Design Of Bell Crank Lever
What Is A Bell Crank Lever
Designing of the bell crank lever involves considering the various forces acting on it. Due to this the bell crank is subject to bending and crushing stress. 2.2.1 Determination of forces acting on it A bell crank lever in which the effort and load arm are at an angle to each other. Bell Crank Lever. A bell crank lever is an angled Class 1 lever. It is a Class 1 lever because the fulcrum is between the load and the effort force. The bell crank lever is used when the effort force must be at an angle, usually a right angle, to the load.

Suspension Bell Crank
Parametric design charts are proposed for the central-lever steering linkage, generated for simplified reference configuration mechanisms, the geometry of which is defined by only four parameters. This highlights the fact, yet not generally acknowledged, that the steering law ensured by a mechanism with adjacent central joints (known as bell crank mechanism), can be identically generated by a triple central joint variant of the same. Particular configurations are identified in which the length of the central lever does not affect the wheel-to-wheel transmission function of the mechanism, permitting a simplified synthesis for the cases in which the maximum stroke of the input member is imposed as a design specification.
