Description

The utility model relates to vehicles capable of traveling on snow and ice, in particular to self-propelled collapsible devices with a caterpillar mover, in particular, to collapsible single-track snowmobiles.

Known snowmobile, protected by patent for invention No. 2424150. The snowmobile contains a frame, an engine, a seat, a steering, a front support, a rear support mounted on a frame connected to the frame. The indicated elements of the snowmobile are combined into three independent modules: the front support module, the frame module, the rear support module, articulated and detachable.

The disadvantages of this snowmobile include the complexity of the design and its assembly, unreliability due to the presence of several connections of the main nodes.

Known snowmobile, protected by a patent for utility model No. 77839. The snowmobile includes steering, a power unit and a caterpillar mover, is equipped with two guide skis and made in the form of a transformer, moreover, the connection of the power unit to the main frame, the connection of the ski guides to the power unit and the seat on the main frame are made using quick couplings and the chain tensioner is floating .

The disadvantages of this snowmobile are that it has a complex structure, large dimensions and heavy weight.

Closest to the proposed utility model by structural features is a snowmobile protected by RF patent for utility model No. 95631. The snowmobile contains a frame with an engine mounted on it, a steering wheel with a control mechanism, a main frame on which a track mover is mounted, two guide skis made flat-convex, all-metal, mounted on the transverse beam of the control mechanism, a trailer made in the form of a transformer, , the new one is that the snowmobile contains a carrier ski, the engine occupies an asymmetrical front location relative to the longitudinal axis of the snowmobile, the transmission uses an automatic centrifugal clutch e "dry type", and the caterpillar mover made by the type of "caterpillar around the ski" contains spikes in the caterpillar mover.

The disadvantage of this device is the design complexity, the use of an automatic dry-type centrifugal clutch, a chain gear with a gear block on the intermediate shaft, which requires constant adjustments to the chain gear of the intermediate gear. In addition, the snowmobile has a lot of weight.

The objective of the invention is to provide a snowmobile more reliable in operation, easy to maintain, collapsible, compact in design, with a low weight of units.

The problem is solved in that in the well-known snowmobile, including a frame, an engine, a control mechanism, a mover made by the type of “caterpillar around the ski”, according to the proposed utility model, the snowmobile has two supports combined in two blocks: a motor unit comprising two steered skis with a control mechanism, the frame of the motor block with a fixed frame, on which the sliding frame of the engine mount with the chain tension screw and the chain tension lock is placed, while the engine, with a reduction gear and an automatic circuit The oil bath is designed as a single unit, from the output shaft of which, through a chain drive, rotation is transmitted to the drive shaft of the caterpillar unit, a detachable baffle-sealant and a caterpillar unit including a caterpillar unit frame, on which it is rigidly mounted, are mounted on the frame of the motor unit a subframe is mounted in which a support ski is installed from a set of pipes a

also a drive shaft with caterpillar drive stars, a driven chain drive star, a driven shaft with rollers and a caterpillar, support skis are made of plastic with steel undercuts, while the frame of the motor block is provided with fingers, and the track frame is equipped with bushings for accommodating fingers, the connection is screwed clamps; the frame of the caterpillar block provides for the placement of the seat, trunk and tow bar

Justification of the benefits that give new signs:

The use of automatic disk clutch with a reduction gear in an oil bath eliminates the presence of an intermediate shaft of a chain drive, which increases the reliability and safety of the structure.

The ability to remove the engine and the removable steering wheel from the frame of the motor unit without disconnecting the gas cable and the electrical wiring improves access and maintenance of the engine. Separation of units facilitates weight and transportation of units.

- The use of plastic skis with steel undercuts, reduces weight and improves handling,

In general, the advantage of the proposed design is the reliability in operation and ease of maintenance of a collapsible, compact in design device with a small weight of units.

The description of the device is illustrated in figures 1, 2 and 3.

The motor block includes a frame (1), a fixed frame (2), in which the sliding engine mount (3) moves with the chain tension screw (4) and the clamp (5). An engine (6) is mounted on the sliding support (3), with a gearbox and an automatic clutch made in the form of a single unit. From the output shaft of the automatic clutch, through a chain transmission, rotation is transmitted to the drive shaft of the track unit.

A control mechanism is also located on the frame of the motor block, which consists of a quick-detachable steering wheel (7), with a screw (8), a steering rack (9), steering rods (10), and a pivot device (11). Two steered skis (12) are the front support, the role of the rear support is performed by the tracked track ski 17.

A removable chipper-seal (13) and a headlight (14) are mounted on the frame of the motor block.

The caterpillar block consists of a caterpillar block frame (15), a subframe (16), in which a support ski is installed from a set of pipes (17), is attached to the caterpillar block frame (15) by welding and with the frame mounted

drive shaft (18) with caterpillar drive stars, driven chain drive star (19), driven shaft with rollers (20) and caterpillar (21), form the “caterpillar around ski” mover.

On the frame of the caterpillar block (15) there is a seat (22), a trunk (23) and a tow bar (24).

The caterpillar block frame is equipped with fastening means: bushings (26) and screw clamps (27).

The caterpillar motor block is connected by means of the fingers (25) of the frame of the motor block, the bushings (26) of the caterpillar block and the clamps (27).

Arriving at the place of operation, the snowmobile is disassembled, removed from the vehicle, assembled using the fingers of the motor and bushes with screw locks of the caterpillar blocks, the engine and the removable steering wheel are mounted on the frame of the motor block, the chain is tensioned with a screw and the chain tension lock, and a removable chipper is installed - gasket, install the seat and trunk The driver sits on a removable seat, which is fixed on the track unit.

The snowmobile uses a 4-stroke gasoline engine with a displacement of up to 200 cm3. From the engine, through an automatic disk centrifugal clutch with a reduction gear in the oil bath, which is triggered by an increase in the engine speed, the torque is transmitted to the driving star of the output shaft of the reduction gear, then to the driven chain drive star on the drive shaft of the track unit, and located on the shaft rubber-fabric leading stars mesh with track tracks and drive the snowmobile.
