Embodiment Construction

[0029] Belonging to the disc brake according to the invention is the figure 1 In the first embodiment shown there is a brake caliper 10 , two brake pads 12 , 14 , two hold-down springs 16 , 18 and hold-down bow 20 . Press the bow 20 in the radial direction, that is to say in figure 1 The middle is downward, so that the compression springs 16 and 18 are pretensioned. Between the brake pads 12 and 14 there is a brake disc (not shown). The pressing bow 20 also serves as a loss prevention device for the brake pads 12 and 14 , in particular in the event of a breakage of the pressing springs 16 , 18 .

[0030] The pressing bow is held on the pressing side in a slot 22 whose radially outer wall 24 absorbs the prestressing force.

[0031] On the rim side, a projection 26 is formed on the brake caliper 10 , which likewise has a slot 28 . The radially outer wall 30 of the slot 28 in turn serves to absorb the reaction force of the prestressing force.

[0032] In the two slots 22 and...

Abstract

The invention relates to a disc brake, more particularly for commercial vehicles, comprising a brake calliper (10), at least one brake pad (12, 14), a hold-down spring (16, 18) that holds the brake pad down in the radial direction relative to a brake axis, a hold-down bar (20) that biases the hold-down spring in the radial direction, a first retainer (22, 24) on the brake calliper (10) that supports the hold-down bar (20) radially outwardly, and a second retainer (28, 30) with a stop on the brake calliper (10) that supports the hold-down bar (20) radially outwardly but not in the axial direction, wherein the first (22, 24) or the second (28, 30) retainer has a stop (32, 34) that acts in a first axial direction. According to the invention the hold-down bar (20) has a first projection (36) which is supported axially against the hold-down spring (16) in a second axial direction opposite to the first axial direction, and / or a second projection (38) which is supported in the second axial direction but not radially outwardly against the brake calliper (10).

Description

technical field [0001] The invention relates to a disc brake, in particular for commercial vehicles, having a brake caliper, at least one brake pad, a compression spring holding the brake pad in a radial direction with respect to the brake axis , a pressing bow that pretensions the pressing spring in the radial direction, a first holder on the brake caliper and a second holder on the brake caliper with a stop, the first holder being supported radially outwards The pressing bow, the stop radially outwards but not supporting the pressing bow in the axial direction, wherein the first or the second holder has a stop acting in the first axial direction. Background technique [0002] The above-mentioned pressing bow means that it must be a sufficiently bending-resistant component in order to prestress the pressing spring in the radial direction. A radial direction is not necessarily to be understood here as a direction which lies radially on the brake axis with mathematical preci...
