To show how the steering linkage is related to toe-in. To demonstrate the effect of wheel offset. To observe the dynamic stability of the wheel under running conditions. To measure the forces on the steering link. To show how the weight of the car affects self centering. Description Students often experience difficulty in understanding the principles of front wheel set-up on road vehicles, since the geometry involves angles in three dimensions. This apparatus represents a half to third scale model of the wishbone and king pin arrangement of a front wheel suspension complete with a 250mm wheel on an adjustable stub axle. The king pin assembly includes a steering link to demonstrate how a real car works. The basic version of the apparatus, HTM21, shows precisely how castor, camber and king pin indication are set up and how center point steering is achieved. A dished wheel and means of altering the offset are included so that everything affecting center point steering can be varied. Vernier scales measure the castor angles and king pin inclination, while toe in and camber angles are measured from a longitudinal and vertical datum in the way in which they would be determined on a real vehicle. A hand driven rotating turntable simulates a rolling road, and may be turned at a slow enough speed to study wheel stability under running conditions. This equipment is part of a range designed to both demonstrate and experimentally confirm basic engineering principles. Great care has been given to each item so as to provide wide experimental scope without unduly complicating or compromising the design. Each piece of apparatus is self-contained and compact. Setting up time is minimal, and all measurements are made with the simplest possible instrumentation, so that the student involvement is purely with the engineering principles being taught. A complete instruction manual is provided describing the apparatus, its application, experimental procedure and typical test results..
