Description

Semi-fluid attitude synthetic fat is filled the temperature indicator (TI) of axle
Present invention relates in general to a kind of novel temperature indicator (TI),,, when reaching unsafe temperature, provide the vision indication to the operator as the axle of trailer at the axle of the vehicle of the semi-fluid attitude synthetic fat of packing lubrication wheel bearing.Specifically, a form of the present invention relates to a kind of novel temperature indicator (TI), and it can be retrofitted in the existing axle for vehicle and not need to change the structure of axle.
Present trailer wheel hub/bearing arrangement has turned to and has used semi-fluid attitude synthetic fat lubricant, to be substituted in the bearing of the lubricated wheel of once widely used transmission oil in prior art trailer wheel hub/bearing.The synthetic fat of semi-fluid attitude has more advantage, because to take turns sealing less sensitive to incomplete, and thereby the not easy oil leakage of wheel wheel hub of filling than machine oil.
When the wheel wheel hub leakage of oil that machine oil is filled, machine oil diffusion or splash are full of all things in this district around axle.If seal failure makes machine oil on brake block and the brake drum cover, this can cause catching fire owing to the brake block and the brake drum of heating.
When semi-fluid attitude synthetic fat was filled the leakage of oil of arbor wheel hub, because semi-fluid attitude synthetic fat is more more solid-state than machine oil, semi-fluid attitude synthetic fat is diffusion or splash around axle unlike machine oil.Semi-fluid attitude synthetic fat is just extruded through sealing, or lose neatly, otherwise remain on direct zone around, thereby prevent to catch fire.
The advantage that adopts machine oil to fill the arbor wheel hub is that such wheel hub is easy to monitor with the window in the wheel hub with interstitial wire.If the user finds oil low (for example being lower than oil-filled line), reach oil-filled line as long as draw plug oil on the wheel hub cover will add to pasta.
Yet when filling the wheel hub that semi-fluid attitude synthetic fat fills, semi-fluid attitude synthetic fat does not flow through bearing, but tends to rest in the fat chamber in the wheel hub, even if to stop also be like this to wheel.Because use semi-fluid attitude synthetic fat, this especially occurs in arctic weather.At low temperatures, the same with fat, the viscosity of semi-fluid attitude synthetic fat increases, but at high temperature, semi-fluid attitude synthetic fat begins more mobile as thicking liquid.
Because this character of semi-fluid attitude synthetic fat has adopted the wheel hub cover that does not have window, thinks the wheel hub oil starvation to prevent the driver by mistake because of can not show oil level at window.Because the window with machine oil is inoperative when filling wheel hub with semi-fluid attitude synthetic fat, generally adopt simple metal or solid plastic lid.Consequent problem is that the driver can not monitor that axle is to judge whether to exist enough lubricated amounts.As everyone knows, if the bearing length time of wheel does not have sufficient working lubricant, bearing is heating significantly, and causes that wheel hub generates heat because bearing is pressed in wheel/wheel hub.If this situation is not always for finding that this can cause serious bearing fault.
The present invention proposes a kind of novel temperature indicator (TI), is filling the axle of semi-fluid attitude synthetic fat with the vehicle of lubricated its wheel bearing, and the indication of vision is provided for the operator when for example trailer axle has reached unsafe temperature.A kind of form of temperature indicator (TI) of the present invention can be retrofitted in the existing trailer easily, and needn't transform this trailer.Read appended explanation in conjunction with the research accompanying drawing and can understand other characteristics of the present invention and advantage.
