Embodiment Construction

[0012] Examples, as attached figure 1 As shown, a safety variable-length train set includes a safety detection locomotive 1 , a safety variable-length control system 2 , a traction locomotive 3 , and a carriage 4 .

[0013] The total length from the front end of the safety detection locomotive 1 to the rear end of the compartment 4 is L, the distance from the rear end of the safety detection locomotive 1 to the front end of the traction locomotive 3 is S, the constant forward speed of the safety variable length train set is V, and the safety variable length train The commonly used acceleration for group braking is a, the emergency braking of the traction locomotive 3 and compartment 4 is aQ, and the immediate speed of traction locomotive 3 and compartment 4 is VQ. The emergency braking of the safety detection head 1 is aA, and the immediate forward speed of the safety detection head 1 is VA.

[0014] The total length L of the train set in the embodiment changes according to t...

Abstract

The invention discloses a safety lengthening train set, and the train set comprises a safety detection headstock 1, a safety lengthening control system 2, a traction headstock 3 and a carriage 4, and the total length of the train set from the headstock to the tailstock is varied according to the advancing speed. If an abnormal situation is discovered by the safety detection headstock 1, an ultralarge deceleration is adopted until the train set is stopped, the length of the safety lengthening train set is rapidly reduced, emergency brake is started for the traction headstock 3 and the carriage 4, so that the speed of the traction headstock and the carriage 4 is reduced to zero before the length of the safety lengthening train set is changed to a set minimal value, so that the safety running of the traction headstock and the carriage 4 can be guaranteed.

Description

technical field [0001] The invention belongs to ground rail vehicles, in particular to a safe variable-length train set. Background technique [0002] The train currently in operation is composed of a traction locomotive and a carriage, and the total length from the locomotive to the rear is invariable. The forward speed is controlled by the driver. The observation range of the abnormal situation ahead does not match the speed of the train. It is difficult to ensure the safety of the train moving forward, especially at high speed, under abnormal circumstances. Such as the 2011-07-23 Yongwen train accident is a typical example. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a safe variable-length train set, the total length of the train set from the front to the rear varies according to the forward speed, which can ensure the safe operation of the traction locomotive 3 and the carriage 4 . [0004] In order t...
