Optimal functionality, combined with the highest degree of efficiency, poses the central challenge to today's drive systems.
Power shift transmission, dual-clutch transmission and stepless transmission with different variator systems represent today's technological state of the art. In view of constantly rising energy costs, hybrid systems are also under development.

hofer develops drive systems for

  • Tractors
  • Wheel loaders
  • Municipal vehicles
  • Telehandlers
  • Forklifts
  • Harvest machinery

as well as similar applications, from concept study and function sample to series readiness. Overlay transmissions are one of our special fields.

The interdisciplinary project teams are covering the competences spectrum including design, prototyping, test bench and drive tests, software for transmission and vehicle control system.

The newly developed stepless transmission VDC represents a milestone in CVT and IVT technology. The VDC ("Variable Double Clutch") transmission combines the specific advantages of double clutch transmissions with the functional advantages of hydrostatic and electric variators. Further areas of special emphasis include the development of stepless drives for ATVs. The combination of a vane pump with a vane motor in conjunction with an overriding drive enables continuous adjustment of the transmission ratio without gear shifting.
