Abstract

A large electric vehicle with a detachable high voltage isolation structure is provided. Due to the detachable high voltage isolation structure, the drawbacks of repairing the high voltage components of the large electric vehicle will be overcome. All of the high voltage components are integrated into the detachable high voltage isolation structure. Consequently, the maintenance worker can repair the large electric vehicle in a safe environment.

Claims

a chassis;

the detachable high voltage isolation structure connected with the chassis;

an axel assembly installed on the chassis, and comprising a differential mechanism and an axel;

a power motor disposed within the detachable high voltage isolation structure for driving the vehicle structure;

a detachable transmission shaft, wherein the differential mechanism and the power motor are connected with each other through the detachable transmission shaft;

a supplemental steering pump disposed on the chassis for providing hydraulic oil to a steering system;

a supplemental steering motor disposed within the detachable high voltage isolation structure for driving the supplemental steering pump;

a detachable supplemental steering pump connector, wherein the supplemental steering motor and the supplemental steering pump are connected with each other through the detachable supplemental steering pump connector;

an air-conditioning compressor disposed within the detachable high voltage isolation structure for generating ice water;

an air-conditioning motor disposed within the detachable high voltage isolation structure for driving the air-conditioning compressor;

a detachable pipe, wherein the ice water generated by the air-conditioning compressor is sent to the chassis through the detachable pipe;
