摘要： The present invention relates to a self propelled walker enabling a safe and a stable walker which moves with the user and does not compromise stability. The present invention of a self propelled walker provides wheels on all four contact points to the ground. The wheels are motorized and locking, so the user does not have to exert energy to propel the walker forward. The motors are connected to a touch screen control device and a motion sensor. The motion sensor detects the movement speed of the user to keep the walker in proper position while the user is walking. When being leaned on heavily the wheels lock, providing a stable support device.

摘要： A shoe brake assembly for a rail vehicle including a bogie connected with the rail vehicle. The assembly also includes a wheel having a wheel web and radially inward-facing surfaces on opposite sides of the wheel web. Also included are at least two brake pads adjacent respective radially inward-facing surfaces of the wheel and a pendulum suspension arrangement connecting the at least two brake pads to the bogie. The assembly further includes an operating device configured to move the at least two brake pads via the pendulum suspension essentially radially against respective radially inward-facing surfaces of the wheel.

摘要： A unit guide wear plate which aligns the movement of a brake beam end guide within the side frame of a railroad car truck so that the brake shoes can provide the maximum amount of force against the wheels when stopping the railroad car. The unit guide wear plate is comprised of a wear plate body, having a u-shaped cross section, a first side wall, having a first inner surface and a first outer surface; a second side wall, having a second inner surface and a second outer surface; a third side wall having a third inner surface and a third outer surface; wherein the first side wall is located such that it is attached to the third side wall opposite the second side wall; a first flange extension protruding from the first side wall and a second flange extension protruding from the second side wall; a pair of dimples arising out of the second outer surface for securing the unit guide wear plate within a railroad car side frame; a spring tang for providing a lateral force on a brake beam end guide as it lies within the unit guide wear plate body; and a first ramp extending outward from the first inner surface and a second ramp extending outward from the second inner surface, for aligning the brake beam end guide within the unit guide wear plate body.
摘要翻译：一种单元导向器耐磨板，其将制动梁端部引导件在铁路车辆卡车的侧框架内的运动对准，使得当停止铁路车辆时，制动蹄板可以向车轮提供最大量的力。单元导向磨板由具有u形横截面的耐磨板体，具有第一内表面和第一外表面的第一侧壁组成; 第二侧壁，具有第二内表面和第二外表面; 具有第三内表面和第三外表面的第三侧壁; 其中所述第一侧壁被定位成使得所述第一侧壁被附接到与所述第二侧壁相对的所述第三侧壁; 从所述第一侧壁突出的第一凸缘延伸部和从所述第二侧壁突出的第二凸缘延伸部; 从第二外表面产生的一对凹坑，用于将单元引导件耐磨板固定在铁路车辆侧框架内; 用于在制动器梁端部引导件位于单元引导件耐磨板体内时向其提供横向力的弹簧柄; 以及从所述第一内表面向外延伸的第一斜面和从所述第二内表面向外延伸的第二斜面，用于将所述制动器梁端部引导件对准所述单元引导件耐磨板主体内。
