Transmission Development for Construction Equipment

The transmission is considered to be a key component of a construction equipment vehicle. The transmission capabilities have to support the functionality of the vehicle, especially in the high frequency forward reverse application. In sensitive operating of piling and loading as well as in high loaded transportation, the transmission - with its high functionality and efficiency - define the value of the machine. Electronic systems secure optimum operating conditions for the engine and transmission and guarantee the best efficiency of the whole machine in its application. Technologies like IVT (infinitely variable transmission) are promising potential reductions of fuel consumption compared to standard solutions like power shift transmission.

AVL Approach

The extensive engineering experience and the use of efficient development and simulation tools are the foundation for AVL‘s innovative solutions. This is also the best basis to introduce new transmission technologies in the application field of construction equipment. AVL has developed all types of transmissions such as manual, automated manual, automatic and double clutch.

  • Development of complete transmissions and axles or components
  • Simulation and evaluation of new technologies or new solutions
  • Optimization of existing transmission (automated transmissions, IVT´s) including software and controls
  • Automation of existing manual transmissions including software and control systems
  • Testing of transmissions and axles
  • Design assessments and consultancy

Customer Benefits

We provide senior specialists for transmission engineering and at the same time share best practice and development methodology with other industries. In this way, experiences in hybridization, hydraulics, electronics, electric drives and engine development are carefully evaluated and combined most effectively for every project. The technology level and development methodology are consequently extended by AVL internal research projects. This provides a solid basis to achieve the agreed results within cost and time parameters, and secures innovative products with high customer satisfaction.
