Description

The utility model relates to vehicles capable of moving on snow and ice, namely, to the design of snowmobiles with a caterpillar drive.

Known snowmobile (utility model patent No. 91050, IPC B62D 55/00; declared 09/21/2009, published 01/27/2010), containing a tubular frame, an engine, a transmission in the form of a V-belt variator and a gearbox, two support-slewing skis, a caterpillar drive , front and rear suspension, bumper for protection

The disadvantage of the known device is the complexity of the design due to the use of the frame of the tubular structure, leading to an increase in the complexity of the process of manufacturing and assembling a snowmobile.

The closest in technical essence to the claimed device is the IRB1S TUNGUS snowmobile produced by the IRBIS MOTORS Limited Liability Company (IRBIS MOTOROS LLC), which includes a power plant containing an engine installed 180 ° rotated relative to the movement of the snowmobile, a V-belt variator, a reverse gear, a frame of a rigid tubular structure, which is a tunnel, a fuel system, two steerable skis with front suspension, a tracked propeller with a suspension, a bumper, a hood, a seat, a steering system, while the frame of a tubular structure consists of upper and lower longitudinal and transverse elements, and also the struts, between which there is a niche for the power plant in the front part of the frame, while the tubular base of the bracket for attaching the steering shaft is also installed in the front part of the frame, the base for attaching the driver's seat is installed in the middle part of the frame, fastening elements are installed in the rear part of the frame luggage of the second compartment, on the lower longitudinal elements of the middle and rear parts of the frame there are brackets for installing the suspension of the caterpillar propeller (http://irbismotors.ru/tungus, access date 01/18/2021).

The disadvantages of the above design are the duration and complexity of the snowmobile assembly process, due to the relative complexity of the snowmobile design, including:

- the spatial structure of the frame made of a round tube;

- the use of a skis suspension, which is a rigid base in the form of two skis connected to each other (skis);

- execution of the steering shaft in the form of a complex, curved element;

- implementation of the front suspension of controlled skis using a link mechanism and a hydraulic shock absorber;

The use of a spatial frame structure capable of perceiving a system of forces that do not lie in the same plane significantly increases the complexity of assembling a snowmobile due to the need for accurate spatial positioning of frame structural elements relative to each other.

The design of the skid suspension of the caterpillar propeller includes a link mechanism and a hydraulic shock absorber as a damping device, which significantly increases the labor intensity of the assembly process compared to the use of a suspension consisting of rollers fixed on balancers, including coil torsion springs as a damping device.

The complex ski suspension mechanism, including the linkage and hydraulic shock absorber, also increases the complexity of the manufacturing and assembly process of the snowmobile. The use of control skis in the suspension as a spring damping device simplifies the design of the snowmobile while maintaining operational properties.

The technical result, which the utility model aims to achieve, is to simplify the design of the snowmobile while maintaining the operational properties, with a decrease in the labor intensity of the technological process of manufacturing and assembling the snowmobile.

The technical result is achieved by the fact that the snowmobile includes a power plant containing an engine installed rotated 180 ° relative to the movement of the snowmobile, a V-belt variator, a gearbox - reverse, a frame of a rigid tubular structure, which is a tunnel, a fuel system, two steerable skis with front suspension, caterpillar a propeller with a suspension, a bumper, a hood, a seat, a steering system, while the tubular frame consists of upper and lower longitudinal and transverse elements, as well as struts, between which there is a niche for the power plant in the front of the frame, while in the front the frame also has a tubular base of the bracket for attaching the steering shaft, in the middle of the frame there is a base for attaching the driver's seat, in the rear of the frame there are elements for attaching the luggage compartment, on the lower longitudinal elements of the middle and rear parts of the frame there are brackets for installing the suspension of caterpillar movement body. New in the utility model is that the supporting structure of the frame is made flat, capable of taking a load acting only in one specific plane, while the tubular structure of the frame is made of a rectangular shaped tube, the long side of which is set depending on the force of impact.

New in the utility model is that the steering shaft of the column passes between the engine and the reverse gear and is connected by a longitudinal rod with two transverse rods for controlling the rotation of the skis, while the frame consists of two flat trusses - the sidewalls, interconnected by longitudinal and transverse elements from a profile pipes of rectangular cross-section, the suspension of the caterpillar propeller is made in the form of spring-loaded balancers with rollers fixed to them, and the damping element of the suspension of the guided skis is made in the form of a spring.

The implementation of the steering shaft of the column passing between the engine and the reverse gear, connected by a longitudinal rod with two transverse rods for controlling the turn of the skis, allows you to make the steering shaft of a simple geometric shape, which significantly reduces the complexity of the technological process of manufacturing and assembling a snowmobile.

The implementation of the snowmobile frame from two flat trusses - sidewalls, interconnected by longitudinal and transverse elements from a shaped rectangular pipe also reduces the labor intensity of the technological process of manufacturing and assembling a snowmobile due to the simpler joining of rectangular pipes in relation to circular pipes and the use of a plane-space frame structure system ...

The use of a roller suspension in a caterpillar propeller, including coil torsion springs as a damping device, simplifies the labor intensity of the technological process of manufacturing and assembling a snowmobile in comparison with the use of a skid suspension of a caterpillar propeller, which includes a link mechanism and a hydraulic shock absorber as a damping device.

The use of a spring in the suspension of steering skis as a damping device simplifies the design of the snowmobile while maintaining operational properties in comparison with the use of a complex suspension mechanism for steering skis, which includes a link mechanism and a hydraulic shock absorber.
