    • The invention relates to a hydrostatic traveling mechanism (1) which comprises a hydraulic pump (4), a first hydraulic engine (8) that is linked with the hydraulic pump (4) via a hydraulic work circuit (2) and that drives a first drive train (17). The traveling mechanism further comprises a second hydraulic engine (10) that is linked with the hydraulic pump (4) via a hydraulic work circuit (2) and that drives a second drive train (19). The inventive traveling mechanism is also provided with a third hydraulic engine (23) that is coupled with the first drive train (17) and a fourth hydraulic engine (24) that is coupled with the second drive train (19). The third hydraulic engine (23) and the fourth hydraulic engine (24) are linked with each other via a hydraulic secondary circuit (3) that is independent of the work circuit (2).

    • The invention concerns a control for a hydrostatic power train (1) comprising a hydraulic pump (2) which is connected, via a first main pipe and a second main pipe (7, 8), to a first hydromotor unit (5, 5′) driving a front axle and to a second hydromotor unit (6, 6′) driving a rear axle. The first and second hydromotor units (5, 5′, 6, 6′) can be adjusted in terms of their displacement via a first and a second variation device (30, 31, 30′, 31′) respectively. A direction of travel is defined as forward movement (F) or reverse movement (R) by a position of an operating lever (37). The first and the second variation devices (30, 31, 30′, 31′) are controlled by a control valve (32, 32′) which takes up a first control position upon a forward movement (F) determined by the position of the operating lever (37) and which takes up a second control position upon reverse movement (R) determined by the operating lever (37). In the first control position, the first variation device (30, 30′) is controlled such that the first motor unit (5, 5′) is adjusted for a smaller displacement and, in the second control position, the second variation device (31, 31′) is controlled such that the second motor unit (6, 6) is adjusted for a smaller displacement.
    • 本发明涉及一种包括液压泵(2)的液压动力传动系(1)的控制装置,其经由第一主管和第二主管(7,8)连接到第一液压马达单元(5,5'), )驱动前轴和驱动后轴的第二液压马达单元(6,6')。 第一和第二液压马达单元(5,5',6,6')可以分别经由第一和第二变速装置(30,31,30',31')的位移来调节。 行进方向由操作杆(37)的位置定义为向前运动(F)或反向运动(R)。 第一和第二变速装置(30,31,30',31')由控制阀(32,32')控制,该控制阀在由前进运动(F)确定的向前运动(F)处占据第一控制位置 操作杆(37),并且在由操作杆(37)确定的反向移动(R)时占据第二控制位置。 在第一控制位置,第一变速装置(30,30')被控制成使得第一电动机单元(5,5')被调整为较小的位移,而在第二控制位置中,第二变速装置(31 ,31')被控制,使得第二电动机单元(6,6)被调整为较小的位移。
