Embodiment Construction
[0015] see figure 2 with figure 1 , The thermostat device consists of a thermostat seat 5, a drive shaft and a disc valve 4, a stepper motor 3, a water temperature sensor 1 and an engine electronic control unit (ECU) 2. The cooling water inlet A through the cylinder head, the large circulating water outlet B connected to the radiator and the small circulating water outlet C connected to the water pump are arranged on the thermostat seat 5 . The drive shaft, the disc valve 4 and the water temperature sensor 1 are installed inside the thermostat seat 5. The drive shaft and the disc valve 4 are an integrated structure of coaxial double valves, that is, two positions are fixed on the drive shaft 41 and The large and small valve plates 42 and 43 perpendicular to each other, the large valve plate 42 is located in the large circulation channel of the thermostat seat, and the small valve plate 43 is located in the small circulation channel of the thermostat seat. The drive shaft 41...

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 stepping motor are respectively connected with the electronic control unit ECU of the motor through a signal line and a control line. The invention can more accurately control cooling temperature of the motor, can 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 [0001] The invention belongs to the automobile engine water temperature regulation technology, in particular to the control of the engine water temperature. Background technique [0002] At present, the water temperature regulating device on the common engine is to use the heating of the paraffin to convert solid and liquid into each other, increase or decrease the volume and open or close the channel for the cylinder head cooling water to flow to the radiator to adjust the engine water temperature. This water temperature control method cannot accurately control the cooling water temperature at the outlet of the cylinder head; the small engine cooling water cycle is always open, and the cooling water cannot be completely cooled by the radiator when the engine is under high heat load, the mechanical load of the water pump is large, and the engine power loss is large; The flow resistance of the cooling channel is large. Contents of the invention [0003] The...
