Embodiment Construction

[0043] figure 1 Shown is the configuration according to the invention of a compressed-air operated parking brake system 1 of a commercial vehicle, not further shown here, comprising a spring accumulator cylinder 2 for for loading a brake not shown here in detail by spring force and for releasing the same brake by means of oppositely directed air pressure; and a parking brake device 3 for filling and emptying the spring accumulator cylinder 2 in order to The associated brake can be released and applied in an adjustable manner, ie, can be adjusted stepwise or continuously. Furthermore, the parking brake system has an emergency release device 4 for filling the spring accumulator cylinder 2 in the event of a fault of the parking brake system 1 involving such a spring accumulator cylinder 2 . Here, the emergency release device 4 and the parking brake device 3 are connected to the spring accumulator cylinder 2 via a reversing valve 5 , wherein ideally the shortest possible distance...

Abstract

The invention relates to a method for operating a compressed air-operated parking brake system (1) of a utility vehicle, comprising a parking brake device (3), by means of which compressed air is fedinto a spring brake cylinder (2) and said spring brake cylinder is vented, by way of which an associated brake is controllably released and applied. The invention further comprises an emergency release device (4) for feeding compressed air to the spring brake cylinder (2) during a malfunction of the parking brake device (3), wherein by means of the emergency release device (4), compressed air is fed to the spring brake cylinder (2) during the absence of such a malfunction. The invention further relates to a corresponding parking brake system (1) and to a vehicle.

Description

technical field [0001] The invention relates to a method for operating a compressed-air-operated parking brake system of a commercial vehicle, the parking brake system having a parking brake device by means of which compressed air is supplied into the spring accumulator cylinder and exhaust said spring accumulator cylinder, thereby releasing and charging the associated brake in an adjustable manner; and an emergency release device for applying compressed air to the Input into the spring accumulator cylinder. Furthermore, the invention relates to a corresponding parking brake system and a vehicle. Background technique [0002] The field of application of the invention relates to braking systems, in particular to parking brake systems of commercial vehicles, such as trucks or buses consisting of a tractor and trailer, or trucks without a trailer. [0003] Such commercial vehicles have a parking brake implemented by a parking brake function. In this case, the brake is applie...
