Disengaging shaft type double-power hybrid engineering van

Abstract

The invention discloses a disengaging shaft type double-power hybrid engineering van. The disengaging shaft type double-power hybrid engineering van comprises a front wheel electric drive system providing power for front wheels through electric driving, a rear wheel mechanical drive system providing power for rear wheels through mechanical driving, and a whole vehicle controller electrically connected with the front wheel electric drive system and the rear wheel mechanical drive system; when the speed of the engineering van is smaller than a set threshold value, the whole vehicle controller controls the front wheel electric drive system to provide power for the front wheels, and the rear wheel mechanical drive system provides power for the rear wheels; when the speed of the engineering van is not smaller than the set threshold value, the front wheel electric drive system does not provide power for the front wheel, and the rear wheel mechanical drive system provides power for the rear wheels. The problem that the vehicle travels hard under the conditions of loaded starting and climbing is solved, and environment pollution caused by insufficient burning of fuel of the rear wheel mechanical drive system is avoided.

Description

technical field [0001] The invention relates to the technical field of engineering vehicles. More specifically, the present invention relates to a split-axle dual-power hybrid engineering vehicle. Background technique [0002] The power system of traditional engineering vehicles is mostly driven by rear wheel machinery. Engineering vehicles are often used in special short-distance cycle transportation, and the working conditions are harsh, especially when the vehicle starts with a heavy load, climbs a slope with a heavy load, or travels on slippery roads. At this time, due to insufficient power or insufficient adhesion, the vehicle is difficult to drive normally, and the driver has to shift down or step on the accelerator; at the same time, when the vehicle has sufficient power but cannot drive normally, the fuel efficiency of the engine is very low, which will cause pollution to the environment . [0003] In recent years, electric vehicle technology has been increasingly ...

Problems solved by technology

[0006] Still another object of the present invention is to provide a split-axle dual-power hybrid construction vehicle, which is provided with a front-wheel electric drive system that provides power for the two front wheels at the front of the construction vehicle, and a front-wheel electric drive system that provides power for the two rear wheels at the rear. The rear wheel mechanical transmission system of the power realizes dual power drive. At the same time, a vehicle controller is set up, which can output commands to the front wheel electric drive system according to the speed of the engineering vehicle. When the engineering vehicle is at a low speed, the vehicle controller controls the front wheel. The wheel-electric drive system provides power to the two front wheels of the engineering vehicle, and on the contrary, it does not provide power, thus overcoming the difficulty of driving the vehicle under heavy vehicle starting, climbing and other working conditions, and avoiding the rear wheel mechanical transmission system due to fuel Environmental Pollution Caused by Insufficient Combustion
