Technical field
The utility model is related to technical field of automobile parts, have the motor vehicle of loss of weight nest more particularly to a kind of back of the body chamber
Aluminium alloy wheel hub.
Background technology
The features such as aluminium alloy wheel hub is beautiful and generous with its, safety and comfort has won the favor of more and more private car owners.By
It is light-weight in aluminium alloy wheel hub, the accuracy of manufacture is high, so being deformed in high-speed rotation, small, inertia resistance is also small.Aluminium alloy wheel hub
With the metallic character for absorbing vibration and lifting force, through numerically-controlled machine tool accurate to dimension, out of roundness is high, beat bounce is small,
It balances, keeps running car steadily comfortable.
For automobile aluminium alloy wheel hub when carrying out shape-designing, the design result of front wheel disc may be with weight optimal result
There is certain distance.When front wheel disc covers excessive area, it will make solid wheel that there is excessive wheel disc weight, this is just supported
Disappeared advantage of the aluminium alloy wheel hub in terms of loss of weight.In order to overcome the problems, such as this, loss of weight generally is set at the spoke back side of wheel disc
Nest, to mitigate the overall weight of wheel disc.However, setting loss of weight nest may also lead to the mechanical strength of aluminium alloy wheel hub, especially
Impact strength and fatigue behaviour are affected, and correlation test can not be passed through by even resulting in aluminium alloy wheel hub.
Therefore, this field is wished always by designing suitable loss of weight nest for specific wheel disc frontal design, true
Under the premise of the intensity for protecting aluminium alloy wheel hub, the weight of wheel hub is reduced as far as possible, to be obtained between loss of weight and mechanical strength
Balance.

Spoke side one end is connect with wheel rim, and one end is connect with ring flange.The ring flange outer peripheral portion along wheel radial direction width
For 21.3 ~ 24.3mm, thickness is 21.3 ~ 25.6mm.
The spoke back side of the wheel hub includes spoke loss of weight nest.For the spoke loss of weight nest there are two types of size, shape is equal
It is fillet rectangle.Deep 5.2 ~ the 12.5mm of loss of weight socket, loss of weight nest both ends are respectively apart from 5.3 ~ 17.4mm of spoke border, loss of weight nest
Width be 10.4 ~ 15.3mm, length be 28.2 ~ 37.5mm.
The back side of the ring flange of the wheel hub includes ring flange loss of weight nest, includes 1 flange between each two bolt hole
Disk loss of weight nest, flange loss of weight nest have rhone close to flange end, close to center nose end diameter fluting.Groove width is drained close to flange end
10.3 ~ 16.4mm, deep 5.5 ~ 9.5mm.25.7 ~ 36.4mm of short side, the 33.5 ~ 39.5mm of long side of flange loss of weight nest top surface,
High 20mm, depth 10mm.
Wheel hub by designing specific shape for specific wheel hub front pose carries on the back chamber loss of weight nest, and selects loss of weight nest
Size, realize the reduction of hub weight.And the wheel hub after loss of weight still has outstanding mechanical performance, meets U.S. vehicle
Take turns SAE J175 and SAE J328-2005 standards, i.e. 13 degree of impact strengths, radial fatigue, fatigue property require, while
