Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to a motorcycle. Background Art

[0002] The brake oil pipe of a motorcycle is used to connect the brake master cylinder and the brake actuator. By operating the brake lever connected to the brake master cylinder, the brake fluid in the brake oil pipe is compressed, causing the brake fluid to flow to the brake actuator, thereby causing the brake actuator to apply braking force to the motorcycle's wheel hub to achieve the braking effect.

[0003] To facilitate bending and installation within the motorcycle frame, brake hoses are typically made of rubber hoses. However, when the brake fluid within them is compressed, the hoses tend to expand and deform, increasing the brake lever's travel and resulting in a softer braking feel. Generally speaking, under the same brake fluid pressure, the greater the expansion of the hose, the longer the brake lever's travel and the softer the braking feel.

[0004] At present, in order to meet users' different soft and hard requirements for braking feel or foot feel, the expansion of the brake oil pipe is generally controlled by adjusting the material, specifications, production process, etc. of the brake oil pipe, resulting in higher production costs of the brake oil pipe. Utility Model Content

[0005] In view of this, the present application provides a motorcycle whose brake oil pipe has a low production cost.

[0006] An embodiment of the present application provides a motorcycle comprising a frame, a body panel, a running assembly, a power assembly, and a brake assembly. The body panel at least partially covers the frame. The running assembly includes a front wheel and a rear wheel, which are mounted below the frame. The power assembly is at least partially supported by the frame and is transmission-connected to the front wheel and / or the rear wheel. The brake assembly includes a brake master cylinder, an actuator, and a brake oil pipe. The brake master cylinder is supported by the frame, the actuator is connected to the front wheel or the rear wheel, and the brake oil pipe connects the brake master cylinder and the actuator. The brake oil pipe is used to transmit brake fluid. The brake oil pipe includes a rubber hose and a braided hose. One end of the rubber hose is connected to one end of the braided hose, and the interior of the rubber hose is connected to the interior of the braided hose. One of the ends of the braided hose distal to the rubber hose and the end of the rubber hose distal to the braided hose is connected to the brake master cylinder, and the other of the ends of the braided hose distal to the rubber hose and the end of the rubber hose distal to the braided hose is connected to the brake master cylinder, and the other of the ends of the braided hose distal to the rubber hose and the end of the rubber hose distal to the braided hose is connected to the actuator. When the brake fluid in the brake oil pipe is compressed, the amount of expansion and deformation per unit length of the braided hose is less than the amount of expansion and deformation per unit length of the rubber hose.

[0007] In the above-described embodiment, a rubber hose and a braided hose are interconnected to transport brake fluid. When the brake fluid is compressed, the amount of expansion and deformation per unit length of the braided hose is less than that of the rubber hose. Therefore, by using a brake hose structure with a longer braided hose and a shorter rubber hose, the overall expansion and deformation of the brake hose when the brake fluid is compressed can be reduced. Alternatively, by using a brake hose structure with a shorter braided hose and a longer rubber hose, the overall expansion and deformation of the brake hose when the brake fluid is compressed can be increased. This allows the amount of expansion and deformation of the brake hose when the brake fluid is compressed to be adjusted as needed to adjust the softness or hardness of the braking feel or pedal stroke. By using rubber hoses and braided hoses of different lengths, the softness or hardness of the braking feel or pedal stroke can be adjusted without having to adjust the materials or production processes of the braided hoses or rubber hoses, thereby reducing the production cost of the brake hose.

[0008] In some embodiments of the present application, the brake oil pipe further includes an intermediate joint, through which the rubber hose is connected to the braided hose. The intermediate joint has a first communicating hole and a second communicating hole, the first communicating hole communicating with the second communicating hole, one end of the rubber hose is connected to the intermediate joint, and the interior of the rubber hose communicates with the interior of the first communicating hole, and one end of the braided hose is connected to the intermediate joint, and the interior of the braided hose communicates with the interior of the second communicating hole.

[0009] In some embodiments of the present application, the middle joint is provided with a connection hole for inserting screws or cable ties.

[0010] In some embodiments of the present application, the intermediate joint includes a first tube and a second tube, the first tube and the second tube being detachably connected and interconnected. The inner lumen of the first tube is a first communicating hole, and the inner lumen of the second tube is a second communicating hole.

The rear wheel 32 is rotatably connected to the rear suspension assembly 12, thereby being rotatably connected to the rear of the frame 100. Both the front wheel 31 and the rear wheel 32 are used to support the frame 100 and drive the frame 100 to move. In some embodiments, the front suspension assembly 11 and / or the rear suspension assembly 12 may be omitted.

