Description

Technical Field

[0001] The present application relates to the field of braking technology, and in particular to an anti-lock braking system and a motorcycle. Background Art

[0002] With the continuous improvement of the performance of modern motorcycles, their braking system has gradually become one of the key factors affecting driving safety. Among them, the application of ABS (Anti-lock Braking System) technology has significantly improved the driving safety of vehicles on slippery roads or in emergency braking. ABS prevents the wheels from completely locking by periodically releasing and applying braking force, thereby maintaining the vehicle's steering ability and ensuring that the driver has enough time to adjust the direction to avoid accidents.

[0003] However, using ABS alone will cause uneven braking force on the wheels, and the motorcycle will sacrifice some braking deceleration to obtain body stability during braking. In addition, the existing rear brake performance is poor, especially when the front brake fails, the deceleration provided by the rear brake during emergency braking is insufficient, which is easy to cause safety accidents. In addition, in the prior art, when the front brake or the rear brake is operated alone, the body stability is poor, and it is easy to cause tail lift or tail swing. When the front and rear brakes are operated at the same time, the asynchronism of time and force will also cause body stability problems. Utility Model Content

Detailed implementation manners

[0033] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some but not all of the embodiments of the present application.

[0035] In the description of the present application, it should also be noted that unless otherwise clearly specified and limited, the terms "set", "connect" 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 directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0036] Please refer to Figure 1 , Figure 1 , which is a schematic diagram of the motorcycle 1 provided by the embodiments of the present utility model. The present utility model provides a motorcycle 1, which includes a frame and an anti-lock braking system 10, and the anti-lock braking system 10 is connected to the frame.

[0037] Among them, based on the design concept of combined front and rear wheel braking and cross braking, the anti-lock braking system 10 can reasonably distribute the braking force to the front wheel 31 and the rear wheel 33 of the motorcycle 1, thereby making full use of the adhesion and contact area of each tire, improving the overall stability of the motorcycle 1, and ensuring the overall braking deceleration of the motorcycle 1.

[0038] On the basis of the improved stability of the anti-lock braking system 10 described above, the dynamic change range, amplitude, and frequency of the overall center of gravity of the motorcycle 1 are also correspondingly improved, greatly increasing the safety of the motorcycle 1 under various working conditions, and fully meeting the riding needs and safety guarantees of users in different scenarios.

[0039] Next, the specific structures of the various components of the anti-lock braking system 10 provided in this embodiment and the corresponding relationships between them will be described in detail. Figure 2 Schematic diagram of the anti-lock braking system 10 provided by an embodiment of the present invention, Figure 3 Another schematic diagram of the anti-lock braking system 10 provided by an embodiment of the present invention.

[0040] Please refer to Figure 2 and Figure 3 , the present application provides an anti-lock braking system 10, which includes an ABS control valve 100, a front disc brake lower pump 210 for braking the front wheel 31, a rear disc brake lower pump 230 for braking the rear wheel 33, a front disc brake upper pump 310, and a rear disc brake upper pump 330. Among them, the front disc brake upper pump 310 is connected to the front disc brake lower pump 210 and the rear disc brake lower pump 230 through the ABS control valve 100 for simultaneously braking the front wheel 31 and the rear wheel 33; the rear disc brake upper pump 330 is connected to the front disc brake lower pump 210 and the rear disc brake lower pump 230 through the ABS control valve 100 for simultaneously braking the front wheel 31 and the rear wheel 33.

[0041] Based on the above settings, the anti-lock braking system 10 of the present application can achieve combined braking and cross braking control of the front wheel 31 and the rear wheel 33 through the ABS control valve 100. That is to say, whether in the front braking controlled by the front disc brake upper pump 310 or in the rear braking controlled by the rear disc brake upper pump 330, the ABS control valve 100 can reasonably distribute the braking force to the front and rear wheels, reduce the change of the vehicle body center of gravity, and improve the braking efficiency and braking stability. It can be understood that the above front braking and rear braking are independent of each other and can operate simultaneously or separately.

[0042] Specifically, when the anti-lock braking system 10 performs front braking, the front disc brake master cylinder 310 operates. The hydraulic oil is diverted by the ABS control valve 100 to the front disc brake slave cylinder 210 and the rear disc brake slave cylinder 230, and accordingly transmits the braking force to the front disc brake slave cylinder 210 and the rear disc brake slave cylinder 230, thereby achieving the beneficial effects of simultaneous braking of the front and rear wheels, improving braking efficiency and braking stability, and enhancing driving safety. Additionally, it should be noted that the situation of the anti-lock braking system 10 performing rear braking is similar to the above, and will not be elaborated here.

