Abstract

A partially lined motor-vehicle disk brake of the first caliper type, with a housing including an actuator system as a normal force generator mounted in a slidably guided fashion on a holder, with at least one friction lining which is configured in a hammerhead shape with claws and which is accommodated in a guided fashion with pull-support in holder arms with receptacle recesses in the holder. In order to avoid reversing clicks, the holder is embodied as a closed frame in that holder webs connect the holder arms to one another, and the holder webs are positioned tangentially in front of the housing limbs of the housing. Accordingly, the force flux in the holder is closed, and in the case of pull suspension all the holder arms are nevertheless included in the force flux.

First claim

The invention claimed is:

1. A partially lined motor-vehicle disk brake with a brake caliper as a normal force generator, whose housing which is configured in a U shape, with housing limbs and with a housing bridge which connects the two housing limbs, engages in a U shape around a friction ring and activates at least one associated friction lining via a backplate which bears friction material and has tangentially protruding, hammerhead-shaped claws for providing pull-support for the braking forces in a holder, wherein the brake caliper is mounted so as to be slidable axially relative to the holder, and wherein the holder has a holder profile which comprises in each case an inflow-side holder arm and an outflow-side holder arm with receptacle recesses, which have bearing faces and/or support or guide faces including abutments and into which the claws are fitted, such that application of a tangentially directed circumferential force to the holder profile induces tensile loading in a claw, and vice versa, wherein the holder is embodied as a closed frame in that holder webs connect the holder arms to one another, and the holder webs are positioned tangentially in front of the housing limbs of the brake caliper, wherein a two-point bearing, contact points of which are defined at a distance from one another on the hammerhead-shaped claws, is provided between the brake caliper and friction lining, each of the contact points comprising a convex surface on a rear side of the respective hammerhead-shaped claw and a corresponding concave surface on the housing bridge.

2. The partially lined motor-vehicle disk brake as claimed in claim 1 , wherein the holder webs are provided integrally on the holder arms.

3. The partially lined motor-vehicle disk brake as claimed in claim 1 , wherein an axially external holder web is detachably secured to the two holder arms.

4. The partially lined motor-vehicle disk brake as claimed in claim 1 , wherein a leaf spring is clamped in between the brake caliper and holder, said leaf spring being provided elastically pre-loaded in a radial direction R between the housing limb and holder.

5. The partially lined motor-vehicle disk brake as claimed in claim 4 , wherein the leaf spring is accommodated in at least one positively locking forced guidance means and/or receptacle between the holder and brake caliper.

6. A friction lining with hammerhead-shaped projections which contain claws for providing pull-support in a holder, wherein the friction lining has bearings on a rear side of its hammerhead-shaped claws, wherein two claws which are arranged tangentially at a defined distance from one another define a two-point bearing for a brake caliper on their rear sides, each contact point of the two-point bearing comprising a convex surface on the rear side of the respective hammerhead-shaped claw.

7. The friction lining as claimed in claim 6 , wherein each hammerhead-shaped claws further defines a bearing surface on the rear side thereof which is configured to contact a corresponding bearing face of a holder profile of the holder.

8. The friction lining as claimed in claim 6 , wherein the convex surfaces on the rear side of the respective hammerhead-shaped claw define a V-shaped receptacle for receiving a housing bridge of the brake caliper.
