Embodiment 1

[0041] Such as figure 1 As shown, a left front cover 1 and a right front cover 2 are symmetrically arranged on the head of the rail vehicle driver's cab along the longitudinal centerline of the car body, and the left front cover 1 and the right front cover 2 are arc-shaped. The shape is consistent to ensure that the running resistance does not increase when the vehicle is running. The left front cover 1 and the right front cover 2 are connected to the power mechanism 3. The left front cover 1 and the right front cover 2 are opened or closed to both sides under the drive of the power mechanism 3. During the opening process Among them, the left front cover 1 and the right front cover 2 will avoid other parts in the car, and the power mechanism 3 is fixed on the upper plane of the vehicle underframe. Both the left front cover 1 and the right front cover 2 are made of glass fiber reinforced plastics, which can not only ensure their strength and rigidity, but also reduce the weight...

Embodiment 2

[0073] The difference from Embodiment 1 is that the telescopic end of the opening and closing cylinder 5 is connected with the left first connecting rod 8 and the right first connecting rod 9 through a push rod (not shown in the figure), and the push rod is divided into a fixed section and a rotating section Two sections, the telescopic link of opening and closing cylinder 5 is fixedly connected with the fixed section, and the rotating section is two connected with the first left connecting rod 8 and the first right connecting rod 9 respectively, and the fixed section and the rotating section are rotatably connected by a rotating shaft. When the telescopic rod of the opening and closing cylinder 5 stretches forward, the push rod pushes the left first connecting rod 8 and the right first connecting rod 9 forward, and the left first connecting rod 8 and the right first connecting rod 9 interact with each other under the action of thrust. Close up, the four-bar linkage is elongate...

Abstract

The invention relates to a railway vehicle front cover opening and closing mechanism and a design method thereof. The railway vehicle front cover opening and closing mechanism comprises a left front cover and a right front cover arranged symmetrically, and a power mechanism for driving the left and right front covers to open and close; the power mechanism comprises a mounting base, an opening / closing air cylinder, a left four-bar linkage and a right four-bar linkage, wherein the opening / closing air cylinder is fixed on the mounting base, the mounting base is fixed on an underframe, the left and right linkages are respectively composed of four continuous linkages, the front end parts of the left and right linkages are fixedly connected with the left front cover and right front cover respectively, the initial points of two first linkages at left and right are jointly hinged to a stationary shaft, the stationary shaft is fixed on the mounting base, and connection points of two second linkages at left and right and two third linkages at left and right are mutually hinged to each other in a crossing manner. According to the railway vehicle front cover opening and closing mechanism, by using the simple four-bar linkages, the left and right front covers can be opened according to specific motion rails to bypass other barriers, the motion is completed in one step, the complexity of the opening-closing device is effectively reduced, the cost of the device is reduced, the structure is simple and the function is practical.

Description

technical field [0001] The invention relates to a front cover of a rail vehicle head, in particular to a rail vehicle front cover opening and closing mechanism and a design method, and belongs to the technical field of rail vehicle manufacturing. Background technique [0002] When the rail vehicle is connected or rescued, it is necessary to connect the coupler. In order to meet the requirements of the vehicle connection, the front end of the rail vehicle head adopts a split-type automatic opening and closing front cover structure. The front cover is driven by the opening and closing mechanism. When the vehicle is running normally, the front cover is closed, and when needed, the front cover is opened left and right to leave the necessary space for the coupler to hang, and the coupler is automatically unlocked and extended and connected to realize reconnection or pairing between trains Rescue the broken down train. [0003] At present, the opening and closing device of the fr...
