Problems solved by technology

[0006] The above-mentioned solutions all have the disadvantage that additional parts are required for fixing the annularly surrounding sealing area
This increases assembly costs in addition to the cost of the accessory and there is a risk that damage to the sealing area may occur when the separate accessory is installed, and it may also cause loosening of the seal, for example, when the accessory is used in the field from the rubber seat. disengagement on shedding, resulting in the loss of the desired pretension in the radial
This results in leaks which affect the sliding function of the caliper relative to the guide pin
[0007] A further disadvantage is the fact that the contact surfaces for force and form fit between the guide pin and the mounting area are not protected, easily leading to corrosion and rusting

Embodiment Construction

[0030] As already explained above, figure 1 A disc brake is shown with a brake caliper 1 , a carrier 2 , two guide pins 3 , 3 , two seals 4 , 4 and two cylindrical bolts 5 , 5 . Inside the brake caliper there is a pressing device, which is not further explained here, which is realized in the known manner in disc brakes of commercial vehicles by means of an eccentrically acting torsion bar pressing.

[0031] figure 2 The fixing of the seal 4 is shown in detail. According to this figure, the seal 4 is inserted into the annular groove 6 and surrounds the guide pin 3 in the form of a ring. The seal is elastically pretensioned in the radial direction in this annular groove 6 . Ring 7 is used for safeguarding. The guide pin 3 is inserted into the bead-shaped recess 8 of the carrier 2 with force and form fit and fixed with a cylindrical screw 5 . exist figure 2 The cylindrical bolt 5 for fixing the guide pin 3 in the groove 8 of the bracket 2 is not shown for the sake of clar...

Abstract

The invention relates to a disk brake, in particular for utility vehicles, having a carrier, a caliper, a holder device for displaceably holding the caliper on the carrier, a seal which is fixed in a recess on the holder device, and a pretensioning device for pretensioning the seal in the recess, wherein the pretensioning device is activated by the mounting of the holder device.

Description

technical field [0001] The invention relates to a disc brake, in particular a disc brake for commercial vehicles, having a bracket; a brake caliper; holding means for movably holding the brake caliper on the bracket; a seal in a groove on the retaining device; and pretensioning means for pretensioning the seal in the groove. Background technique [0002] figure 1 A partial cross-sectional view of this type of disc brake is shown. As shown in the figure, there is a brake caliper 1 comprising a brake disc, which is held axially displaceably on a fixed support 2, more precisely by means of two holding devices, wherein the holding devices are always Directly or indirectly fixed to the bracket 2 and present as a guide pin 3 extending away from the brake disc, it contacts the brake caliper 1 directly or indirectly in an opening similar to a sliding bearing. In the area between the brake caliper 1 and the carrier 2 there is a bellows-shaped enveloping seal 4 . [0003] figure...
