Abstract
The utility model discloses a water cooling transfer case, comprising a transfer case device and a transfer case cooler. A heat exchanger inside the transfer case is connected with an intake water pipe and an outtake water pipe of the transfer case; an intake water pipe of the transfer case cooler is connected and communicated with an outtake water pipe of a motor; an outtake water pipe of the transfer case cooler is connected and communicated with the intake water pipe of the transfer case while the outtake water pipe of the transfer case is connected and communicated with an intake water pipe of the motor. The technic proposal changes the intake oil pipe and the outtake oil pipe of the heat exchanger in the original transfer case into the intake water pipe and the outtake water pipe without changing structure of the original transfer case and perform cooling to the grease inside the transfer case by cooling water system of the motor and the transfer case cooler, leading to simple structure, easy installation inside vehicles and good cooling effect.
Description
Technical field
The utility model belongs to the cooling unit of vehicle component, is specifically related to a kind of water-cooled transfer case that utilizes engine cooling water to cool off.
Background technique
For the go-anywhere vehicle of four-wheel drive, the lubricated cooling of combined type is normally adopted in the cooling of transfer case lubricant oil.At the friction surface of high speed, heavy load, adopt forced draught lubricated, splash lubrication is adopted at other position.The generation of pressure oil is to be produced by the electronic or mechanical pump that is installed in transfer case or the automatic transmission case.The pressure oil that pump produces cools off by the transfer case cooler that in the heat exchanger of transfer case oil outlet tube in the transfer case oil is sent, then.Get back to heat exchanger in the transfer case along the transfer case oil inlet pipe again.,, the heat in the transfer case is taken away by the continuous circulation of pressure oil like this, thereby, the normal of transfer case lubricating oil temperature guaranteed.This by cooling means electronic or mechanical pump generation pressure oil, cost height, weak effect.Circulation by pressure oil comes cutting oil, and heat transfer efficiency is low, and cooling effect is poor, and the flow of the pressure oil that needs is big, and the volume of transfer case cooler is big, the cost height.
Summary of the invention
The purpose of this utility model is to provide a kind of water-cooled water-cooled transfer case that utilizes, to address the above problem.
The technical solution of the utility model is: the water-cooled transfer case, it comprises the transfer case device, transfer case intake pipe and transfer case outlet pipe that heat exchanger in the transfer case connects, it also comprises the transfer case cooler, the intake pipe of transfer case cooler is connected UNICOM with the outlet pipe of motor, the outlet pipe of transfer case cooler is connected UNICOM with the transfer case intake pipe, and the transfer case outlet pipe is connected UNICOM with the intake pipe of motor.
Described transfer case cooler is located at the place that facings the wind of vehicle, and particularly the transfer case cooler is connected on the radiator of motor.
This technological scheme does not change the structure of former transfer case, as long as will change inlet tube and outlet tube into into and out of oil pipe in the heat exchanger in the former transfer case, utilize the cooling water system and the transfer case cooler of motor, lubricant oil in the transfer case is cooled off, it is simple in structure, arrangement convenience in car, good cooling results.

Embodiment
Here the agent structure of transfer case does not show in the drawings, and only the heat exchanger that it is inner is illustrated out; Its structure and other structures are identical with existing structure, not tired stating.
Shown in Fig. 2,3, transfer case intake pipe 3 and transfer case outlet pipe 2 that the heat exchanger 1 in the transfer case connects, transfer case outlet pipe 2 is connected UNICOM with the intake pipe 6 of motor.Connect transfer case cooler 7 on the radiator 8 of motor, the intake pipe 4 of transfer case cooler 7 is connected UNICOM with the outlet pipe 5 of motor, and the outlet pipe 10 of transfer case cooler 7 is connected UNICOM with transfer case intake pipe 3.
As shown in Figure 3, transfer case cooler 7 comprises honeycomb duct 11, and honeycomb duct 11 outer surfaces are established radiating fin 12.
The shape of the heat exchanger 1 in the transfer case as shown in Figure 4.
Cooling principle is as shown in Figure 1: the heat of lubricant oil passes to cooling water by the heat exchanger in the transfer case in the transfer case, cooling water is under the effect of engine water pump, the outlet of the heat exchanger in the transfer case, through the transfer case outlet pipe to the engine water pump water intake, then, from the motor water outlet, introduce cooling water in the transfer case cooler that places the radiator front, cool off by fan 9,, get back in the transfer case along the transfer case intake pipe again from the transfer case cooler outlet.By the continuous circulation of cooling water, the heat of lubricant oil by cooling water, by fan and cooler, is dispersed in the atmosphere again.When the heat of taking away from lubricant oil equated with the heat that is dispersed into atmosphere, lubrication system just can reach thermal equilibrium.It is stable and normal that lubricating oil temperature could keep.
