Distributive electric-drive hinge steering tracked vehicle

Abstract

The invention discloses a distributive electric-drive hinge steering tracked vehicle, and belongs to the technical field of transmission of tracked vehicles. A hybrid power distributive electric drive system is applied to a tracked vehicle; and the system consists of an engine, a gearbox, a generator, an electric energy management module, a whole vehicle controller, a power battery set, a motor controller, four drive motors and a transmission. The engine, the gearbox and the generator are connected to form a power generation system for providing electric energy to an electric energy management system; the electric energy management module is connected with the power battery set and the motor controller for controlling the power battery set to charge and generate electricity and to provide the electric energy to the motor controller; the motor controller independently controls four drive motors; the four drive motors are connected with driving wheels through a reduction gearbox or the transmission; and the four driving wheels drive four tracks to rotate. The distributive electric-drive hinge steering tracked vehicle simplifies a transmission system, is flexible in power distribution, and improves the cross-country maneuvering and fuel economic performance.

Description

technical field [0001] The invention relates to the technical field of crawler vehicle transmission, in particular to a hybrid drive system for a double-jointed articulated steering tracked vehicle. Background technique [0002] The double-joint articulated steering crawler vehicle has two car bodies, a front body 11 and a rear body 13, which are connected by an articulated steering device 12, as attached figure 2 As shown, the articulated steering device 12 can control the relative rotation and pitch of the front and rear two car bodies, and has strong passing performance and maneuverability. Widely used in high-speed transport vehicles in complex terrain such as mountains, snow, swamps, river beaches, and deserts. With the improvement of vehicle maneuverability, handling stability and fuel economy requirements, it is more urgent to adopt new high-efficiency drive technology. Distributed electric drive technology has the advantages of flexible layout and space saving, sho...

AI Technical Summary

Problems solved by technology

However, the current hydraulic distributed drive technology is not mature enough in terms of control.

Hydraulic transmission not only has low driving efficiency and slow control response, but also requires complex auxiliary systems, such as liquid replenishment tanks, oil filters, hydraulic oil cooling systems, etc., which also require high maintenance

The hydraulic drive has only a single power source, which cannot achieve super-power operation, and has limited passing ability and rapid acceleration ability on extremely difficult roads.
