Problems solved by technology

[0003] However, the emergency unlocking device currently used in the train door system has a complex structure and takes up space and is prone to jamming when unlocking, resulting in low reliability. Moreover, the current emergency unlocking device is of non-standard design and its manufacturing cost is high.
The structure of the electromagnetic clutch assembly has certain defects in terms of installation space, torque usage and train system applicability, so it cannot meet the requirements of the emergency unlocking device

Abstract

The invention discloses a clutch assembly which comprises a cam as a driving shaft and a hollow support seat, the hollow interior of the support seat is provided with a transmission shaft and a bidirectional overrun clutch with a driving outer ring and a driven inner ring, and the transmission shaft penetrates through the bidirectional overrun clutch and is fixedly connected with the inner ring ofthe bidirectional overrun clutch; the cam is arranged on one side of the support seat and is fixedly connected with an outer ring of a one-way clutch, an inner ring of the one-way clutch is fixedly connected with a connecting flange, and the connecting flange is fixedly connected with the outer ring of the bidirectional overrun clutch. According to the clutch assembly, when the cam as the drivingshaft does not move, the inner ring, as a driven shaft, of the bidirectional overrun clutch is capable of rotating freely in both directions, and the clutch assembly is applied to various needed occasions.

Description

technical field [0001] The invention belongs to the field of transmission systems, and in particular relates to a clutch assembly, in particular to a device which can be used in a train transmission system for emergency unlocking. Background technique [0002] With the rapid development of urban rail transit in my country, the main goal of urban rail vehicles is to quickly and safely transport a large number of passengers. The train door system is an important part of the rail vehicle, which directly affects the normal operation of the vehicle and the safety of passengers; emergency unlocking The device is one of the two key cores in the train door system. When an emergency occurs during the operation of the equipment (such as fire, power supply failure, control system failure, signal system failure, etc.), it is necessary to open the train door channel through the emergency unlocking device. To evacuate passengers to avoid major accidents, the emergency unlocking device is th...
