[0128] The present application provides a motorcycle, as shown in Figure 1 and Figure 2 The motorcycle comprises a frame 1, a suspension system 8, a wheel 5, a power system and a control system 6. The wheel 5 is connected to the frame 1 through the suspension system 8, and the power system and the control system 6 are at least partially arranged on the frame 1. Among them, the wheel 5 comprises a front wheel 5 and a rear wheel 5. The suspension system 8 comprises a front suspension and a rear suspension, and the front wheel 5 is connected to the frame 1 through the front suspension, and the rear wheel 5 is connected to the frame 1 through the rear suspension. The power system is arranged on the frame 1 and is used to provide power for the operation of the motorcycle. At least one of the front wheel 5 and the rear wheel 5 is drivingly connected to the power system. The control system 6 is electrically connected with the power system and is used to control the operation of the motorcycle.

[0129] The frame 1 of the motorcycle is the main body structure of the motorcycle, and carries various modules such as the engine 7, the fuel tank 3, the suspension, the instrument, etc. The frame 1 of the existing motorcycle is generally of an integrated structure, and has a large overall weight, which needs to be formed by welding with a welding tool. Due to the existence of welding thermal stress, it is difficult to control the size of the frame 1, and the tail of the frame 1 is twisted, and the size is deviated. Moreover, due to the large strength of the frame 1, the size deviation caused by the thermal stress cannot be corrected, which affects the assembly effect of the whole vehicle.

[0130] Therefore, as shown in the drawings, Figures 3 to 8 the embodiment provides a motorcycle 100, and the frame 1 of the motorcycle 100 comprises a first material piece and a second material piece. The first material piece is provided as a main frame 11 and an auxiliary frame 12, and the second material piece is provided as a tail frame 13. The second material piece is at least partially exposed from the body of the motorcycle. The two ends of the auxiliary frame 12 are connected with the main frame 11 and the tail frame 13 through bolts respectively.

[0131] In the embodiment, the frame 1 of the motorcycle is sequentially divided into three parts from the head to the tail, namely the main frame 11, the auxiliary frame 12 and the tail frame 13. The main frame 11 can carry components such as the front suspension, the engine 7 and the fuel tank 3. The auxiliary frame 12 can be used to carry components such as the cushion and the rear suspension. The tail frame 13 can be used to carry components such as the storage box and the lamp holder, or can be free of components. The main frame 11, the auxiliary frame 12 and the tail frame 13 can be respectively manufactured. When the main frame 11, the auxiliary frame 12 and the tail frame 13 are manufactured, welding tools with relatively small sizes can be used to form the shapes, which greatly simplifies the manufacturing process, simplifies the structure of the welding tool, avoids the problems of long welding tool, complex structure and high tool cost.

In addition, through the bolt connection mode, the main frame 11, the auxiliary frame 12 and the tail frame 13 can be quickly combined according to different types of vehicles, and the development cycle of the whole vehicle is shortened. Since the main frame 11, the auxiliary frame 12 and the tail frame 13 are respectively manufactured, the volume of the main frame 11, the auxiliary frame 12 and the tail frame 13 is relatively small, and the flexibility of packaging, turnover and transportation of the main frame 11, the auxiliary frame 12 and the tail frame 13 is realized.

The triangular structure can improve the stability of the auxiliary frame 12 structure and improve the structural strength, and can avoid deformation of the auxiliary frame 12 during assembly or bearing.

The connection positions of the first auxiliary beam 121 and the second auxiliary beam 122 on the third auxiliary beam 123 are close to each other, so that the first auxiliary beam 121 and the second auxiliary beam 122 can form two sides of a triangle, and a second connecting beam 124 connected between the first auxiliary beam 121 and the second auxiliary beam 122 and closest to the third auxiliary beam 123 can form the third side of the triangle, so as to form a triangular structure between the first auxiliary beam 121, the second auxiliary beam 122 and the second connecting beam 124, thereby improving the structural reliability of the first auxiliary beam 121 and the second auxiliary beam 122 at the connection position with the third auxiliary beam 123.

