The invention discloses an oil temperature adjusting device for a vehicle power-assisted steering system and a control method. The steering oil heat exchanger is communicated with a power-assisted steering system through a steering oil pipe and comprises a heat exchange pipe, an oil inlet, an oil outlet and oil change-over valves, wherein the oil inlet and the oil outlet are formed in the two ends of the heat exchange pipe, and the oil change-over valves are arranged at the oil inlet and the oil outlet. The steering oil heat exchanger is communicated with a steering gear or a steering oil tank through a steering oil pipe and used for adjusting the temperature of steering oil entering the steering oil heat exchanger. When the steering oil temperature of a power assisting system is too low or too high, the steering oil temperature adjusting device can be used for adjusting the oil temperature of steering oil entering the steering oil heat exchanger; the operating temperature of the power-assisted steering system is quickly and basically the same as that of engine cooling liquid, steering oil with relatively stable temperature is provided for the power-assisted steering system, the applicable operating condition of the power-assisted steering system is enhanced, the service life of each part of the power-assisted steering system is prolonged, and the failure rate of the power-assisted steering system is reduced.

    本发明公开了一种用于车辆转向助力系统的油温调节装置及控制方法。它包括通过转向油管与转向助力系统连通的转向油热交换器,所述转向油热交换器包括热交换管、设于热交换管两端的进油口和出油口、设于进油口和出油口处的油液转换阀,所述转向油热交换器分别通过转向油管与转向器或转向油罐连通用于调节进入转向油热交换器内的转向油温度。本发明可在助力系统转向油温过低或过高时,用于调节进入转向油热交换器内的转向油油温;使转向助力系统的运行温度快速与发动机冷却液基本同温,为转向助力系统提供温度相对稳定的转向油,强化转向助力系统的适用运行工况,提高转向助力系统各零部件的的使用寿命,降低转向助力系统的故障率。
