Snowmobile Chassis

The present invention relates to a chassis for snowmobile maintenance, transport and storage, comprising a chassis and at least three, preferably four, wheels on which the chassis can be moved, at least some of which are pivotable so that the chassis also pivotable, with a support / stopping element at the front of the chassis for a snowmobile to run on the chassis 10

Snowmobiles are heavy and usually cannot be moved by one man, for example, in service or storage areas. Moving, for example, by driving a snowmobile, in turn, causes scratches on the floor due to the carbide slips of the skis. To transport snowmobiles for longer distances, 15 trailers are used, with the sled being driven along a ramp. The trailer is towed with towing advice. This type of trailer is very good but not suitable for moving the carriage in maintenance or storage areas because it is heavy and difficult to handle and also takes up a lot of space.

It is an object of the present invention to provide a new type of carrier for the maintenance, transport and storage of a snowmobile, which enables the above problems to be avoided. The chassis according to the invention is characterized in that the support / stopping member is a bogie pivotally mounted on the chassis frame, about a transverse axis of the chassis, with a pair of wheels at both ends, on which the snowmobile is driven and prevents the carriage from moving too far. With such a platform, the snowmobile can be moved by one

«I

by the only person at the desired location. The snowmobile can also be serviced or simply stored on the chassis.

An embodiment of the invention is characterized in that the chassis frame consists of two transverse beams, one of which is connected to the front wheels and the other to the rear wheels, and a longitudinal joint connecting the transverse beams !!! It shall be fitted with an adjustable longitudinal beam, the front part of which shall be fitted with a support / stop member.

I | Another advantageous embodiment of the invention is characterized by: *: *! that the front wheels of the chassis, which are mainly affected by the weight of the snowmobile, are larger than the rear wheels, which in turn are made freely pivotable.

The invention will now be explained in more detail with reference to the accompanying drawings, in which: Figure 1 shows a substrate according to the invention,

Figure 2 shows a snowmobile run on a chassis according to the invention.

Thus, Figure 1 illustrates a carrier according to the invention for moving, maintaining and storing a snowmobile. The chassis consists of a frame with four wheels 1,2,3 and 4 on which the chassis moves. The front wheels 3, 4 are attached to the frame transverse beam 5 and the rear wheels 1, 2 to the frame transverse beam 6. The front wheels are considerably larger than the rear wheels because they take up most of the weight of the snowmobile. In addition, large front wheels make it easy to handle the substrate on uneven surfaces. With the center of gravity almost entirely on the front wheels and the snowmobile's bow not rising high, the chassis is sturdy and safe in maintenance situations. The front wheels are not pivoting. Instead, the rear wheels are configured to pivot freely, for example in the same manner as in shopping carts, which facilitates the transport of the chassis and carriage in 20 service or similar spaces.

The transverse beams are connected by a longitudinal beam 7 of the frame, which can be made telescopically longitudinally adjustable for snowmobiles of different sizes, for example. The longitudinal beam 7 is formed with a fold point upwards so that the front end of the beam is higher than the rear end. The longitudinal beam 7 is connected to the transverse beams 5, 6 at substantially their longitudinal centers.

At the front of the longitudinal beam 7, near the front wheels 3, 4, is mounted a snowmobile support / stop member 8, which is an axle-swinging bogie with wheels pairs 9, 10 at each end of t1.

The chassis of the invention operates by moving the snowmobile from the rear of the chassis over the rear transverse beam 6 to the chassis. The carriage is driven so far that it comes towards the bogie 8 '', which causes the bogie to stand up and prevent overtaking. The carriage 35 backs slightly backwards and stays firmly on the surface. If necessary, the carriage can be •: 'locked in the chassis, making unauthorized use considerably more difficult.

It will be apparent to one skilled in the art that the invention is not limited to the above embodiment, but may be varied within the scope of the appended claims. The substrate material may be, for example, steel, aluminum or plastic.
