Description
【
Technical field
】
The present invention relates to the control system technical field of vehicle, especially relate to a kind of electric automobile CVT clutch.
[background technology]
nullKnown，The maximum problem that current CVT exists is initiative taper dish and works asynchronous from mantle dish，Cause in the work of cone dish and skid and dally，And skidding and dally in CVT works is a most fatal problem，This phenomenon is the biggest to the abrasion of cone dish，The biggest to the aging effects of belt，Some designer thinks that electronic CVT there is no need to use clutch，Actually this is not so，The accuracy that cone dish is run by clutch is very necessary，Because being frequently encountered some special circumstances in actual motion，Such as emergency brake、The situation of the improper travelings such as snowfield brake or wheel limit skidding，At this time it is accomplished by the device in case of emergency making main shaft separate with gear-box，In the application by its folding of programme-control，Riding stability and the safety of vehicle can well be improved，The performance of car load is improved.
[summary of the invention]
In order to overcome the deficiency in background technology, the invention discloses electric motor car CVT speed change box clutch, the present invention puts electromagnetism pressure ring and output shaft tabletting by setting up separately on power shaft and output shaft, and electric magnet is set on electromagnetism pressure ring, input splined shaft is set on output shaft tabletting, on input splined shaft, input shaft clutch sheet is set, reaches the purpose of traffic safety when improper traveling with this.
In order to realize described goal of the invention, the present invention adopts the following technical scheme that
A kind of electric automobile CVT clutch, including power shaft, output shaft, electromagnetism pressure ring, electric magnet, gland, shell, disc spring, upper pressure clutch disc, input shaft clutch sheet, output shaft tabletting and input splined shaft, power shaft is corresponding with the axle center of output shaft, power shaft is provided with electromagnetism pressure ring and gland, electromagnetism pressure ring is provided with electric magnet, described output shaft is provided with output shaft tabletting and input splined shaft, input splined shaft is provided with input shaft clutch sheet, output shaft tabletting is provided with shell, shell is connected with gland, it is provided with disc spring in the enclosure, disc spring is provided with pressure clutch disc, upper pressure clutch disc is corresponding with input shaft clutch sheet.
Described input splined shaft and shell are all enclosed within power shaft, and input splined shaft is arranged in the enclosure.
Described disc spring is camber structure, and one end of disc spring is connected with the inwall of shell, and the other end of disc spring is connected with upper pressure clutch disc.
Described electromagnet sleeve is on electromagnetism pressure ring.
Owing to have employed technique scheme, there is advantages that
Change speed gear box CVT clutch of the present invention, including CPU, ECU, signaling module, Battery converter, CPU supply module, terminal debugging interface, buncher and motor drive ic, electromagnetism pressure ring and output shaft tabletting is put by setting up separately on power shaft and output shaft, and electric magnet is set on electromagnetism pressure ring, input splined shaft is set on output shaft tabletting, on input splined shaft, input shaft clutch sheet is set, reaches the purpose of traffic safety when improper traveling with this；The present invention is practical, operate the simplest, at extreme geographical environment, precipitous big slope, sleet sky emergency brake or abrupt slope hill start when, after have employed CVT electromagnetic clutch, after emergency brake, by the separation of clutch, cone dish can be made to continue to rotate, until cone dish returns to large speed ratio, thus ready for starting to walk next time, greatly improve the safety of driving.
[accompanying drawing explanation]
Fig. 1 is the block schematic illustration of the present invention；
In figure: 1, power shaft；2, electromagnetism pressure ring；3, electric magnet；4, gland；5, shell；6, disc spring；7, upper pressure clutch disc；8, input shaft clutch sheet；9, output shaft tabletting；10, output shaft；11, input splined shaft.
[detailed description of the invention]
The explanation present invention that can be detailed by the following examples, the open purpose of the present invention is intended to protect all technological improvements in the scope of the invention.
In conjunction with a kind of electric automobile CVT clutch described in accompanying drawing 1, including power shaft 1, output shaft 10, electromagnetism pressure ring 2, electric magnet 3, gland 4, shell 5, disc spring 6, upper pressure clutch disc 7, input shaft clutch sheet 8, output shaft tabletting 9 and input splined shaft 11, power shaft 1 is corresponding with the axle center of output shaft 10, power shaft 1 is provided with electromagnetism pressure ring 2 and gland 4, electromagnetism pressure ring 2 is provided with electric magnet 3, described output shaft 10 is provided with output shaft tabletting 9 and input splined shaft 11, input splined shaft 11 is provided with input shaft clutch sheet 8, output shaft tabletting 9 is provided with shell 5, shell 5 is connected with gland 4, disc spring 6 it is provided with in shell 5, disc spring 6 is provided with pressure clutch disc 7, upper pressure clutch disc 7 is corresponding with input shaft clutch sheet 8；Described input splined shaft 11 and shell 5 are all enclosed within power shaft 1, and input splined shaft 11 is arranged in shell 5；Described disc spring 6 is camber structure, and one end of disc spring 6 is connected with the inwall of shell 5, and the other end of disc spring 6 is connected with upper pressure clutch disc 7；Described electric magnet 3 is enclosed within electromagnetism pressure ring 2.
nullImplement a kind of electric automobile CVT clutch of the present invention，Work when，First pass through power shaft 1 to transfer power to input on splined shaft 11，Then it is delivered on input clutch plate 7 by input splined shaft 11，This time，By powering to electric magnet 3，Electric magnet 3 drives electromagnetism pressure ring 2 to move to the right，Electromagnetism pressure ring 2 drives gland 4 to be operated again，Pressure clutch disc 7 is unclamped to the left，So input shaft clutch sheet 8 and output shaft 10 is just separated，So that the moment transmission of power shaft 1 and output shaft 10 disconnects，Thus reach CVT variator operating alone，The impact slowed down of stopping will not be received，So at extreme geographical environment，Such as precipitous big slope、The when of sleet sky emergency brake or abrupt slope hill start，After have employed CVT electromagnetic clutch，After emergency brake，By the separation of clutch，Cone dish can be made to continue to rotate，Until cone dish returns to large speed ratio，Thus it is ready for starting to walk next time.
Part not in the detailed description of the invention is prior art.
