Abstract
The utility model discloses a lubrication mechanism in four wheel driving vehicles transmission system. The utility model has the technical proposal that an oil hole is positioned in a transfer case at the position where a bearing and an oil seal are arranged, therefore, the oil can more easily flow into the part that is needed to be lubricated, the lubrication effect is improved and the service life of the parts in the transfer case is prolonged.
Description
Technical field
The utility model relates to four-wheel driven car power train manufacturing technology field, relates to the lubricating structure in a kind of four-wheel driven car power train in particular.
Background technique
Usually the transfer case in the four-wheel driven car power train is lubricated to part in the transfer case by the splash lubrication mode, and some part lubricant oil is not easy to arrive, and lubrication effect is not very desirable.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of easier need lubricant housings that flows to of oil that allows, the lubricating structure in the four-wheel driven car power train of raising lubrication effect.
Technical solution of the present utility model is in transfer case, and the position of laying bearing, oil sealing is provided with oilhole.
Gearbox is inner increase in an oil pump, the gear box casing open oil leab, heat dissipating pipe is set up in the outside, the gear oil pump filler opening connects oil purifier, oil purifier places the gear oil of gearbox, and oil outlet connects heat dissipating pipe, and the interior oil leab of the return opening of heat dissipating pipe and gear box casing is connected.Can reduce gearbox internal gear oil temperature like this, again can be to the bearing pressure lubrication in the gear box casing,
Above-mentioned oil leab is divided into two-way: the oil duct of leading up on the housing is transported to case of transmission lubrication left bearing, lubricant pipe feed track clutch housing and the transfer case junction of another road by being installed in gearbox inside, and then be divided into two-way: lead up to oil duct feed track case of transmission lubrication right bearing on the housing, another road is by right bearing seat right bearing in the transfer case internal oil channel feed track transfer case.Can carry out pressure lubrication to the bearing in gearbox and the transfer case like this.The effect of oilhole is to allow the easier inflow of gear oil in the transfer case need the lubricant housings, is different with lubricant oil in the oil duct, is gearbox gear oil in the oil duct, is the hypoid oil in the transfer case in the oilhole.Can carry out pressure lubrication to the bearing in gearbox and the transfer case like this.
Above-mentioned heat dissipating pipe is a U type pipe.
Above-mentioned oil pump adopts cycloid rotor pump, is made up of the rotor of engagement in a pair.This interior engagement cycloid rotor pump is compared advantage with the gear pump of other form and is: compact structure, and size is little, and is in light weight, gear rotation is to identical, relative sliding velocity is little, and it is little to wear and tear, long service life, flow pulsation is little, stable drive, noise are allowed use high rotating speed (centrifugal force that high rotating speed is little can make fluid better pour the seal operation chamber) for a short time, can obtain higher volumetric efficiency, discharge capacity is big, and the oil suction condition is good.
The side of above-mentioned oil pump is provided with is convenient to be fixed on the fastening bolt hole of using in the gearbox.Be suitable for like this in gearbox, installing.
Some apertures have been opened on the above-mentioned lubricant pipe that is installed in gearbox inside.The high pressure oil that is come out by oil pump ejects to the gearbox internal gear lubricated by these apertures.
The utility model is because in transfer case, the position of laying bearing, oil sealing is provided with oilhole.Can allow easier the flowing to of oil need the lubricant housings, improve lubrication effect, prolong the working life of component in the transfer case.
