本发明涉及具有电动润滑泵（M），用于车辆没有它们自己的电源，例如拖车集中润滑系统，商用车辆的半拖车OD一样。具有用于作为所述车辆的运行时间的函数操作所述润滑剂泵的电定时控制器（Z）。 根据本发明，时序控制器的电源和用于刹车灯的电源线的润滑油泵驱动电动机（M）中进行。 时间控制装置具有传感器（S），其检测车辆或车辆的部件和运动期间的运动以产生用于第二计时器（T2）的信号。 第二定时器增加了由传感器提供的各信号的时间长度，该时间段的总和与预定的暂停时间（t2）进行比较，并且，在超过预定的暂停时间到第三计时器（T3），其由此使能和信号 selbt一个用于切换所述润滑泵的驱动电动机（M）使能信号传送下一个制动操作; 第三定时信号求和连续制动操作的持续时间，其中，所述润滑剂泵的驱动马达被接通时，在到达预先设定的工作时间的信号至所述第二计时器（T2）与预定的工作时间的时间段（T3）和，的总和进行比较，从而 由第二计时器发出的信号使能信号，从而也对的润滑剂泵消失驱动马达切换使能信号。

The invention relates to a central lubrication system with electric motor lubrication pump (M) for vehicles without their own power source, such as trailers, trailers of commercial vehicles od. Like. With an electric timing device (Z) for the lubricating pump actuating function of the operating time of the vehicle. According to the invention, the power supply of the timing controller and the drive motor (M) for the lubricating pump of the feed lines of the brake lights is carried out. Said timing control means has a sensor (S), which detects movements of the vehicle or of vehicle parts and during the movement generates a signal to a second timing element (T2). The second timing element adds the time length of each supplied from the sensor signals, the sum of the time duration compared with a predetermined pause time (t2) and are at the predetermined pause time is exceeded, a third timer (T3), a signal which is released thereby and selbt an enable signal for switching the drive motor (M) of the lubricating pump delivers the next braking operation; the third timing signal sums the time duration of successive braking operations, in which the drive motor of the lubricant pump is turned on, compares the sum of the time period with a predetermined working time (t3), and outputs a signal to the second timer (T2) upon reaching the predetermined work time, thereby the output from the second timer enable signal and thereby also the enable signal for switching on the motor driving the lubricating pump disappears.
