Benefits of technology

[0004]According to the present invention, a miniature gasoline engine is installed at the rear section of the model car, which provides a reasonable center of gravity to the model car and therefore a reliable operation. The transmission assembly is configured such that the main transmission axle runs axially through the model car and directly drives the two front wheels and the two rear wheels, respectively, through the couplings, front and rear differentials, and the suspension systems.

Problems solved by technology

However, for bumpy or steep surfaces, their performance and reliability are less than satisfactory.
In addition, these rear-wheel driven model cars are slower and more difficult to control.

Embodiment Construction

[0010]The following descriptions are exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.

[0011]FIG. 1 is a schematic diagram showing the transmission assembly of a four-wheel drive model car of the present invention. A first transmission gear 1 shown in the diagram is connected to and driven by the axle of a miniature gasoline engine (not shown). The transmission gear 1 in turn engages a parallel, second transmission gear 2 which is mounted at an end of a first transmission axle (not numbered) for speed reduction. A first bevel gear 3 is provided at the other end of the first transmissi...

Abstract

A miniature gasoline engine is installed at the rear section of the model car. A first transmission gear is connected to and driven by the axle of the miniature gasoline engine, which in turn engages a parallel, second transmission gear, which is mounted at an end of a first transmission axle. A first bevel gear is provided at the other end of the first transmission axle, which engages a perpendicular, second bevel gear. The second bevel gear is connected to a center differential located in the center of the model car which in turn drives a second transmission axle (i.e., the main transmission axle). The second transmission axle runs through the center differential and axially through the model car, and directly drives the two front wheels and the two rear wheels, respectively.

Description

TECHNICAL FIELD OF THE INVENTION[0001]The present invention generally relates to model cars, and more particularly to a model car having a four-wheel driving system.DESCRIPTION OF THE PRIOR ART[0002]Existing remote-control model cars have their rear wheels driven by a miniature gasoline engine. The front wheels on the other hand are connected to the steering mechanism of the model car for direction control. These remote-control model cars are simple to manufacture and operate rather smoothly over flat surfaces. However, for bumpy or steep surfaces, their performance and reliability are less than satisfactory. In addition, these rear-wheel driven model cars are slower and more difficult to control.SUMMARY OF THE INVENTION[0003]As such, a four-wheel drive model car is provided herein to overcome the disadvantages of the prior arts.[0004]According to the present invention, a miniature gasoline engine is installed at the rear section of the model car, which provides a reasonable center ...
