Problems solved by technology

In addition, locking on only one side of the car creates a potential risk of trailer tail-spinning on slippery surfaces, because the locked wheels create a moment about the vertical axis of the trailer that can destabilize the entire vehicle system

Embodiment Construction

[0038] In the figure, the pneumatic and electrical connections to the towing vehicle are shown on the left. The compressed air connection marked with the term "SUPPLY" is used to connect the compressed air supply line of the towing vehicle. The connection labeled "SERVICE" is used to connect the service brake line of the towing vehicle. The service brake pressure set by the driver of the tractor vehicle via the brake pedal is transmitted to the trailer via the "SERVICE" connection and is supplied to the EBS modulator 2 via the compressed air line 4 . Furthermore, an electrical connection to the towing vehicle is provided, which is designated by the term "ISO 7638". The standard "ISO 7638" refers to the standardized interface between traction vehicles and trailers in the field of commercial vehicles. The service brake pressure of the towing vehicle, which is generated, for example, by the driver of the towing vehicle via the brake pedal, is transmitted via these interfaces as...

Abstract

The invention relates to a pneumatic brake system for a trailer vehicle and to a brake control modulator for such a brake system. Taking this as a starting point, the invention specifies a pneumatic brake system for a trailer and a brake control modulator which permit a full braking action of the trailer with anti-lock function even in an emergency braking situation. For this purpose, a spring store neutralizing valve (7) is provided, by means of which the compressed air filled into the spring store cylinder by an electronic control device (2) can be at least partially held.

Description

technical field [0001] The invention relates to a pneumatic braking device for a trailer vehicle and to a brake control modulator for such a braking device. Background technique [0002] Such a braking device is known, for example, from DE 103 56 672 B4. [0003] Such pneumatic trailer brakes usually have an emergency braking function which automatically brakes the trailer when the compressed air supply line is disconnected from the towing vehicle. Emergency braking is generally triggered when the supply line fails, which leads to a severe pressure loss. Depending on the design of the brake system, emergency braking is produced either by the service brake function or by the trailer's spring accumulator brake function. During emergency braking with the service brake function, compressed air is automatically and controlledly introduced from the trailer's storage tank into the service brake cylinders. [0004] The brake system known from DE 103 56 672 B4 can alternatively be...
