Description

Technical Field

[0001] The present invention relates to the technical field of engine flywheel housing power output, and particularly relates to a detachable flywheel housing power output device. Background Art

[0002] On special-purpose vehicles, there are generally some special devices, such as the tipping mechanism of dump trucks, the lifting mechanism of crane trucks, and the refrigeration equipment of refrigerated trucks. Generally, such special-purpose vehicles need to output the power of the engine through a power output device. Traditionally, gears are integrally reserved on one side of the flywheel housing for easy power output. However, using this integrated solution has a single structure and is difficult to modify. With the increasing market competitiveness, it is difficult to support it alone at high costs. Therefore, it is particularly important to design a replaceable and assembled non-traditional integrated structure, which not only has a wider universality and is suitable for various special-purpose vehicles, but also greatly reduces production costs and improves competitiveness. However, when using an assembled power output device, there has always been a major problem. Since it is detachably assembled outside the flywheel housing, in addition to considering the operation stability and reliability of the detachable power output device, it is also necessary to consider the overall quality and assembly stability.
