Download now of 50 Front Axle & Steering Geometry fIntroduction Primary function of the steering system is to achieve angular motion of the front wheels to take a turn. This is done through linkage and steering gear which convert the rotary motion of the steering wheel into angular motion of the front road wheels. fSecondary functions STEERING GEOMETRY The term "steering geometry" (also known as "front-end geometry") refers to the angular Relationship between suspension and steering parts, front wheels, and the road surface. Because alignment deals with angles and affects steering, the method of describing alignment measurements is called steering geometry. After studying the conditions of Ackerman steering geometry[3] of correct and slip free steering and trapezoidal mechanism[3], the inner wheel and outer wheel lock angles were calculated. Inner wheel lock angle = 450 Outer wheel lock angle = 28.010 Followed by this, calculations were performed to calculate the turning radius of the vehicle.

[1] This geometry today is known as Ackermann steering because it was the lawyer Rudolph Ackermann who patented it, patent no. 4212 (1818). The basic geometrical setup of an Ackermann steering system is shown in Fig. 2. The early advantage of Ackermann-Jeantnat steering geometry model is a geometric configuration of linkages in the steering of a car or other vehicle when the vehicle is running at low speed [38] [39] [40]. The purpose of The steering system will convert the rotary motion of the steering wheel into the angular turn of the front wheels. Steering wheel rotates the steering column. The steering gearbox is fitted to the end of this column. Therefore, when the wheel is rotated, the cross shaft in the gearbox oscillates. The cross shaft is connected to the drop arm. Abstract and Figures. This article focuses on the synthesis of a steering mechanism that exactly meets the requirements of Ackermann steering geometry. It starts from reviewing of the four-bar Steering Geometry Joint O1 and O2 are revolute joints and joints A and B are spherical joints as shown in Figure 1. The relative orientation of two links connected at joint can be recorded in terms of value of the angles measured by potentiometer and using electronic instrumentation. At four joints (two spherical and two revolute) of the Ackermann Geometry Ackermann Geometry Ackermann steering geometry solves the problem of wheels on the inside and outside of a turn needing to scribe circles of different radii. Rudolf Ackermann (1764 - 1834) was the patent agent for German horse drawn coach builders "Lankensperger". They submitted a patent in 1818, but Eramus Darwin was said to have had prior claim to the invention in 1758. At the same time the steering system is able to withstand the external requir
