Problems solved by technology

[0014] However, since the pedal ratio is fixed to a specific value based on the vehicle model, it may not be possible to satisfy the braking feeling depending on the user, and more specifically, cause a limitation on the control feeling (pedal travel and vehicle deceleration) in the braking feeling. massive dissatisfaction

Abstract

A brake pedal apparatus with a variable pedal ratio includes a pedal shaft rotatably disposed in a pedal plate. A brake pedal is coupled to the pedal shaft A slider is coupled to the pedal shaft so as to be axially movable relative to the pedal shaft while being capable of rotating together with the pedal shaft. A drive unit may axially move the slider in accordance with a driver's actuation. An adjusting rod is fixed to the slider and is obliquely disposed. A transmission shaft is coupled to the adjusting rod so as to be movable and is coupled to a dual brake valve to operate the dual brake valve. A pedal ratio is adjusted while the adjusting rod moves together with the slider during axial movement of the slider while the transmission shaft is coupled to the dual brake valve.

Description

technical field [0001] The invention relates to a brake pedal device for a vehicle. More particularly, the present invention relates to a brake pedal device capable of improving a braking feeling felt by a driver through a brake pedal during a braking operation. Background technique [0002] Typically, in heavy commercial vehicles such as trucks and buses, an air brake system with good braking force, less breakdowns, and easy operation is used. [0003] The air brake system uses the air pressure of compressed air to obtain greater braking force with less pedal force. In this braking system, the air compressed by the air compressor is stored in an air tank to which the two inlets of the dual circuit brake valve are connected, and the two outlets of the dual circuit brake valve are connected to the front wheels and the brake chambers of the rear wheels, and the front wheel brake unit and the rear wheel brake unit are connected to the output shaft of each brake chamber.
