The work general introduction of the embodiment of the present invention
Service Brake:
Service Brake is " forward " structure, namely requires to use pressure to keep break to engage.
Service Brake is the effect utilizing hydraulic coupling, slows down or stops driving wheel rotating.When the foot brake pedal stepped in operator cabin or the retarder controlling rod operated on central console, and by retarder selector switch by during to disk type braker position, hydraulic oil liquid will be transferred to " D " interface on rear disk type braker, see Fig. 2.Enter the hydraulic oil of " D " interface, promote service brake piston 31 and be pressed against on the brake disc assembly that is 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.Make spin down or the stopping of driving wheel, be applied to the impacting force on brake disc assembly, directly depend on the degree that foot brake valves is stepped on.
When discharging driving foot brake valves or retarder controlling rod, namely the pressure acting on service brake piston 31 eliminated, break Returnning spring 36 presses closer the strength at retaining pin 35 head, makes retaining pin that piston 31 is withdrawn into original position, thus relieves the pressuring action to brake disc assembly.
Parking Brake:
This Parking Brake is " reverse " structure, namely requires to use pressure to keep it to throw off.
This break is handled by the parking be arranged on right instrument panel/emergency braking control knob.It applies by spring force and discharges by hydraulic coupling.Pull-out control knob, hydraulic oil enters " F " interface, see Fig. 2, and flows 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 the first spring 20, second spring 21, make the pressure releases on pressing plate assembly 28, thus keep brake disc assembly release.If push control knob, be namely released at the oil pressure of " F " jointing and compression parking braking piston 23.The tension force of the first spring 20, second spring 21 recovers, and promotes piston 23, is pressed on keep plate assembly 28 and friction plate in groups 29 and slip liner 30.Now be installed in rotary friction pad between slip liner and compacted, thus wheel is braked by moving to resting.
In a word, as long as " F " interface, without oil pressure, namely applies parking braking, otherwise parking braking will discharge.
Also comprise a kind of quarry tipper in embodiments of the invention, be provided with a kind of quarry tipper wet brake described above.Because above-mentioned a kind of quarry tipper wet brake has above-mentioned technique effect, therefore, the quarry tipper being provided with this kind of quarry tipper wet brake structure also should possess corresponding technique effect, and its specific implementation process is similar to the above embodiments, does not hereby repeat.
Be described in detail specific embodiments of the invention above, but it is just as example, the present invention is not restricted to specific embodiment described above.To those skilled in the art, any equivalent modifications that the present invention is carried out and substituting also all among category of the present invention.Therefore, equalization conversion done without departing from the spirit and scope of the invention and amendment, all should contain within the scope of the invention.
