Description
本発明は、小型化が可能なストロークシミュレータおよび電動アクチュエータを提供することを目的とする。 An object of this invention is to provide the stroke simulator and electric actuator which can be reduced in size.
上記の課題を解決するために、本発明に係るストロークシミュレータは、ブレーキペダルが連結される入力部材と、前記入力部材の移動に対してバネ力を作用させる反力バネと、前記入力部材と共に移動する摩擦部材と、前記入力部材と共に移動する前記摩擦部材が摺接して摩擦力を発生する摺接部材とを備え、前記摩擦部材は、前記反力バネのバネ力を受けて該バネ力の増大に対して摩擦力を増大させることを特徴とする。
また、本発明に係る電動アクチュエータは、ハウジングと、ブレーキペダルに連結されて前記ハウジング内を変位する入力部材と、前記ブレーキペダルの操作に応じて作動する電動モータと、該電動モータの作動により、マスタシリンダのピストンを推進するアシスト機構と、を有し、前記ハウジング内に設けられ、前記入力部材の変位に伴って該ハウジング内で摺動することにより、前記ブレーキペダルを操作する際の踏力の増大に伴い前記ブレーキペダルに対する反力の増大割合が大きくなり、また、前記ブレーキペダルを解放する際には、前記踏力の減少に対して操作ストロークの減少割合が小さくなるヒステリシス機構を備えていることを特徴とする。
In order to solve the above-described problems, a stroke simulator according to the present invention includes an input member to which a brake pedal is connected, a reaction force spring that applies a spring force to the movement of the input member, and the input simulator moves together with the input member. a friction member, and a sliding member to which the friction member which moves together with the input member to generate a frictional force in sliding contact, before Symbol friction member, of the spring force by receiving a spring force of the reaction force spring The frictional force is increased with respect to the increase.
The electric actuator according to the present invention includes a housing, an input member connected to a brake pedal and displaced in the housing, an electric motor that operates in accordance with an operation of the brake pedal, and an operation of the electric motor An assist mechanism for propelling the piston of the master cylinder, and is provided in the housing, and slides in the housing in accordance with the displacement of the input member, so that the pedaling force when operating the brake pedal is reduced. As the force increases, the rate of increase of the reaction force against the brake pedal increases, and when releasing the brake pedal, a hysteresis mechanism is provided that decreases the rate of decrease of the operation stroke with respect to the decrease of the pedaling force. It is characterized by.
本発明に係るストロークシミュレータおよび電動アクチュエータによれば、小型化が可能になる。 The stroke simulator and the electric actuator according to the present invention can be downsized.
