Abstract

The invention belongs to the technical field of hybrid power control systems, and particularly relates to a hybrid power mining dump truck driving system which comprises an engine, a generator, an electric driving system, a storage battery, a hub driving system 1 and a hub driving system 2. The engine is connected with the generator; the generator and the storage battery are connected with the electric driving system; the electric driving system is connected with the hub driving system 1 and the hub driving system 2. During traction, the storage battery supplies energy to the driving system, when the electric quantity of the storage battery is lower than a set lowest threshold value, the engine drives the generator to rotate to supply energy to the electric driving system, and the electricdriving system outputs energy to drive the hub driving system 1, the hub driving system 2 and a traction dumper to operate. During braking, the hub driving system 1 and the hub driving system 2 inputenergy to the electric driving system, the electric driving system charges the storage battery, and the purpose of saving energy is achieved.

Description

technical field [0001] The invention belongs to the technical field of hybrid power control systems, and in particular relates to a driving system of a hybrid power mining dump truck. Background technique [0002] With the development of motor and control technology, electric transmission mining vehicles have an absolute advantage in large-scale mine earthwork transportation. The electric transmission mine car system is simple, easy to maintain and the engine runs efficiently, so the mine electric vehicle can minimize the energy consumption of the vehicle and improve the transportation efficiency. At present, the mining electric drive dump trucks in operation mainly use the engine to provide energy during traction, and the feedback energy during braking is consumed through the braking resistor grid, and the braking feedback energy has not been fully utilized, which also increases fuel consumption. Cause waste and increase vehicle operating costs. [0003] The working cycle...