The connecting member 133 can be a sheet metal structure, and the two ends of the connecting member 133 are connected to the inner sides of the first frame body 131 and the second frame body 132, which can not only strengthen the structural stability between the first frame body 131 and the second frame body 132, but also improve the texture of the motorcycle through the modeling of the first frame body 131 and the second frame body 132. The first frame body 131 and the second frame body 132 can have an arc-shaped modeling or a corner-bent modeling, which is not limited in the embodiment.

[0148] The first frame body 131 and the second frame body 132 are respectively provided with three fixing holes 14, and the three fixing holes 14 on the first frame body 131 and the three fixing holes 14 on the second frame body 132 can be distributed in a triangular shape.

Specifically, after the first auxiliary beam 121, the second auxiliary beam 122 and the third auxiliary beam 123 are respectively sleeved with the corresponding interfaces on the connecting joint 125, welding or hot melting process can be used to fix the first auxiliary beam 121, the second auxiliary beam 122, the third auxiliary beam 123 and the connecting joint 125. Thus, the connection reliability between the first auxiliary beam 121, the second auxiliary beam 122 and the third auxiliary beam 123 can be ensured.

[0152] As a specific implementation manner, the materials of the main frame 11 and the auxiliary frame 12 can be chromium-molybdenum alloy steel materials. Thus, the light weight of the main frame 11 and the auxiliary frame 12 can be realized.

[0153] In addition, the material of the tail frame 13 can be aluminum alloy material, which can realize lightweight design on the one hand, and can also utilize the plasticity of the aluminum alloy material to facilitate the shaping of the appearance of the tail frame 13 and improve the overall quality of the motorcycle.

[0154] For the power system of the motorcycle, it generally includes an engine 7, a radiator assembly 2, an oil tank 3 and the like. The power system is integrated in the frame 1. The radiator assembly 2 is arranged between the wheel 5 and the engine 7 of the motorcycle for reducing the temperature of the engine 7. Generally, in order to improve the heat dissipation efficiency of the radiator assembly 2, a fan can be arranged on the radiator assembly 2. When the fan operates, it can take away the heat near the radiator assembly 2, improve the heat dissipation performance of the radiator assembly 2, and make the motorcycle engine 7 reach an appropriate temperature range, so as to ensure that the motorcycle works in the best state.

The radiator core 21 is connected to the auxiliary water tank 23, which is used to supply water to the radiator core 21 or to recycle excess water and air in the radiator core 21. The fan assembly 22 is disposed on the radiator core 21, and the air outlet direction of the fan assembly 22 is tilted at a set angle away from the center of the radiator core 21. That is, the air outlet direction of the fan assembly 22 is obliquely towards the outside of the vehicle body, thereby directing hot air to the outside of the vehicle body and avoiding the problem of hot air directly blowing onto the components around the radiator core 21 and causing high-temperature damage to the components. Specifically, the above-mentioned set angle can be 10° to 20°. Within this angle range, the heat dissipation efficiency can be improved. In this embodiment, 15° is preferred.

[0156] The fan assembly 22 can be one, two, three, or more. When there is only one fan assembly 22, it is difficult to achieve uniform heat dissipation around the heat sink 21. When there are three or more fan assemblies 22, the load on the heat sink 21 increases, and more energy is consumed, resulting in a disproportionate energy consumption and heat dissipation efficiency. Therefore, in this embodiment, the number of fan assemblies 22 is preferably two, with the two fan assemblies 22 respectively located at both ends of the heat sink 21. Specifically, the two fan assemblies 22 are arranged at the lower left and lower right corners of the heat sink 21, and can be symmetrically distributed, thereby achieving uniform heat dissipation around the heat sink 21 through the two fan assemblies 22.

[0157] Specifically, such as Figure 9 and Figure 10 As shown, the fan assembly 22 includes fan blades 221, a housing 222, and a motor. The motor is fixed to the housing 222, and the fan blades 221 are connected to the motor's output shaft. The heat dissipation core 21 includes a frame 212 and heat sinks 211. The heat sinks 211 are connected to the frame 212, and both the heat sinks 211 and the frame 212 have interconnected channels for coolant flow. The heat dissipation area of ​​the heat dissipation core 21 is composed of multiple parallel heat sinks 211. The housing 222 is fixed to the frame 212 and covers part of the heat sinks 211. The motor can drive the fan blades 221 to rotate via its output shaft, thereby blowing the heat from the radiator out of the vehicle body through the fan blades 221.

