Abstract
A clutch unit (20) includes a coupling element (23) configured to, in a power transmission enabled manner, couple an output shaft (13) of an engine (10) and an input shaft (16) of a hydraulic pump (15) driven by driving force of the engine (10), and a motor generator (18) configured to generate driving force separately from the engine (10), in which the coupling element (23) includes a driving-side coupling portion (23a) configured to be coupled to a first coupling portion (11a) that is provided in the output shaft (13), and a driven-side coupling portion (23b) configured to be coupled to a second coupling portion (15a) that is provided in the input shaft (16) and that is configured to be coupled to the first coupling portion (11a).
Claims11
A transmission unit comprising:
- a coupling element configured to, in a power transmission enabled manner, couple an output shaft of a driving source and an input shaft of a driven device driven by driving force of the driving source;
- and
- a second driving source configured to generate a driving force separately from the driving source,
- wherein a first coupling portion and a second coupling portion, which are configured to be coupled to each other, are provided on the output shaft and the input shaft, respectively,
- the coupling element includes
- a driving-side coupling portion configured to be coupled to the first coupling portion, and
- a driven-side coupling portion configured to be coupled to the second coupling portion, and
- the driving-side coupling portion has the same shape as the second coupling portion, and
- the driven-side coupling portion has the same shape as the first coupling portion.
