Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a suspension device for a drawing line of a driving motor of an electric vehicle.

Generally, the drive motor of an electric car is mounted on the locomotive's bogie, and its Hiji line is connected to the distribution line of the power supply device with a wiring terminal block installed under the floor of the car body, but when the locomotive is running In order to prevent excessive external force from being applied to the marking line due to changes in the relative position between the car body and the bogie in the left-right direction that sometimes occur, the part of the Hiji Line located between the car body and the bogie is suspended under the floor of the car body. It is hung so that it can be moved freely.

However, in the conventional suspension device, a receiving member is installed under the floor of the vehicle body at a predetermined interval, and both ends of a horizontal bar that penetrates the hollow part of the hollow body protrude greatly from the hollow part are attached to the receiving member. is fixed using a nut or the like, and a wire seat holding a lead wire is supported via chains at both ends of the lower circumference of the hollow body 5, and sliding along the horizontal bar of the hollow body and The swinging nature of the chain allows the Hiji Line to be moved freely.

However, with such a configuration, the horizontal bar supporting the hollow body must be attached to and removed from the receiving member each time the bogie is extracted from the vehicle body or assembled into the vehicle body.

However, when attaching and detaching the horizontal bar, a part of the body must be inserted into the narrow gap between the car body and the truck, and the work must be done upwards, which is not only inefficient but also undesirable in terms of injury prevention.

The present invention is an attempt to easily solve the above-mentioned problems of the conventional suspension device for the Hiji Line electric vehicle drive motor.

The present invention will be explained according to the embodiments shown in FIGS. 1 to 4.

In FIG. 1, reference numeral 1 denotes a vehicle body, and the upper end of a receiving member 2 is fixed under the floor of the vehicle body 1 at a predetermined distance.

Reference numeral 3 denotes a horizontal bar that is loosely fitted into the hollow part of the hollow body 5 and passes through it, and the horizontal bar 3 is set to a length such that both ends thereof largely protrude from the hollow part.

Both ends of the horizontal bar 3 are fixed to the lower part of the receiving member 2 using nuts 4 or the like.

An opening 1 cut out around the circumference along the longitudinal side surface of the hollow body 5
form 0.

The interval between the openings 10 is sufficiently larger than the diameter of the horizontal bar 3.

A predetermined outer periphery of the hollow body 5 is connected to a spring seat 12 via a connecting member 11.
connected to.

The distal end surface of the spring seat 12 is located slightly behind the corresponding opening 10, and after forming a long parallel section in the direction of the distal end, it is raised up to reach the rear parallel section 12a.

The rear end portion of the leaf spring 13 is fixed onto the rear end parallel portion 12a of the spring seat 12 using a rivet 14.

The leaf spring 13 and the parallel end portion of the spring seat 12 are parallel to each other.

The tip of the leaf spring 13 is bent upward at a nearly right angle and then bent outward at a right angle so that the corresponding opening can be closed.

The outward bent portion is designated as 13a. Both ends of the lower surface layer of the hollow body 5 support a wire seat 7 via chains 6.

Reference numeral 8 designates a holding plate, which has a concave portion in the center and a flat surface at both ends. After fitting a predetermined number of sunrise wires 15 into the concave portions, both ends of the holding plate 8 and opposite ends of the wire seat 7 are connected with bolts 9. By tightening with , the sunrise wire 15 is held between the wire seat 7 and the holding plate 8 .

In such a configuration, it is assumed that both ends of the horizontal bar 3 are fixed to the receiving member 2.

In order to fit the horizontal bar 3 into the hollow part of the hollow body 5 in this state,
After abutting the corresponding lower periphery of the horizontal bar against the outward bent portion 13a, the spring seat 12 is pushed upward and at the same time the leaf spring 13
If the tip of the plate spring 13 is pressed, the opening that has been closed until now at the tip of the leaf spring 13 will be opened, and the horizontal bar 3 can be fitted into the hollow portion through the opening.

When the push-up blade and the pressure on the spring seat 12 and the leaf spring 13 are released, they return to their original state and the corresponding opening is closed by the leaf spring 13.

In order to remove the hollow body 5 from the horizontal bar 3, a pushing force and a pressing force are applied to the spring seat 12 and the leaf spring 13, respectively, and the opening 10 is opened and removed.

FIG. 3 shows a second embodiment of the present invention. In this embodiment, a spring seat 22 fixed to a predetermined outer periphery of the hollow body 5 via a leaf spring 23 and a connecting member 21 is attached to the tip of the spring seat 22. The opening 1 is provided so that its direction is parallel to the opening 10.
0 can be opened and closed in the front and rear directions.

As is clear from the above, according to the present invention, there is no need to attach or detach the horizontal bar as in the past when installing and removing the Hiji Line, and it becomes possible to install and remove the Hiji Line in a very short time with simple operations. Therefore, its practical effect is remarkable.
