Abstract
The utility model discloses a double-sheet welding type aluminum alloy hub consisting of a hub main body (1), a mounting ring (2), a middle sheet (3) and a plurality of fastening bolts (5). The double-sheet welding type aluminum alloy hub is characterized in that the hub main body (1) and the mounting ring (2) are respectively formed by casting; a plurality of thread holes (21) are arranged on the mounting ring (2); the mounting ring (2) is fixed on the hub main body (1) in a rotary welding manner, so that a welding strip (4) is formed on the hub main body (1); and the middle sheet (3) is fixed on the mounting ring (2) through the fastening bolts (5). According to the double-sheet welding type aluminum alloy hub provided by the utility model, the hub main body and the mounting ring are respectively cast; when the hub main body is cast, the final shape of the hub main body is not in an inward-concave structure, so that an amount of residual materials can be greatly reduced, the machining difficulty of the residual material can be reduced, the production efficiency is improved, and the yield rate of the finished product is further improved.
Description
Technical field
The utility model relates to a kind of vehicle wheel hub, specifically a kind of aluminium alloy wheel hub.
Background technology
Two-piece type wheel hub on the market is comprised of wheel rim and middle two parts now, when producing this wheel hub, its wheel rim main body and installation ring are by casting shape all-in-one-piece stock, and then this stock is carried out cutting will process clout and remove and obtain the moulding wheel rim, with the mode of screw threads for fastening or welding wheel rim and middle are assembled into together at last.Because the final shape of wheel rim has a sunken inside between installation ring and wheel rim main body (1), for patrix (6) and the smoothly demoulding of counterdie (7), when casting, must leave herein very large one processing clout (8) (seeing accompanying drawing 5), the foundry defect such as local overheating, the inner shrinkage porosite of generation when this blocked up clout can cause the product casting, thereby cause yield rate not high, and so that wheel rim production and processing man-hour is long, waste material is many.
The utility model content
In order to solve the many problems of above-mentioned processing clout, the utility model provides a kind of two-piece type welding aluminum alloy wheel hub, and the technical scheme that the utility model adopts is: be comprised of a wheel rim main body, an installation ring, a middle sheet and several binding bolts; It is characterized in that: described wheel rim main body and installation ring form by casting respectively, and described installation ring has several tapped bore, to install and fix middle; This installation ring is fixed on the wheel rim main body by the mode of rotating welding, thereby forms a welding band in the wheel rim main body, and described middle is fixed on the installation ring by binding bolt.
The utility model adopts the beneficial effect of above technical scheme to be: wheel rim main body and installation ring two parts are cast respectively, the wheel rim main body is when casting, because final shape does not have the sunken inside structure, thereby greatly reduced clout, reduce the difficulty that clout is processed, improved production efficiency, also improved the yields of finished product.
Description of drawings
Fig. 1 is integral structure decomposing schematic representation of the present utility model;
Fig. 2 is integral structure assembling scheme drawing of the present utility model;
Fig. 3 is the scheme drawing of installation ring rotating welding of the present utility model;
Fig. 4 is wheel rim main body casting clout scheme drawing of the present utility model;
Fig. 5 is existing wheel rim casting clout scheme drawing.
Among the figure, sheet, 4 welding bands, 5 binding bolts, 6 patrixes, 7 counterdies, 8 clouts in 1 wheel rim main body, 2 installation rings, 21 tapped bore, 3.
The specific embodiment
As shown in Figure 1, 2, the utility model is comprised of a wheel rim main body 1, installation ring 2, middle sheet 3 and several binding bolts 5; Described wheel rim main body 1 and installation ring 2 form by casting respectively, described installation ring 2 has several tapped bore 21, to install and fix middle 3, this installation ring 2 is fixed on the wheel rim main body 1 by the mode of rotating welding, thereby form a welding band 4(as shown in Figure 3 in wheel rim main body 1), described middle 3 is fixed on the installation ring 2 by binding bolt 5; As shown in Figure 4, described wheel rim main body 1 is when casting, because final shape does not have the sunken inside structure between patrix 6 and counterdie 7, thereby only produce the clout 8 of pouring gate, so just greatly reduced the volume of clout 8, reduce the difficulty that clout is processed, improved production efficiency, also improved the yields of finished product.
The above-mentioned specific embodiment is exemplary, is to be the restriction that this patent is comprised scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as the technology contents essence of making according to the disclosed technical scheme of this patent is identical or any change or the modification that are equal to, all fall into the scope that this patent comprises.
Claims (1)
1. a two-piece type welding aluminum alloy wheel hub is comprised of a wheel rim main body (1), an installation ring (2), a middle sheet (3) and several binding bolts (5); It is characterized in that: described wheel rim main body (1) and installation ring (2) form by casting respectively, described installation ring (2) has several to be used for installing and fixing a tapped bore of (3) (21), this installation ring (2) is fixed on the wheel rim main body (1) by the mode of rotating welding, thereby form a welding band (4) in wheel rim main body (1), described middle (3) are fixed on the installation ring (2) by binding bolt (5).
