Such as Fig. 2, shown in Figure 6, the oil circuit control of the second mode of execution of the present invention is: one road pilot pressure oil enters the first radial direction oil 34a of the second axle 34 from the radial direction oil 35a on the second axle transparent cover 35, enter the second radial direction oil 34c by the first axial oil duct 34b on the second axle 34, this road pilot pressure oil leads to the first working oil oil pocket 46 of first piston cylinder; Another road pilot pressure oil comprises as shown in Figure 6 the first control oil pipe 41a, the second control oil pipe 41b via control oil pipe 41() enter respectively the 3rd radial direction oil 1e on the brake axle 1, the 6th radial direction oil 52b of the first axle 52, thereby enter respectively the second working oil oil pocket 48 of the second piston cylinder via the 3rd radial direction oil 1e, enter the 3rd working oil oil pocket 47 of the 3rd piston cylinder via the 6th radial direction oil 52b.Because the pilot pressure oil of first piston cylinder, the second piston cylinder and the 3rd piston cylinder is all the pressure oil of the second axle 34 sides, three's oil pressure equates, be easy to coordinate control, therefore correspondent equal is distinguished in the displacement of first piston cylinder and the 3rd piston cylinder, the second piston cylinder, and has realized only depending on an operating oil pressure to control simultaneously the purpose of three piston movements.Thus, mutually corresponding coordinations of the operating mode of the first piston cylinder of speed regulating mechanism, the operating mode of the 3rd piston cylinder and the second piston cylinder of arrestment mechanism, the oil slick thickness that can change simultaneously by change control-oil pressure size between the dynamic and static friction plate of the master of speed regulating mechanism, oil slick thickness size between driven friction and arrestment mechanism is big or small.When the oil slick thickness of 24 of the active friction plate 25 of speed regulating mechanism and driven friction reduces, realization be to compress operating mode, thereby can effective communication power; The oil slick thickness that the movable friction plate 8 of the arrestment mechanism that this moment is corresponding and static friction sheet are 10 increases, realization be to separate operating mode, thereby can reduce braking moment.Vice versa.

The working procedure of the second mode of execution of the present invention is: when system was oily without pilot pressure, the movable friction plate 8 of arrestment mechanism, static friction sheet 10 were compressed fully by the second loaded spring 18.Meanwhile, the active friction plate 25 of speed regulating mechanism, driven friction 24 are separated fully, and at this moment, the sticking transmission device of brake type liquid of the present invention is in the full application of brake operating mode; When there is pilot pressure oil in system, control oil enters respectively the first, the 3rd piston cylinder of speed regulating mechanism and the second piston cylinder of arrestment mechanism from the oil circuit of the second axle 34 sides, adjust simultaneously the oil slick thickness size of 24 of speed regulating mechanism active friction plates 25, driven friction by changing the large I of control-oil pressure, and the oil slick thickness size of 10 of arrestment mechanism movable friction plates 8, static friction sheet.At this moment, the sticking transmission device of brake type liquid of the present invention is in the semi-brake operating mode, thereby both can realize transmitting torque, and electrodeless output rotating speed regulation can apply adjustable resisting moment again, makes system be in for a long time half braking state; When control oil pressure when increasing gradually, the first, the 3rd piston cylinder of speed regulating mechanism is because the effect of controlled system oil pressure, so that the gap of active friction plate 25, driven friction 24 reduces, so the moment of torsion that speed regulating mechanism transmits increases.Meanwhile, the second piston cylinder of arrestment mechanism overcomes the motion of loaded spring power, so that the gap of movable friction plate 8, static friction sheet 10 increases, namely the arrestment mechanism braking torque reduces, and is controlled thereby the speed governing of the system of realization and braking are coordinated mutually; When system's pilot pressure oil pressure is maximum, the active friction plate 25 of speed regulating mechanism, driven friction 24 are compressed fully by oil pressure, movable friction plate 8, the static friction sheet 10 of arrestment mechanism are backed down separation fully by oil pressure simultaneously, at this moment, the sticking transmission device of brake type liquid of the present invention is in zero damped condition, brake axle 1 and the second axle 34 synchronous rotaries.