[0027] In some embodiments, the motorcycle 1000 is a two-wheeled motorcycle, having one front wheel 31 and one rear wheel 32. In other embodiments, the motorcycle 1000 may be a four-wheeled motorcycle, having two front wheels 31 and two rear wheels 32.

[0029] The vehicle body cover 200 at least partially covers the vehicle frame 100. The vehicle body cover 200 can cover the power assembly 400 to protect the power assembly 400.

[0030] The brake assembly 500 is used to brake the motorcycle 1000. In some embodiments, the brake assembly 500 includes a master cylinder 51, a brake lever 52, an actuator 53, and a brake oil pipe 55. The actuator 53 includes a brake disc 531, a brake wheel cylinder 532, and brake pads (not shown). The master cylinder 51 is supported by the frame 100, and the brake lever 52 is connected to the master cylinder 51. The brake disc 531 is connected to the wheel hub of the front wheel 31 or the rear wheel 32 of the motorcycle 1000. The brake wheel cylinder 532 is mounted on the frame 100, and the brake pad is mounted on the brake wheel cylinder 532 and is used to abut the brake disc 531 when driven by the brake wheel cylinder 532. In some embodiments, the master cylinder 51 is connected to the frame 100.

[0031] One end of the brake hose 55 is connected to the master cylinder 51, and the other end is connected to the brake wheel cylinder 532. The brake hose 55 is used to transport brake fluid. When the brake lever 52 is actuated by hand or foot, the brake lever 52 provides driving force to the master cylinder 51, thereby moving the piston of the master cylinder 51, compressing the brake fluid. The brake fluid then flows through the brake hose 55 to the brake wheel cylinder 532, causing the brake wheel cylinder 532 to drive the brake pads toward the brake disc 531, pressing against the brake disc 531. This fixes the brake disc 531 relative to the vehicle frame 100, thereby braking the corresponding front wheel 31 or rear wheel 32.

[0032] In some embodiments, the brake assemblies 500 are provided in two groups, wherein the brake discs 531 of one group of brake assemblies 500 are connected to the hub of the front wheel 31, and the brake discs 531 of the other group of brake assemblies 500 are connected to the hub of the rear wheel 32. The two groups of brake assemblies 500 brake the front wheel 31 and the rear wheel 32, respectively. In other embodiments, the brake assemblies 500 can be provided in one group, and the brake assemblies 500 each have two brake discs 531, two brake cylinders 532, and two brake pads, one of which is connected to the hub of the front wheel 31 and the other of which is connected to the hub of the rear wheel 32. Accordingly, two groups of brake oil pipes 55 are provided, each connected to the two brake cylinders 532. In this way, a single drive rod can be used to apply driving force to the master cylinder 51, so that the two brake cylinders 532 drive the corresponding brake pads to move, thereby braking the front wheel 31 and the rear wheel 32, thereby achieving the effect of a single brake assembly 500 braking the front wheel 31 and the rear wheel 32 simultaneously.

[0033] Reference Figure 1 and Figure 2In some embodiments, the brake oil pipe 55 includes a rubber hose 551 and a braided hose 552. One end of the rubber hose 551 and one end of the braided hose 552 are connected to each other and communicate with each other. The end of the rubber hose 551 away from the braided hose 552 is connected to the brake master cylinder 51, and the end of the braided hose 552 away from the rubber hose 551 is connected to the brake wheel cylinder 532. In other embodiments, the end of the braided hose 552 away from the rubber hose 551 can be connected to the brake master cylinder 51, and the end of the rubber hose 551 away from the braided hose 552 is connected to the brake wheel cylinder 532.

[0034] In some embodiments, when the brake fluid in the brake oil pipe 55 is compressed, the expansion deformation of the braided hose 552 per unit length is smaller than the expansion deformation of the rubber hose 551 per unit length.

[0035] When adjusting the braking feel or feel, the brake hose 55 structure can be configured by combining a longer braided hose 552 with a shorter rubber hose 551 to reduce the amount of expansion and deformation of the entire brake hose 55 when the brake fluid is compressed, thereby making the braking feel or feel harder. Alternatively, the brake hose 55 structure can be configured by combining a shorter braided hose 552 with a longer rubber hose 551 to increase the amount of expansion and deformation of the entire brake hose 55 when the brake fluid is compressed, thereby making the braking feel or feel softer. By using rubber hoses 551 and braided hoses 552 of different lengths, the degree of hardness or softness of the braking feel or feel can be adjusted without having to adjust the materials or production processes of braided hoses 552 or rubber hoses 551, thereby reducing the overall production cost of the brake hose 55.

