Description
Technical field
The utility model belongs to the start and stop technical field of motor, is specifically related to a kind of engine hydraulic start stop system.
Background technique
Traditional motor and oil hydraulic pump assembly comprise motor, oil hydraulic pump, and driver can manually boot motor or kill engine, but motor can not open and close automatically.Have document to propose a kind of motor start stop system, as shown in Figure 1, in traditional motor and oil hydraulic pump assembly, increase following element: starting motor 2, accumulator 5 and solenoid valve group 6, working procedure is:
When engine work, the solenoid valve group 6 be connected with hydraulic pump outlet connects oil hydraulic pump and accumulator, to accumulator pressurizing; When motor is in idling and car load is in wait state, kill engine; When car load restarts work and needs engine start, solenoid valve group turn-on accumulator and starting motor, drive motor ato unit.
Above-mentioned motor start and stop scheme is adopted to have following shortcoming:
Need to increase starting motor, cause the cost of system to increase; This motor also at consumed energy, it reduces the energy-saving effect of system when engine work.
Model utility content
For the shortcoming of traditional scheme, this programme proposes a kind of brand-new engine hydraulic start stop system, and this programme is as follows: a kind of engine hydraulic start stop system, comprises motor, oil hydraulic pump two, oil hydraulic pump three, oil hydraulic pump four, hydrovalve; Motor is connected with three hydraulic pump drivings respectively, and wherein, oil hydraulic pump three can export high pressure oil to hydrovalve under the driving of motor;
Also comprise one-way valve, solenoid valve one, solenoid valve two, reduction valve, accumulator; Described one-way valve is arranged on the inlet port of oil hydraulic pump three, and is communicated with fuel tank; Hydrovalve is communicated with solenoid valve one, to solenoid valve one fuel feeding; Solenoid valve one is connected with accumulator, when the electromagnet of solenoid valve one obtains electric, to accumulator fuel feeding; Solenoid valve two connects accumulator and one-way valve, and when the electromagnet of solenoid valve two obtains electric, the high pressure oil in accumulator enters one-way valve and oil hydraulic pump three by solenoid valve two, now, oil hydraulic pump three is in motor operating conditions, under the driving of the high pressure oil that oil hydraulic pump three exports at accumulator, and ato unit;
Reduction valve is connected with the control port of oil hydraulic pump three, and when an engine is stopped, oil hydraulic pump four does not rotate, and does not have hydraulic oil to output to the control port of oil hydraulic pump three; High pressure oil now in accumulator can enter the control port of oil hydraulic pump three by solenoid valve two and reduction valve, control the discharge capacity of oil hydraulic pump three.
Further, described oil hydraulic pump three is pump motor when restarting motor.
Utility model works process is as follows:
When engine work, the solenoid valve group be connected with hydraulic pump outlet connects oil hydraulic pump and accumulator, to accumulator pressurizing.
When motor is in idling and car load is in wait state, kill engine.
When car load restarts work and needs engine start, solenoid valve group turn-on accumulator and pump motor, pump motor starting motor.Now pump motor is by one-way valve oil suction from fuel tank, and output torque is to motor, and ato unit is to rated speed.
The utility model is compared original technological scheme and is reduced cost, decreases energy ezpenditure, reaches the effect of energy saving of system.
Accompanying drawing explanation
Fig. 1 is original motor start stop system structure principle chart;
Fig. 2 is the utility model engine hydraulic start stop system structure principle chart.
Drawing reference numeral illustrates: 1, motor, 2, oil hydraulic pump two, 3, oil hydraulic pump three, 4, oil hydraulic pump four, 5, hydrovalve, 6, one-way valve, 7, solenoid valve one, 8, solenoid valve two, 9, reduction valve, 10, accumulator, 11, fuel tank.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, and as shown in Figure 2: motor 1, oil hydraulic pump 22, oil hydraulic pump 33, oil hydraulic pump 44, hydrovalve 5 is all former truck system.Wherein, oil hydraulic pump 33 is pump motors, and when normally working, oil hydraulic pump 33 is in pump condition, under the driving of motor 1, export high pressure oil to hydrovalve 5.
One-way valve 6 is arranged on the inlet port of oil hydraulic pump 33, and is communicated with fuel tank 11.Hydrovalve 5 is communicated with solenoid valve 1, to solenoid valve 1 fuel feeding.Solenoid valve 1 is connected with accumulator 10, when the electromagnet of solenoid valve 1 obtains electric, to accumulator 10 fuel feeding.Solenoid valve 28 connects accumulator 10 and one-way valve 6, when the electromagnet of solenoid valve 28 obtains electric, high pressure oil in accumulator enters one-way valve 6 and oil hydraulic pump 33 by solenoid valve 28, now, oil hydraulic pump 33 is in motor operating conditions, under the driving of the high pressure oil that oil hydraulic pump 33 exports at accumulator 10, ato unit.Reduction valve 9 is connected with the control port of oil hydraulic pump 33, when an engine is stopped, oil hydraulic pump 44 does not rotate, hydraulic oil is not had to output to the control port of oil hydraulic pump 33, now, need the high pressure oil in accumulator 10 to enter the control port of oil hydraulic pump 33 by solenoid valve 8 and reduction valve 9, the discharge capacity of oil hydraulic pump 33 is controlled.
Specific works process is: when engine work, and the solenoid valve group 6 be connected with hydraulic pump outlet connects oil hydraulic pump and accumulator, to accumulator pressurizing.
When motor is in idling and car load is in wait state, kill engine.
When car load restarts work and needs engine start, solenoid valve group turn-on accumulator and pump motor, pump motor starting motor.Now pump motor is by one-way valve oil suction from fuel tank, and output torque is to motor, and ato unit is to rated speed.
Above to the utility model more preferably embodiment be described in detail, for one of ordinary skill in the art, according to the thought of the utility model embodiment, all will change in specific embodiments and applications, all can do respective change according to actual demand.In sum, this description should not be construed as the restriction to model utility.
