Abstract
Official abstract text for this publication.
A gear transmission having a speed changing section includes a speed changing gear for setting a speed stage and a shift gear slidably mounted on a rotation support shaft and operated to engage and disengage with the speed changing gear, the speed changing section configured to speed-change inputted power and to output the resultant power via the rotation support shaft. An arrangement is provided for facilitating engagement of the shift gear with the speed changing gear even when respective end faces of the shift gear and the speed changing gear hit each other. A transmission mechanism (20B) is provided for outputting power of a rotation support shaft (24) to a traveling device. The transmission mechanism (20B) has a transmission flexibility portion (80) which allows free rotation of the rotation support shaft (24) by a set rotation angle.
First claim
Opening claim text (preview).
The invention claimed is: 1. A gear transmission comprising: a speed changing section comprising a speed changing gear for setting a speed stage and a shift gear slidably mounted on a rotation support shaft and operated to engage and disengage with the speed changing gear, the speed changing section configured to speed-change inputted power and to output resultant power via the rotation support shaft; and a transmission mechanism configured to output the power of the rotation support shaft to a traveling device, the transmission mechanism having a transmission flexibility portion allowing free rotation of the rotation support shaft by a set rotational angle, wherein the transmission mechanism comprises: a first transmission gear gear-coupled to the rotation support shaft; a rear wheel differential mechanism having an input shaft coupled to the first transmission gear and configured to output power from the first transmission gear toward the rear wheel as the traveling device; a second transmission gear gear-coupled to the rotation support shaft; a rotation transmission shaft gear-coupled to the second transmission gear; and a front wheel output shaft coupled to the rotation transmission shaft for outputting power from the rotation transmission shaft to a front wheel as the traveling device; and wherein the transmission flexibility portion is provided between the first transmission gear and the input shaft and also between the second transmission gear and the rotation transmission shaft.
