Description
Technical field: the utility model belongs to the car engine cooling system technical field, is specifically related to a kind of water pump stepless fan clutch.
Background technique: electromagnetic fan clutch is adopted in the cooling of existing motor car engine more, separate to come work by the direct adhesive of fan and water pump, because the unexpected adhesive of fan loads, can cause very big impact force to motor, even influence the normal operation of motor, and also there are complex structure, defect of high cost.
Summary of the invention: the purpose of this utility model provides a kind of simple in structure, cost is low, impact force is little water pump stepless fan clutch.
The technical solution of the utility model is: a kind of water pump stepless fan clutch, comprise belt pulley, fan fixed disk and water pump, and the shaft connecting bearing axle that it is characterized in that being installed in the water pump bearing hole is a hollow shaft, establishes temperature transducer in its hole; One end of shaft connecting bearing axle is connected on the impeller of water pump, and the other end is fixed on belt pulley respectively and is connected fan fixed disk with bearings; On the end face of the belt pulley corresponding, establish spring sheet support and connection magnetic conduction iron pan with fan fixed disk; Establish some embedding grooves on the fan fixed disk end face corresponding, soft iron sheet and fixed permanent magnet are installed successively, on the shaft connecting bearing axle between magnetic conduction iron pan and the corresponding belt pulley, be provided with the slide block that links to each other with the push rod of temperature transducer with the magnetic conduction iron pan; A device of between shaft connecting bearing axle and slide block, limiting.
Wherein, described limit stoper is made up of restraining groove on the shaft connecting bearing axle and the limited post on the slide block, and limited post is positioned at restraining groove.
Owing to adopt technique scheme, temperature transducer water direct and in the water pump contacts, and temperature control is accurate; Along with variation of temperature, in the distance that changes under the effect of push rod, slide block and spring sheet between magnetic conduction iron pan and the fan fixed disk, under the effect of magnetic force, realize stepless transmission, fan reaches stepless change; Have simple in structure, cost is low, impact force is little, the advantage of fan continuously variable.
Description of drawings: technical solutions of the utility model are described further below in conjunction with the drawings and specific embodiments.Fig. 1 is a structural representation of the present invention.Fig. 2 is the structural representation between push rod of the present invention, slide block, the shaft connecting bearing axle.
Embodiment: with reference to figure 1, Fig. 2.A kind of water pump stepless fan clutch comprises belt pulley 1, fan fixed disk 2 and water pump 3, and the shaft connecting bearing axle 4 that is installed in water pump 3 bearing holes is a hollow shaft, establishes temperature transducer 5 in its hole; One end of shaft connecting bearing axle 4 is connected on the impeller of water pump, and the other end is fixed on belt pulley 1 respectively and is connected fan fixed disk 2 with bearings; On the end face of the belt pulley 1 corresponding, establish spring sheet 6 support and connection magnetic conduction iron pans 7 with fan fixed disk 2; Establish some embedding grooves on the corresponding end face of fan fixed disk 2 and magnetic conduction iron pan 7, soft iron sheet 8 and fixed permanent magnet 9 are installed successively, on the shaft connecting bearing axle 4 between the belt pulley 1 of magnetic conduction iron pan 7 and correspondence, are provided with the slide block 11 that links to each other with the push rod 10 of temperature transducer 5; A device of between shaft connecting bearing axle 4 and slide block 11, limiting.Limit stoper is made up of the limited post on restraining groove on the shaft connecting bearing axle 4 and the slide block 9, and limited post is positioned at restraining groove.
During work, temperature transducer water direct and in the water pump contacts, along with water temperature raises, it is close gradually to fan fixed disk to promote the magnetic conduction iron pan by push rod, slide block, and belt pulley drives in the magnetic field of the permanent magnet of magnetic conduction iron pan on fan fixed disk and the formation of soft iron sheet and rotates cutting magnetic line, himself produces foucault current, foucault current produces new magnetic field, and under the effect of magnetic force, fan fixed disk and magnetic conduction iron pan flexibly connect rotation and progressively increase; When water temperature reduced, at the equal return gradually of the effect bottom slide block of spring sheet, push rod, the distance between magnetic conduction iron pan and the fan fixed disk increased, and magnetic force weakens, and the fan fixed disk rotating speed reduces, thereby reaches stepless change.
