At present, the opening and closing mechanism product at the front end of the motor train unit can be divided into a metal framework bearing mode and a glass fiber reinforced plastic bearing mode according to the bearing mode and the structure form. The commonality of these two opening and closing mechanisms is: the actuating mechanisms are connected with the cabin doors, so that the opening and closing of the cabin doors can be controlled, and the requirements of the functions of reconnection, rescue and the like of trains are met. The difference between these two opening and closing mechanisms is mainly embodied in the carrying mechanism.
1. The metal frame bearing front end opening and closing mechanism mainly comprises a cabin door, a fixed cover, a bearing mechanism (metal frame), an action mechanism and the like. The cabin door is generally made of glass fiber reinforced plastic materials, is used for coupling a front-end coupler when the cabin door is opened, and protects internal equipment when the cabin door is closed; the fixed cover is used as a non-bearing structure and is only matched with the cabin door to form a complete front-end fashionable model; the bearing structure comprises a metal framework connected among the cabin door, the fixed cover and the vehicle body datum, is used for installing the cabin door and other structures on the vehicle and simultaneously bears the weight of other components in the front end opening and closing mechanism and the air resistance when the train runs; the action mechanism is used for driving the cabin door to realize opening and closing actions.
2. The glass fiber reinforced plastic bearing front end opening and closing mechanism mainly comprises a cabin door, a fixed cover, an action mechanism and the like. The cabin door is generally made of glass fiber reinforced plastic materials, is used for coupling a front-end coupler when the cabin door is opened, and protects internal equipment when the cabin door is closed; different from a metal framework, a fixed cover of the glass fiber reinforced plastic front end opening and closing mechanism is used as a bearing structure and is used for bearing the weight of other components in the front end opening and closing mechanism and the air resistance of a train during running; the action mechanism is used for driving the cabin door to realize opening and closing actions.
For the metal framework bearing front end opening and closing mechanism, the non-bearing fixed cover and the metal framework are respectively installed with the vehicle body, two or even more than two installation standards exist, and the cabin door and the fixed cover are assembled after the fixed cover and the metal framework are installed. Due to the defects of the product structure (especially the structure of a metal framework), the fitting size between the fixed cover and the cabin door is difficult to ensure after the fixed cover is installed, and the defects of the method are that the gap between the cabin door and the fixed cover needs to be repeatedly researched and matched during installation, and the polishing and repairing work of the glass fiber reinforced plastics is complicated. For the glass fiber reinforced plastic bearing front end opening and closing mechanism, the whole body is installed with the vehicle body after the cabin door, the bearing fixed cover and the moving mechanism are researched and matched, only the only installation reference is needed between the bearing fixed cover and the vehicle body, and the repeated research and matching is not needed between the cabin door and the fixed cover.
