摘要： A stepless speed change gear for a vehicle enabling smooth starting of the vehicle in quick response to a stepped-on accelerator. This speed change gear intends to eliminate an undesirable starting action such as delay in response and subsequent abrupt starting specific to stepless speed change gear in general for low-speed and high-speed vehicles. For the above purpose, the stepless speed change gear is provided with a variable speed hydraulic transmission system comprising a variable volume type hydraulic pump/motor acting as a pump connected to another hydraulic pump/motor as a motor and, further, with an internal spool to vary a displacement volume of the hydraulic pump/motor acting as a pump, control piston, throttle changeover valve, circuit for detecting pressure difference in the hydraulic transmission system, potentiometer, and duty control valve. The spool undergoes negative feedback control by the duty control valve so that an effective pressure difference detected by a pressure difference detecting circuit may be kept at a set pressure corresponding to an angle of accelerator detected by accelerator angle detecting means.
