The gear shifting auxiliary device specifically works in the following process:
the shift assist device state is shown in fig. 2 in neutral. At this time, the gear-shifting inner shifting head 8 is positioned at the neutral position by the pin assembly 10, the limiting ring 1 is in a horizontal state, the two inner side working surfaces of the limiting ring are horizontally symmetrical and have a certain distance from the working surface of the strong magnet 2, and no magnetic attraction is generated between the two inner side working surfaces. I.e. the shift assist device is not active.
The mid-range shift assist device state is shown in fig. 3. During the middle range of gear shifting, the inner shifting head 8 rotates by a certain angle, and the control surface vertex of the inner shifting head contacts with the pin assembly 10, and is the maximum peak position of gear shifting force. The transverse gear shifting rod 7 is driven by the rotation of the shifting head, the transverse gear shifting rod 7 drives the limiting ring 1 to rotate by the same angle, at the moment, the working surface on one side of the limiting ring 1 is far away from the strong magnet 2, and the other side of the limiting ring is close to the strong magnet 2, and magnetic attraction starts to be generated between the limiting ring and the strong magnet 2. That is, the shift assist device starts the intervention operation.
The shift assist device state is shown in fig. 4 at the end of a gear shift. Under the magnetic attraction of the working surface of the limiting ring 1 and the strong magnet 2, the limiting ring 1 rotates in the gear engaging direction in an accelerating way and drives the transverse gear shifting rod 7, and the transverse gear shifting rod 7 drives the gear shifting inner shifting head 8 in an accelerating way to assist in completing gear engaging operation and achieve the effect of enhancing the gear engaging suction feeling. Because protective sheath 3 slightly is higher than strong magnet 2 working face, final spacing ring 1 and protective sheath 3 laminating spacing guarantee the accurate gear angle of hanging of interior plectrum to there is magnetic attraction continuously. The magnetic attraction existing at the moment can assist in providing an effective anti-disengagement force for the gear shifting inner shifting head 8. I.e. the shift assist device is continuously operated.
When the gear-shifting force is larger than the resultant force of the self-locking force of the gear-shifting inner shifting head 8 and the gear-shifting auxiliary device anti-disengagement force, the gear-shifting inner shifting head 8 and the limiting ring 1 rotate towards the gear-shifting direction at the same time. When the gear is engaged, the limiting ring 1 is rotated by a certain angle, and the magnetic force on the working surface attracted by the magnetic force of the strong magnet 2 completely disappears. I.e. the shift assist device is deactivated.
By the aid of the gear shifting auxiliary device, the suction feeling of the gear entering in the second half of gear shifting operation is improved, the in-place definition of the gear entering is improved, the accuracy of gear shifting angles of a gearbox and the consistency of gear shifting angles of all gears are improved, the reliability of gear shifting positions and the gear disengaging prevention capability are improved, and finally the control comfort and the driving safety of the gearbox and the whole vehicle system are obviously improved.
