An oil circuit circulation structure of an intermediate shaft brake

Abstract

The invention provides an oil path circulation structure of an intermediate shaft brake. The oil path circulation structure comprises an intermediate shaft, a roller bearing, a gearbox front shell anda brake shell, wherein the roller bearing sleeves the outer part of the intermediate shaft; the gearbox front shell sleeves the outer part of the roller bearing; the brake shell is fixedly connectedwith the gearbox front shell; a first end of the intermediate shaft is propped against a piston in the brake shell; a plurality of steel sheets and friction sheets sleeve the outer part of the first end; the friction sheets are positioned between the two adjacent steel sheets; the steel sheets and the friction sheets are positioned between the roller bearing and the piston; a plurality of first oil passing grooves are formed in the corresponding steel sheets close to the roller bearing; oil inlet ends of the first oil passing grooves communicate with an oil inlet channel at the outer part of the gearbox front shell through a first oil path; and oil outlet ends of the first oil passing grooves communicate with the inner part of the roller bearing through a second oil path. Through the adoption of the oil path circulation structure, the roller bearing is lubricated when the piston is compressed, and the service life of the roller bearing is prolonged.

Description

technical field [0001] The invention belongs to the field of gearbox processing and design, and in particular relates to an oil circuit circulation structure of an intermediate shaft brake, which is suitable for lubricating a roller bearing when a piston is pressed tightly, thereby improving the service life of the roller bearing. Background technique [0002] At present, in the intermediate shaft brakes of domestic commercial vehicles, the lubricating oil is splashed everywhere for lubrication mainly through the high-speed rotating shaft teeth, which is difficult to meet the lubrication requirements of the intermediate shaft brakes under different braking conditions. [0003] Chinese patent: authorized public number CN109163031A, authorized announcement date of January 08, 2019 discloses an AMT intermediate shaft braking structure, including an intermediate shaft extending from the gearbox housing to the brake housing, and the extension part of the intermediate shaft A plur...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the problem that the lubricating oil cannot lubricate the roller bearings when the piston is compressed, and provide an oil circuit circulation structure of the intermediate shaft brake in which the roller bearings are lubricated when the piston is compressed