[0158] As a specific implementation, the cover 222 is provided with an air outlet, and a guide plate 222a is arranged in the air outlet and inclined away from the center of the heat dissipation core 21. The air outlet can be uniformly distributed on the circumference of the cover 222, or the air outlet can be distributed on part of the circumference of the cover 222. Since the guide plate 222a is inclined away from the center of the heat dissipation core 21, the hot air blown out of the air outlet can be guided out of the vehicle body, thereby avoiding the hot air being blown directly to the components near the heat dissipation core 21.

[0159] As a specific implementation, as shown in Figure 10 The cover 222 is further provided with a baffle 222b located on the side of the cover 222 close to the center of the heat dissipation core 21. Thus, the baffle 222b can block the air blown towards the center of the heat dissipation core 21, thereby avoiding the hot air flowing to the components at the position opposite to the heat dissipation core 21 and also avoiding the hot air flowing back into the heat dissipation core to participate in the next air suction cycle, which adversely affects the heat dissipation performance of the radiator.

[0160] The heat dissipation core 21 is arc-shaped, that is, the heat dissipation core 21 has a certain angle of curvature at both ends, and the curved surface faces the outside of the vehicle body. The fan assembly 22 is arranged at the curved positions of both ends of the heat dissipation core 21, thereby facilitating the fan assembly 22 to guide the heat to the outside of the vehicle body.

[0161] As a specific implementation, as shown in Figure 10 The cover 222 is provided with a mounting plate 222c, and the mounting plate 222c is provided with a fixing hole. The cover 222 is mounted on the frame 212 through the cooperation of the fixing hole and a screw, thereby facilitating the disassembly and assembly of the fan assembly 22.

[0162] As a specific implementation, as shown in Figure 12 The cover 222 is further provided with a clamping leg 222d, and the frame 212 is provided with a clamping groove 212a. The clamping leg 222d is clamped in the clamping groove 212a, thereby ensuring the reliability of the fixation of the cover 222 and the frame 212 and preventing the cover 222 from falling off.

[0163] In addition, it can be understood that the auxiliary water tank 23 is connected to the heat dissipation core 21. When the water in the heat dissipation core 21 is insufficient, the heat dissipation core 21 uses the internal negative pressure to absorb water from the auxiliary water tank 23 to realize water replenishment. When the heat dissipation core 21 has excess gas or water, the heat dissipation core 21 can discharge the excess water vapor to the auxiliary water tank 23. The auxiliary water tank 23 has a filling port 231. When the water in the auxiliary water tank 23 is insufficient, the water can be replenished through the filling port 231.

[0164] The auxiliary water tank 23 is usually arranged in the frame 1, and in order to meet the appearance requirement, the frame 1 has a plastic part shielding the filling port 231 of the auxiliary water tank 23.

[0165] As shown in the drawings, Figures 13 to 15 In the embodiment, the auxiliary water tank 23 has the filling port 231, and the frame 1 is provided with a detachable protective piece 16 matching the position of the filling port 231. The protective piece 16 is provided with a clamping protrusion 161, and the frame 1 is provided with a clamping soft pad 17 having a clamping hole, and the clamping protrusion 161 is clamped in the clamping hole.

[0166] In the embodiment, the protective piece 16 realizes a detachable mounting structure through the cooperation of the clamping protrusion 161 and the clamping hole, and only needs to be installed or detached through appropriate external force, thereby facilitating the water supplement to the auxiliary water tank 23 through the filling port 231 and facilitating the maintenance of the auxiliary water tank 23.

[0167] As shown in the drawings, Figure 15 The clamping soft pad 17 can be a I-shaped rubber soft pad, which can facilitate the fixed installation of the clamping soft pad 17 and the frame 1, and can also buffer the collision between the protective piece 16 and the frame 1, reduce the wear of the protective piece 16 and the frame 1, and prolong the service life.

