Abstract
The utility model provides an electric automobile actuating system, including driving motor, with the clutch gearbox of driving motor main drive axle connection, driving motor's counter drive axle with turn to oil pump lug connection, driving motor's counter drive axle stretches out and is connected with the inflating pump by turning to the oil pump rear end, installs the pressure valve on the connecting pipeline between inflating pump and gas receiver, the pressure sensor of pressure valve installs in the gas receiver. When the driving motor starts to work, the main drive works, the steering oil pump is directly driven to start to work, the inflating pump is driven to start to work, and when the air pressure in the air storage cylinder is insufficient, the inflating pump starts to work; when the air pressure in the air storage cylinder reaches the pressure, the pressure sensor detects that the air pressure reaches a set value, the pressure valve on the connecting pipeline is closed, and the air storage cylinder is stopped from being inflated; and when the driving motor stops working, the whole system stops working.
Description
Technical field
The utility model relates to a kind of drive system of electric automobile, belongs to braking and hydraulic power-assisted steering technical field in the electronlmobil.
Background technology
Need to use compressed air brake and hydraulic power-assisted steering in the present pure electronic light truck; Thereby need to use electronic inflation pump and electric powered steering oil pump, and these two pumps all need use a motor and inverter to work respectively, not only complex structure, volume is big, cost is high; And because each pump all need be distinguished wiring; Increase the risk of wiring, reduced the reliability that uses, used hidden danger many.
Summary of the invention
The purpose of the utility model is to above-mentioned deficiency; Complex structure, the volume that mainly electronic inflation pump and electric powered steering oil pump exist in the present pure electronic light truck of solution is big, cost is high and use the many shortcomings of hidden danger; A kind of drive system of electric automobile is provided; When adopting a drive motor to realize main the driving, inflation pump, power steerig pump are driven.
The technical scheme of the utility model is achieved in that the drive system of electric automobile of the utility model comprises drive motor; With drive motor main drive shaft bonded assembly clutch transmission; The secondary driving shaft of its drive motor and power steerig pump direct connection; The secondary driving shaft of drive motor is stretched out with inflation pump by the power steerig pump rear end and is connected, setting pressure valve on the connecting line between inflation pump and the air receiver, and the pressure sensor of pressure valve is installed in the air receiver.
The advantage of the utility model: the utility model can not only be realized the repertoire of inflation pump and power steerig pump; And two cover motor and inverters have been saved; Have simple in structure, realize convenient, low, the energy-optimised advantage of cost, and can improve the reliability of service of inflation pump and power steerig pump.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Further specify the utility model below in conjunction with accompanying drawing and embodiment.
The drive system of electric automobile of the utility model comprises drive motor 1; With drive motor 1 main drive shaft 1a bonded assembly clutch transmission 2; It is characterized in that: the secondary driving shaft 1b of drive motor 1 and power steerig pump 3 direct connections; The secondary driving shaft 1b of drive motor 1 is stretched out with inflation pump 4 by power steerig pump 3 rear ends and is connected, setting pressure valve 6 on the connecting line 5 between inflation pump 4 and the air receiver 7, and the pressure sensor 6a of pressure valve 6 is installed in the air receiver 7.
The working process of the utility model is: when drive motor 1 was started working, main driving work directly drove power steerig pump 3 simultaneously and starts working, and drives inflation pump 4 simultaneously and starts working, and when air receiver 7 air pressure inside were not enough, inflation pump 4 was worked always; After air receiver 7 air pressure inside reached pressure, when air receiver 7 internal pressures met the demands, after pressure sensor 6a detected air pressure and reaches pressure, the pressure valve 6 on the connecting line 5 was closed, and stopped inflation in air receiver 7; After drive motor 1 quit work, total system quit work.
The core of the utility model is that inflation pump and power steerig pump have removed motor and the inverter that carries respectively; Power resources are provided for inflation pump and power steerig pump by main drive motor; When main drive motor began to rotate, main drive motor drove power steerig pump work through mechanical system.Drive motor secondary driving shaft 1b drives inflation pump work in the power steerig pump rear end, begins to inflate to air receiver, and inflation pump internal pressure valve cuts out when pressure is enough, stops to inflate to air receiver.Therefore, everyly remove motor and the inverter that inflation pump and power steerig pump carry, power resources are provided for inflation pump and power steerig pump, all belong to the protection domain of the utility model by main drive motor.
