Abstract

The present invention relates to a braking device for an automobile configured to brake a moving automobile through a magnetic flux coupling method. In the present invention, a disc (10) is coupled to a wheel hub (1) to which an automobile wheel is coupled, and a first magnetic member (20) is installed on the disc. The first magnetic member (20) is equipped with a permanent magnet or an electromagnet. Additionally, a second magnetic member (30) is provided adjacent to the disc. The second magnetic member (30) is equipped with an electromagnet, and the first or second magnetic member is driven by a control device (40) when the driver operates the brake pedal or when it is necessary to reduce the speed of the automobile or stop it. The second magnetic member (30) is duty-driven by the control device. The control device (40) provides appropriate braking force to the vehicle by adjusting the amount of magnetic flux generated by the second magnetic member (30) by increasing or decreasing the attractive force between the first magnetic member (20) and the second magnetic member (30).

Description

Braking device of vehicle The present invention relates to a braking device for an automobile, and more particularly to a braking device for an automobile configured to brake a moving automobile through a magnetic flux coupling method. Generally, an automobile is equipped with a power generation device, such as an engine, and is configured to move by rotating wheels using the power generated by this device. Basically, an automobile is equipped with a power generation device, such as an engine, that generates power for the movement of the automobile, and a braking device to restrain or limit the movement of the automobile. Automotive braking systems primarily utilize disc or drum brake systems. These are configured to limit or stop the rotation of the vehicle's wheels by utilizing physical contact—specifically friction—between a disc and a pad, or a drum and a lining. In this process, the disc pad and lining operate hydraulically or electronically in response to the driver's manipulation of the brake pedal. FIGS. 1 and 2 are configuration diagrams showing the configuration of a braking device according to a disc type. FIG. 1 is a perspective view showing the schematic coupling relationship between a brake disc (2) and a caliper (3), and FIG. 2 is a side view showing the schematic configuration of the side parts. In the drawings, reference numeral 1 is a wheel hub. A car wheel is coupled to the wheel hub (1) through a fastening member (1a). Additionally, a brake disc (2) is coupled to the wheel hub (1) and rotates together with the wheel hub (1). A brake caliper (3) is installed on one side of the disc (2). A brake pad (3a) is provided on the inner side of the body of the caliper (3). Although not specifically shown in the drawings, the brake pad (3a) is operated electronically or hydraulically. When the driver operates the brake pedal, the brake pad (3a) presses against the surface of the disc (2) in response to the amount of operation, and the rotational force of the disc (2) is reduced by the frictional force between the disc (2) and the pad (3a). Since automobile braking systems are configured to utilize friction, wear occurs on the braking components responsible for generating braking force, namely pads or linings. Consequently, this results in the disadvantage of requiring the inspection and replacement of these braking components. Furthermore, conventional braking systems may experience problems such as reduced braking performance due to abnormal phenomena like vapor lock caused by thermal energy resulting from friction between braking components. Recently, braking devices capable of providing braking force to an automobile in a non-contact manner, rather than through physical contact between braking members, have been introduced. For example, Korean Registered Patent No. 10-2487352 (Title: Electromagnetic Braking Device for Automobiles) and Published Patent No. 10-2013-0097401 (Title: Braking Device Having a Magnetic Base, Braking System Using the Same, and Rail Bike) disclose devices capable of providing braking force to an automobile using a magnetic method.
