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

The present application discloses a brake pedal device with a variable pedal ratio, which includes a pedal shaft rotatably disposed in a pedal area plate. The brake pedal is coupled to the pedal shaft. A slider is coupled to the pedal shaft so as to be axially moveable relative to the pedal shaft while being rotatable therewith. The drive unit can move the slide axially in response to the driver's actions. The adjustment rod is fixed to the slider and is arranged obliquely. A drive shaft is coupled to the adjustment lever so as to be movable, and to a dual circuit brake valve to operate the dual circuit brake valve. With the driveshaft engaged to the dual circuit brake valve, the pedal ratio is adjusted as the adjustment rod moves together with the slider during axial movement of the slider.

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.
