Amphibious vehicle electric drive system

摘要

This invention relates to an amphibious vehicle and especially to an amphibious vehicle having twin internal combustion engines propelling the vehicle in water with a pair of water jet drives and propelling the vehicle on land with one of the same engines having an electric generator powering a pair of electric motors each coupled to a track assembly. Each electric motor and each air brakes are controlled separately to steer and brake the track assemblies.

主权项

1. An amphibious vehicle comprising:
a vehicle hull having a pair of track assemblies, each said track assembly being movable between a raised resting position and a lowered operative position; at least one internal combustion engine mounted in said vehicle hull coupled to a marine transmission driving a water jet drive attached to said vehicle hull for propelling said vehicle hull through water when both said track assemblies are in a raised resting position; an electric generator coupled to and driven by said at least one internal combustion engine; a pair of electric motors powered by said electric generator, one said electric motor coupled to each said track assembly for driving the track assembly to propel said vehicle hull on land when said track assemblies are in a lowered operative position; a disk brake coupled to each said track assembly for selectively braking each said track assembly for braking and steering said vehicle hull; and an electric motor control for remotely controlling each said electric motor to selectively drive each track assembly for propelling and steering said vehicle hull; whereby said amphibious vehicle is propelled in water by said water jet drive powered by said at least one internal combustion engine and propelled on land by said pair of track assemblies coupled to said electric motors and powered by said electric generator.
