Embodiment Construction

[0027] figure 1 An exemplary embodiment of a flywheel 1 is shown, which is driven by an output shaft 2 of an internal combustion engine, not shown in detail. In the example shown, the flywheel 1 is formed from a sheet metal part 3 , which, in other embodiments, can also be formed from an injection molded part or from a forged material. The flywheel 1 can, for example, receive a clutch, establish a connection to a torque converter or be used as the primary-side input of a dual-mass flywheel. Alternatively, a clutch assembly already fitted on the transmission input shaft of the subsequent transmission may be connected to the flywheel 11 . Such a clutch assembly can be, for example, a dual clutch of a dual clutch transmission. Flywheel 1 is driven by output shaft 2 . For this purpose, the flywheel 1 is fixedly connected to the output shaft 2 , for example by means of connecting means, not shown in detail, such as screws.

Abstract

The invention relates to a flywheel on an output shaft of an internal combustion engine, said output shaft being driven by a starter in order to start the internal combustion engine. According to the invention, the starter ring gear that is driven by the starter is located axially between the housing of the internal combustion engine and the flywheel. The starter ring gear is only driven whilst torque is transmitted from the starter to the starter ring gear.

Description

technical field [0001] The invention relates to a flywheel which is received on an output shaft of an internal combustion engine and has a flywheel ring gear for starting the internal combustion engine by means of a starter. Background technique [0002] Such flywheels are known from the prior art. A flywheel ring gear is fixed to this flywheel in a rotationally fixed manner, with which the pinion of the starter cooperates and through which the output shaft is driven. Especially in hybrid applications and start / stop systems, the frequent engagement of the starter is uncomfortable. Contents of the invention [0003] It is therefore the object of the present invention to provide a flywheel with a flywheel ring gear in which frequent start-up operations of the internal combustion engine can be carried out comfortably. [0004] This task is solved by a flywheel, which is fixedly received on the output shaft of the internal combustion engine, which has a flywheel ring gear fo...
