Description

Technical Field

[0001] The utility model relates to the technical field of motorcycles, in particular to a CBS arrangement structure and a motorcycle. Background Art

[0002] The CBS of a vehicle refers to the linkage braking system, which can achieve simultaneous braking of the front and rear wheels with a single hand or foot, and reasonably distribute the braking force of the front and rear wheels, thereby achieving higher braking efficiency, reducing the braking distance of the vehicle, and ensuring that the high-speed vehicle stops safely, quickly and smoothly. In actual driving, the CBS braking system can help the driver better control the vehicle and improve driving safety. Compared with the traditional braking system, the CBS braking system can better distribute the braking force of the front and rear wheels, making the vehicle more stable when braking. In addition, the CBS braking system can also provide a more sensitive braking effect, thereby shortening the braking distance of the vehicle.

[0003] At present, in the existing CBS motorcycles with front disc and rear drum, the conventional arrangement method is to connect the rear brake arm, the rear brake rod and the linkage mechanism. The linkage mechanism generally includes a conversion mechanism and an adjuster assembly. The conversion mechanism and the adjuster assembly are relatively large in size, so that the front disc and rear drum CBS needs a large space near the rear brake arm to configure the linkage mechanism. As a result, the above arrangement method will be limited by space and the structure is relatively complicated. CBS cannot be directly installed on some motorcycles with compact space unless a new mold is opened. However, opening a new mold will result in a relatively large investment and high cost, which is difficult for consumers to accept.

[0004] Therefore, how to optimize the linkage mechanism, reduce the volume of the linkage mechanism of the front disc and rear drum CBS, occupy less space, so that it is no longer affected by the problem of insufficient space for the rear brake linkage and cannot be arranged, and no additional new mold is required, thus reducing costs. Utility Model Content

[0005] In view of this, the utility model provides a CBS arrangement structure, which can reduce the volume space of the front disc and rear drum CBS proportional distribution linkage mechanism, and no longer suffer from the problem of insufficient rear brake linkage space resulting in the inability to arrange or high investment; the second purpose of the utility model is to provide a motorcycle including the above-mentioned CBS arrangement structure.

[0006] The utility model provides a CBS arrangement structure adopting the following technical solution:

[0007] A CBS arrangement structure includes a vehicle body and a rear brake pedal, wherein the vehicle body is provided with a front brake structure and a rear brake structure, and the vehicle body is provided with a rear brake assembly for rotation. The rear brake pedal can be operated to drive the rear brake assembly to rotate, and the rear brake assembly is provided with a rear brake rod and a linkage mechanism, and the linkage mechanism includes a linkage cable, and the linkage cable is connected to the front brake structure.

[0008] Optionally, the rear brake assembly includes a rear brake arm, and the linkage mechanism also includes a proportional distribution lug, which is arranged on the rear brake arm, and one end of the linkage cable is arranged on the proportional distribution lug, and the other end is connected to the front brake mechanism.

[0009] Optionally, the proportional distribution lug has a plurality of mounting portions, and the linkage cable is arranged at the mounting portions at different positions so as to adjust the pulling ratio of the linkage cable.

[0010] Optionally, the rear brake assembly also includes a rear brake crank arm, which is coaxially arranged on the rear side of the rear brake arm, and the rear brake crank arm is used to be connected to the rear brake pull rod, and the rear brake crank arm is driven to rotate synchronously when the rear brake arm rotates.

[0011] Optionally, the front brake mechanism includes a front disc brake upper pump, a front disc brake lower pump, a front disc brake disc and a front brake pad. The front disc brake upper pump is connected to the front disc brake lower pump through an oil pipe. The front disc brake upper pump drives the front disc brake lower pump through the oil pipe to squeeze the front disc brake disc through the front brake pad to complete front wheel braking.

[0012] Optionally, the rear brake mechanism includes a rear brake, a rear disc brake disc and a rear brake pad, and the rear brake pull rod operates the rear brake to squeeze the rear disc brake disc through the rear brake pad to complete rear wheel braking.

[0014] In order to achieve the above second purpose, the present invention also provides a motorcycle, which includes any one of the above CBS arrangement structures. Since the above CBS arrangement structure has the above technical effects, the motorcycle having the CBS arrangement structure should also have corresponding technical effects.

DETAILED DESCRIPTION

[0020] The following describes the embodiments of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0021] The following is combined with Figure 1-2 The utility model is described in further detail.

[0022] The embodiment of the utility model discloses a CBS arrangement structure.

[0023] Reference Figure 1 and Figure 2A CBS arrangement structure includes a vehicle body 10 and a rear brake pedal 19. The vehicle body 10 is provided with a front brake structure and a rear brake structure. The vehicle body 10 is provided with a rear brake assembly for rotation. The rear brake pedal 19 can be operated to drive the rear brake assembly to rotate. The rear brake assembly is provided with a rear brake rod 3 and a linkage mechanism. The linkage mechanism includes a linkage cable 9. The linkage cable 9 is connected to the front brake structure. When the rear brake pedal 19 drives the rear brake assembly to rotate, a part of the braking force pulls the rear brake rod 3 to drive the rear brake mechanism to brake the rear wheel 1, and the other part of the braking force is transmitted to the linkage mechanism to make the linkage cable 9 drive the front brake mechanism to brake the front wheel 17. The purpose of braking the front wheel 17 and the rear wheel 1 at the same time is achieved by setting the linkage mechanism, thereby improving the braking efficiency and increasing the driving safety. The linkage mechanism has a streamlined structure and is suitable for arranging a CBS system for motorcycles with insufficient space. The structure is simple, reliable, and requires little investment.

