Latest Patents

One of Hickey's latest inventions is the anti-gear-hopping device. This device is designed for a power transmission mechanism in automotive vehicles, specifically targeting the torque transfer case of four-wheel-drive systems. The anti-gear hopping device prevents undesired shifting between high range speed and low range speed modes of operation. It comprises a fluid pressure mechanism for controlling the movements of a shift member, a valve mechanism for actuating the fluid pressure mechanism, and a valve actuator. The fluid pressure mechanism may include either a diaphragm or a piston, which divides a chamber into two cavities that may be at different pressures. An output member linked to the diaphragm or piston controls shifting. The valve mechanism operates in multiple states to maintain desired pressure levels and prevent undesired shifting.

Another significant patent is the differential cross shaft retaining means. This invention provides an improved structure for retaining a differential cross shaft within a differential axle assembly. The assembly includes a casing that rotates about an axis, with a cross shaft disposed perpendicular to this axis. The design features a lock pin that secures the cross shaft in place, enhancing the reliability of the differential axle assembly.
