The model utility content:
The purpose of this utility model is exactly the deficiency at prior art, and provide a kind of wear-resisting type clutch, when it gets back to original position at annular piston, can be at once with active friction plate with separate from movable friction plate, reduce active friction plate and from the friction between the movable friction plate, improved the working life of clutch.
Technology solution of the present utility model is as follows:
A kind of wear-resisting type clutch, comprise the clutch rotating shaft, active friction plate, from movable friction plate, hub in the clutch, the outer hub of clutch and Returnning spring, hub is connected in the clutch rotating shaft in the clutch, the outer hub of clutch and clutch rotating shaft are shaped to one, active friction plate and alternately be sleeved in the clutch on the hub from movable friction plate, active friction plate and from movable friction plate in clutch outside hub and the clutch between the hub, the internal tooth of active friction plate is meshed with the external tooth of the pinion stand of the interior hub of clutch, the flexible packing ring of pinion stand upper sleeve of hub in the described clutch, each elastic washer is clamped in two between the movable friction plate.
Preferred as technique scheme, described elastic washer is wave washer, it is along circumferencial direction undulate structure; The active friction plate sleeve is in the inner ring of elastic washer.
Preferred as technique scheme, fixedly have in the described clutch rotating shaft axle with collar, be inserted with spring seat, Returnning spring and annular piston, Returnning spring one end is put forth effort on spring seat, the other end is put forth effort on annular piston, spring seat is pressed against spool with on the collar.
Preferred as technique scheme describedly forms projection from the movable friction plate outer ring, in the protruding sleeve elongated slot that hub forms outside clutch.
Preferred as technique scheme, hub is movably connected by bearing and clutch rotating shaft in the described clutch.
The beneficial effects of the utility model are:
The pinion stand upper sleeve elastic washer of its hub in clutch, elastic washer on the outer ring of active friction plate, each elastic washer be clamped in per two between the movable friction plate; Like this when annular piston is got back to original position, by the back stretch of elastic washer, can be at once with active friction plate with separates from movable friction plate, minimizing active friction plate and from the friction between the movable friction plate has improved the working life of clutch.

Among the figure: 1, clutch rotating shaft; 11, axle collar; 12, spring seat; 2, active friction plate; 3, from movable friction plate; 31, projection; 4, hub in the clutch; 41, pinion stand; 5, the outer hub of clutch; 51, elongated slot; 6, Returnning spring; 7, elastic washer; 8, annular piston; 9, bearing; 10, retainer ring.
Embodiment:
Embodiment: see shown in Fig. 1 to 5, a kind of wear-resisting type clutch, comprise clutch rotating shaft 1, active friction plate 2, from movable friction plate 3, hub 4 in the clutch, the outer hub 5 of clutch and Returnning spring 6, hub 4 is connected in the clutch rotating shaft 1 in the clutch, the outer hub 5 of clutch is shaped to one with clutch rotating shaft 1, active friction plate 2 and alternately be sleeved in the clutch on the hub 4 from movable friction plate 3, active friction plate 2 and from movable friction plate 3 in clutch outside hub 4 and the clutch between the hub 5, the internal tooth of active friction plate 2 is meshed with the external tooth of the pinion stand 41 of the interior hub 4 of clutch, the flexible packing ring 7 of pinion stand 41 upper sleeves of hub 4 in the described clutch, elastic washer 7 is on the outer ring of active friction plate 2, be that active friction plate 2 sleeves are in the inner ring of elastic washer 7, each elastic washer 7 be clamped in per two between the movable friction plate 3, wherein an elastic washer 7 on the limit is clamped in from movable friction plate 3 and is fixed on outside the clutch between the retainer ring on the hub 5 10.
Described elastic washer 7 is wave washer, and it is along circumferencial direction undulate structure.
Fixedly have in the described clutch rotating shaft 1 axle with collar 11, be inserted with spring seat 12, Returnning spring 6 and annular piston 8, Returnning spring 6 one ends are put forth effort on spring seat 12, the other end is put forth effort on annular piston 8, spring seat 12 is pressed against on the axle usefulness collar 11.
The described projection 31 that forms from movable friction plate 3 outer rings is in the protruding 31 sleeves elongated slot that hub 5 forms outside clutch 51.
Hub 4 is movably connected by bearing 9 and clutch rotating shaft 1 in the described clutch, and its middle (center) bearing 9 is the ball bearing of no outer ring and inner ring, and bearing 9 both sides are provided with spacing back-up ring, and spacing back-up ring is fixed in the clutch rotating shaft 1.
Working principle: enter annular piston 8 behind the oil duct of clutch rotating shaft 1 and promote annular pistons 8 thereby enter when fluid, it is innermost from movable friction plate 3 to make that annular piston 8 promotes, make all be pressed against with active friction plate 2 from movable friction plate 3, at this moment per two is compression from the elastic washer 7 between the movable friction plate 3, and Returnning spring 6 is also compressed, at this moment just just transmission of power give hub 4 in the clutch, the gear transmission that the outside by hub in the clutch 4 forms is gone out; When fluid refluxes, elastic force by Returnning spring 6, annular piston 8 is resetted, at this moment, because elastic washer 7 is on the outer ring of active friction plate 2, by the back stretch of elastic washer 7 self, push open from movable friction plate 3 for that it is adjacent two, make active friction plate 2 with separate fast from movable friction plate 3, this reduces active friction plate 2 and from the friction between the movable friction plate 3, the working life of having improved clutch.
