This utility model executes the work general introduction of example
Running brake:
Running brake is " forward " structure, i.e. requires to use pressure to keep brake to engage.
Running brake is the effect utilizing hydraulic coupling, is slowed or stopped what driving wheel rotated.Foot brake pedal or operation retarder in central operation board in stepping on driver's cabin control bar, and when selecting switch to press to disk brake position retarder, " D " interface that hydraulic oil liquid will be transferred on rear disk brake, see Fig. 3 and Fig. 5.Enter the hydraulic oil of " D " interface, promote service brake piston 31 to be pressed against on the brake disc assembly being made up of pressing plate assembly 28, rotary friction pad 29 and slip liner 30.Friction plate is installed between slip liner 30, and is driven by drive hub 5 and dish driving wheel 27 by wheel hub.The spin down of driving wheel to be made or stopping, the thrust being applied on brake disc assembly, directly depend on the degree that foot brake valves is stepped on.
When release driving foot brake valves or retarder control bar, the pressure acting on service brake piston 31 i.e. eliminates, brake back-moving spring 36 presses closer the strength at retaining pin 35 head, makes retaining pin be withdrawn into by piston 31 in situ, thus relieves the pressuring action to brake disc assembly.
Parking brake:
This parking brake is " inversely " structure, i.e. requires to use pressure to keep it to disengage.
This brake is handled by the parking being arranged on right instrument board/brake hard control knob.It applies by spring force and discharges by hydraulic coupling.Pull-out control knob, hydraulic oil enters " F " interface, sees Fig. 3 and Fig. 5, and flow to the oil duct before parking braking piston 23 by the guide groove in brake disc shell 25.Now hydraulic oil will promote piston 23, overcome the tension force of first spring the 20, second spring 21, makes the pressure releases on pressing plate assembly 28, thus keep brake disc assembly to discharge.If pushing control knob, the oil pressure at " F " seam and compression parking braking piston 23 is i.e. released.The tension force of first spring the 20, second spring 21 recovers, and promotes piston 23, is pressed on keep plate assembly 28 and groups of friction plate 29 and slip liner 30.The rotary friction pad being now installed between slip liner is the most compacted, so that wheel is braked by moving to resting.
In a word, as long as " F " interface is without oil pressure, i.e. applies parking braking, otherwise parking braking will release.
