摘要： A torque shock or vibrations caused by the rotary inertia of a hydrostatic continuously variable transmission is reduced to improve ride quality of a vehicle when excessive torque occurs in a torque transmission path between a crankshaft and a drive wheel. A motorcycle includes a hydrostatic continuously variable transmission rotatably driven by torque of a crankshaft of an internal combustion engine. A rear wheel is rotatably driven by torque from the transmission. A torque damper absorbs excessive torque occurring in a torque transmission path from the crankshaft to the rear wheel. The torque dampers include an input side torque damper disposed in an input side torque transmission path between the crank shaft and the transmission and an output side torque damper disposed in an output side torque transmission path between the transmission and the rear wheel.

摘要： An injector mounting structure for a V-type internal combustion engine includes an intake manifold arranged in a V-bank. A fuel supply pipe extends linearly in parallel to a crankshaft and is disposed in the V-bank. A pair of injectors are branched in an inverted V-shape in side view from the direction of the axial line of the fuel supply pipe from two branch portions P, Q apart from each other in the direction of the axial line of the fuel supply pipe and extend in parallel to each other and obliquely at an acute angle α with respect to a segment PQ connecting the two branch portions P, Q in top view. The injectors are mounted by fitting distal end portions of the pair of injectors respectively into mounting holes formed on air-intake pipes of the intake manifold on the respective sides.

摘要： A transmission structure of a power unit for a vehicle is provided with a hydrostatic continuously variable transmission for shifting and transmitting driving force from an internal combustion engine to a rear wheel. An oil pump supplies oil to a hydrostatic continuously variable transmission and a neutral/drive switching clutch which is arranged between the transmission and a rear wheel. A hydraulic piston adjacent to each set of driving friction plates and driven friction plates is moved by pressure in an oil pressure chamber and which connects and disconnects the driving force. An oil passage to the neutral/drive switching clutch is branched from an oil passage from the oil pump to the upstream side of the transmission. The resulting configuration prevents a lowering operating pressure of the neutral/drive switching clutch.
