The invention provides an electric bypass valve, a radiator, a cooling system and a lubricating oil temperature control method, and the electric bypass valve comprises a valve seat which is installed on a radiator shell through threaded connection; the valve assembly is composed of a sliding valve rod, a spring, a valve and a guide piece. Wherein an internal thread is designed on the sliding valve rod and used for being connected with an external thread of the motor; the valve is matched with the sealing surface in the end cover of the radiator for sealing, and the sealing state is correspondingly a non-bypass state, that is, most lubricating oil flows through the core body of the radiator, and the lubricating oil in the non-sealing state is directly bypassed without passing through the core body of the radiator; spring force generated by compression of the spring can enable the valve to be matched with a sealing surface in the radiator more tightly, and bypass leakage is prevented; the guide piece provides movement guide for the valve, and clamping stagnation is prevented; the spring, the valve and the guide piece are mounted on the sliding valve rod through threads; the motor assembly is composed of a hybrid stepping motor and a sliding lead screw.
本申请提供了一种电动式旁通活门、散热器、冷却系统和滑油温度控制方法,所述电动式旁通活门包括:活门座,通过螺纹连接安装在散热器壳体上;活门组件,由滑动活门杆、弹簧、活门、导向件组成;其中,滑动活门杆设计有内螺纹,用于连接电机外螺纹;活门与散热器端盖内部密封面配合进行密封,密封状态对应的为非旁通状态,即滑油绝大部分流经散热器芯体,非密封状态滑油则不经过散热器芯体而直接旁通;弹簧受压缩产生的弹簧力能使活门与散热器内部密封面配合得更加紧密,防止旁通泄漏;导向件为活门提供运动导向,防止卡滞;弹簧、活门、导向件通过螺纹安装在滑动活门杆上;电机组件,由混合式步进电机和滑动丝杠两大部分组成。
