Abstract

PURPOSE:To reduce the entire structure by constructing a gear change unit integrally with change gear group and shift fork group in the transmission cover. CONSTITUTION:Plural sets of supporting rod pair 1-4 are juxtaposed to support the shift forks 5-8 advancable/retractable in shifting direction respectively on said rod 1-4. While shift rods 9, 10 are arranged advancably/retractably in same shifting direction with the shift forks 5-8 to be advanced/retracted through a shift cylinder 12. Furthermore, change levers 13, 18 rotatable in selecting direction approximately in perpendicular with the shifting direction are arranged for each pair of shift fork 5-8. The change levers 13, 18 are rotated through select cylinders 15, 20 in selecting direction to be engaged with the shift forks 5-8. With such arrangement, the entire size can be reduced.

(Prior Art) Conventionally, such a transmission has been developed for use in route buses and the like. For example, when the clutch lever is operated and the change lever is shifted according to a shift pattern, the change lever unit converts this shift operation into an electrical signal and supplies it to the control unit, which processes the signal in a predetermined manner and drives the shift fork group. A signal is supplied to the gear switching unit, and the gear is changed in response to the driver's shift operation, making it easier for the driver to switch gears than when using a change lever, control link, and transmission, which are all mechanical. It is constructed so that the operating effort can be reduced, and has the advantage of improving fuel efficiency compared to a fully automatic transmission.

By the way, the gear switching unit includes a plurality of cylinders that operate according to signals from a control unit and a switching lever that is orthogonally moved by these cylinders.
A shift fork group formed within the transmission cover is selectively moved by engagement of the switching lever to perform gear switching. That is, the shift fork group that holds the slider that switches the transmission gear is arranged inside the transmission cover together with the transmission gear, and the gear switching unit that operates the shift fork group is integrally attached to the outside of the transmission cover. The shift fork is driven by the switching lever inserted from the outside.

For example, in the case of a six-speed transmission, a total of four cylinders are required: one cylinder that moves the switching lever in the select direction and three cylinders that move the switching lever in the shift direction. The problem was that the cylinder and switching lever were installed outside the transmission cover, making the structure larger.
