Patent ID: 8689664

Claim:
A backhoe loader comprising: a front wheel; a rear wheel having a diameter greater than a diameter of the front wheel; and a multi-axis transmission configured to transmit power to the front wheel and the rear wheel, the multi-axis transmission including an input shaft to which power is inputted, a front output shaft coupled to the front wheel, a rear output shaft coupled to the rear wheel, the rear output shaft being disposed in a position higher than a position of the front output shaft, an intermediate shaft disposed between the input shaft and the front output shaft, a first power transmission mechanism configured to transmit power from the input shaft to the intermediate shaft, and a second power transmission mechanism configured to transmit power from the intermediate shaft to the front output shaft and the rear output shaft, the second power transmission mechanism including a first gear set including an intermediate gear fixed to the intermediate shaft, and a first front output shaft gear rotatably supported by the front output shaft, the first front output shaft gear being meshed with the intermediate gear, a second gear set including a second front output shaft gear rotatably supported by the front output shaft, the second front output shaft gear being fixed to the first front output shaft gear, and a rear output shaft gear fixed to the rear output shaft, the rear output shaft gear being meshed with the second front output shaft gear, and a driving method switching clutch disposed between the first and second front output shaft gears and the front output shaft, the driving method switching clutch being configured to allow and prevent transmission of power between the first and second front output shaft gears and the front output shaft, the first gear set being configured to reduce a speed of rotation of the intermediate shaft and to transmit the speed-reduced rotation of the intermediate shaft towards the front output shaft, and the second gear set being configured to reduce a seed of rotation of the intermediate shaft and to transmit the speed-reduced rotation of the intermediate shaft towards the rear output shaft, a reduction ratio of the second gear set being larger than a reduction ratio of the first gear set.
