Description

この考案は自動車用パワーステアリング装置に関する、特に、モーターの回転力の利用で、ハンドルの回転の助力になれ、運転者の操舵の便利と省力を提供することに関する。 The present invention relates to a power steering apparatus for an automobile, and more particularly, to use the rotational force of a motor to assist the rotation of the steering wheel, and to provide convenience and labor saving for the driver's steering.

従来の自動車用パワーステアリング装置は、一般的に油圧系統であり、ハンドルの回転の助力は、エンジンと連動した油圧ポンプより発生する。 Conventional power steering devices for automobiles are generally a hydraulic system, and the assist of rotation of the steering wheel is generated by a hydraulic pump linked with the engine.

前述従来のパワーステアリング装置は、以下の欠点がある、
１．パワーステアリング装置はエンジンの能率の４％〜６％を消耗する。
２．エンジンの回転の速さより、油圧の効率は不安定になることがある。
３．油圧に使用する作動油の漏れを完全に防ぐことが容易でないこと。
この考案は、以上の問題を解決し、エンジンの能率より消耗しない、装置の効率より安定、作動油漏れの恐れまたくないのパワーステアリング装置の構造を提供することを課題とする。 The above-described conventional power steering device has the following disadvantages:
1. The power steering device consumes 4% to 6% of the engine efficiency.
2. The efficiency of hydraulic pressure may become unstable due to the speed of engine rotation.
3. It is not easy to completely prevent leakage of hydraulic oil used for hydraulic pressure.
An object of the present invention is to solve the above problems, and to provide a structure of a power steering device that is less consumed than the efficiency of the engine, more stable than the efficiency of the device, and less likely to leak hydraulic oil.

そこで、本考案者は従来の技術に見られる欠点に鑑み鋭意研究を重ねた結果、パワーステアリング装置の構造は、ハンドルと連接の回転軸体と、転向センサーと、モーター部と、減速駆動機構と、を備え、前記回転軸体は、モーター部より、動力助力操舵させる。
転向センサーは、ハンドルより回転軸体の回転動作を察知するより、即座に、モーター部を起動し、減速駆動機構を連動させ、減速出力ギアーカヴァーと、回転軸体のボルト歯車部との噛み合い伝動より、運転者のハンドルの操作を、省力させることができる。 Therefore, as a result of intensive research in view of the drawbacks found in the prior art, the present inventor has found that the structure of the power steering device is a rotating shaft body connected to the handle, a turning sensor, a motor unit, a deceleration drive mechanism, The rotating shaft body is driven by power assist from the motor unit.
The turning sensor instantly activates the motor unit by interlocking with the speed reduction drive mechanism by detecting the rotational motion of the rotating shaft body from the handle, and engages the transmission between the deceleration output gear cover and the bolt gear portion of the rotating shaft body. Thus, the operation of the driver's steering wheel can be saved.

前記回転軸体１０は、１端に、軸受１１と、パッキン押さえ１２と、モーター部３０と、を一連の同心円状に設置し、別端に、軸受１３と、パッキン押さえ１４と、減速駆動機構４０と、を一連の同心円状に設置し、回転軸体１０のボルト歯車部１５より、減速駆動機構４０の減速出力ギアーカヴァー４３と、噛み合いで、伝動する。
前記転向センサー２０は、絶縁チューブ２１と、回転軸体１０の適当な位置に、設置し、回転軸体１０の回転を察知するより、モーター部４０の起動と停止の制御を行う。
前記モーター部３０は、１端に、ケーシング３１と、軸受１１と、パッキン押さえ１２と、を一連の同心円状に、回転軸体１０の外周に設置し、モーター回転子３２は、中央に中空軸管３３を挿入固定し、さらに、針状ころ軸受３４と、回転軸１０の外周に備え、モーター回転子３２と回転軸１０を、別々に回転自在となり、中空軸管３３の末端に、ギアー３５を設け、ギアー３５と減速駆動機構４０の遊星歯車モジュール４２と、噛み合いで、伝動する。
前記減速駆動機構４０は、１端に、ケーシング４１と、軸受１３と、パッキン押さえ１４と、を一連の同心円状に、モーター部３０の後に、回転軸体１０の外周に設置し、なかに、複数の遊星歯車モジュール４２を有し、先端の遊星歯車モジュール４２は、モーター回転子３２の中空軸管３３のギアー３５と、噛み合いで、伝動し、末端の遊星歯車モジュール４２は、減速出力ギアーカヴァー４３と、回転軸体１０のボルト歯車部１５と噛み合いで、伝動する。

Referring to the drawings, the power steering device according to the present invention includes a rotating shaft body 10 connected to a handle, a turning sensor 20, a motor unit 30, and a speed reduction driving mechanism 40. The rotating shaft body 10 is a motor. Power steering is performed from the unit 30.
The rotary shaft body 10 has a bearing 11, a packing presser 12, and a motor part 30 installed at one end in a series of concentric circles, and a bearing 13, a packing presser 14, and a reduction drive mechanism at the other end. 40 are installed in a series of concentric circles, and are transmitted from the bolt gear portion 15 of the rotary shaft body 10 in mesh with the reduction output gear cover 43 of the reduction drive mechanism 40.
The turning sensor 20 is installed at an appropriate position of the insulating tube 21 and the rotating shaft body 10 and controls the start and stop of the motor unit 40 by detecting the rotation of the rotating shaft body 10.
The motor unit 30 has a casing 31, a bearing 11, and a packing presser 12 at one end, and is arranged in a series of concentric circles on the outer periphery of the rotary shaft 10, and the motor rotor 32 has a hollow shaft at the center. The tube 33 is inserted and fixed, and further provided on the outer periphery of the needle roller bearing 34 and the rotary shaft 10. The motor rotor 32 and the rotary shaft 10 can be rotated separately, and a gear 35 is provided at the end of the hollow shaft tube 33. The gear 35 and the planetary gear module 42 of the speed reduction drive mechanism 40 are engaged with each other and transmitted.
