Background
The front and rear linkage Braking System (CBS) is used for Braking the rider, and can simultaneously brake the front and rear wheels by only Braking at either the left side or the right side, so that the skidding caused by single-wheel Braking or the overturning caused by single-wheel Braking can be reduced. In other words, the CBS can decelerate the front and rear wheels simultaneously, maintain the stability of the fuselage, and reduce the slip probability of the rear wheels. However, the most problematic issue of the conventional linked braking is that the front and rear brakes are mechanical, and the distribution ratio of the front and rear brakes is fixed and cannot be changed, so that the braking habit of all users cannot be met.

For a fuller understanding of the present invention, reference should be made to the following detailed description taken in conjunction with the accompanying drawings. The purpose, characteristics and function of the present invention will be understood by those skilled in the art from the disclosure of the present specification. It is to be understood that the invention may be practiced or applied to other embodiments, and that various changes, modifications, and alterations may be made in the details of this description without departing from the spirit thereof. The drawings attached to the present invention are for simplicity and illustrative purposes only, and are not drawn to scale. The following embodiments will further explain the related art of the present invention in detail, but the disclosure is not intended to limit the claims of the present invention. The description is as follows:
referring to fig. 1, a variable interlock brake system 100 for an electric motorcycle according to an embodiment of the present invention includes: a power wheel motor 1, a non-power wheel brake 2, a brake control distributor 3 and a non-power wheel brake trigger 4.
The power wheel motor 1 is connected to the power wheel (i.e. the power wheel motor 1 directly power drives the power wheel). The power wheel motor 1 provides power for the motor to provide power for the power wheel when moving, and provides braking resistance for the power wheel when braking. In this embodiment, the preset powered wheel is a rear wheel of the electric locomotive, and the non-powered wheel is a front wheel of the electric locomotive, but the invention is not limited thereto.
The non-powered wheel brake 2 is installed on the non-powered wheel to provide braking resistance for the non-powered wheel. The non-powered wheel brakes 2 are, for example, brake calipers, but the invention is not limited thereto.
The brake control distributor 3 is connected with the power wheel motor 1 and the non-power wheel brake 2 by signals, and the brake control distributor 3 can be provided with a central processing unit and a memory for processing and transmitting signals.
The non-powered wheel brake trigger 4 is connected with the brake control distributor 3 by signals. Non-powered wheel brake trigger 4 is, for example, a brake lever, a brake pedal, or any type of brake switch, and the invention is not limited thereto.
When the non-powered wheel brake trigger 4 is triggered to generate a brake signal Sb to the brake control distributor 3, the brake control distributor 3 will output the ratio and the values of the braking resistance of the powered wheels and the braking resistance of the non-powered wheels, and control the powered wheel motor 1 and the non-powered wheel brake 2 to brake according to the ratio output by the brake control distributor 3.
The brake control distributor 3 can output the above-mentioned ratio and value according to various conditions, and the ratio and value can be changed in real time with time and conditions.
As shown in FIG. 1, in one embodiment, the variable interlock braking system 100 of the electric motorcycle further comprises a vehicle speed sensor 5 connected to the brake control distributor 3. The brake control distributor 3 outputs the ratio of the braking resistance of the power wheel and the braking resistance of the non-power wheel according to a real-time vehicle speed signal Sv corresponding to the real-time vehicle speed measured by the vehicle speed sensor 5. In the present embodiment, the real-time vehicle speed may be proportional to the ratio, and the ratio may continuously increase with the increase of the vehicle speed (i.e. the faster the vehicle speed, the higher the proportion of the braking resistance of the power wheels from the power wheel motor 1), but the invention is not limited thereto. In another example, the increase may be in stages.
In one embodiment, as shown in FIG. 1, brake signal Sb may be a signal having a magnitude, and the magnitude of brake signal Sb may be proportional to the ratio, with the ratio of powered wheel braking resistance to non-powered wheel braking resistance being higher for larger values of brake signal Sb (the larger the magnitude of brake signal Sb, the higher the proportion of powered wheel braking resistance from powered wheel motor 1), although the invention is not limited thereto. In another example, the increase may be in stages. In a specific embodiment, as shown in fig. 1, the non-powered wheel brake trigger 4 may include a brake pull rod 41, a pressing stroke of the brake pull rod 41 may be proportional to a value of the brake signal Sb, and when the pressing stroke of the brake pull rod 41 is larger, the non-powered wheel brake trigger 4 generates the brake signal Sb with a larger value. However, the present invention is not limited thereto.
