Description
Technical field
What this utility model related to car engine cooling system starts Water pump clutch, specifically a kind of anti-inefficacy speed governing Electromagnetic water pump clutch.
Background technology
In clutch bell housing between electromotor and change speed gear box, being fixed on the back plane of flywheel with screw by clutch assembly, the output shaft of clutch is exactly the power shaft of change speed gear box. In vehicle traveling process, driver can tip into or out clutch pedal as required, makes electromotor be temporarily separated with change speed gear box and engage gradually, with the power cut off or transmission electromotor inputs to variator. Clutch is the common components in machine driving, drive system can be separated at any time or engage. Clutch has smooth engagement, separates rapidly and thoroughly; It is convenient to regulate and repair; Contour dimension is little; Quality is little; Wearability is good and has the features such as enough heat-sinking capabilities.
Up to now, it is widely used in the explosive motor used by mechanical engineering such as automobile, tractor, boats and ships, generating set, engineering machinery and is equipped with cooling system, these cooling systems are equipped with the water pump for carrying Cooling Water, but, these water pumps are all adopt the structure that mechanical type drives, gear ratio is fixing at present. So no matter how electromotor internal loading changes, water temperature is high or low, discharge be good or bad, water pump pump water, pump how much water etc. need to do not needed, the work of water pump is all by a kind of fixing connected mode and fixing gear ratio pump water, say, that it is all with same gear ratio, same rotary speed working.
Research shows that electromotor engine efficiency when 83 DEG C-93 DEG C is the highest. The prior art engine start warming up time is about 20-30 minute, adopts the technology of the present invention to improve about about 10 minutes rear engine warming up time. In automobile normal running process, the time of 60% is not need water pump high-speed cruising, Fast Cooling is needed under climbing or heavy duty situation, but, for electromotor, its internal water temperature is equivalent to the body temperature of people, only the body temperature of people is normal, and the health of people can be healthy. The body temperature of people is once change, and health arises that problem, is also same reason for the engine, and therefore, the temperature maintaining electromotor is even more important. The water pump of apparent said structure design, also cannot adapt to the protean work process requirement of electromotor, even many times also can cause undue cooling, reduces engine efficiency, works the mischief to electromotor, and substantial amounts of wastes energy. The only comparatively short time, is the job requirement just meeting electromotor. For above-mentioned this to pump and the inharmonic duty of electromotor, it be badly in need of those skilled in the art and make improvement.
Utility model content
Utility model purpose: the purpose of this utility model is to solve the deficiencies in the prior art, a kind of anti-inefficacy speed governing electric control pump is provided, this electric control pump can adapt in the protean work process requirement of electromotor, rotating speed suitable in electromotor runs, such that it is able to reach effect energy-efficient, safe operation.
Technical scheme: in order to realize object above, the anti-inefficacy speed governing electric control pump of one described in the utility model, it includes: belt pulley, upper cover, bearing, water seal, main shaft and water pump cover, one end of described main shaft is connected with water pump cover, the other end of main shaft extends in upper cover, upper cover is connected with belt pulley, belt pulley is connected with water pump cover by bearing, main shaft be radially provided with water seal and water pump cover, it also includes: driving disc spacing pressing, frictional disk, fixing seat, belt pulley magnechuck and solenoid, described driving disc spacing pressing and frictional disk are compressed by spring leaf, frictional disk is sheathed on described fixing seat, fixed seating is located on main shaft, belt pulley magnechuck is positioned at the left side of driving disc spacing pressing, it is provided with clutch solenoid described in solenoid in belt pulley to be connected with ECU.
As of the present utility model it is preferred that, described frictional disk adopts together with pre-pressing technology with driving disc spacing pressing.
As of the present utility model it is preferred that, described rivet sequentially passes through spring leaf, gap pad one and driving disc spacing pressing and is integrally forming parts together with securing it within. In assembling process, driving disc spacing pressing and belt pulley magnechuck gap are 1.5mm. When press-fiting frictional disk, by the rivet on driving disc spacing pressing to the direction pretension 1mm of spring leaf, the gap of driving disc spacing pressing now and belt pulley magnechuck becomes 0.5mm, compressed by Spring deformation 1mm between frictional disk and driving disc spacing pressing assembly, thrust ensure water pump water pump when non-electromagnetic-force be in high speed rotating, reach to prevent frictional disk from coming off from driving disc spacing pressing and make thrust lose efficacy situation generation.
As of the present utility model it is preferred that, the adhesive identity distance of the driving disc spacing pressing after compression and belt pulley magnechuck is from for 0.3mm-0.5mm.
As of the present utility model it is preferred that, be provided with permanent magnet and magnet ring in described upper cover.
As of the present utility model it is preferred that, the gap of described permanent magnet and frictional disk is about 1mm.
As of the present utility model it is preferred that, in described water pump cover, water pump vane is installed.
As of the present utility model it is preferred that, the thickness of spring leaf is 1.2mm, and material is 65Mn, 65Mn after thermally treated and Cold-draw Hardening, and intensity is higher, has certain toughness and plasticity; Under similar face state and complete through hardening situation, fatigue limit is suitable with alloy spring, is effectively ensured spring leaf reliability operationally.
Operation principle: when electromotor just starts, owing to water temperature is relatively low, ECU provides clutch solenoid power on signal, and frictional disk separates with driving disc spacing pressing, and water pump makes low cruise, electromotor rapid warming-up to catch up with lid. When engine water temperature rises to 93 DEG C, clutch solenoid power-off, frictional disk is fitted with driving disc spacing pressing, and water pump runs with integral drive speed. When engine water temperature is lower than 83 DEG C, clutch solenoid is energized, and frictional disk is fitted with driving disc spacing pressing, and water pump drops to transfer rotating speed from integral drive rotating speed. As can be seen here, the operation of water pump is entirely the adaptation protean work process requirement of electromotor such that it is able to well protects electromotor, makes electromotor safe operation all the time.
Beneficial effect: the anti-inefficacy speed governing electric control pump of one described in the utility model, car engine cooling system energy-saving effect after improvement is obvious, Modern Traffic transport can be widely used in, Shipping, agricultural machinery and generating set etc., by the mechanical water pump in the electromotor of every field, rise to a new level and modern advanced stage, so that electromotor also rises to a new level and modern advanced stage, make the work of engine-cooling system, more scientific, it is more suitable for the needs of engine working process, more energy efficient, safer, more environmental protection.Therefore, the present invention is again an environmental protection engineering, so the present invention at Engine Industry spread, will bring up one no small progress of Engine Industry.
