Description

"ROTOR DISK ASSEMBLY FOR FULL CONTACT BRAKE"
Technical Field
The present invention relates to a rotor assembly for a full contact brake, and more particularly, to a rotor assembly made out of two annular parts. Background Art
Heat remains a serious problem in full-contact brakes, that is, brakes having an annular rotor disk with a continuous radial annular friction surface adapted to be engaged by a continuous annular brake shoe. The rotor is generally mounted on a hub or hub adapter.
While the rotor is made of cast metal, the hub or hub adapter is usually fabricated of a light metal having different thermal expansion properties. Disclosure of the Invention
It is an aim of the present invention to provide a rotor assembly for a full-contact brake disk assembly wherein the rotor assembly is made in two parts allowing differential thermal expansions between the two parts.
It is also an aim of the present invention to provide a rotor for a disc brake construction having a generally symmetrical cross-section in order to reduce distortion in the brake caused by thermal growth.
A construction in accordance with the present invention comprises a rotor assembly including an annular rotor disk with inward projections, the rotor disk having at least one radial friction surface, a hub adapter having a cylindrical component and a radial rim, fastener means extending between the radial rim of the hub adapter and the inner projection of the annular rotor disk to connect the hub adapter to the annular rotor disk in order to permit differential thermal expansion to occur between the annular rotor disk and the cylindrical hub adapter. More specifically, the annular rotor disk is made of a first material and the hub adapter is made of a second material.
In another aspect of the present invention, there is provided a rotor assembly, for a full contact annular disk brake, comprising a hub adapter, an annular rotor disk connected to the hub adapter, the improvement comprising radial components on the hub adapter, the annular rotor disk having a complementary connecting means securing the annular rotor disk to the radial component on the hub adapter, the radial components on the hub adapter and the connecting means on the annual rotor disk including circumferentially spaced-apart pairs of symmetrical, axially spaced-apart members on one of the rotor disk and the hub adapter; and circumferentially spaced-apart unitary members on the other of the rotor disk and hub adapter; and each unitary member adapted to fit between a corresponding pair of axially spaced-apart members; a first set of aligned bores extending through each pair of axially spaced-apart members and a second bore extending through the corresponding unitary member and adapted to be aligned with the first set of bores, and whereby one of said first set of bores and said second bore having an oblong configuration with a major axis in a radial axis to allow thermal radial expansion of the rotor disk and a fastener pin extending through the aligned bores to secure the rotor disk to the hub adapter.

Fig. 9 is an enlarged, fragmentary, perspective view of the embodiment of Fig. 8. Mode for Carrying out the Invention
The brake assembly 10 as shown in the drawings includes an annular rotor disk 12 and a hub adapter 14. The annular rotor disk 12 includes radial apertures 16 defining cooling fins 18 therebetween. A pair of opposed radial friction surfaces 20, 22 extend uninterrupted about the annular rotor disk 12.
In the annular rotor disk assembly 10, both elements can be made of different materials. The hub adapter 14 could be made of aluminum while the rotor disk 12 could be made of a more wear-resistant cast material, such as steel. The rotor disk 12 also includes radially inwardly extending scalloped mounting brackets 24 provided with bores 26. The hub adapter 14 has an axial component and a radial component. The radial component is a continuous annular rim 28 that extends in a radial plane. The axial component is a cylindrical member 30. Cooling fins 32 are provided on the cylindrical member 30 while cooling fins 34 are provided on the radial rim 28. Splines 36 are provided on the inner cylindrical surface of the cylindrical member 30 to engage a hub of a driven wheel. The radial rim 28 is provided with bores 29 that correspond with the bores 26. The brake assembly is cooled by air flowing about the brake assembly and through the disk by means of apertures 16. Cooling is effected by air moving past the cooling fins 32, 34, and 18.
The bores 26 are somewhat oblong, that is, having a longer radial axis than the tangential axis. Bolts 38 extend through the bore 26 and the bore 29 in the radial rim. The bolt 38 cooperates with a threaded sleeve 44 through the bores. A washer 40 may be provided and a belleville washer 42 supplements the force exerted between the bolt head 46 on bolt 38 and the sleeve head 48 on sleeve 44 to firmly hold the scalloped bracket members 24 against the radial rim 28. However, since the bore 26, as shown in Fig. 7, is oblong, thermal expansion differences between the material of the annular rotor disk 12 and the hub adapter 14 can be compensated. For instance, the rotor may grow more rapidly than the annular rotor disk, thereby taking up the slack provided by the oblong opening 26. Referring now to the embodiment of Figs. 8 and 9, there is shown an annular rotor disk 110 having parallel, annular, radial friction surfaces 112 and 114. Cooling channels are defined at 116 which extend in a radial plane from the inner circumference to the outer circumference of the annular disk 110. A hub adapter 118 is concentric with the radial, annular rotor disk 110. The hub adapter 118 includes a radial component in the form of lugs 128 extending from the cylindrical, axial ring 119. A plurality of axially extending ribs 120 is provided on the inner surface of ring 119 to engage a hub (not shown) as is known from International Application WO 98/29671.
The rotor disk 110 is provided with circumferentially spaced- apart pairs of inwardly extending lugs 122. Each pair of lugs 122 includes identical lugs 122a and 122b defining a recess 124 therebetween. Axially aligned openings 126a and 126b are provided in lugs 122a and 122b respectively. Each of the openings 126a and 126b has a radially oblong configuration as will be described herein in more detail.
The hub adapter 118 is provided with radially extending, central lugs 128 which are designed to fit in the recesses 124 formed by lugs 122a and 122b in the rotor disk 110. Each lug 128 includes a bore 130 designed to be aligned with openings 126a and 126b when assembled.
Fastener pins or bolts 132, each having a head 134 and a threaded nut 136, are provided for fastening the rotor disk 110 to the hub adapter 118. As shown, the bolt 132 extends through the oblong openings 126a and 126b of lugs 122a and 122b respectively and through the bore 130 of lug 128. The radially oblong configuration of the bores 126a and 126b, as shown in Fig. 8, allows for thermal growth, in the radial direction, of the rotor disk 10 relative to the hub adapter 118. The advantage of the embodiment of Figs. 8 and 9 is that the connection between the hub adapter 118 and the annular rotor disk 110 is symmetrical and, therefore, any distortions created in rotor disk 110 because of heat and/or structural imbalance is reduced during operation.
