Abstract

Abstract: The appropriate planetary gear differential train and hydrostatic units are chosen to constitute the hydro-mechanical continuously variable transmission to give the transmissive schemes of HMCVT，which suits the transmission of vehicle． The transmission characteristics of rotary speed ratio，power ratio and rotary torque ratio of HMCVT of the non-road separated torque ratio-fixed speed ratio with the range of ( 3 + 1) are analyzed． The results show that: the scheme can be better adapt to the hydraulic mechanical transmission requirements of off-road vehicle．

Key words: hydro-mechanical continuously variable transmission, drive scheme, transmission characteristics
