Abstract

PURPOSE:To ensure the supply of a lubricant and reduce the number of times of its replenishment, by storing the lubricant in an opening under a spherical male member secured on the lower end of a cylinder and by supporting the male member in a female member so that the male member can swing. CONSTITUTION:A male member 5, which is secured on the lower end of a cylinder 4, is shaped spherically at a radius R, nearly as a whole. The bottom of the male member 5 is cut off and shaped spherically at a radius L larger than the former radius R, so that an opening 6 is defined. A female member 7 is secured with a plurality of beams 8 on a vehicle body 2. The inside surface of the female member 7 is shaped spherically at the radius R. The female member 7 is split into an upper and a lower portions 9, 10 along the plane containing the center for the radius R. The male member 5 is supported in the female member 7 so that the male member can swing. Lubricating oil 11 is stored in the opening 6 between the male and the female members 5, 7.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a system for smoothly supplying lubricant.
This is A related to the 1st support equipment.

The conventional supporting device for the shilling is the shilling (O
l) A spherical male member (02) is provided at the lower end, and the male member (02) is held by a female member (o3) fixed to a suitable stand by swinging. Further 6τ female member (o3)
A notch (04) tf for lubricant storage is provided on the inner wall so that the lubricant is supplied by the swinging of the male part 4 (02).
It has become i7.

But 1. In the case of the above structure, if the lubricant in the notch becomes somewhat low, the lubricant will collect at the bottom of the notch and come into contact with the male member. There was a drawback that it didn't work.

The present invention has solved the drawbacks as mentioned above, and now the harmful flow side will be explained with drawings. is the car body (2
A cargo box (3) is tiltably mounted on top of the cargo box (3), and a telescopic cylinder (4) for tilting the cargo box (31) is provided between the cargo south part (3) and the vehicle body (2). (4) The lower end is
It is supported so that it can swing like a vine following the tilting, twisting, etc. of the cargo box (3).

Next, the present invention will be explained with reference to FIG. 2. (5) is a member fixed to the lower end of the sill (4), and the male member (5) is formed substantially entirely into a spherical shape with a radius R. Only the lower end of the male member (5) is cut out to form a spherical surface 2 with a radius R6 greater than 6 to form a notch (6).

On the other hand, a female member (7) for supporting the male member (5) in the front 4e

Fig. 3 and Fig. 4 are other embodiments of the main part of the beam, in Fig. 3 a horizontal groove notch 113 is formed at the lower end of the male member Q2, and in Fig. 4 the lower end of the male member stopper is formed. 7, a spherical notch (19) with a radius r smaller than the radius R of the male member (2) is formed, and these notches v (131f151 VC
It is designed to store lubricant.

Note that the structure of the notch is not limited to that of the embodiment described above, but any structure that is formed on the male member side and stores h1 lubricant is satisfactory.

As described above, the present invention forms a notch at the lower end of the spherical male member fixed to the F end of the sling [7], while the male member is swingably held by the female member [7, two front notches] In order to be sure, the lubricant is stored in the inner surface of the female member, so that the lubricant can be reliably supplied by the swinging of the sill, and even if the lubricant is low, the lubricant will always be on the inner surface of the female member due to its own weight. Since the lubricant is in contact with L, there is no need to frequently replenish lubricant as in the past.
