Description

Isolator assembly

Technical Field

The invention relates to the technical field of isolators, in particular to an isolator assembly.

Background

When an automobile engine is started, a starter drives a flywheel of the engine to rotate, and then the engine can be started; after the engine is ignited and started, the rotating speed of the flywheel can quickly exceed the rotating speed of the starter, so that in order to avoid the reverse driving of the engine to rotate the starter, a one-way clutch, also called an overrunning clutch, is arranged between the engine and the starter, and is separated after the rotating speed of the engine exceeds the rotating speed of the starter, so that the engine is prevented from driving the starter to rotate, and the electric vehicle is also provided with the one-way clutch; when the electric vehicle is shifted from a high gear to a low gear, the output shaft still has a higher rotating speed because the output shaft is just separated from the high-speed gear, and therefore after the output shaft is connected with the low-speed gear, a speed reduction process is required for the output shaft to have the same speed with the low-speed gear, otherwise the output shaft can reversely drive the low-speed gear to rotate, or the low-speed gear is subjected to tooth beating, so that impact is formed on the gear, the gear is rapidly damaged, and therefore the one-way clutch is also arranged on the electric vehicle, and the output shaft is prevented from reversely driving the low-speed gear.

Because the isolator subassembly is in the use, there is friction between output shaft and the planet gear axle, need to coat lubricating grease between the diaxon in order to reduce the loss that the friction produced, because the clearance between output shaft and the planet gear axle is less, it is difficult to coat lubricating grease to the clearance inside, therefore we improved this, proposed the isolator subassembly.

Disclosure of Invention

Aiming at the defects of the prior art, the invention provides an isolator assembly, which solves the problems that at present, friction exists between an output shaft and a planetary gear shaft, lubricating grease needs to be coated between the output shaft and the planetary gear shaft in order to reduce the loss generated by the friction, and the lubricating grease is difficult to coat in a gap because the gap between the output shaft and the planetary gear shaft is small.

In order to achieve the purpose, the invention is realized by the following technical scheme: the one-way device assembly comprises a planet wheel shaft, wherein a spline close to a disc of the planet wheel shaft is arranged on the outer wall of the planet wheel shaft, an output shaft is sleeved on the planet wheel shaft, the inner wall of one end of the output shaft is meshed with the spline, the one end of the output shaft, which is meshed with the spline, is sleeved with the one-way device, an inner ring lubricating device is arranged on the surface of one end, which is far away from the one-way device, of the output shaft, the inner ring lubricating device comprises a plurality of plug mounting grooves, each plug mounting groove is formed in the surface of one end of the output shaft, and a retainer ring positioned on the output shaft is movably sleeved on the outer wall of one end of the planet wheel shaft.

The invention provides a one-way clutch assembly. The method has the following beneficial effects: lubricating grease can be added between the planet wheel shaft and the output shaft through the inner ring lubricating device, and the difficulty of adding lubricating oil is greatly reduced.
