The security of a vehicle against is evaluated through of a classification denominated Thatcham, in order to obtain better insurances prices. The methods of theft have been improved over time, and therefore, the design of Mechanical Steering Column Lock (MSCL) also requires technological improvements. This work presents a design modification in the Mechanical Steering Column Lock (MSCL), with the objective to have a better security classification. This is a device that acts on the locking of the steering column, to protect against car thefts, called Deadlock. The timeline of the project and new design were discussed and defined between the Supplier and Product Development team, where was revised all the FMEA, Design Verification Plan (DVP) and Test Specification. Through this design, in addition to the decrease in the price of insurance, it was also possible to improve ergonomic comfort by ensuring a rotation in the position of the key mounted on the ignition cylinder.

Today's automotive industries are challenged to produce new products in less time than ever before. Over the past ten years, new design technologies have contributed to lower cost, higher quality products. Feature-based, parametric, associative CAD systems have streamlined engineering by enabling concurrent design of detailed models of all engineering deliverables that drive the design-through-manufacturing process. These deliverables include among others, behavioral models of components and assemblies. Using the Package analysis of a 4WD vehicle MacPherson Front Suspension as a study case, this paper presents in detail the virtual kinematical method used to simulate suspension, steering and tire system and identify dynamic clearances and interferences between components. Further describes also the engineering validation of the results on actual vehicles.
