    • A vehicle having a load support body (5), and a pair of front ground engaging wheels (1, 2) and a pair of rear ground engaging wheels (3, 4) connected to the body (5) to support same and each wheel being displaceable relative to the body in a generally vertical direction. A double acting fluid ram interconnected between each wheel (1, 2, 3, 4) and the body (5) each ram including first (17a, 18a)(13a, 14a) and second (17b, 18b)(13b, 14b) fluid filled chambers on opposite sides of the ram piston, said first and second chambers oppositely varying in volume in response to vertical movement between the respective wheels and the body. Respective first fluid communicating conduits (10, 10a) connecting said first chambers (17a, 18a)(13a, 14a) of the front and rear wheels (1, 2, 3, 4) on the same side of the vehicle to provide respective first individual fluid circuits between the interconnected first chambers (17a, 18a)(13a, 14a), and respective second fluid communicating conduits (8, 8a) connecting the second chambers (17b, 18b)(13b, 14b) of the front and rear wheels (1, 2, 3, 4) on the same side of the vehicle to provide respective second individual fluid circuits between interconnected second (17b, 18b)(13b, 14b) chambers. Respective further conduits (35, 36) are provided interconnecting the first fluid circuit (10, 10a) on each side of the vehicle to the respective second fluid circuit (8, 8a) on the opposite side of the vehicle. The two front wheels (1, 2) of the vehicle are connected to the body by respective additional fluid rams (11, 12) defining respective third fluid chambers. The third fluid chambers being interconnected by a third conduit (7). Each of the conduits (10, 10a, 7) and preferably conduits (8 and 8a) have an accumulator (21, 22, 25, 26,...) or other resilience inducing device to accommodate fluid displaced from the rams in the circuit, and provide resilience to the system.
    • 具有负载支撑体(5)的车辆和连接到主体(5)上的一对前地面接合轮(1,2)和一对后地面接合轮(3,4)以支撑其并且每个车轮 相对于身体在大致垂直的方向上可移动。 在每个车轮(1,2,3,4)和主体(5)之间互连的双作用液压油缸,每个压头包括第一(17a,18a)(13a,14a)和第二(17b,18b)(13b,14b) 在柱塞活塞的相对侧上的流体填充腔室,所述第一和第二腔室响应于各个轮子和主体之间的垂直运动而相反地变化。 将前轮和后轮(1,2,3,4)的第一室(17a,18a)(13a,14a)连接在车辆的同一侧上的相应的第一流体连通管道(10,10a),以提供相应的第一 在互连的第一腔室(17a,18a)(13a,14a)之间的各个流体回路和连接前轮和后轮的第二腔室(17b,18b)(13b,14b)的各自的第二流体连通管道(8,8a) (1,2,3,4)在车辆的同一侧,以在相互连接的第二(17b,18b)(13b,14b)室之间提供相应的第二单独流体回路。 提供了相应的另外的管道(35,36),其将车辆每一侧上的第一流体回路(10,10a)互连到车辆相对侧上的相应的第二流体回路(8,8a)。 车辆的两个前轮(1,2)通过限定相应的第三流体室的相应附加流体柱塞(11,12)连接到主体。 第三流体室通过第三导管(7)相互连接。 每个导管(10,10a,7)以及优选的导管(8和8a)具有一个蓄能器(21,22,25,26,...)或其它回弹诱导装置,以容纳从电路中的柱塞排出的流体 ,并为系统提供弹性。

    • A vehicle having a suspension comprising a double acting ram (13, 14, 17, 18) connecting each wheel (1, 2, 3, 4) independently to the body (5) of the vehicle, each ram (13, 14, 17, 18) having respective first (13a, 14a, 17a, 18a) and second (13b, 14b, 17b, 18b) chambers that vary in volume as the wheels move relative to the vehicle body (5). Each front wheel ram (13, 18) is connected to the diagonally opposite rear wheel ram (14, 17) by a respective pair of conduits (8, 10) and (8a, 10a) arranged so the first chamber (13a, 18a) of one wheel is connected to the second chamber (14b, 17b) of the other wheel. Each first and second chamber and the conduits connected thereto are filled with fluid and independent of external fluid and pressure sources. Diagonal interconnection of the front and rear rams minimizes roll movement in a lateral direction and pitch movement in the longitudinal direction of the vehicle.
    • 一种具有悬架的车辆,包括将每个车轮(1,2,3,4)独立于车辆本体(5)连接的双作用柱塞(13,14,17,18),每个压头(13,14,17,18) ,18)具有随着车轮相对于车身(5)移动而具有相应的第一(13a,14a,17a,18a)和第二(13b,14b,17b,18b)室。 每个前轮压头(13,18)通过相应的一对导管(8,10)和(8a,10a)连接到对角相对的后轮压头(14,17),并且第一腔室(13a,18a) 一个车轮的另一个轮的第二室(14b,17b)连接到另一个车轮的第二室。 每个第一和第二室和连接到其上的导管填充有流体并且独立于外部流体和压力源。 前后凸轮的对角线互连最大程度地减小了横向上的滚动运动和在车辆纵向方向上的俯仰运动。