As shown in FIG. 1, in one embodiment, the variable interlock braking system 100 of the electric motorcycle further comprises an acceleration sensor 6 in signal communication with the brake control distributor 3. The brake control distributor 3 outputs the ratio of the braking resistance of the powered wheels to the braking resistance of the non-powered wheels according to a real-time acceleration signal Sa (acceleration which can be positive or negative) corresponding to the real-time acceleration value of the vehicle body measured by the acceleration sensor 6. In the present embodiment, the absolute value of the real-time acceleration value may be proportional to the ratio, and the ratio may continuously increase as the absolute value of the acceleration value increases (i.e., the more positive or the more negative the acceleration value, the higher the proportion of the power wheel braking resistance from the power wheel motor 1 is), although the present invention is not limited thereto. In another example, the increase may be in stages.
As shown in FIG. 1, in one embodiment, the variable interlock brake system 100 of the electric motorcycle further comprises a power mode output 7, which is in signal connection with the brake control distributor 3. The brake control distributor 3 outputs the ratio of the braking resistance of the powered wheels to the braking resistance of the non-powered wheels according to the power mode signal Sm corresponding to the power mode output by the power mode output device 7. For example, the power consumption of the power mode can be proportional to the ratio, and the power mode output device 7 can output three power modes in this embodiment: economy mode, comfort mode, and sport mode. The power wheel motor 1 performs corresponding power output (e.g., how many revolutions and how intermittently) depending on the power mode output by the power mode output 7. When the non-powered wheel brake trigger 4 generates the brake signal Sb, the brake control distributor 3 outputs the ratio of the powered wheel brake resistance and the non-powered wheel brake resistance according to the current power mode (economy mode, comfort mode, or sport mode). In the present embodiment, a power mode with a lower power consumption corresponds to a lower ratio (i.e., a lower proportion of the power wheel braking resistance from power wheel motor 1). However, the present invention is not limited thereto.
As shown in FIG. 1, in one embodiment, the variable interlock braking system 100 of the electric motorcycle further comprises a power wheel load sensor 8 in signal communication with the brake control distributor 3. The brake control distributor 3 determines the ratio of the braking resistance of the powered wheels and the braking resistance of the non-powered wheels according to a powered wheel load signal Sl corresponding to the powered wheel load sensed by the powered wheel load sensor 8. In the present embodiment, the power wheel load may be proportional to the ratio, and the ratio may be continuously increased as the power wheel load increases (i.e., the higher the power wheel load, the higher the proportion of the power wheel braking resistance from the power wheel motor 1), but the present invention is not limited thereto. In another example, the increase may be in stages.
As shown in FIG. 1, in one embodiment, the variable interlock braking system 100 of the electric motorcycle further includes a body tilt sensor 9, which is in signal communication with the brake control distributor 3. The vehicle body inclination angle sensor 9 senses an inclination angle of the vehicle body. The brake control distributor 3 determines the ratio of the braking resistance of the powered wheels and the braking resistance of the non-powered wheels according to the vehicle inclination angle signal Si corresponding to the vehicle inclination angle sensed by the vehicle inclination angle sensor 9. In the present embodiment, the vehicle body inclination angle may be inversely proportional to the ratio that decreases continuously as the vehicle body inclination angle increases (i.e., the larger the vehicle body inclination angle, the lower the proportion of the power wheel braking resistance from the power wheel motor 1), although the present invention is not limited thereto. In another example, the reduction may be in stages.
By the variable linkage braking system 100 of the electric locomotive, different braking proportions can be distributed according to various real-time vehicle conditions, so that the power wheel motor generates different and continuously-changed resistances, and the purpose of linkage braking of the non-power wheels and the power wheels is achieved. In addition, the variable linkage braking system of the electric locomotive can recover partial kinetic energy to be converted into electric energy, and can achieve more excellent braking performance and stability by virtue of linkage braking in different proportions.
