Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a spring seat, that is, a spring seat, interposed between a leaf spring and an axle case in a vehicle by a U-bolt, and more particularly to a plurality of members. Welding of the spring seat consisting of a single body to the axle case facilitates installation work, and by making the welded parts of the spring seat orthogonal to the axle case, the spring seat is made rigid and the number of parts is reduced. The present invention relates to a method for reducing manufacturing cost by manufacturing with a small number of plate materials.

[Conventional technology]

In the conventional U-bolt connecting device for a leaf spring and an axle case, conventionally, a mounting plate and a spacer plate are arranged on the upper and lower parts of the axle case, respectively, and the leaf springs are collectively attached by the U bolt. Brackets are welded to both sides of the axle case, and spring holding seats that straddle each bracket on both sides are placed on the axle case. It is known that a leaf spring is tightened with a bolt (for example, JP-A-49-126018).
Japanese Patent Laid-Open Publication No. 54-10020).

[Problems to be solved by the device]

In the conventional U-bolt connecting device for the leaf spring and the axle case, since the number of specially shaped parts is large, not only the cost of manufacturing the parts is high, but also a plurality of independent parts can be connected to each other. Since the bolts are fastened collectively, there is a problem that the work of connecting the leaf spring and the axle case is troublesome and the fastening rigidity thereof is reduced. Further, in the case where the brackets are welded to both sides of the axle case, since the brackets are welded individually, there is a problem that it is difficult to position the welding position and the welding work is troublesome. .

The present invention solves the above-mentioned problems of the prior art. A spring seat in which a top plate having a notch for fitting an axle case and side plates having welding edges for the axle case are integrated by welding is fitted to the axle case. Since it can be welded in the mounted state, the mounting work can be facilitated, and the cutout portion of the top plate, which is the welded portion of the spring seat to the axle case, and the adhesive edge of each side plate are made orthogonal to each other. By doing so, it is possible to increase the rigidity of the spring seat,
Moreover, it is an object of the present invention to provide a spring seat that can be manufactured by a three-point component made of a plate material of a top plate and each side plate, so that the manufacturing cost can be reduced.

[Means for Solving the Problems]

In order to achieve the above object, in the spring seat of the present invention, the top is formed in an inverted U-shape in cross section, and is provided with a downward cutout portion for fitting the axle case facing the central portions of both sides. A side plate having a plate is welded to opposite lower end portions of both sides of the top plate, each side plate having an axle case bonding edge orthogonal to the cutout portion and a bolt hole close to each side portion.

[Action]

The spring seat configured as described above has an inverted U-shaped cross section.
Downward cutouts for fitting the axle case are made on both sides of the letter-shaped top plate, and axle case adhesive edges orthogonal to the cutouts are provided at opposite lower end portions on both sides of the top plate. Since each side plate having the above is welded, when attaching the spring seat to the axle case, by attaching the top plate to the upper surface of the axle case by the notch, the spring seat is welded. Since each notch, which is an edge, can abut on the upper surface and both sides of the axle case, and each adhesive edge of each side plate can abut on both sides of the axle case, the welding position can also be positioned. The attachment work by welding can be easily performed only in the axial direction of the case.

In addition, the welded part of the spring seat to the axle case has parallel notches in the top plate at right angles to the axis of the axle case, while in each side plate, the parallel adhesive edges have the axle case. Since the spring seat is in the same direction as the axis of and has a cross beam shape, the rigidity of the spring seat can be increased by being welded to the axle case.

Furthermore, since the top plate and each side plate that constitute the spring seat are both plate materials, and the plate material consisting of these three-point components is manufactured by bending and welding, the spring seat can be easily manufactured. be able to.

〔Example〕

An embodiment will be described with reference to the drawings. Reference numeral 1 denotes an axle case formed in a rectangular tube shape. The axle case 1 has a spring seat 2 extending from its upper surface portion to both side surface portions.
And a pair of U bolts suspended on the upper surface of the leaf spring 3 on both sides of the spring seat 2.
While the 4 and 4 threaded parts penetrate, the nut 5 ...
By tightening the spring seat 2 and the leaf spring 3 with each other, the axle case 1 is connected to the leaf spring 3 via the spring seat 2.

Then, the spring seat 2 is composed of a three-point component made of a plate material of the top plate 6 and the pair of side plates 9 and 9 ', and the top plate 6 is formed by bending to have an inverted U-shaped cross section. At the same time, the notches 8 and 8'downward facing the central portions of the side portions 7 and 7'for fitting the axle case 1 are formed. Further, both side portions 7,7 ′ located on both sides of each notch portion 8,8 ′ of the top plate 6
A pair of side plates 9 and 9'having adhesive edges 10 and 10 'to the axle case 1 orthogonal to the cutouts 8 and 8', respectively, are formed at the respective opposite lower ends of the top plate 6 so as to be orthogonal to the axis of the top plate 6. Each of the side plates 9 and 9'has an extension formed on both sides of the top plate 6 on both sides 7, 7 '. Bolt holes 11 ... through which a pair of U bolts 4, 4 pass through are formed near 7 and 7 ', and other than the adhesive edge 10, 10' of the axle case 1 of each extension described above. Reinforcing pieces 12, 13, 14, 1 bent upward at each of the two edges
5 and 12 ', 13', 14 ', 15' are connected,
Between the reinforcing pieces 12,13; 14,15; 12 ', 13'; 14 ', 15' and between the reinforcing pieces 13,13 ';15,15' and both sides 7,7 'of the top plate 6.
The gaps between the bolt holes 11 are welded together.
... can be reinforced and effective bolt tightening can be achieved.

When mounting the spring seat 2 thus configured to the axle case 1, the notches 8 and 8 of the top plate 6 are fitted and mounted on the axle case 1 at predetermined positions on the upper surface of the axle case 1. Each notch 8,8 'of the top plate 6 which is the contact portion of the spring seat 2 and each adhesive edge 10,1 of each side plate 9,9'
At 0 ', both are welded and the spring seat 2 and the leaf spring 3 integrated with the axle case 1 are tightened with a pair of U bolts 4, 4 and nuts 5 ... Can be connected.

[Effect of device]

The present invention is configured as described above, and the top plate having notches for fitting the axle case on both sides and the pair of side plates having the axle case adhesive edges are integrated by welding. Since the spring seat is configured by the above, when mounting the spring seat on the axle case, the spring seat is fitted and mounted on the axle case by the notches, and Since the notches of the top plate and the adhesive edges of the side plates can be welded to the axle case by positioning only in the axial direction, the mounting work can be facilitated and the notches of the top plate 6 can be achieved. And is the welded part formed by each adhesive edge of each side plate exhibiting a double girder shape? The spring seat can be made rigid by being welded to the axle case, and the spring seat is manufactured by bending and welding a plate material consisting of three-point parts of the top plate and each side plate. Therefore, it is possible to facilitate the production and reduce the production cost.