[0036] In some embodiments, a protective member 5511 is provided on the outer circumference of the rubber hose 551. In some embodiments, the protective member 5511 is a sponge ring that is fitted over the rubber hose 551. In other embodiments, the protective member 5511 is a sponge pad that is adhered to and covers the outer circumference of the rubber hose 551. In other embodiments, the protective member 5511 can be made of other soft materials and provided on the outer circumference of the rubber hose 551. The protective member 5511 protects the rubber hose 551 and reduces the risk of scratching the rubber hose 551.

[0037] In some embodiments, a hose connector 5512 is connected to one end of the rubber hose 551 along its length away from the braided hose 552, and one end of the braided hose 552 along its length away from the rubber hose 551. The hose connector 5512 is used to connect to the master brake cylinder 51 or the wheel brake cylinder 532. By pre-installing the hose connector 5512 on the rubber hose 551 and the braided hose 552, the installation efficiency of the brake hose 55 can be improved.

[0038] Reference Figure 2 and Figure 3 In some embodiments, the brake fluid pipe 55 further includes an intermediate joint 553 having a first communication hole 5531 and a second communication hole 5532, with the first communication hole 5531 communicating with the second communication hole 5532. The rubber hose 551 is connected to the intermediate joint 553 at one end along its length, near the braided hose 552, and the interior of the rubber hose 551 communicates with the interior of the first communication hole 5531. The braided hose 552 is connected to the intermediate joint 553 at one end along its length, near the rubber hose 551, and the interior of the braided hose 552 communicates with the interior of the second communication hole 5532. The rubber hose 551 and the braided hose 552 are interconnected via the intermediate joint 553 to transfer brake fluid. In other embodiments, the intermediate joint 553 may be omitted, and the rubber hose 551 and the braided hose 552 may be connected and communicated with each other by fitting the end of the rubber hose 551 over the end of the braided hose 552 and tightening the rubber hose 551 with a clamp.

[0039] Reference Figure 3 In some embodiments, the intermediate joint 553 includes a first tube 5533, a second tube 5534, and a connecting seat 5535. In some embodiments, the first tube 5533 and the second tube 5534 are both fixedly connected to the connecting seat 5535, and the interior of the first tube 5533 communicates with the interior of the second tube 5534 through the connecting seat 5535. The inner cavity of the first tube 5533 is a first connecting hole 5531, and the inner cavity of the second tube 5534 is a second connecting hole 5532. In some embodiments, the first tube 5533, the connecting seat 5535, and the second tube 5534 are integrally formed.

[0040] In some embodiments, the rubber hose 551 is connected to the first tube 5533, and the braided hose 552 is connected to the second tube 5534. In some embodiments, the rubber hose 551 is sleeved over the first tube 5533 and tightened with a clamp to connect and communicate with the first tube 5533; the braided hose 552 can be connected and communicated with the second tube 5534 in the same manner.

[0041] Reference Figure 4 In some embodiments, the first tube 5533 and the second tube 5534 are both detachably connected to the connecting base 5535. In some embodiments, the connecting base 5535 is provided with a first mounting hole 5535a and a second mounting hole 5535b, the first mounting hole 5535a and the second mounting hole 5535b being in communication. The first tube 5533 is threadedly connected to the connecting base 5535 and in communication with the first mounting hole 5535a, and the second tube 5534 is threadedly connected to the connecting base 5535 and in communication with the second mounting hole 5535b.

[0042] In some embodiments, the inner walls of the first mounting hole 5535a and the second mounting hole 5535b are both provided with internal threads, and the outer walls of the first tube 5533 and the second tube 5534 are both provided with external threads. The external threads of the first tube 5533 cooperate with the internal threads of the first mounting hole 5535a, and the external threads of the second tube 5534 cooperate with the internal threads of the second mounting hole 5535b, so that the first tube 5533 and the second tube 5534 are respectively detachably connected to the connecting seat 5535.

[0043] In other embodiments, external threads may be provided on the connection base 5535 along the circumference of the first mounting hole 5535a and the second mounting hole 5535b, and internal threads may be provided on the first tube 5533 and the second tube 5534, respectively, for threadedly connecting the first tube 5533 and the second tube 5534 to the connection base 5535. In other embodiments, the first tube 5533 and the second tube 5534 may also be detachably connected to the connection base 5535 via flanges.

