Latest Patents

One of MacAfee's latest innovations is a vehicle axle designed for dual operating modes, allowing vehicles to seamlessly transition between two-wheel and four-wheel drive. This axle is composed of a pair of flanged axle shafts interconnected through an axle differential. Notably, one of the axle shafts features inner and outer sections that can be selectively coupled or uncoupled via a shiftable clutch collar, which is actuated by a responsive vacuum motor controlled by signals to facilitate mode selection. In two-wheel drive mode, the outer section of the axle shaft rotates freely while the inner section and axle differential engage for efficient power delivery. Conversely, in four-wheel drive mode, both sections cooperate for synchronized wheel rotation through the differential.

Another notable patent includes a comprehensive vehicle drive system featuring first and second operating modes. This system incorporates a transfer case and front drive mechanism to enable smooth transitions between power distribution modes. The control system allows operators to switch between two-wheel drive and four-wheel drive configurations via a sequence of actions that engages components driven by a chain and sprocket assembly. This innovative approach enhances vehicle performance and versatility.
