Better braking – with Voith retarders for commercial vehicles
With Voith retarders, up to 90 percent of all braking actions can be performed without wear. This represents a significant increase in safety. Retarders protect the service brakes, thus reducing expenditures on spare parts and maintenance. At the same time, transport capabilities increase due to higher average speeds.
High brake performance is essential when it comes to stopping a truck that weighs several tons. Classic friction brakes can reach temperatures of up to 1000 degrees under demanding conditions such as adaptive braking on the highway or on long downslopes. This leads to a rapid reduction in braking efficiency. Voith retarders provide the solution: The permanent hydrodynamic endurance brake system ensures reliable, wear-free braking. This protects the service brakes and ensures they are always available. It is no surprise that endurance brakes in buses and trucks are a legal requirement throughout Europe.
Voith retarders – the advantages at a glance
- Greater safety throughout the entire speed range ensured by high retarder brake performance and cold service brakes
- Downhill cruise control – using the v-constant function, the retarder maintains constant driving speed on downward slopes
- Lower operating costs – considerably longer periods without the use of service brakes results in fewer visits to the repair shop and lower maintenance costs
- Low weight – Voith retarders are light, allowing optimal use of load limits
- Higher transport capabilities – due to higher and more uniform average speeds
- Lower consumption – more uniform speeds and proactive driving behavior saves fuel
- Non-polluting – up to 80% lower emissions of brake dust

The Voith retarder portfolio – the right solution for every vehicle
Together with vehicle manufacturers such as Mercedes-Benz, Volvo, Renault, MAN, and many more, we are developing customized retarder solutions.
Water retarders
The Voith Aquatarder provides braking using the engine coolant. This means there is no additional operating medium, no additional oil change, and no adjustment work. Voith’s secondary water retarder was awarded the European Transportation Prize for Sustainability and the ECW Innovation Label Award for its innovative, energy-saving and non-polluting approach.
Oil retarders
Using an oil supply that is independent of the transmission fluid, the oil in Voith’s oil retarders can tolerate the maximum permissible operating temperatures. The braking energy is transferred via the heat exchanger to the vehicle’s cooling circuit, where it is effectively dissipated.
Hydrodynamic braking – retarder design and operation
Hydrodynamic braking – retarder design and operation
- Hydrodynamics makes wear-free braking possible.
- The magnitude of the braking torque depends on fill level and speed.
- The retarder is perfectly integrated into the vehicle braking management system.
- The braking energy is converted into heat and dissipated via the vehicle cooling system.
Wear-free braking – how a retarder works
Inline and offline retarders – a question of transmission
Secondary retarders can be divided into inline and offline retarders. Retarders can be attached to the gearbox, or installed in the drive train. They are directly connected to the vehicle’s universal joint shaft.
Offline retarders are connected to the universal joint shaft by means of a high gear integrated into the gearbox. Owing to the gear ratio, offline retarders are lighter and have a more compact design than inline retarders, while producing the same braking performance.
