20230415712 · 2023-12-28 · ·

Embodiments herein are directed to an emulator assembly. The assembly includes a housing with a cavity, a pedal arm, an elongated member, a carrier, an end plate and a compressible member. The pedal arm is at least partially received in the cavity and has a pedal pad on one end. The elongated member extends and couples to the pedal arm on one end and couples to a carrier on an opposite other end. The end plate is spaced apart from the carrier. The compressible member is positioned in the space between the carrier and the end plate. When the pedal pad is depressed, the elongated member moves the carrier in a direction towards the end plate which drives the carrier into the compressible member such that the compressible material compresses to generate a force feedback onto a foot positioned on the pedal pad.