Such as Figure 10, shown in Figure 14, the oil circuit control of the third mode of execution of the present invention is: one road pilot pressure oil enters the first radial direction oil 34a of the second axle 34 from the radial direction oil 35a on the second axle transparent cover 35, enter the second radial direction oil 34c by the first axial oil duct 34b on the second axle 34, this road pilot pressure oil leads to the first working oil oil pocket 46 of first piston cylinder; Another road pilot pressure oil comprises as shown in figure 14 the first control oil pipe 41a via control oil pipe 41(, the 3rd control oil pipe 41c) enters respectively the 3rd radial direction oil 1e on the brake axle 1, the 7th radial direction oil 1c on the brake axle 1, thereby enter respectively the second working oil oil pocket 48 of the second piston cylinder via the 3rd radial direction oil 1e, enter the 4th working oil oil pocket 49 of the 4th piston cylinder via the 7th radial direction oil 1c, because first piston cylinder, the pilot pressure oil of the second piston cylinder and the 4th piston cylinder is all the pressure oil of the second axle 34 sides, three's oil pressure equates, be easy to coordinate control, so first piston cylinder and the second piston cylinder, the displacement of the 4th piston cylinder is correspondent equal respectively, and has realized only depending on an operating oil pressure to control simultaneously the purpose of three piston movements.Thus, mutually corresponding coordinations of the operating mode of the operating mode of the first piston cylinder of speed regulating mechanism and the second piston cylinder of arrestment mechanism, the 4th piston cylinder, the oil slick thickness that can change simultaneously by changing the oily pressure size of control between the dynamic and static friction plate of the master of speed regulating mechanism, oil slick thickness size between driven friction and arrestment mechanism is big or small.When the oil slick thickness of 24 of the active friction plate 25 of speed regulating mechanism and driven friction reduces, realization be to compress operating mode, thereby can effective communication power; At this moment, the oil slick thickness that the movable friction plate 8 of corresponding arrestment mechanism and static friction sheet are 10 increases, realization be to separate operating mode, thereby can reduce braking moment.Vice versa.

The working procedure of the third mode of execution of the present invention is: when system was oily without pilot pressure, the movable friction plate 8 of arrestment mechanism, static friction sheet 10 were compressed fully by the second loaded spring 18, the 4th loaded spring 9.Meanwhile, the active friction plate 25 of speed regulating mechanism, driven friction 24 are separated fully, and at this moment, the sticking transmission device of brake type liquid of the present invention is in the full application of brake operating mode; When there is pilot pressure oil in system, control oil enters respectively the first piston cylinder of speed regulating mechanism and the second, the 4th piston cylinder of arrestment mechanism from the oil circuit of the second axle 34 sides, adjust simultaneously the oil slick thickness size of 24 of speed regulating mechanism active friction plates 25, driven friction by changing the large I of control-oil pressure, and the oil slick thickness size of 10 of the movable friction plates 8 of arrestment mechanism, static friction sheet.The sticking transmission device of brake type liquid this moment is in the semi-brake operating mode, thereby both can realize transmitting torque, and electrodeless output rotating speed regulation can apply adjustable resisting moment again, makes system be in for a long time half braking state; When control oil pressure when increasing gradually, the first piston cylinder of speed regulating mechanism is because the effect of controlled system oil pressure, so that the gap of active friction plate 25, driven friction 24 reduces, so the moment of torsion that speed regulating mechanism transmits increases.Meanwhile, the second, the 4th piston cylinder of arrestment mechanism overcomes the motion of loaded spring power, so that the gap of movable friction plate 8, static friction sheet 10 increases, namely the braking torque of arrestment mechanism reduces, and is controlled thereby the speed governing of the system of realization and braking are coordinated mutually; When the pilot pressure oil pressure of system is maximum, the active friction plate 25 of speed regulating mechanism, driven friction 24 are compressed fully by oil pressure, movable friction plate 8, the static friction sheet 10 of arrestment mechanism are backed down separation fully by oil pressure simultaneously, at this moment, the sticking transmission device of brake type liquid of the present invention is in zero damped condition, brake axle 1 and the second axle 34 synchronous rotaries.

If the 3rd piston cylinder in the second mode of execution of the present invention is removed, and correspondingly cancel the 6th radial direction oil 52b and the second interior control oil pipe 41b of the first axle on the first axle 52 in the second mode of execution, the topology layout of all the other component and the second mode of execution of the present invention are just the same, then consist of the 4th kind of mode of execution of the present invention: namely speed regulating mechanism, arrestment mechanism only have respectively the sticking transmission device of brake type liquid of a piston cylinder.

Such as Fig. 2, shown in Figure 10, above of the present invention second, third, the lubricating oil path of the 4th kind of mode of execution is: lubricant oil flows to from the radial direction oil 45a on the brake axle transparent cover 45, enter the 3rd axial oil duct 1b of brake axle 1 via the 4th radial direction oil 1a of brake axle 1, then, part lubricant oil enters the second lubricant oil oil pocket 43 via the 5th radial direction oil 1d on the brake axle 1, and another part lubricant oil directly enters the first lubricant oil oil pocket 39 via the 3rd axial oil duct 1b.Because the first tooth cover 31, the second tooth cover 7 can rotate with brake axle 1 high speed constant, thereby drive the first lubricant oil oil pocket 39, the second lubricant oil oil pocket 43 High Rotation Speeds, two lubricant oil oil pockets will produce respectively a constant centrifugal force thus, under the effect of this centrifugal force, lubricant oil is respectively through the first tooth cover 31, uniform small pores on the second tooth cover 7 enters active friction plate 25 equably, driven friction 24 and movable friction plate 8, between the static friction sheet 10, uniform oil film can be formed thus, the speed governing of the sticking transmission device of brake type liquid of the present invention can be greatly improved, braking ability.
