Front wheel driving control system and method of rubber-tyred paver and rubber-tyred paver

Abstract

The invention relates to an anti-skid front wheel driving control system for a rubber-tyred paver, comprising a first detector, a second detector, a third detector and a control device. The first detector is used for detecting the working travel speed of the rubber-tyred paver; the second detector is used for detecting the steering angle of the rubber-tyred paver; the third detector is used for detecting the load pressure of the rubber-tyred paver; and the controller respectively receives signals from the first detector, the second detector and the third detector, generates and compares a first pre-output value, a second pre-output value and a third pre-output value and outputs the maximum pre-output value as the final output value to a front wheel driving hydraulic circuit of the rubber-tyred paver. Besides, the invention also relates to a rubber-tyred paver provided with the front wheel driving control system of the type and a method of the front wheel driving control system for controlling anti-skid of the rubber-tyred paver.

Description

technical field [0001] The invention relates to a front-wheel drive control system of a tire-type paver, a method for controlling the control system and a tire-type paver with the front-wheel drive control system. 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 oil tank is respectively connected with the constant pressure variable pump, the front wheel driving motor, and the two-way control valve, the constant pressure variable pump is connected with the parallel front wheel driving motor, and one end of the electric proportional control overflow valve passes through the control oil port of the constant pressure variable pump and the constant pressure variable pump. The variable pressure pump is connected with each other, and the other end is connected with the oil tank. Among them, the front wheel au...

Problems solved by technology

However, due to frequent load changes and complex road conditions in actual working conditions, the friction coefficient between the rear wheel of the paver and the ground is quite different, which often causes the rear wheel to slip. Once the rear wheel slips, the signal output by the rear wheel pressure sensor will change. It will become smaller or not, and the front wheel auxiliary drive will be gone, thus losing the role that the front wheel auxiliary drive should play, and the machine's working capacity with load will decrease
