Abstract

Resin-based electronic parking brake pistons, methods of making said pistons, and methods of using said pistons are disclosed, wherein each piston has a piston body made of a sole synthetic polymer material consisting of at least one reaction product obtained by reacting at least one formaldehyde with at least one phenol and/or at least one substituted phenol. Each piston may also have an internal contact area disposed in an interior of the piston body and configured to contact at least one spindle nut of at least one electromechanical parking brake system and/or an outer surface disposed on an exterior of the piston body and configured to be slidable within at least one caliper bore of at least one electromechanical parking brake system.

Abstract

A low cost, low volume, electrical discharge texturing machine which can texture rolling mill rolls having a broad range of diameters and lengths either on a production or research and development basis. The machine is relatively portable, for example, it can be mounted on a skid or a palate, and can be used at any location having an adequate electrical supply. Electrodes are mounted on the machine in a manner which maximizes flexibility in respect of the roll diameters that can be textured. The machine also has adjustable supports for the rolls and a dielectric oil tank to provide additional flexibility in the roll dimensions that can be textured. Furthermore, the machine has programmable x-axis drives and these can optionally be used in combination with programmable roll drives.

The machine is relatively portable, for example, it can be mounted on a palate, and can be used at any location having an adequate electrical supply. Electrodes are mounted on the machine in a manner which maximizes flexibility in respect of the roll diameters that can be textured. The machine also has adjustable supports for the work rolls which can raise or lower a roll surface relative to the electrodes to provide additional flexibility in the roll dimensions that can be textured. Furthermore, the machine has programmable x-axis drives and these can optionally be used in combination with programmable roll drives.
