Description
Nissan technicians consistently test steering friction because it is a critical component for understanding and improving chassis dynamic performance. Due to the inaccuracy of a previous machine used, a new apparatus has been constructed to improve the repeatability and efficiency of a steering friction test. The automation and accurate calibration of the test ensures more accurate data compared to the previous machine. This will lead to more accurate decisions regarding the friction applied between the rack and pinion of a vehicle steering system. The Rack Pull Friction Test is an extremely important test performed by the Nissan Chassis Dynamics Technicians. How the driver experiences the car and if it is suitable for their needs is how the company can sell their vehicles. The test relates to how the customer experiences the steering effort of the vehicles when making small steering wheel corrections. It is important that the customer experiences a minimal steering effort on center feel but still strong enough to maintain control of the vehicle. Since the steering ability is a critical component of car handling, the testing must be performed to the optimum ability. Therefore, the attempt to perfect this test is important to improve the quality and the assurance that the vehicle is at maximum ability.
