Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to an all-terrain vehicle. Background Art

[0002] An all-terrain vehicle (ATV) is a vehicle that can travel on various complex terrains such as beaches and grasslands. Related art discloses an ATV that uses a continuously variable transmission to connect an engine and a transmission shaft.

[0003] A continuously variable transmission generally includes a driving mechanism, a driven mechanism, and a transmission belt. The driving mechanism is connected to the engine crankshaft, the driven mechanism is connected to the transmission shaft, and the transmission belt drives the driving mechanism and the driven mechanism. Among them, the driving mechanism includes a main fixed shaft, a main fixed wheel, a main sliding wheel body, a thrust plate body, a thrust elastic member, and a positioning plate body. The main fixed wheel, the main sliding wheel body, the thrust plate body, the thrust elastic member, and the positioning plate body are sequentially arranged on the main fixed shaft along the axial direction of the main fixed shaft. The main sliding wheel body can gradually slide toward the main fixed wheel as the rotation speed of the main fixed shaft increases, so that the main sliding wheel body and the main fixed wheel jointly clamp the transmission belt to drive the transmission belt to rotate, thereby rotating the driven mechanism. When the rotation speed of the main fixed shaft decreases, the elastic force of the thrust elastic member can push the main sliding wheel body away from the main fixed wheel.

[0004] As the main sliding wheel body slides toward the main fixed wheel, the positioning plate body approaches the thrust plate body. When the main fixed shaft's rotational speed reaches a set value, the positioning plate body and the thrust plate body abut against each other, causing the main sliding wheel body to slide to its limit position. After a continuously variable transmission operates for a long time, as the frequency of contact between the positioning plate body and the thrust plate body increases, the contact surface between the positioning plate body and the thrust plate body is prone to wear and impact, which can damage and fail the active mechanism.

[0005] In view of this, the present application provides an all-terrain vehicle having a continuously variable transmission with improved active mechanism reliability.

[0006] An embodiment of the present application provides an all-terrain vehicle, comprising a frame, a body covering, a power system, a traveling system, and a continuously variable transmission.

The continuously variable transmission includes a driving mechanism, a driven mechanism, and a transmission belt. The power system is transmission-connected to the driving mechanism, the transmission belt is transmission-connected to the driving mechanism and the driven mechanism, and the driven mechanism is transmission-connected to the traveling system. The driving mechanism includes an active fixed wheel assembly, an active sliding wheel assembly, and a thrust plate assembly. The active fixed wheel assembly includes a main fixed shaft and a main fixed wheel, and the main fixed wheel is connected to the main fixed shaft.

The positioning plate body is provided with a mounting sleeve protruding toward the thrust plate body. The mounting sleeve is mounted on the main fixed shaft. The connecting sleeve is mounted on the mounting sleeve. The abutment ring is mounted on the connecting sleeve and abuts against the end wall of the mounting sleeve facing the thrust plate body. The connecting ring is mounted on the connecting sleeve and abuts against the thrust elastic member.

[0008] In some embodiments of the present application, the positioning plate body is provided with an embedding groove, and the connecting ring is embedded in the embedding groove and abuts against the bottom wall of the embedding groove.

[0009] In some embodiments of the present application, the active sliding wheel assembly also includes a positioning plate sleeve, the positioning plate sleeve is sleeved on the main fixed shaft, the positioning plate body is sleeved on the positioning plate sleeve, the positioning plate body is provided with a limiting ring, the limiting ring and the abutment ring are respectively abutted against the end walls at both ends of the positioning plate sleeve.

[0010] In some embodiments of the present application, the active mechanism further includes a one-way transmission assembly, which is disposed between the main fixed wheel and the main sliding wheel body, and is sleeved onto the main fixed shaft. The rotation direction of the main fixed shaft is predefined as the active rotation direction. After the transmission belt is connected to the one-way transmission assembly, the transmission belt can provide a torque to the main fixed shaft via the one-way transmission assembly to rotate the main fixed shaft in the active rotation direction, while the main fixed shaft cannot provide a torque to the transmission belt via the one-way transmission assembly to rotate the transmission belt in the active rotation direction.

