Abstract
An automobile electric steering pump is disclosed, which belongs to the electric steering oil pump field. An oil pump motor, an oil pump, an oil tank, a packed bed filter and a motor controller and so on are integrated into one machine. The oil pump and the packed bed filter are immersed in the oil tank, a return oil connector is fixed on the top cover of the oil tank. The packed bed filter is connected to the lower end of the return oil connector in the oil tank; the oil pump is connected with a drive motor through a connection end cap; a motor controller is directly fixed on the motor of the oil tank and the oil pump. Flow dividers are cancelled and connections and installations and are simplified. The oil pump is driven by a permanently magnetic brushless motor. Under the function of the controller, motor speed keeps constant and will not vary with load of the oil pump to ensure constant output of the oil pump. Accordingly, the utility model is advantageous in high efficiency, compactness, light weight, being free of carbon brush, long life and simple maintenance and so on.
Description
Technical field
The utility model belongs to electric powered steering oil pump field, is specifically related to a kind of motorcar electric steering pump of battery-driven car electric powered steering control.
Technical background
Traditional ICE-powered vehicle of using, its steering hydraulic oil pump are by internal combustion engine drive, because the hydraulic oil pump rotating speed changes with internal-combustion engine rotational speed.In order to guarantee combustion engine under idling operation, vehicle also can turn to; The discharge capacity of oil pump, determine by the idling for internal combustion engine rotating speed, in order to prevent when combustion engine is higher than idling speed work, the oil pump delivery rate is excessive, need single channel flow stabilizing valve (or permanent flow valve), this not only makes complex structure, and because when combustion engine was higher than idling speed work, the unnecessary flow of oil pump output caused loss in efficiency through single channel flow stabilizing valve (or permanent flow valve) bypass oil sump tank.
Summary of the invention
The purpose of this utility model provides has electronically controlled a kind of motorcar electric steering pump.It is characterized in that, oil pump 1 and fil 2 are immersed in the petrol storage tank 3, and back leakage connection 5 is fixed on the top cover 4 of petrol storage tank 3, and fil 2 is connected back leakage connection 5 lower ends in petrol storage tank 3, oil inlet 9 is on back leakage connection 5, and oil outlet 10 is on the end face of connection end cap 8 one sides of oil pump 1; Oil pump 1 is connected with drive motor 7 by connecting end cap 8; Electric machine controller 6 directly is fixed on petrol storage tank 3 and the oil pump drive motor 7.
Described oil pump drive motor is the brushless, permanently excited direct current motor with speed closed loop.
The beneficial effects of the utility model are: 1) petrol storage tank, oil pump, drive motor and controller are integrated into an integral body, and compact conformation, pipeline are connected with circuit simply, and outside needs two oil pipes to be connected with steering booster, and two power leads are connected with power supply; 2) oil pump is immersed in the hydraulic oil, no chargine line, and hydraulic oil can directly enter the pump oil inlet, and the oil suction resistance is little; 3) adopt brushless, permanently excited direct current motor, under the control of controller, it is constant that motor speed can keep, and motor speed does not change with the variation of oil pump load, guarantees oil pump constant current output, so need not add flow divider valve, loss in efficiency is little; Efficient height, volume are little, in light weight, non-carbonate, the life-span long, it is simple to safeguard, are fit to the application of elec. vehicle better.
Description of drawings
Fig. 1 is an electric powered steering oil pump structure scheme drawing.
The specific embodiment
The utility model provides has electronically controlled a kind of motorcar electric steering pump.In electric powered steering oil pump structure scheme drawing shown in Figure 1, oil pump 1 links together by connecting end cap 8 (double as motor front end cover) and motor 7, form an integral body, on the side of connection end cap 8 oil outlet is arranged, be communicated with oil outlet on the oil pump end face by the oil duct that connects on the end cap 8, the oil outlet on this side is connected with the power steering device; Connect the also butt flange of double as motor front end cover and Oil pump electrical machinery assembly and petrol storage tank of end cap 8; Oil pump 1 is built in the petrol storage tank 3, has therefore saved chargine line; Be fixed with back leakage connection 5 on the top cover 4 of petrol storage tank 3, the port of back leakage connection 5 is the oil inlet 9 of oil return; The oil return line of power steering device back leakage connection therewith connects, and is connected with fil 2 in back leakage connection 5 lower ends, and fil 2 places in the petrol storage tank 3 simultaneously.Electric machine controller 6 directly is fixed on the motor 7.
Oil pump electrical machinery of the present utility model, oil pump, oil storage tank, cleaner, electric machine controller etc. integrate. Oil pump is immersed in the hydraulic oil. This oil pump is designed to oil-in in pump one side, pumps hydraulic fluid port at the pump end face. Oil Pump adopts the permanent magnetism brushless direct current motor with speed closed loop to drive, and directly motor and oil pump is designed to One, under the driving of motor, fluid flows to the connection end cap through pump then from oil pump one effluent oil-feed pump, and Flow out from the oil-out that connects on the end cap side, simplified connection and installation. The driving of oil pump adopts permanent magnetism brushless Dc motor, have thus that efficient height, volume are little, in light weight, non-carbonate, the life-span long, safeguard simple etc. Advantage.
