    • A torque converter automatic transmission of a motor vehicle is equipped with an overheat prevention system of the torque converter. The system comprises a first unit which detects the temperature of a hydraulic fluid in an oil pan of the transmission; a second unit which detects whether the engine is under high load condition or low load condition; a third unit which derives an overheat judging reference temperature in accordance with the detection of the second unit, the overheat judging reference temperature indicating a first reference temperature upon detection of the high load condition of the engine by the second unit and indicating a second reference temperature upon detection of the low load condition of the engine by the second unit, the first reference temperature being lower than the second reference temperature; and a fourth unit which carries out a given operation to lower the temperature of the torque converter when the temperature of the hydraulic fluid in the oil pan exceeds the overheat judging reference temperature.
    • 机动车辆的变矩器自动变速器配备有变矩器的过热预防系统。 该系统包括第一单元,其检测变速器的油盘中的液压流体的温度; 第二单元,其检测发动机是处于高负载状态还是低负载状态; 第三单元,其根据第二单元的检测导出过热判定基准温度,过热判断基准温度,在第二单元检测到发动机的高负载状态时表示第一基准温度,并指示第二基准温度 在第二单元检测到发动机的低负载状态时,第一参考温度低于第二参考温度; 以及第四单元,当油底壳中的液压油的温度超过过热判定基准温度时,执行给定的操作以降低变矩器的温度。

    • A structure of an automatic transmission includes first and second clutches which are arranged radially so that one is surrounded by the other. This arrangement can reduce the size of the automatic transmission. For example, the first clutch has a first clutch drum splined to an input shaft of the transmission, a first clutch hub, and a first clutch pack between the first clutch drum and hub. The second clutch has a second clutch drum received in, and splined to, the first clutch drum, a second clutch hub, and a second clutch pack therebetween. The second clutch pack is surrounded by the first clutch pack. The second clutch further includes a piston which encloses the first clutch drum and which has a pushing portion on one side of the second clutch pack and a pressure receiving portion on the opposite side.
    • 自动变速器的结构包括第一离合器和第二离合器,该第一和第二离合器径向设置成一个被另一个离合器包围。 这种布置可以减小自动变速箱的尺寸。 例如,第一离合器具有花键连接到变速器的输入轴的第一离合器鼓,第一离合器毂和第一离合器鼓和轮毂之间的第一离合器组件。 第二离合器具有容纳在第一离合器鼓中的第二离合器鼓,第二离合器鼓,第二离合器毂和第二离合器组之间。 第二离合器组件被第一离合器组件包围。 第二离合器还包括封闭第一离合器鼓的活塞,并且在第二离合器组件的一侧具有推压部分和在相对侧的压力接收部分。