[0011] In some embodiments of the present application, the active fixed wheel assembly further comprises an active wheel sleeve and a transmission member, wherein the active wheel sleeve is disposed between the main sliding wheel body and the main fixed wheel. The active wheel sleeve comprises an active sleeve and an active pulley disc, wherein the active pulley disc is connected to the active sleeve, and the active sleeve is connected to the main fixed shaft via a transmission member. A one-way transmission assembly is disposed on the active sleeve, and the one-way transmission assembly is disposed between the main sliding wheel body and the active pulley disc. When the transmission belt drives the active sleeve to rotate, the active sleeve can move toward the main sliding wheel body so that the active pulley disc and the main sliding wheel body respectively abut against both sides of the transmission belt.

[0012] In some embodiments of the present application, the transmission member includes a groove and a projection, one of which is provided on the main fixed shaft, and the other of which is provided on the active sliding sleeve. The projection is inserted into the groove and is capable of sliding relative to the groove along an extension direction of the groove, the extension direction of the groove being inclined relative to the axial direction of the main fixed shaft, and the active sliding sleeve is capable of rotating relative to the main fixed shaft.

[0013] In some embodiments of the present application, the active fixed wheel assembly further includes a fixed sleeve connected to the main fixed shaft and at least partially inserted into the active sliding sleeve.

[0015] In some embodiments of the present application, the active sliding wheel assembly further comprises a driving wheel bushing, which is sleeved on the main fixed shaft and disposed between the thrust plate body and the one-way transmission assembly. The main sliding wheel body slides over the driving wheel bushing, with both ends of the driving wheel bushing respectively abutting against the shoulders of the thrust plate body and the main fixed shaft, and the end of the reset elastic member away from the active sliding sleeve abutting against the driving wheel bushing.

[0016] In an embodiment of the present application, when the all-terrain vehicle is driven and moved by the power system, the main fixed wheel and the main sliding wheel body jointly clamp the transmission belt, so that the driving force of the power system is transmitted to the driven mechanism through the transmission belt, thereby rotating the travel system. When the speed of the main fixed shaft increases and the sliding wheel body drives the positioning disc body to slide toward the main fixed wheel, the positioning disc body can abut against the thrust disc body through the abutment seat to constrain the main sliding wheel body to the extreme position of sliding toward the main fixed wheel. The abutment seat separates the positioning disc body from the thrust disc body, thereby reducing wear between the positioning disc body and the thrust disc body. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0027] The following embodiments of the present application are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0028] Reference Figure 1 and Figure 2 An embodiment of the present application provides an all-terrain vehicle 100 , including a frame 11 , a body covering 12 , a power system (not shown) and a travel system 13 .

[0029] The traveling system 13 is rotatably mounted on the vehicle frame 11 . In some embodiments, the traveling system 13 includes a front wheel 131 and a rear wheel 132 . Both the front wheel 131 and the rear wheel 132 are rotatably mounted below the vehicle frame 11 and support the vehicle frame 11 .

[0030] The power system is at least partially mounted on the vehicle frame 11. In some embodiments, the power system is an engine, connected to the vehicle frame 11, and the crankshaft 14 of the power system is drivingly connected to the front wheels 131 and the rear wheels 132. In other embodiments, the crankshaft 14 may be drivingly connected to only one of the front wheels 131 and the rear wheels 132. The body panel 12 is connected to the vehicle frame 11 and is substantially located around the periphery of the vehicle frame 11. The body panel 12 covers the power system, providing a certain degree of protection for the power system.

[0031] Reference Figure 2 In some embodiments, the all-terrain vehicle 100 further includes a continuously variable transmission 15 and a gear transmission 16. The crankshaft 14 of the power system, the continuously variable transmission 15, the gear transmission 16 and the travel system 13 are sequentially connected in transmission, so that the power of the power system can be transmitted to the travel system 13 through the continuously variable transmission 15 and the gear transmission 16 in sequence to drive the travel system 13 to rotate, thereby moving the all-terrain vehicle 100.