[0168] It should be noted that the motorcycle engine is a high-temperature component, and the highest temperature in the combustion chamber of the engine can reach more than 2000 degrees when the engine is working, and the normal working temperature of the engine is about 85-105 degrees. If the engine overheats beyond the normal limit, the high-temperature components such as cylinder, piston, piston ring, crankshaft connecting rod, valve rocker arm, etc. will be ablated due to high temperature, small gap, poor lubrication, etc., causing serious wear. In addition, overheating of the engine will cause the temperature of the surrounding parts (such as the oil tank, air filter intake, passenger leg part) to rise.

[0169] For engine heat dissipation, the above-mentioned radiator can be used for main heat dissipation, but a part of heat will still accumulate around the nearby parts, such as the heat accumulated in the installation cover of the oil tank.

[0170] As shown in the drawings, Figures 16 to 19 In the embodiment, the power system of the motorcycle includes the oil tank 3 and a cover piece 31, the cover piece 31 is arranged outside the oil tank 3 and fixed to the frame 1, the cover piece 31 is provided with an air inlet 315 and a heat dissipation port 316, and the air inlet 315 and the heat dissipation port 316 are opposite in the length direction of the frame 1.

[0171] When the motorcycle is running, the heat generated by the engine 7 is partially accumulated in the cover 31, and the air can enter the cover 31 from the air inlet 315, and the accumulated heat in the cover 31 can be taken away from the heat dissipation port 316, thereby avoiding that the heat in the cover 31 is accumulated too much to affect the normal work of the surrounding devices. Among them, by relatively positioning the air inlet 315 and the heat dissipation port 316 in the length direction of the frame 1, the flow path of the air between the air inlet 315 and the heat dissipation port 316 can form a straight line, so that the air can quickly take away the heat from the cover 31, and the heat dissipation effect is improved.

[0172] As a specific implementation manner, as shown in Figure 16 and Figure 17 , the air inlet 315 is located on the side of the cover 31 facing the front end of the frame 1, and the heat dissipation port 316 is located on the side of the cover 31 facing the rear end of the frame 1. Therefore, when the motorcycle is running forward, the air inlet 315 can be directly exposed to the wind, thereby improving the air inlet amount of the air inlet 315 and improving the heat dissipation efficiency.

[0173] Specifically, as shown in Figures 16 to 19 , the cover 31 comprises a first protective member 311, a second protective member 312, a third protective member 313 and a heat dissipation member 314. The first protective member 311 is provided with an oil port 311b, one end of the second protective member 312 is connected to the side of the first protective member 311 facing the front end of the frame 1, and the other end of the second protective member 312 is connected to the frame 1; the third protective member 313 is arranged on both sides of the first protective member 311, the heat dissipation port 316 is arranged on the side of the third protective member 313 away from the front end of the frame 1, and the bottom of the third protective member 313 is fixed to the frame 1; the heat dissipation member 314 is arranged between the second protective member 312 and the third protective member 313.

[0174] Among them, the cover 31 forms a split assembly structure through the cooperation of the first protective member 311, the second protective member 312, the third protective member 313 and the heat dissipation member 314, the cover 31 can be assembled offline to form an assembly structure, and then the cover 31 of the assembly structure can be installed on the frame 1 as a whole, that is, only one installation process is arranged online to realize the installation of the cover 31 on the frame 1, without the need to arrange multiple processes to install multiple protective plates respectively as in the prior art, thereby saving online resources and simplifying the installation operation.

[0175] Specifically, the first protective piece 311 is the top of the cover piece 31, and the oil port 311b thereon can be matched with the oil filling port of the oil tank 3. The side of the first protective piece 311 towards the front end of the frame 1 can be connected with the second protective piece 312, and when the motorcycle is running, the wind can directly blow towards the second protective piece 312, which can be of an arc-shaped structure so as to guide the airflow towards the heat dissipation piece 314 behind the second protective piece 312, so as to facilitate the airflow to enter the inside of the cover piece 31 from the air inlet 315 of the heat dissipation piece 314, and to achieve heat dissipation. The third protective piece 313 can achieve protection of both sides of the oil tank 3, and through the cooperation and assembly of the first protective piece 311, the second protective piece 312 and the third protective piece 313, the structural reliability of the cover piece 31 can be ensured.

