Definitions

  • a vertical, longitudinal, and lateral directions are based on the orientation of the clutch operation effort reactive force generator installed in a vehicle, such as an automobile.
  • the vertical, longitudinal, and lateral directions will also be referred to as a height-wise direction, a front-back direction, and a width-wise direction, respectively.
  • the actuator operates or drives the clutch device as a function of the position of the clutch pedal 4 depressed by the driver of the vehicle 1.
  • the clutch pedal 4 is mechanically connected to the clutch device.
  • the supporting member 10 includes the front bottom wall 10A, the front left side wall 10B, the front right side wall 10C, the rear left side wall 10D, and the rear right side wall 10E.
  • the front bottom wall 10A extends in the longitudinal direction of the vehicle 1.
  • the front left side wall 10B extends upward from a left end of front bottom wall 10A.
  • the front right wall 10C extends upward from a right end of the front bottom wall 10A.
  • the rear left side wall 10D extends rearward from a rear end of the front left side wall 10B.
  • the rear eight side wall 10E extends rearward from a rear end of the front right side wall 10C.
  • the rear surface 10r of the panel attachment 10F is, as clearly illustrated in Fig. 1 , placed in direct contact with the front surface 2f of the dashboard panel 2.
  • the rear surface 10r is firmly fastened to the dashboard panel 2 using a plurality of bolts 6 (only one is shown in Fig. 2 ), thereby securing the supporting member 10 to the dashboard panel 2.
  • the supporting member 10 as can be seen in Figs. 2 and 3 , has the upper wall 10G.
  • the upper wall 10G connects between upper ends of the front left side wall 10B and the front right side wall 10C and extends substantially vertical at an inclined angle relative to the direction A in which the cam plate 13, which will be described later in detail, is moved.
  • the cam plate 13a has the joint groove 13a formed therein.
  • the joint groove 13a has a font end of the rod 14 joined thereto.
  • the pedal bracket 3 is, as can be seen in Fig. 1 , equipped with the rod support 3A to which the rear end of the rod 14 is joined.
  • the cam plate 13 has the cam face 13A formed on an upper surface thereof.
  • the roller 16B is placed in contact with the cam face 13A.
  • the friction member 19 is inclined relative to the direction in which the cam plate 13 moves. Specifically, the friction member 19 is obliquely oriented to have the upper end 19b facing the cam plate 13 in the direction A of movement of the cam plate 13 and the lower end 19c facing away from the cam plate 13 in the direction A of movement of the cam plate 13.
  • the friction member 19 is held from moving in a direction of inclination of the upper wall 10G.
  • the friction member 19 frictionally contacts the cam follower 16.
  • the friction member 19 will also be referred to below as a second friction member.
  • the clutch operation effort reactive force generator 5 in this embodiment has the cam face 13A shaped to have the convex cam face 13c which extends from the front end 13f of the cam plate 13 facing the cam follower 16 toward the rear end 13r and protrudes gradually in a direction perpendicular to the direction A of movement of the cam plate 13.
  • the clutch operation effort reactive force generator 5 works to produce the reactive force which gradually increases in the early half or first half (i.e., W1 in Fig. 5 ) from start of depression of the clutch pedal 4 to approximately half of the total amount by which the clutch pedal 4 is depressed (i.e., total amount of stroke of the clutch pedal 4), and also produce the reactive force which gradually decreases in the last half or second half (i.e., W2 to W3 in Fig. 5 ) of the depression of the clutch pedal 4.