[0032] In some embodiments, the continuously variable transmission 15 includes an active mechanism 151, a driven mechanism 152, and a transmission belt 153. The crankshaft 14 of the power system is connected to the active mechanism 151, the transmission belt 153 is connected to the active mechanism 151 and the driven mechanism 152, the driven mechanism 152 is connected to the input shaft of the gear transmission 16, and the output shaft of the gear transmission 16 is connected to the travel system 13 to transmit the torque of the crankshaft 14 to the travel system 13. The gear transmission 16 is used to further adjust the torque output by the driven mechanism 152. It can be understood that the gear transmission 16 is a component that achieves a speed change effect by meshing gears of different transmission ratios with each other. The gear transmission 16 can be a single-speed structure or a multi-speed structure. The specific structure of the gear transmission 16 has been disclosed in the relevant art and will not be described in detail in this application. In other embodiments, the gear transmission 16 can be omitted as long as the travel system 13 can obtain the required torque.

[0033] Reference Figure 2 and Figure 3In some embodiments, the active mechanism 151 includes an active fixed wheel assembly 1511, an active sliding wheel assembly 1512, and a thrust plate assembly 1513. The active fixed wheel assembly 1511 includes a main fixed shaft 1511a and a main fixed wheel 1511b. The main fixed wheel 1511b is connected to the main fixed shaft 1511a. The main fixed shaft 1511a is fixedly connected to the crankshaft 14 of the power system, so that the crankshaft 14 of the power system can drive the main fixed shaft 1511a to rotate.

[0034] In some embodiments, the main fixed wheel 1511b is connected to the main fixed shaft 1511a by die-casting. In other embodiments, the main fixed wheel 1511b can also be connected to the main fixed shaft 1511a by welding. In other embodiments, the main fixed wheel 1511b can also be integrally formed with the main fixed shaft 1511a.

[0035] Reference Figure 3 The active sliding wheel assembly 1512 is slidably disposed on the main fixed shaft 1511 a along the axial direction of the main fixed shaft 1511 a , and the active sliding wheel assembly 1512 is driven to rotate by the main fixed shaft 1511 a .

[0036] The active sliding wheel assembly 1512 includes a main sliding wheel body 1512a and a positioning plate body 1512b. Both the main sliding wheel body 1512a and the positioning plate body 1512b are slidably mounted on the main fixed shaft 1511a. The positioning plate body 1512b is located on a side of the main sliding wheel body 1512a away from the main fixed wheel 1511b. The main sliding wheel body 1512a and the positioning plate body 1512b are fixedly connected to each other, and both the main sliding wheel body 1512a and the positioning plate body 1512b can slide along the axial direction of the main fixed shaft 1511a and can rotate around the axis of the main fixed shaft 1511a. In some embodiments, the main sliding wheel body 1512a and the positioning plate body 1512b are fixedly connected by bolts. In some embodiments, the active sliding wheel assembly 1512 further includes a driving wheel bushing 1512c, which is sleeved on the main fixed shaft 1511a, and the main sliding wheel body 1512a is slidably sleeved on the driving wheel bushing 1512c, so that the main sliding wheel body 1512a is connected to the main fixed shaft 1511a through the driving wheel bushing 1512c.

[0037] The thrust plate assembly 1513 is disposed between the main sliding pulley body 1512a and the positioning plate body 1512b. The thrust plate assembly 1513 includes a thrust plate body 1513a. The thrust plate body 1513a is connected to the main fixed shaft 1511a. In some embodiments, the thrust plate body 1513a and the main fixed shaft 1511a are connected via a spline structure, enabling the thrust plate body 1513a to rotate synchronously with the main fixed shaft 1511a. The end wall of the thrust plate body 1513a, located near the main fixed pulley 1511b, abuts against the shoulder of the main fixed shaft 1511a via a driving pulley bushing 1512c.

[0038] The thrust plate assembly 1513 further includes a driving wheel nut 1513b, which is disposed on the side of the thrust plate body 1513a facing away from the main sliding wheel body 1512a and is threadedly connected to the main fixed shaft 1511a. Rotating the driving wheel nut 1513b causes the driving wheel nut 1513b to abut against the side of the thrust plate body 1513a facing away from the main sliding wheel body 1512a, thereby restricting the axial movement of the thrust plate body 1513a along the main fixed shaft 1511a.

[0039] Through the above arrangement, the thrust disc body 1513a is generally fixedly connected to the main fixed shaft 1511a. In other embodiments, the thrust disc body 1513a can be fixedly connected to the main fixed shaft 1511a by interference fit or other methods.

