Fig. 1 is the cross-sectional schematic of rigid dead axle described in the present embodiment, as shown in FIG., the rigid dead axle of the band oil-immersed multi-disk brake in the present embodiment comprises: end cover 1, jam nut 2, wheel hub 3, limiting stopper 4, drg protecgulum 5, brake casing 6, drg bonnet 7, spindle nose 8, end pellet 9, mount pad 10, girder 11, oiling vent 12, service brake hydraulic fluid port 13, lubricating oil inlet 14, inner support bearing 15, outer support bearing 16, end cap bolt of rear end plate 17, inspection door 18, reinforced seal 19, static friction sheet 20, movable friction plate 21, service brake piston 22, braking during standstill piston 23, braking during standstill spring 24, oil suction 25, parking release hydraulic fluid port 26, drg hold-down bolt 27, seal ring 28, disc spring 29, O-ring seals 30 and stop washer 31.Its medial end portions pellet 9 is welded on the two ends of girder 11, and mount pad 10 is welded on the upper and lower of girder 11.End pellet 9 weld together at spindle nose 8 and two ends, drg protecgulum 5, brake casing 6 and drg bonnet 7 and spindle nose 8, again by hold-down bolt 27, closely link together by whole oil-immersed multi-disk brake.Movable friction plate 21 and the spline fitted on wheel hub 3 of oil-immersed multi-disk brake inside, static friction sheet 20 coordinates with the female splines of brake casing 6, disc spring 29 is provided with between movable friction plate 21 and static friction sheet 20, wheel hub 3 is also provided with the oilhole be communicated with friction lining gap, in order to be communicated with friction lining gap and wheel hub 3 inner chamber.Drg bonnet 7 has oiling vent 12 and oil suction 25, and sealed by seal ring 28 between brake casing 6 and spindle nose 8.Brake casing 6 has service brake hydraulic fluid port 13, lubricating oil inlet 14 and parking release hydraulic fluid port 26, and also sealed by seal ring 28 between drg bonnet 7 and drg protecgulum 5.In drg outside in, successively static friction sheet 20, disc spring 29, movable friction plate 21, service brake piston 22, braking during standstill piston 23 and braking during standstill spring 24 are installed.Reinforced seal 19 and O-ring seals 30 are arranged on limiting stopper 4, are then connected with drg protecgulum 5 by bolt.Be connected by inner support bearing 15 and outer support bearing 16 between wheel hub 3 with spindle nose 8, this inner support bearing 15 and outer support bearing 16 are the tapered roller bearings arranged in pairs, and the gap of bearing is regulated by jam nut 2.Loosen in order to avoid working process jam nut 2 produces, it is locking that the every side of rigid bridge all adopts locking nut 2 to carry out machinery, while between two jam nuts 2, be designed with stop washer 31, prevent nut loosening further.End cover 1 is arranged on the outside of wheel hub 3 by end cap bolt of rear end plate 17, and Center has inspection door 18, utilizes O-ring seals and sealant to realize the sealing with wheel hub 3 inner chamber.
As shown in Figure 2, oil-immersed multi-disk brake circumference always has 5 interfaces, is service brake hydraulic fluid port 13, parking release hydraulic fluid port 26, lubricating oil inlet 14, oil suction 25 and oiling vent 12 respectively.
Before concrete installation, spindle nose 8, end pellet 9, mount pad 10 and girder 11 first need be welded into entirety, then successively drg bonnet 7, braking during standstill piston 23, brake casing 6, braking during standstill spring 24, service brake piston 22 are installed, next successively static friction sheet 20, movable friction plate 21 and disc spring 29 are installed again, finally drg protecgulum 5 is installed, and by bolt 27, drg protecgulum 5, brake casing 6, drg bonnet 7 and spindle nose 8 pre-installation are put in place, and adjust the angle of movable friction plate, be convenient to coordinate with wheel hub 3.
Before installation wheel hub 3, need first O-ring seals 30, limiting stopper 4 and reinforced seal 19 to be pre-installed on wheel hub 3, the inner ring of inner support bearing 15 is pre-installed on spindle nose 8, the outer ring of inner support bearing 15 and the outer ring of outer support bearing 16 are pre-installed on wheel hub 3, and then wheel hub 3 is inserted in drg, until with movable friction plate 21 groups of no-floats after, reinstall the inner ring of outer support bearing 16.Inner support bearing 15 and outer support bearing 16 are tapered roller bearing, need adjust the endplay of inside and outside backup bearing with jam nut 2.After adjustment, need to be carried out machinery by a jam nut 2 more locking, between two jam nuts 2, also need installation stop washer 31.
After wheel hub 3 installs, bolt is utilized limiting stopper 4 and drg protecgulum 5 to be linked together.Finally, by end cap bolt of rear end plate 17, end cover 1 is connected with wheel hub 3, and checks that highly whether enough liquid level supplement by the aperture of sight 18 at end cap central place.
Rigid dead axle with oil-immersed multi-disk brake before use, need be first connected with vehicle frame by mount pad 10, then service brake hydraulic fluid port 13, parking release hydraulic fluid port 26, lubricating oil inlet 14, oil suction 25 and the vent 12 that refuels is connected, guarantee that in wheel hub 3 cavity, lubricating oil height is suitable, seals non-leakage everywhere.
The corresponding actions of concrete use procedure is as follows:
(1) remove braking during standstill: pressure oil enters the annular space between brake casing 6 and braking during standstill piston 23 from parking release hydraulic fluid port 26, compression braking during standstill spring 24, makes braking during standstill piston 23 lateral movement inward.Meanwhile, disc spring 29 discharges, and movable friction plate 21 is separated with static friction sheet 20, is extruded by service brake piston 22 toward inboard simultaneously, realizes parking release.In the normal driving process of vehicle, need the pressure remaining parking release hydraulic fluid port 26, to guarantee being totally released of parking, otherwise will the service life of brake bush group be reduced.
(2) driving process braking: pressure oil flows into the annular space between service brake piston 22 and brake casing 6 from service brake hydraulic fluid port 13, disc spring 29 is compressed by squeezing travelling brake piston 22, make to produce relative contact and friction between movable friction plate 21 with static friction sheet 20, realize the object of service brake.
(3) braking during standstill is started: the pressure reducing parking release hydraulic fluid port 26, braking during standstill spring 24 extrudes braking during standstill piston 23, compress disc spring 29 by service brake piston 22 again, make to produce between movable friction plate 21 with static friction sheet 20 strong relatively to contact and friction, and final geo-stationary.
In the whole working process of vehicle, no matter vehicle is in halted state or motoring condition, lubricating oil is all forced to flow into from lubricating oil inlet 14, flow out from oil suction 25, positive lubrication and cooling are carried out to the friction lining group in whole drg, again because be provided with the oilhole be communicated with friction lining gap on wheel hub 3, so the lubricating oil flowing through friction lining group can also flow into the inner chamber of wheel hub 3, pair of interior support bearing 15 and outer support bearing 16 lubricate, and are flushed in oil-tank filtering device by the particulate matter in drg.If the working load of vehicle is little or flush loop fault, also lubricating oil inlet 14 and oil suction 25 can be closed, now will lose flushing refrigerating function, but not affect the normal use in the short time.
Except above-mentioned rigid dead axle, the present invention also provides a kind of vehicle being provided with above-mentioned rigid dead axle, and the structural reference prior art of other each several part of this vehicle, repeats no more herein.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
