The invention discloses an air stand-by brake system and brake method. The air stand-by brake system comprises a brake controller, an equalizing reservoir, a relay valve, an input valve and a throttle valve; the air stand-by brake system is connected with an original train pipe of a locomotive through the input valve, and connected with an original main blast line of the locomotive through the throttle valve; if a main brake control system is power-off, the input valve is used for being opened to a switch-on position, so that an air channel is communicated; the brake controller is used for controlling the pressurization and depressurization of the equalizing reservoir; the equalizing reservoir is used for taking the pressure of the equalizing reservoir as the pilot pressure of the relay valve; and the relay valve is used for controlling the pressure change of the train pipe according to the pressure change of the equalizing reservoir, wherein the pressure of the equalizing reservoir and the pressure of the train pipe are in a synchronous state. According to the embodiment of the invention, the brake function of the locomotive can be ensured, so that the locomotive can continue to run and maintain to a locomotive depot, and then is maintained, in such a way, the locomotive does not stop on a trunk railway for a long tine, thereby reducing the effect on the order of a railway.

The invention relates to a household cooking appliance which includes a receptacle (2). The inside of the receptacle (2) is provided with a cutting tool (4) which is driven by a motor (15). The receptacle (2) is closed by a removable cover (3) comprising a bracket (34) acting on a safety part (7) when the bracket (34) of the cover (3) is turned toward an operating position. The safety part (7) moves between an idle position and an activated position. The safety part (7) is returned to the idle position via a return mechanism (72). When the bracket (34) is on the operating position (34), the safety part (7) is brought t to the activated position. The safety part (7) comprises a metal braking shoe (76) rubbing against a transmission belt (16) rotatingly integrated to the cutting tool (4) when the safety part is in a rest position. The shoe (76) is arranged apart from the belt (16) when the safety part is in an activated position.

A pump-type hydraulic coupler belongs to a vehicle coupler, in which a pinion is rotating connected in the casing. The pinion inside engaged with a big gear ring. There is a crescent spacer between the pinion and the big gear ring. The back cover of the casing is connected with the casing. One end of connection of the pinion and the casing is connected with a one-way clutch.

A brake pedal simulator, a vehicle braking system and a vehicle are provided. The brake pedal simulator includes a brake pedal, a booster motor, an assembly part for fitting to a vehicle body, a firstelastic member and a second elastic member axially disposed on one side of the fitting portion and at least partially overlapping with each other in the axial direction, and a thrust structure hingedto the brake pedal and cooperating with one end of the overlapping portion of the first elastic member and the second elastic member to be capable of driving the first elastic member and the second elastic member while telescoping in the axial direction, The first elastic member and the second elastic member cooperate to provide a pedal preset force to the brake pedal, and the output shaft of thebooster motor cooperates with one end of the overlapping portion of the first elastic member and the second elastic member through a rack-and-pinion mechanism so as to be able to provide a boosting force to the thrust structure. This provides a reliable braking feel of the brake pedal and simulates an accurate brake pedal force, and has the effects of good operation stability and corresponding quick brake pedal.

The invention discloses wind driven generator braking equipment. The equipment comprises a drum brake and a drum brake cavity formed in the drum brake. A body is arranged in the drum brake cavity, andinternally provided with a braking trigger cavity. A center threaded rod extending front and back is arranged in the braking trigger cavity and connected with a push block in a screw thread fit mode.The push block is connected with a lifting block in an abutting mode. The lifting block is connected with a lifting rod in a stationary fit mode. A gear and rack engaging cavity is formed above the braking trigger cavity. The invention aims at designing a device capable of performing braking on a wind driven generator when the rotating speed of the wind driven generator reaches a certain value soas to reduce the speed of the wind driven generator device.

A brake pedal simulator, a vehicle braking system and a vehicle are provided. The brake pedal simulator includes a brake pedal, a booster motor, an assembly portion, a first elastic member and a second elastic member disposed on one side of the assembly portion in the axial direction and partially overlapping with each other in the axial direction, and a thrust structure hinged to the brake pedaland cooperating with the first elastic member to sequentially drive the first elastic member and the second elastic member to telescopically retract in the axial direction. The elastic resilient member provides a pedal preset force to the brake pedal, The output shaft of the booster motor is cooperated with the first elastic member through a rack and pinion mechanism so as to be able to provide assistance to the thrust structure, the first elastic member is compressed through the thrust mechanism in a first working state, and the first elastic member and the second elastic member are compressed synchronously through the cooperation of the thrust structure and the booster motor in a second working state. This provides a reliable braking feel of the brake pedal and simulates an accurate brake pedal force, and has the effects of good operation stability and corresponding quick brake pedal.
