| 20090143190 | TRANSMISSION SYSTEM FOR ALL-TERRAIN VAN - A transmission system includes a power transmission mechanism mounted on a chassis of an all-terrain van and front and rear wheel mechanism mounted on the chassis of the all-terrain van. The power transmission mechanism includes an engine mounted on the chassis in a transverse direction of the chassis. The engine includes a continuously variable transmission system and an output shaft extending toward the rear wheel mechanism. The power transmission mechanism further includes a transmission shaft extending between the engine and the rear wheel mechanism. The transmission shaft includes a first end in direct coupling with the output shaft of the engine and a second end coupled with a gearbox of the rear wheel mechanism such that output of the engine drives the output shaft, the transmission shaft, and the rear wheel mechanism. Thus, the transmission loss is reduced, and the transmission efficiency is enhanced. | 06-04-2009 |
| 20090239706 | Work Vehicle Having Hydraulic Stepless Speed Changing Apparatus - A work vehicle includes a hydraulic stepless speed changing apparatus and a gear type speed changing apparatus operable to receive output from the hydraulic stepless speed changing apparatus to convert it into a plurality of stages of speed. A return oil passage connected to a high-pressure side circuit of the hydraulic stepless speed changing apparatus is connected to a hydraulic tank. The return oil passage incorporates an unload valve and a throttle valve, between which an operably coupling mechanism is provided. This operably coupling mechanism switches over the unload valve to an unload condition in response to an operational displacement of a brake operating member for operating a brake to its braking side. | 09-24-2009 |
| 20100210413 | SHIFT CONTROLLER AND SHIFT CONTROL METHOD FOR AUTOMATIC TRANSMISSION MECHANISM - A shift controller for an automatic transmission mechanism is configured such that when the engine is in a driven state in which the engine is driven by a travel inertia force or the like and an accumulated pressure amount of the accumulator is equal to or less than a predetermined threshold, the excessive engine brake force, which is generated due to the accumulation of at least a portion of the hydraulic pressure generated from the mechanical hydraulic pump in the accumulator, is inhibited or reduced by conducting upshifting that relatively decreases the gear ratio of the automatic transmission mechanism. Therefore, the generation of the excessive engine brake force can be inhibited or reduced even when the engine is in the driven state and pressure accumulation is performed. | 08-19-2010 |
| 20140100078 | BRAKE SYSTEM FOR VEHICLE INCLUDING CONTINUOUSLY VARIABLE BELT TRANSMISSION - A brake system is provided for a vehicle equipped with a continuously variable belt transmission (hereafter a “CVT”) having a CVT input shaft and a CVT output shaft. The CVT functions as a clutch-disengagement action for isolating rotation of the CVT output shaft from the CVT input shaft when a rotary speed of the CVT input shaft is reduced to a certain, level. The vehicle is equipped with a prime mover driving the CVT input shaft so that an output rotary speed of the prime mover defines the rotary speed of the CVT input shaft. The vehicle includes an accelerator manipulator for controlling the output rotary speed of the prime mover. The brake system can cause a resistance against the rotation of the CVT output shaft using the accelerator manipulator to reduce, the output rotary speed of the prime mover to make the CVT function as the clutch-disengagement action. | 04-10-2014 |
| 20140287871 | Vehicle Speed Operating Device for Work Vehicle - A vehicle speed operating device for a work vehicle has a shift pedal that is disposed on a first lateral surface side of a body frame and is linked to an operating shaft of a continuously variable transmission via a first mechanical linkage mechanism, and a brake pedal, a speed maintenance mechanism and a second mechanical linkage mechanism are arranged on a second lateral surface side of the body frame. | 09-25-2014 |
| 20140378274 | Speed Change System for Work Vehicle - A speed change system for work vehicle having a continuously variable transmission device selects a first change gear ratio which is set larger than a smallest change gear ratio, when an engine rotational speed is a first set rotational speed which is set equal or close to an idling rotational speed of an engine; retains the change gear ratio of the continuously variable transmission device at the smallest change gear ratio, when the engine rotational speed is equal to or above a second set rotational speed set on a high-speed side relative to the first set rotational speed; and makes the change gear ratio of the continuously variable transmission device larger between the first change gear ratio and the smallest change gear ratio, as the engine rotational speed at that moment becomes lower, when the engine rotational speed is between the first and second set rotational speeds. | 12-25-2014 |
