Abstract
The utility model provides an oil lubrication drum type trailer bridge comprising a bridge pipe, a wheel hub and an oil seal. The wheel hub is rotatably mounted on the shaft head of the bridge pipe; the oil seal is arranged at a second side of the wheel hub; a wheel hub cover is mounted at a first side of the wheel hub; an oil injection hole is formed on the wheel hub cover; a plug is detachably sealed and covered in the oil injection hole; an oil stopping cover is mounted at the second side of the wheel hub; the oil stopping cover and the wheel hub cover are respectively located at the both sides of the oil seal; a sealing gasket is arranged between the wheel hub and the oil stopping cover; and further an oil leakage hole is formed on the wheel hub. According to the oil lubrication drum type trailer bridge provided by the utility model, the oil injection hole is arranged on the wheel hub cover, so that lubrication oil can be conveniently injected without dismounting any component, and the oil lubrication drum type trailer bridge is very convenient to maintain.
Description
Technical field
The utility model relates to a kind of auto trailer bridge, relates in particular to a kind of oil lubrication drum-type trailer axle.
Background technology
Along with the continuous improvement of highway in China condition, trailer is more widely used in engineering transportation and logistics transportation, and its load-carrying capacity depends primarily on the use of vehicle bridge.Present heavy Ka Qianyincheguacheqiao mainly uses 13 tonnes of grease lubrication trailer axles; Its bearing capacity directly restricts the car load load carrying ability; And grease lubrication is adopted on the wheel limit, and lubricating power is not high, the wheel limit life-span is short, just can carry out the interpolation of fat after need removing a lot of parts during maintenance.
The utility model content
To the defective of the grease lubrication of auto trailer bridge in the prior art, the utility model proposes a kind of oil lubrication drum-type trailer axle.
The oil lubrication drum-type trailer axle of the utility model comprises: bridge tube, wheel hub, oil sealing, wheel hub are rotatably installed on the spindle nose of bridge tube, and oil sealing is arranged on second side of wheel hub; First side of wheel hub is equipped with wheel hub cover, is formed with oil hole on the said wheel hub cover, in the oil hole removably capping obstruction is arranged; Second side of wheel hub is equipped with oil blocking cover, and oil blocking cover and wheel hub cover lay respectively at the oil sealed both sides, is provided with gasket seal between wheel hub and the oil blocking cover; Further be formed with the draining hole on the wheel hub.
Preferably, further be formed with relief port on the wheel hub cover.
Preferably, cross section, bridge tube stage casing is square, and sectional dimension is 150mm * 150mm, and wall thickness is 16mm.
Because the trailer axle of the utility model is provided with oil hole on wheel hub cover, can annotate to lubricating oil easily, need not remove any parts, safeguard very convenient.
Description of drawings
From purport and the preferred embodiment of use and the following description of accompanying drawing to explanation the utility model, above and other purpose, characteristics and the advantage of the utility model will be conspicuous, in the accompanying drawings:
Fig. 1 is the front view of the oil lubrication drum-type trailer axle of the utility model;
Fig. 2 is the section drawing in bridge tube stage casing of the oil lubrication drum-type trailer axle of the utility model;
Fig. 3 is the partial enlarged drawing of an end of the oil lubrication drum-type trailer axle of the utility model.
The specific embodiment
Below, 1-3 is elaborated to the utility model in conjunction with Figure of description.
Among this paper, oil lubrication drum-type trailer axle also can be described as oil lubrication drum brake trailer axle.
A kind of oil lubrication drum-type trailer axle, this trailer axle bridge tube 11 is the overall thermal extrusion forming, the bridge tube wall thickness increases 2mm with respect to 13 tonnes of trailer axle bridge tube wall thickness, thereby improves whole bridge bearing ability; Be welded with fixed bearing 1, powerful support 12, back-plate 10 on the bridge tube; The bridge tube both sides are brake wheels 8, and brake shoe assembly 3, brake camshaft 2, wheel hub 6, gasket seal 5, oil blocking cover 4, oil sealing 9, wheel hub cover 7 are arranged in the brake wheel 8; Wheel hub 6 and oil blocking cover 4 are through bolted connection, and the lubricating oil that oil blocking cover 4 reclaims is discharged through the draining hole 14 that forms on the wheel hub, and wheel hub cover 7 and wheel hub 6 have oil hole 13 and relief port through being threaded on the wheel hub cover 7; Realize oil lubrication through above connection, thereby make wheel limit lubricating power improve, each parts improves the maintenance simple and convenient service life.
The oil lubrication drum-type trailer axle of the utility model, bearing capacity is 11t～16t, is preferably 16t.
The oil lubrication drum-type trailer axle wheelspan of the utility model is 1800～1860mm, and the air chamber span is 355mm; Preferably, wheelspan is 1858mm.
In the oil lubrication drum-type trailer axle of the utility model, bridge tube is the overall thermal extrusion forming, and cross section, bridge tube stage casing is square, and sectional dimension is: 150mm * 150mm, wall thickness are 16mm; Composite bending modulus is big, good rigidly, load-carrying capacity are strong.The brake wheel internal diameter is φ 415mm～φ 425mm, and external diameter is φ 470mm～φ 480mm, and preferably, the brake wheel internal diameter is φ 419mm, and external diameter is φ 475mm.
Wheel hub cover the inner is an outside thread, and the screw thread specification is 6.25 " 8UN-1A; The wheel hub outer end is a negative thread, and the screw thread specification is 6.25 " 8UNC-2B, wheel hub cover and wheel hub are through being threaded; Inner gasket seal and the oil blocking cover of increasing of wheel hub, three parts pass through bolted connection; Oil blocking cover and wheel hub cover lay respectively at the oil sealed both sides.Realize wheel limit oil lubrication through above design, thereby improve wheel limit lubricating power and service life.
Although illustrated and described the preferred embodiments of the present invention, it is contemplated that, those skilled in the art can be in the spirit of the utility model and scope design to the various modifications of the utility model.
