Description

[0002] The all-terrain vehicle is commonly known as "sand vehicle", also known as "all-terrain four-wheel off-road motorcycle". The vehicle is simple and practical, and is not limited by road conditions, and has good off-road performance. In the related art, the front suspension of the all-terrain vehicle is a connecting body between the frame and the front wheel. When the all-terrain vehicle swings up and down, the connecting end of the front suspension and the frame can rotate up and down, which can alleviate the impact of the wheels on the vehicle body. The front differential is used to drive the left and right front wheels to rotate at different speeds, which is suitable for various driving states.

[0031] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more apparent and easy to understand, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0032] This application provides a front axle assembly, with reference to... Figure 1 , Figure 1 This is a schematic diagram of the front axle assembly provided in an embodiment of this application, positioned perpendicular to the vehicle's direction of travel. Figure 2 This is a top view of the front axle assembly provided in an embodiment of this application; the front axle assembly can be used on all-terrain vehicles or other vehicles.

[0033] The front axle assembly includes: a front differential 100, a left front suspension 200, and a right front suspension 300. The front differential 100 is connected to both the left and right front wheels and is used to drive the left and right front wheels to rotate at different speeds to adapt to various driving conditions. The left front suspension 200 and the right front suspension 300 are located between the left and right front wheels. The left front suspension 200 is used to connect the left front wheel to the frame, and the right front suspension 300 is used to connect the right front wheel to the frame to provide support and control, making the all-terrain vehicle more stable and safer during driving.

[0034] In the left and right directions (which represent the width of the vehicle, and the direction of travel of the vehicle is...), the width of the vehicle is... Figure 1 The direction shown, perpendicular to the plane of the paper, is perpendicular to the vehicle's direction of travel. Figure 1 In the left-right direction shown, the left front suspension 200 and the right front suspension 300 are arranged at intervals relative to each other. The left front suspension 200 has a first end and a second end opposite to each other in the left-right direction. The first end is configured to be rotatably connected to the left front wheel, and the second end is configured to be rotatably connected to the left end of the frame. Figure 1 Both the first end and the second end of the left front suspension 200 can rotate up and down. When the first end of the left front suspension 200 rotates upward, the second end of the left front suspension 200 rotates downward; and vice versa.

[0035] Similarly, the right front suspension 300 along the left and right directions ( Figure 1 The vehicle (shown in the left-right direction) has opposing third and fourth ends, the third end being configured to rotatably connect with the right front wheel, and the fourth end being configured to rotatably connect with the right end of the frame. (See reference...) Figure 1 Both the third and fourth ends of the right front suspension 300 can rotate up and down. When the third end of the right front suspension 300 rotates upward, the fourth end of the right front suspension 300 rotates downward; and vice versa.

[0036] The front differential 100 is located between the left front wheel and the right front wheel, and also between the left front suspension 200 and the right front suspension 300. The front differential 100 has a first output end and a second output end. The first output end is configured to be connected to the left front wheel via a first rotating shaft, and the second output end is configured to be connected to the right front wheel via a second rotating shaft, so as to adjust the speed difference between the left front wheel and the right front wheel when the all-terrain vehicle is in motion.

[0037] In the left and right directions ( Figure 1 In the left-right direction shown, the distance between the first output end and the left front wheel is the first distance a, the distance between the second output end and the right front wheel is the second distance b, the distance between the second end of the left front suspension 200 and the left front wheel is the third distance, and the distance between the fourth end of the right front suspension 300 and the right front wheel is the fourth distance; wherein, the first distance a is greater than the third distance, and the second distance b is less than the fourth distance. That is to say, when the front differential 100 is set between the left front suspension 200 and the right front suspension 300, the first output end of the front differential 100 is located on the outside of the left front suspension 200, while the second output end of the front differential 100 extends to the inside of the right front suspension 300.

[0038] It should be noted that the first distance 'a' and the third distance are determined based on the vertical plane where the rotation center of the left front wheel is located; similarly, the second distance 'b' and the fourth distance are determined based on the vertical plane where the rotation center of the right front wheel is located.

