Problems solved by technology

At present, the automatic transmission differential lubrication method in the market generally adopts the splash lubrication method, and there is no special lubrication mechanism for forced lubrication of the differential. The splash lubrication effect is not good and the reliability is not high. In addition, the old-fashioned lubrication method is not accurate. Effectively carry out targeted lubrication for a certain part

Embodiment Construction

[0020] The present invention will be specifically described below in conjunction with the accompanying drawings.

[0021] Such as Figure 1-3 As shown, the differential auxiliary lubricating system of the present invention includes a lubricating oil pipe 3, a locking plate 2 and a locking plate fixing bolt 1, and these components are installed on the torque converter housing 7, wherein the lubricating oil pipe 3 is installed on the torque converter housing At the reserved oil passage on the body 7, the locking plate 3 is Y-shaped, one end of which is locked to the bearing outer ring of the torque converter housing by the locking plate fixing bolt 1; the second end is pressed on the lubricating oil pipe 3, thereby fixing The lubricating oil pipe 3 passes through the small hole on the lubricating oil pipe 3 to carry out forced lubrication for the center gear position of the differential.

[0022] In addition to supplying the lubricating medium to the differential, this lubricat...

Abstract

The invention discloses an auxiliary lubricating system of a differential, comprising a lubricating oil pipe (3), a locking piece (2) and a locking piece fixing bolt (1), wherein the lubricating oil pipe (3) is arranged at an oil passage position reserved on a torque converter shell (7); one end of the locking piece is locked on the torque converter shell (7) by the locking piece fixing bolt (1), and the other end thereof presses the lubricating oil pipe (3), thus fixing the lubricating oil pipe (3); and the lubricating oil pipe (3) passes through a small hole thereon to carry out forced lubrication on the position of a central gear of the differential. The auxiliary lubricating system has compact and simple structure, convenient manufacture and assembly and high reliability, thus solving the difficulty of lubrication of an automatic transmission differential with little oil amount for the gear and difficult lubrication, relieving the wear of the gear of the differential and prolonging the service life of the differential.

Description

technical field [0001] The invention belongs to the field of automobile transmissions, and in particular relates to an auxiliary lubricating system for differential gears. Background technique [0002] As we all know, the automatic transmission has gradually become the standard configuration of the best-selling models in the market because of its precise mechanism, fast execution, and excellent shift quality. However, its internal structure is extremely complicated, and the establishment of the lubrication system, especially the differential assembly Lubrication is extremely critical. At present, the automatic transmission differential lubrication method in the market generally adopts the splash lubrication method, and there is no special lubrication mechanism for forced lubrication of the differential. The splash lubrication effect is not good and the reliability is not high. In addition, the old-fashioned lubrication method is not accurate. Effectively carry out targeted ...
