Voith: ECO-SWR Rotor Isolation Technology Retarder

ECO-SWR rotor idle separation technology

Crailsheim, Germany: Voith's rear-mounted water media retarder SWR uses a hydraulic retarder with engine coolant as a working medium and is now widely used in all types of trucks and buses to provide comfort and wear-free Auxiliary braking. In the new generation of Voith SWR, the motion components can be separated from the power system by the action of the clutch in the idle process, which means that ECO-SWR has many advantages besides SWR's driving safety, reduced operating costs, and environmental protection. He can further reduce the fuel consumption and the emission of harmful substances. Voith will present this new forward-looking product for the first time at the 2016 IAA Motor Show in Hannover. His debut is at the right moment, because according to the EU plan, CO2 emission limits for trucks and passenger cars will be fully implemented within the EU.

Now, the United States, Canada, Japan, and China already have CO2 emission-enforced limits for heavy-duty vehicles, and the European Commission's decision to issue similar regulations is only a matter of time. In this context, it is necessary to use all possibilities to further optimize the CO2 emission efficiency of heavy commercial vehicles. In this respect, Voith's SWR products have made outstanding contributions to the reduction of CO2 emissions from vehicles as a groundbreaking product, and its new generation of ECO-SWR will further realize the environmental protection concept.

At the 2016 IAA Commercial Vehicle Show in Hannover, Germany, Voith will show for the first time this latest generation of rear-mounted water media retarder ECO-SWR. During the idling process, his rotating parts and the powertrain system are separated by the action of the clutch. Through the rotor idle separation technology, he can further reduce the fuel consumption and harmful emissions of passenger cars and trucks. Based on this, he will reduce the vehicle's fuel costs and other taxes and fees, so that both car manufacturers and vehicle operators will benefit from this.

The application of rotor idling technology makes idle no extra power consumption

In the current hydraulic retarder products, the rotor and the whole vehicle power chain system are mechanically hard-connected, which means that the rotor keeps rotating during the running of the vehicle. In the ECO-SWR, the rotor and the powertrain system are connected via a clutch, so that the rotor can be separated from the power system during idling, and the additional power loss can be further reduced.

SWR has adopted its forward-looking design concept and has saved vehicle fuel consumption and improved operating comfort from reduced shift frequency. With its rotor-idle separation technology in its new generation of products, ECO-SWR will further reduce fuel consumption and maximize energy savings. For operators, it can save thousands of RMB each year. At the same time, this technology has made outstanding contributions in reducing the emission of CO2. He not only has great significance in environmental protection, but he can also help CO2 certification of the vehicles he loads.

ECO-SWR can also improve driver's driving comfort and safety. In terms of operation, the ECO-SWR is just like the previous Voith retarder product. The driver only needs to control the retarder handle or the brake pedal to request the retarder to participate in the brake. He can also integrate it into the vehicle. Braking management system. The rotor idling separation technique requires no additional operation and the rotor automatically separates at the end of each retarder operation without the retarder braking.

Using water as a working medium: lowering its own weight and reducing maintenance requirements

ECO-SWR is a rear-mounted hydraulic fluid retarder. The working medium used is engine coolant. Therefore, no additional working medium is required, which reduces the replacement and maintenance of the working medium. At the same time, wear-free retarding braking can take up to 90% of the entire vehicle braking task, thereby greatly reducing the wear of the main brake system such as friction plates. At the same time, under the action of its pump, the coolant flow rate of the vehicle can be increased, which indirectly increases the continuous braking power of the retarder by 20% to 30%. Even in the long downhill process, the retarder can be made. Keep the maximum available braking torque.
