Example 1
In accordance with a preferred embodiment of the present invention, and with reference to fig. 1-2, there is provided an axle final drive final cone bearing lubrication arrangement comprising:
an oil storage chamber e disposed adjacent to the driven bevel gear 6;
the oil inlet d is arranged on one side, far away from the driven bevel gear 6, of the oil storage cavity e;
the first oil inlet channel b is directly communicated with the oil inlet d and the first main cone bearing 2;
the second oil inlet channel c is directly communicated with the oil inlet d and the second main cone bearing 5; and
the oil storage cavity e and the oil inlet d are arranged in a shell 4 of the axle main speed reducer, and the first oil inlet channel b and the second oil inlet channel c are arranged in a main cone bearing support used for mounting the first main cone bearing 2 and the second main cone bearing 5.
Advantageously, the lubricating structure utilizes the driven bevel gear 6 to pump different flow speeds of oil, arranges high-low double oil inlet channels for drainage to ensure lubrication of the main cone bearing, and solves the problem of lubrication of the main cone bearing during low-speed starting and/or driving in a climbing road condition.
Preferably, through optimizing main reducer shell structural design, adopt splash lubrication, arrange two oil feed canals of high low level in main cone bearing department, guarantee that lubricated fluid carries the bearing position fast, guarantee especially when starting with the climbing operating mode at a low speed that bearing lubrication is abundant. For example, referring to fig. 2, which shows the main cone bearing lubrication structure under normal operation, the first oil inlet passage b is a low oil inlet passage, i.e., a relatively low position in the vertical direction, corresponding to high-speed forward, and the second oil inlet passage c is a high oil inlet passage, corresponding to low-speed start-up conditions. It can be understood that the lubricating oil carried and splashed by the driven bevel gear 6 rotating at a high speed flows into the first oil feed passage b at a higher speed, whereas the lubricating oil carried and splashed by the driven bevel gear 6 rotating at a low speed flows into the second oil feed passage c at a lower speed. Advantageously, the first and second main cone bearings 5 are in communication through an oil passage.
According to still another aspect of the present invention, the oil storage chamber e serves to collect the lubricating oil splashed by the rotation of the driven bevel gear 6.
According to still another aspect of the present invention, the first and second main cone bearings 2 and 5 are provided along an axial direction of the drive bevel gear 1, and the drive bevel gear 1 is engaged with the driven bevel gear 6.
According to still another aspect of the present invention, the first main cone bearing 2 is farther from the driven bevel gear 6 and the oil reservoir e than the second main cone shaft. Preferably, the driven bevel gear 6 meshes with a differential assembly 7. The main cone bearing is arranged on a main cone bearing seat 3.
According to still another aspect of the present invention, referring to fig. 1, the first main cone bearing 2 and the second main cone bearing 5 are communicated with each other through an oil passage, and a first connection between the first oil supply passage b and the first main cone bearing 2 and a second connection between the second oil supply passage c and the second main cone bearing 5 are adjacently disposed. For example, the first joint is disposed at the right end of the first main cone bearing 2, and the second joint is disposed at the left end of the second main cone bearing 5.
According to another aspect of the present invention, the first oil inlet channel b is further provided with an oil baffle table a.
According to still another aspect of the present invention, the second oil inlet passage c is a lubricating oil passage for low speed and/or climbing.
Preferably, after the vehicle is started, the driven bevel gear 6 pumps oil in the axle cavity into the oil storage cavity e, the rotating speed of the driven bevel gear 6 is slow during starting, the flow rate of the oil pumped into the oil storage cavity e is slow, and the oil overflows from the oil inlet d and directly flows into the second oil inlet channel c along the wall of the main reducer casing; the vehicle is accelerated, the flow velocity of oil is accelerated, the oil and the oil inlet d generate impact to directly splash and impact the driven helical gear, and the oil falls down and is collected by the oil baffle table a to flow into the first oil inlet channel b; when the vehicle runs to the road condition with an overlarge climbing angle, the oil discharged from the oil inlet d can not splash and enter the first oil inlet channel b, and can also be led to the position of the second oil inlet channel c through the flowing along the wall of the main reducer casing, so that the bearing can be kept to be soaked by sufficient lubricating oil all the time in the running process of the vehicle.
The utility model can obtain one or more of the following technical effects:
1. the double oil ducts are adopted for lubrication, so that the lubricating effect on the bearing is enhanced;
2. the bearing can be fully lubricated even under the road conditions of low-speed starting and/or overlarge climbing angle;
