Latest Patents

Nishida's latest patents include a "Drive pump arrangement for working vehicle" and a "Vehicle for civil engineering work." The drive pump arrangement patent describes a working vehicle that comprises two pumps for driving hydraulic motors, which are provided for opposite running devices individually. It features a valve mechanism that allows the vehicle to operate in either a low-speed state, where fluid is supplied from the pumps to the motors individually, or a high-speed state, where combined fluid from the pumps is supplied to the motors in series. This design includes an operating assembly that prevents the vehicle from turning at high speeds, ensuring safety even if the driver inadvertently operates the vehicle in this state. The second patent, the vehicle for civil engineering work, outlines a vehicle equipped with an engine, a torque converter, and planetary gearing sets. This vehicle can turn sharply at slow speeds, thanks to its innovative turning drive mechanism that allows for differential rotary speeds on either side.
