Detailed Description
The intelligent brake master cylinder for the two-wheel vehicle can realize intelligent adjustment of the pressure of the brake master cylinder, solve the problem of emergency braking and anti-lock of the two-wheel vehicle, and increase the driving safety coefficient; and can be used for the deceleration and braking of other movement mechanisms. The present utility model will be further described with reference to the accompanying drawings.
The intelligent brake master cylinder mainly comprises an oilcan 2, a cylinder body 3, a first piston 4, a clamp spring 5, a transmission mechanism 6, a controller 7, a motor 8, a position detection sensor 9, a caliper 10, a wheel speed sensor 11 and a second piston 13, and the working principle is mainly as follows: the brake handle 1 is connected with the second piston 13 through a hinge, the brake handle 1 is pinched by hand, the second piston 13 is pushed to move rightwards, the oil pressure in the hydraulic cylinder is increased and is simultaneously transmitted to the brake disc caliper assembly, the caliper 10 clamps the brake disc 12, the wheel speed sensor 11 monitors that the wheel speed is close to locking, a signal is fed back to the controller 7, the controller 7 controls the motor 8 to rotate to generate torque, the transmission mechanism 6 changes the rotation movement into linear movement to push the first piston 4 to move rightwards, the volume in the main cylinder cavity is increased, the caliper pressure is reduced, the wheels continue to rotate, the wheel speed sensor 11 monitors that the information is continuously fed back to the controller 7, the controller 7 controls the motor 8 to rotate reversely to generate torque, the transmission mechanism 6 changes the rotation movement into linear movement to push the first piston 4 to move leftwards, the volume in the main cylinder cavity is reduced to compress the hydraulic oil, the caliper pressure is increased, and the wheels continue to slow down. And finally, stopping the wheels. After the wheels are stopped, the position of the first piston 4 is controlled by the controller 7 to rotate back to the original position for standby according to feedback information of the position detection sensor 9. The position detection sensor 9 may be selected and removed according to the actual application.
According to actual working conditions, the intelligent master cylinder for the two-wheel vehicle works in three conditions:
Normal deceleration of vehicle
Under the working condition, a driver can completely drive the vehicle, the second piston 13 can be pushed by the brake handle 1 to decelerate, and the oil pressure required for deceleration is mainly generated by the fact that the second piston 13 is pushed by the brake handle 1 to push the brake disc caliper assembly to brake. The motor 8 will not be in operation at this time.
Emergency brake for vehicle
Under the working condition, when a driver encounters an emergency, the brake handle 1 is pinched under full force, the oil pressure generated by the second piston 13 can enable the brake disc caliper assembly to brake rapidly, and when the wheel speed sensor 11 senses that the wheel is about to be locked, information is fed back to the controller 7, and the controller 7 rapidly controls the motor 8 to decompress. Meanwhile, as the pressure of the calipers is reduced, the wheel speed is recovered to rotate due to inertia, the wheel speed sensor 11 feeds back a wheel speed signal to the controller 7, and the controller 7 starts to control the motor 8 to boost, so that the vehicle is reciprocated until the vehicle is stopped stably;
Braking standby
After braking is completed, the position detection sensor 9 feeds back a position signal of the first piston 4 to the controller 7, and the controller 7 controls the motor 8 to drive the piston to return to the original position through the transmission mechanism 6 so as to carry out pressure regulation and standby for subsequent braking.
