Abstract: A lamella for use in a vehicle tire vulcanization mold has projections and depression, wherein the height of the projections and the depth of the depressions extend substantially parallel to a peripheral surface of the tire tread of the vehicle tire to be molded in the vulcanization mold. Each one of the projections has a highest point-shaped location or top. Each one of the depressions has a lowest point-shaped location or crater. The projections and depressions are distributed according to a substantially uniform areal division. The areal division is defined by dividing lines extending in a dividing plane preferably centrally positioned between a first plane defined by the tops and a second plane defined by the craters. The dividing lines are comprised of three sets wherein the dividing lines within each one of the sets extend parallel to one another and wherein the dividing lines of different ones of the sets intercept one another at an angle of substantially 60° so that a grid of triangles is formed.

Abstract: A motor vehicle air spring has an air volume subdivided into an air spring volume and an ancillary volume. The two volumes (4, 6) are connected to each other by a line (8) having a cross section which can be switched or continuously adjusted by a valve (12). The valve (12) has two roll membranes (56, 58) which are arranged in mutual opposition. The intermediate space (60) between the roll membranes (56, 58) preferably communicates with the atmosphere. The two mutually opposingly mounted roll membranes (56, 58) can be joined to form a single double roll membrane (76). Preferably, the valve body (34) as well as the bore (62) of the valve housing (36) is configured so as to be cylindrical so that the constant effective diameter (Dw) of the roll membranes (56, 58) results which is independent of the deflection of the valve body (34).

Abstract: The invention is directed to a method for controlling the level of a vehicle body of a motor vehicle with a level control system having a plurality of actuator elements with which the level of the vehicle body can be lowered by discharging an actuating fluid from the actuator elements. The level control system includes a control unit. A first level of the vehicle body is determined relative to a reference point directly before a discharge operation. A discharge operation of the vehicle body is initiated when the first level lies above a pregiven level. After initiating a discharge operation, a check is made in the control unit as to whether the vehicle body has lowered from the first level in accordance with an input. The discharge operation is interrupted when the vehicle body has not lowered from the first level in accordance with the input.

Abstract: The invention relates to a method for transmitting data in a data transmission system. The invention also relates to a data transmission system which includes a receiver (2) and at least one transmitter (4a to 4d). The receiver (2) is operable in a stand-by mode and in a data-receive mode and transfers with the aid of a switch-on signal from the stand-by mode into the data-receive mode. The transmitters (4a to 4d) transfer, via a data transmission, information to the receiver (2) as to when, after this data transmission, the next data transmission is to be expected from the corresponding transmitter (4a to 4d). The switch-on signal is generated in the receiver (2) shortly ahead of the time point at which the next data transmission is to be expected from the transmitters (4a to 4d) so that the receiver (2) transfers from the stand-by mode into the data-receive mode.

Abstract: The invention relates to a method for monitoring the air pressure of a tire of a motor vehicle with a tire pressure control system. The invention further relates to a motor vehicle having a tire pressure control system with which the method can be carried out. The tire pressure control system includes tire pressure control devices (4a to 4d) on each of the wheels (2a to 2d), which transmit to a central unit, at regular intervals, a data transmission which contains, inter alia, the air pressure measured in the tires.
