Embodiment 1

[0024] Embodiment 1: see figure 1 .

[0025] An electromagnetic torsion spring driven clutch water pump operated by a multi-disc clutch assembly, including a shaft-connected bearing 1, and a driven wheel 12 is installed on one end of the shaft-connected bearing 1 with interference, and the driven wheel 12 is pivotally connected to the driving wheel 7 through the bearing 13 [ Pulley], the electromagnet assembly 5 is installed in the middle part of the shaft-connected bearing 1, where the electromagnet assembly 5 can rotate relative to the shaft end of the shaft-connected bearing 1; the electromagnet assembly 5 includes an iron core and is arranged in the iron core The electromagnetic coil, the iron core is cast as an integral body with the shell 4 in the form of an insert, and the material is soft magnetic material such as 08F or Q235, and the shaft-connected bearing 1 is installed on the inner wall of the insert with interference; the suction part 6 is installed on the electro...

Embodiment 2

[0028] Example 2, see Figure 1-2 .

[0029] Others are the same as in Embodiment 1, except that the suction part 6 includes a suction disc 18, a friction disc 20, and a manipulation sheet 19 arranged between the suction disc 18 and the friction disc 20, and the manipulation tab 19 is manipulated The claw is fixed on the pin at one end of the torsion spring 9, and 6 grooves are evenly arranged on the circumferential end surface of the suction disc 18, and 6 pins are evenly arranged on the circumferential inner end surface of the friction disc 20 accordingly; 18 and the surface of the friction disc 20 include a nitride layer; a wear-reducing bushing is set between the suction disc 18 and the driven pulley 12;

[0030] , the working principle is similar to that of Embodiment 1, and will not be repeated here.

Abstract

The invention is an electromagnetic torsion spring driven clutch device operated by a multi-disc clutch assembly, including a shaft-connected bearing, a driven wheel, a driving wheel, an electromagnet assembly, a suction part, a wave spring retaining ring, a wave spring, and a suction part Including the control piece, it is characterized in that: the driven wheel and the load-bearing part are connected by splines, the end face of the driven wheel and the load-bearing part is fitted with a driven wheel back-up ring near the bearing, and the outer diameter of the driven wheel and the load-bearing part is equal. A torsion spring is arranged on the outer circle, and the end of the torsion spring near the bearing protrudes through the bending groove on the bearing part to act on the spline end surface of the driven wheel, and the other end of the torsion spring protrudes through the pin to pass through the driven wheel The control window and the control claw of the control piece adopt this technical scheme, the clutch device has few parts, and the working process is safe and reliable.

Description

technical field [0001] The invention relates to an electromagnetic clutch device, in particular to an electromagnetic torsion spring driven clutch device operated by a multi-plate clutch assembly. Background technique [0002] The Chinese utility model patent whose publication number is CN203926502U discloses "An Electromagnetic Torsion Spring Clutch Utilized by a Multi-disc Clutch Assembly". The torsion spring is located in the torsion spring sleeve and outside the driven wheel. In the free state, the outer diameter of the torsion spring is greater than the diameter of the torsion spring sleeve, and the torsion spring sleeve has pins to link to each other with the operating piece. When the coil is not energized, the suction plate presses the friction plate and the driving wheel, so that the rotation of the control plate causes the rotation of the torsion spring sleeve, and the torsion spring cover plate matched with the torsion spring sleeve drives the pin of the torsion sp...
