Problems solved by technology

When the pantograph runs in different directions, the aerodynamic force may be a lifting force or a downward force. In fact, it cannot meet the current needs of the vehicle speed above 100km / h, and has no use value.

Abstract

The invention discloses a high-speed pantograph head with double contact strips. The high-speed pantograph head comprises an upper top pipe (1), sleeves (2), two pantograph horns (3) and two spring supports (4); two sets of spring pieces are symmetrically arranged at the two sides of each spring support (4), each set of spring pieces is composed of the upper spring piece (5) and the lower spring piece (6) in parallel, and the ends of the spring pieces in each set are connected with one contact strip support (7); every two contact strip supports (7) located at the same side of the upper top plate (1) are provided with one contact strip (8), and namely the two contact strips (8) are symmetrically arranged at the two sides of the upper top plate (1). Several sets of simple spring pieces installed symmetrically are used for replacing an original complex spring hanging system, the high-speed pantograph head has the advantages of being light and good in aerodynamics performance. The two contact strips are used, and lighter contact strips can be used, and the following performance of the pantograph can be greatly improved.

Description

technical field [0001] The invention relates to a high-speed pantograph bow head, in particular to a double-slide high-speed pantograph bow head. Background technique [0002] The pantograph is the equipment used by the catenary to supply power to the EMU or electric locomotive. Since the EMU or electric locomotive is in contact with the catenary in motion, the requirements for the dynamic characteristics of the pantograph are very high. The bow head is the key part of the pantograph. The requirements of the pantograph for the bow head are simple structure, light weight, small size and good aerodynamic characteristics. At present, there are many kinds of high-speed pantographs in the world, and there are also many kinds of high-speed pantograph heads. However, the bow spring suspension system is generally complex in structure, large in size, heavy in weight, and its aerodynamic performance is also greatly affected. Li Fengliang once invented a high-speed pantograph bow (p...
