Methods Rats aging 4 weeks were immobilized by limb-tail fixation for 2 and 4 weeks respectively, and then the wet weight, gray weight, bone mineral density of femurs and tibiae were measured, the histopathological and histomorphological parameters also were detected, which were used to evaluate the effect of immobilization on bone content and bone structure of femurs and tibiae in growing rats. The VDR expression of femurs and tibiae in the growing rats was evaluated by immunohistochemistry and image analysis.

根据L-B型组合式制动梁的结构特点，运用I-DEAS软件建立基于接触的L-B型制动梁有限元模型，并计算了制动梁在不同工况下的应力分布，计算结果表明应力集中主要发生在闸瓦托滑块根部，这与实际运行中出现的故障较为吻合，为制动梁的改进设计和结构优化提供了依据。

The specific method is: first host of the brake rod to remove the trailer brakes to adjust the various parts, when the trailer brakes until the wheels with the ground so far appeared prints hysteresis drag, and then host the brake rod lever arm with pedal connections, and adjust the brake connecting rod connecting the host length, until the brake unit, all wheels have friction with the ground traces of the adjustment shall be qualified.

具体方法是：先把主机的制动连杆摘掉，对挂车制动装置的各个部位进行调整，直至刹车时挂车的车轮与地面出现拖滞印痕为止，然后再把主机的制动连杆与踏板的杠杆臂连接好，调整主机制动连杆的连接长度，直到机组刹车时，所有的车轮与地面有摩擦痕迹，即为调整合格。

When the hydraulic pressure power supply stops or controls the solenoid valve opens, in driving pliers' pressure oil pressure vanishing, the piston under the precompression brake block spring's function rapidly promotes, affects on the friction liner and presses to is applied the brake the body, simultaneously the driven pliers in the driving pliers and under connecting bolt's function, lead through the glide guide pillar's function rub the liner to press to are applied the brake the sleeve to become the brake.

当液压动力源停止或控制电磁阀打开时，主动钳内的压力油压力消失，活塞在预压的制动弹簧的作用下迅速推出，作用在摩擦衬垫上并压向被制动体，同时从动钳在主动钳和连接螺栓的作用下，通过滑动导柱的作用带动摩擦衬垫压向被制动体完成制动。
