Abstract
The utility model provides an inner spoke hub with a felly with the outer diameter of 492 mm. The inner spoke hub with the felly with the outer diameter of 492 mm mainly comprises the felly and a spoke. The felly is of an annular structure. The felly comprises a wheel rim seat and a tyre protecting lug. The wheel rim seat and the tyre protecting lug are integrally formed. One side of the wheel rim seat inclines outwards. The tyre protecting lug is arranged at the end of the inclined side of the wheel rim seat through arc transition. The radius of the tyre protecting lug is 20 mm. The outer diameter of the horizontal portion of the felly is 492 mm. The other side of the wheel rim seat is welded with a support base which is provided with an outward dent. A stopping ring is arranged at the end of the wheel rim seat, close to the dent, and corresponding to the inner side of the dent. A locking ring is arranged inside the dent. The spoke is welded in the middle inside the felly. An air valve hole is formed on the wheel rim seat of the felly. According to the inner spoke hub with the felly with the outer diameter of 492 mm, the wheel rim seat and the tyre protecting lug are integrally formed, the structure is firm, the service life of the hub can be effectively prolonged, and the hub is formed by rolling depression, machining time can be effectively shortened, production efficiency is improved, and accordingly production cost is lowered.
Description
Technical field
The utility model relates to the automotive hub apparatus field, and especially a kind of wheel rim external diameter is the interior wheel spoke barrel of 492mm.
Background technology
Existing wheel hub all adopts the wheel ring support and protects the tire ear and be connected by electric welding, and such structure can make fastness between the two relatively low, affects the service life of wheel rim.And in producing the wheel rim process, artificial electric welding or mechanical electric welding, the required time is all long, makes production efficiency relatively low, thereby has increased productive costs.
The utility model content
The purpose of this utility model is to provide a kind of sound construction for the deficiency that solves above-mentioned technology, takes turns ring support and protects the interior wheel spoke barrel that the integrated wheel rim external diameter of tire ear is 492mm.
In order to achieve the above object, the designed wheel rim external diameter of the utility model is the interior wheel spoke barrel of 492mm, it mainly comprises wheel rim and spoke, wheel rim is loop configuration, wheel rim comprises the wheel ring support and protects the tire ear, take turns ring support and protect the tire ear one-body molded, wheel ring support one side direction outer incline, protect the tire ear and be arranged on the port of taking turns the ring support inclined side by arc transition, the radius that protects the tire ear is 20mm, and the external diameter at wheel rim level place is 492mm, wheel ring support opposite side is welded with supporting bracket, be provided with outside indenture at supporting bracket, be provided with back-up ring at the wheel ring support near indenture end and relative indenture inboard, in indenture, be provided with retainer, described spoke is welded on the midway location of wheel rim inside, is provided with through hole in the middle of the spoke, evenly is provided with several screws in the spoke periphery, be provided with valve port at the wheel ring support of wheel rim.This constructional feature, it is taken turns ring support and protects the tire ear structure that is formed in one, sound construction, but actv. improves the service life of wheel hub.
The resulting wheel rim external diameter of the utility model is the interior wheel spoke barrel of 492mm, it is taken turns ring support and protects the tire ear structure that is formed in one, structure is more firm, the service life that the energy actv. improves wheel hub, and it passes through flow forming, can effectively reduce its overhours, enhance productivity, thereby reduce production costs.
