Built-in parking locking device of vehicle

Abstract

A built-in parking locking device of vehicle comprises a lock base (2) which is fixed on a box body (12) which supports a transmission rotating shaft (8) and a lock core (6) which is matched on the transmission rotating shaft (8) with a spline and can move axially pulled by a pulling fork (9). The lock base is provided with a lock pin (3); the lock core is provided with a positioning hole (6a) used for circumferential positioning; the rotating shaft passes through the circle center hole of the lock base and is supported on the box body; after the lock core moves towards the lock base direction, the positioning hole (6a) used for the circumferential positioning and the lock pin (3) on the lock base are matched so as to form circumferential fixing; the pulling fork (9) is connected with a gear shifting cam (11).
