Abstract

PURPOSE:To make a wheel for a motorcycle or the like lightweight and to simplify the manufacturing thereof, by superposing right and left rims on an outer flange which constitutes a wheel disc together with right and left flanges, and-by caulking the side flanges inward to fasten the rims while the rims are welded to the outer flange. CONSTITUTION:Right and left rims 4 are superposed on the outer flange 2 of a wheel disc 1, and the side flanges 3 of the wheel disc are caulked inward along the inner end to fasten the rims 4 while the rims 4 are welded to the outer flange 2. With this arrangement, it is possible to facilitate the manufacturing of the wheel, to enhance the strength thereof and to make the wheel lightweight.

で、製造コストが高くつく。2. Description of the Related Art In vehicles such as motorcycles, parts are becoming 111 m long as a means of improving vehicle performance, and wheels are also required to be lighter. One way to reduce the weight of wheels is to use die-casting from light alloy, but in the case of U construction, a certain wall thickness is required, and the manufacturing cost is high due to the use of casting molds. be. There is also a wheel disc in which a roll-formed rim is connected, but in order to maintain the strength of the rim, the required strength is adjusted to the heaviest load area, so the plate thickness is adjusted to the required strength area. For this reason, it is known that the rim part is cast and connected to the hub using plate spokes, as shown in Japanese Patent Publication No. 55-35214, but the assembly work and parts manufacturing work are complicated. , manufacturing costs are high.

An outer flange 2 and left and right side controls 3 are provided and molded in a character shape. rim 4
This is a half-cut type, which is press- or roll-formed using a light alloy plate or steel plate. The left and right rims 4 overlap their inner peripheries on both sides of the outer flange 2 of the wheel disc 1. Then, the left and right side controls 3 are caulked to the inner periphery outer side of the full-circumference rim 4 by rolling or the like, and the rim 4 is crimped to the outer flange 2. Furthermore, the left and right rims 4 and the outer flange 2 are welded at the outer peripheral portion of the outer flange 2. The wheel disc 1 is connected to the tips of spokes 6 of a hub 5 with bolts, and a tire is fitted onto the rim 4.

られる。(Operation of the invention) The left and right rims 4 have their inner circumferential portions overlapped with the outer flange 2 of the wheel disc 1, and the side controls 3 are crimped inward along the inner edge to fix them, and the outer rim 2 and the left and right rims are 4 is fixed by welding, it is securely fixed at two places, and the strength and rigidity can be increased. Since the rim 4 is a plate (A), it can be made light as a rest.In this way, it is advantageous in terms of section modulus and high strength can be obtained.

The rim is crimped inward and the rim is crimped, and the left and right rims are welded to the outer rim at the outer periphery of the outer rim, fixing the left and right rims to the wheel disc. The rim is fixed at two points, the caulked part and the welded part, and has a high section modulus and high strength.The rim is made of thin plate material, making it lightweight and easy to manufacture.
Can be manufactured cheaply.
