    • A wheel suspension for mounting in a chassis of a working machine, said wheel suspension comprising a drive axle, a wheel and a hub device, said hub device comprising a first hub unit, which is stationary in the axial direction of the wheel suspension and connected to said axle, and a second hub unit, which is connected to the wheel, said second hub unit being adapted to be displaced in the axial direction of the wheel suspension relative to the first hub unit for altering the axial position of the wheel relative to the first hub unit, wherein the hub device also comprises an actuator for controlled actuation of the second hub unit to bring about said displacement. According to the invention, the actuator comprises a hydraulic cylinder (51), which is arranged inside a protecting and supporting means (52) for absorbing forces or force components in the radial direction of the hydraulic cylinder, said protecting and supporting means comprising a first supporting sleeve (53), which is adapted to be connected to the chassis, and a second supporting sleeve (54), which is directly or indirectly connected to the second hub unit, said supporting sleeves being telescopically arranged within each other for enabling a telescopic movement between the supporting sleeves.
    • 一种用于安装在工作机的机架中的车轮悬架,所述车轮悬架包括驱动轴,车轮和轮毂装置,所述轮毂装置包括第一轮毂单元,所述第一轮毂单元在所述车轮悬架的轴向方向上是静止的并且连接 所述第二轮毂单元连接到所述车轮,所述第二轮毂单元适于相对于所述第一轮毂单元在所述车轮悬架的轴向方向上移位,以改变所述车轮相对于所述车轮的轴向位置 所述第一轮毂单元,其中所述轮毂装置还包括用于所述第二轮毂单元的受控致动以实现所述位移的致动器。 根据本发明,致动器包括液压缸(51),该液压缸(51)布置在保护和支撑装置(52)的内部,用于沿液压缸的径向方向吸收力或力部件,所述保护和支撑装置包括第一 支撑套筒(53),其适于连接到底盘;以及第二支撑套筒(54),其直接或间接地连接到第二轮毂单元,所述支撑套筒可伸缩地布置在彼此中,以实现伸缩 支撑套之间的运动。
