Description

Technical Field

[0001] The utility model relates to the field related to independent suspension front axles, and in particular to an independent suspension front axle. Background Art

[0002] An independent suspension front axle is a car front axle design that uses an independent suspension system, allowing each wheel to be independently connected to the frame (or body) through the suspension. This design can significantly improve the vehicle's handling and ride comfort because it allows each wheel to jump up and down independently according to road conditions without interfering with each other. Independent suspension front axles are widely used in modern cars, especially in models that pursue high performance and comfort, providing drivers with a more stable and smooth driving experience.

[0003] The current independent suspension front axle has been found to have the following problems during use:

[0004] (1) Existing independent suspension front axles are usually equipped with stabilizer bars to enhance the driving stability of the vehicle. However, the stabilizer bars are prone to deformation or even damage after being subjected to complex road impacts and vibrations for a long time. Since the stabilizer bars and connecting rods are generally connected by bolts, this design is quite inconvenient when the stabilizer bars need to be replaced or repaired, which increases the difficulty and time cost of repairs and brings additional challenges to vehicle owners and maintenance personnel.

[0005] (2) The existing independent front axle lacks the necessary buffer mechanism between the lower cantilever and the upper cantilever, which means that when subjected to external impact or vibration, the connection between the lower cantilever and the upper cantilever will bear all the direct stress, which may not only lead to accelerated structural wear, but also affect the stability and durability of the entire system.

[0006] Therefore, we made improvements to this and proposed an independent suspension front axle. Utility Model Content

[0048] In this embodiment: the connecting plate 911 slides inside the cavity 907, and the two triangular blocks 912 on its surface are engaged with the oblique grooves 913 on the sides of the two clamping blocks 908. When it is necessary to remove the mounting block 905 and the fixing member 904, the triangular block 912 can be driven to slide in the oblique groove 913 by sliding the connecting plate 911, thereby forcing the clamping blocks 908 on both sides to retract inward, releasing the engaged state with the clamping groove 910, and facilitating disassembly.

A second spring 915 is sleeved on the outside of the sliding rod 914, and the second spring 915 is fixedly installed between the connecting plate 911 and the inner wall of the cavity 907.

[0051] In this embodiment: the sliding rod 914 is connected to the connecting plate 911, and also maintains a sliding connection with the fixing member 904 and the mounting block 905, ensuring the stability and guidance of the connecting plate 911 during movement; and the second spring 915 arranged on the outside of the sliding rod 914 is fixedly installed between the connecting plate 911 and the inner wall of the cavity 907, providing a continuous reset force for the connecting plate 911; when the disassembly operation is completed, the second spring 915 will drive the connecting plate 911 to reset through its own tension, so that the triangular block 912 will not engage with the inclined groove 913, preparing for the next installation and disassembly of the mounting block 905.

[0052] As a preferred embodiment, a groove 916 is formed on one side surface of the fixing member 904, and a push block 917 is slidably connected inside the groove 916. The push block 917 is fixedly connected to the sliding rod 914.

[0055] As a preferred embodiment, the buffer mechanism 10 includes a connecting member 1001, and there are two connecting members 1001, and the two connecting members 1001 are respectively fixedly installed on the outer surfaces of the lower cantilever 1 and the upper cantilever 2, and the interiors of the two connecting members 1001 are each provided with a mounting member 1002, and the surfaces of the two mounting members 1002 are respectively fixedly installed with a fixing cylinder 1003 and a fixing rod 1004, and a buffer spring 1005 is fixedly installed between the two mounting members 1002, and the fixing cylinder 1003 is slidably connected to the fixing rod 1004.

[0056] In this embodiment: two connecting members 1001 are respectively installed on the outer surfaces of the lower cantilever 1 and the upper cantilever 2, ensuring close integration with the front axle structure; a mounting member 1002 is provided inside each connecting member 1001, and a fixing cylinder 1003 and a fixing rod 1004 are respectively installed on the surfaces of the two mounting members 1002. The sliding connection between the fixing cylinder 1003 and the fixing rod 1004 not only ensures that the buffer spring 1005 can work smoothly, but also maintains the compactness and reliability of the entire buffer mechanism 10; a buffer spring 1005 is fixedly installed between the two mounting members 1002, which can effectively absorb and disperse energy when the front axle is impacted or vibrated, thereby significantly improving the stability and durability of the front axle.

In the initial state, the elastic force of the third spring 1009 can support the baffle 1007, so that the protrusion 1008 on its surface extends out of the outside of the mounting member 1002; when the mounting member 1002 needs to be fixed to the connecting member 1001, it is only necessary to press the protrusions 1008 on both sides so that the protrusions 1008 overcome the elastic force of the third spring 1009 and slide into the connecting grooves 1006. Then the elastic force of the third spring 1009 will push the baffle 1007 and the protrusion 1008 outward, so that the protrusion 1008 is snapped into the mounting hole 1010 on the connecting member 1001, and the assembly connection is completed; this snap connection method is not only firm and reliable, but also easy to operate, which greatly improves the assembly efficiency and convenience of the buffer mechanism 10.
