JPS59195472A - Car luggage carrier with suspension-type anti-vibration device - Google Patents

Abstract

PURPOSE:To reduce the vibration of a luggage carrier to the minimum by inserting a coil spring between the suspension-type upper and lower brackets. CONSTITUTION:A suspension-type anti-vibration device is constituted with an upper bracket 21 fitted to a chassis frame 2 with fitting bolts and nuts 25, a lower bracket 22 fitted to a vertical joist 13 fixed to a horizontal joist 12 with fitting bolts and nuts 26, and a coil spring fitted between the upper bracket 21 and the lower bracket 22. When luggages are loaded on a truck luggage carrier, the coil spring 23 is pulled downward, and the whole luggage carrier is lowered downward. At this time, the position of the upper bracket 21 fixed to the chaissis frame 2 is stable. When a shock is applied to the chassis frame 2 during the travel, the coil spring 23 located in the middle mitigates most of the shock force.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vehicle loading platform equipped with a vibration prevention device. Conventionally, in a vehicle loading platform, especially a truck loading platform 3, a vertical joist 13 of the loading platform and a chassis frame 2 for supporting the loading platform are used.
A long and narrow buffer a with a rectangular cross section, made of wooden nails (made of Aviton), waste bras (solid waste plastic), or sheet-like belts, is installed between the It was set up.

However, when these cushioning materials (wood, scrap bras, belts) are provided, the vibrations of the vehicle are directly transmitted to the loading platform, causing significant vibrations in the loading platform.

When transporting fragile items such as glass bottles using a truck equipped with such a loading platform, M! Excessive packaging may become necessary to prevent damage. Excessive packaging increases the volume of the cargo and the weight of the truck, which is also disadvantageous in terms of weight.

In order to improve the various drawbacks of the conventional loading platform, the present invention provides an upper bracket 21 and a lower bracket 22 between the vertical joist 13 of the loading platform and the chassis frame 2 for supporting the loading platform, and inserts a coil spring 23 between them. A vehicle loading platform equipped with a vibration prevention device is developed, in which coil springs 23 are attached to a bracket 21 and a lower bracket 22, and an appropriate number of coil springs 23 are installed under the vehicle loading platform over almost the entire length.

An oil damper, which is an elastic body, can also be used instead of the above-mentioned coil spring.

Examples of the present invention will be described below.

FIG. 1 is an overall view of a truck, in which a truck bed 3 is placed on the upper part of a chassis frame 2 via a hanging type anti-vibration device g14 according to the present invention.

Figure 2 shows an enlarged view of the hanging vibration prevention device. It consists of a lower bracket 22 attached to the vertical joist 13 with mounting bolts and nuts 26, and a coil spring 23 attached between the upper bracket 21 and the lower bracket 22 with nuts 24.

When there is no load on the truck bed, it is in a state as shown in Fig. M2, but when there is a load, the coil spring 23 is pulled downward and the entire bed moves downward. At this time as well, the position of the upper bracket 21 fixed to the chassis frame 2 remains unchanged.

Even if an impact is applied to the chassis frame 2 while the truck is running, the impact is only transmitted to the coil spring 23 located in the middle.

The feature of this hanging type is that it is a hanging type, but it is fake.
At any time, the distance between the top and bottom ends of the coil spring (%j) is the minimum distance depending on the load situation at that time. is to come to the position of the amount IJz.
