The invention discloses a wheel set assembly for a meter gauge axle disc braking bullet train bogie. The wheel set assembly is mainly composed of wheels, an axle, an axle box assembly, a braking disc and a driving device. The axle box assembly is of a penetrated type structure, and the axle penetrates through a front cover and a rear cover of an axle box. The front cover of the axle box is matched with a partition cylinder through a labyrinth seal structure, and the rear cover of the axle box is matched with a dustproof check ring through a labyrinth seal structure. The front cover of the axle box and the axle are sealed in a contact mode, and the rear cover of the axle box and the axle box are sealed in a contact mode. The axle extends to penetrate through the axle box assembly, and the braking disc is installed on the part, penetrating out of the outer side of the axle box, of the axle, installed in a key or spline structure matching mode and pressed through an axle end bolt and a gland ...

The invention discloses a meter gauge axle disc braking bullet train bogie. A penetrating type axle box assembly is adopted, and an axle extends outside the axle box assembly. A braking disc is installed on the part, stretching out of the axle box, of the axle. Framework side beams are of C-shaped structures, and the two ends of each side beam are each provided with a section of suspension arm type structure which extends outside the corresponding side beam in a suspending mode and used for lifting a four-point suspension type braking unit. A guide pillar type structure is adopted in a suspension device. The meter gauge axle disc braking bullet train bogie completes the installation of an axle disc type basic braking device on the meter gauge bogie, the braking thermal capacity limiting value is greatly increased exactly due to the application of the axle disc type basic braking device, and therefore the highest operation speed of trains is increased. The structure of the bogie is more ...

The invention relates to a meter-gauge quasi-high-speed axle disc brake electric multiple unit bogie. The meter-gauge quasi-high-speed axle disc brake electric multiple unit bogie is characterized by adopting through axle box assemblies and lengthening axles out of the axle box assemblies, and brake discs are mounted on the axles extending out of the axle box assemblies; a split type structure is adopted by frame end beams, two cantilever type end beams are respectively arranged on both ends of each side beam, and cantilever out from the side beam, and the cantilever type end beams are used for hoisting compact brake units; a tumbler type positioning and helical steel spring bearing structure is adopted by a primary suspension. Because the braking heat capacity limit is greatly increased by the application of the axle disc type foundation brake riggings, the highest running speed of a car is increased; since the brake discs are mounted outside the axle boxes, the problem that a brake disc-mounting ...

The invention relates to a test method and device of projection equipment, computer equipment and a storage medium. The method comprises the following steps: acquiring a current switching signal corresponding to a current on-off state; the current switching signal is determined based on an optical signal detected at the projection position when the projection equipment is in the current on-off state; the current on-off state is opposite to the previous on-off state represented by the previous switching signal; the previous on-off state is the on-off state of the projection equipment before switching to the current on-off state; and under the condition that the time interval between the current switching signal and the previous switching signal accords with a preset time interval, controlling the projection equipment to switch the on-off state, and returning to the step of acquiring the current switching signal corresponding to the current on-off state to continue to execute until the number ...