[0039] The front axle assembly provided in this application embodiment has a left front suspension 200 and a right front suspension 300 in the left-right direction ( Figure 1 and Figure 2The left front suspension 200 is arranged relatively spaced in the left-right direction (as shown in the diagram). It has a first end and a second end, with the first end rotatably connected to the left front wheel and the second end rotatably connected to the left end of the frame. The right front suspension 300 has a third end and a fourth end, with the third end rotatably connected to the right front wheel and the fourth end rotatably connected to the right end of the frame. A front differential 100 is disposed between the left front suspension 200 and the right front suspension 300. The front differential 100 has a first output end and a second output end. The first output end is connected to the left front wheel via a first rotating shaft, and the second output end is connected to the right front wheel via a second rotating shaft. In the left-right direction, the distance between the first output end and the left front wheel is a first distance a, the distance between the second output end and the right front wheel is a second distance b, the distance between the second end of the left front suspension and the left front wheel is a third distance, and the distance between the fourth end of the right front suspension and the right front wheel is a fourth distance. The first distance a is greater than the third distance, and the second distance b is less than the fourth distance. This design places the first output end of the front differential 100 on the outside of the left front suspension 200 and the second output end on the inside of the right front suspension 300, in order to withstand the left-right imbalance forces from the left and right front wheels and improve the stability of the all-terrain vehicle under various driving conditions.

[0040] In this embodiment of the application, the left front suspension 200 includes a left upper front suspension 201 and a left lower front suspension 202, and the left upper front suspension 201 and the left lower front suspension 202 are along the vertical direction ( Figure 1 The suspensions are arranged at intervals in the vertical direction (perpendicular to the vehicle's direction of travel). One end of the upper left front suspension 201 and one end of the lower left front suspension 202 are both configured to be rotatably connected to the left front wheel, and the other ends of the upper left front suspension 201 and the lower left front suspension 202 are both configured to be rotatably connected to the left end of the frame. The other end of the upper left front suspension 201 has a forward and backward direction (which is the forward and backward direction of the vehicle's travel). Figure 1 The first axis of rotation extends in a direction perpendicular to the paper (as shown), and the other end of the lower left front suspension 202 has a second axis of rotation extending in a front-rear direction. The first axis of rotation and the second axis of rotation are parallel.

[0041] In the left and right directions ( Figure 1 In the left-right direction shown, the distance between the first rotation axis and the left front wheel is the fifth distance d, and the distance between the second rotation axis and the left front wheel is the sixth distance c. The fifth distance d and the sixth distance c are not equal. That is to say, refer to Figure 1 The vertical plane containing the first axis of rotation does not coincide with the vertical plane containing the second axis of rotation.

[0042] In the above-mentioned embodiments of the present application, the fifth distance d can be less than the sixth distance c, so that the left lower front suspension 202 is closer to the vehicle frame, improving the support of the left front suspension 200 when the all-terrain vehicle is running in various running conditions, and making the performance of the left front suspension 200 better.

[0043] In the above-mentioned embodiments of the present application, the left upper front suspension 201 can include a first left upper front suspension 2011 and a second left upper front suspension 2012, one end of the first left upper front suspension 2011 and one end of the second left upper front suspension 2012 intersect and are both rotationally connected with the left front wheel, the other end of the first left upper front suspension 2011 and the other end of the second left upper front suspension 2012 are a certain distance apart in the front-rear direction of the vehicle running direction shown in the figure, Figure 2 the direction perpendicular to the paper shown in the figure, Figure 1 that is, from left to right Figure 2 , the angle between the first left upper front suspension 2011 and the second left upper front suspension 2012 gradually increases; the other end of the first left upper front suspension 2011 and the other end of the second left upper front suspension 2012 are both rotationally connected with the left end of the vehicle frame, and the rotation axis of the other end of the first left upper front suspension 2011 and the rotation axis of the other end of the second left upper front suspension 2012 coincide, making the rotational connection of the left upper front suspension 201 with the vehicle frame more stable.

