Compact drive unit including juxtaposed tracks
First Claim
1. A transport drive unit, including:
- a watertight elongated housing extending along a longitudinal axis and defining an inner chamber, the housing including a top wall and a bottom wall;
two juxtaposed tracks, disposed in parallel around the housing along the longitudinal axis, allowing the drive unit to move when the tracks are driven in rotation around the housing;
at least one track-driving motor, the motor being located in the inner chamber of the housing and including an output shaft that is mechanically connected to at least one of the tracks;
a ventilation circuit for the inner chamber of the housing, the ventilation circuit including an air inlet and an air outlet which communicate with outside of the housing, the ventilation circuit allowing the interior of the inner chamber to be kept above the freezing point when the outside temperature is lower and allowing the interior of the inner chamber to be cooled when its temperature exceeds an upper threshold;
a transport rack located above the tracks and that is connected to the housing; and
a dump body provided on the transport rack.

Abstract
The drive unit includes a watertight elongated housing extending along a longitudinal axis and defining an inner chamber, two juxtaposed tracks disposed around the housing along its longitudinal axis and enabling the drive unit to move when the tracks are rotatably driven around the housing, and at least one track-driving motor. The motor is located within the inner chamber of the housing and includes an output shaft mechanically connected to the corresponding track. The unit can also include a ventilation circuit for the interior of the inner chamber of the housing, and a generator for producing electricity. The drive unit can be manufactured from a single housing or with the housings of two apparatuses that are juxtaposed and rigidly paired.
