Problems solved by technology

[0002] Existing transmissions usually use a locking member to cooperate with the locking groove to achieve axial locking of the shift fork shaft. This structure makes the locking stability of the shift fork shaft weak when the gearbox is in neutral, and gear jumps are prone to occur. question

Embodiment Construction

[0019]As shown, the shifting locking device including the fork shaft 1 and the main locking member 2 and auxiliary locking member 3 for axial axial locking of the fork axis, the main locking member A jointly blending with the auxiliary locking unit allows the main locking member to simultaneously drive the auxiliary locking member during unlocking assembly to unlock the auxiliary lock unit synchronously. Combinefigure 1As shown, the fork shaft can be axially slid on the casing, and the fork axis can be locked by the main locking member 2 and the auxiliary locking member 3, so that the shifting fork is in a certain gear position, The bit is highly stable and can ensure that the neutral does not jump; when the external vehicle exceeds the driving force of the fork axis, the main lock unit unlocks and synchronizes the secondary lock file unlock, two lock gear unlocked Linked, facilitating the axial driving force required for the fork axis when the unlock is increased, and the auxiliary...

Abstract

The invention discloses a gear shifting locking device. The device comprises a shifting fork shaft, a main gear locking piece and an auxiliary gear locking piece, the main gear locking piece and the auxiliary gear locking piece are used for axially locking the shifting fork shaft, and the main gear locking piece and the auxiliary gear locking piece are in linkage fit so that the main gear locking piece can synchronously drive the auxiliary gear locking piece in the shifting fork shaft unlocking process so that the auxiliary gear locking piece can be synchronously unlocked. The shifting fork shaft can be locked through the main gear locking piece and the auxiliary gear locking piece, so that the gear shifting fork stays at a certain gear position, the gear locking stability is high, and it can be guaranteed that gear skipping does not occur in the neutral position; when the external driving force on the shifting fork shaft exceeds a specific value, the main gear locking piece is unlocked, the auxiliary gear locking piece is synchronously driven to be unlocked, the two gear locking pieces are unlocked in a linkage mode, the axial driving force needed by the shifting fork shaft during unlocking is increased, the auxiliary gear locking piece does not depend on the axial pushing force of the shifting fork shaft during unlocking, and the matching relation between the auxiliary gear locking piece and the shifting fork shaft is simplified.

Description

Technical field[0001]The present invention relates to the field of transmission, and more particularly to a shifting locking device.Background technique[0002]The existing transmission is typically in which the locking lock of the finger is locked by a locking member, which makes the gearbox in the neutral state, and the locking stability of the fork axis is weak, and it is easy to have a jumping gear. problem.[0003]Based on the above problems, there is a need for a shift locking device that achieves the locking unit through the active lock member and the auxiliary locking member, improves the lockor stability and reliability, ensuring that the neutral will not jump.Inventive content[0004]In view of this, the present invention provides a shift locking device that enables locking files to enhance the locking of the lock, and ensure that the neutral gear is not jumping gear by an active lock member and auxiliary locking member.[0005]The shift locking device of the present invention inc...
