ABSTRACT:
Left and right side clutches (15) and side brakes (18), each fashioned into a frictional disk type, are disposed between an axle-driving power output shaft (12) and left and right wheel axles (11). Axially spaced left and right side clutch gears (13) which carry, at boss portions thereof, left and right clutch housings (14) extending towards each other are rotatably mounted on the output shaft. The clutch of each side is disposed within each of the housing (14) and includes frictional elements (17) supported by the housing. The brake of each side is disposed within a space around each housing (14) and includes frictional element(s) (20) supported by the housing.
The clutch and brake of each side are operated by a single mechanism including a shifter sleeve (22), slidably mounted on the housing (14), and a pivotal clutch control arm (21) extending through a peripheral wall of the housing. The arm engages the sleeve which is biased to move towards the clutch-engaging and brake-disactuating direction by the clutch spring means (23).
The clutch and brake assembly is disposed in a compact fashion around the output shaft within the length of the shaft. The shifter sleeve and clutch spring means control both of the clutch and brake of each side.