[0040] Reference Figure 3 and Figure 4 In some embodiments, the thrust plate body 1513a is provided with a connecting portion 1513c, and the main sliding wheel body 1512a is provided with a connecting groove 1512d on the side facing the positioning plate body 1512b. The connecting portion 1513c is inserted into the connecting groove 1512d along the axial direction of the main fixed shaft 1511a and slides with the connecting groove 1512d along the axial direction of the main fixed shaft 1511a, so that the connecting portion 1513c can limit the circumferential rotation of the main sliding wheel body 1512a along the main fixed shaft 1511a, thereby enabling the main fixed shaft 1511a to drive the main sliding wheel body 1512a to rotate. In other embodiments, the positioning plate body 1512b and the main sliding wheel body 1512a can also be fixed relative to the main fixed shaft 1511a along the circumferential direction of the main fixed shaft 1511a through other structures, as long as the positioning plate body 1512b or the main sliding wheel body 1512a can slide relative to the main fixed shaft 1511a along the axial direction of the main fixed shaft 1511a, for example, the positioning plate body 1512b or the main sliding wheel body 1512a is key-connected to the main fixed shaft 1511a.

[0041] In some embodiments, the main sliding wheel body 1512a is provided with a centrifugal block 1512e, which is disposed within the connecting groove 1512d and has one end rotatably connected to the main sliding wheel body 1512a. The thrust plate body 1513a is provided with a thrust plate roller 1513d, which is rotatably connected to the connecting portion 1513c and is located on the side of the centrifugal block 1512e facing away from the main fixed wheel 1511b. When the main fixed shaft 1511a drives the thrust plate body 1513a to rotate, the thrust plate body 1513a drives the main sliding wheel body 1512a to rotate, so that the centrifugal block 1512e is subjected to the centrifugal force and rotates in the direction away from the main fixed shaft 1511a, so that the centrifugal block 1512e abuts against the thrust plate roller 1513d and pushes the thrust plate roller 1513d, so that the main sliding wheel body 1512a is subjected to a reaction force toward the main fixed wheel 1511b, so that the main sliding wheel body 1512a moves toward the main fixed wheel 1511b, so that the main sliding wheel body 1512a and the main fixed wheel 1511b respectively abut against the two sides of the transmission belt 153, thereby driving the transmission belt 153 to rotate.

[0042] The thrust plate assembly 1513 further includes a thrust elastic member 1513e, which is disposed between the positioning plate body 1512b and the thrust plate body 1513a, with both ends of the thrust elastic member 1513e respectively abutting against the thrust plate body 1513a and the positioning plate body 1512b. When the main sliding wheel body 1512a drives the positioning plate body 1512b to slide toward the main fixed wheel 1511b, the thrust elastic member 1513e is compressed and deformed by the force, causing the thrust elastic member 1513e to exert a force on the positioning plate body 1512b along the axial direction of the main fixed shaft 1511a and away from the main fixed wheel 1511b. When the speed of the main fixed shaft 1511a decreases and the centrifugal block 1512e rotates toward the main fixed shaft 1511a, the thrust elastic member 1513e can cause the positioning plate body 1512b to drive the main sliding wheel body 1512a away from the main fixed wheel 1511b. In some embodiments, the thrust elastic member 1513e is a coil spring, and the thrust elastic member 1513e is sleeved on the main fixed shaft 1511a. In other embodiments, the thrust elastic member 1513e can also be a hydraulic mechanism or other component that can provide driving force to the positioning plate body 1512b.

[0043] Reference Figure 5In some embodiments, to reduce the weight of the continuously variable transmission 15 while ensuring its structural strength, the positioning plate body 1512b is made of aluminum, while the thrust plate body 1513a and the driving wheel nut 1513b are made of steel. When the main sliding wheel body 1512a drives the positioning plate body 1512b to slide toward the thrust plate body 1513a, the aluminum positioning plate body 1512b may contact and impact the steel driving wheel nut 1513b or the steel thrust plate body 1513a, causing wear on the aluminum positioning plate body 1512b.

[0044] Reference Figure 3 and Figure 6 The active sliding wheel assembly 1512 provided in this application further includes an abutment seat 1512f, which is sleeved around the main fixed shaft 1511a and disposed between the thrust plate body 1513a and the positioning plate body 1512b to separate the thrust plate body 1513a from the positioning plate body 1512b. Abutment seat 1512f can separate the positioning plate body 1512b from the active wheel nut 1513b and the positioning plate body 1512b from the thrust plate body 1513a, thereby reducing the possibility of wear on the aluminum positioning plate body 1512b.

