DESCRIPTION:
BRIEF SUMMARY
The object of the invention is a chassis structure of a vehicle or a working machine, to which belong the axles of the wheels connected with the frame of the vehicle or the working machine, which are articulated to the frame in such a way, that the wheels have been arranged mobile in the height direction of the vehicle.
When driving with vehicles or working machines on an uneven surface such as in a terrain or on a road of a very bad condition the vehicles and working machines sway when their wheels hit the rises and depressions of the earth surface, whereby the driving of them is troublesome and their handling characteristics are poor. The axles of the wheels can be fastened articulated to the frame of the vehicle, whereby the weight will be divided evenly. When moving on an uneven surface the vehicles and working machines should be steered in the most efficient way and using the smallest possible turning radius, but off-the-road vehicles and working machines are troublesome to steer in a limited space.
The aim of the invention is to bring forward the chassis structure of the vehicle or working machine, by which better handling charcteristics compared with the known structures are achieved when driving on an uneven surface. Additionally, the aim of the invention is to bring forward a chassis structure, with the help of which the vehicles and working machines can be steered efficiently in the wished direction. Further the aim of the invention is to bring forward the chassis structure, which is easy to use and dependable.
The aim of the invention is achieved by means of the chassis structure,
According to the invention the axles of the vehicle or the working machine are connected to the frame of the vehicle or the working machine through the intermediation of fastening organs, favourably ball-and-socket joints placed on the opposed sides of the axles, to be moved in the length direction of the vehicle in regard of the connection spot. The axles are favourably ordinary rigid axles or other axles suitable for the purpose. The fastening organs make possible the mobile articulation of the axles and the moving of the wheels as well in the height as the length direction of the vehicle or the working machine either separately or simultaneously, e.g. when the wheels move in the height direction of the vehicle in accordance with the uneveness of the terrain and they are turned for steering of the vehicle. The fastening organs are placed on the opposite to the each other, whereby the connecting of the axle to the frame is easy.
The vehicle of the working machine can easily be equipped with a regulating device of the side declination, such as a manually operated or an automatic regulating device of the gyro horizon. In biaxial vehicles both axles can be tractive without differential intermediate gears, which is advantageous both in traction and in braking. The chassis structure in accordance with the invention is suitable for use in all vehicles and working machines, such as e.g. tractors, loaders, workers machine chassis, towed objects and corresponding. With the help of that the vehicle or the working machine can be steered with a very small turning radius or even transferred sidewise in certain applications. Due to the chassis structure the vehicle or working machine can be steered very efficiently in all kinds of terrain conditions and simultaneously preserve the efficiency and the grip of the wheels of the vehicle or the working machine, because all the wheels are pressed against the earth in all terrain conditions with the same force.
In the following the invention is explained more in detail by referring to the attached drawing, where
