Abstract
The invention discloses an interlocking mechanism of main and auxiliary boxes of a combined transmission. The interlocking mechanism comprises a main box shifting fork shaft, an auxiliary box shifting fork shaft and an interlocking pin, wherein the rear end of the main box shifting fork shaft and the front end of the auxiliary box shifting fork shaft are supported into two shifting fork shaft holes in a rear barrier wall of a transmission shell; an interlocking pin hole for mounting the interlocking pin is formed between the two shifting fork shaft holes. According to the interlocking mechanism of the main and auxiliary boxes of the combined transmission, when working, the main box shifting fork shaft and the auxiliary box shifting fork shaft are matched with the interlocking pin; when the auxiliary box of the transmission is at a high-speed gear or a low-speed gear, the main box shifting fork shaft can move and rotate axially; when the rear auxiliary box is switched between the high-speed gear and the low-speed gear, the main box shifting fork shaft is mechanically locked in the axial direction; when the auxiliary box is put into a gear completely, the main box shifting fork shaft can move axially to be put into a gear; after the main box shifting fork shaft 1 is put into the gear, the auxiliary box shifting fork shaft is mechanically locked in the axial direction. The interlocking mechanism has many advantages of simple structure, high reliability, convenience in mounting and space saving, with a small number of parts; meanwhile, the interlocking mechanism can achieve a self-locking effect on an engaged state of the auxiliary box.

[detailed description of the invention]
Below in conjunction with the accompanying drawings the present invention is described in further detail:
See Fig. 1-Fig. 5, the present invention is directed to current a kind of novel single shift fork axle and handle the major-minor case combination of many gears
Automotive transmission, it is provided that a kind of simple, is not take up space, low cost, and the mechanical type major-minor case that reliability is high is mutual
Latch mechanism, main tank shift fork axle 1 and odd-side shift fork axle 3 are coupled together by the present invention by an interlocking plunger 2, main
Case shift fork axle 1 and odd-side shift fork axle 3 are supported on after case of transmission on partition wall 4 simultaneously, by transmission case
Bore an interlocking pin-and-hole being used for filling interlocking plunger 2 after body on partition wall 4, interlocking plunger 2 is contained in main tank shift fork axis hole
And between odd-side shift fork axis hole, add with on interlocking plunger 2 corresponding position when main tank shift fork axle 1 is in neutral gear position
One annular groove 6 of work, offers two grooves 5 on odd-side shift fork axle 3, and the distance between two grooves 5 is for becoming
Speed device odd-side is put into gear stroke.During rear odd-side is put into gear, odd-side shift fork axle 3 promotes interlocking plunger 2 to support into speed change
Device main tank shift fork axle 1 annular groove, is allowed to move axially, and odd-side is put into gear after end, and interlocking plunger 2 enters groove
5, release the control to main tank shift fork axle 1.Major and minor case being provided with of mutual interlocking gear of putting into gear beneficially protects odd-side
Lock unit during putting into gear from impact.
The work process of the present invention:
When interlocking plunger 2 is in annular groove 6, main tank shift fork axle 1 can be stoped to move axially and to put into gear, it is impossible to stop
Its rotation carries out block selecting.When secondary box of gearbox is in high gear or low gear, on odd-side shift fork axle 3
2 grooves one of them align with interlocking plunger 2 hole, interlocking plunger 2 is on odd-side shift fork axle 3 in two grooves
A groove among, at this moment interlocking plunger 2 does not contacts with main tank shift fork axle 1, and main tank shift fork axle 1 can be freely
Move axially and rotate, as shown in Figure 1 or 2 state.When variator main tank is in neutral gear position, main tank
The annular groove of shift fork axle 1 aligns with interlocking plunger 2 hole;When main tank is in and puts into gear, interlocking plunger 2 is extruded main tank
Shift fork axle 1 annular groove, in arbitrary groove of two grooves entering odd-side shift fork axle 3.
When rear odd-side carries out high and low gear switching, main tank shift fork axle 1 switches to neutral gear position, makes main tank shift fork
The annular groove of axle 1 aligns with interlocking plunger 2 hole, and in odd-side high to low gear handoff procedure, odd-side shift fork axle 3 pushes interlocking
Pin 2 climbs out of groove, moves to main tank shift fork axle 1 direction, supports in main tank shift fork axle 1 annular groove.At this moment, main
Case shift fork axle 1 is locked by axially machinery, it is impossible to move axially, as shown in Figure 3.Only put into gear when odd-side
After, one of them groove on odd-side shift fork axle 3 will align with interlocking plunger 2 hole, at this moment, and mobile main tank shift fork
Axle 1, the extruding by main tank shift fork axle 1 is slipped in the groove 5 of odd-side shift fork axle 3 by interlocking plunger 2, and it is right to release
The control of main tank shift fork axle 1, main tank shift fork axle 1 can move axially freely, puts into gear, main tank shift fork axle
After 1 is linked into gear, in arbitrary groove of two grooves that interlocking plunger 2 is got into odd-side shift fork axle 3, odd-side is dialled
Fork shaft 3 is locked by axially machinery, it is impossible to move axially, it is achieved major and minor case is put into gear interlocking.The present invention is conducive to
Protect auxiliary box synchronizer from impact during putting into gear.The odd-side state of putting into gear is played the work of self-locking simultaneously
With.
Above content is only the technological thought that the present invention is described, it is impossible to limit protection scope of the present invention with this, all
It is the technological thought proposed according to the present invention, any change done on the basis of technical scheme, each fall within this
Within the protection domain of bright claims.
