Description

Technical Field

[0001] This invention relates to the field of automotive front axle technology, and in particular to an automotive front axle assembly. Background Technology

[0002] Typically, a car front axle assembly includes a pair of wheels, a pair of steering knuckles, a front axle, and a steering tie rod. The pair of steering knuckles are mounted on both ends of the front axle via kingpins, and the two ends of the steering tie rods are respectively connected to the lower arms of the pair of steering knuckles. The pair of wheels are respectively mounted on the ends of the pair of steering knuckles.

[0003] A pair of wheels has a camber angle relative to the vertical line to the ground. The camber angle must be appropriate for the road surface gradient; an improper camber angle will cause uneven tire wear. A suitable camber angle not only allows the wheels to roll closer to a perpendicular angle to the road surface, reducing steering resistance and making steering easier, but also reduces the load on the bearings and their locking nuts, increasing their lifespan and improving safety.

[0004] Generally, the design value for the camber angle of both front wheels is 1°. However, after a series of tire pressure distribution tests, it was found that when the camber angle of both front wheels is 1°, the front axle load ranges from 4.5T to 6.5T. Regardless of whether turning left, going straight, or turning right, the outer tires on both sides experience greater force than the inner tires. This leads to uneven tire shoulder wear. In view of this, in-depth research was conducted to address the above problem, resulting in this case. Summary of the Invention

[0005] The technical solution of the present invention to achieve the above objectives is as follows: a front axle assembly for automobiles, comprising: a front axle shaft and a pair of wheels, wherein the pair of wheels are mounted on the front axle shaft via an angle adjustment structure, and a buffer structure is mounted on the front axle shaft; The angle adjustment structure includes: two pairs of concave vertical limiting blocks, two pairs of auxiliary balls, two pairs of auxiliary rods, one pair of fixed cylindrical limiting blocks, eight pairs of vertical rotating arc convex sliders, eight pairs of vertical arc axes, several vertical arc sleeve springs, one pair of concave horizontal limiting arc blocks, two pairs of horizontal arc rods, four pairs of horizontal sleeve springs, four pairs of tension buffer rods, a rotating assembly, and an auxiliary angle adjustment assembly; A pair of concave horizontal limiting arc blocks are respectively installed on the front axle. Two pairs of horizontal arc rods are respectively inserted into the inner side of a pair of concave horizontal limiting arc blocks. Two pairs of concave vertical limiting blocks are respectively fitted onto two pairs of horizontal arc rods. Four pairs of horizontal mounting springs are respectively fitted onto two pairs of horizontal arc rods. Two pairs of arc convex grooves are respectively opened on the two pairs of concave vertical limiting blocks. Eight pairs of vertical limiting arc convex sliders are respectively movably inserted into the inner side of eight pairs of arc convex grooves. Eight pairs of vertical arc shafts are respectively inserted into the inner side of eight pairs of arc convex grooves, and eight pairs of vertical arc shafts are respectively inserted into eight pairs of... On the vertically rotating arc-shaped convex slider, several vertical arc-shaped spring sets are respectively fitted onto eight pairs of vertical arc shafts. Two pairs of concave vertical limiting blocks are respectively provided with ball grooves. Two pairs of auxiliary balls are movably arranged inside the two pairs of ball grooves. Two pairs of auxiliary rods are respectively installed on the two pairs of auxiliary balls. A pair of fixed cylindrical limiting blocks are respectively installed on the two pairs of auxiliary rods, and the pair of fixed cylindrical limiting blocks are connected to a pair of wheels via a rotating assembly. Four pairs of tension buffer rods are installed on the eight pairs of vertically rotating arc-shaped convex sliders. The auxiliary angle adjustment assembly is installed on the two pairs of concave vertical limiting blocks. It should be noted that, as described above, by fixing a pair of wheels to fixed cylindrical limit blocks, during operation, the wheels drive the fixed cylindrical limit blocks, which in turn drive a pair of auxiliary rods, which in turn drive auxiliary balls. The auxiliary balls rotate vertically within the ball grooves on the inner side of a pair of concave vertical limit blocks, thus achieving multi-angle support in the vertical direction. Simultaneously, several vertical limit arc convex sliders and the inner side of the arc convex grooves provide vertical limitation. The two pairs of concave vertical limit blocks extend and retract horizontally along two pairs of horizontal arc rods, and the horizontal sleeve springs on them limit the angle of the lower vertical limit blocks. This combination allows the wheels to run within a certain range of the ball arc during operation, achieving a buffering effect and reducing the pressure on the axle. The rotating component limits the rotation of the wheels and the inner side of the fixed cylindrical limit blocks, and the flipping rubber pad adjustment component buffers and limits the vertical rotation.

