Detailed description of the invention
Below against accompanying drawing, by the description to embodiment, the detailed description of the invention to the present invention
It is described in further detail.
As depicted in figs. 1 and 2, this lock-up clutch, including planet carrier 7, clutch support
Dish 5, gear ring 1, splined hub 2, friction plate 3, steel disc 4, sealing ring, resetting piston 9,
Connector 12, piston 14, return spring 15.
It is bolted between planet carrier 7 and clutch support dish 5 and is fixed together, connect
Rear clutch support dish 5 and planet carrier 7 are shaftless to relative movement.Clutch support dish 5 is close
The external splines matched with steel disc 4 it is provided with at the cylindrical of steel disc 4, can be with steel disc 4 by flower
Key is attached.
Steel disc 4 is connected with clutch support dish 5 by spline and can be free to move axially, friction
Sheet 3 is connected with splined hub 2 by spline and can be free to move axially, friction plate 3 and steel disc 4
Interlaced arrangement is installed, compact conformation.
Splined hub 2 is attached by spline or gear teeth with gear ring 1, so that gear ring 1 and flower
Key hub 2 can mutually transmit moment of torsion and rotate with same rotating speed.Splined hub 2 is near friction plate 3
It is provided with the internal spline matched with friction plate 3 at endoporus, can be entered by spline with friction plate 3
Row connects.
Sealing ring includes sealing ring I 8, sealing ring II 10, sealing ring III 11, sealing ring IV 13,
Wherein, sealing ring I 8 and II 10 pairs of resetting piston two ends of sealing ring seal, sealing ring III
11 and IV 13 pairs of piston two ends of sealing ring seal.
Piston 14 is nested on planet carrier 7, and contacts with sealing ring III 11, sealing ring IV 13,
Forming hydraulic chamber, under hydraulic action, piston 14 can move along the axis of planet carrier 7,
The axial force that hydraulic action produces is applied on steel disc 4, pressing friction sheet 3 and steel disc 4,
Lock-up clutch is made to engage.This axial force is clutch support dish 5 and the assembly of planet carrier 7
Internal force, the spring bearing of planet carrier 5 will not be applied axial force, reliable operation, durable.
Return spring 15 is nested in the hole of planet carrier 7, lives with return in return spring 15 outer end
Plug 9 is connected, and wherein return spring 15 is cylindrically coiled spring.Resetting piston 9 nesting is expert at
In carrier 7, and contact with sealing ring I 8, sealing ring II 10, form hydro-cushion cavity,
When lock-up clutch rotates, the fluid of counter balance pocket produces centrifugal force, at dummy piston 14
Fluid is owing to rotating the centrifugal force produced.
Piston 14 and resetting piston 9 are attached by connector 12.This connector 12 is
Flexible member, the most afterburning laggard luggage is joined.There is hook-like configuration connector 12 both sides, with work
The hole of plug 14 and resetting piston 9 is mated, and assembly and disassembly is simple.
Lock-up clutch engages, and when i.e. piston 14 moves right, band follower link 12 moves right
Dynamic, meanwhile, connector 12 moves right and drives resetting piston 9 to move to right, and then compression return
Spring 15 makes it produce to be compressed axially.After extraneous hydraulic fluid pressure is removed, lock-up clutch
Separating, return spring 15 discharges the energy stored when it is compressed axially, and makes resetting piston 9 left
Moving, band follower link 12 is moved to the left, and drives piston 14 to move to left simultaneously, discharges friction plate 3
And the gap between steel disc 4, complete the action that lock-up clutch separates.
Return spring 15 is nested in the hole of planet carrier 7, and the installation length of return spring 15 is big
In the degree of depth in planet carrier 7 hole, the requirement of piston stroke when lock-up clutch engages can be met；Return
Position spring 15 is when original state, and return spring 15 protrudes the partial-length of planet carrier 7 and is equal to
Piston 14 stroke；This nested structure, the axial length portion of return spring 15 inoperative stroke,
Not increasing this lock-up clutch length, axial dimension is short, compact conformation, it is simple to arrange.
Above in conjunction with accompanying drawing, the present invention is exemplarily described, it is clear that the present invention implements
It is not subject to the restrictions described above, as long as have employed the design of the present invention and technical scheme carries out
The improvement of various unsubstantialities, or the most improved design by the present invention and technical scheme directly should
For other occasion, all within protection scope of the present invention.
