In the middle left part and the water pump flange plate interference fit of the shaft connecting bearing of cooling waterpump, interference fit has the flange land on the cylindrical of water pump flange plate, is wound with coil on the flange land, and this coil is connected with car load power supply and ECU; According to the instruction of ECU, whether decision switches on.
The inner ring interference fit of the left end of the shaft connecting bearing of cooling waterpump and two-row ball bearing, the rank piece on inner belt pulley right side is corresponding with coil on the flange land.
Further, be provided with the dust-sealing cover plate, this dust-sealing cover plate in the left side of described two-row ball bearing
CardOn inner belt pulley.With the two-row ball bearing of protection motor under rugged environment work,
Adopt main effect of the present invention to be, operating conditions and different running environment that can be different according to motor, whether in good time adjusting water pump works, and has improved the running temperature of motor greatly, make burning more reasonable, thereby greatly reduce the oil consumption and the discharging of car load.
Description of drawings
Fig. 1 is the schematic representation of traditional water pump pulley assembly;
Fig. 2 is a structural representation of the present invention.
Embodiment
The present invention is further illustrated below in conjunction with accompanying drawing.
A kind of automobile engine cooling water pump belt pulley assembly referring to shown in Figure 1 comprises the belt pulley of being made up of inner belt pulley 11 and external skin belt wheel 12 1, and the endoporus interference fit of the cylindrical of inner belt pulley and external skin belt wheel forms an integral body; Endoporus at inner belt pulley 11 is provided with two-row ball bearing 3, is connected with rank piece 7 on the right side of inner belt pulley cylindrical, is bonded with lock dog 8 on the rank piece; Be provided with return spring 71 in rank piece 7, an end of this return spring is fixed on the right side of left side, the other end and the rank piece 7 of rank piece 7 and fits;
The middle left part of the shaft connecting bearing 9 of cooling waterpump and water pump flange plate 10 interference fit, interference fit has flange land 6 on the cylindrical of water pump flange plate, is wound with coil 5 on the flange land, and this coil is connected with car load power supply and ECU; According to the instruction of ECU, whether decision switches on;
The left end of the shaft connecting bearing 9 of cooling waterpump and the inner ring interference fit of two-row ball bearing 3, the rank piece 7 on inner belt pulley 11 right sides is corresponding with the coil 5 on the flange land 6.
Further, be provided with dust-sealing cover plate 4 in the left side of described two-row ball bearing 3, this dust-sealing cover integrated circuit board is on inner belt pulley 11, with the two-row ball bearing of protection motor under rugged environment work.
For working life of guaranteeing cooling waterpump belt pulley assembly and reduce axial dimension, two-row ball bearing 3 of design in inner belt pulley 11, the cylindrical interference fit of endoporus and two-row ball bearing 3 by inner belt pulley 11, shaft connecting bearing 9 interference fit of two-row ball bearing 3 endoporus and cooling waterpump;
Be the weight of saving the material of coil 5 and alleviating the belt pulley assembly, coil 5 is empty body of its inner formation when twining.
Flange land 6 and water pump flange plate 10 interference fit, rank piece 7 and inner belt pulley 11 are connected by bolt, and lock dog 8 is bonded in to be held in the mouth on the piece 7, hold in the mouth piece 7, lock dog 8 different instruction according to ECU, belt pulley 1 is connected with flange land 6 or disconnects, make water pump play switching function.
When engine cold-starting or low speed and load work, engine-cooling system plays negative effect, so given signal of ECU, give coil 5 energisings, produce electromagnetic action, rank piece 7 is moved towards the left side, and the lock dog 8 that rank piece 7 drives on it moves, and makes lock dog 8 leave flange land 6.At this moment, belt pulley 1 only drives two-row ball bearing 3 and rotates, and all the other parts are motionless, and the water pump pulley assembly is equivalent to an idle pulley, and water pump is not worked, and engine water temperature is elevated to optimum working temperature fast.
When engine water temperature during than higher or high speed high loaded process, need to start cool cycles, so the given signal of ECU, give coil 5 outages, 5 pairs of ranks of coil piece, 7 no electromagnetic actions are located at the rank piece
7The effect of inner return spring 71 promotes lock dog 8 down and moves to flange land 6, lock dog 8 embeds in the flange land 6, the inside belt pulley 11 of belt pulley 1 is linked into an integrated entity by rank piece 7 and lock dog 8 with flange land 6, belt pulley 1 drives water pump and rotates, cooling system begins circulation, has guaranteed that engine operating temperature is unlikely too high.
The present invention can be different according to motor operating conditions and different running environment, whether in good time adjusting water pump works, and has improved the running temperature of motor greatly, makes burning more reasonable, engine consumption, discharging are reduced, reach favorable cooling effect again.
Usually the structure of engine water pump belt pulley as shown in Figure 1: water pump pulley 21 is connected with the water pump flange plate by the mounting hole 22 of design on it.Water pump pulley is connected by belt with engine crankshaft belt pulley.When ato unit, crankshaft rotating, crank pulley passes torque to water pump pulley by belt, and water pump pulley drives the water pump rotation, for cooling system provides power, final cooled engine.
