Description

Technical Field

[0001] The present invention relates to testing equipment and components for underground battery scraper transmission systems. Background Art

[0002] With the development of new energy sources, trackless equipment in underground mines has also entered a new era of development. Compared to traditional diesel scrapers, the transmission system of underground battery scrapers features a major change: the engine is replaced with an electric motor. Another major change is that the battery scraper no longer uses a torque converter, with the motor directly connected to the gearbox. This advantage is faster response and greater sensitivity. However, it also presents two problems: the hydraulic oil pump and cooling oil pump were previously installed on the torque converter. With the removal of the torque converter, there is no place to install the oil pumps. The motor is a variable-speed motor. During shoveling, the required traction force can cause the motor to stall. This stops the motor from rotating, and the pressure oil required for gear shifting is lost, rendering the gear shift ineffective. Summary of the Invention
