[0022] In order to clearly illustrate the technical solutions of the embodiments of the utility model or the prior art, the drawings required for use in the embodiments or the prior art descriptions are briefly introduced below. Obviously, the content described below is only one embodiment of the utility model. For ordinary technicians in this field, all other embodiments obtained without creative work are within the protection scope of the utility model.

[0023] like Figure 1 A two-wheeled vehicle 100 is shown, including a frame 11, a body cover 12, a power assembly (not shown), a travel assembly 14 and a suspension assembly 15. The power assembly is arranged on the frame 11 and supported by the frame 11. The body cover 12 is at least partially arranged on the frame 11 and at least partially covers the power assembly, and is used to provide coverage and protection for the power assembly and other components of the two-wheeled vehicle 100. The travel assembly 14 includes a front wheel 141 and a rear wheel 142 that are at least partially arranged below the frame 11. The suspension assembly 15 includes a rear fork 151 that is respectively connected to the frame 11 and the rear wheel 142. One end of the rear fork 151 is rotatably connected to the frame 11, and the other end of the rear fork 151 is rotatably connected to the rear wheel 142. In order to clearly describe the two-wheeled vehicle 100 in the present application, the following are also defined. Figure 1 In the present application, the length direction of the two-wheeled vehicle 100 refers to the front, rear, left, right, top and bottom. Figure 1 In the front-to-back direction, the width direction of the two-wheeled vehicle 100 refers to Figure 1 The left and right directions in the two-wheeled vehicle 100 refer to the height direction Figure 1 The up and down directions in .

[0024] like Figure 2 and Figure 3As shown, the traveling assembly 14 further includes a rear wheel axle 143, and the rear wheel axle 143 at least partially penetrates the rear flat fork 151 and the rear wheel 142, so that a connection is formed between the rear wheel 142 and the rear flat fork 151. Specifically, the rear wheel 142 includes a connecting portion 1421, and the rear wheel axle 143 penetrates the rear flat fork 151 and the connecting portion 1421 respectively, and the rear wheel axle 143 and the rear flat fork 151 are fixedly connected, and the rear wheel axle 143 and the connecting portion 1421 are rotationally connected, and then the rear wheel 142 is rotationally connected to the frame 11 in the above manner, thereby driving the operation of the two-wheeled vehicle 100. The two-wheeled vehicle 100 provided in the present application further includes a brake assembly 16, which includes a brake pad 161 and a brake caliper 162 arranged on the rear wheel 142. Specifically, the brake pad 161 is arranged on the connecting portion 1421 and is fixedly connected to the connecting portion 1421, that is, the brake pad 161 can rotate with the rear wheel 142 when the rear wheel 142 is in motion. The brake caliper 162 is arranged on the rear wheel axle 143 and is fixedly connected to the rear wheel axle 143. Further, the brake caliper 162 also cooperates with the brake pad 161, and the brake caliper 162 can control the rotation state of the brake pad 161, thereby controlling the running state of the rear wheel 142.

[0025] like Figure 3 and Figure 4 As shown, the brake assembly 16 further includes a mounting bracket 163, and the brake caliper 162 is disposed on the mounting bracket 163 and fixedly connected to the rear wheel axle 143 through the mounting bracket 163; specifically, the mounting bracket 163 is disposed between the connecting portion 1421 and the rear fork 151, and the rear wheel axle 143 is configured to penetrate the mounting bracket 163. A longitudinal plane P1 perpendicular to the width direction of the two-wheeled vehicle 100 and passing through the width center of the two-wheeled vehicle 100 is defined. It can be understood that in order to ensure the stability of the two-wheeled vehicle 100, the rear wheel 142 is basically disposed at the width center of the two-wheeled vehicle 100, so it can be understood that the longitudinal plane P1 basically penetrates the connecting portion 1421. As an optional embodiment, the rear wheel axle 143 is provided with an abutment portion 1431 on one side of the longitudinal plane P1. Specifically, the abutment portion 1431 is located on the side of the connecting portion 1421 away from the longitudinal plane P1, and the mounting bracket 163 and the rear fork 151 abut against each other along the axial extension direction of the rear wheel axle 143.

