Description

All-terrain vehicle rocker arm assembly

Technical Field

The application relates to the field of vehicle accessories, in particular to an all-terrain vehicle rocker arm assembly.

Background

The rocker arm assembly of the all-terrain vehicle is a structure used for controlling the steering of wheels on the all-terrain vehicle, generally speaking, each wheel of the all-terrain vehicle is connected with one set of rocker arm assembly, and each rocker arm assembly is in transmission with a steering wheel of the all-terrain vehicle, so that when the steering wheel is rotated, the rocker arm assembly can drive the wheels to turn.

The structure of the product can refer to a front suspension device for an all-terrain vehicle disclosed in Chinese patent document CN212860981U, and in addition, structures such as a front upper rocker arm, a front lower rocker arm, a wheel axle support and the like are also disclosed in the all-terrain vehicle disclosed in Chinese patent document CN 216102609U. In the prior art, a rocker arm of a rocker arm assembly is generally in an A shape, and a rod piece forming a lower rocker arm is a straight rod, so that the strength of the rocker arm is ensured. However, in practical use, the lower rocker arm is close to the ground, so that the lower rocker arm is easy to scratch when the all-terrain vehicle runs over rugged and uneven places, and the normal traffic of the all-terrain vehicle is influenced.

At present, no all-terrain vehicle rocker arm assembly capable of ensuring the trafficability performance of all-terrain vehicles exists.

Referring to fig. 1-2, an all terrain vehicle rocker arm assembly, comprising: the wheel axle support 1, the lower rocker arm and the upper rocker arm 3. Wherein, the bottom of lower rocking arm 2 and upper rocking arm 3 all rotates and is connected to wheel axle support 1, and wheel axle support 1 is used for connecting the tire wheel hub, and then makes wheel axle support 1 and upper and lower rocking arm be connected to the tire of all-terrain vehicle, and the relation of connection between the two is prior art, and this application does not improve this, and therefore no longer give unnecessary details here. The upper rocker arm 3 is located above the lower rocker arm. The top ends of the upper rocker arm 3 and the lower rocker arm are respectively connected with a steering wheel through a conventional scheme, so that when the steering wheel rotates, the lower rocker arm can correspondingly act and drive the wheel axle hub connected with the corresponding wheel axle support 1 to rotate. Specifically, the lower rocker arm comprises two long rods 2 with one ends arranged in a superposition mode and a cross rod 5 connected between the two long rods; the coincident ends of the two long rods 2 are rotatably connected to the wheel axle support 1, namely the long rods and the cross rods are combined together to form an A-shaped lower rocker arm.

In order to solve the problem of poor trafficability of all-terrain vehicles, in the present embodiment, long rod 2 includes connecting section 21 and movable section 22. The connecting section 21 is located below the movable section 22, and one end thereof is rotatably connected to the wheel axle support 1, and the other end thereof is fixedly connected/integrally formed with the movable section 22. The connecting section 21 is arranged obliquely with respect to the horizontal, and the end of the connecting section 21 close to the movable section 22 is higher than the end close to the wheel axle support 1. Likewise, the movable section 22 is disposed obliquely to the horizontal direction. Meanwhile, one end of the movable section 22 close to the connecting section 21 is lower than the other end thereof, so that the whole long rod 2 tends to be obliquely and upwardly arranged from the connecting section 21 to the movable section 22. And the inclination angle of the connecting section 21 relative to the horizontal direction is larger than that of the movable section 22 relative to the horizontal direction, so that the size of a space between one end, close to the ground, of the lower rocker arm and the ground is increased, the integral height of the lower rocker arm is increased, the space at the bottom of the all-terrain vehicle is increased, and the possibility that the lower rocker arm contacts a bottom surface obstacle is reduced.

In the embodiment, although the passing performance of the all-terrain vehicle is improved, the long rod 2 is not a straight rod as in the prior art, but an included angle is formed between the connecting section 21 and the movable section 22. In fact, such an arrangement affects the load capacity of the long rod, which may deform or even break the long rod 2 when the lower rocker arm is overloaded. In order to ensure the loading capacity of the lower rocker arm, the inclination angle of the connecting section 21 relative to the horizontal direction is not too large, and in the embodiment, the included angle between the connecting section 21 and the horizontal direction is limited to 35-60 degrees. Meanwhile, the included angle between the connecting section 21 and the movable section 22 is not too small, and in this embodiment, the included angle between the connecting section 21 and the movable section 22 is limited to be 110 ° to 160 °. Most preferably, the angle between the connecting section 21 and the horizontal is 50 degrees, and the angle between the connecting section 21 and the movable section 22 is 120 degrees, so that the load capacity of the lower rocker arm is ensured while the traffic performance of the all-terrain vehicle is improved.

In a further preferred embodiment, the connecting section 21 is integrally formed with the movable section 22 to simplify the structure of the long pole 2 while further ensuring the strength of the long pole 2.

In a further aspect, the length of the connecting section 21 is less than the length of the movable section 22. Horizontal pole 5 is located between two linkage segments 21 of two stock 2, horizontal pole and linkage segment 21 integrated into one piece, and horizontal pole 5 is located the latter half of rocking arm down promptly, when utilizing horizontal pole 5 to strengthen stock 2's intensity, has filled the space between two linkage segments 21 through the horizontal pole, and then can reduce debris and pile up the possibility between two linkage segments 21 to further improve all terrain vehicle's trafficability characteristic.

In addition, universal joints 4 are respectively installed between the lower rocker arm 2 and the wheel axle support 1 and between the upper rocker arm 3 and the wheel axle support 1, and the universal joints 4 are commercially available and used for rotatably connecting the upper rocker arm 3 or the lower rocker arm 2 to the wheel axle support 1 so as to realize power transmission from the two rocker arms to the wheel axle support 1 and further enable tires installed on the wheel axle support 1 to complete turning.

The foregoing description is only exemplary of the preferred embodiments of the disclosure and is illustrative of the principles of the technology employed. It will be appreciated by those skilled in the art that the scope of the invention in the embodiments of the present disclosure is not limited to the specific combination of the above-mentioned features, but also encompasses other embodiments in which any combination of the above-mentioned features or their equivalents is made without departing from the inventive concept as defined above. For example, the above features and (but not limited to) technical features with similar functions disclosed in the embodiments of the present disclosure are mutually replaced to form the technical solution.
