Problems solved by technology

[0002] The speed of the vehicle cannot be accurately controlled when the accelerator pedal of the road-rail dual-purpose tractor is controlled. When driving on the track, if an accurate speed is required to realize the loading of goods on the move, such as filling grain or pulverized coal particles in the compartment, loading After the process goes from carriage to carriage, this requires a steady low speed to accommodate fixed loading equipment
If there are speed fluctuations in the existing throttle control system, it is not conducive to loading the goods in the carriage evenly
At present, the road-rail dual-purpose tractor lacks a constant speed control device

Abstract

The invention relates to a low constant-speed control device for a combined highway and railway tractor, and belongs to a vehicle control system. According to the technical scheme, the low constant-speed control device for the combined highway and railway tractor comprises a control box composed of a controller, a display screen and a speed encoder arranged on a tractor wheel axle; the speed encoder and a displayer are connected to the controller; and control leads of the controller are connected to an engine CPU, a gear selector, a brake and a mode transfer switch respectively. By adding thecontrol device in the original control system, the device can enable a vehicle to run at a constant speed by setting running speed value, which brings convenience to the loading work requiring a certain speed. The device has low adding cost and is suitable for being directly added to the existing control system for use. The device has the advantages of simple control mode, high integration degreeand convenience in control.

Description

technical field [0001] The invention relates to a low constant speed control device for a road-rail dual-purpose tractor, which belongs to a vehicle control system. Background technique [0002] The speed of the vehicle cannot be accurately controlled when the accelerator pedal of the road-rail dual-purpose tractor is controlled. When driving on the track, if an accurate speed is required to realize the loading of goods on the move, such as filling grain or pulverized coal particles in the compartment, loading After the process goes from carriage to carriage, this requires a steady low-speed drive to accommodate stationary loading equipment. If the existing throttle control system fluctuates in speed, it is unfavorable for the goods to be loaded evenly in the compartment. And at present road-rail dual-purpose tractor lacks constant speed control device. Contents of the invention [0003] The invention provides a low-constant-speed control device for a dual-purpose road-r...
