Abstract
The invention relates to a water temperature adjusting device for an automobile motor, which comprises a thermo-regulator base, a driving shaft, a disk valve, a stepping motor, a water temperature sensor and an electronic control unit ECU of the motor. The inner portion of the thermo-regulator base is provided with a lesser circulation pore passage and a major circulation pore passage for cooling water. The driving shaft, the disk valve and the water temperature sensor are installed in the inner portion of the thermo-regulator base, the driving shaft and the disk valve are an integral structure of two coaxial valves, namely that two valve blocks which are staggered and mutually perpendicular are fixed on the driving shaft, and the two valve blocks are respectively arranged on the lesser circulation pore passage and the major circulation pore passage of the thermo-regulator base, and the driving shaft is connected with the stepping motor. The water temperature sensor and the step motor are respectively connected with the electronic control unit ECU of the motor through a signal line and a control line. The device can control cooling temperature of the motor more accurately and close the lesser circulation of cooling water when the heat load of the motor is much higher, increases the cooling effect of circulation water of the motor, and reduces the power loss of the motor.
Description
Technical field
The invention belongs to the automobile engine water temperature regulation technology, be specifically related to control engine water temperature.
Background technique
At present, water temperature regulation device is to utilize be heated situation generation solid and liquid of paraffin to transform mutually on the common engine, increases or reduces volume and open or close cylinder head cooling water and regulate engine water temperature to the passage that radiator flows.This water temperature method of controlling is the cooling water temperature of application cylider cover outlet accurately; The engine cooling water short circle is often opened, and cooling water can not all cool off by radiator when the motor high heat load, and the mechanical water pump load is bigger, and engine power loss is big; The cooling water channel flow resistance is big.
Summary of the invention
The objective of the invention is deficiency, propose a kind of engine water temperature regulation device, to control engine coolant temperature more accurately at the prior art existence.
This engine water temperature regulation device is made up of thermolator base, live axle and disc valve, stepper motor, cooling-water temperature sensor and engine electronic control unit ECU.Cooling water short circle and major cycle duct are arranged in the thermolator base, cooling water intake through cylinder cap is arranged on the thermolator base, connect the major cycle water out of radiator and the short circle water out of water pump.Live axle and disc valve and cooling-water temperature sensor are installed in the thermolator base the inside, live axle and disc valve are coaxial double-valve structure integrative-structures, promptly being fixed with two positions on live axle staggers and orthogonal valve block, this two valve block lays respectively on the short circle duct and major cycle duct of thermolator base, and live axle is connected with stepper motor.Cooling-water temperature sensor links to each other with engine electronic control unit ECU with guide line by signaling line respectively with stepper motor.
Control flows is to the short circle water hole of water pump with flow to the switching in the major cycle water hole of radiator respectively by disc valve for this device, and when guaranteeing the short circle standard-sized sheet, the cooling water that flows to thermolator base through cylinder cap is inflow radiator not; When short circle was closed, cooling water all flow through radiator.Live axle and disc valve are by step motor drive, and the electric energy of stepper motor and control signal are provided by engine electronic control unit (ECU).Cooling-water temperature sensor links to each other with engine electronic control unit (ECU), and (ECU) provides water temperature signal to engine electronic control unit.Engine electronic control unit (ECU) is regulated live axle and disc valve aperture to regulate water temperature according to water temperature height drive stepping motor.
The present invention is having the following advantages:
1. can control engine coolant temperature more accurately.
2. can close cooling water short circle (cooling water directly enters crankcase, cylinder cap water jacket without radiator) at engine heat load when higher, improve engine cycles water cooling effect, reduce engine power loss.
3. can reduce the cooling water channel flow resistance.
4. improve reliability and the auditability that engine temperature is regulated.

Embodiment
Referring to Fig. 2 and Fig. 1, this thermoregulator device is made up of thermolator base 5, live axle and disc valve 4, stepper motor 3, water temperature sensor 1 and engine electronic control unit (ECU) 2.The short circle water out C that cooling water intake A through cylinder cap, the major cycle water out B that connects radiator and water pump are arranged on the thermolator base 5.Live axle and disc valve 4 and cooling-water temperature sensor 1 are installed in thermolator base 5 the insides, live axle and disc valve 4 are integrative-structures of a coaxial bivalve, promptly being fixed with two positions on live axle 41 staggers and orthogonal big or small valve block 42,43, big valve block 42 is arranged in the major cycle duct of thermolator base, and little valve block 43 is arranged in the short circle duct of thermolator base.Live axle 41 is connected with stepper motor 3, cooling-water temperature sensor 1 links to each other with engine electronic control unit ECU2 with guide line by signaling line respectively with stepper motor 3, the electric energy of stepper motor 3 and control signal are provided by engine electronic control unit (ECU) 2, and cooling-water temperature sensor 1 provides water temperature signal to engine electronic control unit (ECU) 2.
During work, by engine electronic control unit (ECU) 2 according to water temperature height drive stepping motor 3, stepper motor 3 is regulated live axle 41, big or small disc valve 42 and 43 on it rotates thereupon, as shown in Figure 1, the aperture of size disc valve 42 and 43 in size circulation duct changes, and can regulate the water yield that flow to radiator and flow back to water pump, regulates engine water temperature.As shown in Figure 3, when big disc valve 42 went to Close All major cycle duct, 43 of little disc valves were in full-gear, and major cycle is closed like this, and cooling water directly flows back to water pump, not inflow radiator through the cooling water that cylinder cap flows to thermolator base.As shown in Figure 4, when little disc valve 43 went to Close All short circle duct, big disc valve 42 was in full-gear again, and short circle is closed like this, and cooling water all flows through radiator.
