Straight Forward OperationTypical Illustration (5) Side gear. (6) Driven clutch. (11) Driven clutch. (12) Side gear. (17) Spider. (22) Teeth of the spider. (23) Teeth of the driven clutches.When the machine has straight forward movement, teeth (22) on both sides of spider (17) are fully engaged with teeth (23) of driven clutches (6) and (11). The teeth of cams (21) are engaged with the teeth of center cam (15). The following combination forces the differential together. The reverse angle of the teeth on the clutches and on the spider, the force of springs (7) and (10), cams (21) and center cam (15). This forces the engagement of the teeth of the clutches with the teeth of the spider.In this condition, driven clutches (6) and (11) are fully engaged with spider (17). The driven clutches turn side gears (5) and (12) at the same speed as the bevel gear. The two side gears turn the axle shafts and the wheels at the same speed as the bevel gear.Forward Turn with Power

Forward Right Turn with PowerTypical Illustration (5) Side gear. (6) Driven clutch. (11) Driven clutch. (12) Side gear. (17) Spider.During a turn, the outside wheel travels a longer distance than the inside wheel. When the machine turns with power, the NoSPIN differential allows the outside wheel to turn faster than the speed of the bevel gear. The NoSPIN differential does not allow the inside wheel to turn at a rate that is slower than the speed of the bevel gear. The inside wheel turns at the same speed as the bevel gear.The teeth of the spider transfer the force to the inside driven clutch. The inside driven clutch turns the inside wheel at the same speed as the bevel gear. The inside driven clutch provides the power that is necessary to move the machine through the turn.The traction of the road causes the outside wheel to turn at a speed that is faster than the speed of the bevel gear. This causes the driven clutch for the outside wheel to turn faster than the speed of the bevel gear. The movement of one wheel faster than the movement of another wheel begins the clutch action of the NoSPIN differential.The cam for the driven clutch of the inside wheel has teeth. The teeth are engaged with the teeth of center cam (15). The teeth stay in the same position in relation to spider (17). The teeth of the inside drive clutch are engaged with the spider. The teeth on the other side of center cam (15) are used as ramps. The cam for the driven clutch of the outside wheel has teeth. The teeth move up the teeth of the center cam. This causes the outside driven clutch and the cam to move away from the spider and from the center cam. The outside driven clutch and the cam are not engaged with the spider or with the center cam.The driven clutch for the outside wheel
