STEERING GEAR AND LINKAGE
2016 – MX-5 – Steering
STEERING GEAR AND LINKAGE
Purpose/ Function
-
The rotational movement input from the intermediate shaft is converted to a linear movement in the horizontal direction of the steering rack by the rack and pinion mechanism, and then transmitted to the tires and wheels.
Construction
-
The steering gear and linkage consists of the pinion shaft, Electric Power Steering (EPS) motor, reduction gear, steering rack, and torque sensor.
-
A size and weight-reduced rack and pinion system steering gear has been adopted.
-
Rigid-mount has been adopted instead of the mounting rubber, enhancing the steering rigidity.
-
By using O-rings on the support yoke and rack bushing, quietness has been improved.
Operation
-
The drive force generated by the EPS motor is transmitted via the reduction gear to the steering rack as a pinion torque.
-
The rotational movement input from the steering shaft is converted to a linear movement in the horizontal direction of the steering rack by engaging the pinion shaft connected to the steering shaft and teeth of the steering rack. This linear movement is transmitted via the inner and outer ball joints to the steering knuckle to steer the tires left or right.
Fail-safe
-
