A shifting apparatus for a manual transmission able to shift two shift stages, of which selection positions are different but shift positions are the same, using a single fork and a single sleeve. Compared to the related art in which a fork and a synchronization sleeve are provided to each of two independent shift stages, the full length of the transmission is reduced, thereby reducing the weight and manufacturing costs.

A gear-shifting mechanism driving device for allowing a speedy and accurate gear-shifting operation has a light weight even in the case where a shift spindle is short. The gear-shifting mechanism driving device includes a transmission for selectively establishing a gear combination by the turning of a shift spindle for turning a master arm, and an actuator as a power source for turning the shift spindle, in which the gear-shifting mechanism driving device includes a reduction gear shaft provided in a power transmission path between the actuator and the shift spindle, a first gear provided on one end side of the reduction gear shaft to receive power from the actuator side, and a second gear provided on another end side of the reduction gear shaft to transmit power to the shift spindle side. The reduction gear shaft is made of a torsion bar.

Disclosed is a utility work vehicle having an engine section at a rear portion of a vehicle body. The engine section includes an engine having an output shaft oriented laterally along a right/left direction of the vehicle body, a speed changer device having an input shaft oriented laterally along the right/left direction of the vehicle body, the speed changer device being disposed rearwardly of the engine, a belt type stepless speed changer device disposed on one right/left side of the engine and the speed changer device and configured to transmit power from the engine to the speed changer device. A clutch is disposed between the engine and the belt type stepless speed changer device. A space is formed downwardly of the clutch between the engine and the belt type stepless speed changer device. At a portion downwardly of the speed changer device and facing the space, a front wheel driving output shaft extends forwardly from the speed changer device. To the front wheel driving output shaft, a transmission shaft is connected coaxial with the front wheel driving output shaft, the transmission shaft extending through the space forwardly.

A compound transmission shift mechanism is disclosed. The shift mechanism includes a plurality of gears configured on at least one transmission shaft with at least one synchronizer configured to engage at least two of the plurality of gears. The shift mechanism includes a control system configured to engage and position the synchronizer into alignment with the at least two of the plurality of gears. Additionally, the shift mechanism includes at least one damping assembly configured on the control system and operatively connected to the synchronizer.

Provided is a mounting structure including an electronic control unit, a plurality of support brackets, a transaxle case, an intermediate bracket protruding from the transaxle case toward a rear side of the vehicle, and an engaging projection. The engaging projection is a projection that is provided to at least one of an upper surface of the intermediate bracket or a bottom surface of the electronic control unit in a region where the intermediate bracket is in surface contact with a mounting surface of the transaxle case, the engaging projection protruding in a direction toward the upper surface of the intermediate bracket and the bottom surface of the electronic control unit. The engaging projection presses the intermediate bracket against the mounting surface of the transaxle case responding to displacement of the electronic control unit at the time of vehicle collision.

The invention refers to hydraulic rotation transmissions and can be used in power transmissions and transmissions where the stepless ratio variation is essential. It can also be used as stepless speed transmission for vehicles (FIG. 1). Getting any transmission ratio with higher performance factor is achieved by applying in the hydraulic transmission new scheme, including motionless and movable bodies containing two coupled rotors, composing of camshafts with pistons and separated by motionless wall. Transmission ratio varies from 0 to maximal value displacing the movable body in axial direction by means of overhanging control arm.
