Embodiment Construction

[0026] In order to further explain the technical means and functions adopted by the present invention to achieve the intended purpose of the invention, the specific embodiments, structures, features and functions of the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0027] Please refer to figure 2 and Figure 7-11 , A vehicle parking lock device according to an embodiment of the present invention includes a parking ratchet 1 , a parking pawl 2 and an actuating mechanism 3 . The parking ratchet 1 can be installed on the output shaft of the transmission or the differential by means of one-piece, spline connection or bolt connection. Parking pawl 2 is installed on the pawl rotating shaft 4, and can rotate around it. The actuating mechanism 3 is used to drive the parking pawl 2 to move around the pawl rotation axis 4 between a locked position and an unlocked position.

[0028] The parking ratchet 1...

Abstract

A vehicle parking locking device comprises a parking ratchet wheel, a parking detent and an actuating mechanism, the actuating mechanism comprises a pressing head used for driving the parking detent to move between a locking position and an unlocking position in a switched mode, the parking detent comprises a first end and a second end opposite to the first end, and the first end is close to the parking ratchet wheel; the pressing head comprises a supporting frame, a containing space is formed inside the supporting frame, the first end on the back of the parking detent extends outwards to form a locating piece in the length extending direction of the parking detent, the locating piece is contained in the containing space when the parking detent is located in the locking position, and the locating piece penetrates out of the containing space and stopped by the supporting frame when the parking detent is located at the unlocking position. When the parking detent in the vehicle parking locking device is located at the unlocking device, the locating piece on the parking detent can be stopped by the supporting frame, the range in which the parking detent moves downwards due to shake is limited, the parking detent is prevented from being meshed with the parking ratchet wheel, and therefore it is guaranteed that mistaken gear shifting of the parking detent cannot occur.

Description

technical field [0001] The invention relates to the technical field of automobiles, and in particular to a vehicle parking locking device. Background technique [0002] Cars equipped with automatic transmissions need to be equipped with a vehicle parking lock device on the transmission in order to prevent the wheels from turning when parking, so as to achieve the purpose of locking the transmission and thus locking the entire vehicle. Most of the existing vehicle parking lock devices realize the parking lock through the engagement of the parking pawl and the parking ratchet. [0003] Chinese utility model patent CN2856600Y records a kind of automobile locking device, as figure 1 As shown, it includes a parking pawl installation shaft 201 , a parking pawl 207 , a cam mechanism 203 , a cam installation shaft 204 , a cam limit mechanism 205 , a pawl return mechanism 206 and a parking ratchet 208 . Wherein the parking pawl 207 is rotatably installed on the parking pawl install...
