Problems solved by technology

Therefore, when the distribution sleeve is supplying oil, once the oil supplied to a certain coupler is connected to another coupler, the air loss of the other idling coupler will increase, which will have a greater braking effect on the power-assisted coupler. , reduce the boost power of the hydraulic coupling

Embodiment Construction

[0023] In order to make the purpose, content, and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] In order to solve the problems in the prior art, the present invention provides a distribution sleeve for a double coupler. The distribution sleeve 121 is a stepped hollow protrusion, which includes: a first annular body 101, a second annular body 102 and The multi-faceted annular cylinder 103; the first annular body 101, the second annular body and the multi-faceted annular cylinder are coaxial with each other; the first annular body 101, the second annular body and the multi-faceted annular cylinder The cylinder is formed in one piece;

[0025] The outer peripheral edge of the first annular body 101 is provided with a circle of bolt holes 104, and its outer peripheral edge is fixedly connected with the bearing...

Abstract

The invention belongs to the fields of mechanical manufacturing and vehicle design, and in particular relates to a flow distribution sleeve for a double coupler in a static-dynamic-hydraulic compound steering mechanism of a crawler vehicle, which is used to prevent the occurrence of oil spillage. In the present invention, in the area between the second dynamic seal and the third dynamic seal of the distribution sleeve, an oil-containing inner ring cavity is opened first, and a gap is opened at the vertical bottom of the inner ring cavity, and the gap leads to the atmosphere, so that when When a coupler is working, the working oil passing through the oil inner ring cavity will slide down to the bottom due to gravity and leak out through the gap, which prevents the two couplers from passing through each other. After physical development and bench test verification, the invention has achieved the expected research purpose, so that when a certain coupler is working, the phenomenon of mutual oil flow will not occur, and the boosting effect of the booster coupler is guaranteed.

Description

technical field [0001] The invention belongs to the field of machinery manufacturing and vehicle design, and in particular relates to a flow distribution sleeve for a double coupler in a static-dynamic fluid composite steering mechanism of a crawler vehicle, which can prevent the occurrence of the phenomenon of oil stringing. Background technique [0002] At present, dynamic and static hydraulic compound steering is one of the main schemes adopted in the steering system of tracked vehicles. The dynamic and static hydraulic compound steering system is the guarantee for the rapidity, stability and reliability of tracked vehicles, especially large-tonnage tank armored vehicles. Its working principle is: when the tracked vehicle turns to one side, pull the swash plate of the hydraulic pump to one side, and when the pressure on one side of the hydraulic pump motor increases to a certain value, the coupling on one side starts to receive the oil supplied by the flow sleeve to interv...
