Method and apparatus for electromagnetically braking a motor

An electromagnetic braking system and method is provided for selectively braking a motor using an electromagnetic brake having an electromagnet, a permanent magnet, a rotor assembly, and a brake pad. The brake assembly applies when the electromagnet is de-energized and releases when the electromagnet is energized. When applied the permanent magnet moves the brake pad into frictional engagement with a housing, and when released the electromagnet cancels the flux of the permanent magnet to allow a leaf spring to move the brake pad away from the housing. A controller has a DC/DC converter for converting a main bus voltage to a lower braking voltage based on certain parameters. The converter utilizes pulse-width modulation (PWM) to regulate the braking voltage. A calibrated gap is defined between the brake pad and permanent magnet when the brake assembly is released, and may be dynamically modified via the controller.

본 발명은 차량용 브레이크 부스터에 관한 것으로, 공기 유입 시 발생되는 소음을 줄이며 전체적인 조립 작업성을 향상시킬 수 있도록 밸브본체내에서 입력축과 포펫밸브를 탄성 지지하는 탄지부재를 개선한 것이다. The present invention relates to a brake booster for a vehicle, and improves the support member elastically supporting the input shaft and the poppet valve in the valve body so as to reduce the noise generated when the air inflow and improve the overall assembly workability. 본 발명에 따른 차량용 브레이크 부스터에 의하면, 밸브본체(60)내에 입력축(40)과 포펫밸브(64)를 탄성 지지하기 위한 탄지부재(90)가 설치되는데, 이것은 입력축(40)을 지지하기 위한 원통형상의 제1코일스프링부(91)와 포펫밸브(64)를 지지하기 위한 제2코일스프링부(92)가 일체로 마련된다. 이에 따라 하나의 탄지부재(90)를 통해 포펫밸브(64)와 입력축(40)이 동시에 지지되기 때문에, 이의 조립 작업성이 향상되며 전체적인 제조비용을 절감할 수 있다. 또한, 원통형상의 탄지부재(90) 내부공간을 통해 공기 흡입이 원활하게 이루어짐으로써, 브레이크 부스터의 전체적인 작동소음이 줄어드는 이점이 있다. According to the brake booster for a vehicle according to the present invention, a support member 90 for elastically supporting the input shaft 40 and the poppet valve 64 is installed in the valve body 60, which is cylindrical for supporting the input shaft 40. The first coil spring portion 91 and the second coil spring portion 92 for supporting the poppet valve 64 are integrally provided. Accordingly, since the poppet valve 64 and the input shaft 40 are simultaneously supported by the one finger member 90, its assembly workability can be improved and the overall manufacturing cost can be reduced. In addition, since the air intake is made smoothly through the inner space of the cylindrical support member 90, there is an advantage that the overall operating noise of the brake booster is reduced.

Brake mechanism and a method for controlling the power gain

The present invention concerns a brake mechanism of a disc brake received in a caliper (16) and a method for controlling the force amplification for the brake mechanism. The brake mechanism comprises a lever (26, 31) actuated by a brake actuator. The lever is acting on a cross bar (34, 37) by means of an intermediate part (27). The lever (26, 31) and the intermediate part (27) have a line of contact moving along a circular arc during an application stroke of the brake mechanism. The cross bar (34, 37) of the brake mechanism is closely guided and is only moveable in the thrust direction and in the tangential direction of the brake disc. The force amplification of the brake mechanism is adapted to the force characteristics of the brake actuator.

Method and apparatus for reducing rolling motion of a trailer provided with an over-run braking system

Electro-hydraulic braking system for automotive vehicle trailers with an over-run brake

The electro-hydraulic braking system for trailers fitted with a tow bar (1) with overrun device (12) has an isolation device (13) fitted between the first brake pressure generator (9) and the wheel brakes (7), by which means the hydraulic connection between the first brake pressure generator (9) and the wheel brakes (7) is blocked during driving operation, while a second brake pressure generator (15) is hydraulically connected to the wheel brakes (7). Furthermore, the braking system consists of a pressure sensor, which detects the pressure of the first brake pressure generator (9). The control unit (11) works in such a way that the operation of the second brake pressure generator (15) is initiated in dependence of the measured pressure of the first brake pressure generator (9). The second brake pressure generator (15) is connected to a high- pressure storage device and is capable of quickly building up the necessary brake pressure and does not have to be located near the overrun device, but can be installed close to the wheel brake (7), which leads to a quicker and more direct braking due to the lack of hydraulic damping.
