Description
BRAKE ASSEMBLY FOR VEHICLE WHEELS The invention relates to a brake assembly for wheels of vehicles, in particular of vehicle trailers, and vehicles having a stationary brake calliper and guided brake pads.
Removal of one or more axially slidable brake discs from a stationary brake calliper, due to wear or for other reasons, is effected in known manner by removing the brake calliper and subsequently demounting the brake disc.
The invention has as an object to provide a brake assembly for wheels of vehicles, in particular of vehicle trailers, in which installation and removal of one or more brake discs into and from the brake calliper, respectively, is accomplished in simple manner.
Therefore, the invention provides for a brake assembly for a wheel axle, including: a stationary brake caliper; 15 at least one pair of brake pads received within the caliper; at least one brake disc located between the brake pads, said disc, in use, being in fixed rotational relation and displaceable axial relation to an axle of the wheel wherein 20 after removal of the brake pads and the wheel, the caliper is shaped and has internal dimensions such as to permit the at least one brake disc to be reoriented from an in-use position within the caliper to an inclined position, relative to the wheel axle whereupon the brake disc is removable from said caliper in said inclined position.
The advantages which are mainly achievable with the invention are to be seen in that one or more brake discs can be taken off a wheel axle after removal of the wheel hub, whilst the brake calliper remains unchanged, that is with the brake calliper remaining installed. In order to achieve this, the brake pads of the brake disc(s) are removed so that the brake disc remains unsupported within the brake calliper. In order to remove the brake discs it is in particular not necessary to first remove a blocking element for the brake disc, such as is provided for 7fixed/stationary brake discs using axially displaceable brake callipers.
la In order to prop the unsupported brake disc within the brake calliper, a support element can be fastened to the calliper, which can grip the brake disc(s) at their under side, such that the installation position is maintained.
In order to remove the brake disc, the disc can be tilted on the wheel axle from a vertical mounting position into inclined removal positions, since a free space is created within the brake calliper following removal of the brake pads and separation of the disc's bearing on the wheel hub. In these removal positions, propping of the disc is accomplished at least at the terminal end of the wheel hub.
The brake disc is tilted into the inclined positions for its removal, such that it can be slipped past a front abutment wall of the brake calliper.
i°o°° o eoeoo* o eoe° In order to prevent damages to the terminal end of the wheel axle during withdrawal of the brake disc from the brake caliper, the terminal end of the wheel axle is provided with a protective sleeve or other type of cover on which the brake disc can be slidably pulled out.
In order to install the brake disc or discs, this process is accomplished in reverse order of steps as used in the removal procedure.
A centering element in provided on the wheel axle in order to permit easy mounting of the wheel hub onto the wheel axle after the brake disc or discs have been installed. In particular, the centering element is arranged to thread the hub bearing in alignment onto the wheel axle. The hub bearing is centered in relation to its bearing seat by means of the centering element before the wheel hub achieves engagement with the brake discs. To achieve this, the centering element is provided with a beveled front edge.
The centering element is in particular shaped to have the same diameter as the hereto adjoining portion of the wheel axle, which portion forms the bearing seat. Instead of the centering element, the outer contour of the wheel axle can also be shaped such that the portion of the wheel axle which forms the bearing seat is lengthened. Heretofore, the lengthened portion can have a diameter that is somewhat smaller than the bearing seat.
The brake assembly may incorporate a plurality of brake discs, all of which can be inclined sequentially in order to dismount and remount these.
One embodiment of the invention is illustrated in the accompanying drawing and described hereinbelow.
In the drawing: Figure 1 shows a plan section of a brake assembly in an assembled state; Figure 2 shows a plan section of the brake assembly of figure 1 in which the wheel hub has been removed; Figure 3 shows a plan section of the brake assembly without wheel hub and with two brake discs and interleaving brake pads; Figure 4 shows a plan section of the brake assembly with dismounted brake pads and with the brake discs in their vertical mounting position, as well as a protective sleeve and a centering element on the wheel axle; 4 "I T AY M' "MIMMIR 3 Figures 5-9 show intermediate positions of the brake disc during its removal from the brake caliper; Figure 10 -shows an illustration of the wheel axle with a centering element; Figure 11 -shows a schematic illustration of the brake assembly with support element for the brake discs; and Figure 12 shows a further schematic illustration of the support element for the brake discs, in a bottom view.
The brake assembly 1 includes brake discs 3, 4 (see figure 1) which are axially displaceable but rotationally stationary mounted on a wheel hub 2.
However, it is possible to have only one brake disc or more than two brake discs arranged within the brake caliper 5. A number of brake pads 6-9, as illustrated in figure 1, are arranged in between brake discs 3, 4 and located on the outside of the associated brake disc.
To dismount the brake disc 3 or 4, or both brake discs 3 and 4, the wheel hub 2 is dislodged from the wheel axle 10, as is illustrated in greater detail in figure 2. A holding clamp of the brake caliper 5 is subsequently loosened and the brake pads 6-9 removed, as is illustrated in figure 4.
The stand-alone brake discs 3 and 4 can now be removed, whereby these are tilted from their vertical mounting position i through intermediate, inclined demounting positions i i v, as is individually illustrated in figures 6 to 9.
In order to prevent the brake discs 3, 4 from falling onto the wheel axle after the wheel hub 2 has been removed from the wheel axle 10, a support element 20, which is shown in figures 11 and 12, can be located beneath the brake discs. Support element 20 consists of a shell 21 which under-grips the brake discs 3, 4 in their mounting position, shell 21 being supported by an angled holder 22 which is to be removably fastened to the brake caliper 5 (see figure 11).
The terminal end of the wheel axle 10 is provided with a protective sleeve 11 or similarly acting protection element in order to prevent damages occurring during removal and mounting of the brake discs 3, 4, such as is shown in figures 5-9. The brake discs can bear slidingly on the protective sleeve during mounting and removal thereof.
A centering element 12 (see figure 10) is provided to achieve aligned (centered) assembly of the wheel hub 2 onto the wheel axle 10 and in order to thread the wheel hub onto the wheel axle 10. Centering element 12 is provided at a shoulder or relieve 13 of the wheel axle 10 and has on its front face a bevel 14 which simplifies threading of the bearing 15 at the wheel hub 2 onto the bearing seat 16 at the wheel axle 10, the bevel 14 concentrically aligning the bearing 15 in relation to the bearing seat 16 before the wheel hub 2 achieves engagement with the front brake disc.
The installation procedure of the brake discs 3, 4 corresponds in reversed sequence to that of the removal (dismounting) procedure of brake discs 3 and/or 4.
The dismounting procedure of brake discs 3, 4 comprises the following steps. First, wheel hub 2 is detached from wheel axle 10. The support element of figures 11 and 12 props under the brake discs 3, 4. Subsequently, the brake pads 6-9, which are shown in. figure 1, are removed from the brake caliper Subsequently, the front brake disc 3 is tilted from its vertical mounting position i (see figure 5) into a first, inclined removal position ii (see figure The brake disc 3 is hereby able to bear on the wheel axle 10 at its protective sleeve 11.
Through further inclining of the brake disc 3 into its dismounting positions iii-v (see figures 7 to 9) it is possible to pull off the disc from the brake caliper 5 past the abutment wall 5a of brake caliper 5. Hereafter, the further brake disc 4 is removed from brake caliper 5 in corresponding manner.
