  • Publication number: 20240101093
    Abstract: A vehicle brake system includes a switching valve switchable between a first state allowing communication between a first fluid pressure generating device and a frictional brake and a second state allowing communication between a second fluid pressure generating device and the frictional brake. The second fluid pressure generating device generates a fluid pressure by moving a piston with an electric actuator, and has a fluid pressure supply port connected to the switching valve and an atmosphere opening port connected to a reservoir tank. When, due to a failure, the switching valve becomes a third state in which the switching valve makes each of the first fluid pressure generating device and the second fluid pressure generating device communicate with the frictional brake, a control device controls the second fluid pressure generating device to close the atmosphere opening port with the piston.

  • Publication number: 20240075915
    Abstract: A vehicle brake system includes a first fluid pressure generating device for generating a fluid pressure according to a brake operating amount, a second fluid pressure generating device for generating a fluid pressure by moving a piston with an electric actuator, and a switching valve switchable between a first state allowing communication between the first fluid pressure generating device and a vehicle behavior stabilizing device and a second state allowing communication between the second fluid pressure generating device and the vehicle behavior stabilizing device. A control device places the switching valve in the second state during execution of automatic brake control, and places the switching valve in the first state when a predetermined abnormality occurs in the vehicle, except that the control device places the switching valve in the second state when an abnormality including inability of the second fluid pressure generating device to generate the fluid pressure occurs.

  • Publication number: 20220121000
    Abstract: Provided is a lens barrel capable of improving stop accuracy. A roller support shaft (61) is attached to an outer peripheral portion of a cam cylinder (16). A torque applying roller (102) is rotatably supported by the roller support shaft (61). A biasing ring (104) is fitted to an outer peripheral portion of a second fixed cylinder (12B) and is held to be movable in an axial direction. The biasing ring (104) is biased by a biasing spring (106) and pressed to abut against the torque applying roller (102). In a case where the cam cylinder (16) is rotated, the torque applying roller (102) rolls along the biasing ring (104). A load torque is applied to the rotation of the cam cylinder (16) by frictional force generated between the torque applying roller (102) and the roller support shaft (61) due to the rotation of the torque applying roller (102).
