Description

Technical Field

[0001] The invention relates to the technical field of engines, and in particular to an integrated oil drain plug. Background Art

[0002] The reducer is an independent closed transmission device between the prime mover and the working machine, which is used to reduce the speed and increase the torque to meet the working needs. The reducer oil filling port and oil level observation port are usually designed to be integrated in one location, such as the attached Figure 1 As shown, the refueling port 7 is located on the side of the differential housing. When the reducer lubricating oil leaks, the lubricating oil level of the reducer cannot be observed without disassembling the powertrain, and direct refueling may cause oil overflow and environmental pollution; disassembling the powertrain to observe the oil level will waste man-hours; at the same time, the location of the refueling port is limited by the observation of the oil level, and can only be designed on the side of the differential housing, which makes the refueling process poor.

[0003] There are three methods to detect the oil level in the reducer: volume estimation method, oil level check plug method and on-vehicle dipstick method. The volume estimation method mainly releases all the oil in the transmission and estimates the amount of oil stored in the transmission and the oil level by measuring its volume. This method is generally applicable to manual transmissions. The oil level check plug method is to observe whether an oil level check plug preset on the side of the transmission can release oil, and combine it with the measurement of the amount of oil released or added to calculate the amount of oil stored in the transmission and estimate the oil level. For the on-vehicle dipstick method, it uses the oil pipe dipstick on the transmission to determine the oil level of the transmission by reading the oil level line on the dipstick.

[0004] Document (CN 220979604 U) discloses an oil drain plug for an oil pan, comprising: a first connecting member; a second connecting member, wherein the circumference of the first connecting member and the circumference of the second connecting member are meshed and connected when the torque is within a preset range, and the first connecting member and the second connecting member can rotate relative to each other when the torque is greater than the preset torque; the second connecting member is used to seal and connect with the oil drain port of the oil pan. The operation of the oil level check plug is very complicated, time-consuming and material-intensive, and the oil level check hole and plug need to be specially made. Summary of the invention

[0026] A method for using an integrated oil drain plug:

[0027] When the reducer lubricating oil is found to be leaking, there is no need to disassemble the powertrain. Place the vehicle on a lift or in a ditch, open the dipstick screw plug 4, and use a measuring cup to collect the lubricating oil overflowing from the hollow tube dipstick. If there is no lubricating oil overflowing, slowly add lubricating oil from the refueling port, 0.2L each time, until the lubricating oil flows out in drops, tighten the dipstick screw plug 4, and then add 0.1L of lubricating oil from the refueling port; if there is lubricating oil overflowing, wait until the lubricating oil flows out in drops, tighten the dipstick screw plug 4, observe the amount of lubricating oil in the measuring cup, if it is less than 0.1L, add 0.1L of lubricating oil from the refueling port.

[0028] Example:

[0029] As attached Figure 7As shown, an integrated drain plug includes: a hollow tube dipstick 1, a magnetic sheet 2, a drain plug 3, a dipstick plug 4, a sealing gasket 5 and an O-ring 6. The integrated drain plug is threadedly connected to the reducer housing 8. The lubricating oil level 9 in the reducer housing 8 exceeds the front end of the hollow tube dipstick 1. The outer diameter of the hollow tube dipstick 1 is a hollow tube with an outer diameter of ψ2mm. After unscrewing the dipstick plug 4, no oil can flow out of the hollow tube of the hollow tube dipstick 1. Slowly pull out the hollow tube dipstick 1 until oil starts to leak out from the hollow tube dipstick 1. Collect the leaked oil in a measuring cup, continue to pull out the hollow tube dipstick 1 until the oil level in the measuring cup reaches 0.1L, and mark it on the hollow tube dipstick 1. Measure the length from the marked position of the hollow tube dipstick 1 to the top, minus 11.7mm, which is the required size of the hollow tube dipstick. When it is necessary to determine whether the reducer is short of oil, it is only necessary to open the dipstick screw plug 4 and use a measuring cup to collect the lubricating oil overflowing from the hollow tube dipstick 1. If no lubricating oil overflows, slowly add lubricating oil from the refueling port, 0.2L each time, until the lubricating oil flows out in drops, and then add 0.1L of lubricating oil from the refueling port; if lubricating oil overflows, wait until the lubricating oil flows out in drops, observe the amount of lubricating oil in the measuring cup, if it is less than 0.1L, add 0.1L of lubricating oil from the refueling port.
