[0002] Existing locomotives are usually equipped with side supports and main supports. When using the side supports, the center of gravity will deviate from the locomotive, resulting in poor stability and reliance on flat ground. Furthermore, the steel material used in the existing side supports is prone to deformation after a period of use. When using the main support, you need to first put down the legs and step on them, then lift the rear of the locomotive 45 degrees upward and backward. The bottom of the legs of the main support easily presses on the toes, which is very laborious and unsafe. Summary of the invention

[0027] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0028] In the description of this application, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0029] In the present application, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0030] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present application. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0031] like Figures 1 to 5 As shown, in one embodiment of the present application, a support-free rear wheel of a motorcycle comprises: a first wheel 10, a second wheel 20, a mounting shaft 50, an elastic member 40 and a release and locking mechanism 30, wherein the first wheel 10 is rigidly connected to the mounting shaft 50, the second wheel 20 is connected through the mounting shaft 50 and can slide along the mounting shaft 50; the elastic member 40 is sleeved on the portion of the mounting shaft 50 between the first wheel 10 and the second wheel 20; the release and locking mechanism 30 is arranged at the end of the mounting shaft 50 outside the second wheel 20. The first wheel 10 mentioned above can be a fixed wheel, and the second wheel 20 mentioned above can be a second wheel 20.

[0032] This embodiment divides the rear wheel into two (a first wheel 10 and a second wheel 20) to complete the three supporting points required for parking the motorcycle, thereby improving parking convenience. At the same time, when one of the two rear wheels fails to work, the other can still support the motorcycle to continue traveling.

[0033] The first wheel 10 has a first tire and a first hub matched with the first tire, and the second wheel 20 has a second tire and a second hub matched with the second tire, and the first tire and the second hub are of the same size. The first tire and the second tire both have independent air tightness, and when the first tire or the second tire on one side leaks, the second tire or the first tire on the other side can provide support, thereby retaining a part of the locomotive's ability to continue traveling.

[0034] In this embodiment, the mounting shaft 50 is a square shaft. The first wheel 10 and the second wheel 20 in this embodiment use a square shaft to connect the left and right wheel hubs. Similarly, the sockets between the wheel hubs on both sides and the square shaft (axle) are also square. Since the transmission and braking of the locomotive ultimately act on the axle, the square shaft design can ensure the consistency of the movement of the first wheel 10 and the second wheel 20.

[0035] In this embodiment, the installation shaft 50 is preferably a partially hollow structure. Further, the installation side of the installation shaft 50 close to the second wheel 20 is preferably a hollow structure, and the hollow structure is used to accommodate devices such as the release locking mechanism 30.

[0036] In this embodiment, the elastic member 40 includes a spring.

[0037] The two ends of the elastic member 40 are respectively abutted (not fixedly connected) on the first wheel 10 and the second wheel 20 .

[0038] Furthermore, the locking release mechanism includes: a pedal 31, a snap spring 32 and a locking hole 33, one end of the pedal 31 is embedded in the installation shaft 50 and connected to the spring end of the snap spring 32, the snap end 321 of the snap spring 32 is matched with the locking hole 33, and the locking hole 33 is correspondingly arranged on the installation shaft 50; a rotating fulcrum 34 for the pedal 31 to rotate is also provided inside the installation shaft 50.

[0039] A limiting column 60 is further provided on the outside of the installation shaft 50, wherein the limiting column 60 is arranged on the outside of the second wheel 20. The limiting column 60 cooperates with the locking release mechanism described above to limit the sliding stroke of the second wheel 20.

[0040] The pedal 31 has two states: a locked state (see Figures 1 to 3 The pedal 31 is in the lifted state) and released state (refer to Figure 4 and Figure 5 The pedal 31 in the figure is in a depressed state). First, the vehicle body is slightly tilted, and the pedal 31 is pressed downward, and the pedal 31 rotates along the rotation fulcrum 34, and the spring lock buckle connected thereto is externally applied and disengaged from the locking hole 33 on the mounting shaft 50. At this time, the second wheel 20 slides to the left (the installation direction of the locking release mechanism) along the mounting shaft 50 under the elastic force of the elastic member 40, thereby completing the separation of the second wheel 20 from the first wheel 10.

[0041] According to the above structure, the operation method for reaching the closed locking state from the above-mentioned separation state is to first slightly tilt the body of the vehicle to make the second wheel 20 leave the ground, step one foot on the second hub of the second wheel 20 and apply force in the direction of the first wheel 10, at this time, the elastic member 40 converges and compresses under the action of external force until the limit point is on the inner side of the locking spring buckle, and then lift the pedal 31 with the toes, and the spring lock buckle falls into the locking hole 33, thereby completing the combined locking of the first wheel 10 and the second wheel 20.

[0042] The snap spring 32 and the locking hole 33 are interference fit, that is, the snap spring 32 needs additional force to fall into the locking hole 33 and to be separated from the locking hole 33. The additional force should ensure the stable locking effect and should not be too strenuous. In combination with the operation mode of stepping on the foot, the reference value is about 50 to 80 Newtons), otherwise the corresponding state before the force is applied will be maintained. According to design requirements, the elastic member 40 needs to have the elastic force to push the second wheel 20 out when it is slightly off the ground. There is no specific requirement for the size of this elastic force, which is related to many factors, such as the overall weight of the second wheel 20, the friction coefficient when the square shaft and the wheel hub slide, the angle at which the second wheel 20 is off the ground, etc. However, according to the average size and weight of most existing rear wheels of motorcycles, the compression elastic force of the elastic member 40 needs to be about 50 to 80 Newtons, that is, an external force of about 50 to 80 Newtons needs to be applied when the rear wheels are combined.

[0043] In actual use, in order to make the second wheel 20 pop out, it is necessary to slightly tilt the vehicle body to make the second wheel 20 leave the ground, so that the wheel can be smoothly popped out while overcoming the friction of the ground.

[0044] like Figures 6 to 9 As shown, in another embodiment of the present application, a locomotive M includes the above-mentioned support-free locomotive rear wheel.

[0045] Among them, regarding the structural features of the above-mentioned support-free motorcycle rear wheel, please refer to the detailed description above and will not be repeated here.

[0046] Among them, Figure 6 and Figure 7 , which shows the structural diagram of the locomotive when the rear wheels are separated; Figure 8 and Fig. 9 The diagram shows the structure when the rear wheel of the locomotive is closed.

[0047] The present application divides the rear wheel of the locomotive into two parts to complete the three supporting points (front wheel and two rear wheels) required for parking the locomotive, thereby improving the convenience of parking. At the same time, when one of the two rear wheels fails to work, the other can still support the locomotive to continue running. In addition, the installation shaft in the present application adopts a square shaft design, which can effectively ensure that the two rear wheels always keep the same movement. Therefore, the present application has a good market application prospect.

[0048] The above embodiments are only used to illustrate the technical solution of the present application but not to limit it. The present application is described in detail with reference to the preferred embodiments. It should be understood by those skilled in the art that the technical solution of the present application can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present application, and should be included in the scope of the claims of the present application.
