In order to keep the force value curve of the damping force the same as the pedal force, a cylindrical compression spring 24 is used, which is capable of generating a linear force value.
In order to ensure the increasing linearity of the damping force and avoid the sharp increase imagination, the rotating boss gradient is designed as follows:
assuming that the pedal stroke angle is α, the sensor rotation angle is β, and the second damper blade rotates in synchronization with the sensor shaft, the rotation angle of the second damper blade is the same as the sensor rotation angle.
According to the utility model discloses an accelerator pedal's structural feature establishes the utility model discloses accelerator pedal's connecting rod revolution mechanic, as shown in fig. 12, then footboard stroke angle α is as follows with the relational expression that the sensor rotation angle is β:
α′＝(180°-γ)
g＝c×sinα′＝c×sin(180°-γ)
f＝a×sin(α-α′)＝a×sin(α-(180°-γ))
β′＝90°-(α-α′)＝90°-(α-(180°-γ))
g+f＝b×cos(β-β′)

c×sin(180-γ)+α×sin(α-(180°-γ))＝b×cos(β-(90°-(α-(180°-γ))))
The relationship between the rotation angle of the damper 2 and the rotation angle of the pedal is calculated as follows:
β＝270°-α-γ+arccos((α×sin(α+β-180°)+c×sin(180°-γ))/b)
