Definitions
- the invention relates to a disc brake for a commercial vehicle according to the preamble of claim 1.
- a brake caliper also referred to as a sliding caliper, of a generic disc brake is secured by means of fastening elements on a vehicle-side, i. stationary brake carrier held.
- guide rails are attached to the brake carrier in particular by screwing, on the other hand, are guided in plain bearings of the caliper so that this, relative to a rotationally held on an axle of the vehicle brake disc is axially displaceable during braking.
- One of the bearings is designed as a fixed bearing with little sliding play and serves mainly the axial guidance of the caliper, the bearing clearance is kept as low as possible.
- the other plain bearing however, has as a floating bearing due to a larger bearing clearance, since in addition to the axial guidance and tolerance compensation as well as thermally induced expansions are taken into account.
- the provision of the guide bush and its installation can be realized only with considerable effort, resulting alone due to the relatively many components of the guide bush, consisting essentially of the mentioned metallic bearing sleeve, the associated slide bushing made of plastic and the stop ring, high production costs.
- a relatively accurate machining of both the bearing sleeve and the brake caliper side bore is required.
- the said shoulder of the bore against which the stop ring abuts is likewise to be produced only with a corresponding manufacturing outlay, that is to say the bore must be formed as a stepped bore.
- the assembly of the guide bushing does not meet the requirements for a cost-optimized processing in terms of their cost.
- the invention has for its object to further develop a disc brake of the generic type so that it is conceptually simplified and their production and assembly easier and thus cheaper.
- the necessary for the Loslagerbetweenn tasks sliding bush is quasi part of the guide rail, resulting in a whole range of advantages.
- These include, first of all, the simplified production of the movable bearing, since essentially only the guide rail and the slide-secured against sliding bushing must be made. This is preferably done by molding the guide rail with plastic to form the sliding bush, wherein according to a development of the invention, the guide rail has a circumferential groove whose width corresponds to the desired width of the sliding bushing. The laterally delimiting walls of the groove form a stop for a displacement protection, but at the same time serve as a safeguard against squeezing the slide bushing.
- grease grooves are provided on the outside of the sliding bush, which preferably run obliquely in a conventional manner and serve to absorb grease, in order to enable a low-friction displacement of the caliper on the sliding bushing.
- the grease grooves are bounded by at least one circumferential sealing lip, i. closed on the front side, by the one hand, a leakage of the grease is prevented and on the other hand, the grease grooves from penetration of
- the assembly cost of the floating bearing is also significantly reduced overall, i. possible in a very short time. This is mainly due to the fact that the guide rail with integrated slide bushing merely has to be pushed into the brake caliper bore or the caliper must be pushed onto the guide rail already connected to the brake carrier.
- the invention leads to a remarkable cost savings in the manufacture of the disc brake.
- the functionality remains, as it is given in a disc brake according to the prior art, completely preserved.
- the width of the bushing is arbitrary and only determined by the specification of a sufficient investment on the wall of the brake caliper side bore, which in turn is determined by a sufficient operability.
- Figure 2 shows a part of the disc brake in an exploded view
- FIG. 4 shows an enlarged detail corresponding to the marking "B" in FIG. 3
- Figure 5 shows a part of the disc brake in different views.
- FIG. 1 shows a disc brake for a commercial vehicle is shown, which has a brake caliper 2 in its basic structure, which summarizes a brake disc 3, which is secured against rotation on an axis, not shown, of the utility vehicle.
- the caliper 2 is arranged on a stationary brake carrier 1 of the commercial vehicle, relative to the brake disc 3, axially displaceable.
- a fastening element is designed as a fixed bearing 4 and the other as a floating bearing 5.
- the floating bearing 5 For supporting the guide beam 6, i. for the axial guidance of the caliper 2, the floating bearing 5 has a sliding bushing 7 made of a plastic, preferably an elastomer, which is held displaceably on the guide rail 6 in accordance with the invention, as can be seen particularly clearly in FIG. This figure shows the guide rail 6 with the sliding bush 7 immediately before assembly.
- a circumferential groove 12 is inserted in the shell of the guide rail 6, on the walls of which the sliding bush 7 supported.
- the slide bush 7 has a plurality of fat grooves 10 on its outer side facing the wall of the bore 9, which run obliquely relative to a center axis of the sliding bush 7. These Fettnuten 10 are evenly distributed over the circumference.
- the fat grooves 10 are closed at the end by circumferential sealing lips 8, of which several, juxtaposed on each side are formed. These sealing lips 8 are used both to prevent the escape of grease from the Fettnuten 10 as well as their seal to prevent the penetration of dirt.
- the slide bush 7 is expediently produced by injecting the guide rail 6 in the region of the groove 12.
