AUTOMOTIVE POWER TRANSMISSION WITH HYDRO AUTOMATIC POWER CONTROL AT WHEEL-TRACK PROPULSOR

摘要

FIELD: transport.SUBSTANCE: invention relates to transport machine building and can be used at tractors, self-propelled vehicles, automobiles, etc. Proposed vehicle comprises engine, gearbox, planetary transmission with extra caterpillar propulsor drive axle drive and differential with wheel propulsor drive axle drive. Differential drive elements are rigidly engaged with ring gear of planetary transmission. Extra caterpillar propulsor drive axle drive is equipped with gearing engaged with planetary gearing sun gear. Shafts of wheel propulsor and caterpillar propulsor drives are connected with fluid pumps and rpm controller of the shafts of wheel propulsor and caterpillar propulsor drives. RPM centrifugal controller is engaged with pressure lines of fluid pumps while fluid pumps are composed of displacement machines.EFFECT: higher traction and speed of the vehicle and higher efficiency of the drive.2 dwg
