Definitions

• This invention relates to the protection of wheels of a vehicle from dust given off by the brakes of the vehicle.
• the present invention is directed to a wheel and disc brake assembly which incorporates in a novel manner a shield plate which prevents dust given off by the brake from reaching the visible side of the wheel.
• a generally flat shield plate is sand- wiched between the brake rotor and the spider of the wheel at the axially inboard side of the spider.
• This shield plate is spaced axially outward from the brake disc, and it covers the inside of the wheel at the inboard side of the wheel spider so as to prevent dust given off by the braking from reaching the wheel on the outboard side of the wheel spider.
• a principal object of this invention is to provide an improved vehicle wheel and disc brake assembly having a novel shield arrangement for preventing dust produced by the brake from being deposited on a visible portion of the wheel.
• Figure 1 is a perspective view of a shield plate in accordance with the present invention.
• Figure 2 is an outer end view of a wheel and disc brake assembly incorporating the present shield plate
• Figure 3 is a longitudinal section through this assem ⁇ bly taken along the line 3—3 in Figure 2; and Figure 4 is a fragmentary longitudinal section show ⁇ ing a modified arrangement of the wheel, disc brake and shield plate assembly of this invention.
• the present assembly includes a car wheel and a disc brake of conventional design.
• the right side is the axially outboard, visible side of the wheel in Figure 3.
• the wheel has an annular rim 10 which carries an inflatable tire (not shown) and a spider 11 rigidly attached to the inside of the rim and extending transversely inward from it in a generally radial direction,
• the wheel spider has a central opening 12 which extends in spaced relation around the hub 13 of the brake rotor 14.
• the wheel spider also is formed with a plurality of cir- cumferentially spaced, arcuate openings 11a ( Figure 2) for design and strength purposes.
• the brake rotor At the axially outboard (right) side of the wheel spider 11 in Figure 3 the brake rotor carries a cap 15 which covers the end of the stub shaft (not shown) of the steering knuckle on which the brake rotor is rotatably mounted by anti-friction bearings.
• the brake rotor 14 presents a cylindrical side wall 16 of substan ⁇ tially larger diameter than the central opening 12 in the spider 11 of the wheel. This cylindrical side wall 16 is joined integrally to the hub 13 of the brake rotor by a flat, annular, transverse wall 17 extending radially be ⁇ tween them.
• a plurality of circumferentially spaced, screw- threaded wheel studs 18 extend axially outward from the transverse wall 17 of the brake rotor. These studs pass loosely through corresponding openings 19 in the wheel spider 11. Nuts 20 are threaded onto the wheel studs 18 to clamp the brake rotor 14 to the wheel.
• a brake disc 21 is affixed to a slightly enlarged segment 22 of the brake rotor 14 at the axially inboard end of its cylindrical side wall 16.
• a disc brake cali- per 23 carries frictional wear pads for engagement with the brake disc 21 in a known manner.
• the brake caliper is suitably mounted on the vehicle so as to remain station ⁇ ary while the wheel 10, 11, the brake rotor 14 and brake disc 21 rotate in unison.
• an ' annular shield plate 24 as shown in Figure 1 is clamped between the wheel spider 11 and the transverse wall 17 of the brake rotor.
• the shield plate is thin and flat.
• This shield plate has a circular outer periphery 25 which, as shown in Figure 3, has a slight clearance from the inside of the cylindrical outer periphery lib of the wheel spider 11 where the latter is joined to the wheel rim 10.
• the shield plate 24 is formed with a plurality of openings 26 which register with the openings 19 in the wheel spider 11 for passing the wheel studs 18 on the brake rotor.
• the shield plate 24 has a circular central opening 27 which passes the hub 13 of the brake rotor.
• the shield plate 24 extends com ⁇ pletely across the axially inboard face of the wheel spi- der 11 where the latter would otherwise be exposed to dust produced by the disc brake when it is applied.
• the shield plate prevents such dust from escaping through the openings 11a in the wheel spider and lodging on the wheel at the axially outboard side of the wheel spider. There is only very slight clearance or no clearance between the outer edge 25 of this plate and the inside of the wheel so that virtually no dirt or water can escape axially outboard past the shield plate.
• plate 24 is formed with an axially offset bulge 24' to accom ⁇ modate a brake caliper 23' which extends axially outboard beyond the transverse wall 17 of the brake rotor 17.
• the assembly is the same as in Fig. 2, with the shield plate being of thin, flat configura- tion except at the bulge 24 ' and the other elements of the assembly being identical to the corresponding elements in Figure 3.
