Quick connecting mechanism of gearbox and hydrodynamic retarder

Abstract

The invention discloses a quick connecting mechanism of a gearbox and a hydrodynamic retarder, and relates to the technical field of automobile machinery. The mechanism comprises a transition shell and a rear cover seat body; mounting screw holes are formed in the transition shell and the rear cover seat body; the rear cover seat body is mounted on the transition shell through the matching of the mounting screw holes and fixing bolts; and a lubricating oil cavity is formed in the transition shell. According to the quick connecting mechanism of the gearbox and the hydrodynamic retarder, a gear transmission cavity and the lubricating oil cavity are extended and added on the basis of an original truck gearbox rear cover, so that the fixation and the transmission of a hydraulic retarder gear transmission system are realized on the basis of meeting all original functions of the gearbox, the mutual transmission of partial output power of the gearbox and all braking power of the hydrodynamic retarder is achieved, the lubrication and the cooling of the gear transmission system and a bearing are achieved, the installation and the fixation of the hydrodynamic retarder are achieved, and the hydrodynamic retarder utilizes a truck transmission shaft to brake a truck.

Description

technical field [0001] The invention relates to the technical field of automobile machinery, in particular to a quick connection mechanism for a gearbox and a hydraulic retarder. Background technique [0002] At present, the brand trucks on the market can generally be equipped with Fast or Voith retarder at the rear of the gearbox. The basic function is to fix and support the Fast retarder and the gear transmission mechanism and to fix and support the Foith YIT retarder and gear transmission mechanism, but the ordinary gearbox back cover obviously cannot fix the retarder, and there are still some defects; [0003] On the one hand, the existing gearbox rear cover cannot satisfy the newly applied hydraulic retarder, and its gear transmission mechanism is installed and fixed; on the other hand, part of the gearbox cannot output power and the hydraulic retarder All the braking power is transmitted to each other. At the same time, the existing gearbox back cover cannot implement...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a quick connection mechanism for a gearbox and a hydraulic retarder, so as to solve the problem that the newly applied hydraulic retarder and the gear transmission mechanism cannot be installed and fixed in the above-mentioned background technology, and the gearbox cannot be connected. Part of the output power of the hydraulic retarder and the entire braking power generated by the hydraulic retarder are transmitted to each other, and the problem of lubrication and cooling of the bearing and gear transmission mechanism of the hydraulic retarder cannot be implemented.
