Damping hinge for movable side windows of train-set driver cabs

Abstract

The invention relates to a damping hinge for movable side windows of train-set driver cabs. The damping hinge comprises a movable seat, a fixed seat and a rotary shaft; the movable seat is connected with the fixed seat through the rotary shaft, and a damping part mounting hole is formed in the movable seat and transversely communicates with a movable seat rotary shaft mounting hole in the movableseat; an adjusting screw, a spring and steel balls constitute a damping device of the hinge to be arranged in the damping part mounting hole; and a rotary shaft half-edge threaded hole is formed in the upper end of the rotary shaft, a fixed seat half-edge threaded hole matched with the rotary shaft half-edge threaded hole is formed in a fixed seat rotary mounting hole, and after tightening throughset screws, the set screws are seized for fixing in the half-edge threaded hole in the rotary shaft and the half-edge threaded hole in the fixed seat. The damping hinge is high in structural strength, firm in connection and adjustable in damping magnitude.

Description

technical field [0001] The invention relates to the field of rail transit driver's cab side windows, in particular to a damped hinge for a movable side window of an EMU driver's cab. Background technique [0002] If the traditional hinge is used for the left and right movable side windows of the driver's cab of the 160 kilometers per hour power concentrated EMU, especially for the hinged lever type supporting movable side windows of the movable window, the following problems will occur when the weight reaches more than 20 kg : 1. The structural strength does not meet the requirements, and it is easy to deform; 2. The internal connection accuracy does not meet the requirements, causing the movable window to vibrate and fall during the movement; 3. Only bolts are used to connect the fixed frame and the movable frame of the side window. It cannot meet the safety requirements of locomotives under severe impact conditions; 4. Without damping function, it cannot meet the requireme...

Problems solved by technology

[0002] If the traditional hinge is used for the left and right movable side windows of the driver's cab of the 160 kilometers per hour power concentrated EMU, especially for the hinged lever type supporting movable side windows of the movable window, the following problems will occur when the weight reaches more than 20 kg : 1. The structural strength does not meet the requirements, and it is easy to deform; 2. The internal connection accuracy does not meet the requirements, causing the movable window to vibrate and fall during the movement; 3. Only bolts are used to connect the fixed frame and the movable frame of the side window. It cannot meet the safety requirements of locomotives under severe impact conditions; 4. Without damping function, it cannot meet the requirements of the movable side window to stop at any position; 5. It cannot meet the requirements of frequent use and long working life (more than 50,000 times) ; 6. It cannot meet the requirement that the opening angle of the side window is set at 90 degrees; therefore, according to these characteristics of the traditional hinge, it has been confirmed that it cannot meet the functional requirements of the existing motor vehicle side window
