(EN) ELECTRIC PARKING BRAKE DRIVING DEVICE AND ELECTRIC PARKING BRAKE DEVICE
(JA) 電動パーキングブレーキ用駆動装置
Abstract
(EN)

PROBLEM TO BE SOLVED: To provide an electric parking brake driving device and an electric parking brake device, capable of reducing a shock sound at a release operation of a parking brake.

SOLUTION: A parking brake actuator generates brake force at a wheel by means of converting rotary motion of a screw member 6 rotated by an electric parking brake driving device D, to a linear motion, transmitting the result to a piston, and pressing a brake pad against a disk rotor by means of the piston. The electric parking brake driving device D includes an electric motor 3, and a speed reduction mechanism 4 for transmitting driving force of the electric motor 3 to the parking brake actuator. The speed reduction mechanism 4 includes a gear body 41, and a planetary gear mechanism YG which is provided within the gear body 41 and to which the driving force of the electric motor 3 is input. A cushion rubber 55 compressible in circumferential direction, is interposed between a ring gear 52 of the planetary gear YG and the gear body 41.

【課題】パーキングブレーキ操作解除時の衝撃音を低減可能な電動パーキングブレーキ用駆動装置および電動パーキングブレーキ装置の提供。
【解決手段】パーキングブレーキアクチュエータは、電動パーキングブレーキ用駆動装置Dによって回転されたスクリュー部材6の回転運動を直進運動に変換してピストンに伝達し、ピストンによってブレーキパッドをディスクロータに押圧することにより車輪に制動力を発生させる。電動パーキングブレーキ用駆動装置Dは、電動モータ3と、電動モータ3の駆動力をパーキングブレーキアクチュエータに伝達する減速機構4を備える。減速機構4は、ギヤボデー41と、ギヤボデー41内に設けられ、電動モータ3の駆動力が入力される遊星歯車機構YGを備える。遊星歯車機構YGのリングギヤ52とギヤボデー41との間には、円周方向に圧縮可能なクッションゴム55が介装されている。
