Abstract
A brake assembly includes a rotor and at least one backplate supporting a brake pad for frictionally engaging the rotor for braking. A sheet metal plate is operatively connected to the back plate. The sheet metal plate has a groove cut therethrough to form at least one tuning fork member. A damping material is engaged with the at least one tuning fork member for damping energy associated with vibrations of the tuning fork member, thereby sound-dampening brake squeal noise.
Claims16
A brake assembly comprising:
- a rotor;
- a brake pad positioned for selective engagement with the rotor for braking;
- a sound damping member operatively connected to the brake pad, said sound damping member having a groove cut therethrough to form at least one tuning fork member, and having a damping material engaged with said at least one tuning fork member for damping energy associated with vibrations of the tuning fork member, thereby sound-dampening brake squeal noise, wherein said groove forms a generally sine-wave shape in the sound damping member.
A brake assembly comprising:
- a braking component operative to apply a braking force to a vehicle wheel, said braking component being subject to vibration during braking;
- a sheet metal plate operatively connected to the braking component, said sheet metal plate having a groove cut therethrough to form at least one tuning fork member, wherein each said tuning fork member is at least approximately three time as long as it is wide;
- and
- a damping material engaged with said at least one tuning fork member for damping energy associated with vibrations of the tuning fork member, thereby sound-dampening brake squeal noise.
