With the development trend of energy conservation and emission reduction in the world, the importance of lightweight design is more and more prominent. As a comprehensive transmission device of a core component of the tracked vehicle, the light weight and high power density are realized, and the integrated transmission device has important significance for the whole vehicle to carry out combat tasks. The wet clutch is a core part of the integrated transmission device, is an actuating mechanism for realizing power transmission and cut-off of the integrated transmission device, and is generally installed on a main transmission shaft of the integrated transmission device. The wet clutch is designed in a light weight mode, so that the self-generated weight of the wet clutch can be reduced, the advantage that the rotational inertia of the wet clutch is reduced can be utilized, the rotating speed of a transmission shaft is increased, and the transmission power is increased. Therefore, the lightweight clutch cylinder sleeve structure is developed, the weight of the clutch is reduced, and the lightweight clutch cylinder sleeve structure is a precondition and an effective means for greatly improving the power density of the comprehensive transmission device.
The cylinder sleeve of the existing wet clutch is formed by forging alloy structural steel and then machining, and besides the large self weight, the large rotational inertia is not beneficial to improving the transmission rotating speed, so that the high power density of the comprehensive transmission device is restricted; according to the existing structure, the clutch cylinder sleeve is directly made of high-strength aluminum alloy, so that the weight can be reduced, but the spline part of the cylinder sleeve cannot overcome alternating stress generated in the working process of a transmission shaft, and the phenomenon of local crushing is easily generated to cause part failure.

In order to solve the technical problem, the utility model provides a simple structure is compact, and the quality is little, is favorable to promoting transmission rotational speed and transmission power, realizes the driven lightweight cylinder liner that is used for wet clutch of high power density.
The utility model adopts the technical proposal that: a lightweight cylinder liner for a wet clutch includes a cylinder body portion and a connecting portion that are coaxially connected; the connecting part is cylindrical, and a spline groove is arranged on the inner wall of a central hole of the connecting part; the cylinder body part is positioned outside the connecting part and comprises an annular bottom plate and an annular plate, one end of the annular plate is connected with the bottom plate, the bottom plate is connected with one end of the connecting part, and the cylinder body part and the connecting part enclose an annular cavity gap; a plurality of grooves are formed in one end face of the annular plate of the cylinder body portion, and a check ring installation groove is formed in the inner wall of the annular plate.
In the lightweight cylinder sleeve for the wet clutch, the connecting portion is provided with the lubricating oil hole, the oil inlet of the lubricating oil hole is formed in the end face of the connecting portion, the oil outlet of the lubricating oil hole is formed in the side face of the connecting portion, and the oil outlet is located in an annular cavity formed by the cylinder body portion and the connecting portion in an enclosed mode.
In the above-described lightweight cylinder liner for a wet clutch, the cylinder body portion and the connecting portion are each made of an aluminum alloy.
In the lightweight cylinder sleeve for the wet clutch, the connecting part is continuously cast on the cylinder body part by adopting a semi-solid forming process.
In the lightweight cylinder sleeve for the wet clutch, the side wall of the connecting part is provided with the bosses with arc-shaped sections, the number of the bosses is the same as that of the lubricating oil holes, and the bosses are coaxial with the corresponding lubricating oil holes.
Compared with the prior art, the beneficial effects of the utility model are that: a) the utility model has simple and compact structure, and under the same vehicle using condition, the wet clutch of the utility model has lighter weight and approximately reduces weight by 50-60 percent; b) the utility model has small rotational inertia, which is beneficial to realize high power density transmission by increasing the transmission speed and the transmission power; c) the utility model discloses the difference aluminum alloy is made, and the heat conductivity is good, can derive the heat that the smooth mill of clutch friction disc produced fast.

Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1-2, the utility model comprises a cylinder body part 1 and a connecting part 2 which are coaxially connected; the connecting part 2 is cylindrical, and a spline groove is formed in the inner wall of a central hole of the connecting part 2. The cylinder body part 1 is located the connecting portion 2 outside, and cylinder body part 1 includes annular bottom plate 11 and crown plate 12, and the one end and the bottom plate 11 of crown plate 12 are connected, and bottom plate 11 is connected with the one end of connecting portion 2, and cylinder body part 1 encloses into an annular lacuna with connecting portion 2. A plurality of grooves 13 are provided on one end surface of a ring plate 12 of the cylinder body portion 1, and a retainer ring installation groove 14 is provided on the inner wall of the ring plate 12.
The connecting portion 2 is provided with a lubricating oil hole 21, an oil inlet of the lubricating oil hole 21 is formed in the end face of the connecting portion 2, an oil outlet of the lubricating oil hole 21 is formed in the side face of the connecting portion, and the oil outlet is located in an annular cavity formed by the cylinder portion 1 and the connecting portion 2 in a surrounding mode.
