Abstract

The invention discloses an emergency drive system for a super-large electric transmission wheel loader, which comprises a power system, a walking system, a steering system, an emergency steering system and a vehicle control system, and can quickly start the emergency drive when the vehicle fails, Drive the vehicle to the designated location. The emergency treatment strategy is added, and a control method for the emergency drive system of a super-large electric drive wheel loader is also disclosed. According to different fault types of the vehicle, different emergency drive controls are performed according to different types of faults, so as to improve the vehicle's driving stability and safety.

Description

technical field [0001] The invention relates to an emergency drive system for a super-large electric transmission wheel loader, and also relates to a control method for the emergency drive system, which belongs to the technical field of new energy hybrid power. Background technique [0002] In order to meet the requirements of continuous improvement of construction operation efficiency, loaders are gradually developing towards large-scale. These super-large-tonnage loaders have large volume, high quality, and large power matching requirements. The core structure and transmission components such as gearboxes and drive axles are selected. Type matching is difficult, and the price is high. At the same time, the increasing demand for transmission torque makes the design and manufacture of hydraulic systems more and more difficult. Therefore, the electric transmission scheme is the mainstream technical route for the research and development of ultra-large loaders at present. [...
