At ConExpo/Con-Agg, Dana Rexroth Transmission Systems introduced a short-drop version of the R2 hydromechanical variable transmission (HVT), with pre-production testing by original-equipment manufacturers expected to begin by the end of this year.
The short-drop version of the HVT R2 is designed for a range of material-handling, pushback, and forestry applications. It incorporates a modular configuration with a redesigned transmission case that reduces input/output distance and it can be adapted for a variety of vehicles, including forklift trucks, empty container handlers, and terminal tractors. This hydromechanical variable transmission supports power outputs from 130 to 200 kW.
In addition, Dana Rexroth is designing an enhanced version of the HVT R2 that supports engine ratings up to 235 kW. It will supply vehicles with more power to simultaneously perform travel and work functions. Units will be available for pre-production testing by vehicle manufacturers in early 2018.
“Since production began on the long-drop version of the HVT R2, the power-split transmission program from Dana Rexroth has met industry demands for improved fuel economy, controllability, and reliable performance in real-world operating conditions,” said Roland Friedl, head of sales and product management for Dana Rexroth Transmission Systems. “This new short-drop version of the HVT R2 will deliver these benefits to an even wider range of material-handling vehicles and expand this technology to other off-highway applications.”
In production since 2015, the long-drop version of the HVT R2 from Dana Rexroth supports power outputs from 135 to 210 kW. This version was the first hydromechanical variable transmission from Dana Rexroth, and it is used on Kalmar’s Gloria generation of reach stackers as part of the Kalmar K-Motion drivetrain. Dana is exhibiting the long-drop version of the HVT R2 from Dana Rexroth at booth 84712 in the South Hall of the Las Vegas Convention Center.
