Abstract

The invention provides a connecting structure of a torque converter and a transmission case breathing cap, wherein the transmission case and the torque converter are arranged in a close manner, an oil filling breathing port of the transmission case and a breathing port of the torque converter are connected to an oil filling block at a high position through a pipeline, and the oil filling block is provided with an oil filling port. Above-mentioned technical scheme breathes the cap with the torque converter and gearbox and passes through the tube coupling, and the hydraulic oil that gets rid of the torque converter through breathing the cap passes through the oil tank that the pipeline discharged the gearbox, and it is fast promptly to increase a little valve block on this connection return circuit simultaneously, increases the oil filler hole on this oil filler block, conveniently refuels, has guaranteed the normal breathing demand of torque converter simultaneously.

Description

Connecting structure of torque converter and gearbox breathing cap

Technical Field

The invention relates to the field of 20T mining and transportation vehicles, in particular to a connecting structure of a torque converter and a gearbox breathing cap.

Background

A double-variable system of a torque converter and a gearbox can be used on a 20T mining and transportation vehicle, hydraulic oil in the torque converter can be discharged outwards through a breathing cap in the use process, an oil port with a high breathing cap is adopted, the appearance of the equipment is influenced, and the spatial arrangement of the equipment is also influenced.

Disclosure of Invention

The invention aims to provide a connecting structure of a torque converter and a gearbox breathing cap, which can avoid the outward discharge of hydraulic oil of the torque converter and is convenient for the filling of the hydraulic oil of the gearbox.

In order to achieve the purpose, the invention adopts the following technical scheme, and the connecting structure of the torque converter and the gearbox breathing cap is characterized in that: the gearbox is close to arrange and the oiling of gearbox breathes mouthful and torque converter breathes the mouth and is connected the piece of refueling to high-order department via the pipeline with torque converter's breathing mouth, has the oil filler hole on the piece of refueling.

Above-mentioned technical scheme breathes the cap with the torque converter and gearbox and passes through the tube coupling, and the hydraulic oil that gets rid of the torque converter through breathing the cap passes through the oil tank that the pipeline discharged the gearbox, and it is fast promptly to increase a little valve block on this connection return circuit simultaneously, increases the oil filler hole on this oil filler block, conveniently refuels, has guaranteed the normal breathing demand of torque converter simultaneously.

Drawings

FIG. 1 is a schematic view of the structure of the present invention.

Detailed Description

In the connection structure of the torque converter and the transmission breather cap shown in fig. 1, the transmission 10 is arranged adjacent to the torque converter 20, and the oil filling breather 11 of the transmission 10 and the breather 21 of the torque converter 20 are connected to the oil filling block 30 at a high position through a pipeline, and the oil filling block 30 is provided with an oil filling opening 31. The scheme solves the problem that the oil of the torque converter 20 is discharged outside at will, namely the hydraulic oil of the torque converter 20 is conveyed into the gearbox 10 through a pipeline, and the hydraulic oil can be injected through the oil filling port 31 when the gearbox 10 needs to be filled with oil.

Preferably, a vertical pipe 41 extending downward is connected to the bottom of the fueling block 30, the other two ports of the tee-pipe joint 42 connected to the lower end of the vertical pipe 41 are respectively connected to a first pipe 43 and a second pipe 44, the first pipe 43 is communicated with the fueling breather port 11 at the upper portion of the transmission 10 via a first elbow 431, and the second pipe 44 is communicated with the breather port 21 at the upper portion of the torque converter 20 via a second elbow 441.

The connection of the pipelines can be conveniently realized by arranging the pipe joints such as the elbow, the tee joint and the like.

More preferably, the first pipeline 43 and the second pipeline 44 are flexible pipes and are arranged horizontally as a whole, and the height of the first pipeline 43 is equal to or lower than the height of the second pipeline 44. The precision requirements of the installation positions of the torque converter 20 and the gearbox 10 can be reduced when the flexible pipes are connected, and in combination with the arrangement scheme that the height of the first pipeline 43 is equal to or lower than that of the second pipeline 44, the oil liquid discharged by the torque converter 20 can be ensured to flow to the gearbox 10, the gas part can be discharged from the oil filling port 31, the generated oil vapor can be properly condensed through the pipeline to flow back, and the discharge of the oil vapor is reduced.

In order to ensure the cleanness of the passage, a dust cover is additionally arranged above the oil filling port 31, and an air filter is arranged on the passage in the oil filling block 30 or at the orifice of the oil filling port 31. It should be noted here that the air filter and the dust cover are not shown, so that the dust can be effectively intercepted.