[0176] As shown in Figure 18 , the first protective piece 311 is provided with buckles 311a, and the first protective piece 311 is respectively clamped with the second protective piece 312 and the third protective piece 313 through the buckles 311a. Thus, the assembly between the first protective piece 311, the second protective piece 312 and the third protective piece 313 can be facilitated. It should be noted that the first protective piece 311 can be pre-assembled with the second protective piece 312 and the third protective piece 313 through the buckles 311a, and then can be tightened through screws, so as to achieve the final assembly. Thus, through the joint use of the buckles 311a and the screws, the stability of the structure of the cover piece 31 can be ensured.

[0177] Specifically, as shown in Figure 19 , the heat dissipation piece 314 can include a windward plate 314a, a first flange 314b and a second flange 314c, the first flange 314b and the second flange 314c are respectively arranged at both ends of the windward plate 314a, and the heat dissipation piece 314 is fixed to the second protective piece 312 through the first flange 314b, the heat dissipation piece 314 is fixed to the third protective piece 313 through the second flange 314c, and the air inlet 315 is arranged on the windward plate 314a.

[0178] The second protective piece 312 and the third protective piece 313 can be connected through the heat dissipation piece 314, that is, the heat dissipation piece 314 can not only serve as a connection between the second protective piece 312 and the third protective piece 313, but also serve as an air inlet for heat dissipation. Among them, the first flange 314b and the second flange 314c can be fixed to the inner side of the second protective piece 312, so as to achieve reliable connection and fixation, and also to make the cover piece 31 have a good appearance effect.

[0179] Among them, in order to ensure the reliability of the fixation of the heat dissipation piece 314 with the second protective piece 312 and the third protective piece 313, the second protective piece 312 is fixedly connected with the first flange 314b through screws, and the third protective piece 313 is fixedly connected with the second flange 314c through screws.

[0180] Specifically, such as Figure 19 As shown, the windward plate 314a includes a first air outlet 314a1 and a second air outlet 314a2. The angle α between the first air outlet 314a1 and the second air outlet 314a2 is set to be greater than or equal to 45° and less than or equal to 120°.

[0181] Within this angular range, sufficient space is provided between the first air outlet 314a1 and the second air outlet 314a2 to allow hot air to diffuse to the outside. It should be noted that if the angle α between the first air outlet 314a1 and the second air outlet 314a2 is less than 45°, the space between them is narrow, hindering rapid heat dissipation. This causes hot air to accumulate in the cover 31, leading to increased temperature of surrounding components and affecting normal operation. If the angle between the first air outlet 314a1 and the second air outlet 314a2 is greater than 120°, the air outlet direction of the first air outlet 314a1 and the second air outlet 314a2 will be closer to the direction perpendicular to the motorcycle's travel. When the motorcycle is moving forward, the external airflow blowing towards the wind vane 314a will blow most of the hot air near the first air outlet 314a1 and the second air outlet 314a2 back into the cover 31, forming a hot airflow vortex within the cover 31, which is not conducive to the diffusion of hot air to the outside. In this embodiment, the angle between the first air outlet 314a1 and the second air outlet 314a2 is preferably 45°, 60°, 80°, 100°, or 120°.

[0182] Specifically, such as Figure 19 As shown, the windward plate 314a has multiple mesh holes 314a3, which form an air inlet 315. By setting multiple mesh holes 314a3, the windward plate 314a can form a mesh plate. The mesh holes 314a3 can ensure that the airflow enters the cover 31 smoothly and improve the appearance of the cover 31.

[0183] Furthermore, such as Figure 19 As shown, the heat sink 314 is also provided with a connecting beam 314d, the two ends of which are fixedly connected to the first flange 314b and the second flange 314c, respectively. The connecting beam 314d can improve the stability of the heat sink 314 structure, enabling the heat sink 314 to reliably connect the second protective component 312 and the third protective component 313.

