Embodiment Construction

[0029] specific implementation plan

[0030] figure 1 and figure 2 An axle modulator 10 according to the invention is shown as an example. This is a block diagram in which only the outlines of the essential components of the invention are shown.

[0031] Since such an axle modulator 10 is provided for adjusting the brake pressure corresponding to the brake cylinders of an axle or a plurality of axles, the axle modulator 10 typically has a function for actuating with compressed air. Corresponding valve or valve output. Corresponding inlets for supplying compressed air are likewise not shown here. The control or regulation of the axle modulator 10 itself is carried out by an integrated regulating unit. This is an electronic controller, also not shown here, which evaluates the sensor data on the one hand and calculates the required brake pressure on the other hand.

[0032]In addition, the valve itself is also actuated for setting the brake pressure in the brake cylinder. ...

Abstract

The invention relates to an axle modulator (10) for open-loop control of the brake cylinder pressure on one or both sides of at least one axle of a vehicle with a preferably pneumatic brake apparatus.RPM sensors (12, 13) and brake liner wear sensors (14) can be readably connected. The axle modulator (10) is characterised in that separate connections (11a; 11b) are provided for active and passiveRPM sensors (13; 12). The invention further relates to an open-loop control unit for an axle modulator (10). Finally, the invention relates to a braking system with at least one brake controller and aleast one open-loop control unit according to the invention and / or an axle modulator (10) according to the invention.

Description

technical field [0001] The invention relates to an axle modulator according to the preamble of claim 1 . Furthermore, the invention relates to a regulating unit for an axle modulator having at least one regulating unit according to the preamble of claim 15 . Finally, the invention relates to a braking system according to the preamble of claim 16 having at least one brake control unit and at least one axle modulator. Background technique [0002] Vehicle Electronic Braking Systems (EBS) are manufactured in different varieties. Pneumatic brake systems are typically used in particular for heavy vehicles, such as trucks, buses or the like. For actuating the individual brake cylinders at the wheels, so-called axle modulators (AxM) are typically provided here. They serve to regulate the brake cylinder pressure on both sides of the individual wheels in the form of an axle or axles. For this purpose, the axle modulators for the axles typically have two pneumatic independent pres...
