Abstract

The utility model relates to the design of all-terrain vehicles and can be used for the design and manufacture of three-wheeled all-terrain vehicles. The technical task aimed at solving the utility model is to increase the cross-country ability of a snowmobile when driving on wooded terrain under conditions of limited front wheel adhesion to the supporting surface. due to the fact that in a known design comprising an engine, transmission, propulsors in the form of two driving wheels at the rear and a non-driving wheel in front of di and the body, located on a common frame, according to a utility model, fenders in the form of triangular metal structures are installed on the all-terrain vehicle frame at the level of the axles of the wheels. The technical result obtained by installing the fenders consists in the possibility of correcting the trajectory of the all-terrain vehicle due to the force interaction of the tree with a moving all-terrain vehicle through an installed chipper and detouring a standing tree without driving a drive wheel over it.

Description

The utility model relates to the design of all-terrain vehicles and can be used for the design and manufacture of a light three-wheeled all-terrain vehicle.

A known design of a light wheeled all-terrain vehicle, consisting of an engine, transmission, propulsors in the form of two driving wheels at the rear and a non-driving steering wheel in front and a body located on a common frame (utility model patent No. 91937, application No. 2009140955 from 05.11.2009).

A disadvantage of the known design is that when an all-terrain vehicle moves through a wooded area, maneuvering between trees, its rear drive wheels can come into contact with trees, run into them, which will lead to dynamic loads on the all-terrain vehicle frame, a possible loss of ability to move and impair patency. When maneuvering between trees, the all-terrain vehicle is rotated by coupling the front steered wheel with the supporting surface. Traction is reduced when loading cargo into the body of an all-terrain vehicle, since the load is usually placed behind the rear axles of the drive wheels. Also, the adhesion strength is significantly reduced when driving on loose snow or when driving on poorly bearing soils. In such conditions, the trajectory of the all-terrain vehicle may be disrupted with the probable collision of one of the driving wheels on a tree.

The technical problem to which the utility model is directed is to increase the cross-country ability of the snowmobile when driving on wooded terrain under conditions of limiting the adhesion of the front wheel to the supporting surface.

This is achieved due to the fact that in the known construction comprising an engine, a transmission, propulsors in the form of two driving wheels at the rear and a non-driving wheel at the front and a body located on a common frame, according to a utility model, fenders in the form of metal are installed on the all-terrain vehicle frame at the level of the axles of the wheels designs of a triangular shape.

The technical result obtained by installing the bumpers consists in the possibility of correcting the trajectory of the all-terrain vehicle due to the force interaction of the tree with the moving all-terrain vehicle through the installed bump and bypassing the standing tree without driving the drive wheel over it.

The device and the principle of construction is illustrated by drawings:

in FIG. 1 is a side view of an all-terrain vehicle;

in FIG. 2 - the same from above.

The all-terrain vehicle consists of an engine 2, a transmission, driving wheels 4, a front steered wheel 6 installed in a fork 5 connected to the frame of the all-terrain vehicle 1, chippers 8, a body 9, a tank 3, and a driver's seat 7. The construction works as follows. When an all-terrain vehicle moves in a wooded area, the torque generated by the engine 2 is transmitted through the transmission to the drive wheels 4. The direction of movement is changed when the front wheel 6 is rotated together with the fork 5 due to the adhesion force of this wheel to the supporting surface. Traction depends on the load on the wheel and the coefficient of adhesion of the wheel to the bearing surface. The load attributable to the front wheel is reduced when placing the cargo in the body 9 of the all-terrain vehicle behind the axis of the drive wheels. It is also possible to reduce the coefficient of adhesion when driving on loose snow or on poorly bearing soils. All of this together can lead to a violation of the desired trajectory of the all-terrain vehicle, the deterioration of its maneuverability and the collision of the drive wheel on a tree. When installing bumpers in violation of the trajectory of the all-terrain vehicle, not the drive wheel, but the bump comes into contact with the tree. The triangular shape of the chipper contributes to the appearance of force upon contact, tending to shift the rear axle of the all-terrain vehicle from the trajectory of its movement of the drive wheel onto a standing tree. Due to this, the cross-country ability of the all-terrain vehicle increases.

The proposed design provides translational motion of the all-terrain vehicle with a possible collision with a standing tree, increases the cross-country ability of the all-terrain vehicle and the speed of the vehicle in comparison with the prototype.
