Purpose of the thesis is to construct a tool for car wheel change. Car wheels can be heavy and hard to handle and therefore the company Movomech intends to develop a tool that makes wheel change easier. Movomech does not have any similar product and because of this the work was condition less.The intended users of the product is tire workshops and there for the work began with investigation of these. The reason of the investigation was to see how wheel change is done and how tire workshops are planed. The tire workshops? crew?s opinions were also considered and above all one important conclusion was made. The tool must be easy to use so the wheel change is at least done as quickly as it is done manual. With this and with the demand specification was construction ideas made. The ideas were evaluated and the most suitable idea is constructed. The construction includes important geometry, force analysis, strength calculations and bearings calculations. The result is a 3D-CAD-model of the tool.The demand specification did not fully succeed to be fulfilled. The demand that it should be clear in front of the wheel screws can cause some problems with the biggest wheels with the biggest screw circle. This believes to happen rarely. Besides that has the cost been kept down by not using expansive components nor too expansive materials. But the tool must be complemented with chain hoist and rail system.2