[0045] In some embodiments, the material of the abutment seat 1512f is the same as that of the driving wheel nut 1513b. Since the abutment seat 1512f is always in contact with the positioning plate body 1512b, the probability of wear between the contact surfaces of the abutment seat 1512f and the positioning plate body 1512b is low, thereby reducing overall wear on the positioning plate body 1512b, the thrust plate body 1513a, the driving wheel nut 1513b, or the abutment seat 1512f. In other embodiments, the material of the abutment seat 1512f is the same as that of the positioning plate body 1512b. When the abutment seat 1512f wears to a certain extent and causes a malfunction such as abnormal noise in the continuously variable transmission 15, the malfunction can be eliminated by replacing the abutment seat 1512f, which is more cost-effective than replacing the positioning plate body 1512b. In other embodiments, the abutment seat 1512f can also be made of materials other than aluminum and steel, such as plastic.

[0046] In other embodiments, the materials of the positioning plate body 1512b and the thrust plate body 1513a may also be other materials.

[0047] In other embodiments, the material of the positioning plate body 1512b may also be the same as the material of the thrust plate body 1513a or the driving wheel nut 1513b.

[0048] In some embodiments, a mounting sleeve 1512n protrudes from the positioning plate body 1512b toward the thrust plate body 1513a. The mounting sleeve 1512n is sleeved onto the main fixed shaft 1511a to connect the positioning plate body 1512b to the main fixed shaft 1511a. The abutment seat 1512f includes a connecting sleeve 1512g, an abutment ring 1512j, and a connecting ring 1512k. The connecting sleeve 1512g is sleeved onto the mounting sleeve 1512n and is rotatable relative to the mounting sleeve 1512n about the axis of the main fixed shaft 1511a. The abutment ring 1512j is disposed on the connecting sleeve 1512g and abuts against the end wall of the mounting sleeve 1512n facing the thrust plate body 1513a. The connecting ring 1512k is disposed on the connecting sleeve 1512g and abuts against the thrust elastic member 1513e.

[0049] In some embodiments, an abutment ring 1512j is disposed on the inner circumferential wall of the end of the connecting sleeve 1512g that is closer to the thrust plate body 1513a, and a connecting ring 1512k is disposed on the outer circumferential wall of the end of the connecting sleeve 1512g that is farther from the thrust plate body 1513a. In some embodiments, the connecting sleeve 1512g, the abutment ring 1512j, and the connecting ring 1512k are integrally formed. In other embodiments, the connecting sleeve 1512g, the abutment ring 1512j, and the connecting ring 1512k may be welded to each other. The abutment ring 1512j separates the mounting sleeve 1512n from the thrust plate body 1513a, thereby reducing the possibility of direct contact between the thrust plate body 1513a or the driving wheel nut 1513b and the positioning plate body 1512b, which could cause wear on the positioning plate body 1512b.

[0050] In some embodiments, the active sliding wheel assembly 1512 further includes a positioning disk sleeve 1512m, which is sleeved on the main fixed shaft 1511a. The positioning disk body 1512b is sleeved on the positioning disk sleeve 1512m. It is understood that the mounting sleeve 1512n is sleeved on the positioning disk sleeve 1512m. The positioning disk body 1512b is provided with a limiting ring 1512p. The limiting ring 1512p and the abutment ring 1512j respectively abut on either side of the positioning disk sleeve 1512m, thereby limiting the axial movement of the positioning disk sleeve 1512m relative to the positioning disk body 1512b along the main fixed shaft 1511a, thereby ensuring a stable connection between the positioning disk sleeve 1512m and the positioning disk body 1512b. In some embodiments, the positioning disk sleeve 1512m is a self-lubricating bearing. In other embodiments, the positioning plate sleeve 1512m may be a smooth sleeve or other component capable of connecting the positioning plate body 1512b to the main fixed shaft 1511a. In other embodiments, the positioning plate sleeve 1512m may be omitted, and the mounting sleeve 1512n may be loosely fitted with the main fixed shaft 1511a to enable the positioning plate body 1512b to both rotate and slide relative to the main fixed shaft 1511a.

