JPS60113776A - Weight attachement device for tractor wheel - Google Patents

Abstract

PURPOSE:To make it possible to stably attach a weight to a wheel, by engaging a projection formed on a weight in a fitting groove formed in the rim of a wheel. CONSTITUTION:A wheel 1 as a front wheel of a tractor, is formed, in the outer end part of the inner peripheral surface 3 of a rim 2, with a fitting groove 8 directing toward the wheel. Further a cut and raised part 11 is formed inside of a disk 9. Meanwhile a weight 6 is formed with a projection 7 fitted in the above-mentioned groove 8 and a projecting part 10 engaged with the above- mentioned cut and raised part. Upon attachement of the weight 8 to the wheel 1 the projection 7 of this weight 6 is fitted into the groove 8 while the projecting part 10 is engaged with the cut and raised part 11, and thereafter, the weight 8 is attached to the weight to the disk 9 by means of a bolt 12.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a weight attachment device for a tractor wheel, and is an object of the present invention for safely, quickly and easily attaching a weight such as a balance weight to a wheel.

Attachment of wheel weights of riding machines such as tractors requires heavy lifting and manual operation, which is hard labor and involves danger, so there is a strong need to make it easier to install and remove them.

The present invention takes the following technical measures for this purpose.

That is, the inner circumferential surface (3) of the rim (2) of the wheel (1), and the upright portion (5) located at the outer end of the inner circumferential surface (3) and bent toward the wheel (4). Due to this, the convex part of the weight (6) (
7) Fully form the fitting groove (8) for complete fitting, and also this rim (
2) center side wheel (1) disc (9) and the weight (6)
) are formed with a positioning recess θO and a protrusion (11) that fit into each other, and the weight (6) is attached to the entire rim (2).
) and the disk (9) and fixed with a locking tool 0.

This invention has the following technical effects due to such a configuration. That is, wheels (1) of a riding machine such as a tractor.
When installing the AJ weight (6) on the rim (2), install the fitting groove between the inner peripheral surface (3) of the wheel (1) rim (2) and the outer upright part (5). (8) Inside is a weight (6
) convex part (7) for full fitting and four positioning parts (
10 and the protrusion 01), this weight ((i
) It is stably supported by the rim (2) V (without any deviation in the rotational direction by the four parts (In and convex part 01) without coming off in the outward 1 + 111 direction by the kl standing part (5), and the locking tool 0 is easily attached. Since it can be fixed in place, it can be easily attached and detached, making it safe and quick.

In the illustrated example, the wheel (1) is the front wheel of a tractor, and a raised portion (5) is provided at the outer end of the inner circumferential surface (3) of the rim (2) toward the axle (4). ), and a convex portion 01) is provided on the inside of the disc (9) at the same self-registering position, and an insertion hole θ3 for a locking tool θ is provided on both the front and rear sides of the convex portion.
6) is divided into a plurality of circular arcs along the inner circumferential surface (3) of the rim (2), and the outer periphery of the weight (6) is arranged in the fitting groove (
A convex part (7) having a shape to fit with the disc (9) is entirely formed, and a positioning recess Q (Th'i) which fits with the convex part 01) is formed on the side facing the disk (9), and the recess Q (Screw holes θ4) are provided on both the front and rear sides of 1. 0θ is the front wheel suspension system, (1
t9 is a tire.

When attaching the weight (6) to the wheel (1), attach the weight (6) to the wheel (1).
6) Positioning recess 00; protrusion 01 of disk (9)
) When the K fitting convex part (7) is fitted into the fitting groove (8) K fitting ζ,
The weight (6) is supported by the rim (2) V.

Also, since the position is determined by the concave portion 00 and the convex portion 01),
The screw hole θ4) can be aligned with the insertion hole 0■ of the disk (()) and fastened with the locking tool 02 from the outside Ill of the wheel (1).