[0006] Preferably, the buffer structure includes: a pair of lifting and lowering limit blocks, a pair of axle fixing blocks, a pair of automotive leaf springs, two pairs of automotive leaf spring limit blocks, and several lifting and lowering limit sliders; Each pair of lifting loop-shaped limiting blocks has a pair of opening-shaped lifting ports; a pair of axle fixing blocks are fitted onto a pair of front axle shafts; each pair of lifting loop-shaped limiting blocks and their two pairs of opening-shaped lifting ports has a lifting slide rail; two pairs of automotive leaf spring limiting blocks are fitted onto a pair of automotive leaf springs; several lifting limiting sliders are respectively installed on the two pairs of automotive leaf spring limiting blocks and the pair of axle fixing blocks; and several lifting limiting sliders are movably inserted into the inner side of several lifting slide rails. It should be noted that, as described above, the front axle shaft drives a pair of axle fixing blocks to rise and fall, so that the pair of axle fixing blocks can rise and fall stably along a pair of lifting and lowering limit blocks. At the same time, the axle fixing blocks squeeze the car leaf spring limit block, so that the car leaf spring is squeezed and can be limited to a certain range of lifting and lowering, thus avoiding the phenomenon of the axle leaf spring being too large during operation.

[0007] Preferably, the auxiliary angle adjustment component includes: a plurality of buffer arc magnets and a plurality of buffer repulsion magnets; Several of the aforementioned buffer arc magnets are respectively mounted on eight pairs of the aforementioned vertically rotating arc convex sliders, and several of the aforementioned buffer repulsion magnets are respectively mounted on eight pairs of the aforementioned arc convex grooves; It should be noted that, in the above, several buffer repulsion magnets on the inner side of eight pairs of circular arc convex grooves repel several buffer circular arc magnets, and the buffer circular arc magnets drive the vertically rotating circular arc convex sliders on them to move and buffer.

A plurality of arc rotating shafts are respectively inserted into the inner side of a plurality of rotating slides, and the plurality of arc rotating shafts are respectively inserted into a plurality of rotating arc sliders. A plurality of arc-shaped sleeve springs are respectively sleeved on a plurality of arc rotating shafts. It should be noted that, in the above description, when the wheel is driven to rotate, the wheel rotates along the inner side of the arc groove through the connected cylindrical connecting column, and rotates around the connecting rotating column on the cylindrical connecting column as the axis. At the same time, the cylindrical connecting column drives the rotating arc slider on it, and the rotating arc slider rotates along the inner side of the rotating slide, thereby achieving the effect of buffering and limiting. At the same time, the horizontal rotation buffering and limiting are achieved through the arc rotating shaft and the arc sleeve spring.

[0009] Preferably, the pair of cylindrical connecting posts are bolted to the pair of wheels.

[0010] Preferably, an angle pad is provided on the inner side of the pair of arc grooves.

[0011] Preferably, each of the four pairs of tension buffer rods is provided with a buffer pad.

The connecting rotating column 19 on the cylindrical connecting column 18 rotates around the axis. At the same time, the cylindrical connecting column 18 drives the rotating arc slider 21 on it.