[0044] Similarly, in the above-mentioned embodiments of the present application, the left lower front suspension 202 includes a first left lower front suspension 2021 and a second left lower front suspension 2022, one end of the first left lower front suspension 2021 and one end of the second left lower front suspension 2022 intersect and are both rotationally connected with the left front wheel, the other end of the first left lower front suspension 2021 and the other end of the second left lower front suspension 2022 are a certain distance apart in the front-rear direction of the vehicle running direction shown in the figure, Figure 2 the direction perpendicular to the paper shown in the figure, Figure 1 that is, from left to right Figure 2 , the angle between the first left lower front suspension 2021 and the second left lower front suspension 2022 gradually increases; the other end of the first left lower front suspension 2021 and the other end of the second left lower front suspension 2022 are both rotationally connected with the left end of the vehicle frame; the rotation axis of the other end of the first left lower front suspension 2021 and the rotation axis of the other end of the second left lower front suspension 2022 coincide, making the rotational connection of the left upper front suspension 201 with the vehicle frame more stable.

[0045] In the embodiments of the present application, the right front suspension 300 includes a right upper front suspension 301 and a right lower front suspension 302, the right upper front suspension 301 and the right lower front suspension 302 are a certain distance apart in the vertical direction Figure 1The suspensions shown are arranged at intervals in the vertical direction (perpendicular to the vehicle's direction of travel).

The other end of the upper right front suspension 301 has a forward and backward direction (the direction of the vehicle's travel, also known as the forward and backward direction). Figure 1 The third axis of rotation extends in a direction perpendicular to the paper (as shown), and the other end of the lower right front suspension 302 has a fourth axis of rotation extending in a front-rear direction. The third axis of rotation and the fourth axis of rotation are parallel.

[0046] In the left and right directions ( Figure 1 In the left-right direction shown, the distance between the third rotation axis and the right front wheel is the seventh distance g, and the distance between the fourth rotation axis and the right front wheel is the eighth distance f. The seventh distance g and the eighth distance f are not equal. That is to say, refer to Figure 1 The vertical plane containing the third axis of rotation does not coincide with the vertical plane containing the fourth axis of rotation.

[0047] In the above embodiments of this application, the seventh distance g is less than the eighth distance f, which makes the lower right front suspension 302 closer to the frame, improves the support force of the right front suspension 300 when the all-terrain vehicle is driving under various driving conditions, and makes the performance of the right front suspension 300 better.

[0048] In the above embodiments of this application, the upper right front suspension 301 includes a first upper right front suspension 3011 and a second upper right front suspension 3012. One end of the first upper right front suspension 3011 and one end of the second upper right front suspension 3012 intersect and are both rotatably connected to the right front wheel. The other end of the first upper right front suspension 3011 and the other end of the second upper right front suspension 3012 are along the longitudinal direction ( Figure 2 The vehicle is shown traveling in the forward and backward direction. Figure 1 The direction perpendicular to the paper shown has a certain distance, that is, from right to left ( Figure 2 As shown from right to left, the angle between the first upper right front suspension 3011 and the second upper right front suspension 3012 gradually increases; the other end of the first upper right front suspension 3011 and the other end of the second upper right front suspension 3012 are rotatably connected to the right end of the frame; and the rotation axis of the other end of the first upper right front suspension 3011 and the rotation axis of the other end of the second upper right front suspension 3012 coincide, making the rotational connection between the upper right front suspension 301 and the frame more stable.

[0049] Similarly, in the above embodiment of the present application, the right lower front suspension 302 includes a first right lower front suspension 3021 and a second right lower front suspension 3022, one end of the first right lower front suspension 3021 and one end of the second right lower front suspension 3022 intersect and are both rotationally connected with the right front wheel, the other end of the first right lower front suspension 3021 and the other end of the second right lower front suspension 3022 are spaced apart in the front-rear direction (the front-rear direction in which the vehicle travels shown in FIG. 1) of the vehicle, that is, from right to left (from right to left shown in FIG. 1), the angle between the first right lower front suspension 3021 and the second right lower front suspension 3022 gradually increases; the other end of the first right lower front suspension 3021 and the other end of the second right lower front suspension 3022 are both rotationally connected with the right end of the vehicle frame, and the rotation axis of the other end of the first right lower front suspension 3021 and the rotation axis of the other end of the second right lower front suspension 3022 coincide, so that the rotational connection of the right lower front suspension 302 with the vehicle frame is more stable.

At the same time, the released energy is converted into heat by the damper and dissipated, thereby realizing the shock absorption effect of the left front suspension 200 and the right front suspension 300 and improving the comfort of the all-terrain vehicle during driving.
