Abstract
A heat shield particularly adapted for use with a wheel surrounded multiple disc brake wherein the wheel is provided with a plurality of circumferentially spaced apart fixed drive keys extending into drivable engagement with a plurality of brake rotor discs. The heat shield is defined by spaced apart wall portions fixedly secured together to form a rigid structure permitting air flow between the wall portions thereof. The heat shield is removably secured in position between adjacent drive keys and in radially spaced apart relationship to the tire supporting rim portion of the wheel to thereby resist heat transfer radially outwardly from the brake to the rim portion and retain heated brake debris discharged radially outwardly by the rotor discs.
Claims10
A wheel and heat shield therefor comprising in combination:
- a tire supporting wheel rim defining a brake cavity adapted to receive a brake assembly having rotatable and non-rotatable frictionally engageable members;
- a plurality of elongated drive key means fixedly secured to said wheel rim in circumferentially spaced apart formation and extending radially inwardly therefrom into engagement with said rotatable member;
- a plurality of heat shields removably secured in position between said plurality of drive key means to define a substantially continuous annular wall having a radially spaced relationship to said wheel rim;
- each of said heat shields including first and second spaced apart plate members fixedly secured together to define a rigid double wall structure having an air space therebetween and opposite side portions engaged with adjacent drive key means for supporting the heat shield in spaced apart relationship with said wheel rim;
- and
- fastening means including a spacing member operatively connected to said heat shield and said wheel rim for reinforcing said radially spaced relationship therebetween and fixedly securing said heat shield in position between said adjacent drive key means.
