Abstract: A braking mechanism, a mechanical brake, an electronic mechanical braking system, and a vehicle. The braking mechanism includes: a fixed caliper; two braking units, where the two braking units are arranged in a first direction, a braking gap used by a part of a brake disc for extending is formed between the two braking units; two crankshaft units that are in a one-to-one correspondence with the two braking units, where in each group of the braking unit and the crankshaft unit that correspond to each other, the crankshaft unit is located on a side that is of the braking unit and that is away from the braking gap, the crankshaft unit is rotatably installed on the fixed caliper around a first axis, and the first axis is perpendicular to the first direction; and a drive unit. The braking mechanism can avoid a reliability risk of the system.

Abstract: A parking mechanism that includes a wheel disc, a wedge disc, and a drive assembly. An axis of the wheel disc and an axis of the wedge disc both are aligned with an axis of a motor shaft. A wedge groove with an opening facing the wheel disc is formed on a surface of the wedge disc facing the wheel disc, and a movable part in contact with the wheel disc is disposed in the wedge groove. In a direction from a bottom of the wedge groove to the wheel disc, a groove depth at a first end of the wedge groove is greater than a size of the movable part, and a groove depth at a second end of the wedge groove is less than the size of the movable part. The parking mechanism can provide stepless variable parking force.

Abstract: This application provides a braking system, a control apparatus, and an electric vehicle. The braking system includes a controller and four actuators. Each actuator includes a brake disc. The braking system is configured to adjust, based on temperatures of four brake discs, braking force output by the four actuators. The controller is configured to control an actuator corresponding to a brake disc with a too high temperature to reduce braking force output, or is configured to control an actuator corresponding to a brake disc with a too low temperature to increase braking force output.

Abstract: An electronic mechanical brake system and a vehicle. The electronic mechanical brake system includes a brake pedal, an electronic brake mechanism, a mechanical brake mechanism, a brake, and a switch mechanism with a first state and a second state. The electronic brake mechanism includes a controller and an electronic signal sensor. The controller, the electronic signal sensor, and the brake are electrically connected. When the switch mechanism is in the first state, the electronic signal sensor is configured to receive a braking signal of the brake pedal and transmit the braking signal to the controller. The controller controls the brake to brake based on the braking signal. The electronic mechanical brake system can improve driving safety. In addition, reliability of the mechanical brake system is high, and costs are low.
