PNEUMATIC BRAKING SYSTEM

Abstract

The disclosure relates to a brake system for vehicles, comprising a brake unit. In order to provide a new brake system, which is in particular more lightweight and more environmentally friendly, a brake unit is proposed which comprises at least a brake disc and a brake piston unit, a compressed air reservoir, and a control unit in order to pressurise the brake piston unit with compressed air from the compressed air reservoir on demand.

Claims

1. A brake system for vehicles, comprising a brake unit which comprises at least one brake disc and a brake piston unit, a compressed air reservoir, an actuating unit, and a control unit in order to pressurise the brake piston unit with compressed air from the compressed air reservoir on demand.

2. The brake system according to claim 1, wherein the compressed air reservoir provides air with a pressure of less than 25 bar.

3. The brake system according to claim 1, wherein the brake system comprises several compressed air reservoirs.

4. The brake system according to claim 1, wherein the brake system comprises an emergency compressed air reservoir.

5. The brake system according to claim 4, wherein an emergency compressed air reservoir is provided for each wheel.

6. The brake system according to claim 1, wherein the brake system is designed as a multi-circuit system.

7. The brake system according to claim 6, wherein the brake system is designed as a four-circuit system.

8. The brake system according to claim 1, wherein the actuating unit can be operated manually.

9. The brake system according to claim 1, wherein the brake piston unit comprises a piston with a non-circular cross section.

10. The brake system according to claim 9, wherein the brake piston unit comprises a piston with an elliptical piston area.

Description

DRAWINGS

[0026] The drawings described herein are for illustrative purposes only of selected embodiments and not all possible implementations, and are not intended to limit the scope of the present disclosure.

[0027] Other advantages and features of the disclosure can be gathered from the following description on the basis of the figures. In these figures:

[0028] FIG. 1 shows a schematic representation of an exemplary embodiment of a brake system according to the disclosure.

[0029] Corresponding reference numerals indicate corresponding parts throughout the drawing.

DETAILED DESCRIPTION

[0030] Example embodiments will now be described more fully with reference to the accompanying drawing.

[0031] Purely schematically, a compressor or a compressed air source 1 is shown which fills a compressed air reservoir 2. For this purpose, the compressed air source 1 is connected to the reservoir by means of corresponding lines 3. A control unit 4 which, in the exemplary embodiment shown, can be actuated by means of a directly connected actuating member 5, can feed compressed air via the lines 8 from reservoir 2 to a cylinder 6, in which a piston 7 is guided. This may be the brake piston, which directly actuates a brake shoe. The brake shoe then acts on a disc of a vehicle, which disc is not shown here.

[0032] The exemplary embodiment shown also shows a generator 9 stylised as a radial impeller. The radial impeller may for instance be arranged in the dynamic pressure area of a vehicle and operate the compressed air source 1 designed as a compressor.

[0033] The described exemplary embodiment only serves a better understanding and is not restrictive.

[0034] The foregoing description of the embodiments has been provided for purposes of illustration and description. It is not intended to be exhaustive or to limit the disclosure. Individual elements or features of a particular embodiment are generally not limited to that particular embodiment, but, where applicable, are interchangeable and can be used in a selected embodiment, even if not specifically shown or described. The same may also be varied in many ways. Such variations are to be regarded as a departure from the disclosure, and all such modifications are intended to be included within the scope of the disclosure.