[0043] It should be emphasized that the ABS control valve 100 here is the core component for realizing the linkage control of the front and rear wheels. It will determine whether to adjust the pressures of the front disc brake slave cylinder 210 and the rear disc brake slave cylinder 230 according to the detected wheel speed information. When it is detected that a certain wheel is about to or has already locked, the ABS control valve 100 will reduce the braking pressure of the corresponding wheel, allowing the wheel to continue rolling and avoiding skidding.

[0044] Please refer to Figure 2 , in front braking, the anti-lock braking system 10 further includes a first inlet pipe 410, a first outlet pipe 430, and a second outlet pipe 450. Among them, the first inlet pipe 410 connects the front disc brake master cylinder 310 and the ABS control valve 100, and is used to transmit the hydraulic power from the front disc brake master cylinder 310. The first outlet pipe 430 connects the ABS control valve 100 and the front disc brake slave cylinder 210 to ensure that the front wheel 31 receives appropriate braking pressure; the second outlet pipe 450 connects the ABS control valve 100 and the rear disc brake slave cylinder 230 to ensure that the rear wheel 33 receives appropriate braking pressure.

[0045] That is to say, in this application, the first inlet pipe 410 is responsible for transmitting the input braking pressure, while the first outlet pipe 430 and the second outlet pipe 450 are responsible for adjusting the output braking force. Each of the above pipes has a clear function, which is convenient for system design and later maintenance. Specifically, if any of the above pipes fails, the independent pipe can be diagnosed and repaired to avoid affecting the normal operation of other parts.

[0046] Similarly to the above, in rear braking, the anti-lock braking system 10 further includes a second inlet pipe 510, a third outlet pipe 530, and a fourth outlet pipe 550. Among them, the second inlet pipe 510 connects the rear disc brake master cylinder 330 and the ABS control valve 100, and is used to transmit the hydraulic power from the rear disc brake master cylinder 330. The third outlet pipe 530 connects the ABS control valve 100 and the front disc brake slave cylinder 210 to ensure that the front wheel 31 receives appropriate braking pressure; the fourth outlet pipe 550 connects the ABS control valve 100 and the rear disc brake slave cylinder 230 to ensure that the rear wheel 33 receives appropriate braking pressure. It can be understood that the working principles and beneficial effects of the above pipes are similar to those of the pipes in front braking, and will not be elaborated here.

[0047] Please refer to again Figure 2 Figure 2 , in some embodiments, to facilitate the user to flexibly select the front drive or rear drive mode in different situations, the anti-lock braking system 10 further includes a front disc brake drive member 610 and a rear disc brake drive member 630. Among them, the front disc brake drive member 610 is connected to the front disc brake master cylinder 310 and is used to make the front disc brake master cylinder 310 act under an external force; the rear disc brake drive member 630 is connected to the rear disc brake master cylinder 330 and is used to make the rear disc brake master cylinder 330 act under an external force.

[0048] Further, to ensure the convenience of user operation, the front disc brake drive member 610 is a front disc brake handle or a front disc brake foot pedal, and the rear disc brake drive member 630 is a rear disc brake handle or a rear disc brake foot pedal. Optionally, the front disc brake drive member 610 can be set as a front disc brake handle located on the left side of the handlebar, so as to facilitate the user to perform braking operations with the left and right hands during riding; and the rear disc brake drive member 630 can be set as a rear disc brake foot pedal located on the right side of the vehicle, so as to facilitate the user to perform braking operations with the right foot.

[0049] Please refer to again Figure 2 and Figure 3 Figure 2 , to enable the front disc brake slave cylinder 210 to quickly respond to front braking and rear braking respectively, the front disc brake slave cylinder 210 includes a first oil cylinder, a second oil cylinder, a first brake piston 211 and a second brake piston 213. Among them, the first oil cylinder is communicated with the front disc brake master cylinder 310, and the first brake piston 211 cooperates with the first oil cylinder and is used to brake the front wheel 31 under the action of the front disc brake master cylinder 310; the second oil cylinder is communicated with the rear disc brake master cylinder 330, and the second brake piston 213 cooperates with the second oil cylinder and is used to brake the rear wheel 33 under the action of the rear disc brake master cylinder 330.

