The utility model provides a tricycle brake disc relates to brake disc technical field, including the support shell, the top fixedly connected with two support blocks of support shell, the top of support block is established with the axle hole, the bottom fixedly penetrates to the bottom of support shell of axle hole, the top of support shell is provided with the rotating lever, the top fixedly connected with the rotating plate of rotating lever, two the top of rotating plate is provided with the support plate, the inner wall rotationally connected with the axle of axle hole. The utility model, through fixedly connecting two support blocks in the top of support shell, and establishing the axle hole in the top of support block, makes rotating lever can drive rotating plate to carry out effective rotation control, the rotary connection of rotating plate and support plate makes whole brake system can realize more even brake force distribution, especially, in the design, the inner wall fixedly connected baffle of brake shell's one side, and fixedly connected through the spring, makes baffle can rebound quickly in the brake process, ensures that the contact of brake shoe and brake disc is more even.

The application discloses a trailer brake control method and device based on a semitrailer and the semitrailer. The method comprises the following steps: acquiring type information, running state information and posture information of the semitrailer, wherein the running state information at least comprises steering angle information, vehicle speed information and retarder torque information; judging whether the semitrailer has a folding dynamic of the trailer based on the type information, the running state information and the posture information; and generating a brake control strategy for controlling the trailer valve to brake the trailer of the semitrailer in the case that it is determined that the semitrailer has the folding dynamic of the trailer. The application solves the technical problem of folding of the trailer and the main vehicle caused by the trailer pushing the main vehicle.

The invention relates to the technical field of vehicle safety, in particular to an emergency braking system and a vehicle, the emergency braking system comprises a driving mechanism and a wear-resistant pressure-bearing assembly, and the driving mechanism is arranged on a carrier; the wear-resisting pressure-bearing assembly is connected to the output end of the driving mechanism and provided with a contact face used for abutting against the ground. Wherein the driving mechanism is used for driving the wear-resistant pressure-bearing assembly to be switched between a working position and a storage position; when the wear-resisting pressure-bearing assembly is located at the working position, the contact face abuts against the ground, and braking force is generated on the carrier through friction force. According to the emergency braking system, effective emergency braking can be conducted on the vehicle after vehicle braking fails, and safety is improved.
