摘要： A speed-change transmission apparatus for effecting a speed-changing on an engine drive force with utilizing a continuously variable speed-change device, a plurality of planetary transmission mechanisms and a plurality of clutches is constructed to be capable of effecting the speed-changing operation smoothly, regardless of a centrifugal force generated in the clutches. An output from the continuously variable speed-change device and a drive force from the engine are combined by a planetary transmission section. The drive force from this planetary transmission section is transmitted via a clutch section to an output shaft. First, second, third and fourth clutches of the clutch section are configured to be switched over respectively between an engaged condition and a disengaged condition, as clutch members are engaged with or disengaged from output side rotational members.

A planetary transmission section is configured to output the forward drive force in whichever case a hydrostatic stepless speed changing section is speed-changed to a forward rotation speed change state or a reverse rotation speed change state. A low speed transmission clutch couples a low speed side speed changing gear to a counter shaft to be rotatable therewith. A high speed transmission clutch couples a high speed side speed changing gear to the counter shaft to be rotatable therewith. A reverse transmission clutch couples a reverse transmission gear to an output shaft to be rotatable therewith.

摘要： Disclosed is a transmission apparatus for a tractor which is operable to transmit a forward drive force in a wide speed changing range to the traveling device and which is operable also to transmit a reverse drive force to the traveling device in an inexpensive manner and with good transmission efficiency. A planetary transmission section (30) is configured to output the forward drive force in whichever case a hydrostatic stepless speed changing section (11) is speed-changed to a forward rotation speed change state or a reverse rotation speed change state. A low speed transmission clutch (45) couples a low speed side speed changing gear (41), meshed with a low speed side output gear (31) of the planetary transmission section (30), to a counter shaft (44) to be rotatable therewith. A high speed transmission clutch (46) couples a high speed side speed changing gear (42), meshed with a high speed side output gear (32) of the planetary transmission section (30), to the counter shaft (44) to be rotatable therewith. An output shaft gear (48) is meshed with a counter gear (47) supported on the counter shaft (44) to be rotatable therewith. A reverse transmission clutch (52) couples a reverse transmission gear (51), meshed with the high speed side output gear (31), to an output shaft (43) to be rotatable therewith.
