Single & Dual Pinion-Assist EPS

Single Pinion Assist EPS (SPEPS) integrates the electric assist mechanism into the primary steering gear pinion shaft. Single Pinion EPS has a design range comparable to Column-Assist EPS, but offers OEMs greater packaging flexibility, reduces OEM crossbeam strength/stiffness requirements and reduces torsional compliance of driving torque through the column and intermediate shaft assemblies.

• Capacity: 90+Nm assist torque (10.5+kN depending upon c-factor)
• Typical vehicle applications: A-B-C segments
• Premium steering feel, driver comfort and superior handling
• Modular design, scalable for global platforms

Dual Pinion EPS allows for the primary pinion to be optimized for vehicle dynamics and performance and a secondary pinion to be optimized for assist. It also provides additional design flexibility to locate the motor, controller and assist mechanism opposite the driver side of the vehicle underhood.

• Capacity: 100+Nm assist torque ~12.5+ kN rack load (depending on c-factor)
• Typical vehicle applications: C and D segments
• Premium steering feel, driver comfort and superior handling
• Modular design, scalable for global platforms
