Description

A kind of electric automobile CVT clutch

【Technical field】

This utility model is related to the control system technical field of vehicle, especially relates to a kind of electric automobile CVT clutch Device.

【Background technology】

Known, the problem of the maximum that current CVT exists is initiative taper disk and works from mantle disk asynchronous, causes to bore Skid in disk work and dally, and skidding and dallying in CVT work is a problem the most fatal, the mill to cone disk for this phenomenon Damage very big, very big to the aging effects of belt, some designers think that electronic CVT there is no need to use clutch, its Real not so the accuracy that clutch runs to cone disk is very necessary, because it is special to be frequently encountered some in actual motion Different situation, the such as situation of the improper traveling such as the brake of emergency brake, snowfield or the skidding of wheel side, at this time it is accomplished by urgent feelings Make main shaft and the detached device of gear-box under condition, lean on its folding of programme-control in the application, can be very good to improve vehicle Riding stability and safety, improve to the performance of car load.

【Utility model content】

In order to overcome the shortcomings of in background technology, the utility model discloses electric motor car CVT speed change box clutch, this practicality New put electromagnetism pressure ring and output shaft tabletting by setting up separately on input shaft and output shaft, and electromagnetism is arranged on electromagnetism pressure ring Ferrum, setting input splined shaft on output shaft tabletting, input splined shaft arranges input shaft clutch piece, to be reached in anon-normal with this The purpose of traffic safety when often travelling.

In order to realize described utility model purpose, this utility model adopts the following technical scheme that：

A kind of electric automobile CVT clutch, including input shaft, output shaft, electromagnetism pressure ring, electric magnet, gland, shell, Disc spring, upper pressure clutch disc, input shaft clutch piece, output shaft tabletting and input splined shaft, the axle center of input shaft and output shaft Corresponding, electromagnetism pressure ring and gland are provided with input shaft, electromagnetism pressure ring is provided with electric magnet, and described output shaft is provided with output Axial compression piece and input splined shaft, input splined shaft is provided with input shaft clutch piece, and output shaft tabletting is provided with shell, shell with Gland is connected, and is provided with disc spring in inside the shell, and disc spring is provided with pressure clutch disc, upper pressure clutch disc and input shaft clutch Piece is corresponding.

Described input splined shaft and shell are all enclosed within input shaft, and input splined shaft is arranged on inside the shell.

Described disc spring is camber structure, and one end of disc spring is connected with the inwall of shell, the other end of disc spring and on press from Clutch piece is connected.

Described electromagnet sleeve is on electromagnetism pressure ring.

Due to employing technique scheme, this utility model has the advantages that：

Change speed gear box CVT clutch described in the utility model, supplies including CPU, ECU, signaling module, Battery converter, CPU Electric module, terminal debugging interface, buncher and motor drive ic, put electromagnetism pressure by setting up separately on input shaft and output shaft Ring and output shaft tabletting, and electric magnet is set on electromagnetism pressure ring, on output shaft tabletting, setting input splined shaft, inputs splined shaft Upper setting input shaft clutch piece, to reach the purpose of the traffic safety in improper traveling with this；This utility model practicality By force, operate very simple, in extreme geographical environment, on precipitous big slope, sleet sky emergency brake or abrupt slope half When hill start step, after employing CVT electromagnetic clutch, after emergency brake, by the separation of clutch, cone disk can be made to continue Continuous rotation, until cone disk returns to large speed ratio, thus ready for starting to walk next time, greatly improve the safety of driving.

【Brief description】

Fig. 1 is block schematic illustration of the present utility model；

In figure：1st, input shaft；2nd, electromagnetism pressure ring；3rd, electric magnet；4th, gland；5th, shell；6th, disc spring；7th, upper pressure clutch Piece；8th, input shaft clutch piece；9th, output shaft tabletting；10th, output shaft；11st, input splined shaft.

【Specific embodiment】

Explanation this utility model that can be detailed by the following examples, open the purpose of this utility model is intended to protect All technological improvements in the range of this utility model.

In conjunction with a kind of electric automobile CVT clutch described in accompanying drawing 1, including input shaft 1, output shaft 10, electromagnetism pressure ring 2nd, electric magnet 3, gland 4, shell 5, disc spring 6, upper pressure clutch disc 7, input shaft clutch piece 8, output shaft tabletting 9 and input flower Key axle 11, input shaft 1 is corresponding with the axle center of output shaft 10, is provided with electromagnetism pressure ring 2 and gland 4, electromagnetism pressure ring on input shaft 1 2 are provided with electric magnet 3, and described output shaft 10 is provided with output shaft tabletting 9 and input splined shaft 11, and input splined shaft 11 is provided with Input shaft clutch piece 8, output shaft tabletting 9 is provided with shell 5, and shell 5 is connected with gland 4, is provided with disc spring 6 in shell 5, Disc spring 6 is provided with pressure clutch disc 7, and upper pressure clutch disc 7 is corresponding with input shaft clutch piece 8；Described input splined shaft 11 and shell 5 be all enclosed within input shaft 1, input splined shaft 11 be arranged in shell 5；Described disc spring 6 is camber structure, disc spring 6 One end be connected with the inwall of shell 5, the other end of disc spring 6 with upper pressure clutch disc 7 be connected；Described electric magnet 3 is enclosed within On electromagnetism pressure ring 2.

Implement a kind of electric automobile CVT clutch described in the utility model, when work, first pass through input shaft 1 transfer power to input splined shaft 11 on, then pass through input splined shaft 11 be delivered on input clutch plate 7, this when Wait, by powering to electric magnet 3, electric magnet 3 drives electromagnetism pressure ring 2 to be moved to the right, and electromagnetism pressure ring 2 drives gland 4 to enter again So that upper pressure clutch disc 7 is unclamped to the left, such input shaft clutch piece 8 and output shaft 10 are just separated for row work, thus Input shaft 1 and the moment transmission of output shaft 10 are disconnected, thus reaching CVT variator operating alone, parking will not be received and subtract The impact of speed, so in extreme geographical environment, such as precipitous big slope, sleet sky emergency brake or abrupt slope hill start when Wait, after employing CVT electromagnetic clutch, after emergency brake, by the separation of clutch, cone disk can be made to continue rotation, directly Return to large speed ratio to cone disk, thus ready for starting to walk next time.

The non-detailed portion of this utility model is prior art.
