Described emergency brake piston another side compresses described friction plate combination；
Whole brake inside power is transmitted by active spiral bevel gear, and described active spiral bevel gear is installed described by bearing
On piston cylinder seat, its other end is input flange；The centre of active spiral bevel gear is connected with a spacer shell by spline, described mistake
The internal spline friction plate crossing during set is combined with friction plate by spline connects；
The opposite side of described stopping brake piston opposed spring seats lid is provided with can be by stopping brake piston to spring flap
First oil pocket of side extruding；Described emergency brake piston is provided with piston cylinder seat can be by emergency brake piston to friction
Second oil pocket of piece combination extruding；Described first oil pocket and the second oil pocket are connected with external high pressure oil pipe by tubing interface.
Spring flap of the present invention is bolted on one end of described piston cylinder, described piston cylinder seat
It is bolted on the other end of piston cylinder；Described active spiral bevel gear passes through two taper roll bearings and installs described work
On plug cylinder seat, input flange is arranged on the described active spiral bevel gear other end by spline and locking nut.
It is fixed with laterally inserted piston cylinder by a nut on spring base lid of the present invention and be connected to parking system
Releasing braking bolt in piston.
Present invention is mainly applied to drive axle central transmission input, turn round because axle reduction increases, compare existing
There is a structure being applied to drive axle wheel edge, brake brake force needed for whole machine and oil pressure all has and to a certain degree reduces, compact structure, peace
Dress is convenient；It has rational in infrastructure, and dependability is good, integrates stopping brake and brake hard, can effectively improve down-hole
Mine vehicle security, braking is steadily reliable, the features such as occupying little space.
Brief description
Fig. 1 is one embodiment of the present of invention appearance schematic diagram；
Fig. 2 is the left view of Fig. 1；
Fig. 3 is the cross section structure diagram of the present invention.
Specific embodiment
Below in conjunction with accompanying drawing, the present invention will be described in detail: shown in Fig. 1-3, normally closed type of the present invention stops and makes
Dynamic device, it mainly combines 7, stopping brake piston 5, brake hard by spring flap 4, piston cylinder 6, piston cylinder seat 10, friction plate
Piston 8 and active spiral bevel gear 11 form piston cylinder 6 two ends fixed spring flap 4 He respectively it is characterised in that described
Piston cylinder seat 10, is mounted with stopping brake piston 5 and emergency brake piston 8 in piston cylinder, and stopping brake piston 5 and urgent
It is mounted with a friction plate combination 7 between brake piston 8；
Spring flap 4 and described stopping brake piston space are provided with multigroup compression cluster spring, and described compression combination bullet
Spring acting force of the spring in normal state makes described stopping brake piston top be pressed in described friction plate group to close, and wherein said rubs
The internal spline on external splines steel disc and described piston cylinder in pad combination connects；
Described emergency brake piston passes through bolt 14, resilient sleeve 13 and compression cluster spring 9 and is arranged on described piston cylinder
On seat 10, described emergency brake piston another side compresses described friction plate combination；
Described active spiral bevel gear 11 is installed on described piston cylinder seat 10 by bearing, and its other end is input flange 1；Main
The centre of dynamic spiral bevel gear 11 is connected with a spacer shell 15 by spline, during described spacer shell 15 is combined with friction plate by spline
Internal spline friction plate connect；
The opposite side of described stopping brake piston 5 opposed spring seats lid 4 is provided with can be by stopping brake piston to spring base
Cover the first oil pocket of 4 side extruding；Described emergency brake piston 8 be provided with piston cylinder seat can by emergency brake piston to
Second oil pocket of friction plate combination 7 extruding；Described first oil pocket and the second oil pocket pass through tubing interface with external high pressure oil pipe even
Connect.
Spring flap 4 of the present invention is fixed on one end of described piston cylinder 6 by bolt 3, described piston cylinder
Seat 10 is also by the other end being bolted to piston cylinder 6；Described active spiral bevel gear 11 passes through two taper roll bearings
18th, 12 install on described piston cylinder seat 10, input flange 1 passes through spline and locking nut 19 is arranged on described active spiral bevel gear
The other end.

Releasing braking bolt 16 beyond the Great Wall.
The present invention inputs original paper by described input flange external connection power, and concrete operating principle is: passes through when whole machine starts
Tubing interface, as shown in Figure 1；Hydraulic oil is injected the first oil pocket of sealing, now described stopping brake piston rubs away from described
Pad combine, release stopping brake, power via described active spiral bevel gear pass on the driven gear within drive axle from
And drive whole machine walking.The described compression spring being distributed in system oil-break on described spring base lid passes through described stopping brake
The described friction plate of piston compression combines thus producing braking function, and parking brake function comes into force automatically.In driving a vehicle, situation occurs
When needing brake hard, hydraulic oil is injected to the second oil pocket of sealing by tubing interface, oil pressure promotes described brake hard to live
The described friction plate combination of plug compression produces braking function, and oil pressure unloads rear described emergency brake piston in compression cluster spring 9
Effect is lower to be resetted, and brake force disappears.When whole machine break down need mobile when, now parking brake is in on-position, institute
State and releasing braking bolt 16 has been threaded connection on stopping brake piston, tighten the nut being distributed on described spring base lid
17, under threaded function, described stopping brake piston combines away from described friction plate, and brake force disappears.
