The utility model discloses a single-row double-pole type hydraulic mechanical continuously variable transmission. The system is characterized by comprising a power input system, a hydraulic pump control motor speed regulation system, a confluence planet row mechanism, a clutch switching mechanism, a hydraulic mechanical retreating section mechanism and a rear axle output mechanism. The power input shaft (23) is synchronously and coaxially provided with a single-row planetary gear set gear ring (6), a planet carrier (9) and a sun gear (20), the single-row planetary gear set planet carrier (9)is synchronously and coaxially provided with a duplex planet gear (7), and power is converged and transmitted backwards. The retreating planet wheel (10) is meshed with a gear on the hollow intermediate gear shaft (17); and the hollow intermediate gear shaft (17) is nested on the intermediate shaft (19). The transmission adopts a single-row bipolar planet row and is small in transverse size. The advantages of high efficie
