Embodiment
As shown in Figure 1, the utility model comprises the pump housing 1, swash plate 2 and axle 10, piston chamber and multiple plunger cavity is provided with in the described pump housing 1, the plunger 4 that can slide along its inwall is provided with in each described plunger cavity, the cavity of described plunger 4 is provided with spring 5, the described pump housing 1 has and can be communicated with described piston chamber and the via 7 of plunger cavity described in each, one end of described axle 10 is passed described piston chamber and stretches in the pump housing 1, described swash plate 2 is fixedly mounted on axle 10, described swash plate 2 is positioned at the pump housing 1, thrust-bearing 3 is provided with between described swash plate 2 and plunger 4, the spool 8 that can slide along its inwall is provided with in described piston chamber, Returnning spring 6 is provided with between described spool 8 and the pump housing 1, described spool 8 has the conduction trough 9 that can be communicated with via 7, described axle 10 is through Returnning spring 6 and spool 8.
As shown in Figure 1, the end of described axle 10 is provided with bearing 11, and described bearing 11 is positioned at the pump housing 1, and the outer ring of described bearing 11 is fixedly connected with the pump housing 1, and the inner ring of described bearing 11 is fixedly connected with axle 10; Bearing 11, for back shaft 10, guarantees the relative movement between axle 10 and the pump housing 1.
As shown in Figure 1, be provided with exterior seal ring 12-1 and inner seal ring 12-2 between described spool 8 and the pump housing 1, described exterior seal ring 12-1 and inner seal ring 12-2 lays respectively at the both sides of conduction trough 9; The setting of exterior seal ring 12-1 and inner seal ring 12-2 can prevent hydraulic oil from leaking outside.
In the present embodiment, the described pump housing 1 is cylindrical pump, and multiple plunger cavity is circumferentially evenly laid.
In the present embodiment, described swash plate 2 is connected with axle 10 key, easy to connect, fixing reliable.
Working principle of the present utility model is: the pump housing 1 is the drive end of clutch, and axle 10 is the driven end of clutch.When needs clutch separation, spool 8 compression reseting spring 6 is made by operating mechanism at the outer end place of spool 8, spool 8 to left-hand move to conduction trough 9 be communicated with completely with via 7 time, complete conducting between each plunger cavity, plunger 4 retractable, the pump housing 1 is free to rotate relative to axle 10, achieves clutch and is separated completely.When needs clutch in conjunction with time, remove operating mechanism to the effect of spool 8, then Returnning spring 6 promotes spool 8 and moves right, conduction trough 9 and via 7 stagger, because spool 8 blocks each via 7 completely, so hydraulic oil can not flow out in the cavity of each plunger 4, plunger 4 can not be retracted, then swash plate 2 can not rotate relative to the pump housing 1, achieves clutch and combines completely (as shown in Figure 1).When needs clutch quasi integration, make conduction trough 9 and the conducting of via 7 part, i.e. part blocks via 7, running of hydraulic power oil is subject to certain resistance, produces corresponding oil pressure, and axle 10 produces corresponding moment of torsion relative to the pump housing 1, is be incomplete bonding state.
The above; it is only preferred embodiment of the present utility model; not the utility model is imposed any restrictions; every above embodiment is done according to the utility model technical spirit any simple modification, change and equivalent structure transformation, all still belong in the protection domain of technical solutions of the utility model.
