RIGID PORTABLE TRACK | 1 |
| 20120299370 | CATERPILLAR-TYPE PROPELLING DEVICE FOR A TYRE-BEARING VEHICLE - The invention relates to devices increasing the capacity of vehicles for cross-country travel, and specifically to caterpillar-type propelling devices. The special feature of the caterpillar-type propelling device for a tyre-bearing vehicle, the propelling device containing at least one caterpillar track, the internal surface of which is intended for interaction with the tyres of the vehicle, is that the caterpillar track has limited longitudinal bending internally and provides an internal size of the caterpillar track along the vertical to be greater than the height of the vehicle, and the caterpillar track length is selected to be sufficient to freely encompass the vehicle. The technical result provided by the proposed invention consists in the versatility of use of the propelling device by being capable of being installed virtually on any vehicle without altering and/or modifying the construction of the vehicle. Furthermore, the simplicity of constructing the propelling device, installing the latter on and removing the latter from a vehicle is increased. Furthermore, the proposed propelling device has small dimensions in the dismantled form and is reliable in operation. | 11-29-2012 |
