<P>PROBLEM TO BE SOLVED: To reduce a space by integrating a transmission and a motor as a single unit and reduce the number of motors of an electric vehicle by half, in a motor apparatus with a transmission wherein a cavity is formed inside a motor rotor and a transmission mechanism is assembled by hanging it over right and left motor flanges from the cavity. <P>SOLUTION: A transmission is disposed by hanging it over motor flanges from a cavity formed in a motor rotor. Rotation of the motor is divided to right and left by a differential device and its output torque is increased by a speed reducer to reduce the number of motors assembled right and left individually by half. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

本発明は、モーター回転変速機構をモーターに内蔵する構造に関するものである。  The present invention relates to a structure in which a motor rotation transmission mechanism is built in a motor.

本発明は、デフ装置とモーターローターを一列配置し左右車輪に回転動力を振分け伝達する装置に関するものである。
モーター及び回転変速を要する分野特に、車両輸送機分野、巻取り機械分野、生産設備に利用される。The present invention relates to a device that arranges a differential device and a motor rotor in a row and distributes and transmits rotational power to left and right wheels.
It is used in the fields that require motors and rotational shifts, particularly in the field of vehicle transport equipment, the field of winding machines, and production equipment.

従来の増速機、減速機、デフ装置、モーターはそれぞれ独立して製造され連結使用されていて占有容積が大きい為、もっと縮小したい要望に応える。Conventional gearboxes, reducers, differential devices, and motors are manufactured and used independently and have a large occupied volume, so they meet the demands for further reduction.

電気自動車の駆動源として使用されているモーターは、インホイルモーター型でタイヤホイル毎に独立して構築されている。コスト高の欠点がある。  The motor used as the drive source of the electric vehicle is an in-wheel motor type and is constructed independently for each tire wheel. There is a disadvantage of high cost.

またモーター単独、別配置の場合アクスルシャフトに対し２軸の直角配置か並列配置で占有容積が大きくなる欠点がある。  Further, in the case of a single motor or a separate arrangement, there is a disadvantage that the occupied volume becomes large when the two axes are arranged at right angles to the axle shaft or arranged in parallel.

解決しようとする問題点は、モーターと変速機が独立していた物を合体し省容積化する点にある。  The problem to be solved is that the motor and the transmission are combined to save the volume.

解決しようとする問題点は、ホイル個々に内蔵されてるモーターを半減させる点にある。  The problem to be solved is to halve the motor built in each foil.

モーターローターに空洞を設け、空洞からモーターフランジに掛けて変速機構を組込むことで解決する。  The problem is solved by providing a cavity in the motor rotor and installing the speed change mechanism from the cavity to the motor flange.

前述モーターのローターを貫通穴とし、デフ装置とモーターを組み合せて、アクスルシャフトを中空穴を貫通して配置組付けることで解決する。  The problem is solved by using the motor rotor as a through hole, combining the differential device and the motor, and arranging the axle shaft through the hollow hole.

本発明は、ギヤドモーター等の省容積化が図れ軽量化、低コスト化に高い効果が得られる。  According to the present invention, the volume of a geared motor or the like can be reduced, and a high effect can be obtained in terms of weight reduction and cost reduction.

本発明は、電動車両の左右のインホイルモーターを半減でき、ばね下荷重の低減等にも高い効果が得られる。  The present invention can halve the left and right in-foil motors of an electric vehicle, and can achieve a high effect in reducing unsprung loads.

モーターのローターの内部に空洞部を設け、変速機構を組み込むことで省スペース化が図れ、モーターの利用範囲が更に拡大するとともに省スペースを実現した。
内蔵される変速機構は平歯車列、傘歯車列、ハスバ歯車列いずれも組込み可能である。Space was saved by providing a cavity inside the rotor of the motor and incorporating a speed change mechanism, further expanding the range of use of the motor and realizing space saving.
The built-in transmission mechanism can incorporate any of a spur gear train, a bevel gear train, and a helical gear train.

前述の空洞部からモーターフランジに掛けてデフ歯車装置を、組み込みモーターの両側に出力軸を、出すようにして実現した。  The differential gear unit was hung from the cavity to the motor flange, and the output shafts were put out on both sides of the built-in motor.

図１は、本発明装置の１実施例の断面図であって、遊星歯車列の解説図でロータ１ａに連結固定された太陽歯車２ａが回転第一遊星歯車２ｂに伝達されるフランジ４ａに固定された内歯歯車２ｃと噛合って自転しつつ公転し第一回転腕２ｄへと伝達される、出力腕の中心部に２段目の第二太陽歯車２ｅが固定され同様に第二遊星歯車２ｆから第二回転腕２ｇへと伝達され軸受けで固定された出力軸２ｈをへて外部被動体へ伝達される。  FIG. 1 is a cross-sectional view of an embodiment of the device of the present invention, in which a sun gear 2a connected and fixed to a rotor 1a is fixed to a flange 4a transmitted to a rotating first planetary gear 2b. The second sun gear 2e at the second stage is fixed to the center of the output arm, and the second planetary gear is similarly fixed. The output shaft 2h is transmitted from 2f to the second rotating arm 2g and fixed by the bearing, and is transmitted to the external driven body.

図２は、デフ装置を組み込んだ実施例である。
ローター１ｃに設けられた空洞部１ｅにデフケース５ａが固定され回転すると、デフケースに取り付けられたピン５ｃが同時に回転する、そのピン５ｃに回転可能に傘歯車５ｂ１、５ｂ２が装着され左右に振り分ける為の傘歯車５ｄ１、５ｄ２が噛合って取り付けられている、それぞれ軸を介し左右に設けられた減速装置６ａ，６ｂへと伝達され被駆動体へ伝達される。FIG. 2 shows an embodiment incorporating a differential device.
When the differential case 5a is fixed and rotated in the hollow portion 1e provided in the rotor 1c, the pin 5c attached to the differential case rotates at the same time. The bevel gears 5d1 and 5d2 are engaged with each other and are respectively transmitted to the reduction gears 6a and 6b provided on the left and right via the shafts and transmitted to the driven body.

デフ装置は、遊星歯車方式、傘歯車方式、摩擦車方式のいずれも同様の動作が可能である。  The differential device can perform the same operation in any of the planetary gear system, the bevel gear system, and the friction wheel system.

図６はの実施例は、遊星歯車方式デフ装置をモーターローターの内部に配置し、左右に減速機を配置トルク増幅した構造である。出力の方法は１段  The embodiment shown in FIG. 6 has a structure in which a planetary gear type differential device is arranged inside a motor rotor, and reduction gears are arranged on the left and right to amplify torque. The output method is one stage

図７の実施例は、デフ装置を小径の中空軸モーターを利用しモーターの外部に配置し構造である。  The embodiment of FIG. 7 has a structure in which the differential device is arranged outside the motor using a small-diameter hollow shaft motor.

出力フランジに等速ジョイントを一体化した、又遠心クラッチ、ワンウエィクラッチを併用して性能向上も出来る  A constant velocity joint is integrated with the output flange, and performance can be improved by using a centrifugal clutch and a one-way clutch.
