Description

Heavy-duty transfer case cooling system

Technical Field

The utility model relates to a vehicle chassis, in particular to heavy load transfer case cooling system.

Background

In a general heavy vehicle, the heat generated by the operation of the transfer case is mainly diffused through the shell in a heat radiation mode, and therefore the heat balance requirement can be met. However, for some special heavy vehicles, the heat dissipation condition is poor, the heat load of the power transmission system is large, the heat dissipation of the vehicle is difficult to meet the requirement in the continuous high-speed driving process, and the reliability of the transfer case and the dynamic property of the whole vehicle are directly influenced. Therefore, it is necessary to perform forced cooling of the actuator in a manner.

SUMMERY OF THE UTILITY MODEL

Therefore, the utility model provides a cooling system of a heavy-duty transfer case, which comprises an engine oil cooler, a transfer case and an engine cooling module, and is characterized in that,

the engine oil cooler comprises a water cooling pipeline and an oil pipeline, wherein the water cooling pipeline and the oil pipeline form a cooling structure so that the water cooling pipeline cools the oil pipeline;

and the water inlet and the water outlet of the water cooling pipeline are respectively connected with the engine cooling module to form a water cooling circulating system, and the oil inlet and the oil outlet of the oil pipeline are respectively connected with the gear oil outlet pipe and the gear oil return pipe of the transfer case to form an oil loop.

The utility model discloses an increase the oil cooler to in the engine water circulative cooling system, this oil cooler is connected with the transfer case again, carries out forced cooling to transfer case gear oil, therefore transfer case operating temperature can remain throughout at reasonable within range.

Detailed Description

The following is a further detailed description with reference to the accompanying drawings.

As shown in fig. 1-3, the utility model provides a heavy load transfer case cooling system, including oil cooler 2, transfer case 1 and engine cooling module 3, oil cooler 2 includes water-cooling pipeline and oil pipe way, and wherein water-cooling pipeline and oil pipe way form cooling structure so that water-cooling pipeline cools off oil pipe way; the water inlet and the water outlet of the water cooling pipeline are respectively connected with an engine cooling module through a water pipe a 6 and a water pipe b 7 to form a water cooling circulation system, the oil inlet and the oil outlet of the oil pipeline are respectively connected with a gear oil outlet pipe 4 and a gear oil return pipe 5 of the transfer case through an oil pipe 9 and an oil pipe 8 to form an oil loop, and therefore gear oil of the transfer case 1 can circulate in the oil loop and be cooled.

The utility model discloses in, the transfer case moves external machine oil cooler and reduces the gear oil temperature. The engine oil cooler is connected with the engine cooling module through external water pipes at two ends of the engine oil cooler respectively to form cooling water circulation; and then the transfer case is connected with the oil cooler through a transfer case oil inlet and outlet pipe. The oil inlet and outlet pipe is connected with the transfer case and the engine oil cooler through the adapter. The transfer case gear oil is forcibly cooled through cooling water circulation so as to meet the driving requirement.

Finally, it should be noted that: the above embodiment only illustrates one technical solution of the present disclosure, and although the present disclosure is described in detail by the accompanying drawings and the like, it should be understood by those of ordinary skill in the art that: modifications of some embodiments or equivalents of some of the technical features of the present disclosure may be made without departing from the design concept of the present disclosure, and similar solutions may still fall within the scope of the present disclosure.
