Directional terms as referred to in the following examples, for example: up, down, left, right, front or rear, etc., are simply directions with reference to the drawings. Accordingly, the directional terminology is used for purposes of illustration and is in no way limiting.
The emergency protection type water pump clutch shown in fig. 1 and 2 mainly includes a shaft coupling bearing 1, a base 2, a driving mechanism 3, a driven mechanism, a coil assembly 4, a protection assembly 9, and the like.
Wherein the base 2 is normally fixed to the block of the engine. The shaft connecting bearing 1 is arranged in the base 2 in a penetrating mode, so that the shaft connecting bearing 1 penetrates through the base 2 and is located in the center of the shaft connecting bearing 1, and the peripheral surface of the middle of the shaft connecting bearing 1 is in contact with the inner wall of the base 2 to achieve fixed connection; one end of the shaft coupling bearing 1 extends into the cooling circuit of the engine and will mount an impeller at that end (defined as the outer end).
The driving mechanism is used for providing power for the driven mechanism and comprises a driving wheel 5 (the driving wheel 5 is positioned on the other side of the base 2 and deviates from the end part for installing the impeller, and the outer peripheral surface of the driving wheel 5 is provided with meshing teeth or belt grooves which can be meshed with other structures or can be used for installing a belt to be connected with an engine, so that the engine is utilized to drive the driving wheel 5 to rotate), an end cover 8 (deviating from the shaft connecting bearing 1) arranged on one side of the driving wheel 5, a partition plate 6 (the partition plate 6 is connected with the driving wheel 5 and the end cover 8 through a plurality of fasteners such as bolt pairs) arranged between the driving wheel 5 and the end cover 8 and a valve plate assembly 62. An oil storage chamber 61 is formed between the partition plate 6 and the driving wheel 5, and an accommodating space is formed between the partition plate 6 and the end cover 8, so that the valve plate assembly 62 is arranged in the oil storage chamber 61; at least one oil outlet 63 and at least one oil return channel 64 are arranged on the partition plate 6, and the oil storage chamber 61 is communicated with the accommodating space through the oil outlet 63.
The driven mechanism is used for driving the impeller to rotate through the shaft connecting bearing 1, and comprises a driven shaft 3 which is arranged at one end part (the end part adjacent to the driving wheel 5) of the shaft connecting bearing 1 and is connected with the driving wheel 5 through a bearing 51 (at the moment, the driven shaft 3 penetrates through the driving wheel 5, and the bearing 51 is arranged between the driven shaft 3 and the driving wheel 5, so that when the driven shaft 3 rotates, the rotation of the impeller can be synchronously carried out through the shaft connecting bearing 1, but the base 2 fixedly connected with the middle part of the shaft connecting bearing 1 does not rotate), and a driven plate 7 which is connected (usually fixedly connected) with the driven shaft 3 and is matched with an end cover 8. Specifically, a first tooth groove is formed in the edge of the inner wall of the end cover 8, a second tooth groove matched with the first tooth groove is formed in the edge of the driven plate 7, and the first tooth groove and the second tooth groove are combined to form a working cavity 71 (that is, the working cavity 71 is formed between the end cover 8 and the driven plate 7); the working chamber 71 and the oil reservoir chamber 61 communicate through the oil return passage 64. When the driving wheel 5 rotates under the action of external force (from an engine), the end cover 8 is driven to synchronously rotate, the driven plate 7 is driven to rotate under the action of silicon oil, and then the impeller at the outer end part of the shaft connecting bearing 1 is driven to rotate through the driven shaft 3 and the shaft connecting bearing 1.
The coil assembly 4 is arranged on the peripheral surface of the base 2 and used for enabling the valve plate assembly 62 to open or close the oil outlet 63 by electrifying or powering off; it is preferable to close the oil return passage 64 when opening the oil outlet 63 and to open the oil return passage 64 when closing the oil outlet 63, so as to improve the efficiency of oil return or oil discharge. In the present embodiment, the coil block 4 includes a base (fixed on the circumferential surface of the base 2 in a conventional manner) fitted over the base 2, a mounting groove 41 (the mounting groove 41 is annular) opened on the base and facing the partition 6, and an electromagnetic coil 42 disposed in the mounting groove 41; the coil assembly 4 also typically includes a connector disposed on the base and connected to the electromagnetic coil 42 so that it may be externally connected to a power source. When the coil component 4 is electrified, the coil component generates magnetic force to act on the valve plate assembly 62, so that the valve plate assembly opens the oil outlet 63; when the coil block 4 is de-energized, the magnetic force disappears and the valve sheet assembly 62 returns to its original shape to block the oil outlet 63.
