Abstract
A disc brake includes a carrier with an inner beam secured to a knuckle, a pair of in board and outboard brake pad assemblies located on opposite sides of a rotor and slideably supported on the carrier, and a caliper extending over the periphery of the rotor and axially moved to urge the in board and outboard brake pad assemblies into frictional engagement with the opposite sides of the rotor. The carrier is constructed so that the difference in natural frequency between a bending mode and a torsion mode is at least 300 Hz. The carrier has a moment of inertia of area/polar moment of inertia of area ratio of at least 0.75.
Claims16
A disc brake, comprising:
- an inboard brake pad assembly and an outboard brake pad assembly each to be located on a respective opposite side of a rotor that has an axis and an outer periphery;
- a caliper to extend over the outer periphery of the rotor and to be movable along the axis thereof, such that said inboard brake pad assembly and said outboard brake pad assembly are each movable into frictional engagement with its respective opposite side of the rotor;
- and
- a carrier slidably supporting said inboard brake pad assembly and said outboard brake pad assembly, wherein said carrier has a first natural frequency in a bending mode and a second natural frequency in a torsion mode and includes an inner beam to be secured to a part of a vehicle and an outer beam connected to said inner beam and spaced therefrom along the axis of the rotor, with said inner beam having a sectional shape such that the difference between the first natural frequency and the second natural frequency is at least 300 Hz.
