Description
Technical Field
The utility model belongs to the gearbox field relates to an AMT gearbox, especially a built-in actuating mechanism's of shifting AMT gearbox.
Background
The gearbox and the AMT gear shifting mechanism of the AMT gearbox running on the market are in separated states, namely the gearbox and the AMT gear shifting actuating mechanism are two assemblies. This structure is comparatively inconvenient in the assembly to spare part is more, and manufacturing cost is higher, and in addition, two assemblies still can have the risk of oil leak in its casing department when connecting. Therefore, it is necessary to design an AMT gear shift driving device which is compact in structure, convenient to assemble and free from the risk of oil leakage.
Through a search for a patent publication, no patent publication that is the same as the present patent application is found.
Disclosure of Invention
An object of the utility model is to provide a structural design scientific and reasonable, compact structure, convenient assembly and do not have built-in gear shift actuating mechanism's AMT gearbox of oil leak risk, easily realization.
The utility model provides a its technical problem realize through following technical scheme:
the utility model provides a built-in actuating mechanism's of shifting AMT gearbox comprises casing, gearbox mechanism and gearshift, its characterized in that: the shell consists of a front shell and a rear shell which are connected through bolts, and a cavity formed by the front shell and the rear shell is internally provided with a gearbox mechanism and a gear shifting mechanism which are arranged up and down; the gear shifting mechanism is composed of a gear shifting motor, a ball screw, a gear shifting fork and a shifting fork supporting shaft, the rear shell is provided with the gear shifting motor, the ball screw arranged in the cavity is connected to the gear shifting motor in a driving mode, the shifting fork is sleeved on the ball screw in a penetrating mode, the shifting fork supporting shaft is arranged on a shifting head of the gear shifting fork in a penetrating mode, and two ends of the shifting fork supporting shaft are respectively positioned on the front shell and the rear shell.
And a screw nut in threaded connection with the ball screw is arranged on the ball screw in a penetrating manner, belleville springs are arranged on two sides of the screw nut in a penetrating manner, and the screw nut and the belleville springs are arranged inside a shifting fork sleeve.
The utility model discloses an advantage and beneficial effect do:
1. according to the AMT gearbox with the built-in gear shifting driving mechanism, the gearbox mechanism and the gear shifting mechanism are integrated in one shell, so that the size of the whole device is reduced, the use of parts is reduced, and the whole device is light; meanwhile, the gear shifting mechanism is arranged inside the shell of the gearbox, so that the risk of oil leakage is reduced; in addition, through the setting of shift fork back shaft, can bear the reversal moment of torsion that the shift fork shift in-process appears, protection ball, extension this gearshift's life.
2. This built-in actuating mechanism's of shifting AMT gearbox sets up the dish type spring through the both sides at screw nut, namely the outside of screw nut and dialling between the cover inside wall, has reduced ball and has improved ball's life at the produced impact effect of the in-process at striking limit.
3. The utility model has the advantages of structural design scientific and reasonable, have compact structure, convenient assembly and do not have the oil leak risk, protect ball, increase of service life, easily realize, be an AMT gearbox that has the built-in actuating mechanism of shifting of higher novelty.

Detailed Description
The present invention will be described in further detail with reference to specific examples, which are provided for illustrative purposes only, and are not intended to be limiting, and the scope of the present invention should not be limited thereby.
The utility model provides a built-in actuating mechanism's that shifts AMT gearbox comprises casing, gearbox mechanism 1 and gearshift, and its innovation part lies in: the shell consists of a front shell 10 and a rear shell 5 which are connected through bolts, and a cavity formed by the front shell and the rear shell is internally provided with a gearbox mechanism and a gear shifting mechanism which are arranged up and down; the gear shifting mechanism comprises a gear shifting motor 4, a ball screw 6, a gear shifting fork and a shifting fork support shaft 8, wherein the gear shifting motor is installed on the rear shell, the ball screw arranged in the cavity is connected to the gear shifting motor in a driving mode, a shifting sleeve 9 of the gear shifting fork is arranged on the ball screw in a penetrating mode, a shifting fork support shaft is arranged on a shifting head 7 of the gear shifting fork in a penetrating mode, and two ends of the shifting fork support shaft are located on the front shell and the rear shell respectively.
The ball screw is provided with a screw nut 2 in threaded connection with the ball screw in a penetrating way, two sides of the screw nut are provided with belleville springs 3 in a penetrating way on the ball screw, and the screw nut and the belleville springs are arranged inside the shifting fork sleeve.
The utility model integrates the gear box mechanism and the gear shifting mechanism into a shell, thus reducing the volume of the whole device and reducing the use of parts, and leading the whole device to be light; meanwhile, the gear shifting mechanism is arranged inside the shell of the gearbox, so that the risk of oil leakage is reduced; in addition, through the setting of shift fork back shaft, can bear the reversal moment of torsion that the shift fork shift in-process appears, protection ball, extension this gearshift's life.
The ball screw is arranged inside the shifting fork, and the shifting motor drives the ball screw to reciprocate inside a shifting sleeve of the shifting fork, so that the shifting fork is pushed to drive the synchronizer mechanism to shift. The shifting fork support shaft is used for bearing the reverse torque generated in the shifting process of the shifting fork and protecting the ball screw.
