This paper mainly for automotive design and manufacturing technology jacks were studied.Firstly, a comprehensive analysis of domestic and foreign cars with extremely heavy items and structural features of the current development, discussed the development of new car with a jack significance. In the comprehensive analysis and comparison of existing car with a jack program features, based on the proposed electric manual rapid switching jack design.This paper focuses on a selected vehicle program was extremely heavy items conceptual design and detailed design, also completed the research work required design drawings.According to the National Bureau of Statistics show that Chinas personal car ownership in 1999 reached 5.34 million, in 2002 domestic car has broken one million annual sales in 2003, the trend has continued to grow. Of auto parts companies only supply the domestic market demand, production and export annually about 500 million vehicles with a jack to the world. Taking into account the countrys automotive manufacturing extremely heavy items yield tremendous, if we adopt the method proposed in this paper the design and manufacture of the product, you can save a lot of material costs, its economic benefits are substantial. Meanwhile, the optimized products under the premise of reducing production costs, the reliability and stability has also been improved to some extent.Key word: Car with a jack； optimal design；development status
