Abstract
A piston assembly is disclosed herein. The piston assembly includes a piston having a first end, an opposing second end, and a sidewall extending from the first end to the second end, the piston further including a cavity at least partially defined by the sidewall, a spring guide having a first end and an opposing second end, the spring guide disposed within the cavity of the piston and adjacent the sidewall, an insulator having a first portion extending from the second end of the piston and a second portion disposed within the piston, an insulator shield disposed adjacent the first portion of the insulator, and a component coupled to the second end of the spring guide, the component being offset from the insulator shield by a distance.

A piston assembly, comprising:
- a piston having a first end, an opposing second end, and a sidewall extending from the first end to the second end, the piston further including a cavity at least partially defined by the sidewall;
- a spring guide having a first end and an opposing second end, the spring guide disposed within the cavity of the piston and adjacent the sidewall;
- an insulator having a first portion extending from the second end of the piston and a second portion disposed within the piston;
- an insulator shield disposed adjacent the first portion of the insulator;
- and
- a component coupled to, surrounding, and enclosing the second end of the spring guide between the spring guide and the insulator shield, the component being offset from the insulator shield by a distance thereby forming an airgap between the component and the insulator shield.
A brake assembly, comprising:
- a plurality of stator disks;
- a plurality of rotor disks interleaved with the plurality of stator disks;
- a pressure plate disposed adjacent one of the plurality of rotor disks;
- and
- a piston assembly disposed adjacent the pressure plate, the piston assembly including:
- a piston having a first end, an opposing second end, and a sidewall extending from the first end to the second end, the sidewall at least partially defining a cavity;
- a spring guide having a first end and an opposing second end, the spring guide disposed within the cavity of the piston and adjacent the sidewall;
- an insulator having a first portion extending from the second end of the piston and a second portion disposed within the piston;
- an insulator shield disposed adjacent the first portion of the insulator adjacent the pressure plate;
- and
- a component coupled to, surrounding, and enclosing the second end of the spring guide between the spring guide and the insulator shield, the component being spaced from the insulator shield by a distance thereby forming an airgap between the component and the insulator shield.
A piston assembly, comprising:
- a hollow cylindrical piston having a first end and an opposing second end;
- a spring guide having a first end and an opposing second end disposed within the hollow cylindrical piston;
- a component coupled to, surrounding, and enclosing the second end of the spring guide;
- an insulator coupled to the second end of the hollow cylindrical piston, the insulator offset from the component by a first distance;
- and
- an insulator shield coupled to the insulator and offset from the component by a second distance thereby forming an airgap between the component and the insulator shield, wherein the component is disposed between the spring guide and the insulator shield.
