Description
Technical field
The utility model relates to a kind of 1/5 gear selector forks of gearbox, belong to the technical field of automobile gearbox.
Background technique
For double clutch gearboxes between engine and speed changer, it is that one kind can transmit power and cut off power
Transmission mechanism.
Double clutch gearboxes can be divided into the double clutches of wet type, the double clutches of dry type, its effect mainly guarantees that automobile can be put down
Steady starting, when gear shift, mitigate the shock loading of transmission gear and prevent power train from overloading.Double clutch gearboxes possess shift
More directly, the advantages that power loss is smaller, but failure occurrence probability is higher.Automobile, which needs to drive by shift fork in gear shift, to be synchronized
Device is engaged to corresponding gear set and realizes gear shifting action, and traditional selector fork mechanism stable performance is bad, is easy to happen out of supply
Or the of serious failure of gear is accidentally hung, it not can solve the requirement of hand shift automobile.
Summary of the invention
In order to solve the problems in the existing technology, the utility model provides a kind of 1/5 gear of gearbox shift group
Fork, the selector fork have the characteristics that structure is simple, compact, driving torque greatly, small in volume, transmission efficiency it is high.
The technical solution adopted in the utility model is: a kind of 1/5 gear selector fork of gearbox, it includes fork, fork
Using U-shaped structure, fork reinforcing rib is welded in fork；Two neighboring vertical sides of fork connecting plate add with fork respectively
Strengthening tendons and the protrusion on fork top are welded to connect；The right end face of fork connecting plate is flushed with the raised right end face on fork top
And be welded to connect with the outer circle middle position of pipe, the other side in the outer circle middle position of pipe and one end of piston connecting plate are welded and are connected
It connects, the other end spigot of piston connecting plate and the spigot of piston are welded to connect；It is welded at the top of the outer circle middle position of pipe
Brake plate.
Two ends of the fork are equipped with the liner of injection molding.
The top of the fork is equipped with top injection molded layers.
The beneficial effects of the utility model are: this 1/5 gear selector fork of gearbox includes fork, fork uses U-shaped
Type structure is welded with fork reinforcing rib in fork；Two neighboring vertical sides of fork connecting plate respectively with fork reinforcing rib and
The protrusion on fork top is welded to connect；The right end face of fork connecting plate flushed with the raised right end face on fork top and with pipe
Outer circle middle position be welded to connect, one end of the other side in the outer circle middle position of pipe and piston connecting plate is welded to connect, living
The spigot of the other end spigot and piston of filling in connecting plate is welded to connect；Braking is welded at the top of the outer circle middle position of pipe
Plate.The selector fork passes through Combination Welding by different stamping parts, with structure is simple, compact, driving torque is big, small in size heavy
The advantages that amount is light, transmission efficiency is high, prevents out of supply and loses rank, while reducing shift time, elongate member service life, effective
Product processing cost is reduced while improving production efficiency.
Detailed description of the invention
Fig. 1 is a kind of schematic perspective view of 1/5 gear selector fork of gearbox.
In figure: 1, fork, 2, fork reinforcing rib, 3, fork connecting plate, 4, pipe, 5, brake plate, 6, piston, 7, piston connection
Plate, 8, liner, 9, top injection molded layers.
Specific embodiment
Fig. 1 is the structural schematic diagram of a kind of 1/5 gear shifting fork of gearbox and cross bar main body.1/5 grade of this gearbox
Position selector fork, it includes fork 1, and fork 1 uses U-shaped structure, is welded with fork reinforcing rib 2 in fork 1；Fork connecting plate
3 two neighboring vertical sides are welded to connect with the protrusion on 1 top of fork reinforcing rib 2 and fork respectively；The right side of fork connecting plate 3
Side end face flushes with the raised right end face on 1 top of fork and is welded to connect with the outer circle middle position of pipe 4, in the outer circle of pipe 4
Between the other side of position and one end of piston connecting plate 7 be welded to connect, the other end spigot of piston connecting plate 7 and piston 6
Spigot is welded to connect；Brake plate 5 is welded at the top of the outer circle middle position of pipe 4.
Two ends of fork 1 are equipped with the liner 8 of injection molding.The top of fork 1 is equipped with top injection molded layers 9.
Concrete operating principle are as follows: this 1/5 speed shift shift fork of gearbox is assembled in gearbox, the shift fork is in speed change
4 sets of the tube cooperations on shifting shaft carry out axially position in case, and fork 1 moves handsetting gear piece in the axial direction to complete
Gear shifting action；Brake plate 5 and the brake of gearbox are used cooperatively, and main function is changed when fork 1 moves in the axial direction
When gear operation, guarantee that selector fork positions fast accurate, it can be to operator with apparent mechanical prompt when reaching gear；It is living
Plug 6 is connected with transmission system, plays the role of being axially moved offer power to selector fork.
By adopting the above technical scheme, fork 1 uses U-shaped structure, and U-shaped structure has that structure is simple, and intensity is high, not variable
The end of shape, U-shaped structure needs to be molded with top, because the needs of fork 1 are matched with synchronous ring, increasing injection molding is in order to anti-
Only fork is directly contacted with the synchronization ring of gearbox, is avoided the selector fork and the mutual friction damage of synchronous ring, is increased shift
The service life of shift fork；The main function of brake plate 5 when fork moves in the axial direction need to stop when, guarantee that shift fork positioning is fast
It is fast accurate.
