Application and compatibility
The presented electric power steering rack with motor drive is designed for the Audi TT 8J generation with a petrol engine and manual transmission. The system’s design has been developed for the dynamic characteristics of this model, maintaining appropriate stiffness, sensitivity, and predictable response during both city and highway driving.
The electric power steering system in the Audi TT 8J works in conjunction with vehicle sensors and body electronics, which is why selecting the correct steering rack is crucial for the proper operation of electronic stability control systems and driving comfort.
Construction and technical characteristics
The discussed steering rack motor drive unit belongs to the Steering racks and housings category. The assembly integrates an electric motor responsible for generating steering assistance force and a mechanism that transfers torque to the steering rack. This configuration allows for smooth adjustment of assistance depending on vehicle speed and system load.
The electric solution eliminates the need for a traditional hydraulic pump, hoses, and fluid, which reduces power loss and simplifies maintenance. At the same time, the appropriate stiffness of the system is maintained, which is essential in a car with a sporty character like the Audi TT 8J.
