The Research And Development Of YB1502 Electric-hydraulic Automatic Transmission

The technology of AT (automatic transmission) is the key technology to improveperformance of the vehicles. The research focuses on YB1502 electric-hydraulic AT,the new developed AT. Firstly it gives a brief introduction of the development in ATboth in China and abroad, the composition of the AT system, the types of the ATsystem, and the effectiveness to realize AT on construction vehicles. Then the papergives the general design, and do the detail analyzes and calculations about YB1502,which is includes the conventional calculation of the key parameters and thediscussion on optimized design to the gear, the key part of YHB1502. Finally, thepaper summarizes the research and conduct conclusions.YB1502 electric-hydraulic AT is our company's newly developed technology to meetthe market demand. It has been granted the national patent. The paper, which has fourparts, is written on the basis of the technology. The main researches and innovationsof YB1502 are as follows:a. Analyzed the development of AT technologies both in China and abroad, acquiredthe AT tech's new developing tendency, and the defined the developing position ofthe YB1502.b. Given the researches on the general design of YB1502, Acquired a patent ofmicrocomputer-controlled electric-hydraulic AT.c. Having done the analyzes, design, calculation and checking to the key parametersof YB1502 in conventional method, which includes the parameter of the amountof operating load, the strength of gear, the strength of spline, the strength of shaft,and the clutch etc.d. Having done the research on the gear, the key part of YB1502, by optimized design.
