摘要： A multiple-transmission-ratio transmission arrangement includes at least first and second transmission-ratio-establishing units, for example brake bands and/or clutches, having hydraulically activated and unactivated states and operative in the hydraulically activated state for establishing respective first and second transmission ratios. An arrangement for changing the transmission ratio of the transmission arrangement comprises, in combination, a source of hydraulic activating fluid and conduits connected to the source and to the hydraulically activatable transmission-ratio-establishing units. Electrically controllable valves in the conduits are operative for alternately permitting and preventing the supply of hydraulic activating fluid to the transmission-ratio-establishing units. An electrical transmission-ratio-selecting arrangement is connected to the valves and is operative for charging the transmission ratio of the transmission arrangement by causing the valves to effect a change of state of one of the units and an opposite change of state of the other of the units. Included is an electronic timing arrangement operative during a change of transmission ratio for delaying the change of state of one of the units until after the change of state of the other of said units has been effected.

摘要： A device for controlling a motor vehicle clutch is disclosed. A hydraulic control system coupled to the disengagement lever of a clutch selectively engages and disengages the clutch responsive to a control signal. The control signal is generated by a control circuit which receives a first signal representative of the speed of the vehicle and a second signal representative of the rotary speed of the engine. The control circuit varies the control signal during each engagement of the clutch as a function of two components: a first component which initially varies as a substantially linear function of the speed of the vehicle and thereafter varies as a positive exponential function of the speed of the vehicle; and a second component which varies as a substantially linear function of the speed of the engine. Both components vary in a direction which drives the clutch further into engagement for increasing vehicle and engine speed.

摘要： An electromagnet and plunger assembly including a ring-shaped solenoid coil having a fixed pole component which extends from the one end into the interior of the solenoid coil. Movable in the axial direction, the plunger extends from the other end into the interior of the solenoid coil. A control device serving the adjustment of the armature pull comprises a sensor element measuring the magnetic induction. The pole component is subdivided in two pole parts which are coaxially nested and between which an annular gap is formed. The annular gap is sealed with a magnetically nonconductive material on its end facing toward the plunger. The sensor element is located in the annular gap in the interior of the solenoid coil.

摘要： The transmission arrangement includes first and second hydraulically activatable units. When the first and second units are activated and unactivated, respectively, the arrangement exhibits a first transmission ratio. When the first and second units are unactivated and activated, respectively, the arrangement exhibits a second transmission ratio. Electrically controllable first and second valves each connect an associated unit to a source of hydraulic fluid. A transmission-ratio changeover is effected by causing the valves to undergo opposite changes of energization state. Each valve has its own time-delay stage. Upon receipt of a signal commanding a transmission-ratio changeover, each time-delay stage delays the initiation of the change of energization state of the associated valve by a respective time-delay interval. During a changeover from the first to the second transmission ratio, the initiation of the change of energization state of the first valve can be made to either lead or lag that of the second valve, simply by making the first time-delay interval either shorter or longer than the second time-delay interval.

摘要翻译： 传动装置包括第一和第二液压可活动单元。 当第一和第二单元分别被激活和未激活时，该装置呈现第一传动比。 当第一和第二单元分别未激活和激活时，该布置呈现第二传动比。 电气可控的第一和第二阀每个将相关联的单元连接到液压流体源。 通过使阀门经受相反的通电状态的变化来实现变速比切换。 每个阀门都有自己的延时阶段。 在接收到指示传输比转换的信号时，每个延时级延迟相关阀的通电状态的改变的启动相应的延时间隔。 在从第一变速比到第二变速比的转换期间，可以简单地通过使第一时间间隔更短或者第一时间延迟间隔来缩短第一阀的通电状态的改变，使得第二阀的通电状态的开始或者延迟， 比第二个延时间隔长。
