Carraro Group exhibited several drivetrain components during CONEXPO 2020.
The company demonstrated its ability to offer a wide range of solutions from Basic to Premium, leveraging as much as possible the design, modularity and scalability of its products to address the most advanced solutions together with the ones using more “frugal” technology, thus obtaining best cost and performances.
Today Carraro is able to offer a comprehensive product portfolio of complete drivelines for all the most popular construction equipment machines, such as backhoe loaders, tele boom handlers, compact wheel loaders and small wheel loaders, wheel excavators and soil compactor. In addition to that, Carraro Engineering is able to develop innovative solutions for additional construction equipment and special applications.
Electrification: the new path
Leveraging the 25 years of experience in development and supply of integrated drive systems for material handling applications for electric traction, Carraro more recently extended its portfolio to hybrid electric machines and electric powertrains.
Now Carraro can offer the design of the whole system, combining its traditional mechanical know-how with strong electronic competences. Able to support all the electric architecture topologies, Carraro is able to lead the complete e-powertrain through a dedicated ECU, then sizing and integrating the most suitable electric modules: from motors and generators, to inverters, batteries and battery management system to obtain the best performance for the entire system.
Carraro displayed three main examples of its innovations both in terms of products and service capabilities, highlighting its unique value proposition from the component to the complete machine.
- eTCH90 Long Drop/Torque Converter Full Powershift Transmission: designed to become a parallel electric hybrid unit. Suitable for several equal size tire machines, starting from teleboom handlers.
- eTB220C/Gearbox specifically developed for full-electric applications, able to have minimum power losses even at high input rotation speed.
- FLS 3.2/Full Powershift Hydrostatic Gearbox, able to fulfill the performance demand of several machines, ranging from small wheel loaders to teleboom handlers.
All the gearboxes above are controlled by a software developed to run in the Carraro proprietary ECU, fully compliant with ISO 25119 (Functional Safety).
Moreover, for all the powertrain applications Carraro can also enable to achieve further fuel efficiency and productivity through the simultaneous control of the whole powertrain (i.e. engine and transmission) thanks to its competence in developing control software to be injected in its proprietary Electronic Control Units.
Carraro booth used a special augmented reality tool to go more in depth with its technical solutions to better understand how the company can fit its products on different applications.
