Patent ID: 7028801

Claim:
A brake system of a multi-wheel vehicle, said multi wheel vehicle comprising: a pair of first drive wheels disposed at one of front and rear portions of the vehicle; a pair of second drive wheels disposed at the other of the front and rear portions of the vehicle, wherein at least either said pair of first drive wheels or said pair of second drive wheels are steerable; a first transaxle including a first transaxle housing, a pair of first axles disposed in said first transaxle housing to be connected to respective ones of said first drive wheels, a first differential section disposed in said first transaxle housing to differentially connect said first axles to each other, and a power take-off (PTO) section for taking off rotational force synchronous with the rotation of an input to said first axles, said PTO section being externally attached to said first transaxle housing; and a second transaxle including a second transaxle housing, a pair of second axles disposed in said second transaxle housing to be connected to respective ones of said second drive wheels, a second differential section disposed in said second transaxle housing to differentially connect said second axles to each other, and an input section for transmitting the rotational force of said PTO section of said first transaxle to said second differential section, said input section being disposed in said second transaxle housing, said brake system comprising: a pair of first brake devices for braking said respective first axles, wherein said first brake devices are disposed on said respective first axles in said first transaxle housing; a second brake device for braking said input section of said second transaxle, wherein said second brake device is disposed in said second transaxle housing; and a common brake operation device operatively connected to said pair of first brake devices and said second brake device so that said pair of first brake devices and said second brake device can be simultaneously actuated for braking by operating said common brake operation device.
