Description
Technical field
The utility model belongs to technical field of automobile components, especially a kind of spheroidal graphite cast-iron heavy truck wheel hub.
Background technology
As the most important safety component of automobile, wheel hub subjects the pressure of automobile and loading mass action, is subject to vehicle
The effect of dynamic torque when starting, braking, turns, the punching of concave-convex road surface, road obstacle in the process of moving also subject to automobile
The irregular alternation stress generated from different directions dynamic load such as hit.The product quality and reliability of wheel hub are not only related to
Vehicle and passengers inside the car, the security of goods and materials also affect the performances such as stationarity, maneuverability, the comfort of vehicle under steam,
Meanwhile the important component of wheel hub or automobile appearance.
Heavy truck has higher requirement since load is larger, to the load-carrying properties of wheel hub.Heavy truck wheel hub at present
It is not corrosion-resistant mostly using cast steel material, and wheel hub load-bearing capacity is poor, easy fracture, and service life is short, and in addition cast steel has to pass through
Heat treatment, expends a large amount of energy consumptions, and presentation quality is poor.
Therefore, the applicant develops a kind of spheroidal graphite cast-iron heavy truck wheel hub, and improvement, nothing are made in terms of structure and material
It needs to be heat-treated, to reach reduction energy consumption and put forward high performance purpose.
Utility model content
The purpose of the utility model is to overcome above-mentioned technical deficiencies, provide a kind of spheroidal graphite cast-iron heavy truck wheel hub,
Improvement is made in terms of structure and material, there is stronger ductility and impact resistance, without heat treatment, reduces energy consumption, presentation quality
It is good.
To reach above-mentioned technical purpose, scheme provided by the utility model is：
A kind of spheroidal graphite cast-iron heavy truck wheel hub, including ductile cast iron wheel hub body, the ductile cast iron wheel hub body bag
Axle bearing mount portion is included, the center of the axle bearing mount portion is equipped with axis hole, and one end of the axle bearing mount portion is outer shaft socket end, another
It holds as inner shaft socket end, the inner shaft socket end of the axle bearing mount portion is equipped with the first radial flange, close to outer on the axle bearing mount portion
Bearing end is connected with the connection support plate of truncated cone-shaped, and the connection support plate connects the second radial flange, the connection support plate
It is coaxially disposed with the axis hole, circumferentially arranged with bolt hole in the connection support plate.
As an improvement the taper of the connection support plate is 2:1.
As a further improvement, the ductile cast iron wheel hub body is QT500-7 ductile cast iron wheel hub bodies.
As a further improvement, it is equipped with reinforcing rib between second radial flange and the connection support plate.
Due to the adoption of the above technical scheme, the beneficial effects of the utility model are：
Spheroidal graphite cast-iron heavy truck wheel hub provided by the utility model has the mechanical performance close to normal steel casting, is not required to
Energy consumption is reduced through Overheating Treatment, and presentation quality is good, and the inner shaft socket end of axle bearing mount portion is equipped with the first radial flange, increases
Strong structure support strength, axle bearing mount portion connect the second radial flange by the connection support plate of truncated cone-shaped, greatly enhance structure
Intensity improves the load-carrying ability of wheel hub, extends the service life of wheel hub.
