The steering limit component 100 is applied to an all-terrain vehicle. All-terrain vehicles refer to vehicles that can travel on any terrain and can walk freely on terrain that is difficult for ordinary vehicles to maneuver.

As shown in FIGS. 1 to 12, the steering limit assembly 100 according to the embodiment of the first aspect of the present application includes a steering limit device 1 and a steering rocker arm 2.

Referring to FIG. 1 in conjunction with FIGS. 2 to 12, the steering limit device 1 has a first limit portion 1111. The steering rocker arm 2 is arranged below the steering limit device 1. The steering rocker arm 2 is rotatable relative to the steering limit device 1. The steering rocker arm 2 has a second limit portion 211, when the steering rocker arm 2 rotates to the limit position The second limiting portion 211 abuts against the first limiting portion 1111, and the second limiting portion 211 is in surface contact with the first limiting portion 1111. Therefore, since the second limit part 211 is in surface contact with the first limit part 1111, it is not easy to have a large steering limit error in the long-term use process, and the use cycle is long, and it is compared with the traditional cylindrical Compared with line contact or point contact, the contact area between the second limiting portion 211 and the first limiting portion 1111 is larger, so that it is not easy to make contact with steering components (for example, steering limit device 1, steering rocker arm 2 Etc.) causing different degrees of damage such as deformation, ensuring the performance and safety of driving.

According to the steering limit assembly 100 of the embodiment of the present application, when the steering rocker arm 2 is rotated to the limit position, the second limit portion 211 is in surface contact with the first limit portion 1111. During the long-term use of the all-terrain vehicle , It is not easy to cause different degrees of damage such as excessive steering limit error and deformation of the steering contact parts, thereby ensuring driving performance and safety.

According to some embodiments of the present application, as shown in FIGS. 1 to 6 and 9 to 12, the steering limit device 1 includes a steering limit body 11, and a limit groove portion 111 is formed on the steering limit body 11 to limit the position. The two opposite side walls of the groove portion 111 respectively constitute two first limiting portions 1111. Thus, by using two opposite side walls of the limiting groove 111 to form the first limiting portion 1111 to limit the steering rocker arm 2, the limiting is reliable, and the limiting groove 111 is easy to process, which reduces the cost .

Further, referring to FIGS. 1 and 2 in combination with FIGS. 3-6 and 9-11, the limiting groove portion 111 is turned along the thickness direction of the limiting body 11 (for example, the direction perpendicular to the paper surface in FIG. 11) Through the steering limit body 11, when the second limit portion 211 and any one of the two first limit portions 1111 stop, the second limit portion 211 and the limit groove portion 111 corresponding to the steering limit body 11 Surface contact in the thickness direction. For example, in the examples shown in FIGS. 1 to 6 and 9 to 11, the limiting groove 111 penetrates the steering limiting body 11 in the front-rear direction, and since the limiting groove 111 is turned from a part of the steering limiting body 11 downward It is recessed upwardly, and the limiting groove portion 111 includes a top wall and left and right side walls connected to the left and right ends of the top wall.

Therefore, by providing the limiting groove portion 111 to penetrate the steering limiting body 11 in the thickness direction of the steering limiting body 11, it is ensured that the second limiting portion 211 is in contact with the side wall surface of the limiting groove 111. At the same time, since the two sides of the limiting groove 111 along the thickness direction of the steering limiting body 11 are open, the difficulty of assembling the steering rocker arm 2 and the steering limiting device 1 is reduced, and the assembly efficiency is improved.

Optionally, as shown in FIGS. 2-6 and 9-11, each side wall of the limiting groove 111 extends from top to bottom in a direction away from the other side wall. At this time, the two side walls of the limiting groove 111 extend from top to bottom in directions away from each other. Thus, when the second limiting portion 211 is gradually in contact with the corresponding side wall of the limiting groove portion 111, the impact force of the second limiting portion 211 on the corresponding side wall of the limiting groove portion 111 can be reduced, thereby further It is ensured that during the long-term use of the all-terrain vehicle, it is unlikely that the steering limit error is too large and the parts that are in contact with the steering are deformed to varying degrees.

Optionally, referring to Figures 9-11, the steering limit body 11 is an integrally formed sheet metal part. Therefore, since the two first limiting portions 1111 are provided on the steering limiting body 11 of the integral structure, and the steering limiting body 11 is a sheet metal piece, the left and right sides have good limiting consistency and precise steering limiting.

For example, in the example of FIGS. 1 to 8, the steering rocker arm limiting member 21 may be formed as a long strip structure extending in the front-to-rear direction, and the steering rocker arm limiting member 21 has two sides in the thickness direction (for example, The left side and the right side in FIG. 2 are adapted to abut against the corresponding side walls of the limiting groove portion 111 respectively. Therefore, the steering rocker arm limiting member 21 has a simple structure, is easy to implement, and is convenient to operate.

Further, a groove 212 is formed on each side surface of the steering rocker arm limiting member 21, and the first limiting portion 1111 contacts the inner wall surface of the groove 212 when the steering rocker arm 2 rotates to the limit position. Therefore, the steering rocker arm 2 has a steering space during the steering process, and the inner wall of the groove 212 can play a good limiting role on the first limiting portion 1111.

Optionally, the groove 212 is formed at an end of the steering rocker arm limiter 21 (for example, any end in the front-rear direction). Therefore, the structure of the entire steering limit assembly 100 can be made more compact.

Optionally, as shown in FIGS. 1 and 2, the thickness of the steering rocker arm limiting member 21 gradually decreases from bottom to top. Therefore, the thickness of the lower part of the steering rocker arm limiter 21 is relatively thick, which can improve the connection strength between the steering rocker arm limiter 21 and other components of the steering rocker arm 2, and it is less likely to cause excessive steering limit errors. ; The thickness of the upper part of the steering rocker arm limiting member 21 is relatively thin, when the steering rocker arm limiting member 21 is initially in contact with the first limiting portion 1111, it can produce a certain deformation to buffer the steering rocker arm limiting member 21 The impact force of the first limit part 1111, when the steering rocker arm limit part 21 and the first limit part 1111 are not moving, the upper part of the steering rocker arm limit part 21 returns to the initial state, so that after long-term use, the steering The rocker arm limiter 21 and the first limiter 1111 are not easily deformed or damaged, which prolongs the service life of the steering limiter assembly 100 and further ensures driving performance and safety.
