Abstract
The utility model relates to a water pump of an automobile engine, which can lead the engine to dissipate heat better. The technical scheme includes that the water pump comprises a water pump casing and an impeller. The water pump is characterized in that a direct-current motor is mounted inside the water pump casing, and the impeller is installed on an output shaft of the direct-current motor.
Description
Technical field
The utility model relates to a kind of motor car engine water pump.
Background technique
In the prior art, engine water pump all is the mechanical type water pump, as denomination of invention is " a kind of engine water pump " patent (patent No.: 200820116430.x) disclosed technological scheme, water pump is driven by the motor belt wheel, rotating speed becomes a fixed proportion with engine speed, and change with engine speed change, efficient is low; In cold season, during engine cold-start, thus long engine emission and the passenger comfort of influencing of warm-up period; And automobile is behind anxious stopping at a high speed, and the mechanical type water pump quits work with motor, is unfavorable for engine radiating; Since the water pump Mechanical Driven, axially loaded during work, and working life is short, and the layout of water pump is limited by engine wheel system.
The model utility content
Goal of the invention of the present utility model is to provide a kind of motor car engine water pump, can realize engine radiating better.
Realize the technological scheme of the present utility model purpose:
A kind of motor car engine water pump comprises water pump cover, impeller, it is characterized in that: direct current generator is contained in the water pump cover, on the output shaft of direct current generator impeller is housed.
Water pump cover is provided with overflow hole.
On the output shaft of direct current generator water seal is housed.
The signal input part of direct current generator connects the signal output part of entire car controller ECU, the signal input part sending and receiving motivation cooling-water temperature sensor of entire car controller ECU.
The beneficial effect that the utlity model has:
The utility model engine water pump drives by direct current generator, and after high engine speeds was suddenly stopped, water pump still can work on, and more helps the heat radiation of motor; Entire car controller ECU gathers water temperature signal, exports corresponding control voltage to direct current generator, thereby selects the work operating mode of engine water pump flexibly, improves pump working efficient, shortens warm-up period.Because the utility model is axially no longer stressed when making work by driving with direct current generator, longer service life, simultaneously, the mounting point also no longer is subjected to the accessory wheel system influence, makes easier for installation.

Fig. 2 is a plan view of the present utility model;
Fig. 3 is a worm's eye view of the present utility model;
Fig. 4 is a schematic block circuit diagram of the present utility model.
Embodiment
As Figure 1-3, direct current generator 1 is contained in the water pump cover 3, on the output shaft 2 of direct current generator impeller 6 is housed.Water pump cover is provided with two overflow holes 8, and water seal 5 is housed on the output shaft of direct current generator.
Another more excellent embodiment of the present utility model: the direct current generator in the previous embodiment is controlled by entire car controller ECU, as shown in Figure 4, the signal input part of direct current generator 1 connects the signal output part of entire car controller ECU, the signal input part sending and receiving motivation cooling-water temperature sensor L of entire car controller ECU.Entire car controller ECU controls motor speed by the voltage of control direct current generator 1, thus the rotation of control impeller 6.
When engine cold-start, engine water temperature sensor L passes to entire car controller ECU with signal, and ECU schemes according to motor map, draw the flow that this moment, water pump need produce, control of pump turns round than under the slow-speed of revolution corresponding, make cooling liquid slowly in systemic circulation, thereby shorten warm-up period.
When engine temperature reached and continue in normal working, engine water temperature sensor L passed to entire car controller ECU with signal, and entire car controller ECU is according to motor map figure, and the control of pump corresponding rotating speeds guarantees the cooling system proper functioning.
When motor is at high temperature worked, engine water temperature sensor L passes to entire car controller ECU with signal, and entire car controller ECU draws corresponding flow demand this moment according to motor map figure, water pump is worked under high rotating speed, thereby guarantee the proper functioning of motor.
When automobile in anxious stopping time at a high speed, temperature is still very high in the engine cylinder-body, engine water temperature sensor L passes to entire car controller ECU with signal, entire car controller ECU schemes according to motor map, the control of pump proper functioning still circulates cooling system, guarantees that motor in time cools off.
Claims (4)
