Abstract
A hydraulic driving device for automobile has the main technic content that a power output shaft of a motor rotates a reducer through a clutch, hydraulic oil is absorbed into a one-way hydraulic pump by a closed oil tank through a filter when the reducer rotates the one-way hydraulic pump, hydraulic oil respectively reaches a governor valve and a reversing valve through a pipeline and an accumulator, part of hydraulic oil returns back to the closed oil tank through the governor valve, part of hydraulic oil reaches dual-way hydraulic motor through the reversing valve to drive the dual-way motor rotating, a brake valve is connected with the dual-way hydraulic motor in parallel through an oil pipe, and hydraulic oil is discharged from an output of the dual-way hydraulic motor and then returns back to the closed oil tank through the reversing valve and a cooler. The utility model has the advantages that the driving device takes fewer components, and the utility model is simple in structure, low in cost, safe and reliable in performance, convenient in driving and low in maintenance cost.
Description
Technical field
The utility model relates to automobile, and is particularly relevant with the actuating device on the automobile.
Background technology
The driving device structure complexity of existing automobile, cost of manufacture height, service expenditure height.
Summary of the invention
Main technical schemes of the present utility model is as follows:
The power take-off shaft of driving engine drives reductor by power-transfer clutch and rotates, when reductor drives unidirectional Hydraulic Pump and rotates, hydraulic oil is sucked in the unidirectional Hydraulic Pump through filter by sealed reservoir, hydraulic oil by the road, energy storage, arrive governor valve and change-over valve respectively, part hydraulic oil turns back to sealed reservoir through governor valve, part hydraulic oil arrives two-way hydraulic motor by change-over valve, the driving two-way hydraulic motor rotates, brake valve is by oil pipe and two-way hydraulic motor and connect together, hydraulic oil is exported out by two-way hydraulic motor, through change-over valve, cooling vessel turns back in the sealed reservoir.
Advantage of the present utility model is: the parts that actuating device adopted are less, simple in structure, cost is low, safety performance is reliable, convenient driving, service expenditure are low.
Description of drawings
Concrete structure of the present utility model is provided by the following drawings.
Fig. 1 is the structural representation of this automobile hydraulic drive;
Fig. 2 is the structure cut-away view of the governor valve of this automobile hydraulic drive.
The specific embodiment
Below in conjunction with accompanying drawing specific embodiment of the utility model is described further.
As shown in Figure 1, the power take-off shaft of driving engine 1 drives reductor 3 by power-transfer clutch 2 and rotates, when the unidirectional Hydraulic Pump 5 of reductor 3 drives rotates, hydraulic oil is sucked in the unidirectional Hydraulic Pump 5 through filter 6 by sealed reservoir 7, hydraulic oil by the road, energy storage 4, arrive governor valve 8 and change-over valve 9 respectively, part hydraulic oil turns back to sealed reservoir 7 through governor valve 8, part hydraulic oil arrives two-way hydraulic motor 12 by change-over valve 9, driving two-way hydraulic motor 12 rotates, the rotation of two-way hydraulic motor 12 drives the drive wheel running, makes running car.Hydraulic oil is come out by two-way hydraulic motor 12, gets back in the sealed reservoir 7 through change-over valve 9, cooling vessel 10.
When automobile advanced, with the change-over valve 9 handles P PARK Position P of pushing forward, foot accelerator clutch 2 made driving engine 1 main shaft power pass to unidirectional Hydraulic Pump 5, made unidirectional Hydraulic Pump 5 runnings, again governor valve 8 handles was pushed forward to certain position, and automobile is advanced.
When automobile stops, the handle of governor valve 8 is retracted zero-bit, during the footbrake crank, related brake valve 11 of while, the fuel feed hole of two-way hydraulic motor 12 is linked to each other with oil outlet, at this moment hydraulic oil by two-way hydraulic motor 12, does not directly return sealed reservoir 7, can reduce the damage of the force of inertia of running car to two-way hydraulic motor 12 and other Hydraulic Elements like this.
During reversing automobile, the handle of change-over valve 9 is retracted the reverse position, make the hydraulic oil reverse direction flow, make reversing automobile through two-way hydraulic motor 12.
As shown in Figure 2, the structure cut-away view of governor valve 8, two ends oil inlet 14 and oil outlet 19 are set at valve body about in the of 15, have two oblong valve openings 13, spool 16 up and down in valve body 15 inside, valve core rod 17 is arranged on the spool 16, spool 16 left ends are provided with spring 20, have the oil duct of spattering 18 on the following valve wall of valve body 15.Flow through the oil mass of governor valve 8 by spool 16 control, and the speed of the speed of a motor vehicle can be realized by the flow through oil mass of governor valve 8 of adjusting.
