Abstract

Pull-rod and clevis assembly is one of the most important part in single plate clutch. It is used for connecting a clutch pedal hydraulic cylinder output to clutch plate. Which is act as an engaging and disengaging lever in clutch plate assembly. While press the clutch plate Tensile and compression load act on the clevis and pull rod assembly. The yield strength of the material is one of the controlling factors in determining the optimum load for a pull rod and clevis connection. In clutch plate pull rod and clevis assembly is mainly made of steel and aluminium alloys (for light weight and absorb impact loads) or composite materials, composite materials is a material made from two or more constituent materials with significantly different physical or chemical properties that, when combined, produce a material with characteristics different from the individual components. The individual components remain separate and distinct within the finished structure. The new material may be preferred for many reasons: common examples include materials which are stronger, lighter, or less expensive when compared to traditional materials. As a pull rod and clevis unit it may transmit pull and push force to engage and disengage the clutch, in which it undergoes structural deformations. Thus, in this project we are modifying a pull rod and clevis unit in CRE-O design software and doing static structural analysis in ansys work bench 15.0 software by using advance materials. Thus, the part which is modeled is converted into IGES file to import in ansys work bench and static structural analysis is carried out at 10 kN of pressure load by applying various materials such as Aluminium Alloy and special alloy steel materials used in this project. This analysis helps to understand the stresses, strains, and total deformation which are focused on pull rod and clevis unit. Also, the factor of safety is determined. These parameters can facilitate deciding if this component is safe for use.
