TH71715B - Casting wheels for saddle-mounted vehicles - Google Patents

Abstract

To provide forged wheels for saddle-driven vehicles which will include; Wheel hub where axle Will be inserted in; The rim that surrounds the hub coherently; And a certain number of spokes that are connected Wheel hub and rim Where the hub, rims and spokes are individually machined by casting where it is possible to increase rim strength while achieving This reduction in weight and resulting in improved appearance quality by avoiding increasing the size of the hub, each of the 15a spokes will be united with the 15a main spokes and the spokes. The 15b solid-branched and formed Y-shape, the main spoke 15a extends towards rim 14 from the hub 13, and is tapered towards rim 14. The 15b branched spokes are branched into two from the main spoke section 15a and are in continuous line with rim 14 part of the main spoke section 15a from the hub 13 to the branching 20 of the spoke section. The 15b branched wheels are molded into a hollow closed section shape to provide a The hollow part on the spoke side 22, located inside the opening 23, connected to the hollow on the spoke side 22, is provided in at least the 20 branching section of the spoke 15.

Claims (4)

Disclaimer (all) which will not appear on the advertisement page: Amendment 9 Tuk 61 Claims 1. Casting wheels for saddle-mounted vehicles. That includes the hub (13), where axle (12) is inserted into it, the rim (14) that surrounds the hub (13) co-axially, and a certain number of spokes (15) that connect the hub. The wheels (13) and rims (14), in which the hub (13), rim (14) and spokes (15) are united by casting. Where each spoke piece (15) is united, with the main spoke section (15a) and the solidly branched spoke (15b) and formed into a Y shape. The main spokes (15a) protrude while being tilted to one side in the peripheral direction relative to the radial direction toward the rim (14) from the hub (13), and is also being molded. Also tapered towards the rim (14), where the branched spokes (15b) are branched into two from the main spokes (15a) at the location separated from the hub (13). Towards rim (14), is continuous with rim (14) and overhang while receiving a significant tilt in comparison to the main spokes (15a) on the same side as Main spokes (15a) A portion of the main spoke section (15a) from the hub (13) to the branching (20) of the branched spokes (15b) are formed to have The closed section shape is hollow in order to have a hollow section. On the spoke side (22) in it, and the opening (23) connected to the hollow part on the spoke side (22) is provided at least. The most branching (20) of the spokes (15) +++++++++++++++++++++++++++++ 1.Cast wheels for saddle-driven vehicles That includes: wheel hub (13) where axle (12) will be inserted; The rim (14) that surrounds the hub (15) that connects the hub (13) and rim (14), with the hub (13), rim (14) and spokes (15) being formed. Integrally formed by casting, where: Each spoke piece (15) is united as one piece with the main spoke (15a) and spoke sections. It has a solid branching (15b) and is formed into a Y-shape, the main spokes (15a) that extend towards the rim (14) from the hub (13) and are formed. Tapered towards the rim (14), the branched spoke (15b) that is branched into two from the main spokes (15a) at the location where it separates from the hub (13) to the rim. (14) and is characterized by continuous rims (14); Part of the main spoke section (15a) from the hub (13) to the branching (20) of the branched spoke section (15b) is formed into a hollow closed-section shape. To make The hollow part on the spoke side (22) is inside; And the opening (23) connected to the hollow part on the spoke side (22) is provided in At least the branching (20) of the spoke (15) 2. Casting wheels for saddle-mounted vehicles according to claim 1, where the hub (13) will be formed in order to include: the inner cylinder (13a) to be formed. Insertion hole (16) where shaft (12) will be inserted; And the outer cylindrical portion (13b) that surrounds the inner cylinder (13a) in such a way that the hub end (13) of the spoke (15) is continuously provided and the The hollow on the ring hub side (17) is formed between the inner cylinder (13a) and the outer cylinder (13b) the hollow on the hub side (17) that is connected to Externally at both ends along the axis of the insertion hole (16), and also connected to the hollow on the spoke side (22). 3. Forged wheels for saddle-seated vehicles in accordance with claim 1 or 2, where the protruding hollow section (22a) extending towards the rim (14) from the branching section (20) is Formed in the main spoke section (15a) to connect with the hollow section on the spoke side (22), the opening (23) is formed into the spokes (15) from the branching (20). ) To the leading end Of the hollow section, the protrusion (22a) and the reinforcing ridge (24) approaching the hollow section, the protrusion (22a) from the branching (20) is arranged in such a way that the protrusion on the edge of the opening of Openings (23) 4. Forged wheels for saddle-mounted vehicles, one to three rights claims, where the width (W1) of the branched wheel portion (15b), when viewed in the axial direction of the hole. The insertion (16) is set the same from the branching (20) to the rims (14).
