In fixing shape, friction brake includes braking clamp body 7, brake pad group 8 and brake disc 6, and brake disc 6 is solid with wheel hub 1
Fixed connection, brake pad group 8 is arranged on braking clamp body 7, and it cooperates to when car braking makes with brake disc 6
During braking clamp body 7 action, brake pad group 8 is pressed to brake disc 6 and produces friction brake force obstruction wheel hub 1 by braking clamp body 7
Rotating, Retarder has driving wheel 11, fixed wheel 10 and housing, is provided with slow working chamber, housing, electricity in housing
Casing body and braking clamp body 7 are fixedly connected sequentially, and fixed wheel 10 and driving wheel 11 are arranged in slow working chamber, and fixed
Wheel 10 is fixedly connected with the casing, and one end of the rotary shaft 9 of motor 21 is connected with driving wheel 11 by electromagnetic clutch 20,
The other end of the rotary shaft 9 of motor 21 is fixing with sun gear 4 to be connected, and electromagnetic clutch 20 is arranged on driving wheel 11 and electricity
Driving wheel 11 and the rotation of motor 21 is ordered about with the joint or separation that will pass through electromagnetic clutch 20 between the rotary shaft 9 of machine 21
The synchronous axial system of rotating shaft 9 or relatively rotate.When motor 21 obtains electric work, planet carrier 3 is fixed, and rotary shaft 9 is by too
Sun wheel 4 drive gear ring and the wheel 2 being fixed on wheel hub 1 rotate, and drive running car；During car braking, wheel 2
Rotate generating, recovery section braking energy by wheel hub 1, gear ring, sun gear 4 drive motor 21 rotary shaft 9, and produce
Raw certain braking moment.When needs Retarder works, electromagnetic clutch 20 adhesive, the rotary shaft of motor 21
9 drive driving wheel 11 to rotate, and produce retarder brake moment；When need not Retarder work, electromagnetic clutch 20
Separating, between the rotary shaft 9 of motor 21 and driving wheel 11, power transmission disconnects, and driving wheel 11 does not rotates, and can eliminate fluid power
The empty of retarder damages energy consumption.
As it is shown in figure 1, Retarder also has cooling heat radiation system, this cooling heat radiation system includes pump 12, inlet tube
Road, outlet conduit and radiator 16, the outlet of slow working chamber, outlet conduit, radiator 16, inlet pipeline ease up
The import of speed working chamber is sequentially connected the logical cooling medium closed circuit that formed, and the rotary shaft of pump 12 is fixing with driving wheel 11 even
Connect, and the pressure portion of pump 12 be connected in cooling medium closed circuit so as when electromagnetic clutch 20 to engage pump 12
Work drives the cooling medium flowing in cooling medium closed circuit.As it is shown in figure 1, connect on cooling medium closed circuit
There is compensation medium case 14.As it is shown in figure 1, cooling heat radiation system also includes temperature sensor 19 and cooling fan 15, temperature
Degree sensor 19 is arranged on the exit temperature for use in sensing cooling medium of slow working chamber, cooling fan 15

In and move in circulation passage by driving motor 13-2 band movable valve plug 13-3 thus change the circulation of circulation passage
Cross-sectional sizes.Control unit controls to drive motor 13-2 to rotate as required, will drive motor 13-2 by screw body
Rotary motion be changed into the rectilinear movement of spool 13-3, make the flow area of throttling control valve change.Import saves
Flow control valve 13 is connected with radiator 16 outlet, and cooling medium enters slow working chamber by it；Outlet throttling controls
Valve 18 is connected with radiator 16 entrance, and the fluid after energy-absorbing heats up is entered radiator 16 by it.If inlet throttle controls
Valve 13 flow area is big, outlet throttling control valve 18 flow area is little, then the liquid filled ratio of Retarder is high, brake force
Square is big；If inlet throttle control valve 13 flow area is little, outlet throttling control valve 18 flow area big, then hydrodynamic retarding
The liquid filled ratio of device is low, and braking moment is little.
As in figure 2 it is shown, electromagnetic clutch 20 includes magnetic conductive disk 20-6, magnetic powder 20-2, magnetic powder room and can external power supply
Excitation coil 20-3, magnetic conductive disk 20-6 are solidly set in the rotary shaft of motor 21, and excitation coil 20-3 is arranged on driving wheel 11

Part includes that slip ring, carbon brush 20-1 and relay, excitation coil, slip ring, carbon brush 20-1 and relay the most electrically connect
It is connected with external power source after connecing.Magnetizing coil 20-3 is installed in driving wheel housing 20-4, by carbon brush 20-1, slip ring,
Relay is connected with power supply, it is thus achieved that around produce magnetic field after power supply.Driving wheel 11 is revolved with motor by rolling bearing 20-5
Rotating shaft 9 is connected, and both can be freely rotatable when magnetizing coil 20-3 does not has electric current to pass through.Magnetic powder 20-2 is permissible
Magnetized 30～50 μm steel fine-particle powders, when magnetizing coil 20-3 does not has electric current to pass through, magnetic powder 20-2 is not subject to
The action of a magnetic field, is loosely distributed in magnetic powder indoor, and electromagnetic clutch 20 is released state, the now rotary shaft of motor 21
9 can be freely rotatable with driving wheel 11；When magnetizing coil 20-3 has electric current to pass through, magnetic powder 20-2 is fast under the action of a magnetic field
Rapid hardening is solid, " loose " state hold up in chain, forms " solid magnetic linkage " in magnetic field, and electromagnetic clutch 20 is for connecing
Conjunction state, connects as one the rotary shaft 9 of motor 21 with driving wheel 11.Magnetic conductive disk 20-6 is by spline and motor 21
Rotary shaft 9 be connected, along with the rotary shaft 9 of motor 21 rotates together.When Retarder does not works, electromagnetism from
Clutch 20 separates, and the rotary shaft 9 of motor 21 can not drive driving wheel 11 to rotate, and can eliminate the empty damage of Retarder
Energy consumption；During Retarder work, electromagnetic clutch 20 engages, and the rotary shaft 9 of motor 21 drives driving wheel 11 to rotate,
Realize vehicle retarder brake function.
