Description

Technical Field

[0001] The utility model relates to the technical field of gearbox testing tooling, in particular to a gearbox oil level testing tool. Background Art

[0002] The gearbox, also known as the transmission, is an automotive accessory used to change the speed and torque from the engine, and can change the transmission ratio of the output shaft and the input shaft in a fixed or step-by-step manner. The gearbox has the functions of achieving reverse, changing the transmission ratio to adapt to different driving conditions, and using the neutral gear to cut off the power transmission without turning off the engine. It is widely used in the field of internal combustion engines.

[0003] A reasonable oil level is a necessary condition to ensure that the transmission has good shifting quality, maximizes its mechanical efficiency, and allows the transmission parts to operate normally. If the transmission oil level is low, the shifting quality of the vehicle will be poor and the parts will be at risk of wear. If the transmission oil level is high, the mechanical efficiency of the whole machine will be low and the fuel consumption of the whole vehicle will be high. Therefore, during the development stage of the manual transmission sample, the oil level of the transmission needs to be tested on the test bench to determine the amount of oil to be added to the transmission and ensure the cooling and lubrication of the internal structure of the transmission.

[0004] Conventional measurement methods generally use a professional level meter or a level dipstick inserted into the gearbox to determine the oil level. The level meter is relatively expensive and is not suitable for use in the early sample development stage. However, for some compact or irregular spaces, the level dipstick cannot accurately measure the oil level, and a simple tooling needs to be designed to assist in the measurement.
