Embodiment Construction

[0018] see now Figure 1-3 , the engine starter system 10 includes: a pinion 12; a starter motor 14; a shaft 16 drivably connected to the motor and the pinion; a ring gear 18 meshing with the pinion; and a one-way clutch (OWC) 20 which Supported on the shaft for alternately breaking and making the drive connection between the shaft and the pinion.

[0019] The shaft 16 is supported for rotation on a bearing 22 fixed to the starter housing 24 and a further bearing 26 at the right-hand side of the pinion 12 .

[0020] The ring gear 18 is formed on a flywheel 28 which is drivably connected to a crankshaft 30 of an engine 32 with an OWC (one way clutch - not shown).

[0021] The one-way clutch 20 includes a set of clutch actuating elements 34 preferably in the form of rollers or balls spaced from each other about an axis 36 . Each clutch element 34 is located within an annular space defined by a slightly radially inclined outer surface 38 formed on the pinion 12 and an inner cyl...

Abstract

A torque transfer system for cranking an engine includes a starter motor, an engine crankshaft, a pinion, a ring gear engaged with the pinion and driveably connected to the crankshaft, and a one-way clutch for alternately opening and closing a drive connection between the pinion and the starter motor.

Description

technical field [0001] The present invention mainly relates to a device for starting an internal combustion engine, in particular to a device for an internal combustion engine with an energy-saving flameout-starting system. Background technique [0002] An electrical starting motor (electric motor) is used to crank and start an engine in a motor vehicle. Under normal driving conditions, the engine runs continuously after being started by the starter motor. To improve fuel economy, the economizer kill-start system shuts down the engine after the vehicle has been stopped for a predetermined amount of time and automatically restarts the engine in response to the driver of the vehicle depressing the accelerator pedal, which indicates a need to accelerate the vehicle. These actions occur without turning the ignition on or off. [0003] In one form of an economizer fire-start engine cranking system, a pinion gear is permanently meshed with a ring gear that is drivably connected ...