[0051] In some embodiments, the positioning plate body 1512b is provided with an embedding groove 1512q, and the connecting ring 1512k is embedded in the embedding groove 1512q and abuts against the bottom wall of the embedding groove 1512q. The bottom wall of the embedding groove 1512q provides support for the connecting ring 1512k, thereby reducing the risk of deformation or damage to the connecting ring 1512k.

[0052] In some embodiments, the depth of the embedding groove 1512q is greater than the thickness of the connecting ring 1512k, so that the end of the thrust elastic member 1513e near the connecting ring 1512k can be embedded in the embedding groove 1512q. The embedding groove 1512q has a limiting effect on the thrust elastic member, which can improve the stability of the abutment between the thrust elastic member 1513e and the connecting ring 1512k.

[0053] Reference Figure 3 and Figure 7 In some embodiments, the active mechanism 151 further includes a one-way transmission assembly 1514, which is disposed between the main fixed wheel 1511b and the main sliding wheel body 1512a of the active sliding wheel assembly 1512. The one-way transmission assembly 1514 is sleeved onto the main fixed shaft 1511a. For ease of description, the rotation direction of the main fixed shaft 1511a is predefined as the active rotation direction (not shown). After the main sliding wheel body 1512a slides away from the main fixed wheel 1511b, the main sliding wheel body 1512a separates from the transmission belt 153, and the transmission belt 153 moves toward the main fixed shaft 1511a and connects to the one-way transmission assembly 1514. This allows the transmission belt 153, driven by the driven mechanism 152, to provide a torque to the main fixed shaft 1511a via the one-way transmission assembly 1514, causing the main fixed shaft 1511a to rotate in the active rotation direction. However, the main fixed shaft 1511a cannot provide a torque to the transmission belt 153 via the one-way transmission assembly 1514, causing the transmission belt 153 to rotate in the active rotation direction. In some embodiments, the one-way transmission assembly 1514 is a one-way bearing. In other embodiments, the one-way transmission assembly 1514 may also be a ratchet and pawl structure or other components having such a function.

[0054] For example, when the all-terrain vehicle 100 goes downhill, the power system no longer provides power to the main fixed shaft 1511a, the rotation speed of the main fixed shaft 1511a decreases, and the main sliding wheel body 1512a moves away from the main fixed wheel 1511b. The transmission belt 153 is driven by the driven mechanism 152 and is connected to the one-way transmission component 1514. At this time, when the speed of the all-terrain vehicle 100 increases under the action of its own gravity, the walking system 13 transmits driving force to the transmission belt 153 through the driven mechanism 152. When the transmission belt 153 makes the one-way transmission component 1514 After the rotation speed of the transmission component 1514 reaches the rotation speed of the main fixed shaft 1511a, the power of the transmission belt 153 is transmitted to the main fixed shaft 1511a through the one-way transmission component 1514 to drive the crankshaft 14 to rotate, thereby forming a transmission connection between the travel system 13 and the crankshaft 14. At this time, since the power system has a damping effect, it can consume part of the force of the travel system 13, and the main fixed shaft 1511a has a braking effect on the travel system 13, thereby reducing the downhill speed of the all-terrain vehicle and realizing the downhill assist function.

[0055] Reference Figure 3 and Figure 7 In some embodiments, the active fixed wheel assembly 1511 further includes an active wheel sleeve 1511c and a transmission member 1511d. The active wheel sleeve 1511c is disposed between the active sliding wheel assembly 1512 and the main fixed wheel 1511b. The active wheel sleeve 1511c includes an active sleeve 1511e and an active pulley disc 1511f. The active pulley disc 1511f is connected to the active sleeve 1511e. The active sleeve 1511e is sleeved on the main fixed shaft 1511a. The one-way transmission assembly 1514 is connected to the active sleeve 1511e and disposed between the main sliding wheel body 1512a and the active pulley disc 1511f. The active sleeve 1511e is connected to the main fixed shaft 1511a through the transmission member 1511d, so that when the transmission belt 153 drives the active sleeve 1511e to rotate, the active sleeve 1511e can move toward the active sliding wheel assembly 1512, so that the active pulley 1511f and the main sliding wheel body 1512a are respectively in contact with the two sides of the transmission belt 153, so as to increase the friction between the transmission belt 153 and the main sliding wheel body 1512a, thereby improving the efficiency of the transmission belt 153 in transmitting power to the main fixed shaft 1511a, and improving the braking effect of the crankshaft 14 of the power system on the walking system 13.