[0026] The walking assembly 14 further includes a nut 144, which is disposed on a side of the rear fork 151 away from the longitudinal plane P1 and cooperates with the rear wheel axle 143. The nut 144 can provide a force along the axis extension direction of the rear wheel axle 143 and close to the connecting portion 1421, so that the mounting bracket 163 abuts against the abutment portion 1431 and the rear fork 151 along the axis extension direction of the rear wheel axle 143, and further, the rear fork 151 abuts against the mounting bracket 163 and the nut 144 along the axis extension direction of the rear wheel axle 143, and the circumferential movement of the mounting bracket 163 is restricted by the force of the above components along the axis direction of the rear wheel axle 143. As an optional embodiment, the rear fork 151 and the mounting bracket 163 form a clearance fit with the rear wheel axle 143 respectively. This connection method can simplify the installation process between the rear wheel axle 143, the rear fork 151 and the mounting bracket 163, and reduce the difficulty of assembly. The nut 144 is connected to the rear wheel shaft 143 by a threaded connection, so that the preload force in the axial direction of the rear wheel shaft 143 can be adjusted by the nut 144. It can be understood that as an optional embodiment, in order to make the relative positions of the components distributed in the axial direction of the rear wheel shaft 143 reasonable, a bushing 145 can also be provided on the rear wheel shaft 143. The bushing 145 can be provided between the mounting bracket 163 and the rear flat fork 151 and abut against the mounting bracket 163 and the rear flat fork 151 respectively. The bushing 145 can also be provided between the abutment portion 1431 and the mounting bracket 163 and abut against the abutment portion 1431 and the mounting bracket 163 respectively, and the bushing 145 and the rear wheel shaft 143 are also provided with a clearance fit. In the present application, the bushing 145 is provided between the mounting bracket 163 and the abutment portion 1431 and abuts against the abutment portion 1431 and the mounting bracket 163 respectively.

[0027] It can be understood that the abutment portion 1431 can be arranged on the left side of the longitudinal plane P1 or on the right side of the longitudinal plane P1. In the present application, the mounting bracket 163 and the abutment portion 1431 are both arranged on the left side of the connecting portion 1421.

[0028] like Figure 5As shown, as mentioned above, the mounting bracket 163 is respectively abutted against the components arranged on both sides of the mounting bracket 163, and the locking of the mounting bracket 163 is achieved by the preload force in the axial direction of the rear wheel axle 143. Specifically, an abutment surface 1631 is formed on the side where the mounting bracket 163 abuts against the bushing 145. In the present application, in order to maximize the contact area with the bushing 145, the abutment surface 1631 is formed as an annular structure, and the annular structure is substantially consistent with the cross-section of the bushing 145. Furthermore, this annular structure can form a uniform reinforcement effect around the hole connecting the mounting bracket 163 and the rear wheel axle 143, which can effectively avoid stress concentration at a certain place, thereby causing damage and breakage during the driving process of the two-wheeled vehicle 100. As an optional embodiment, the area of ​​the abutment surface 1631 in the present application is greater than or equal to 380mm 2 And less than or equal to 430mm 2 , the selection of this range can make the mounting bracket 163 and the bushing 145 have enough friction to realize the rotation restriction of the mounting bracket 163 in the circumferential direction. At the same time, the area of ​​the abutting surface 1631 is too large, which increases the volume and weight of the bushing 145, which is not conducive to the lightweight layout of the two-wheeled vehicle 100. In order to further increase the strength of the mounting bracket 163, a reinforcing portion 1632 is also provided on the mounting bracket 163. Specifically, the reinforcing portion 1632 is set as a reinforcing rib structure protruding to one side of the mounting bracket 163. The reinforcing portion 1632 is basically extended along the radial direction of the abutting surface 1631. Further, the reinforcing portion 1632 is also basically distributed around the circumference of the abutting surface 1631. This arrangement can effectively increase the structural strength of the mounting bracket 163 itself, and avoid the deformation and twisting of the mounting bracket 163 itself due to the circumferential rotation between the mounting bracket 163 and the rear wheel shaft 143 during the driving process of the two-wheeled vehicle 100, thereby causing the deformation or even damage of the mounting bracket 163. It is understandable that the bushing 145 can also be arranged between the mounting bracket 163 and the rear fork 151, that is, the abutting surface 1631 is located on the side of the mounting bracket 163 close to the rear fork 151. In addition, as another optional embodiment, the bushing 145 can also be arranged on both sides of the mounting bracket 163, that is, the abutting surface 1631 is arranged on both sides of the mounting bracket 163. This arrangement can remember to increase the surface contact area between the mounting bracket 163 and the rear fork 151, and further fix the mounting bracket 163 in the circumferential direction.

