a kind of improved four wheel drive waggon of the present utility model, comprise waggon body 1, waggon body 1 bottom is provided with two front-wheels 2 and two trailing wheels 3, is provided with power wheel 4 between front-wheel 2 and the trailing wheel 3, power wheel 4 outsides are provided with steamboat cover 5, steamboat cover 5 is fixed on the waggon body 1, and steamboat cover 5 lower ends are fixed with fixed link 6, also is fixed with catch 7 on the fixed link 6, fixed link 6 is positioned at power wheel 4 lower ends, and catch 7 is positioned at power wheel 4 outsides.
The utility model has the advantages that: front-wheel is when skidding, because trailing wheel and its synchronized operation, can be to its input power forward, just be easy to move on, greatly improved service efficiency under rugged environment, transmission shaft drives front-wheel and rotates, front-wheel can drive power wheel and rotate when rotating, the power wheel rotation can drive trailing wheel by friction and rotate together, and 4 wheels of walking advance simultaneously, retreat before and after just having realized, thereby realizes four wheel drive.