[0056] In some embodiments, the transmission member 1511d includes a groove 1511g and a protrusion 1511j, one of which is disposed on the main fixed shaft 1511a, and the other of which is disposed on the active sleeve 1511e. In some embodiments, the active fixed wheel assembly 1511 further includes a fixed sleeve 1511k, which is connected to the main fixed shaft 1511a and at least partially inserted into the active sleeve 1511e. One of the groove 1511g and the protrusion 1511j is disposed on the outer circumferential wall of the fixed sleeve 1511k, and the other of the groove 1511g and the protrusion 1511j is disposed on the inner circumferential wall of the active sleeve 1511e. In some embodiments, the fixing sleeve 1511k is rigidly connected to the main fixed shaft 1511a, thereby securing the fixing sleeve 1511k relative to the main fixed shaft 1511a. In other embodiments, the fixing sleeve 1511k is keyed to the main fixed shaft 1511a or connected by other means, as long as the fixing sleeve 1511k can rotate synchronously with the rotation of the main fixed shaft 1511a.

[0057] Reference Figure 7 and Figure 8 Exemplarily, the fixed sleeve 1511k is disposed on the side of the one-way transmission assembly 1514 away from the main fixed pulley 1511b. A groove 1511g is formed on the outer circumferential wall of the fixed sleeve 1511k. The groove 1511g extends through the end wall of the fixed sleeve 1511k near the main fixed pulley 1511b, and the extension direction of the groove 1511g is inclined relative to the axial direction of the main fixed shaft 1511a. The inner circumferential wall of the active sliding sleeve 1511e is provided with a protrusion 1511j. The protrusion 1511j protrudes from the inner circumferential wall of the active sliding sleeve 1511e. The protrusion 1511j can be inserted into the groove 1511g along the axial direction of the main fixed shaft 1511a and can slide relative to the groove 1511g along the extension direction of the groove 1511g.

[0058] When the active sleeve 1511e rotates relative to the main fixed shaft 1511a under the drive of the one-way transmission component 1514, the protrusion 1511j can contact the inner side wall of the groove portion 1511g, so that the fixed sleeve 1511k is subjected to the axial force of the protrusion 1511j along the main fixed shaft 1511a, thereby causing the active sleeve 1511e to be subjected to a corresponding reaction force, so that the active sleeve 1511e drives the active pulley 1511f toward the main sliding wheel body 1512a. Close together so that the active pulley 1511f and the main sliding wheel body 1512a cooperate to clamp the transmission belt 153; after the active pulley 1511f and the main sliding wheel body 1512a cooperate to clamp the transmission belt 153, the fixed belt drives the active sliding sleeve 1511e to rotate. Since the protrusion 1511j contacts the inner wall of the groove 1511g, and the fixed sleeve 1511k is relatively fixed to the main fixed shaft 1511a, the active sliding sleeve 1511e can drive the main fixed shaft 1511a to rotate.

[0059] In some embodiments, the active fixed wheel assembly 1511 further includes a return spring 1511m, which connects the active sleeve 1511e and the main fixed shaft 1511a. The return spring 1511m is configured to provide a force to the active sleeve 1511e axially along the main fixed shaft 1511a and toward the main fixed wheel 1511b. In some embodiments, the return spring 1511m comprises a coil spring. The return spring 1511m is sleeved within the fixed sleeve 1511k, with its ends respectively contacting the active sleeve 1511e and the active wheel bushing 1512c, thereby connecting the return spring 1511m to the active sleeve 1511e and the main fixed shaft 1511a. When the active sleeve 1511e approaches the main sliding wheel body 1512a, the reset elastic member 1511m is compressed and deformed; when the force of the transmission belt 153 on the one-way transmission component 1514 decreases, it can be understood that the rotation speed of the one-way transmission component 1514 is less than the rotation speed of the main fixed shaft 1511a, the reset elastic member 1511m can drive the active sleeve 1511e to move toward the main fixed wheel 1511b, so that the transmission belt 153 is separated from the main sliding wheel body 1512a, thereby reducing the probability of the transmission belt 153 being worn due to the rotation of the main sliding wheel body 1512a relative to the transmission belt 153.
