Front-wheel drive control system for tire-type paver anti-skid

Abstract

The invention provides an anti-slipping front wheel driving control system for a tire type paver. The anti-slipping front wheel driving control system is characterized by mainly comprising a controller and a rear wheel speed sensor, wherein the controller is used for detecting a signal output by a knob / pedal and the rear wheel walking speed, carrying out selective processing on an input signal according to an instruction of a functional switch, outputting a working state instruction for controlling a front wheel walking pump and a rear wheel walking pump, and controlling the displacements of the front wheel walking pump and the rear wheel walking pump; the rear wheel speed sensor is used for feeding the rear wheel walking speed back to the controller; and the speed of a front wheel is controlled to be higher than that of a rear wheel under the condition that the front wheel drives the paver in an auxiliary manner. The anti-slipping front wheel driving control system has the advantage of being designed aiming at an actual condition when the paver slips; the rear wheel is controlled by a closed ring and the driving speed is stabilized; the speed of the front wheel is slightly 3-5% higher than that of the rear wheel, so as to realize an auxiliary driving effect; the anti-slipping front wheel driving control system is simple and reliable and low in cost, and saves power; and the matched driving is carried out by the front wheel according to the speed of the rear wheel, the simple control can well realize the condition of auxiliary driving by the front wheel and the rear wheel can be effectively prevented from being slipped.

Description

technical field [0001] The present invention relates to a front-wheel drive control system of a tire-type paver, in particular to a front-wheel drive control system for anti-skid of the tire-type paver. Background technique [0002] In the prior art, the front wheel drive hydraulic circuit of the tire paver includes a fuel tank, a constant pressure variable pump, a front wheel travel motor, and a two-way control valve. The fuel tank is respectively connected to the constant pressure variable pump, the front wheel driving motor, and the Unicom control valve. The constant pressure variable pump is connected to the parallel front wheel driving motor. The variable pump is connected, and the other end is connected with the oil tank. Among them, the front wheel auxiliary drive of the tire paver controls the electric proportional overflow valve through the pressure sensors assembled on the left and right rear wheels, thereby changing the output pressure of the constant pressure va...
