The motor decelerating clutch has the advantages of unique design, compact structure and small size.

Description

The electric vehicle motor speed-reducing clutch

Technical field

The utility model relates to a kind of driving mechanism of electric vehicle motor, specifically is a kind of electric vehicle motor speed-reducing clutch.

Background technique

Present electric motor car all adopts high-speed electric expreess locomotive to drive, and the fast output torque of high-speed electric expreess locomotive rotating speed is then less, in order to improve output torque and to reduce loss and often adopt retarder and clutch to realize; And when front reduction gear and clutch all be split type, volume is bigger, inner structure is more complicated also, the while cost of production is also higher.

The model utility content

The purpose of this utility model is to provide a kind of electric vehicle motor speed-reducing clutch of integral type, and retarder and clutch organically combine, have be skillfully constructed, compact structure, volume features of smaller.

The utility model is achieved in that

A kind of electric vehicle motor speed-reducing clutch, comprise housing, coupling shaft, planetary pinion and gear positioning plate, three mutual centers of planetary pinion are arranged on a side of gear positioning plate symmetrically, the outside of three planet teeth is meshed with the transmission gear ring of housing body inside, the cover plate of housing is provided with the through hole that can supply driving cog to pass through, be provided with oil sealing in the through hole, driving cog passes this through hole and is meshed with three planetary pinions, housing is built-in with gear oil, it is characterized in that: at described gear positioning plate by apron plate, main body substrate, back backplate stacks gradually and forms, have the through hole of a circle at described main body substrate center, have several clutch breach in through hole edge about the centrosymmetric arc of manhole, the degree of depth of each arc clutch breach is gradually dark or gradually shallow transition, be provided with clutch shaft at manhole, be provided with the clutch roller that matches with this clutch shaft in the clutch indentation, there, the front and back backplate is limited to clutch roller and clutch shaft in manhole and the clutch breach, and the center is provided with three symmetrically and is used for installing planetary gear shaft on main body substrate.

Have a blind hole on the sidewall on one side in that described clutch breach is dark, blind hole is established putting spring and thimble, and the interior roller of thimble and clutch breach contacts.

Be provided with setting sleeve between described manhole and clutch shaft, the position of setting sleeve difference clutch breach is provided with the location needle roller, and the location needle roller contacts with the sidewall of clutch shaft.

Maximum characteristics of the present utility model are that clutch directly is provided with on the gear positioning plate, original two devices that separate of clutch and retarder are organically combined into an integral body, make this install under the prerequisite of concrete retarder and the original fundamental function of clutch, significantly reduce volume, of the present utility modelly be skillfully constructed, reasonable in design, save consumable material when making greatly, reduced cost of production, improved economic benefit.

Embodiment

As Figure 1-3, a kind of electric vehicle motor speed-reducing clutch, comprise housing 1, coupling shaft 2, planetary pinion 3 and gear positioning plate 4, three planetary pinion 3 mutual centers are arranged on a side of gear positioning plate 4 symmetrically, the outside of three planet teeth 3 is meshed with the transmission gear ring 11 of housing 1 body interior, the central position of housing 1 cover plate has central through bore 12, through hole 12 is provided with oil sealing 13, coupling shaft 2 passes this through hole 12 and is meshed with three planetary pinions 3, be filled with gear oil in the housing 1, described gear positioning plate 4 is by apron plate 41, main body substrate 42, back backplate 43 stacks gradually and forms, have a manhole 44 at described main body substrate 42 centers, have several clutch breach 45 in manhole 44 edges about manhole 44 centrosymmetric arcs, the degree of depth of each arc clutch breach 45 is served as reasons gradually dark or gradually shallow transition gradually, described clutch breach 45 is dark to have a blind hole 46 on the sidewall on one side, blind hole 46 is established putting spring and thimble 48, in manhole 44, be provided with clutch shaft 5, between manhole 44 and clutch shaft 5, be provided with setting sleeve 51, the position of setting sleeve 51 difference clutch breach is provided with location needle roller 52, location needle roller 52 contacts with the sidewall of clutch shaft 5, be provided with and this clutch shaft 5 contacted clutch rollers 47 at clutch breach 45 places, roller 47 also contacts with thimble 48, front and

back backplate

41,43 are limited to clutch roller 47 and clutch shaft 5 in manhole 44 and the clutch breach 45.

The utility model is arranged on clutch in the gear positioning plate 4 of retarder dexterously, and it is in aggregates to make that clutch and retarder organically combine; When the utility model uses coupling shaft 2 is linked to each other with the rotor of motor, and clutch shaft 5 generally links to each other with wheel, the motor high speed rotating drives the coupling shaft rotation, the gear ring 11 of coupling shaft and three planetary pinions 3 and housing 1 inboard is formed a train of reduction gears, convert the output of motor high speed low torque to the low speed and large torque defeated gear positioning plate that passes through, can drive clutch roller 47 during 4 rotations of gear positioning plate with respect to clutch shaft 5 motions, after 47 relative clutch shaft 5 motions of clutch roller, can be connected together mutually with clutch shaft 5, thereby make driven by motor clutch shaft 5 rotate together, and then powered vehicle is advanced; And when slowing down to motor, main body substrate 42 can be with respect to clutch shaft 5 counter-rotatings, this moment, clutch shaft 5 can drive clutch rollers 47 toward darker one the connecting and move of clutch breach 45 degree of depth, make clutch roller 47 can compress thimble 46 and spring, make clutch shaft 5 separate with main body substrate 42, this moment, vehicle kept sliding state.

This set of the present utility model has significantly reduced the volume of retarder and clutch, can effectively reduce production costs, sensitivity when spring and thimble can improve deceleration clutch work, setting sleeve can better keep clutch shaft and the higher coaxality of other parts, loss in the time of reducing operation, the delivery efficiency of raising motor.
