Description
Technical Field
The utility model belongs to the technical field of machinery, a lose electromagnetic clutch assembly is related to.
Background
When the engine operates, the cooling liquid needs to be circularly operated to dissipate heat, and the cooling liquid is conveyed by the water pump to circularly flow. When the temperature of the engine rises, the rotating speed of the water pump is increased, so that the cooling liquid is subjected to large circulation; when the temperature of the engine is low, the rotation speed of the water pump is reduced, and the coolant is circulated for a short time. In order to control the rotation of the water pump, it is common to arrange an electromagnetic clutch in the water pump, the electromagnetic clutch is connected with a controller, the controller is provided with a temperature sensor for detecting the temperature of the engine, the temperature sensor sends the detected temperature to the controller, the controller controls the electromagnetic clutch to act according to the received temperature information, the belt pulley drives the water pump rotating shaft to rotate at a high speed when the electromagnetic clutch is powered on, and the belt pulley does not drive the water pump rotating shaft to rotate or drives the water pump rotating shaft to rotate at a low speed when the electromagnetic clutch is powered off. When the water pump electromagnetic clutch with the structure is used, when the electromagnetic clutch breaks down or power failure occurs, the rotating shaft of the water pump cannot rotate, so that the engine cannot be cooled, and the engine is easily caused to be continuously in a high-temperature working state or even burnt out.
Chinese patent literature document discloses an electromagnetic clutch water pump with double friction discs [ application number: CN 201711435760.5; publication No.: 108087094A ], including a main shaft passing through the pump body, one end of the main shaft is fixed with an impeller, the other end is sheathed with a belt pulley sucker and a metal friction disk in turn, a coil iron core component is arranged in the belt pulley sucker, the metal friction disk and the belt pulley sucker are arranged in a relative clearance, one side of the metal friction disk facing away from the belt pulley sucker is fixed with a plane spring and a metal magnetic conductive disk in turn by screws, the plane spring is fixed with the belt pulley sucker at the same time, one side of the metal magnetic conductive disk facing away from the plane spring is fixed with a permanent magnet and a non-metal friction disk in turn, the main shaft is also fixed with an induction driving disk opposite to the non-metal friction disk, and a metal magnetic conductor matched with the permanent magnet to generate eddy current is embedded in the induction driving disk, when the coil iron core component is electrified, the suction force between the metal friction disk, the first magnetic force is larger than the second magnetic force.
The working process of the electromagnetic clutch water pump is as follows: when the coil iron core component is electrified, the metal friction disc is attracted to the belt pulley sucker by magnetic force generated by the coil iron core component, the non-metal friction disc is separated from the induction driving disc, and the induction driving disc and the non-metal friction disc generate relative rotation through magnetic force between the permanent magnet and the metal magnetizer, so that the water pump rotating shaft and the belt pulley rotate in a differential manner, namely the water pump rotating shaft rotates at a low speed; when the coil core component loses power, the first magnetic force disappears, the metal magnetic conduction disc is acted by the second magnetic force to enable the non-metal friction plate to abut against the induction driving disc, and sufficient friction force is generated between the non-metal friction plate and the induction driving disc to enable the induction driving disc and the metal magnetic conduction disc to synchronously rotate, namely, the water pump rotating shaft and the belt pulley synchronously rotate at high speed.
In the electromagnetic clutch water pump, the non-metal friction plate is pressed into the concave cavity of the metal magnetic conduction plate, and the outer wall of the non-metal friction plate is tightly matched and fixed with the inner wall of the concave cavity. In order to fix firmly, most of the non-metal friction plates are embedded into the metal magnetic conduction plate, only a small part of the non-metal friction plates protrudes to be capable of rubbing with the induction driving plate to generate friction force, when the friction plates of the protruding part are abraded, the induction driving plate can be directly contacted with the metal magnetic conduction plate, and friction slip can be generated between the metal magnetic conduction plate and the induction driving plate, so that synchronous rotation cannot be formed between the belt pulley and the water pump rotating shaft, the electromagnetic clutch cannot enable the water pump rotating shaft to rotate at high speed when the coil iron core assembly is electrified or deenergized, the electromagnetic clutch fails to be normally used, and the service life of the electromagnetic clutch.
The common method for prolonging the service life is to increase the thickness of the friction plate, but the raw material cost is increased, the distance between the permanent magnet and the induction driving disc is increased, the second magnetic force generated between the permanent magnet and the induction driving disc is weakened, the weakening of the second magnetic force can reduce the friction force between the nonmetal friction plate and the induction driving disc, and the friction plate is easy to slip due to the overlarge thickness. Or the friction plate is replaced within a certain time, but the non-metal friction plate and the magnetic metal plate are installed in an interference manner, so that the disassembly, the assembly and the replacement are inconvenient, and the dimensional accuracy of the cavity of the magnetic metal plate is easy to change in the disassembly and the assembly process. If the assembly error between the outer wall of the non-metal friction plate and the inner wall of the cavity is large, the non-metal friction plate is abutted to the induction driving disc, relative sliding occurs between the outer wall of the non-metal friction plate and the inner wall of the cavity, the electromagnetic clutch cannot be normally used, and the service life of the electromagnetic clutch cannot be well prolonged by replacing the friction plate.
