Abstract
The invention discloses a double-slip anti-release driving shaft assembly, and mainly solves the problems of inconvenience for installation and easiness in release when a traditional connecting shaft is mounted with a mounting groove of a differential because the traditional connecting shaft is a fixed mounting structure without shrinking. In the double-slip anti-release driving shaft assembly, two ends of an intermediate shaft are respectively connected with a first ball cage and a second ball cage; the second ball cage is provided with a connecting shaft for connecting with the differential; an elastic retainer ring is arranged on the peripheral outer wall of the connecting shaft; and a release preventing mechanism for ejecting or shrinking the elastic retainer ring in the radial direction of the connecting shaft is arranged in the connecting shaft. The release preventing mechanism ejects or shrinks the elastic retainer ring, so that the effects of convenience for assembly, difficult release after assembly in place and convenience for use are achieved.

Accompanying drawing explanation
Fig. 1 is the cross-sectional schematic of one embodiment of the invention.
Fig. 2 is sectional view at the AA of one embodiment of the invention.
Fig. 3 is enlarged drawing at Figure 1A.
Fig. 4 is the schematic diagram of another state of one embodiment of the invention.
Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings: as shown in the figure, double glide separation preventing drive shaft assembly, including jackshaft 3, described jackshaft 3 two ends connect cage 1 and second cage 2 respectively, described second cage 2 is provided with the connecting shaft 15 for being connected with differential mechanism, described connecting shaft 15 peripheral outer wall is provided with circlip 16, is provided with the escapement for backing down or shrink described circlip 16 along described connecting shaft radial direction in described connecting shaft 15.The present invention provides double glide separation preventing drive shaft assembly, its jackshaft two ends connect a cage and the second cage respectively, second cage is provided with the connecting shaft for being connected with differential mechanism, connecting shaft peripheral outer wall is provided with circlip, is provided with for backing down along described connecting shaft radial direction or shrinking the escapement of described circlip in connecting shaft.Backed down or shrink circlip by escapement, easy to assembly, and also assembling is not easy abjection after putting in place, and easy to use.
In the present invention, as shown in the figure, described escapement includes the motion bar 17 along described connecting shaft 15 axially activity being located in described connecting shaft 15, it is provided with support member 4 between described circlip 16 and described motion bar 17, described support member 4 is installed along described connecting shaft 15 radial direction, also include being correspondingly provided with elastic reset part 18 with described motion bar 17, described connecting rod 17 outer wall and described support member 4 are correspondingly provided with chute 171, primary importance that described support member 4 includes described motion bar 17 to fall into when a side shifting bottom chute 171 making described circlip 16 shrink and leave bottom described chute 171 and back down the second position of described circlip 16 under described elastic reset part 18 acts on.The when of motion bar activity to the left, upwards top pressure support member, backs down circlip by support member, prevents abjection；Circlip diameter becomes big；The when that motion bar moving right, support member declines, and circlip shrinks, it is simple to install.
In the present invention, as it can be seen, be additionally provided with spacing back-up ring 19 outside described motion bar 17, described chute 171 inwall is provided with the sliding bevel 172 coordinated with the basal sliding of described support member 4.The when that support member declining, by the sliding bevel being slidably matched, falling the bottom of chute, motion bar is the most movable, and realize pretension by elastic reset part, on the contrary, support member outwards struts circlip when, support member leaves chute, motion bar is moved to the left, spacing back-up ring it is provided with at range, simple in construction, easy to use.
In the present invention, as it can be seen, described support member 4 is installed along described connecting shaft 15 radial direction.Top pressure or shrink time be easier to stress, simple in construction, easy to use.
