During the running of the railway vehicle, an active load received from the wheel to the rail, in the structure sandwiched by the left and right of the claw received from the bottom of the rail, the effect also has rails of the rail gauge of the deviation of loss and clothes Susumutome (slip) fastening device of

摘要

PROBLEM TO BE SOLVED: To provide a fastening device between a rail and a sleeper, the device that is structured to receive a live load to the rail received from a wheel by the bottom of the rail and to sandwich the rail with a left and a right claws in the traveling of a railway vehicle, is provided with both of the reduction effect of deviation of a rail gauge and the effect of creeping stopper (anti-slip), and in which, conventionally, when the rail is fixed to the sleeper by using a spring-type fastening device, the rail is fixed while being pressed down to the sleeper by a steel spring, and therefore, the deviation may gradually be caused in the rail gauge when the railway vehicle passes the rail frequently every hour and every day.;SOLUTION: A fastening device of the present invention is structured to directly receive a load of a rail, even if the rail is fixed to the sleeper like a conventional fastening device. Accordingly, a live load or a wheel load of the vehicle via the rail is directly transmitted from a wheel to the rail, from the rail to the fastening device, and also, from the fastening device to the sleeper, and the device is structured to conversely use the friction generated in each place. Consequently, the friction of the ground plane of each place is used as a supporting force, and the pitching and rolling motion caused by the passage of the vehicle is moderated and transmitted, and thereby the device can be provided and used as services for reducing and preventing the deviation of the gauge.;COPYRIGHT: (C)2015,JPO&INPIT
