大马力重载全驱大件牵引车分动箱油冷器设计及应用

大件牵引车是用于运输不可拆解的重型大件货物的专用车辆。其动力系统通常具有较大的马力和较高的扭矩。主要的运输工作过程中车辆处于长时间的重载工作情况,所以车辆在对与整车的动力及传动系统、冷却系统等方面的要求较高。而分动箱作为传动系统的重要组成部件,分动箱的性能对整车有着较为直接的影响。大件牵引车由于低速重载情况下长时间的工作,分动箱内的齿轮油发热严重产生高温,直接影响齿轮的性能及车辆的安全,故针对分动箱油温较高的情况,设计一套油冷器用于冷却分动箱油温,从而从根本上解决了车辆长时间处于低速重载作业过程中,分动箱油温较高对分动箱性能及齿轮使用寿命的不利影响。提高整车的可靠性和寿命,从而提高车辆的性能质量。

Design and Application of Oil Cooler for Transfer Case of Heavy-duty Full-drive Tractor

The bulk tractor is a special vehicle for transporting the heavy bulk goods that cannot be disassembled. The power system usually has higher horsepower and higher torque. The main transport work in the process of the vehicle in a long period of heavy load work, so the vehicle and the whole vehicle in the power and transmission system, cooling system and other aspects of higher requirements. As an important part of the transmission system, the performance of the transmission box has a direct impact on the vehicle. Big tractor due to the long hours under the situation of low speed and heavy loading, transfer case the gear oil fever badly to produce high temperature, a direct impact on the performance of the gear and the safety of the vehicle, therefore, in the presence of transfer case oil temperature is higher, design a set of oil cooling is used to transfer case case oil temperature cooling, thus fundamentally solver the vehicle for a long time in the operation of low speed and heavy loading loading process, the transfer case oil temperature is higher on the transfer case performance and service life of gear. Improve the reliability and life of the vehicle, so as to improve the performance quality of the vehicle.
