Detailed Description
The present invention will be described in detail with reference to the following preferred embodiments.
As shown in fig. 1, a hydraulic drive traveling system of a two-section crawler comprises a closed hydraulic system assembly and an operation control system assembly; the closed hydraulic system assembly comprises a pump I1, a pump II 2, a left front motor 3, a rear right motor 4, a front right motor 5 and a rear left motor 6, wherein the pump I1 is diagonally connected with the front left motor 3 and the rear right motor 4 through pipeline joints, and the pump II 2 is diagonally connected with the front right motor 5 and the rear left motor 6 through pipeline joints; and meanwhile, the pressure measuring ports of the first pump 1 and the second pump 2 are communicated through the damping holes by using pipeline joints. The controller 7, the piezoresistor 8, the accelerator pedal 9 and the mode change-over switch 10 form an operation control system assembly; the piezoresistor 8, the accelerator pedal 9 and the mode conversion switch 10 are connected with the controller 7 through a wire harness; the controller 7 is connected with the pump I1, the pump II 2, the left front motor 3, the rear right motor 4, the front right motor 5 and the rear left motor 6 through connectors and wiring harnesses.
The pump I1 is diagonally connected with the front left motor 3 and the rear right motor 4 through the pipeline joints, the pump II 2 is diagonally connected with the front right motor 5 and the rear left motor 6 through the pipeline joints, the pipeline joints can be arranged according to actual structures, and the layout is compact and is not restricted by external structures. The damping hole is used for communicating pressure measuring ports of the first pump 1 and the second pump 2 through pipeline joints so as to make up for individual differences of the pumps. The piezoresistor 8, the accelerator pedal 9 and the mode conversion switch 10 are used for acquiring, inputting and switching signals. The controller 7 may override the pump or motor displacement when the actual engine speed is lower than the set speed to a certain extent; under the similar working conditions of a long downward slope, the engine has the overspeed tendency; when the pressure of the hydraulic system is up to a certain set value, the controller can intervene in time to realize the control functions of flameout prevention, overspeed prevention, electronic anti-slip and the like.
