Engine starting device for vehicle

摘要

A vehicle engine starting device includes a drive starter gear provided on an output shaft of a transmission and a driven starter gear provided on a crankshaft of an engine are meshed, not only is it possible to start the engine by cranking the crankshaft by means of the driving force transmitted from a driven wheel without requiring a starter motor, but it is also possible to prevent the dragging of the transmission since the driving force is not transmitted to the crankshaft via the transmission. Further, since the gear ratio of the drive starter gear and the driven starter gear is set so that the rotational speed of the crankshaft attains a rotational speed that can start the engine when the vehicle speed reaches a predetermined vehicle speed for starting the engine, it is possible to reliably start the engine by cranking the crankshaft at an optimum speed.

主权项

1. An engine starting device for a vehicle in which a transmission changes and transmits the speed of rotation of an input shaft connected to a crankshaft of an engine to an output shaft connected to a driven wheel, the transmission comprising an input side pivot point that has a variable amount of eccentricity from the axis of the input shaft and rotates together with the input shaft, a one-way clutch that is provided on the output shaft, an output side pivot point that is provided on an input member of the one-way clutch, and a connecting rod that has opposite ends connected to the input side pivot point and the output side pivot point and moves back and forth, wherein the engine starting device comprising a drive starter gear that is provided on the output shaft or on a differential gear connected to the output shaft, and a driven starter gear that is provided on the crankshaft and meshes with the drive starter gear.
