Dana Rexroth Transmission Systems is working with engine manufacturers in the off-highway industry to support European Stage V emissions regulations.
Set by the European Union, these diesel engine standards further restrict emissions limits for non-road mobile machinery, including vehicles for construction, material handling, and agriculture applications. In 2019, the regulations will go into effect for engines below 56 kW (75 hp) and above 130 kW (174 hp). Required compliance for engines in the 56 to 130 kW (75 to 174 hp) range will begin in 2020.
“Original-equipment manufacturers are looking to Tier One suppliers with efficiency-focused technologies to stay ahead of tightening emissions regulations for all vehicle categories in markets around the world. Our hydromechanical variable transmission (HVT) platform is already prepared for Stage V emissions standards, and we are collaborating with leading engine manufacturers to develop transmission control software that will allow us to deliver a fully compliant solution,” said Bernd Schmidt, general manager of Dana Rexroth Transmission Systems.
A product of the joint venture between Dana Incorporated and Bosch Rexroth, HVTs from Dana Rexroth significantly reduce fuel consumption by decreasing engine speeds throughout the duty cycle and also at idle, when speeds can drop to as low as 600 rpm.
The long-drop version of the Dana Rexroth HVT2 has been in production for reach stacker applications since 2015, supporting power outputs from 135 to 210 kW (180 to 282 hp). The long-drop version of the HVT2 is featured on Kalmar’s Gloria generation of reach stackers as part of the Kalmar K-Motion drivetrain.
