2results about How to "Control driving speed" patented technology

The application relates to the electrical field and discloses an industrial vehicle lane driving safety control system and a control method thereof. The system comprises: a plurality of magnetic switch groups, which are installed side by side on a vehicle front cross beam; a plurality of ground magnetic nails, which are arranged on a lane ground and correspond to positions of the magnetic switch groups; and a controller, which is used for controlling a driving speed of the vehicle in the lane by using interaction between the magnetic switch groups and the ground magnetic nails during vehicle forward driving or backward driving. Thus, human factors can be avoided, the automation degree of the vehicle is improved, lane driving safety can be effectively improved, driving and carrying efficiency is improved, guide rails and auxiliary wheels on both sides of the vehicle are effectively protected, and personnel and goods on both sides are protected.

The invention discloses an integrated controllable brake shaft for a flameproof electromagnetic mine car, belonging to the technical field of brake shafts for flameproof electromagnetic mine cars. An integrated controllable brake shaft for a flameproof electromagnetic mine car comprises a mine car body and four rollers arranged at the bottom thereof. The integrated controllable brake shaft for a flameproof electromagnetic mine car, the flow and reflux of brake oil will flow through the oil flow groove, and will drive the turbofan to rotate at high speed. The rotation of the turbofan causes the fan shaft to drive the cooling fan to rotate at high speed through the main gear and the slave gear. The rotation of the cooling fan generates wind, which is gathered through the wind gathering box and then discharged through the exhaust port, the air cooling pipe and the wind gathering port, so as to facilitate real-time cooling of the brake. In the process of braking and releasing the brake, the brake is cooled in real time and synchronously, which can not only improve the heat dissipation efficiency of the brake, but also reduce the wear of the brake, thereby extending the service life of the brake and the brake disc.
