    本实用新型安全自动循环换油结构，指一种换油回路精确、而且油压保持平衡不会有油液管路爆管危险的安全自动循环换油结构。由低压油缸及高压自动节流阀所组成，低压油缸中以活塞区分成上层新油区及底层旧油区，活塞端面呈Ｖ字状，缸顶设新油注入口及空气管，空气管串接空气切换开关、空气调压阀及气压表；新油区连结出新油管，而旧油区连结出旧油管，新、旧油管连接油路切换开关；切换开关以第一油管连分油阀，相接于高压自动节流阀及第二油管，第二油管串接油量计及滤油芯，第三油管串接油压表，高压自动节流阀串接第四油管连接三通，三通一端连接于补油桶，另一端连接油量计，该油量计与新油管则设另一三通连接。

    The utility model relates to a safe, automatic and cyclic oil-changing structure with precise oil-changing loop and stable oil pressure without risk of explosion of the oil pipeline. The device consists of a high-pressure automatic throttle valve and a low-pressure cylinder which is separated into an upper new oil area and a lower used oil area by a piston area with V-shaped surface; an inlet for new oil and an air pipe linking air switch, air regulating valve and barometer are provided on the top of the low-pressure cylinder. A new oil feeding pipe from the new oil field and an old oil feeding pipe from the used oil field are connected by an oil-loop switch which is connected to different pipes and valves: a first oil feeding pipe connects to an oil distribution valve; a second oil feeding pipe links an oil gauge and a filter element in series; a third oil feeding pipe connects to an oil pressure gauge; and a high-pressure automatic throttle valve links a fourth pipe and a tee joint in series, one end of which connects to a bucket of make-up oil and the other end of which connects to the oil gauge linking the new oil feeding pipe by another tee joint.
 
    本实用新型涉及的是一种汽车紧急制动助停装置。它由连接在车大梁上的主伸缩臂座，铰连于主伸缩臂座上的主伸缩臂、连接于主伸缩臂末端的助停摩擦板组成的助停拖板组件，由连接在车大梁上的副伸缩臂座、铰连于副伸缩臂座上的副伸缩臂、连接于副伸缩臂末端升降部件所组成控制助停拖板升降组合件，由安装于车架上的贮气罐、连通贮气罐与主、副伸缩臂压缩气腔的气管、控制气体通断的电磁阀组合而成气动操控件这三大部件组合而成。具有提高汽车紧急制动时的地面摩擦阻力，在同等条件下能缩短汽车的刹车距离，大大提升了行车的安全性的特点，且结构简单，操作方便，使用可靠。

    The utility model relates to an Emergency Braking Aid (EBA) on automotive. It comprises the following three main components: A braking assistance planker subassembly composed of a principal telescopic jib support connected on automotive frame, a principal telescopic jib pivoted with the principal telescopic jib support, and braking assistance friction plates connected with ends of the main telescopic jib; a groupware to control elevation of the braking assistance planker subassembly consisting of an auxiliary telescopic jib support connected with the automotive frame, an auxiliary telescopic pivoted with the auxiliary telescopic jib support and a suspension component connected with ends of the auxiliary telescopic jib; and a pneumatic control part composed of an air chamber positioned on chassis, an air pipe connecting the air chamber with the compression air cavity of the principal and the auxiliary telescopic jibs and an electromagnetic valve to control air flow. The utility model is characterized in enhancing ground friction resistance during emergency braking, shortening automotive braking distance in the equivalent conditions and greatly improving steering safety. Moreover, it has advantages of simple structure, easy operation and reliable utilization.
