Description

Technical Field

[0001] The utility model relates to the technical field of differentials, in particular to a differential with a built-in oil storage structure. Background Art

[0002] The automobile drive axle is located at the end of the transmission system. Its main function is to increase the torque transmitted by the drive shaft or transmission, and at the same time distribute the torque to the left and right drive wheels or the front and rear axles, so that the left and right drive wheels or the front and rear axles have the differential function required by the vehicle's driving kinematics. The differential function is mainly achieved through the differential. When the differential is working, its planetary gears not only revolve around the center line of the half-shaft, but also rotate on their own. The rotation of the planetary bevel gears revolves around the center line of the cross shaft journal of the differential. At this time, the inner hole of the planetary bevel gear and the cylindrical surface of the cross shaft journal produce relative friction.

[0003] Existing differentials experience wear at low speeds or under special operating conditions due to friction between gears and other components, further impacting their service life and performance. Furthermore, most differentials lack a corresponding oil reservoir, preventing continuous lubrication with oil. This increases wear at the meshing points of the differential gears and shortens their service life. To address this, we propose a differential with a built-in oil reservoir. Utility Model Content
