Title: Runaway preventing device for actuator
Inventor: TAKAHASHI HISAYUKI
IPC: B62D7/14
Filed: 1988-12-28
Abstract: PURPOSE:To obtain a runaway preventing device for an actuator by providing a nonreturn valve adapted to open in association with the inward movement of a pair of lock rods connected to the end portion of an expansion link mechanism on each end chamber side of an actuator in an actuator for steering the rear wheels of a four wheel steering vehicle. CONSTITUTION:When a hydraulic defect is caused to release oil pressure in pipes 27, 27a, the left nonreturn valve 6 is closed, and the right nonreturn valve 6a is pushed to open by a lock rod 16a. Even if external force for pushing a piston 21 to the left is applied, the piston 21 is checked from moving to the left because oil in an end chamber 22 is closely sealed in by the nonreturn valve 6. On the other hand, a link mechanism A is expanded in a straight line, and the right lock rod 16a is pushed to the right to collide with a contacting piece 17a, so that the rod 23 is pushed back to the right. Oil in the end chamber 22a is discharged to the outside through the nonreturn valve 6a and a pipe 27a, so that the end chamber 22 becomes negative pressure. When the link mechanism A is expanded in a straight line, both side lock rods 16, 16a collide with contacting pieces 17, 17a of a rod 23 so that an actuator 26 is kept in the neutral position.