[0184] Specifically, such as Figure 16As shown, in order to ensure that the cover 31 can be reliably connected to the frame 1, the second guard 312 can be provided with three fixing positions 312a away from the first guard 311, and the fixing positions 312a are fixed to the frame 1 by screws. Of course, the number of fixing positions 312a can also be other numbers, and the specific number is subject to the condition that the cover 31 can be reliably connected to the frame 1.

[0185] The power system of the motorcycle further includes a brake system 4, wherein the brake of the motorcycle is the core component for realizing the braking of the motorcycle, which generally includes a brake caliper, the brake caliper is provided with friction plates, the wheel 5 is provided with a brake disc, and when braking, the brake caliper drives the friction plates to approach and release the brake disc, and the braking is realized through the friction between the friction plates and the brake disc. The brake is generally pre-installed on the bracket body, and after the complete assembly of the whole vehicle, the bracket body will be completely fixed in the wheel shaft axial direction and cannot move. However, since the friction plates hold the two side disc surfaces of the brake disc, the two friction plates need to be kept parallel to the brake disc, otherwise if the friction plates are in the shape of an "eight" or an inverted "eight", the friction plates will appear to be eccentrically worn, which will not only affect the braking effect and produce abnormal noise, but also reduce the service life of the friction plates.

[0186] Therefore, as shown in the Figures 20 to 22 brake system 4 of the motorcycle provided by the embodiment of the application includes a brake 41, a brake bracket assembly 43 and a brake disc 42, the brake bracket assembly 43 includes a bracket body 431, a first limiting portion 432 and a second limiting portion 433, the brake 41 is installed on the bracket body 431, the brake 41 includes two friction plates 411, the brake disc 42 is installed on the wheel shaft 51 of the wheel 5, and the two friction plates 411 are respectively located on the two sides of the brake disc 42. When the motorcycle brakes, the brake 41 can control the two friction plates 411 to contact the brake disc 42, and the braking is realized through the friction between the two friction plates 411 and the brake disc 42.

[0187] As shown in the Figures 21 to 22 brake system 4 of the motorcycle provided by the embodiment of the application includes a brake 41, a brake bracket assembly 43 and a brake disc 42, the brake bracket assembly 43 includes a bracket body 431, a first limiting portion 432 and a second limiting portion 433, the brake 41 is installed on the bracket body 431, the brake 41 includes two friction plates 411, the brake disc 42 is installed on the wheel shaft 51 of the wheel 5, and the two friction plates 411 are respectively located on the two sides of the brake disc 42. When the motorcycle brakes, the brake 41 can control the two friction plates 411 to contact the brake disc 42, and the braking is realized through the friction between the two friction plates 411 and the brake disc 42.

[0188] Due to the existence of the gap d, the bracket body 431 can move slightly axially relative to the hub 52. Specifically, if there is a slight angle between the friction plate 411 and the brake disc 42, that is, the friction plate 411 is deflected, and due to the existing bracket body 431 being fixed, during braking, the axial movement of the friction plate 411 is a certain distance, resulting in only a part of the friction plate 411 being in contact with the brake disc 42, and the other part not being in contact with the brake disc 42, which causes the friction plate 411 to be deflected during braking. For this reason, in the present application, when the friction plate 411 is deflected at a slight angle, the bracket body 431 can move axially due to the relative force between the bracket body 431 and the brake disc 42, so that when the two friction plates 411 clamp the brake disc 42, the bracket body 431 can move axially by an appropriate amount, so that the gap between the friction plate 411 and the brake disc 42 can be adjusted to fit, thereby ensuring that the deflected friction plate 411 can fully fit the brake disc 42, avoiding deflection and abnormal noise.

[0189] As a specific implementation, as shown in Figures 21 to 22 The motorcycle further comprises at least one elastic washer 44, which is arranged on one side of the bracket body 431 towards the first limiting portion 432 and / or the second limiting portion 433.

