Problems solved by technology

However, the working coil is arranged above the active part of the electromagnetic clutch, which requires a large magnetic force and consumes a lot of power when moving the active part of the electromagnetic clutch. On the other hand, in order to place the working coil above the active part of the electromagnetic clutch, the size of the transmission will be get bigger
At the same time, when the electromagnetic clutch works for a long time, it is easy to magnetize the adjacent active parts and move, posing a safety hazard

Embodiment 1

[0062] Such as figure 1 and figure 2 As shown, an anti-electromagnetic interference electric transmission according to the present invention includes a housing 1 , a gear 2 , a shaft 3 and an electric transmission assembly 10 . Shaft 3 includes input shaft 3-1, output shaft 3-2 and intermediate shaft 3-3, input shaft 3-1 and output shaft 3-2 are connected by needle bearing 15, input shaft 3-1, output shaft 3-2 The input shaft gear 2-1, the output shaft gear 2-2 and the intermediate shaft gear 2-3 are fixedly provided with the input shaft gear 2-1 rotating with the shaft 3 by keys respectively on the intermediate shaft 3-3.

[0063] Two sets of electric transmission assemblies 10 are also arranged on the intermediate shaft 3-3. One set of electric transmission assemblies 10 includes a key slider 6 and two shaft gears 4, and the key slider 6 is located between the two shaft gears 4, so that the present An anti-electromagnetic interference electric transmission of the embodime...

Embodiment 2

[0068] Figure 8 It is the schematic diagram of embodiment two. The difference between the second embodiment and the first embodiment mainly lies in that the intermediate shaft 3-3 of the second embodiment is only provided with a set of electric transmission components 10, and one set of electric transmission components 10 includes a key slider 6 and two shaft gears 4, The key slider 6 is located between the two shaft gears 4, so that the anti-electromagnetic interference electric transmission of this embodiment has two gears.

Embodiment 3

[0070] Figure 9 It is the schematic diagram of embodiment three. The difference between the third embodiment and the first embodiment mainly lies in that the intermediate shaft 3-3 of the third embodiment is only provided with a group of electric transmission components 10, and two different intermediate shaft gears 2-3 are added, and the input shaft 3-2 A set of electric transmission assembly 10 is added, and the two rotating shaft gears 4 of the additional electric transmission assembly 10 mesh with the two additional countershaft gears 2-3 on the intermediate shaft 3-3 respectively. In this way, the anti-electromagnetic interference electric transmission of this embodiment has four gears.

Abstract

The invention discloses an electromagnetic interference resisting electric gearbox. The electromagnetic interference resisting electric gearbox comprises a housing, a shaft and an electric speed change component; the electric speed change component comprises a rotating shaft gear, an electric stator, a key slider and an armature, wherein the key slider is arranged on a shaft in a sleeving manner and can move in the axial direction; the armature is fixedly arranged on the key slider; the rotating shaft gear and the key slider are arranged close to each other; the opposite end faces of the rotating shaft gear and the key slider are correspondingly provided with end face teeth and disc surface teeth, wherein the end face teeth and the disc surface teeth can be engaged with each other; the periphery of the rotating shaft gear is provided with peripheral teeth; the electromagnetic interference resisting electric gearbox is characterized in that the electric stator is fixedly arranged on thehousing of the gearbox and is arranged in a manner of being axially opposite to the armature positioned on the key slider; the electric stator always keeps a clearance with the rotating shaft gear and the armature; and excluding the surface, opposite to the electric stator, of the armature, the rest surfaces of the armature are each peripherally provided with a magnesium insulating part. The electromagnetic interference resisting electric gearbox has the characteristics of good electromagnetic interference resistance, stable work, high reliability, good safety, compact structure, small size,relatively low cost, small abrasion, long service life and the like.

Description

[0001] (1) Technical field [0002] The invention relates to the field of electric gearboxes, in particular to an electric gearbox resistant to electromagnetic interference. [0003] (2) Background technology [0004] The gearbox is a gear transmission device that can change the transmission ratio of the output shaft and the input shaft in fixed or step-by-step steps. It is used to change the torque and speed of the engine crankshaft to adapt to different driving conditions such as starting, accelerating, driving, and overcoming various road obstacles. Under different conditions, there are different requirements for driving wheel traction and vehicle speed. Existing new energy vehicle transmissions, such as hydraulic automatic transmission (AT), continuously variable transmission (CVT) and electronically controlled mechanical automatic transmission (AMT), etc., mostly adopt technical routes improved on the basis of traditional internal combustion engine vehicle transmissions ....
