Abstract: A hydraulicmachine continuous transmission of loader has been designed and the dimension parameters of each parts has been determined.  This paper analyzed the speed characteristics of hydraulic system, the speed characteristics of planetary and the speed characteristics of hydraulicmachine system. On basis of the 3D model, the kinematics simulation of the transmission was done and its shifting conditions and speed characteristic curve were studied and compared with the theoretical values. The results prove that the structure of this transmission is reasonable and can meet the transmission ratio and expected speed requirements.

 Key words: hydraulicmachine； transmission； continuous transmission； speed characteristics
