The invention discloses a limited slip differential and a vehicle, and the limited slip differential comprises a first power assembly which comprises a first output shaft and a first connecting piece; the second power assembly comprises a second output shaft and a second connecting piece; the mounting shell comprises a driven shaft connected to the inner wall of the mounting shell, a slip limiting assembly and a third connecting piece, the slip limiting assembly and the third connecting piece are fixedly connected to the driven shaft, and the third connecting piece is engaged with the first connecting piece and the second connecting piece; the sliding limiting assembly further comprises a friction block, and the friction block abuts against the inner wall of the installation shell. According to the limited slip differential and the vehicle provided by the embodiment of the invention, when the third connecting piece and the driven shaft start to rotate, the friction block also starts to rotate around the driven shaft, so that the friction force between the friction block and the inner wall of the mounting shell is increased, the rigid connection between the first output shaft and the second output shaft is enhanced, and the transferred output power is increased; and the output power transmission proportion between the first output shaft and the second output shaft is changed along with the slipping degree.

This invention relates to the field of grinding equipment and provides a surface grinding device and method for curved LCD screens based on a laser pointer. The device includes a fixedly mounted lifting frame and a platform. A transport guide rail is located at the bottom of the lifting frame, and a traction handle is located at the top of the platform. A grinding mechanism is located at the bottom of the platform. Each of the four corners of the platform has a branch tube. A display screen workpiece is placed at the top of the frame and the branch tubes, and edge protection components are provided at the ends of the branch tubes. In use, the display screen workpiece is placed on the frame and the branch tubes. A stepper motor drives a steering gear set via its output shaft. The steering gear set drives a drive bevel gear through a telescopic sleeve. The drive bevel gear simultaneously drives both the forward and reverse bevel gears. During the grinding process, the grinding ring and grinding disc apply opposite frictional forces to the display screen workpiece. These two frictional forces cancel each other out, thus achieving precise grinding.

The balance maintaining device is used for the two-wheeled vehicle, the two-wheeled vehicle comprises a front fork and a vehicle frame, the front fork is rotatably connected with the vehicle frame, the balance maintaining device comprises a first driving part, an adjusting assembly and a sensor, the first driving part is suitable for being fixed to the vehicle frame, and the adjusting assembly is in transmission connection with the first driving part; the sensor is electrically connected with the first driving part, the sensor is suitable for detecting the inclination angle of the frame, the first driving part drives the adjusting assembly to rotate around the axis extending in the length direction of the frame according to the inclination angle of the frame, and the adjusting assembly rotates to the inclined side of the frame. The adjusting assembly can rotate towards the inclined side of the two-wheeled vehicle to lower the gravity center of the two-wheeled vehicle, the centripetal force of the two-wheeled vehicle is improved, and the situation that the two-wheeled vehicle topples over to harm the safety of a driver and passengers is prevented.

The application discloses a simple structure's annular suspension electromagnetic propulsion system and method. The system comprises a centripetal-suspension system and an acceleration system. The centripetal-suspension system comprises a centripetal-suspension field coil fixed on the ground and a rotatable load end centripetal-suspension unit. The acceleration system comprises an acceleration coil fixed on the ground and a force receiving unit. The acceleration coil and the force receiving unit are located on the axis of the load end centripetal-suspension unit, and the load end centripetal-suspension unit is connected with the force receiving unit through a connecting unit. The centripetal-suspension field coil is used for generating a centripetal-suspension magnetic field in an annular area with a certain height and width. The centripetal-suspension field is used for ensuring that the suspension force is enhanced along the vertical direction downward and is reduced upward. The current in the load end centripetal-suspension unit and the centripetal field generate a centripetal force pointing to the center of the annular area, which offsets the centrifugal force generated by the rotation of the load and accelerates together with the load. The application greatly improves the acceleration capacity of the system.

The invention belongs to the technical field of additive preparation, and particularly relates to an acid copper plating additive preparation method and device.The preparation device comprises a base frame, a stirring barrel and a cover are arranged at the upper end of the base frame, by arranging a containing frame and a barrier plate, when an acid copper plating additive is prepared, an abutting block is started, and the stirring barrel and the cover are sealed; when the steel ball falls into the first storage cavity, the abutting block moves downwards, the abutting block drives the pushing block to move downwards together, the pushing block makes contact with the steel ball at the topmost end and drives the steel ball to move in the sliding groove, the steel ball falls into a falling groove close to one end of the first storage cavity and makes contact with a falling platform, and the steel ball falls into the falling platform through pressure caused by the steel ball. When the mixing drum is in use, a sealing door at the lower end can be opened, so that a grain refiner is automatically poured out, and when a brightener, a leveling agent and a surfactant need to be added again, raw materials in corresponding cavities can be sequentially added into the mixing drum only by starting an abutting block.

The utility model provides a lithium ore flotation device, relates to the technical field of flotation, and solves the problem that when the flotation device floats ore pulp, bubbles are difficult to sufficiently collide and attach to mineral particles due to sedimentation of the ore pulp in injected airflow. An inflation tube is arranged at the bottom of the body, a spiral tube is arranged at one end of the inflation tube, an exhaust hole is formed in the side wall of the spiral tube, a contraction groove is formed in one side of the middle of the exhaust hole, a protection assembly is arranged in the middle of the contraction groove, and the protection assembly slides along the contraction groove. By means of the spiral pipe arranged in the device, certain centripetal force can be increased to discharged airflow when the airflow is discharged to generate bubbles, and therefore certain stirring can be generated to flotation liquid and ore pulp when the airflow is discharged.
