A disc brake comprises at least two axially slidable brake discs. The brake discs are mounted for axial sliding movement under the dynamic conditions of use by means of a series of circumferentially spaced wire springs or leaf springs each of which simultaneously receives the at least two brake discs on the axially-extending structure of the spring. As a result, initiation of braking causes simultaneous axial sliding movement of the entire spring and multiple disc assembly as a unit, thereby achieving a more balanced braking action and more even friction pad wear.

Method and apparatus for constructing disc brakes

A disc brake system of the kind comprising an axially fixed hub and at least one slideable brake disc comprises a resilient device acting between the disc and the hub to control certain aspects of the movement of the brake disc during use. Despite the thermal differential arising in use between the brake disc and the central hub due to the localized heat generation of the brake system and the mass and thermal capacity differences between the hub and the brake disc, whereby the hub would be expected to provide a more satisfactory mounting, the resilient device acting between the disc and the hub to control the disc dynamics is mounted on the disc.

Method and apparatus for mounting a brake disc with resilient biasing means

A disc brake ( ) of the kind comprising an axially fixed hub ( ) and at least one slidable brake disc ( ) comprises resilient means ( ) acting between the disc ( ) and the hub ( ) to control certain aspects of the movement of the brake disc ( ) during use. The resilient means ( ), is of a leaf spring format, acting between the disc ( ) and the hub to control the disc dynamics is mounted on the disc ( ). This leads to advantages in terms of spring structure and cost and independence of the resilient bias with respect to disc position and disc ( ) relationship to another disc (if present) and with respect to simplicity of mounting and avoidance of dirt entrapment. The mounting of the resilient means comprising clipping the resilient means over a drive key ( ) of the disc ( ) though an aperture ( ) defined within the resilient means ( ) and having associated stiffening elements or strips ( ). The resilient means ( ) accordingly being securely and captively attached and located relative to the disc ( ) and the resilient means ( ) providing a resilient bias force directed through the drive key ( ).
