The invention discloses a tractor driven by a hydraulic motor. A wheel seat is fixed below a tractor frame, and a bearing wheel is fixed on the wheel seat and corresponds to a rail; a driving wheel isfurther arranged, and the driving wheel corresponds to the pin row; the driving wheel is connected with the output end of the planetary reducer, the input end of the planetary reducer is connected with the output end of the hydraulic motor, the hydraulic motor is driven by the oil pump, and the oil pump is driven by the motor to rotate. The speed reducer has the advantages that the oil pump is driven by the motor, the hydraulic motor is driven by the oil pump, the hydraulic motor drives the driving wheel through the planetary speed reducer, and the planetary speed reducer has a large rotatingspeed ratio, so that the size of the speed reducer is reduced; and the driving wheel is directly arranged on the outer side of the outer circle of the planetary reducer, so that the occupied space isreduced.
本发明公开一种液压马达驱动的牵引车,车架的下方固定有轮座,承重轮固定在所述轮座上,承重轮与轨道对应;还设置驱动轮,所述驱动轮与销排对应;所述驱动轮与行星减速器的输出端连接,所述行星减速器的输入端与液压马达的输出端连接,所述液压马达由油泵驱动,所述油泵由电机驱动旋转。本发明的优点是:采用了电机驱动油泵,油泵驱动液压马达,液压马达通过行星减速器驱动驱动轮的形式,由于行星减速器具有较大的转速比,因此,减小了减速器的尺寸;而驱动轮直接设置在行星减速器的外圆外侧,更是减小了空间占用尺寸。
