Problems solved by technology

[0007] However, the aforementioned known cooling air guide system may not be used advantageously in many cases, since it cannot ensure a cooling air delivery independent of the springing state of the wheels, adversely affecting the vibration properties of the brake cover, especially the resistance to vibrations. Fatigue strength, complex design or excessive installation space requirements

Embodiment Construction

[0038] here figure 1 and 2 An exemplary embodiment of a cooling air guidance system 1 according to the invention is shown for a friction lining in the form of a disc brake 2 in a functionally installed state on the left side of the front axle of a passenger vehicle, which is formed as a strut axle. brake 2. The front axle has a damper strut 14 , which is supported with its lower end on the wheel carrier 3 or on the wheel carrier 3 , wherein, in the functionally installed state, the wheel carrier 3 passes through the damper strut 14 and a plurality of link rods (not shown here) are connected to the vehicle structure or body. Via hub 4 (reference figure 2 ), the wheel can be fastened on the wheel frame 3. exist figure 1 and 2 The damper strut shaft shown partially in the center is designed as a steerable shaft, that is, the wheel carrier 3 , which can also be referred to as pivot carrier 3 in this case, can pivot about a so-called support axis in order to be able to reali...

Abstract

The invention relates to a cooling air guide for a friction lining brake of a motor vehicle which vehicle has a wheel mount and a wheel hub attached to the wheel mount, wherein the friction lining brake has a brake body having friction surfaces, in particular a brake disc, which brake body is connected to the wheel hub of the motor vehicle, and a brake cover arranged on the inside of the brake body and fastened in a stationary manner to the wheel mount. The brake cover forms a first air guide apparatus of the cooling air guide. The cooling air guide has a second air guide apparatus which is arranged on a side of the brake cover facing away from the brake body and is fastened to the brake cover in a stationary manner. The second air guide apparatus is designed such that cooling air flowing in from the front, relative to a longitudinal vehicle direction, is directed through the second air guide apparatus toward the vehicle exterior to the first air guide apparatus and from there, via interaction of the first air guide apparatus with the second air guide apparatus, further toward the vehicle exterior to the brake body. In addition, the second air guide apparatus can have a scoop-shaped, primary air guide surface, which extends in the transverse vehicle direction close to the brake cover.

Description

technical field [0001] The invention relates to a cooling air guide system for a friction disc brake of a motor vehicle having a wheel carrier and a wheel hub connected to the wheel carrier, wherein the friction disc brake comprises a wheel hub connected to the wheel carrier of the motor vehicle with The brake body of the friction surface, in particular the brake disc, and the friction lining brake comprise a brake cover arranged on the inner side of the brake body and fastened in a fixed position relative to the wheel carrier, wherein the brake cover forms the cooling A first air guide of the air guide system, and the cooling air guide system has a second air guide arranged on the side of the brake cover facing away from the brake body and opposite the brake cover The position is firmly fastened. Background technique [0002] Cooling air guide systems for friction lining brakes comprising an air guide for improving the convective cooling of the brake body, in particular fo...