[0044] In other embodiments, one of the first tube 5533 and the second tube 5534 can be fixed to the connecting seat 5535, and the other of the first tube 5533 and the second tube 5534 can be detachably connected to the connecting seat 5535, so that the first tube 5533 and the second tube 5534 can be detachably connected. In other embodiments, the connecting seat 5535 can be omitted, and the first tube 5533 and the second tube 5534 can be screwed together or connected by a flange, a rotating clamping joint, or other structures, so that the first tube 5533 and the second tube 5534 can be detachably connected.

[0045] The first tube 5533 and the second tube 5534 are detachably connected to each other. The first tube 5533 can be pre-connected to one end of the rubber hose 551, and the second tube 5534 can be pre-connected to one end of the braided hose 552, so as to facilitate the connection between the rubber hose 551 and the braided hose 552, and at the same time, facilitate the matching connection of rubber hoses 551 and braided hoses 552 of different lengths as needed.

[0046] Reference Figure 4 In some embodiments, a seal 5533a is provided between the first tube 5533 and the connection base 5535, and between the second tube 5534 and the connection base 5535. The seal 5533a can improve the sealing performance of the connection between the first tube 5533 and the connection base 5535, and between the second tube 5534 and the connection base 5535, thereby reducing the possibility of brake fluid leakage.

[0047] In some embodiments, the seal 5533a is elastic. After the first tube 5533 is connected to the connection base 5535, the corresponding two sides of the seal 5533a can abut the first tube 5533 and the connection base 5535, respectively. The seal 5533a undergoes elastic deformation, thereby allowing the two sides of the seal 5533a to fully fit the first tube 5533 and the connection base 5535, respectively, which helps further improve the sealing performance of the connection between the first tube 5533 and the connection base 5535. At the same time, the elastically deformed seal 5533a exerts a reverse force on the first tube 5533, causing the threaded sidewalls of the first tube 5533 to abut against the threaded sidewalls of the connection base 5535, thereby locking the first tube 5533 and improving the stability of the connection between the first tube 5533 and the connection base 5535. The function of the seal 5533a is similar to that of the second tube 5534, and will not be described in detail here.

[0048] In some embodiments, the sealing member 5533a is annular and is sleeved onto the corresponding first tube 5533 or second tube 5534. Abutment rings 5533b are provided on the circumferential walls of both the first tube 5533 and the second tube 5534. Two sides of the sealing member 5533a abut against the connecting seat 5535 and the corresponding abutment rings 5533b, respectively. In other embodiments, using the first tube 5533 as an example, the abutment rings 5533b may be omitted, and the sealing member 5533a may be positioned between the end wall of the first tube 5533 and the connecting seat 5535. In some embodiments, the sealing member 5533a is a rubber ring. In other embodiments, the sealing member 5533a may be another elastic structural member.

[0049] In some embodiments, the intermediate joint 553 is provided with a connection hole 5535c for inserting a screw or cable tie. In some embodiments, the connection base 5535 is provided with a connection hole 5535c. In other embodiments, the first tube 5533 and / or the second tube 5534 are provided with a connection hole 5535c. When installing the brake hose 55, the intermediate joint 553 can be secured by inserting a screw or cable tie through the connection hole 5535c and then connecting it to the frame 100 of the motorcycle 1000, thereby quickly securing the brake hose 55.

[0050] In some embodiments, the braking process of the motorcycle 1000 is as follows:

[0051] The brake lever 52 is driven by hand or foot to move the piston of the master brake cylinder 51; the piston of the master brake cylinder 51 drives the brake fluid to flow, so that the brake fluid in the rubber hose 551 and the braided hose 552 is compressed, so that the brake fluid can drive the piston of the brake cylinder 532 to move; the piston of the brake cylinder 532 drives the brake pad to move toward the brake disc 531, so that the brake pad is pressed against the brake disc 531, thereby achieving braking.

[0052] When the brake fluid is compressed, the rubber hose 551 and the braided hose 552 expand and deform. Since the expansion deformation of the braided hose 552 per unit length is smaller than the expansion deformation of the rubber hose 551 per unit length, a certain length of rubber hose 551 and braided hose 552 can be selected as needed to be interconnected, and other components can be combined to make this brake oil pipe 55, which has a lower production cost.

[0053] In addition, those skilled in the art should recognize that the above embodiments are merely intended to illustrate the present application and are not intended to limit the present application. As long as they are within the spirit of the present application, appropriate changes and modifications to the above embodiments are within the scope of disclosure of the present application.
