Description
Technical Field
[0001] This utility model relates to the field of automotive steering knuckle technology, and in particular to a high-strength automotive steering knuckle with a high-efficiency heating riser. Background Technology
[0002] The steering knuckle, also known as the "steering knuckle," is a crucial component of the automotive steering axle, enabling stable vehicle movement and responsive directional transmission. Its function is to transmit and bear the load from the front of the vehicle, supporting and driving the front wheels to rotate around the kingpin, thus steering the car. During vehicle operation, it withstands varying impact loads, therefore requiring high strength. The steering knuckle acts as the hinge for wheel steering and is generally fork-shaped. The upper and lower forks have two coaxial holes for mounting the kingpin, and the steering knuckle journal is used to mount the wheel.
[0003] In the prior art, automobile steering knuckles need to be formed by casting during the production process. During casting, the riser needs to be aligned with the casting port on the mold to avoid misalignment that could lead to leakage or poor flow of molten metal. Then, the casting equipment is started to carry out the casting work. Molten metal is injected from the casting port of the mold along the preset pouring path, filling the gating system and riser in sequence, and finally smoothly filling the entire cavity of the steering knuckle casting. However, during the casting process, when the liquid metal cools and solidifies in the mold, it will shrink in volume. At this time, the liquid metal needs to be introduced through the riser channel. Because the riser has a channel, its diameter wall is thinner than the steering knuckle body. The grain structure formed after the metal solidifies is also less dense. Naturally, the overall strength is not high and it is difficult to withstand large external forces. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a high-strength automotive steering knuckle with a high-efficiency heating riser.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-strength automotive steering knuckle with a high-efficiency heating riser, comprising a steering knuckle body, a riser body disposed on the top side of the steering knuckle body, the top side of the steering knuckle body being fixedly connected to the bottom end of the riser body, a cone seat disposed on the outer side of the bottom end of the riser body, the outer side of the bottom end of the riser body being fixedly connected to the inner wall of the cone seat, the bottom end of the cone seat being fixedly connected to the top side of the steering knuckle body, a reinforcing ring disposed on the outer side of the riser body, and the outer side of the riser body being fixedly connected to the inner side of the reinforcing ring.

[0011] In a preferred embodiment, a heating layer is provided on the inner surface of the riser body, and the inner surface of the riser body is fixedly connected to the outer side of the heating layer.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example
[0020] like Figure 1-5 As shown, this utility model provides a technical solution: a high-strength automotive steering knuckle with a high-efficiency heating riser, comprising a steering knuckle body 11, a riser body 13 disposed on the top side of the steering knuckle body 11, the top side of the steering knuckle body 11 being fixedly connected to the bottom end of the riser body 13, a cone seat 12 disposed on the outer side of the bottom end of the riser body 13, the outer side of the bottom end of the riser body 13 being fixedly connected to the inner wall of the cone seat 12, the bottom end of the cone seat 12 being fixedly connected to the top side of the steering knuckle body 11, a reinforcing ring 14 disposed on the outer side of the riser body 13, and the outer side of the riser body 13 being... The inner side of the reinforcing ring 14 is fixedly connected to the inner side of the reinforcing ring 14. An inner ring 18 is provided on the outer side of the reinforcing ring 14 and fixedly connected to the inner side of the inner ring 18. A connecting plate 2 111 is provided on the outer circumference of the inner ring 18 and fixedly connected to one end of the connecting plate 2 111. An outer ring 17 is provided on one end of the connecting plate 110 and fixedly connected to the inner side of the outer ring 17. A heating layer 15 is provided on the inner surface of the riser body 13 and fixedly connected to the outer side of the heating layer 15.