[0190] The elastic washer 44 is located between the bracket body 431 and the first limiting portion 432, or between the bracket body 431 and the second limiting portion 433. When there are two elastic washers 44, they can be located between the bracket body 431 and the first limiting portion 432, and between the bracket body 431 and the second limiting portion 433, respectively. In the present embodiment, the elastic washer 44 is preferably provided with two, which can on the one hand stabilize the bracket body 431 between the first limiting portion 432 and the second limiting portion 433 when not braking; on the other hand, when braking, the bracket body 431 moves axially to compress the elastic washer 44, and when the brake is released, the elastic washer 44 restores deformation, which can provide a certain elastic force to the bracket body 431, so that the bracket body 431 returns to the first limiting portion 432 and the second limiting portion 433, so that the deflected friction plate 411 is separated from the brake disc 42, avoiding contact between the friction plate 411 and the brake disc 42 in the non-braking state, which causes the deflection and abnormal noise of the friction plate 411. In addition, the elastic washer 44 can also avoid the rigid collision between the bracket body 431 and the first limiting portion 432 and / or the second limiting portion 433, thereby avoiding abnormal noise.

[0191] Specifically, as shown in Figures 21 to 22As shown, the first recess 431a is arranged on one side of the support body 431 towards the first limiting portion 432 and / or the second limiting portion 433, and the elastic washer 44 is installed in the first recess 431a, and the elastic washer 44 partially protrudes from the surface of the support body 431. The first recess 431a can facilitate the installation and fixation of the elastic washer 44, and the first limiting portion 432 and / or the second limiting portion 433 can block the side of the elastic washer 44 away from the first recess 431a, thereby preventing the elastic washer 44 from falling off. The part of the elastic washer 44 protruding from the first recess 431a can be elastically deformed to provide an elastic force to the support body 431, facilitate the return of the support body 431 when the brake is cancelled, and also ensure the stability of the support body 431 in the non-braking state.

[0192] As a specific implementation, as shown in Figures 21 to 22 As shown, the gap d between the support body 431 and the first limiting portion 432 and the gap d between the support body 431 and the second limiting portion 433 are set to be greater than or equal to 0.1 mm and less than or equal to 0.3 mm. Within this gap range, the angle of deflection of the friction plate 411 can be absorbed by the axial movement of the support body 431, ensuring that the friction plate 411 fully contacts the brake disc 42 and avoiding uneven wear.

[0193] If the gap d is less than 0.1 mm, the friction plate 411 cannot fully contact the brake disc 42, and if the gap d is greater than 0.3 mm, the stability of the support body 431 during operation cannot be guaranteed. In this embodiment, the gap d between the support body 431 and the first limiting portion 432 and the second limiting portion 433 is preferably 0.2 mm.

[0194] As a specific implementation, as shown in Figures 21 to 22 As shown, the hub 52 is provided with a step, the first limiting portion 432 is a first annular retainer, and the first annular retainer is sleeved on the hub 52 and abuts against the step. When installing the brake support assembly 43, the first annular retainer can be sleeved on one end of the hub 52 first, so that the first annular retainer abuts against the step, and then the support body 431 with the elastic washer 44 installed can be installed on the hub 52, so that the part of the elastic washer 44 protruding from the surface of the support body 431 abuts against the first annular retainer. Thus, the first annular retainer can limit one side of the support body 431.

[0195] As a specific implementation, as shown in Figures 21 to 22As shown, the second limiting portion 433 is a second annular stop ring, which is sleeved on the hub 52. The hub 52 is provided with a second groove 521, and the brake support assembly 43 further comprises a stop block 434, which is clamped in the second groove 521, and the side of the second limiting portion 433 away from the support body 431 abuts against the stop block 434. After the support body 431 is installed on the hub 52, the second annular stop ring can be sleeved on the hub 52, so that the second annular stop ring abuts against the elastic washer 44, and then the stop block 434 is clamped into the second groove 521, so that the stop block 434 abuts against the second annular stop ring, thereby limiting the second annular stop ring.

[0196] It can be understood that, in order to facilitate the fixed installation of the brake 41 and the support body 431, the brake 41 comprises a shell 412, and the shell 412 and the support body 431 are fixedly connected by bolts.

[0197] In addition, in order to realize the light weight of the brake support assembly 43 and the whole vehicle, the support body 431 can be provided with a lightening hole.

[0198] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the protection scope of the present application.
