Definitions
- the present invention relates to a disc brake, in particular for a commercial vehicle according to the preamble of claim 1.
- disc brakes of the caliper also called sliding caliper
- the brake carrier which is connected to the vehicle.
- guide rails engage in the brake carrier, which are guided on the other hand in plain bearings of the caliper so that an axial displacement of the caliper to the stationary brake carrier is possible.
- plain bearings one is designed as a fixed bearing with little sliding clearance, while the other acts as a floating bearing, which in particular manufacturing tolerances are compensated.
- the spring causes a damping shocks, as they usually occur when driving.
- the sliding ring and with it the guide rail is held under tension in a certain position, so that disturbing rattling noises are avoided.
- the spring is preferably formed meander-shaped and completely surrounds the slide ring in its width, wherein the individual spring legs lie in areas on the sliding ring, in which an axis compensation takes place, as he to compensate for manufacturing tolerances, but also to compensate for changes in the position Guide Holms to the guide sleeve is required transversely to the axial direction of movement of the guide rail. Due to the adjacent resilient legs of the Achsaus GmbHshub is limited to some extent. The present invention is therefore based on the object to develop a disc brake of the generic type so that the operability of the floating bearing is improved.
- Claim 1 has.
- the tabs are shaped so that the spring action also occurs when Achsaus GmbH.
- the corresponding stroke is through
- the tabs are arranged on opposite sides of the seal ring or fixedly connected to the brake caliper component, which expediently has the form of a retaining ring.
- the spring may consist of two approximately uniformly shaped parts, each of which has a bracket and two end-connected tabs, which lie in the mounted position on each other, so overlap.
- This production of the spring offers the advantage of an extremely cost-effective production, wherein in principle the spring can first be manufactured in one piece and in a further manufacturing step is divided so that two substantially equal half-parts arise.
- the receptacle of the caliper or of the component fastened therein can be provided with a corresponding locking means.
- This consists according to a preferred embodiment of the invention of a plastic cage, which is vulcanized into the component and has the recesses for receiving the resilient tabs.
- the recordings correspond in shape and dimension to the associated tabs.
- FIG. 1 shows a partial longitudinal section through a disc brake according to the invention
- Figure 2 is a detail of the disc brake in a longitudinal section
- Figure 3 shows a further detail of the disc brake in a plan view
- Figure 4 shows a part of the detail of Figure 3 in a perspective view
- Figure 5 is a detail of Figure 2 in a perspective view
- Figure 6 shows an exemplary embodiment of a spring of the disc brake in an exploded view
- FIG. 1 shows a disk brake, in particular for a commercial vehicle, which has in its basic structure a brake caliper 2 which comprises an internally ventilated brake disk 1 which is fastened to an axle (not shown) of the utility vehicle.
- the caliper 2 is on a brake carrier 7 of the commercial vehicle, based on the
- Brake disc 1 axially slidably connected.
- fastening elements 5, 6 are provided, of which the fastening element 5 is designed as a movable bearing and the fastening element 6 as a fixed bearing.
- Both fastening elements 5, 6 each have a guide sleeve 8, 9 and a guided therein guide rail 10, wherein the guide sleeves 8, 9 are held in holes 3 of the caliper 2.
- the guide rails 10 are screwed into the brake carrier 7 and thus fixed relative to the caliper 2, while the guide sleeves 8, 9 are fixedly connected to the caliper 2 and are therefore mounted axially displaceably on the guide rail 10 together with the caliper 2.
- the guide sleeve 8 of the movable bearing 5 is shown, wherein the guide sleeve 8 has a slide ring 11 which surrounds the mattersshohn 10.
- a Swtftihrung 14 which is shaped like a sleeve and on the side of a shaft 16 of the effetshohns 10 is supported.
- a support ring 17 is arranged, which surrounds the slide ring 11 in this end and on the other hand rests with a lip on the guide rail 10.
- the movable bearing allows, for example for tolerance compensation, an axial displacement of the guide rail 10, corresponding to the arrow marking transversely to the axial displacement direction.
- a spring 12 is provided which abuts in regions on the outer surface of the seal ring 11 and opposite to the inner wall of a retaining ring 13 which surrounds the seal ring 11 concentrically and in the bore 3 of the Caliper 2 is inserted.
- the spring consists of a sliding ring 11 at least partially surrounding bracket and attached, extending in the longitudinal axis of the slide ring 11 tabs 19, the areas abut the sliding ring 11 and on a component of the caliper 2 performing retaining ring 13.
- the contoured spring 12 can be seen in plan view. There is also seen that the spring consists of two half-parts, as shown as a detail in the figure 6.
- each half part has a circular segment-shaped bracket 18, at the respective end of which a tab 19 connects, wherein the associated bracket 18 forms an upper boundary of the tabs 19.
- the half pieces are dimensioned so that in the assembled state always two tabs
- FIG. 5 shows an axle compensation, which is enforced by an angle error, in which the shaft 16 deviates from the axis parallelism with respect to the retaining ring 13 fixed in the brake caliper 2.
- an angle error in which the shaft 16 deviates from the axis parallelism with respect to the retaining ring 13 fixed in the brake caliper 2.
- a preferably made of plastic cage 20 is provided in the retaining ring 13, which is fixedly connected to the retaining ring 13 and has two opposing seats 21, in each of which the lugs 19 of the spring 12 eino against rotation.
- This cage 20 is preferably vulcanized.
