Method for converting a vehicle, method for providing a drive unit, drive unit and vehicle

A method for converting a vehicle

• by changing its drive unit from an internal-combustion drive principle to an electrically operated drivetrain,
• whereby a vehicle for an internal-combustion drive principle has a drive unit with an internal-combustion engine, and whereby a vehicle or an electrically operated drivetrain has a drive unit with an electrically operated motor,
• whereby the vehicle belongs to the group of commercial vehicles, special vehicles, mobile work machines and watercraft,
• whereby the drive unit with an internal-combustion engine has
• a crankshaft for generating rotary motion driven by a core engine, and
• at least one main power take-off for transferring the rotary motion to a drivetrain of the vehicle, and
• at least one internal power take-off for transferring the rotary motion to unit-internal auxiliary units, and
• optionally at least one drive-independent auxiliary power take-off to transfer the rotary motion to external units,
• with the following steps:
• a. the drive unit with an internal-combustion engine is mechanically separated from the vehicle as follows:
• i. Main power take-off:
• the coupling between the main power take-off and the drive gear is released.
• ii. Internal drives connecting the core engine and the auxiliary units:
• the connection between the auxiliary units and their connections to the rest of the vehicle are separated;
• whereby the auxiliary units remain at least partially, preferentially completely, on the unit.
• iii. Auxiliary power take-offs:
• if auxiliary power take-offs are present that lead to external units, they will also be disconnected.
• iv. Other connections:
• all other mechanical, thermal and electro-mechanical connections are unfastened, such as screw joints;
• hoses and plugs, especially including control connections and the power supply;
• so that the drive unit with an internal-combustion engine and the connected auxiliary units are removed from the vehicle and disconnected at a number of interfaces;
• b. the drive unit with at least one electrically operated motor is provided as a replacement unit, whereby the replacement unit
• i. is spatially compatible with the available installation space of the removed drive unit with an internal-combustion engine and
• ii. is mechanically compatible with the interfaces and
• iii. behaves functionally identically at all interfaces.
