Abstract
The invention provides an automobile electronic-control hydraulic independent shaft end driving system and belongs to the technical field of automobile driving systems. The automobile electronic-control hydraulic independent shaft end driving system mainly solves the problems of automobile sideslip, large turning land occupation and large braking device abrasion. The automobile electronic-control hydraulic independent shaft end driving system is characterized in that an engine drives a high-pressure oil pump, high-pressure oil in the oil pump is input to the hydraulic oil input end of a wheel shaft end hydraulic motor through four branch oil conveying pipe, each branch oil pipe supplies oil to a three-phase oil tank in three-branch mode, each phase is provided with an electronic-control reversing valve, each branch is provided with a branch flow valve, a master electronic-control flow valve is arranged at the output end of the oil pump, and a computer control chip receives signals from a shaft end sensor and instructions from an operation panel of a cab and an operation mechanism and controls the electronic-control valves through control circuits. The automobile electronic-control hydraulic independent shaft end driving system enables an automobile to perform slipping turning, prevents sideslip effectively, can perform auxiliary braking, and reduces abrasion of a braking device.
Description
Technical field
The invention belongs to the automobile driving system technical field, be specifically related to automobile electrically-controlled fluid power independence axle head drive system.
Background technology
At present, automobile driving system adopts explosive motor through change speed gear box and transfer device power to be reached wheel usually, but traditional transfer device during in turning, through complicated road segment segment, easily produces and breaks away, and in addition, the required space of turning is larger; More can't realize dynamic reverse drive dynamic braking.
Summary of the invention
The objective of the invention is to solve the problem that prior art exists, the automobile electrically-controlled fluid power independence axle head drive system that does not adopt transfer device is provided.
The present invention solves the problems of the technologies described above the technical scheme of taking to be:
Automobile electrically-controlled fluid power independence axle head drive system comprises explosive motor, oil pump, automatically controlled flow valve, automatically controlled direction valve, HM Hydraulic Motor and computer control chip; It is characterized in that: engine output shaft is connected with the oil pump input shaft, and the oil pump high pressure oil is divided into the hydraulic oil input end that four branch road transport pipe input to wheel axle head HM Hydraulic Motor; Each branch road oil pipe divides three road direction three-phase oil cylinder fuel feeding, and each all arranges electric control reversing valve mutually; It is mutually electric control reversing valve of A phase electric control reversing valve, B phase electric control reversing valve and C; Each branch road arranges the branch road flow valve; At the oil pump mouth total automatically controlled flow valve is set, the oil return pipe of each axle head HM Hydraulic Motor by pipe influx in the oil pocket of oil pump;
Described computer control chip receives the signal from the axle head sensor, and each electrically-controlled valve is controlled by control circuit from the guidance panel of operator's compartment and the instruction of operating mechanism.
The present invention compared with prior art has following beneficial effect:
1, because the present invention adopts the axle head HM Hydraulic Motor, make automobile in operational process, can adjust at any time according to condition of road surface rotating speed and the torque of each wheel, effectively prevent from breakking away, and can glide steering, angle of turn is turned little than orthodox car;
2, because the present invention adopts the axle head sensor to the information of computer control chip transmission running state, monitor at any time automobile operating state, adjust engine speed, and the rotating speed of each wheel, auto efficiency is improved;
3, because the present invention adopts independent axle head to drive, when needs brakes, suitable reverse drive was carried out in the control of hydraulic directional control valve that can be by axle head, and the assisting vehicle brake system makes braking more effective, the wearing and tearing of minimizing brake equipment.

Fig. 1 is structural representation of the present invention.
Among the figure: 1-explosive motor; 2-HM Hydraulic Motor; 3-branch road flow valve; 4-oil pump; 5-master control flow valve; 6-A phase electric control reversing valve; 7-B phase electric control reversing valve; 8-C phase electric control reversing valve; 9-oil return pipe.
The specific embodiment
As shown in Figure 1, automobile electrically-controlled fluid power independence axle head drive system comprises explosive motor 1, oil pump 4, automatically controlled flow valve, electric control reversing valve, HM Hydraulic Motor 2 and computer control chip; Be characterized in: explosive motor 1 output shaft is connected with oil pump 4 input shafts, and the oil pump high pressure oil is divided into the hydraulic oil input end that four branch road transport pipe input to respectively wheel axle head HM Hydraulic Motor 2; Each branch road oil pipe divides three road direction three-phase oil cylinder fuel feeding, and each all arranges electric control reversing valve mutually; It is mutually electric control reversing valve 8 of A phase electric control reversing valve 6, B phase electric control reversing valve 7 and C; Each branch road arranges branch road flow valve 3; At the oil pump mouth total automatically controlled flow valve 5 is set, the oil return pipe 9 of each axle head HM Hydraulic Motor 2 by pipe influx in the oil pocket of oil pump;
Described computer control chip receives the signal from the axle head sensor, and each electrically-controlled valve is controlled by control circuit from the guidance panel of operator's compartment and the instruction of operating mechanism.
Working process:
When the present invention uses, by operating mechanism computer chip is sent instruction at operator's compartment, make each axle head HM Hydraulic Motor co-ordination, efficient operation with the best, when occuring to break away, sideslip wheel on one side can stop automatically, and the wheel of another side can automatic increasing torque take away the highway section that generation is breakked away with car; When being traveling in turning road, inboard wheel meeting automatic retarding, the balance of maintenance vehicle; When the needs pivot turn, can select the glide steering pattern; Then can turn around in less space; When automobile need to be braked, but then computer chip sends instruction from electrically-controlled valve of each wheel of trend and changes less reverse actuating force into and carry out dynamic auxiliary braking.
