Compressed-air brake device, and motor vehicle comprising such a compressed-air brake device

Abstract

The invention relates to a compressed-air brake device (1) for a motor vehicle, in particular a utility vehicle, with a pneumatic front axle brake circuit (3) and at least one pneumatic rear axle brake circuit (5), wherein a first valve device (7.1) is arranged fluidically between the front-axle brake circuit (3) and the rear-axle brake circuit (5), the first valve device being configured to be switched from a normal state in which the rear-axle brake circuit (5) is fluidically separated from the front-axle brake circuit (3) to a failure state in response to a trigger signal, wherein in the failure state the rear-axle brake circuit (5) is fluidically connected to the front-axle brake circuit (3) in such a way that the rear-axle brake circuit (5) can be supplied with supply air fed from the front-axle brake circuit (5) as failure brake air for the pneumatic braking of at least one rear axle.
