Embodiment Construction

[0051] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0052] Combine below figure 1 with figure 2 A rear-wheel-drive electric wheel work vehicle will be described as an example.

[0053] The electric wheel work vehicle 100 includes a body 1 , front wheels 2 and rear wheels 3 . The front wheels 2 are arranged on the front portion of the vehicle body 1 as steering wheels providing steering functions. The rear wheels 3 are arranged at the rear of the vehicle body 1 as driving wheels providing driving and braking functions.

[0054] The engine 11 is arranged inside the vehicle body 1, and a large diesel engine can be used. The engine 11 drives the generator 12 to generate three-phase alternating current (for example, about 1500KW). The traction converter 13 and the vehicle controller 15 jointly complete the speed con...

Abstract

The invention provides a system and a method for controlling the running speed of an electric wheel operation vehicle. The system comprises a speed setting module, a whole vehicle controller and a traction converter, wherein the speed setting module is used for setting the target speed and the minimum speed threshold value, the whole vehicle controller is connected with a speed sensor arranged at a vehicle body for collecting the practical running speed of the vehicle and is connected with an angle sensor for judging the gradient of the vehicle running road segment, the traction converter is connected with the whole vehicle controller, and is used for converting alternating current output by a generator into driving force to be provided for an electric motor working in a traction mode, or converting the alternating current into braking force to be provided for the electric motor working in a braking mode, and the whole vehicle controller controls the value of the driving force moment or the braking force moment provided for the electric motor in a constant speed control mode according to the practical running speed of the vehicle and the gradient of the vehicle running road segment, so that the vehicle running speed is within the range of the target speed and the minimum speed threshold value.

Description

technical field [0001] The invention relates to the technical field of electric wheel work vehicles, in particular to a system and method for controlling the driving speed of electric wheel work vehicles. Background technique [0002] In recent years, with the increasing mining and construction of large-scale open-pit mines, the demand for heavy-duty mining vehicles as the main mine transportation tool has grown rapidly. Among them, the electric wheel operation vehicle belongs to one of the most important types of mining vehicles. Due to the gradual development of large-scale electric wheel operation vehicles, the load capacity continues to increase, and their operating environments are mostly complex roads with many slopes such as mines, which put forward higher requirements for vehicle driving safety. [0003] For example, electric wheel dump trucks are used to transport sand and gravel, coal and ore, etc., and drive in open-air non-highway areas. The road conditions are ...
