HTM21 Castor, Camber, King Pin Inclination

HTM21 Castor, Camber, King Pin Inclination

Students often experience difficulty in understanding the principles of front wheel set-up on road vehicles, since the geometry involves angles in three dimensions.

The apparatus shows precisely how castor, camber and king pin inclination are set up and how centre point steering is achieved. A wheel and means of altering the offset are included so that everything affecting centre 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.

A comprehensive instruction manual for lecturer and student, giving full details on apparatus assembly and operation as well as example results. All necessary assembly and operational tools are provided.
