Description

Technical Field

[0001] The utility model belongs to the technical field of clutch housing connection, and relates to a transition structure used for connecting a clutch and a booster pump, and a clutch housing. Background Art

[0002] In order to continuously expand the market of C6J55T, it is necessary to gradually match high-end buses. However, the current existing clutch booster pump connection form is mostly direct contact with the clutch housing, and the booster pump is connected by bolts. However, there are many types of clutches. The same clutch housing needs to change its structure to match different booster pumps because of its different connection forms with the booster pump. This increases the frequent mold opening process and mold opening cost to a certain extent. On the other hand, due to the obvious boundary between light trucks and light buses, the matching of the housing connection is low, which brings great inconvenience to the subsequent OEM application matching. Utility Model Content

[0003] The utility model aims to solve the problem that there are many types of clutch housings in the prior art and the compatibility is low when connected with different power-boosting pumps, and provides a transition structure and a clutch housing for connecting a clutch and a power-boosting pump.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A transition structure for connecting a clutch and a booster pump, characterized in that it comprises a transition plate body, and a hydraulic piston hole is provided on the transition plate body;

[0006] A connecting hole is provided on the transition plate body, and a groove is provided on one end surface of the transition plate body, wherein the groove is used for matching and connecting with a power booster pump to be connected.

[0007] The further improvement of the utility model is:

[0008] The grooves are symmetrically arranged along the hydraulic piston hole, and a threaded hole is arranged in each groove.

[0009] The depth of the groove is 8 mm.

[0010] The connecting holes are arranged on both sides of the groove.

[0011] There are four connecting holes.

[0012] The transition plate body is a rectangular structure.

[0013] Chamfers are arranged at the four corners of the rectangular structure.

[0014] The main body of the transition plate is made of alloy steel.

[0015] A clutch housing comprises the transition structure described in any one of the utility models.

[0017] The utility model discloses a transition structure for connecting a clutch and a power-boosting pump, comprising a transition plate main body, a hydraulic piston hole being provided on the transition plate main body, so that the hydraulic piston in the power-boosting pump can extend into the clutch housing to provide power without affecting the coordinated operation of the clutch and the power-boosting pump, and a groove being provided on one end surface of the transition plate main body. When the clutch needs to match the two-hole power-boosting pump, the groove can cooperate with the boss on the two-hole power-boosting pump, and the boss on the two-hole power-boosting pump extends into the groove to realize the fixed connection of the two-hole power-boosting pump. When the clutch needs to be connected to the four-hole power-boosting pump, the plane structure on the other side of the transition plate main body is connected to the power-boosting pump. At this time, the connecting holes can be matched and fixed. The device can be assembled on the front or back side according to the structure of the power-boosting pump to be connected, can adapt to the assembly of power-boosting pumps of various different models, has a high degree of matching, does not need to frequently replace the clutch housing, reduces the mold opening process, saves the mold opening cost, realizes the unification of light trucks and light buses, improves the interchangeability of the transmission, and is beneficial to the later maintenance and management.

[0018] Furthermore, in the utility model, the depth of the groove is 8 mm, so that the hydraulic piston hole retains a certain thickness, ensuring that the housing and the power pump are connected while being able to seal the power pump push rod to a certain extent, ensuring that road splashes do not enter the housing.

[0019] Furthermore, in the utility model, the main body material of the transition plate is alloy steel, which has good strength, rigidity and wear resistance as a transition plate. After processing, it can be used without heat treatment, thus saving subsequent processing steps. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Furthermore, in this embodiment, the hydraulic piston hole 2 is opened at the center position of the transition plate body 1, and the grooves 4 are symmetrically opened on both sides of the hydraulic piston hole 2. The grooves 4 cooperate with the bosses on the two-hole power-assisting pumps to be connected. The bosses can be embedded in the grooves 4 and matched and connected through the threaded holes opened in the grooves 4.

[0035] In this embodiment, the structure of the groove 4 is not limited and can be adjusted according to the boss structure of the power-boosting pump to be connected, as long as the matching connection of the power-boosting pump can be achieved.

[0036] Furthermore, in this embodiment, the groove 4 is sunken by about 8 mm, which meets the design requirements while striving for light weight.

[0038] Furthermore, in this embodiment, four connecting holes 3 are provided along the edge of the transition plate body 1, and the connecting holes 3 are used to assemble a four-hole power-boosting pump. When assembling the four-hole power-boosting pump, the side of the transition plate body 1 without the groove 4 is assembled and connected to the power-boosting pump.

[0039] Furthermore, in this embodiment, the transition plate body 1 is a rectangular structure, and the transition plate body 1 can also adjust its structure according to the structure of the clutch housing as long as it does not interfere with the assembly of the clutch and the power pump. Furthermore, chamfers are set at the four corners of the rectangular structure to avoid wear on the housing during assembly.

[0040] Furthermore, in this embodiment, the material of the transition plate body 1 is alloy steel, specifically Q235 alloy steel, which has good strength, rigidity and wear resistance as a transition plate, and can be used without heat treatment after processing.

[0045] If a two-hole booster pump is connected, the approximately diamond-shaped boss of the booster pump is embedded in the groove 4 of the transition plate and connected to the threaded hole of the clutch housing through bolts.

[0046] This structure transfers the difference of clutch housing connection structure to the transition plate, has simple structure, low cost, and only requires simple machining. It can simultaneously meet the requirements of two holes and four holes for connecting the clutch housing to the power pump, and has obvious innovations.
