Description

[Detailed Description of the Invention] The present invention relates to a wing of a sliding body of a pantograph.

The sliding body boat of a conventional pantograph cannot follow the rapid movement of the vehicle as the vehicle speeds up, and the power collection decreases. This is because the elasticity of the springs in the support system causes a delay in responding to boat vibrations by about 1/10 to 1/1000 seconds.

Similarly, as shown in FIG. 1, in the structural form of the conventional pantograph sliding body boat 1, pressure resistance 2 and turbulence resistance 3 of the fluid (air) on the forward surface during high-speed operation are caused by the support system of the boat 1. The elasticity of the spring exceeds the elasticity of the spring, and the vertical movement of the boat 1 causes vibration 4, which leads to separation from the line and deterioration of tracking performance, resulting in a decrease in power collection. This is because in the structural form of the boat 1, the higher the speed of the vehicle, the more the suitability of fluid dynamics is gradually lost.

The loss of track and deterioration of tracking performance of the boat 1 of the sliding body of a conventional pantograph is due to the negative synergistic effect of the delayed response of the spring of the support system and the resistance of fluid (air) 2 and 3 as the vehicle speeds up. This is due to the effect of

The present invention incorporates wings into the sliding body of the pantograph, and in response to fluid dynamics, the higher the speed of the vehicle, the more it prevents derailment and improves tracking performance, increasing power collection. The wing to be installed is a laminar flow wing, and the lift force is always applied in one vector, supporting the elasticity of the spring in the support system and landing on the line.

The wings of the sliding body of the pantograph of the present invention will be explained with reference to FIG.

The wing 5 is a laminar flow wing with left and right sides being the same in terms of fluid dynamics. The wing 5 has a sliding plate 6 at the top and a rotating flap 7 of a high-lift system at the bottom. Wing 5 when driving at high speed
is attached to the overhead wire by the combination of the lifting force 9 due to the action of the fluid 8 and the lifting force 10 of the flap 7 of the high-lift system. The fluid 8 acts more steadily on the wings 5 and on the flaps 7 of the high-lift system, the higher the vehicle speed. The flap 7 of the high-lift system pivots counter to the direction of travel of the vehicle and the fluid 8
A lift force of 10 is obtained by the action of . The angle of attack is controlled by a stick 11.

The higher the vehicle speed, the more the lifting forces 9 and 10 are affected by the stable action of the fluid 8, and always have one vector, assisting the elasticity of the support system,
Land wing 5.

As shown in FIG. 3, a spring 13 is interposed between the frame 12 and the wing 5, and the elasticity of the spring 13 and the combined force of the lift forces 9 and 10 are used to attach the wire.
The current is applied through the cable 14.

As shown in Figure 3, wing 5 of flap 7
To install it, lightly hoist it with an arm or the like on the inside of the frame 12 at the bottom of the wing 5, and do not tighten the duct part due to the pendulum movement. Similarly, as shown in FIG. 3, a spring 13 interposed between the wing 5 and the frame 12
is a convention spring of stacked leaf springs, which pushes up the wing 5 with the lifting forces 9 and 10 of one vector to make it land on the line.

The present invention employs laminar airfoil wings 5 for the sliding body of the pantograph, and in response to the fluid dynamics of the wings 5, the higher the speed of the vehicle, the more the lift forces 9 and 10 of one vector are combined, and the support is increased. It supports the elasticity of the spring 13 of the system and connects the wire.

This prevents disconnection and improves followability, and increases the power collection of the pantograph.
