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.

Abstract: This application relates to a brake apparatus. The brake apparatus is connected to a rotating part. The brake apparatus includes a housing connected to the rotating part, a brake part, a transmission part, a drive part, a gain mechanism, and a compensation mechanism. The drive part drives, by using the transmission part, the brake part to move along a direction close to or away from the rotating part for braking and braking release. A moving member of the compensation mechanism is connected to the gain mechanism, and a transmission member of the compensation mechanism is connected to the drive part, to drive the gain mechanism to move along a direction close to the brake part. Such a design improves resetting efficiency of the brake part, and compensation is performed by using a mechanical structure, which helps simplify a structure of the brake apparatus and better meets an actual use requirement.

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: A braking mode switching apparatus includes a braking mode selection component, a transmission member, a stopper, a driver, and a motion control component. The braking mode selection component can move between a first position corresponding to a first braking mode and a second position corresponding to a second braking mode. The transmission member has a first transmission portion and a second transmission portion. The stopper includes a first stopper portion and a second stopper portion. The motion control component is configured to abut against the first stopper portion in response to a case in which the driver is powered on, where the braking mode selection component is located in the first position; and abut against the second stopper portion in response to a case in which the driver is not powered on, where the braking mode selection component is located in the second position.
