COMPACT PULLING APPARATUS

摘要

The compact pulling apparatus includes a watertight elongated housing extending along a longitudinal axis and a track disposed around the housing along its longitudinal axis. The track enables the apparatus to move when rotatably driven around the housing. Depending on the implementation, the apparatus can include a generator/motor to selectively produce electricity which can power external equipment and rotatably drive the track, and/or a fuel-power engine. The apparatus further includes a power train assembly by which the rotating output power is transmitted from inside to outside the housing by the power train assembly using at least one rotatable shaft section sealingly extending across a corresponding one of the walls of the housing.

1. A compact pulling apparatus including:
a watertight elongated housing extending along a longitudinal axis, the housing including a plurality of exterior walls; a track disposed outside the housing along its longitudinal axis and enabling the apparatus to move when the track is rotatably driven around the housing; at least one track-driving motor for generating rotating output power to move the track, the at least one track-driving motor being longitudinally disposed within the housing; and a power train assembly supported by the housing and establishing a torque-transmitting engagement between the at least one track-driving motor and the track, the power train assembly including:
a main longitudinally-disposed driveshaft located at least partially within the housing;a transversal driving axle; anda gearbox having an input and an output, the input being drivingly connected to the main longitudinally-disposed driveshaft, and the output being drivingly connected to the transversal driving axle; wherein the rotating output power is transmitted from inside to outside the housing by the power train assembly using at least one rotatable shaft section sealingly extending across a corresponding one of the walls of the housing.
