Definitions

  • the invention relates to a drive unit, in particular for driving a vehicle, according to the preamble of claim 1.
  • a drive unit with a traction motor is known, to which an auxiliary motor for optionally driving auxiliary units is assigned.
  • the auxiliary motor which is used to drive the auxiliary units when necessary, is arranged on the side of the traction motor.
  • the auxiliary units are arranged at a distance from the free end areas of both motors and are essentially structurally assigned to the auxiliary motor.
  • the disadvantage here is the considerable installation space.
  • the invention has for its object to show an arrangement of an auxiliary motor with less need for installation space for a generic drive unit.
  • a single-star motor designed as an internal combustion engine is arranged in a free end region of the traction motor as an auxiliary motor.
  • a particularly advantageous space-saving arrangement is achieved according to claim 2 with a single-star engine, which is designed as a 4-cylinder 2-stroke engine with a crank loop engine.
  • a single-star motor which is described in more detail, for example, in EP-A-0 187 930, a short, compact and powerful auxiliary motor is achieved for a space-saving arrangement.
  • the invention is advantageous not only in terms of the size of the auxiliary motor. It is also of considerable advantage with regard to the overall arrangement in that auxiliary units provided in the front end region of the traction motor can be used, provided that installation space can be used, and thus a separate arrangement requiring additional installation space is omitted.
  • This advantageous arrangement is additionally supported in a simple manner in that the single-star motor is arranged in alignment with an engine shaft of the traction motor with the interposition of a switchable clutch.
  • the coupling be in rotary connection on the outside with driven disks of enveloping gears provided in several planes in the free end region of the drive motor for driving the auxiliary units.
  • the above-described switchable clutch can be designed so that the auxiliary units can be driven by the single-star engine when the vehicle is at a standstill, idling or possibly under a heavy load on the drive motor. According to claim 4, however, an operating mode is also conceivable for the switchable clutch such that, if necessary, only a part of the auxiliary units is driven by the single-star motor. This especially for the case that one or more of these separately selectively driven auxiliary units have to deliver an increased power that cannot be achieved while maintaining the given speed of the traction motor, such as, for example, increased air conditioning power and / or increased electrical consumption from the vehicle electrical system at low driving speed or a stop -and-go driving style of the vehicle.
  • An assembly 1 serving to drive a vehicle comprises a traction motor 2 serving to drive the vehicle, with numerous auxiliary assemblies arranged in the end region.
  • Auxiliary units are provided with a coolant pump 3 with a drive pulley 4 and a power steering pump 5 with a drive pulley 6.
  • the drive pulleys 4 and 6 lie with a driven pulley 8 assigned to the drive shaft 7 of the traction motor 2 in one plane of an enveloping transmission 9.
  • Further auxiliary units are a generator 10 with a drive pulley 11 and an air conditioning compressor 12 with a drive pulley 13.
  • the drive pulleys 11 and 13 are located with a further, the output shaft 14 assigned to the engine shaft 7 in a different plane of a second enveloping gear 15.
  • an auxiliary motor 17 is arranged in alignment, which serves to selectively drive the aforementioned auxiliary units 3, 5, 10, 12.
  • the auxiliary motor 17 arranged in the free end region of the drive motor 2 is designed as a single-star motor 18.
  • the single-star motor 18 is designed as a 4-cylinder, 2-stroke engine with a crank-loop engine (EP-A-0 187 930).
  • the switchable clutch 16 is connected on the outside in a rotationally fixed connection to the driven disks 8 and 14 of the cladding gears 9 and 15 of the auxiliary units 3, 5 and 10, 12 divided into two groups.
  • the clutch 16 is switchable in such a way that either both groups of auxiliary units 3, 5 and 10, 12 or, depending on requirements, one of groups 3, 5 and 10, 12 can be operated via the single-star motor 18.
  • the single-star motor 18 arranged on the traction motor 2 can also be designed with the switchable clutch 16 as a retrofit kit.
