An automobile starter motor (larger cylinder). The smaller object on top is a starter solenoid which controls power to the starter motor and engages the Bendix drive.. A starter (also self-starter, cranking motor, or starter motor) is a device used to rotate (crank) an internal-combustion engine so as to initiate the engine's operation under its own power.
A Bendix drive is a type of engagement mechanism used in starter motors of internal combustion engines.The device allows the pinion gear of the starter motor to engage or disengage the ring gear (which is attached to the flywheel or flexplate of the engine) automatically when the starter is powered or when the engine fires, respectively.
Starter ring gear attached to a flywheel. In cars with a manual transmission, the starter ring gear is fitted to the outer diameter of the flywheel.The ring gear is usually fixed to the flywheel through use of an interference fit, [2] which is achieved by heating the ring gear and so that thermal expansion allows it to be placed around the flywheel.
Once the engine starts, the key-operated switch is opened and the solenoid opens the contacts to the starter motor. All modern starters rely on the solenoid to engage the starter drive with the ring gear of the flywheel. When the solenoid is energized, it operates a plunger or lever which forces the pinion into mesh with the ring gear.
The Hucks starter (invented by Bentfield Hucks during WWI) is a mechanical replacement for the ground crew. Based on a vehicle chassis the device uses a clutch driven shaft to turn the propeller, disengaging as the engine starts. A Hucks starter is used regularly at the Shuttleworth Collection for starting period aircraft. [3]
The flywheel may also perform a part of the balancing of the system and so by itself be out of balance, although most engines will use a neutral balance for the flywheel, enabling it to be balanced in a separate operation. The flywheel is also used as a mounting for the clutch or a torque converter in most automotive applications.
Also called the GM small corporate pattern and the S10 pattern. This pattern has a distinctive odd-sided hexagonal shape. Rear wheel drive applications have the starter mounted on the right side of the block (when viewed from the flywheel) and on the opposite side of the block compared to front wheel drive installations.
This is a list of auto parts, which are manufactured components of automobiles.This list reflects both fossil-fueled cars (using internal combustion engines) and electric vehicles; the list is not exhaustive.