[0021] In this embodiment, when the high-strength automotive steering knuckle with a high-efficiency heating riser is used, firstly, before the casting is produced, the process engineer has already completed the design and addition of the riser on the computer. At the same time, the riser must correspond to the gating system, and the flow path of the molten metal must ensure that it can smoothly fill the riser and allow the riser to solidify last. Then, when the riser body 13 is on the steering knuckle body 11, the structure of other parts is relatively thick and naturally has high strength, while the riser body 13 has low strength as a channel. Therefore, a cone seat 12 is installed on the outer side of the bottom end of the riser body 13. The cone seat 12 is sleeved on the bottom end of the riser body 13, providing structural support from the bottom end of the riser body 13. At the same time, a reinforcing ring 14 is installed at the top port of the riser body 13. The reinforcing ring 14 wraps and reinforces the edge of the port of the top of the riser, further improving the structural stability and resistance to external impact of the top of the riser body 13, and preventing the riser from deforming due to the force on the top during subsequent use, thereby affecting the subsequent entry of molten metal. An outer ring 17 and an inner ring 18 are designed on the outside of the reinforcing ring 14. The inner ring 18 is fixed to the port of the reinforcing ring 14 by a sleeve. Multiple connecting plates 111 are designed on the outer circumference of the inner ring 18. Multiple connecting plates 110 are installed on the inner ring 18 of the outer ring 17. An elliptical ring 19 is between the connecting plates 110 and 111. The two ends of the elliptical ring 19 are fixed to the corresponding connecting plates 110 and 111 respectively. The elastic deformation of the elliptical ring 19 can buffer the vibration generated when the steering knuckle is working. With the cooperation of the inner and outer rings 17 and the connecting plates, the reinforcing ring 14 can further enhance the wrapping and reinforcement effect of the riser top, and improve the deformation resistance of the overall structure. The elliptical ring 19 is made of spring steel with a high elastic limit. It can withstand the vibration and impact when the steering knuckle is working for a long time and is not easy to be permanently deformed after repeated deformation. A heating layer 15 is installed on the inner surface of the riser body 13. The heating layer 15 is a heating agent built into the manufacturing material. These heating agents are usually a mixture of aluminum powder, iron oxide and metal oxide. The aluminum powder acts as a reducing agent and the iron oxide acts as an oxidizing agent. After the molten metal is poured, the two can undergo an aluminothermic reaction to release a large amount of heat. The metal oxide can regulate the reaction rate and heating duration, avoid concentrated heat release and local overheating of the riser, and supplement some alloying elements and reduce the oxidation loss of the molten metal in the riser. This prolongs the solidification time of the riser body 13, ensuring that the riser can continuously provide feeding for the steering knuckle casting, effectively reducing defects such as shrinkage cavities caused by shrinkage inside the casting, and improving the overall density and structural strength of the steering knuckle. Finally, after completing a series of work, the riser body 13 is removed from the universal joint body by sawing. Example
[0022] like Figure 1-5As shown, a collar 16 is provided on the outer circumference of the outer ring 17. The outer circumference of the outer ring 17 is fixedly connected to the inner surface of the collar 16, and the bottom end of the collar 16 is fixedly connected to the outer side of the cone seat 12.
[0023] In this embodiment, a collar 16 is installed on the outside of the outer ring 17 and fixed to the outside of the cone seat 12. In this way, the outer ring 17 can be provided with stable radial support and axial limit, so as to prevent the outer ring 17 from shifting due to impact during the operation of the steering knuckle. At the same time, the collar 16 can distribute the external force on the outer ring 17 to the cone seat 12, reduce the local force concentration between the outer ring 17 and the connecting plate 110, and prevent the outer ring 17 from deforming due to long-term stress.
[0024] Working principle: like Figure 1-5 As shown, a cone seat 12 is installed on the outer side of the bottom end of the riser body 13. The cone seat 12 is sleeved on the bottom end of the riser body 13, providing structural support from the bottom end of the riser body 13. At the same time, a reinforcing ring 14 is installed at the top port of the riser body 13. The reinforcing ring 14 wraps and reinforces the edge of the top port of the riser, further improving the structural stability and resistance to external impact at the top of the riser body 13. An outer ring 17 and an inner ring 18 are designed on the outside of the reinforcing ring 14. The inner ring 18 is fixed to the port of the reinforcing ring 14 by a sleeve connection. Multiple connecting plates 111 are designed on the outer circumference of the outer ring 18, while multiple connecting plates 110 are installed on the inner circumference of the outer ring 17. An elliptical ring 19 is between the connecting plates 110 and 111. The two ends of the elliptical ring 19 are fixed to the corresponding connecting plates 110 and 111 respectively. The elastic deformation of the elliptical ring 19 can buffer the vibration generated during the operation of the steering knuckle. With the cooperation of the inner and outer rings 17 and the connecting plates, the reinforcing ring 14 can further enhance the wrapping and reinforcement effect of the riser top, and improve the deformation resistance of the overall structure.

However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
