Problems solved by technology

The centrifugal lubrication method cannot achieve selective lubrication, and the lubricating oil supply is the same when the clutch is working and not working, which reduces the efficiency of the transmission; although the forced lubrication method can achieve selective lubrication through the controller, it needs to use a control valve and a separate lubricating oil circuit , increasing the cost more

Embodiment Construction

[0027] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0028] see Figure 1-Figure 6 , a clutch lubricating structure, including the back plate 10 and the piston housing 2 connected to the transmission housing 8 by bolts 11, and the first pair plates 13 are alternately arranged in the installation space formed by the back plate 10 and the piston housing 2 And the friction plate 12, the outer side of the friction plate 12 at the end is provided with a second dual plate 16, the first dual plate external teeth 21 of the first dual plate 13 and the second dual plate external teeth 20 of the second dual plate 16 are connected with the piston shell The internal teeth of the body 2 are mated and connected, and the diameter of the second dual plate 16 is greater than the diameter of the first dual plate 13 and the friction plate 12. A return spring 9 is arranged between the second dual plate 16 and the back plate 10, and the fric...

Abstract

The invention discloses a clutch lubrication structure and method. The clutch lubrication structure comprises a backboard connected to a transmission housing and a piston housing. The installation space formed by the backboard and the piston housing is internally provided with first dual discs and friction plates alternately. A second dual disc is arranged on the outer side of the friction plate located at the tail end. The piston housing is internally provided with a piston used for pushing the second dual disc. A piston oil duct of the piston communicates with an oil inlet channel. The piston is internally provided with a piston body which is matched with the piston oil duct. A back base used for pushing the second dual disc is arranged on the rear side of the piston body. A compression spring is arranged between the piston body and the back base. By means of the clutch lubrication structure and method, selective lubrication of a clutch can be realized, in other words, lubricating oil is available at the engaged stage of the clutch; however, no lubricating oil exists when the clutch does not work or after work of the clutch is completed; and therefore the dragging loss of the clutch can be reduced, design flow of an oil pump is lowered, and the transmission efficiency is improved.

Description

technical field [0001] The invention belongs to the field of clutches, and in particular relates to a clutch lubricating structure and method. Background technique [0002] The main reasons that affect the life of the clutch are wear and ablation. Therefore, sufficient lubrication is essential, and the continuous supply of lubricating oil consumes energy, especially when the clutch is not working, a large amount of lubricating oil causes friction between the friction plate and the counter plate Higher resistance, known as drag loss, reduces the overall efficiency of the transmission. In the initial stage of the clutch combination, the friction plate and the pair plate of the friction plate box rub against each other intensely and generate a lot of heat, but basically no friction and heat are generated after the combination is completed. [0003] However, the commonly used lubrication methods include centrifugal lubrication and forced lubrication. The centrifugal lubricatio...
