IN QUEST OF THE TRANSMISSION SIZE

抄録

The paper addresses an automatic procedure to define the size (i.e. displacement) of the main units within a hydrostatic transmission for mobile vehicle applications. It is developed for one pump and one or more motor, and starts from a limited number of specifications: the rated engine power and speed, the overall power ratio, the number of motors, and the choice of fixed or variable displacement motor (s). Numerical results are given over a practical range of input data, and additional constraints are discussed which come from the vehicle locomotion.
