HYSTERESIS CHARACTERIZING TYPED ELECTRO PEDAL DEVICE
First Claim
1. A hysteresis characterizing typed electro pedal device comprising:
- a pedal that is hinged at one end by a pedal member to be stamped by a driver; and
a pedal simulator that changes a damping force by operation and return stroke of the pedal by allowing oil filled in a chamber to flow backward through a piston flange formed at one end of a piston connected to the pedal when the piston is pushed in the chamber of a housing by operation of the pedal, and by discharging the oil through the piston flange when the piston is pushed out of the chamber of the housing by return of the pedal and discharging the oil through a gap between a cup that is compressed by oil pressure and the inside of the chamber.

Abstract
According to the electro pedal of the present invention, a pedal simulator is achieved by a variable damper including a piston operating with an operation rod connected to a pedal and elastically supported by first and second springs having different elasticity, a piston flange having a flow channel, through which the oil passes, at the end of piston elastically supported by second spring in a chamber filled with the oil, and a rubber cup being in close contact with piston flange and changing the flow rate of oil while being elastically deformed by the hydraulic pressure according to the flow direction of the oil, such that hysteresis characteristics showing pedal effort without difference can be achieved, such as when hydraulic pressure is used, not only generating simple linear pedal effort and a damping force from a fixed damping coefficient in operation and return stroke of pedal.