[0029] like Figure 6As shown, in order to further strengthen the connection between the mounting bracket 163 and the rear fork 151 and prevent the mounting bracket 163 from circumferential rotation during the driving of the two-wheeled vehicle 100, a limit block 152 cooperating with the mounting bracket 163 is further provided on the rear fork 151, and the limit block 152 is at least partially located between the mounting bracket 163 and the rear fork 151, and the limit block 152 and the rear fork 151 are fixedly connected. Furthermore, a mounting portion 1633 cooperating with the limit block 152 is provided on the mounting bracket 163, and when the mounting bracket 163 is in the installed state, the limit block 152 is at least partially located in the mounting portion 1633, and there is a clearance fit between the limit block 152 and the mounting portion 1633. This arrangement can facilitate the rapid assembly of the mounting bracket 163. It is understandable that setting an appropriate gap between the inner diameter of the mounting portion 1633 and the mounting block can facilitate the assembly of the limit block 152, but an excessively large gap makes it difficult to limit the slight deformation or displacement of the mounting bracket 163, and cannot effectively increase the rotational modal frequency and solve the abnormal noise problem. Therefore, as an optional embodiment, the installation gap between the mounting portion 1633 and the limit block 152 should be controlled to be greater than or equal to 0.1 mm and less than or equal to 0.2 mm. Specifically, the mounting portion 1633 can be set as a through hole that penetrates the mounting bracket 163 along the width direction of the two-wheeled vehicle 100, or it can be set as a mounting groove opened on one side of the limit block 152, as long as the limit of the limit block 152 can be achieved in the height direction of the two-wheeled vehicle 100. In the present application, the mounting portion 1633 is set as a mounting groove extending along the length direction of the two-wheeled vehicle 100, and the limit block 152 and the mounting groove are in surface contact.

[0030] like Figure 6 As shown, further, in order to further strengthen the stability of the connection between the mounting bracket 163 and the rear fork 151, the suspension assembly 15 also includes a fixing member 153, and the fixing member 153 is used to further fix the connection between the limit block 152 and the rear fork 151. The fixing member 153 at least partially penetrates the limit block 152 and the rear fork 151. Specifically, the fixing member 153 and the rear fork 151 are clearance-fitted, and the fixing member 153 and the limit block 152 are threadedly connected. This arrangement can further strengthen the connection between the limit block 152 and the mounting bracket, and can limit the limit block 152 in the height direction of the two-wheeled vehicle 100 through the mounting portion 1633, thereby realizing the circumferential limit of the mounting bracket 163.

[0031] The limit block 152 and the rear fork 151 can be set to be welded or connected by a connector. In order to reduce the installation process, in the present application, the limit block 152 and the rear fork 151 are welded. It can be understood that the limit block 152 and the rear fork 151 are set to be welded, so that during the assembly process, it is necessary to first complete the installation between the mounting bracket 163 and the rear fork 151 through the limit block 152, and then further install the mounting bracket 163, the rear wheel 142 and the fork through the rear wheel shaft 143, and finally install the nut 144 and apply a pre-tightening force to the mounting bracket 163 and the rear wheel 142 through the nut 144 to complete the installation. Furthermore, the mounting bracket 163 and the limit block 152 can be set on the left side of the longitudinal plane P1, or on the right side of the longitudinal plane P1, as long as the fixed installation of the mounting bracket 163 can be achieved.

[0032] It can be understood that the two-wheeled vehicle of the present application can be an electric two-wheeled vehicle or a fuel two-wheeled vehicle. As long as the brake assembly of the two-wheeled vehicle can be effectively fixed in the axial direction, it falls within the protection scope of the present application.

[0033] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the above embodiments do not limit the utility model in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the utility model.
