Problems solved by technology

[0003] At present, AT transmissions need an oil drain bolt and an oil level inspection bolt, and these two bolts are usually combined. Hexagon socket bolt, because the internal hexagon socket bolt for oil level inspection in the middle is small, it is easy to slip teeth during disassembly, resulting in the oil level inspection bolt cannot be disassembled, therefore, we propose an AT transmission oil level inspection bolt assembly

Abstract

The invention discloses an AT transmission oil level inspection bolt assembly. The AT transmission oil level inspection bolt assembly comprises a first bolt and a second bolt, a movable nut is mountedat one end of the first bolt, a pipe cavity is formed in the first bolt, a first internal thread is formed in one end, far away from the bolt head of the first bolt, of the pipe cavity, a connectingpipe is arranged on one side of the movable nut, an external thread is arranged on the inner wall of the connecting pipe, a second internal thread with the same thread pitch as the movable nut is arranged on the inner wall of the connecting pipe, a counterbore communicating with the pipe cavity is formed in one end of the first bolt, one end of the second bolt penetrates through the first bolt through the counterbore, and one end of the second bolt is in threaded connection with the connecting pipe and the movable nut in sequence. Screw slipping is not prone to happening in the dismounting process, dismounting is more convenient, the assembly can be taken out and dismounted from the other end in the screw slipping process, then a screw slipping assembly can be taken out, and maintenance and replacement are convenient.

Description

technical field [0001] The invention belongs to the technical field of transmissions, and in particular relates to an oil level inspection bolt assembly of an AT transmission. Background technique [0002] The transmission is a mechanism used to change the speed and torque from the engine. It can change the transmission ratio of the output shaft and the input shaft in fixed or stepwise steps, also known as the gearbox. Speed ​​changer is made up of speed change transmission mechanism and operating mechanism, and some automobiles also have power output mechanism. Most of the transmission mechanisms are driven by ordinary gears, and some are driven by planetary gears. Ordinary gear transmission transmission mechanisms generally use slip gears and synchronizers, etc. AT transmissions are automatic transmissions, also known as automatic gears. [0003] At present, AT transmissions need an oil drain bolt and an oil level inspection bolt, and these two bolts are usually combined...
