Description

A kind of axle tag wheel hub of heavy truck trailer

Technical field

It the utility model is related to truck Trailer axle, more particularly to the wheel hub spindle nose of Trailer axle.

Background technology

The wheel hub spindle nose of existing truck Trailer axle domestic at present, lubricating system are oil lubrication, self-contained bearing Fit standard wheel rim, it is that the trailer of heavy truck is supporting for double-body bike bearing.Although this mode can be used in the supporting row of trailer Walk, but maintaining is wasted time and energy, and service life is short.

Utility model content

The purpose of this utility model, just it is to provide a kind of axle hub spindle nose of the heavy truck trailer of new structure, if Meter is reasonable, simple in construction, safe and convenient to use, can be increased the service life with non-maintaining maintenance, reduces cost, and supporting effect is good, Improve economic and social benefits.

Task of the present utility model is so completed：Design a kind of axle tag wheel hub of heavy truck trailer, spindle nose Hub inner lumen uses latus rectum bearing position, and the spindle nose of axle shaft is equipped with integrated bearing, and axis head nut is fastened on spindle nose end face, will Integrated bearing is fixed on the spindle nose of axle shaft, and the wheel rim seam of spindle nose wheel hub 2, can fit standard wheel rim using seam is thickeied With thickening wheel rim, spindle nose wheel hub outer end installation hub spindle head end cover, integrated bearing and axis head nut are encapsulated in interior.Integral type An oil sealing is respectively equiped with inside inside and outside two end faces of bearing, two oil sealings fill lubricating grease, in integrated bearing The corresponding cooperation in outer face of two groups of taper rollers.Thicken the aluminium alloy wheel rim that wheel rim is thickness 27mm.During practical application, according to Need to match standard rim or thicken wheel rim, the wheel rim for being sleeved on spindle nose wheel hub 2 is thickeied on seam.

Implemented according to such scheme and tested, it was demonstrated that it is of the present utility model rational in infrastructure, it is easy to install, it is supporting Effect is good, and sealing is tight, and lubrication is abundant, can increase the service life from maintaining, and cost is low, and effect is good, economic society effect It is beneficial notable, admirably achieve predetermined purpose.
