Fifth mounting point 1311g is for connecting knuckle 135 and sixth mounting point 1311h is for connecting frame 11.

As shown in fig. 4, as one implementation, the shortest distance between the third mounting point 1311c and the fourth mounting point 1311d is L1, i.e., the distance between the two mounting points of the upper rocker arm 1311a is L1. The shortest distance between the fifth mounting point 1311g and the sixth mounting point 1311h is L2, i.e., the distance between the two mounting points of the lower rocker arm 1311b is L2. The ratio of L1 to L2 is 0.5 or more and 1.15 or less. Specifically, the ratio of L1 to L2 is 0.6 or more and 1.1 or less. In this embodiment, the ratio of L1 to L2 is 0.7 or more and 1 or less. Through the arrangement, in the jumping process of the first traveling wheel 121, the structural relationship between the upper rocker arm 1311a and the lower rocker arm 1311b and the setting of the mounting points change the camber angle of the first traveling wheel 121 to the negative direction, which is beneficial to improving the tire grip force when the all-terrain vehicle 100 is over-bent, and simultaneously changes the caster angle to the positive direction, which is beneficial to increasing the aligning moment of the first traveling wheel 121, thereby being beneficial to improving the steering performance of the all-terrain vehicle 100. Here, the caster angle refers to an angle at which the kingpin axis is inclined toward the vehicle body inner side when the first traveling wheel 121 is viewed from the front-rear direction of the all-terrain vehicle 100.

The maximum distance between the first position and the initial position is the upward jump path L3 of the traveling assembly 12, and the maximum distance between the second position and the initial position is the downward jump path L4 of the traveling assembly 12. The ratio of L3 to L4 is 1 or more and 10 or less. Specifically, the ratio of L3 to L4 is 2 or more and 9 or less. In this embodiment, the ratio of L3 to L4 is 3 or more and 8 or less. Through the arrangement, the wheel jump travel can be controlled within a certain range, so that good passing performance of the all-terrain vehicle 100 is ensured and comfort of the all-terrain vehicle 100 can be improved. The connecting line between the left and right wheel centers when the walking assembly 12 is in the first position is a first wheel line, the connecting line between the left and right wheel centers when the walking assembly 12 is in the initial position is a second wheel line, and the connecting line between the left and right wheel centers when the walking assembly 12 is in the second position is a third wheel line. L3 may be a distance between the first wheel line and the second wheel line, and L4 may be a distance between the second wheel line and the third wheel line. The left and right wheel centers refer to the wheel centers of the left and right wheels of the first traveling wheel 121 or the wheel centers of the left and right wheels of the second traveling wheel 122.

As one implementation, the sum of the upward and downward jumps of the travel assembly 12 is L5, L5 being equal to the sum of L3 and L4, i.e., the wheel jump is L5. Wherein the wheel jump travel L5 refers to the maximum distance between the first position and the second position. The stroke of the first shock absorber 1312 is L6, and the stroke of the first shock absorber 1312 means that the first shock absorber 1312 is compressed to the shortest to the longest distance. The ratio of L5 to L6 is 1.1 or more and 2 or less. Specifically, the ratio of L5 to L6 is 1.2 or more and 1.9 or less. In this embodiment, the ratio of L5 to L6 is 1.3 or more and 1.8 or less. With the above arrangement, during the jump-up and/or jump-down of the traveling assembly 12, the first shock absorber 1312 can have a better stroke to uniformly absorb the impact of the road surface, so that the impact of the road surface can be effectively buffered, and the design and manufacturing process of the first shock absorber 1312 are facilitated. In the present embodiment, the rear suspension 132 includes a second shock absorber. The stroke of the second shock absorber is basically consistent with the stroke of the first shock absorber 1312, namely, the ratio of the stroke of the L5 and the stroke of the second shock absorber is a first ratio, the ratio of the stroke of the L5 and the stroke of the L6 are a second ratio, and the first ratio is consistent with the second ratio, so that the second shock absorber can have better stroke to uniformly absorb the impact of the road surface in the process of jumping up and/or jumping down the traveling assembly 12, and further, the road surface impact can be effectively buffered, and the design and the manufacturing processing of the second shock absorber are facilitated.

As shown in fig. 8, as one implementation, the frame 11 includes a lowest point S1 in the up-down direction, that is, a point S1 on the end surface of the lowermost end of the lower main beam 116. It will be appreciated that the surface of the walking assembly 12 that contacts the ground is a horizontal surface. The horizontal plane is substantially perpendicular to the up-down direction of ATV 100. The distance between the lowest point S1 and the horizontal plane is H, i.e., the distance between the lowest point S1 of the frame 11 and the ground is H. Running gear 12 has a radius R, i.e., the wheels of all-terrain vehicle 100 have a radius R. The ratio of R to H is 0.9 or more and 1.4 or less. Specifically, the ratio of R to H is 1 or more and 1.3 or less. Wherein R may be the radius of the first traveling wheel 121, and R may be the radius of the second traveling wheel 122. Because the distance between the lowest point of the all-terrain vehicle 100 and the ground has a great influence on the mass center height of the all-terrain vehicle 100, through the arrangement, the operation stability of the all-terrain vehicle 100 can be improved, the all-terrain vehicle 100 can have good trafficability, the wheel jump stroke is increased, and therefore the structural design and processing of the first shock absorber 1312 and the second shock absorber are facilitated.

