Abstract
The utility model discloses a DC (direct current) motor with an electromagnetic clutch, which includes a motor main body 1, a motor lower cover 2, a worm gear 3, a gasket 4, a driving friction plate 5, a driven motor shaft 6, a driven friction plate 7, a coil 8, an iron core 9, and a motor upper cover 10, wherein the motor main body 1 is connected with the worm gear 3; the worm gear 3 is connected with the driving friction plate 5 through embedded teeth at the upper end of the worm gear 3; the driven motor shaft 6 and the driven friction plate 7 are fixed together in an interference fit manner; the electromagnetic coil 8 is fixed with the iron core 9; and the iron core 9 is fixed with the motor upper cover 10. The DC motor effectively solves a problem with motor clutching. Compared with the prior art, the DC motor has the advantages of simple structure, small volume, small rotational inertia, fast response, long service life, short-range manual operation, and capabilities of centralized control and remote control. The DC motor is suitable for popularization and application in business cars.
Description
Technical field
The utility model relates to a kind of motor of charged magnetic clutch.
Background technology
At present, domestic direct current machine generally adopts worm and gear to slow down.Do not have clutch function, as be used in the automatic door unit, in case of emergency, automatically-controlled door is not that can't to open be exactly to crush the passenger.Domestic present way is to add a cover clutch is controlled automatically-controlled door by handle or drag-line emergency release.As can only be in car with handle the emergency release relevant criterion of release (do not meet outside the Che Neiche can both), as use drag-line, the Che Neiche loong shunt is to release mechanism, its complex structure, fails extensively to promote at the failure rate height.
Summary of the invention
At the deficiencies in the prior art, the purpose of this utility model is: because the limitation of manual slide, commercial vehicle adopts power-operated sliding door will become trend, the critical component of power-operated sliding door is exactly a drive motors, because direct current machine does not have clutch function at present, need add the cover clutch, the promotion and application that cause the cost height, volume is big, installation is inconvenient, are unfavorable for power-operated sliding door, the utility model provides a kind of direct current machine of charged magnetic clutch function, has effectively solved the problems referred to above.
Technical scheme of the present invention is:
A kind of direct current machine of charged magnet clutch, it is characterized in that: it is by motor main body, motor lower cover, worm gear, pad, active friction plate, slave motor axle, constitute from movable friction plate, solenoid, iron core, motor loam cake, described motor main body links to each other with described worm gear, described worm gear links to each other with described active friction plate by the tooth embedding of its upper end, described slave motor axle and describedly be fixed together by interference fit from movable friction plate, described solenoid and described iron core are fixed together, and described iron core and described motor loam cake are fixed together.
The direct current machine of above-mentioned charged magnet clutch, it is further characterized in that: it also comprises pad, described pad is contained in the middle of described worm gear and the described active friction plate; Described motor main body links to each other with described worm gear by worm screw; Described active friction plate and be Armco iron and friction material assembly from movable friction plate.
Beneficial effect of the present invention:
The utility model discloses a kind of motor of charged magnetic clutch function, effectively solved other clutch, cost height, volume be big, it is inconvenient to install, and inconvenient centralized control and far distance controlled, is unfavorable for the problem of the promotion and application of power-operated sliding door.The utility model provides a kind of direct current machine of charged magnetic clutch function of novelty, has solved the problems referred to above effectively, for power-operated sliding door is laid a good foundation at Chinese large-scale promotion application.

Embodiment
Below in conjunction with drawings and Examples the present invention is further described.
As shown in Figure 1 and Figure 2, the direct current machine of the charged magnetic clutch function of present embodiment, clutch is in the lower cover of direct current machine, and motor is by the motor main body 1 that contains worm screw, motor lower cover 2, worm gear 3, pad 4, active friction plate 5, slave motor axle 6, constitute from movable friction plate 7, solenoid 8, iron core 9, motor loam cake 10.Motor main body 1 links to each other with worm gear 3 by worm screw 11, worm gear 3 links to each other with active friction plate 5 by the tooth embedding of its upper end, slave motor axle 6 be fixed together by interference fit from movable friction plate 7, solenoid 8 is fixed together with iron core 9, iron core 9 is fixed together with motor loam cake 10.It is middle to prevent that grease engaging friction sheet and dust from entering worm gear with active friction plate 5 that pad 4 is contained in worm gear 3.When rotor rotated, after solenoid 8 energisings, iron core 9 produced electromagnetic attractions, with active friction plate 5, inhale to iron core 9 from movable friction plate 7, relied on active friction plate 5, from the frictional force between the movable friction plate 7, and slave motor axle 6 is rotated with worm gear 3.During solenoid 8 outages, iron core 9 demagnetizations do not have electromagnetic attraction, and active friction plate 5 restores under the effect of gravity, and clutch promptly loses the effect of carry-over moment, and slave motor axle 6 does not rotate with worm gear 3, reaches clutch function.
Though the present invention with preferred embodiment openly as above, they are not to be used for limiting the present invention, anyly have the knack of this skill person, without departing from the spirit and scope of the invention, certainly when can doing various variations or retouching, but belong to the present invention's protection range equally.What therefore the present invention should be defined with the application's claim protection range is as the criterion.
