Description
Technical field
This utility model relates to Clutch Technology field, relates in particular to a kind of built-in multi-disc wet clutch.
Background technology
Clutch is arranged between electromotor and variator, is the total member being directly associated with electromotor in drive system.Realize between uniting for reasonable match cutting off and transmission power.Wherein, adopt fluid cooling, be called wet clutch, there is power transmission smooth soft, the feature that service life is longer.Traditional wet clutch volume is comparatively huge, requires higher to gear-box mounting design.And it is not suitable for the occasion of frequent high speed dynamic engagement.How overcoming the problems referred to above is the direction that those skilled in the art need research.
Utility model content
For solving the problems referred to above, this utility model provides a kind of built-in multi-disc wet clutch.
Concrete technical scheme of the present utility model is as follows:
A kind of built-in multi-disc wet clutch, including input gear, inputs splined shaft, friction pair, external tooth housing, oil cylinder housing, output shaft, piston and disc spring；Described friction pair includes steel disc and the scraps of paper；Described input gear connects input splined shaft, and described input splined shaft is meshed with the scraps of paper；Described output shaft, oil cylinder housing, external tooth case weld are integrated；Described external tooth housing is meshed with steel disc；Being provided with oil cylinder and power oil duct in described cylinder shell body, described power oil duct turns on oil cylinder, is used for injecting hydraulic oil in oil cylinder；Described piston one end is positioned at oil cylinder, the other end is connected with disc spring, friction pair；When power oil duct injects hydraulic oil in oil cylinder, piston is promoted compression disc spring, compressing steel disc and the scraps of paper by oil pressure, makes steel disc and the scraps of paper are meshed into one by frictional force；When hydraulic oil unimplanted in oil cylinder, piston is promoted reset by disc spring, is made steel disc separate with the scraps of paper.
By adopting this technical scheme: in practice, control hydraulic oil and entered in oil cylinder by oil duct, piston overcomes the active force of disc spring to move under hydraulic action, steel disc and the scraps of paper are made to be meshed into one by frictional force, power is delivered to external tooth housing through input gear, input splined shaft, friction pair successively, then is delivered to output shaft by external tooth housing and realizes the transmission of power.And when, under not controlling hydraulic pressure oil condition, piston resets at the move under influence of disc spring, makes the scraps of paper and steel disc lose frictional force and separate, interrupt the transmission of power.
Preferably, in above-mentioned built-in multi-disc wet clutch: be additionally provided with cooling oil duct in described cylinder shell body；Connection slip ring on described piston；When piston is promoted reset by disc spring, the outlet of described slip ring blocking cooling oil duct；When piston is by when being promoted by oil pressure, described slip ring opens the outlet of cooling oil duct, makes described cooling oil duct be conducted to friction pair.
By adopting this technical scheme: when steel disc and the scraps of paper are meshed into one by frictional force, slip ring synchronizes, and slip ring opens the outlet of cooling oil duct, makes described cooling oil duct be conducted to friction pair, and friction pair provides fluid cooling.And when not controlling to inject hydraulic oil in oil cylinder, the outlet of slip ring blocking cooling oil duct；Stop friction pair being supplied cooling oil.Thus, utilize the product minimizing in service life that cooling oil prevents friction pair frequent operation from causing, meet the demand that this product can carry out using under the occasion of frequent high speed dynamic engagement.
Compared with prior art, this utility model compact conformation, effectively reduce gear-box volume, save installing space, there is higher stability, it is adaptable to the frequently occasion of high speed dynamic engagement.

Detailed description of the invention
In order to be illustrated more clearly that the technical solution of the utility model, below in conjunction with accompanying drawing, this utility model is further described.
Embodiment 1 of the present utility model as shown in Figure 1:
A kind of built-in multi-disc wet clutch: include input gear 1, inputs splined shaft 2, friction pair, external tooth housing 4, oil cylinder housing 5, output shaft 6, piston 7, disc spring 8 and slip ring 9.Wherein, described friction pair includes steel disc 31 and the scraps of paper 32；Described input gear 1 connects input splined shaft 2, and described input splined shaft 2 is meshed with the scraps of paper 32；Described output shaft 6, oil cylinder housing 5, external tooth housing 4 are welded as a whole；Described external tooth housing 4 is meshed with steel disc 31.Be provided with oil cylinder 51, power oil duct 52 and cooling oil duct 53 in described oil cylinder housing 5, described power oil duct 52 turn on oil cylinder 51, in oil cylinder 51 inject hydraulic oil；Described piston 7 one end is positioned at oil cylinder 51, the other end is connected with disc spring 8, friction pair and slip ring 9.
In practice: when power oil duct 52 injects hydraulic oil in oil cylinder 51, piston 7 is promoted compression disc spring 8, simultaneously compressing steel disc 31 and the scraps of paper 32 by oil pressure, makes steel disc 31 and the scraps of paper 32 are meshed into one by frictional force；Power is delivered to external tooth housing 4 through input gear 1, input splined shaft 2, friction pair successively, then is delivered to output shaft 6 by external tooth housing 4 and realizes the transmission of power.Meanwhile, described slip ring 9 opens the outlet of cooling oil duct 53, makes described cooling oil duct 53 be conducted to friction pair 3, and friction pair provides fluid cooling.And when not controlling to inject hydraulic oil in oil cylinder 51, piston 7 is promoted reset by disc spring 8, makes steel disc 31 and the scraps of paper 32 separate.Make interruption of power transmission.Meanwhile, described slip ring 9 blocks the outlet of cooling oil duct 53；Stop friction pair being supplied cooling oil.
The above; it is only specific embodiment of the utility model; but protection domain of the present utility model is not limited thereto; any those skilled in the art is in technical scope disclosed in this utility model; the change that can readily occur in or replacement, all should be encompassed within protection domain of the present utility model.Protection domain of the present utility model is as the criterion with the protection domain of claims.