The basic working principle of the water pump clutch is as follows:
the engine is directly connected with the driving wheel 5 through a belt, the driving wheel 5 can rotate along with the engine, one end of the shaft connecting bearing 1 extends into a cooling loop of the engine and is provided with an impeller, the driven plate 7 is connected with the shaft connecting bearing 1 through the driven shaft 3, and the driving wheel 5, the end cover 8 and the partition plate 6 are connected with the driven shaft 3 through a bearing 51;
the silicone oil in the oil storage chamber 61 is used as a medium for transferring force, when the oil outlet 63 is opened by the coil component 4 absorbing the valve plate assembly 62, the silicone oil enters the working chamber 71 from the oil storage chamber 61 (i.e. huge shearing force is generated by the structure of the tooth grooves and the viscosity of the silicone oil), so that the driving wheel 5 drives the driven plate 7 and the shaft connecting bearing 1 to follow up through the partition plate 6 and the end cover 8, further drives the impeller to rotate, the circulation speed of the cooling liquid in the engine is increased, and the purpose of increasing cooling is achieved; the silicone oil in the tooth socket moves to the periphery of the tooth socket due to the centrifugal force caused by rotation, and pressure is generated under the action of the centrifugal force to extrude the silicone oil into the oil return channel 64 and return to the oil storage chamber 61 to form circulation; after the valve plate assembly 62 closes the oil outlet 63, the silicone oil in the working cavity 71 gradually returns to the oil storage cavity, the shearing force generated after the silicone oil between the tooth grooves is reduced, the rotating speed of the shell and the end cover is reduced, the rotating speed of the impeller is reduced, and the circulating speed of the cooling liquid is also reduced.
In the application, the emergency protection type water pump clutch further comprises a protection assembly 9, wherein the protection assembly 9 comprises a fixed rod 91 and a limiting block 92, the fixed rod 91 is inserted into the end cover 8 and the driven shaft 3 along the axial lead direction of the shaft connecting bearing 1 and penetrates through the end cover, and the outer end of the fixed rod is provided with a clamping joint matched with the limiting block 92; the limiting block 92 is detachably sleeved on the fixing rod 91 and is located outside the end cover 8. The shaft coupling bearing 1 (i.e., the inner end surface of the shaft coupling bearing 1) is provided with a fixing hole 911 extending along the axial line direction and matching with the fixing rod 91. In this embodiment, the end cap 8 is further provided with a positioning block 81 (at the center of the outer surface thereof) to rotate synchronously therewith, and the positioning block 81 may be independent and mounted on the outer surface of the end cap 8 by conventional methods (such as screw connection, snap connection, etc.), or may be integrated with the end cap 8; the positioning block 81 not only plays a role in positioning the fixing hole 911, but also is used for switching the fixing rod 91 to ensure that the fixing rod can rotate along with the end cover 8, at the moment, the fixing rod 91 penetrates through the positioning block 81, and the limiting block 92 is positioned on the outer side of the positioning block 81; the connection mode of the fixing rod 91, the positioning block 81 and the fixing hole 911 is conventional, as long as the end cover 8, the positioning block 81, the fixing rod 91 and the shaft connecting bearing 1 can synchronously rotate after the fixing rod 91 is inserted into the fixing hole 911, and the cross sections of the positioning block 81, the fixing hole 911 and the fixing hole 911 can be set into conventional shapes such as a square shape or connected by threads; therefore, when the driven plate 7 cannot rotate along with the end cover 8 under the action of silicon oil to cause high-temperature alarm, the driving wheel 5 is manually stopped, the limiting block 92 is removed (or the limiting block 92 is directly removed), and after the fixing rod 91 is inserted into the fixing hole 911, the rigid connection between the driving wheel 5 and the shaft connecting bearing 1 is indirectly realized, so that the driving wheel can be immediately restored to a working state under the failure state of the water pump clutch, the damage of an engine caused by the failure of the water pump clutch is prevented, and the service life of the engine is prolonged.
In this embodiment, the driven mechanism further includes a bearing sleeve 52 sleeved outside the bearing 51, and a magnetic ring 53 connected between the bearing sleeve 52 and the driving wheel 5 (the magnetic ring 53 is connected with the driving wheel 5 and the bearing sleeve 52 through threads), and the magnetic ring 53 is located between the electromagnetic coil 42 and the oil storage chamber 61, and plays a role of magnetic conduction. The valve plate assembly 62 comprises an elastic plate 622 clamped between the driving wheel 5 and the partition plate 6, a magnetic attraction plate 621 arranged on the surface of the elastic plate 622 and facing the coil component 4, and a valve plate 623 arranged on the other surface of the elastic plate 622 and matched with the oil outlet 63 and the oil return channel 64; the elastic piece 622 is arranged in the oil storage chamber 61, is annular and is arranged coaxially with the shaft connecting bearing 1; the magnetic attraction piece 621 is attracted by the magnetic force to cause the elastic piece 622 to deform, thereby driving the valve plate 623 to axially displace to open or close the oil outlet 63.
In this embodiment, a speed measuring ring 11 is further sleeved on the shaft coupling bearing 1 to measure and feed back the rotating speed of the shaft coupling bearing 1, which is also the rotating speed of the impeller. The edge of the outer side surface of the end cover 8 is also provided with a plurality of heat dissipation ribs 82 which are arranged at intervals. The partition 6 is provided with an oil return groove 65 at the outermost side of the working chamber 71, and the oil return groove 65 communicates with the oil return passage 64.
