The invention relates to a bogie which can increase the wheel-rail acting force, increase the adhesive force under the condition that the adhesion coefficient is not changed, meet the requirement of vehicle traction braking and enable the bogie to have good curve passing capacity and track beam joint passing capacity through the freedom degree and a hydraulic valve group in the wheel-rail acting force state. The invention relates to a guide wheel stabilizing wheel device with an adjustable wheel-rail acting force, which can meet the requirements of structural strength, rigidity, stability and the like after increasing the wheel-rail acting force, and is characterized in that the front and the back of a bogie frame are symmetrical and are inverted-U-shaped frames, and the front and the back of the inverted-U-shaped frames are connected through a cross beam; the two installation seats are matched with a shaft system at the lower end of a bogie frame through a fine adjustment structure composed of a fixed frame, a movable frame and a sliding block, the two oil cylinders are symmetrically installed between the bogie frame and the installation seats and used for adjusting the displacement of the installation seats, and the two sets of wheel sets are horizontally installed at the two ends of the installation seats and make contact with a rail beam web. The two stable wheel sets are vertically installed on the inner side of the installation base and make contact with the lower surface of the track beam upper cover plate.
本发明涉及一种既能增加轮轨作用力,在黏着系数不变条件下增加黏着力,满足车辆牵引制动的需求,又能在轮轨作用力状态下通过自由度及液压阀组让转向架具有较好曲线的通过能力和轨道梁接缝通过能力,同时又能在增加轮轨作用力后,仍然可满足结构强度、刚度、稳定性等需求的具有轮轨作用力可调的导向轮稳定轮装置,转向架构架前后对称呈倒U字型架,前后倒U字型架间采用横梁连接,两个安装座分别通过固定架、活动架及滑块构成的微调结构与转向架构架下端轴系形成配合,两个油缸对称安装在转向架构架和安装座间用于调节安装座的位移量,二套轮组水平安装在安装座两端与轨道梁腹板接触,二套稳定轮组竖直安装在安装座内侧与轨道梁上盖板下表面接触。