[0024] The vehicle body 10 adopts the motorcycle body of the prior art, and is equipped with a front wheel 17 and a rear wheel 1. The front wheel 17 is installed at the front of the motorcycle through a front fork and a front shock absorber 18, and its main function is to absorb the vibration of the road surface, maintain the stability and stability of the vehicle during driving, and prevent the vehicle from losing control. The rear wheel 1 is installed at the rear of the motorcycle through a rear flat fork 4, which plays the role of fixing the rear wheel 1, bearing the pressure of the vehicle body and maintaining stability.

[0025] In this embodiment, the rear brake assembly includes a rear brake arm 20, and the linkage mechanism also includes a proportional distribution lug 8, which is arranged on the rear brake arm 20. One end of the linkage cable 9 is arranged on the proportional distribution lug 8, and the other end is installed on the vehicle body 10 and connected to the front brake mechanism. The rear brake pedal 19 is fixedly arranged on the rear brake arm 20, and the longitudinal section of the rear brake arm 20 is approximately C-shaped. The front end of the rear brake arm 20 is rotatably matched with the rear brake pedal 19, and the rear end is rotatably matched with the main frame shaft 7 and arranged on the vehicle body 10. When the rear brake pedal 19 is stepped on, the rear brake pedal 19 is driven to rotate along the axial direction of the main frame shaft 7.

[0026] In this embodiment, the proportional distribution lug 8 has a plurality of mounting portions. Specifically, the mounting portions may be arranged at intervals along the vertical direction, or may be arranged at intervals along the circumferential direction of the main station frame axis 7. The pulling ratio of the linkage cable 9 can be adjusted by setting the mounting portions of the linkage cable 9 at different positions. That is, when the rotation angle of the proportional distribution lug 8 is the same, the degree of elongation of the linkage cable 9 is different due to the different installation positions of the linkage cable 9, thereby realizing the proportional distribution adjustment of the linkage cable 9, which can adapt to the stretching length of the linkage cable 9 required by different vehicle models and improve the applicability.

[0027] In this embodiment, the rear brake assembly further includes a rear brake crank arm 6, the front end of which is coaxially arranged at the rear side of the rear brake arm 20 through the main frame shaft 7, and the rear brake crank arm 6 is used to be connected with the rear brake pull rod 3, and the rear brake arm 20 rotates while driving the rear brake crank arm 6 to rotate synchronously. A rear brake return spring 5 is arranged on the rear brake crank arm 6, and the rear brake return spring 5 is used to apply a backward preload force to the rear brake crank arm 6.

[0028] In this embodiment, the front brake mechanism includes a front disc brake upper pump 12, an upper pump linkage mechanism 13, a front disc brake lower pump 15, a front disc brake disc 16 and a front brake pad. The front disc brake disc 16 is installed on the front wheel 17. The front disc brake upper pump 12 is connected to the front disc brake lower pump 15 through an oil pipe. The upper pump linkage mechanism 13 has a rotating part and an automatic rebound part. The automatic rebound part rotates and resets the rotating part when the rotating part is not subjected to external force. The linkage cable 9 pulls the rotating part to rotate, and the rotating part drives the front disc brake upper pump 12 to squeeze the piston inside it during the rotation process. The upper pump linkage mechanism 13 adopts the upper pump linkage mechanism 13 of the existing technology, which will not be described one by one here. The front disc brake lower pump 15 is driven by the oil pipe to drive the front brake pad to squeeze the front disc brake disc 16 to complete the braking of the front wheel 17. Specifically, the handlebar tube 11 is installed on the vehicle body 10, the front disc brake upper pump 12 with a handle is installed on the handlebar tube 11, the front disc brake lower pump 15, the upper end of the oil pipe is connected to the front disc brake upper pump 12, and the lower end of the oil pipe is connected to the front disc brake lower pump 15. After the front disc brake upper pump 12 is pulled by the linkage cable 9, it pushes the piston in the brake upper pump, so that the brake fluid in the brake upper pump flows into the brake lower pump through the oil pipe, pushing the front brake pad to move and squeeze the front disc brake disc 16.

[0029] In this embodiment, the rear brake mechanism includes a rear brake 2, a rear disc brake disc and a rear brake pad. The rear brake lever 3 operates the rear brake 2 to squeeze the rear disc brake disc through the rear brake pad to complete the braking of the rear wheel 1. The rear brake mechanism adopts the rear brake mechanism of the prior art, which will not be described in detail here.

[0030] The utility model solves the problem that a large space is needed to configure a linkage mechanism near the rear brake arm 20 to meet the front disc and rear drum CBS. By changing the structure of the linkage mechanism, a new linkage mechanism consisting of a proportional distribution lug 8 and a linkage cable 9 is provided. While meeting the CBS function, the space required for the linkage mechanism is greatly reduced, thereby achieving the purpose of simple structure and small investment.

[0031] The utility model also provides a motorcycle, which includes the above CBS arrangement structure. Since the motorcycle adopts all the above technical solutions, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0032] This article uses specific examples to illustrate the principles and implementation methods of the utility model. The description of the above embodiments is only used to help understand the method and core ideas of the utility model. The above is only the preferred implementation method of the utility model. It should be pointed out that due to the limitations of textual expression, there are objectively infinite specific structures. For ordinary technicians in this technical field, without departing from the principle of the utility model, they can make some improvements, embellishments or changes, and can also combine the above technical features in an appropriate manner; these improvements, embellishments, changes or combinations, or the direct application of the concept and technical solution of the utility model to other occasions without improvement, should be regarded as the protection scope of the utility model.
