Problems solved by technology
Due to their own characteristics, some existing materials can meet the rigidity and strength requirements of the rim under the premise of reducing the thickness of the rim. However, due to the existence of welding, it is easy to become soft and difficult to control, resulting in unreliable welds and low strength, which cannot meet the high requirements of the rim. strength requirements
Due to the limited existing technology, it is difficult to make the wheel hub meet the requirements under the premise of reducing the thickness of the rim, and the lightweight wheel hub still needs a lot of progress to meet the current high demand.

Embodiment Construction
[0025] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.
[0026] A method of welding a rim provided in the present embodiment example, pulse flash butt welding, comprising the following stages:
[0027] S0: preheat phase, to pre-heat pulse is set to preheat the dual phase steels the volume flattened circle, wherein, the preheating amount is 5.5mm.
[0028] S1: flash stage, dual phase steel strip after the roll flattened circle is heated to a plastic deformation temperature reaches duplex steels, dual phase steel edge forming a layer of liquid dual phase steel layer, wherein the burn-off pressure of 9.5 MPa, the clamping pressure is 11Mpa, the amount of burnt 3mm, current 950A, voltage is 5V.
[0029] S2: stage upset, forging pressure is applied, the gap between the end faces dual phase steel is closed, while the end faces of the extruded dual-phase steel and liquid oxide inclusions, so that a clean plastic ...

Abstract
The invention discloses a butt welding method of a wheel rim, a wheel hub and a wheel rim, belonging to the field of lightweight tubeless hubs. A butt welding method of a wheel rim includes the following stages: S1: flash stage, S2: upsetting stage. A wheel hub, comprising: a wheel rim, using the above-mentioned wheel rim, a wheel spoke, one end of which is located inside the wheel rim and is welded on the inner wall of the wheel rim, the wheel spoke is provided with an air hole, the wheel spoke is made of ultra-fine steel, and a valve is provided at one end. On the rim, the other end is set towards the air hole. The butt welding method of the wheel rim, the wheel hub and the wheel rim of the present invention adopts the dual-phase steel as the material of the wheel rim, and adopts the pulse flash butt welding method to carry out the butt welding.
Description
Technical field [0001] The present invention is in the field of lightweight tubeless wheels, in particular to a wheel rim, a hub and a rim welding methods. Background technique [0002] The hub is subjected is interposed between the tire and the axle load and the rotating assembly usually consists of two major components composed of the rim and the spokes. The rim is mounted on the hub member and the support of the tire, spokes member is interposed between the support axle and the rim on the hub. [0003] With the rapid development of the automotive industry, new energy, energy saving, environmental protection and other direction is the development trend of the car, for car companies increasingly attach importance to research lightweight vehicles. Lightweight wheels which is the focus of the object of study. [0004] Present automobile enterprise hub made lightweight process, primarily in the selection of materials, by reducing the thickness of the rim, but again it is possible t...
