With the continuous development of market economy, the demand for construction machinery market is increasing, thus supporting the machine maintenance products also urgently needs to be innovation and improvement. Many construction machinery such as trucks, trucks, all types of military vehicles, container trucks, tankers, buses, harvesters, dump trucks, tractors, all kinds of special vehicles operating in the field is prone to failure, some failures such as tire burst and the nut loose such a situation, you need to quickly repair this machine, but please maintain a dedicated staff to have a lot of inconvenience, in order to meet market demand, the research is a way to quickly loosen (tighten) the nut The increasing power of institutions - Planetary tire unloading device. Based on the analysis and comparison of several common strengths and weaknesses of institutions by force and to improve upon a force increasing mechanism (planetary gear Force organizations) made. The agency uses a planetary gear structure, body size, high efficiency, easy to carry, transmission power range, etc., has good practicability, it is easy for each user equipped with a car, especially in the rural region, where the vehicles rarely go to a special service for maintenance, as poor rural roads, agricultural vehicles on the road bumps make the car very easy to loose nuts, leading to all kinds of failure, tire disposal device which can play in these failures a role, can be said that the market here is very broad. With further improvement of the planetary transmission technology, prospects in this area more widely. In this paper, the choice of transmission line and the structural design of a detailed calculation of check instructions and to use pro / E completed the design of the virtual prototype. Then adopted the principle of rationality and feasibility of their simulation was validated and achieved good results.
