A high-speed locomotive driving gearbox for improving oil return performance. When the gearbox operates, lubricating oil leaked from labyrinth seals of an input shaft and an output shaft returns to an oil return buffer cavity first, and then flows back to an oil sump from the oil return buffer cavity. When the rotation speed of the gearbox increases, causing the internal pressure thereof to rise and hinder the return of the lubricating oil to the gearbox oil sump, the lubricating oil leaked from the labyrinth seals may return to and gather in the oil return buffer cavity first, and finally flows back to the oil sump of the gearbox once the rotation speed of the gearbox is reduced, thereby enabling smooth return of the lubricating oil leaked from the labyrinths seals. The gearbox is connected to an external environment by means of a ventilation system; when the internal pressure of the gearbox is greater than the pressure of the external environment, an internal airflow flows to the external environment through the ventilation system, such that the internal pressure of the gearbox is reduced; and when the internal pressure of the gearbox is less than the pressure of the external environment, an airflow flows from the external environment into the gearbox through the ventilation system, such that the internal pressure of the gearbox is increased, thereby achieving the aim of balancing the internal pressure and external pressure of the gearbox.

For the problem of inadequate effectiveness of existing wheel rail adhesion improvement schemes, a wheel rail anti-slip control method for a rail vehicle is provided. Axle speed information of each axle is obtained by means of a corresponding speed sensor, a target axle to which wheel slippage occurs is located, the severity of wheel slippage is determined, and on this basis, the amount of sand needing to be delivered by a sandbox is determined. Further, the pressure of a brake cylinder is controlled by means of an anti-slip valve so as to mitigate the wheel slippage condition, and the sandbox is controlled to execute a sand delivery action on the basis of said determined amount, such that coordination between an anti-slip system and a sand delivery system in the railway vehicle is achieved.

A warning method and device for thermal runaway of a battery, and a storage medium, which relate to the field of thermal runaway of batteries. The change rate of the concentration of a target gas, which is generated by a target battery during a thermal runaway process, is selected as a characteristic parameter.

Abrégé

Disclosed are a vehicle-end jumper cable mounting structure and a cable resetting method. The vehicle-end jumper cable mounting structure comprises at least two guide rails longitudinally arranged at the bottom of a vehicle end, and a cable fixing clamp, which is transversely arranged at the bottom of the vehicle end and configured to fix a vehicle-end jumper cable, wherein the cable fixing clamp is mounted on the guide rails by means of a rolling support mechanism, and the cable fixing clamp can longitudinally move along the guide rails. The present invention can solve the problems that a cable is prone to making contact with a rail face, and the end of a vehicle-end jumper cable is easily broken.
