That there are assembly times is long for this mode, under the conditions of transmission shaft periphery operating space is limited on special vehicle, passes
Moving axis flange bolt dress is torn open highly difficult, and assembling quality is not easy to ensure.When especially dismantling when transmission shaft, need to remove week in advance
The structure of many complexity on side, causes the maintainability of vehicle very poor.
In addition, often because general layout needs to make drive assembly arrangement at a distance of relatively close on special vehicle, in this way due to by
The limitation of flange attachment bolt, universal drive shaft can not use because of installation space deficiency, can only use and not too much adapt to automobile
Other non-Universal drive shaft couplings of work characteristics, affect the reliability of transmission system.

Equipped with the second wedge slot；Retaining mechanism, the embedded first wedge slot and the second wedge slot, to link the transmission shaft flange and institute
State assembly flange；Hold-down mechanism wraps the retaining mechanism, and to clamp the retaining mechanism, the retaining mechanism is pressed on
On the assembly flange and transmission shaft flange.
Further, the first wedge slot and the second wedge slot are ring wedge slot.
Further, the retaining mechanism includes lock ring, the embedded first wedge slot and the second wedge slot.
Further, the first lock tooth and the second lock tooth are provided on the lock ring, the first lock dental inlay enters described first
Wedge slot, the second lock dental inlay enter the second wedge slot.
Further, the first lock tooth and the second lock tooth are ring lock tooth.
Further, the hold-down mechanism includes clip, wraps the retaining mechanism.
Further, the both ends of the clip offer corresponding bolt hole.
Further, the both sides of the clip are at U-shaped.
In the outer circle of the retaining mechanism insertion transmission shaft flange of lock ring locking type propeller shaft couplings device provided by the invention
First wedge slot and assembly flange excircle on the second wedge slot, hold-down mechanism clamp retaining mechanism, retaining mechanism is pressed on always
Simple on flange and transmission shaft flange, filling, tearing open, assembling quality can ensure, maintainability is good, not influence the reliable of transmission system
Property, propeller shaft couplings efficiency is improved, assembly labor intensity is reduced.
