SHOCK ABSORBING DEVICE FOR FORWARD REVERSE SHIFTING LEVER FOR MICROSHOVEL CAR

摘要

PURPOSE:To improve an operation feeling through absorption of a shock during engagement of a claw clutch by mounting a servoclutch between the claw clutch of a forward reverse shifting shaft and the worm gear of a shaft end part, so that transmission of a power is delayed. CONSTITUTION:When a drive force is transmitted to a forward reverse shifting lever 36 through a claw clutch 37, a clutch disc 43 on the drive side is rotated. Through energization of a slide plate 46 through the force of a spring 47, the clutch disc 43 on the drive side and a clutch disc 42 on the driven side are brought into contact with each other, and a multidisc clutch 44 is brought into a half-clutch state. In this case, a ball 54 presses a cam plate 48 against the multidisc clutch 44 side through the force of a spring 51 of a clutch bracket 40. Thus, a cam plate 48 causes gradual pressure contact of the multidisc 44 against the force of the spring 47, and when the slide plate 46 is brought into contact with a stopper plate 45, the multidisc clutch 44 is forced into an adhesion state, the forward reverse shifting shaft 36 and the clutch bracket 40 are brought into a coincidental rotation state, and a worm gear G6 is also integrally rotated. This constitution prevents the generation of a shock during engagement of a claw clutch.
