Description
Technical Field
The utility model relates to an automobile wheel hub production technical field, concretely relates to high pressure die forging wheel.
Background
The existing wheel hub is generally manufactured by adopting a die-casting mode, namely molten aluminum liquid is poured into a die-casting machine and is die-cast and molded by utilizing a die in the die-casting machine, but the process molding can be limited to a traditional simple structure, and compared with the situation that forging cannot be carried out if some structural details are complex or structural function requirements are high, in the existing market demands, a high-pressure die forging process gradually replaces a common die forging process, the wheel hub manufactured by the high-pressure die forging process can change an original non-die-casting structure in a local or small range to improve the performance of the wheel hub or change the original function, particularly the original matching connection between the wheel hub and the tire, if the matching degree between the tire and the wheel hub is poor, the air leakage between the connecting gap between the tire and the wheel hub is caused, the inner side surface of the tire is tightly attached to the outer side surface of the wheel hub, and if the air in the tire, the adhesion between the tire and the hub is not enough, the tire is easy to be disengaged or the tire is directly blown out during high-speed running, although the possibility is not high, the process has a certain probability, and the subsequent finish machining including sanding, polishing and other processes is needed, so that the conventional spoke has a smooth surface, and is easy to break or crack under strong external force impact, thereby causing certain potential safety hazards.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a simple structure, reduce tire dropout and blow out emergence under the insufficient condition of child gas, and effectively strengthen spoke intensity, reduce wheel hub and cause the high pressure die forging wheel of probability of bursting because of external shock.
In order to solve the above problem, the utility model adopts the following technical scheme:
the utility model provides a high pressure die forging wheel, includes retaining ring, rim, spoke and central connection pad, spoke one side is connected at retaining ring inner circumference side, opposite side and is connected on the central connection pad, the retaining ring distributes on the left and right sides of rim, the rim includes the outer circle body, middle circle body and the inner circle body that turn right from a left side and connect gradually between the retaining ring of both sides, the outer circumference side of outer circle body and inner circle body and both sides retaining ring junction is equipped with the annular groove, the outer circumference side evenly distributed of annular groove has the rib, middle circle body and the outer circumference side of outer circle body and inner circle body junction are the radius angle.
The further technical scheme is that the depth of the annular groove is 2mm, the thickness of the ribs is 1-1.5mm, and the distance reasonably calculated does not influence the normal use performance of the hub.
The technical scheme is that the ribs are of a rectangular structure, gaps are formed between the ribs and the ribs, the bottom ends of the ribs are tightly attached to the outer side surface of the annular groove and are of an integrated structure, and the width of the left side and the width of the right side of each rib are consistent with that of the annular groove.
The further technical scheme is that bulges are arranged outwards at the positions, close to the retainer rings at the two sides, of the outer ring body and the inner ring body and are mainly used for limiting the left and right movement of the tire.
The utility model has the advantages that: the utility model relates to a high pressure die forging wheel, compared with the structure in the past, this structure utilizes the rim to make the tire can not remove in the left and right sides direction of rim lateral surface, and make the tire equally can not rotate to increase its frictional force and prevent the tire dropout for the rim on the rim, especially under the tire pressure is not enough and the high-speed removal condition, and still have retaining ring department when receiving external force impact, reduce the condition that wheel hub breaks or splits and the tire blows out, and simultaneously, in order when external force from the spoke atress of outer circle body department side, the stress between circle body and outer circle body and the inner circle body in the middle of the fillet reduces, make the impact force that receives reduce, reduce the cracked probability of circle body and outer circle body and inner circle body in the middle of the reduction, and have the firm effect of enhancement.

Detailed Description
The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the scope of the present invention can be more clearly and clearly defined.
Referring to fig. 2 to 4, the high-pressure die forging wheel comprises a retainer ring 1, a rim, a spoke 3 and a central connecting disc 2, wherein one side of the spoke 3 is connected to the inner circumference side of the retainer ring 1, the other side of the spoke is connected to the central connecting disc 2, the retainer rings 1 are distributed on the left side and the right side of the rim, the rim comprises an outer ring body 8, a middle ring body 9 and an inner ring body 5 which are sequentially connected from left to right between the retainer rings 1 on the two sides, annular grooves 7 are formed in the outer circumference sides of the joints of the outer ring body 8 and the inner ring body 5 and the retainer rings 1 on the two sides, ribs 4 are uniformly distributed on the outer circumference sides of the annular grooves 7, and fillets 6 are formed in the outer circumference sides of the joints of the.
The depth of the annular groove 7 is 2mm, the thickness of the ribs 4 is 1-1.5mm, and the distance reasonably calculated does not influence the normal use performance of the hub. Ribs 4 are the rectangle structure, have the clearance between rib 4 and the rib 4, and annular groove 7 lateral surface and formula structure as an organic whole are hugged closely to rib 4 bottom, and the width of the 4 left and right sides of rib is unanimous with annular groove 7. The outer ring body 8 and the inner ring body 5 are provided with bulges 10 outwards at the positions close to the retainer rings 1 at the two sides and are mainly used for limiting the left and right movement of the tire.
In the embodiment, the tire is clamped into the annular groove 7 and inflated, the inner circle edge of the tire is tightly attached to the outer side surface of the rib 4, so that the tire cannot move in the left-right direction of the outer side surface of the rim, and the tire cannot rotate on the rim relatively to the rim to increase the friction force of the tire to prevent the tire from being disengaged, especially under the condition of insufficient tire pressure and high-speed movement, and the position of the retainer ring 1 is impacted by external force, the force can be dispersed by the plurality of ribs 4, so that the stress can not be intensively impacted on the rim, the conditions of hub fracture or fracture and tire burst are reduced, meanwhile, the arrangement of the fillet 6 is mainly used for reducing the stress between the middle ring body 9 and the outer ring body 8 as well as between the middle ring body 9 and the inner ring body 5 when the external force is stressed from the spoke 3 at the side end of the outer ring body 8, so that the received impact force is reduced, and the probability of fracture of, and has the effect of strengthening stability.
