ABSTRACT
With improving environmental protection consciousness and the serious energy crisis， to research and develop the clear, energy-saving and safe auto become the new direction of development of automobile industry. Electric vehicle, which has much advantages, such as no emission, pluralism and high-efficient of energy utilization, and conveniently realizing intelligence erc, is about to become one of the focal points in researching and developing new—type automobile. The design and research takes a wheel reduction unit applied on reduced wheel-drive electric vehicle as the subjective ． Research for the type of structure has been done in this thesis which will contribute to the application capability of reduced electric wheel ． Load balancing structure is introduced into the drive line design of the planetary wheel reducer to fulfill the advantage of planetary transmission ． In order to decrease weight and volume as well as save to material，the researcher optimized the volume of the planetary transmission． For easy to assemble the break system and the wheel--hub while reducing components number, a connection supporting part is designed ． The most particular design is the transmission housing with pivots for assembling the upper and lower control arm ， the stabilizer as well as the steering linkage ． Optimization of the suspension, steering system and stabilizer bar has made for assembling the wheel reducer more accurate ， then the optimization result feedbacks to modify the reducer design .For the purpose of guaranteeing the strength of the wheel reducer in work.