Through the arrangement, the fixed positions of the cables and/or the pipelines of the all-terrain vehicle 100 can be separated into two fixed positions which are not mutually influenced, so that the arrangement of the cables and/or the pipelines of the all-terrain vehicle 100 is more reasonable, and the space utilization rate of the all-terrain vehicle 100 is improved. In addition, by the above arrangement, additional cable and/or duct securing structures may be reduced, thereby improving the compactness of the ATV 100 by integrating the cable and/or duct securing structures. In the present embodiment, the first and second fixing spaces 1531d and 1531e may communicate with each other, and the first and second fixing spaces 1531d and 1531e may be provided independently of each other.

As one implementation, the second locking piece 1531b includes a first fixing portion 1531f and a second fixing portion 1531g. The first fixing portion 1531f is at least partially disposed on an upper side of the second fixing portion 1531g. The first fixing portion 1531f and the second fixing portion 1531g are integrally formed. The first fixing portion 1531f and the first locking member 1531a form a first fixing space 1531d. The second fixing portion 1531g and the third locking member 1531c are formed with a second fixing space 1531e. The first fixing space 1531d extends substantially in the front-rear direction of the all-terrain vehicle 100, and the second fixing space 1531e extends substantially in the front-rear direction of the all-terrain vehicle 100.

Specifically, the first fixing portion 1531f is formed with a first accommodating groove, and the first locking member 1531a is a fixing plate having a first thickness. The first thickness can be continuously adjusted according to actual requirements. In the up-down direction of the all-terrain vehicle 100, the opening of the first accommodation groove is provided upward. ATV 100 includes a projection plane 103 perpendicular to the fore-aft direction. The projection of the lowermost end of the first locking member 1531a on the projection plane 103 in the front-rear direction is a ninth projection line, and the projection of the lowermost end of the groove bottom of the first accommodating groove on the projection plane 103 in the front-rear direction is a tenth projection line. The distance between the ninth projection line and the tenth projection line is a first distance and the maximum width of the cable and/or conduit of ATV 100 is a second distance, the first and second distances being substantially coincident. Wherein the maximum width of the cable and/or conduit of ATV 100 refers to the width perpendicular to the axial direction of the cable and/or conduit. Through the above arrangement, the cable and/or the pipe of the all-terrain vehicle 100 can be better arranged in the first fixing space 1531d, so that stable clamping of the cable and/or the pipe of the all-terrain vehicle 100 is realized. In the present embodiment, the first receiving groove is substantially formed with a semi-cylindrical space, and the cable and/or the pipe of the all-terrain vehicle 100 is substantially cylindrical, so that the fixation of the cable and/or the pipe of the all-terrain vehicle 100 can be more stable.

Specifically, the second fixing portion 1531g is formed with a second accommodating groove, and the third locking member 1531c is formed with a third accommodating groove. Along the up-down direction of the all-terrain vehicle 100, the opening of the second accommodation groove is disposed downward, and the opening of the third accommodation groove is disposed upward. The projection of the uppermost end of the bottom of the second accommodation groove on the projection plane 103 in the front-rear direction is an eleventh projection line, the projection of the lowermost end of the bottom of the third accommodation groove on the projection plane 103 in the front-rear direction is a twelfth projection line, and the distance between the eleventh projection line and the twelfth projection line is a third distance. The third distance and the second distance are substantially identical. Through the above arrangement, the cable and/or the pipe of the all-terrain vehicle 100 can be better arranged in the second fixing space 1531e, so that stable clamping of the cable and/or the pipe of the all-terrain vehicle 100 is realized. In the present embodiment, the second receiving groove is formed with a substantially semi-cylindrical space, and the third receiving groove is formed with a substantially semi-cylindrical space, that is, the second fixing space 1531e is a substantially cylindrical space. The cables and/or pipes of ATV 100 are substantially cylindrical, thereby allowing for more stable securement of the cables and/or pipes of ATV 100.

In this embodiment, the first clamping member 1531a, the second clamping member 1531b and the third clamping member 1531c are provided with the reinforcing portion 1531m, the reinforcing portion 1531m and the first clamping member 1531a are integrally formed, the reinforcing portion 1531m and the second clamping member 1531b are integrally formed, and the reinforcing portion 1531m and the third clamping member 1531c are integrally formed, thereby facilitating the processing of the first main body 1531. The reinforcement portion 1531m is configured to reinforce the first clamping member 1531a, the second clamping member 1531b, and the third clamping member 1531c, thereby improving the structural strength of the first clamping member 1531a, the second clamping member 1531b, and the third clamping member 1531c, and improving the connection stability of the cable and/or the pipe of the all-terrain vehicle 100.
