Abstract

ABSTRACT OF THE DISCLOSURE
A shield plate is clamped between the spider of an automotive vehicle wheel and the rotor of a disc brake for that wheel. This plate covers the axially inboard side of the wheel spider and prevents dust given off by the disc brake from getting on the wheel at the axially outboard side of the wheel spider, where it would be visible and detract from the vehicle's appearance.

!1 4350-Cont IISHIELD PLATE I~ WHEEL A~D
iDISC BRAKE ASS~MBLY

One of the problçms with disc brakes on cars, part~cu~-arly certain foreign cars, is tha~ during ~raking a su~seantial amount of dus~ is given off by the brakes and ends up on the axially outboard side of the wheels, leaving a coating which de-10tract~ from the car's appearance.
The presen~ 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 bra~e from reaching the l visible side o the wheel.
In accordance with a presently-preferred embodiment of ~he invention, a generally f~at shield plate i6 sandwiched between the brake rotor and the spider of the wheel at the axially inboar~
side of the spider. This shield plate ~s spaced axially outward from the brake disc, and it covers the inside of the wheel at the inboard side of the whee~ spider so as ~o prevent dust given off by the braking rom reaching the wheel on th~ outboard side of the wheel ~p~der.
A principal object of this invention is to provide an l improved Yehicle wheel and disc ~rake assembly having a novel shield arrangement for preventing dust produced by the brake from Illbei~, deposited o~ a vi~ible por~ion o~ ~hc wh~el.

~ r ~ ~ ~ ~
~_ _ _ _ 18~3~

In one aspect of the invention there is provided a vehicle wheel having an annular tire support and a spider extending inward from the rim transverse to the axis of the wheel, said spider having a plurality of openings therein spaced inward from the rim, and a disc brAke having a caliper with a brake pad, and a brake rotor clamped to the wheel spider and carrying a brake disc spaced axially inboard from the wheel spider and facing the spider, said brake disc producing braking dust at the side thereof facing said spider due to friction generated between said brake pad and said brake disc when the brakes are applied, the improvement which comprises a shield plate clamped between the wheel spider and the brake caliper and the brake rotor axially outboard from the brake caliper and the brake disc, said shield plate blocking the axially inboard side of the wheel spider from the brake caliper to prevent the escape of friction generated braking dust from the brakes through the wheel spider onto the wheel at the axially outboard side o~ the wheel spider.

-la-8~11 Further objects and advan-ages of this invention will be apparent from the following Idetailed description of two presently-preferred embodiments thereof, which are shown in the accom~anying drawing.
- ¦ DESCRIPTION OF T~E DRAWING
Figure 1 is a perspective view of a shield pla~e in accordance with the present invention;
Figure 2 is an ou~er end view o a wheel and disc brake S assembly incorpora~ing the present shield plate;
- Figure 3 is a longi~udinal section ~hrough this asse~bly taken along the line 3--3 ir. Figure 2; and Figure 4 is a fragmentary longi~udinal section showing a modified arrangemen~ of the ~heel, ~isc brake and shield plate o i! assembly of this invention.

! Be~o~e explaining in detail the illustrated embodiments I o the invention, it is to be understood hat the invention is not limited to the details o~ the par.icular arrangements shown but is capable of other emb~diments. Also, the termino~ogy used herein is for the purpose of description and not of limitation.
DETAI~ED D~SCRIPTIO~
l Refe~ing to Fig~e 3, the present assembly includes a ! car wheel and a disc brake of conven~ional design. The righ~ s.de ¦¦is the axially outboard, visible side of the whee~ in Figure 3.
IIThe wheel has an annular rim 10 which carries a~ inflatable tire ¦I(not shown) a~d a spider 11 rigidly a..ached to the inside of the rim and extending ~ransversely inward from it i~ a generally li .
- 2 -' ` ' 11i~1801 radial direc~ion. The wheel spi~er has a central 022ning 12 which extends in spaced relation around the hub 13 of the brake rotor 14. The wheel spider also is o -,ed wiLh a plurality of circu~ferentially spaced, arcuate openlngs lla (Figure 2) for design and strength purposes.
At the axially outboard (right) side of the wheel s~ider 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 ro~or is ro~ata~ly mounted by anti-riction bearings.
At the axially inboard (left) side o~ the wheel spider ll in ~Figure 3 ~he ~rake rotor 14 ?resents a cylindrical side wall 16 1f substan~ially larger diameter than the central opening 12 in the spider 11 of ~he wheel. This cylindrical side wall 15 i6 .
joined integrally to the hub 13 of the brake rotor by a flat, annular, transverse wall 17 extending radially between 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 correspond-ing openings 19 in the wheel spider 11. ~uts 20 are threaded onto t~e wheel studs 18 to clamp ~he brake rotor L4 to the wheel.
A brake disc 21 is af~ixed to a sligh~ly enlarged seg-ment 22 of the brake rotor 14 at the axislLy in~oard end of its cylindrical side wall 16. A disc bra~e caliper 23 carries frictional wear pads for engagement with the brake disc 21 in a known manner. The brake caliper is suitably mounted on t~e vehicle so as to remai~ Stationary while the wheel 10, ll, the l 11'~1 8Vl brake ro~or 14 and ~rake disc 21 roLate in unison.
¦ In accordance with the p.esent invention, an annular shield pla.e 24 as shown in Figu.e 1 is clam?ed between the wheel spider ll and the transverse wall ~7 o~ the brake rotor. In the embodiment shown in Figure l 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 llb OL the wheel s?ider ll where the I latter is ioined to the wheel rim ~0. The shield ?late 24 is l formed with a plurality of openings 26 whlch regis.er wi.h the l openings 19 in the wheel spider 11 ~o. passing the wheel studs 18 llon the bra~e rotor. Also, the shield plaLe 24 has a circular ¦¦central opening 27 which passes the hub 13 of the brake rotor.
j! As shown in Figure 3, the shield plate 24 extends com-1! pletely across ~he axially inboard ,ace OL the wheel spider 11 ! where the latter would o~herwise be ex2osed to dust produced by the disc bral~e when it is appliedO The shield plate prevents such dust ~rom escaping through the openings lla in the wheel spider l and lodging on the wheel at the axially outboard side of the 2~ wheel spider. There is only very sligh~ clearance or no clearance betweenthe outer edge 25 of this plate and the inside of the wheel ~so that virtually no dirt or wa~er can escape sxially outboard past the shield plate.
¦ In ~he modified a~angement shown ~n Figure 4, plate 24 !lis formed with an axially o~set bulge 24' to accor~nodate a bra'~e ~caliper 23~ which extends axially ~utboard beyond the transverse . i ` ~ 8~1 wall 17 of the brake rotor 17. Except for this change, the assembly is the same as in Figure 2, w~th the shield plate being of thin, flat configura~ion except a~ the bulge 24' and the o~'r.er elements of the assembly being identical to the corresponding elements in Figure 3. ~ .
