采用双油缸加齿轮齿条同步机构的方式实现了电视转播车侧拉厢的伸出和收回动作,与以往采用传统的双电动推杆实现拉厢伸收功能的方式相比,提高了两侧驱动机构的同步性.为了提高电液系统的智能化和容错性能,设计了手动按钮、遥控器、平板电脑触摸屏三种操作方式.增加了车体倾角自动检测功能以确保拉厢在水平度较好的情况下展收,设计了压力超限超时系统自动停机功能,以保护系统.通过采用集成化的油源设计并采用EPEC控制器将电液控制系统与整车的集中控制系统连接,使平板电脑可以检测电液系统状态并操控电液系统运行,降低了系统的操控复杂性,提高了系统的自动化程度.%The two cylinders with the synchronization machine of gears and racks were used to make the carriage stretch and withdraw. Compared with the shape of two electric handspikes, this form advanced the synchronization performance. For improving the intelligent and abide errors abilities, the button, remote device and Pad all could be used to manipulate it. Furthermore, if the pressure exceeded the limit, the system will stop automatically to protect the motor. The electric-hydraulic system controller (EPEC 2024) was connected with the cen-tralized control system of the vehicle, so the pad could detect electric-hydraulic states conveniently. The complexity was decreased and the automatic degree was increased.
