Description
Technical field
The utility model relates to four-wheel driven car power train manufacturing technology field, relates to a kind of four-wheel driven car gearbox with cooling and forced lubrication in particular.
Background technique
Usually the 4 wheel driven automobile gearbox adopts the splash lubrication mode lubricated, and action effect is not fine, and some bearing may can not get sufficient lubrication and cause bearing to damage in early days when gearbox turn round.
Four-wheel driven car gearbox transmitting torque is bigger, and gearbox internal gear oil temperature is very high, very easily causes gear oil rotten, thereby causes dry friction such as gearbox internal gear, bearing, it is ablated damage.Can cause whole gearbox to damage when serious, cause unnecessary loss.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of four-wheel driven car gearbox with cooling and forced lubrication.
Technical solution of the present utility model be gearbox 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, 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.
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, another road is transported to clutch housing and transfer case junction by the lubricant pipe that is installed in gearbox inside, and then be divided into two-way: the oil duct of leading up on the housing is transported to case of transmission lubrication right bearing, and another road is transported to right bearing seat right bearing in the transfer case by the transfer case internal oil channel.Can carry out pressure lubrication to the bearing in gearbox and the transfer case like this.
In the above-mentioned transfer case, the position of laying bearing, oil sealing is provided with oilhole.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 gear oil in the transfer case in the oilhole.Gear oil in the gearbox and the gear oil in the transfer case are the gear oils of two kinds of different sizes.
Above-mentioned heat dissipating pipe is a U type pipe.This heat dissipating pipe good heat dissipation effect.
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.
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 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.
The utility model is opened oil leab owing to increasing in an oil pump, the housing in gearbox inside, heat dissipating pipe is set up in the outside, gearbox internal gear oil enters outside heat dissipating pipe through oil pump, and the oil leab that enters in the gear box casing through the cooled gear oil of heat dissipating pipe carries out pressure lubrication.Therefore both can reduce gearbox internal gear oil temperature, can improve the lubrication effect of bearing to the bearing pressure lubrication in the gear box casing again, prolong the working life of gearbox inner bearing, gear.
