Embodiment 1

[0025] Such as Figure 1~2 As shown, this embodiment provides a synchronous shift wet hydraulic clutch for automatic transmission, including power input and output components, control execution components and synchronous feedback components; wherein,

[0026] The power input and output assembly includes the clutch hub 13, the outer ring gear B21 and the outer ring gear A22. The clutch hub 13 is used as the clutch main body, and the clutches A and B share one clutch hub 13 . The inner hole of the clutch hub 13 is processed with splines or flat keys for connecting the central power shaft. The outer circle of the clutch hub 13 is processed with splines for connecting and fixing the steel sheet 2 with internal splines. The middle of the outer spline of the clutch hub 13 is processed with a circlip groove, and the stop ring 3 is fitted on the outer spline of the clutch hub 13 through the inner spline, and the stop ring 4 is used to limit the position, so that the clutch hub 13 is...

Abstract

The invention discloses a synchronous gear shifting type wet hydraulic clutch for an automatic gearbox. The synchronous gear shifting type wet hydraulic clutch comprises a power input and output component, a friction pair assembly, a control execution component, a synchronous feedback component and a sealing component. The synchronous gear shifting type wet hydraulic clutch is of an integrated design and integrates four parts of control, execution, cooling and lubrication; the working stability and the transmission efficiency of the clutch are improved through the integrated design; the dailymaintenance cost is reduced; the installation space is saved, and the use method is simpler, more convenient and more flexible. A friction pair is of a wet multi-piece structure formed by alternatelymounting steel and sintered/paper substrates, the specific pressure is high, the friction coefficient is large, the wear coefficient is small, and the heat capacity is high; the characteristics of thefriction pair determine that the size of the clutch is small, and the generated torque is large; the combined structure form can generate very high torque under very small inertia, and maintenance isbasically not needed; the friction pair is made of a metal sintered material, no asbestos component exists, and the environment cannot be polluted; and the ratio of the dynamic friction coefficient to the static friction coefficient of the multi-piece structure is small, meshing balance is achieved, and noise cannot be generated.

Description

technical field [0001] The invention relates to the technical field of clutches, in particular to a synchronous shift wet hydraulic clutch for an automatic transmission. Background technique [0002] Clutches are common components in mechanical transmissions that can disengage or engage the transmission system at any time. The traditional clutch structure design is not reasonable enough, its working stability and transmission efficiency are low, the daily maintenance cost is high, and the installation is inconvenient. Therefore, there is an urgent need for a clutch with high stability and transmission efficiency, low maintenance cost, and a simple and flexible method of use. Contents of the invention [0003] The purpose of the present invention is to provide a synchronous shift wet hydraulic clutch for an automatic transmission, which is used to improve the clutch's anti-disorder ability, stability and transmission efficiency, reduce the development cost of the automatic...
