Inner tooth shell 2, detent housing 13 and outer end cap 17 are connected by outer-hexagonal bolt 19 and spring washer 20 and are fixed as one, outer end cap 17 with
O 18 it is provided with between detent housing 13.
Play the stator 7 of clutch action, moving plate 8 is equipped with multi-disc, stator 7 and moving plate 8 is interlaced is arranged in inner tooth shell 2
Inner side；Wherein being provided with braking backing plate 3 between inner tooth shell 2 inner surface and stator 7 and moving plate 8, stator 7 inner ring is fixed with wheel hub 1
Connecting, moving plate 8 outer ring is fixing with inner tooth shell 2 to be connected.Inner tooth shell 2 outer cylinder surface has and is communicated to inside inner tooth shell 2
Stator 7 and the installing hole of moving plate 8, installing hole is provided with two, the most altogether；Be provided with in inner tooth shell 2 installing hole oil stifled 5 with
And combination mat 6, blocking up 5 by oil can be to filling gear oil between stator 7 and moving plate 8.During use, fill tooth at brake inside
Wheel oil is to specifying liter number, and gear oil is to lower the temperature to brake(-holder) block group (stator 7 and moving plate 8), washes away brake(-holder) block group (stator 7 and moving plate
8) abrasive particle between, and anti-riot.Have the passage being communicated to inner tooth shell 2 installing hole in inner tooth shell 2 left side, passage sets
Putting one, be positioned at topmost, connect with the top installing hole, load breather plug 4 in passage, breather plug 4 is positioned at and blocks up 5 than oil
Closer to stator 7 and the position of moving plate 8, breather plug 4 maintains inside and outside air pressure balance when internal gas expanded by heating.
Service brake piston 12 is internal can be arranged on detent housing 13 along wheel hub 1 mode in axial sliding；Service brake
Piston 12 right-hand member has a seam coordinated with detent housing 13 circumference formula half the circumference of the sleeve where it joins the shoulder, so, in driving brake piston 12 and system
A service brake oil pocket is formed, detent housing 13 and the service brake piston 12 of service brake oil pocket both sides between dynamic housing 13
Between a Y-shaped ring 11 is respectively installed；Detent housing 13 has the A hydraulic fluid port 21 being communicated to service brake oil pocket；By by A
Hydraulic fluid port 21 injects hydraulic oil to service brake oil pocket, and service brake piston 12 can be promoted to move to left.Service brake piston 12 left end
Face is relative with stator 7 and moving plate 8, is used for compressing stator 7 and moving plate 8；It addition, in driving brake piston 12 left side and inner tooth shell
Back-moving spring 10 is set between 2；Service brake piston 12 left side has multiple spring mounting hole, and spring mounting hole is around driving system
Dynamic piston 12 axle center is uniformly distributed；A described back-moving spring 10 it is mounted in each spring mounting hole；At reset bullet
Spring 10 outer end is provided with spring backing plate 9；Spring backing plate 9 is in circular, and be arranged in inner tooth shell 2 one, spring backing plate 9 outer ring is only
On mouth；Back-moving spring 10 is used for promoting service brake piston 12 to carry out moving to right reset.
Parking braking piston 16 is internal can be arranged on detent housing 13 along wheel hub 1 mode in axial sliding；Parking braking
Piston 16 left end has a seam coordinated with detent housing 13 circumference formula half the circumference of the sleeve where it joins the shoulder, so, in parking braking piston 16 and system
A parking braking oil pocket is formed, detent housing 13 and the parking braking piston 16 of parking braking oil pocket both sides between dynamic housing 13
Between a Y-shaped ring 11 is respectively installed；Detent housing 13 has the B hydraulic fluid port 22 being communicated to parking braking oil pocket；By by B
Hydraulic fluid port 22 injects hydraulic oil to parking braking oil pocket, and parking braking piston 16 can be promoted to move to right.A hydraulic fluid port 21 and B hydraulic fluid port 2 is all
It is in tilted layout, is separated by 90 °.The little spring 14 of parking and big it is provided with between parking braking piston 16 right-hand member and outer end cap 17
Spring 15；Have multiple around the installation of the equally distributed spring in parking braking piston 16 axle center in parking braking piston 16 right side
Hole, these spring mounting holes are divided into three groups, often the distance in group spring mounting hole distance parking braking piston 16 axle center；Often
Little spring 14 and big spring 15 it is mounted on, it is ensured that parking braking piston 16 uniform force, little spring in one spring mounting hole
14 and big spring 15 outer end be against inside outer end cap 17.Shown in Fig. 2, large and small spring is circular cross-section cylindrical screw pressure
Contracting spring, for more common type, little spring is contained in big spring endoporus, i.e. inside and outside overlapping use；For preventing groups of springs and group
Between interfere, take group group to position.Little spring 14 and big spring 15 are used for promoting parking braking piston 16 to be moved to the left, parking system
Dynamic piston 16 left end and service brake piston 12 right-hand member joint, so, when parking braking piston 16 moves to left, can promote driving
Brake piston 12 moves to left together.
The present invention has four kinds of states: driving states, running brake state, parked state, emergency braking condition, below
It is described separately:
1) driving states: Fig. 1 shows that state is driving states, parking brake hydraulic fluid port B hydraulic fluid port feed liquor force feed, hydraulic pressure during this state
Power overcomes being moved to right by parking brake piston with joint efforts of groups of springs (little spring and big spring) to be pressed onto on outer end cap, parking brake
Producing gap between piston and running brake piston, running brake piston is mobile to the right under the effect of back-moving spring to be pasted
Tight parking brake piston, parking brake piston moves to right and loosens brake(-holder) block group (stator and moving plate), and wheel hub can be freely rotatable
Realize driving.
2) service brake state: on the basis of driving states, is passed through hydraulic oil to A hydraulic fluid port, and running brake piston is at oil
The spring force overcoming back-moving spring under the effect of pressure moves to the left, compresses brake(-holder) block group (stator and moving plate), brake(-holder) block group
(moving plate and stator) produces moment of friction under the effect of axial compressive force and limits the rotation of wheel hub, it is achieved braking.
3) parking braking state: parked state be vehicle stop on the basis of (now A hydraulic fluid port has oil pressure, it is also possible to
There is no oil pressure), cancel the oil pressure of B hydraulic fluid port, now parking braking piston is at groups of springs (little spring and big spring) spring-force driven dual
Under be moved to the left, or the spring force that push service brake piston overpowers back-moving spring is together moved to the left, service brake piston pressure
Tight brake(-holder) block group (stator and moving plate), brake(-holder) block group (moving plate and stator) produces static friction moment under the effect of axial compressive force
Prevent the rotation of wheel hub, it is achieved parking.
4) emergency braking condition: this is a kind of state of emergency, and normal condition prohibits the use of, and vehicle is at kinestate A hydraulic fluid port
Oil-feed pressure, B hydraulic fluid port cancels oil pressure, now service brake piston and parking brake piston mode and parking braking end-state one
Sample, but the axial force acted in brake(-holder) block group (stator and moving plate) is service brake and parking braking sum, produces this braking
The maximum brake torque that device can be generated by, the harm of this kind of braking is to have a strong impact on the service life of stator and moving plate.