[0050] That is to say, the first oil cylinder is communicated with the front disc brake master cylinder 310 and is used to brake the front wheel 31 in the case of front braking; while the second oil cylinder is communicated with the rear disc brake master cylinder 330 and is used to brake the front wheel 31 in the case of rear braking. Based on the above settings, the front disc brake slave cylinder 210 forms an independent dual braking design. On the one hand, in an emergency, the above design can provide multi-level braking, facilitating the driver to flexibly adjust the braking force according to different driving needs; on the other hand, the above design can achieve multi-level protection, that is, when any one of the front braking or rear braking fails, it ensures that the other can still work normally, improving driving safety.

[0051] Similarly, to enable the rear disc brake lower pump 230 to quickly respond to front braking and rear braking respectively, the rear disc brake lower pump 230 includes a third oil cylinder, a fourth oil cylinder, a third brake piston 231, and a fourth brake piston 233. Among them, the third oil cylinder is communicated with the front disc brake upper pump 310, the third brake piston 231 cooperates with the third oil cylinder, and is used to brake the rear wheel 33 under the action of the front disc brake upper pump 310; the fourth oil cylinder is communicated with the rear disc brake upper pump 330, the fourth brake piston 233 cooperates with the fourth oil cylinder, and is used to brake the rear wheel 33 under the action of the rear disc brake upper pump 330.

[0052] It should be noted that based on the above settings, the rear disc brake lower pump 230 also forms an independent dual braking design, and its working principle and beneficial effects are similar to those of the front disc brake lower pump 210, which will not be elaborated in this application. In addition, it should also be noted that in the front disc brake lower pump 210, the number of the first brake pistons 211 is two, and the number of the second brake pistons 213 is one, so as to participate in front braking and rear braking to different degrees, facilitating the user to adjust. Correspondingly, in the rear disc brake lower pump 230, the number of the third brake pistons 231 is one, and the number of the fourth brake pistons 233 is two.

[0053] To facilitate the fixing of the position of the front disc brake lower pump 210, the antilock braking system 10 further includes a first bracket 710. The first bracket 710 is connected to the front disc brake lower pump 210 and is used to be connected to the vehicle body. Optionally, the first bracket 710 is connected to the bottom cylinder 50 of the front shock absorber on the motorcycle 1 to effectively reduce the vibration generated during braking and improve the stability and reliability of the system. Correspondingly, to facilitate the fixing of the position of the rear disc brake lower pump 230, the antilock braking system 10 further includes a second bracket 730. The second bracket 730 is connected to the rear disc brake lower pump 230 and is used to be connected to the vehicle body. Optionally, the second bracket 730 is connected between the rear wheel and the rear swingarm.

[0054] Taking this embodiment as an example, the present application provides an antilock braking system 10, and its working principle and working process are as follows:

[0055] When the antilock braking system 10 performs front braking, the front disc brake upper pump 310 acts, and the hydraulic oil is shunted to the front disc brake lower pump 210 and the rear disc brake lower pump 230 through the ABS control valve 100, and correspondingly transmits the braking force to the front disc brake lower pump 210 and the rear disc brake lower pump 230, so that the front and rear wheels of the vehicle are braked simultaneously.

[0056] When the antilock braking system 10 performs rear braking, the rear disc brake upper pump 330 acts, and the hydraulic oil is shunted to the front disc brake lower pump 210 and the rear disc brake lower pump 230 through the ABS control valve 100, and correspondingly transmits the braking force to the front disc brake lower pump 210 and the rear disc brake lower pump 230, so that the front and rear wheels of the vehicle are braked simultaneously.

[0057] In summary, the present application provides an anti-lock braking system 10 and a motorcycle 1. The anti-lock braking system 10 includes an ABS control valve 100, a front disc brake slave cylinder 210 for braking the front wheel 31, a rear disc brake slave cylinder 230 for braking the rear wheel 33, a front disc brake master cylinder 310, and a rear disc brake master cylinder 330. Among them, the front disc brake master cylinder 310 is connected to the front disc brake slave cylinder 210 and the rear disc brake slave cylinder 230 through the ABS control valve 100 for braking the front wheel 31 and the rear wheel 33 simultaneously; the rear disc brake master cylinder 330 is connected to the front disc brake slave cylinder 210 and the rear disc brake slave cylinder 230 through the ABS control valve 100 for braking the front wheel 31 and the rear wheel 33 simultaneously.

[0058] It should be noted that, without conflict, the features in the embodiments of the present application can be combined with each other.

[0059] The above are only the preferred embodiments of the present application and are not used to limit the present application.
