ASSEMBLY FOR MOVEMENT OF TRANSPORT VEHICLES ON SNOW Russian patent published in 2011 - IPC B62D55/04 B62D55/65 

FIELD: transport.

SUBSTANCE: inventions refer to transport vehicle building industry. Transforming assembly of transport vehicle for movement on snow, which stands for wheel of wheeled transport vehicle, includes drive mechanism which interacts with drive shaft of transport vehicle, endless belt brought into action with drive mechanism. Belt passes above horizontal plate to provide support surface on snow. Assembly for movement on snow includes frame supporting two load-carrying wheels, the above load-carrying wheels located at some distance from each other, which is bigger than their combined radii, caterpillar thread endlessly contacting snow is installed for rotation on the above load-carrying wheels the surface contacting with caterpillar thread provided between lower end sections of the above load-carrying wheels. Setting of width of caterpillar thread and surface contacting the caterpillar thread result in the transport vehicle having force impact of less than 250 kg/square metre. All-wheel drive vehicle in which each of 4 wheels is replaced with one above mentioned assembly. Front pair of assemblies is controlled with hydraulic actuator, and rear pair is optionally controlled with hydraulic actuator.

EFFECT: versatility of transport vehicle is achieved.
