Provided is a straddle vehicle that allows for high design flexibility, that can absorb strong shocks applied in the up-down direction, and that can avoid contacting obstacles on the ground. The straddle vehicle includes a supported structure and a shock absorber. The supported structure includes a first element that performs a first function and a second element that performs a second function, the second element being located above a rear of the first element. The shock absorber includes an upper mounting portion and a lower mounting portion. The lower mounting portion of the shock absorber is connected to a swing arm, and the upper mounting portion of the shock absorber is connected to the second element.

A power unit includes at least one drive source that outputs rotational power to a drive target other than pumps; a first pump rotationally driven by the rotational power of the drive source; a second pump rotationally driven by the rotational power of the drive source, the second pump being different form the first pump; and a power transmission structure that transmits the rotational power of the drive source to the first and second pumps. The power transmission structure includes transmission components and transmits the rotational power to the first pump through one of the transmission components and to the second pump through another of the transmission components.

Disclosed is parallel hybrid drive for a motor vehicle, a motor vehicle, a method for operating a parallel hybrid drive in an all-electric mode, a method for operating a parallel hybrid drive in a direct drive mode, and a method for operating a parallel hybrid drive in a CVT mode. The drive for a motor vehicle includes an electric machine operable as a motor and generator, an internal combustion engine, a drive axle, and an epicyclic gear. The epicyclic gear includes: a first shaft connected to the electric machine; a second shaft connected to the internal combustion engine; and a third shaft connected to the drive axle. A clutch element is configured to firmly connect at least two shafts of the epicyclic gear to each other. A first brake element is configured to prevent rotation of the internal combustion engine in one direction of rotation.

A power train of a pedal vehicle includes a crankset axle and a first output plate having a first axis of rotation. The first output plate is coupled with a transmission chain or belt so as to drive the rear wheel of the pedal vehicle. The coupling between the crankset axle and the transmission chain or belt extends through a planetary gear train which rotates about a second axis of rotation. The crankset axle is further coupled to the first output plate by a first free wheel (16) which is arranged to prevent the first output plate from rotating slower than the crankset axle when the crankset axle rotates in the normal pedalling direction.

A system includes a support arm. The system includes an engine supported by the support arm. The system includes an armature supported by the support arm. The system includes a coupling device disposed around the armature and slidable between a first position in which the coupling device couples the engine to the armature, and a second position in which the coupling device is uncoupled from the engine.

A hybrid vehicle includes: a crankcase having a main chamber formed in a case body and accommodating at least a crankshaft, an input shaft, an output shaft, and a gear train, the crankcase further having a subsidiary chamber formed between the case body and a cover and accommodating at least a main clutch; a rotary member disposed in the subsidiary chamber so as to be capable of power transmission to the input shaft; and a power transmission member that transmits drive power from a drive motor to the rotary member.

A hybrid vehicle includes: an internal combustion engine; an electric motor; a controller; a transmission including an input shaft that receives power inputted from the internal combustion engine and the electric motor and an output shaft that outputs power to a drive wheel; and a clutch disposed in a first power transmission route between the internal combustion engine and the input shaft. The electric motor is connected to the input shaft so as to transmit power to the input shaft through a second power transmission route different from the first power transmission route. The controller changes the manner of controlling the electric motor upon switching of the state of power transmission from the internal combustion engine and the electric motor.
