With a total of five patents to his name, Hiketa's innovations have enhanced vehicle performance and functionality.

Latest Patents

Hiketa's latest patents include a groundbreaking four-wheel drive vehicle design. This vehicle features an engine with an output shaft that extends transversely, along with a transmission connected to one side of the engine through a clutch or torque converter. The design incorporates an inter-axle differential mechanism made up of a planetary gear mechanism, as well as a first inter-wheel differential mechanism of a bevel gear type. This mechanism transmits driving force to the first wheels, which are positioned closer to the engine than the second wheels. Additionally, a second inter-wheel differential mechanism transmits driving force to the second wheels through a transfer gear mechanism. The vehicle also includes a propeller shaft mechanism and an inter-axle differential restricting mechanism to control differential operation.

Another notable patent is the vehicle four-wheel drive system, which includes a transmission with an output gear connected to an idle gear. This idle gear is rotatably positioned on an input member of a front inter-wheel differential gear mechanism located in the front axle assembly. The system features a transfer shaft with multiple inter-axle differential gear mechanisms that offer different torque split ratios. A selecting mechanism allows for the connection of one of these inter-axle differential gear mechanisms with the idle gear, enabling the establishment of a desired torque split ratio between the front and rear wheels.
