The present invention is related to a hydrostatic drive system (1) for vehicles. This system (1) comprises a hydrostatic transmission unit comprising a hydraulic motor (2) provided with a containmentbody (3) and a drive shaft (4) rotationally supported around a primary axis (A) inside of the containment body (3) and provided with a terminal section (4a) protruding to the outside of the body itself. The system (1) further comprises an axle (6) comprising a housing case (7) for a differential device (8) for the transmission of the drive torque to two half-axles (9) supporting respective wheelsand rotating around a secondary axis (B) transverse to the primary axis (A). The differential device (8) is provided with a toothed conical drive ring gear (11) in rotation about the secondary axis (B), which is operationally associated with the drive shaft (4) for the transmission of the drive torque through a coupling member (12). The distinctive characteristic or the invention consists of the fact that this coupling member comprises a conical pinion (12) rigidly associated in rotation about the primary axis (A) with the drive shaft (4) and directly geared with the ring gear (11), the pinion(12) being positioned along the terminal section (4a) of the drive shaft (4).

    本发明涉及一种用于车辆的静压驱动系统(1)。该系统(1)包括静压传动单元,该静压传动单元包括液压马达(2),该液压马达设有容纳体(3)和驱动轴(4),该驱动轴绕初级轴线(A)旋转地支承在容纳体(3)内部,并且设有突出到容纳体本身的外部的终端部分(4a)。系统(1)还包括车桥(6),该车桥(6)包括用于差动装置(8)的壳体外壳(7),该差动装置用于将驱动扭矩传递到两个半桥(9),这两个半桥承载相应的轮子并绕横向于初级轴线(A)的次级轴线(B)旋转。差动装置(8)设有绕次级轴线(B)旋转的带齿的锥形驱动齿圈(11),该锥形驱动齿圈与驱动轴(4)操作地相关联,用于通过联接构件(12)传递驱动扭矩。本发明的独特特征包括以下事实:该联接构件包括锥形小齿轮(12),该锥形小齿轮(12)围绕初级轴线(A)旋转地与驱动轴(4)刚性地相关联,并且直接与齿圈(11)齿轮连接,小齿轮(12)沿着驱动轴(4)的终端部分(4a)定位。
