Electric Power Steering Belt

The role of the electric power steering belt is to transfer torque from the motor to the steering mechanism to assist with driving.

The Electric Power Steering (EPS) belt features unique characteristics that offer exceptional durability and high load capacity, contributing to a longer vehicle lifespan. Our EPS belts are used in vehicles from the world’s leading electric, hybrid and conventional brands.

In EPS system configurations with an off-axis servo unit, a motor mounted on the side of the rack housing drives the ball screw mechanism via a toothed rubber belt to provide steering assistance. 

Electric Power Steering Belts are produced with a Neoprene, HNBR or EPDM polymer, and reinforced with fiberglass, aramid kevlar.

Electric Power Steering Rack Belts provide optimized acoustics and trouble-free tooth engagement as they are developed with oblique or slanted tooth.

Steering Rack Belts are potential replacement belts for Lincoln, Chevrolet, Volvo, Ford, Golf, Audi, Tesla, Land Range Rover, Evoque, BMW, Mercedes Benz, Volkswagen, VW, Tiguan, Passat, CC, B7, Variant, Q3, SEAT, Alhambra, Leon, Sharan, Touran, Mustang, F150, Explorer, Focus, Fusion, Mondeo, S-Max, Galaxy, Tourneo, Connect, Escape, C-MAX, Kuga, Transit, Connect, Wagon, Furgon, V40, Canyon, MKZ, Ranger, Alfa, Romeo, Cadillac, Jaguar, Jeep, GMC, Dodge, Lexus, Buick, Chrysler, Hyundai, Kia, Skoda, Toyota, Camaro, Silverado, Colorado, Corvette, Porsche.

Typical Mode of Failure

One of the leading failure modes in today’s electric rack and pinion assemblies is belt malfunction. As with all rubber parts in a vehicle, the drive belt in these systems is exposed to wear, tear, and environmental conditions. If this basic rubber belt fails, it used to mean the entire rack and pinion system would be compromised.

Yonghangbelt offers a comprehensive selection of belts to replace damaged ones and preserve the original unit.
