Description

자전거용 유압식 제동 및 기동장치{Hydraulic Braking and Driving for Bicycle}Hydraulic Braking and Driving for Bicycles

자전거를 제동할 때의 관성에너지(운동에너지)를 정유압변환기(5)와 고압축압기(11)에 의해 흡수하여 유압적으로 정지하였다가, 다시 자전거를 기동할 때는 고압축압기(11)에 축적된 유압 에너지와 정유압변환기(5)를 이용하여 큰 기동력으로 평지나 경사진 언덕길을 오를 수 있도록 도와주는 제동력흡수 및 유압식 기동 동력 전달 장치의 구성이 목적이다.The inertial energy (kinetic energy) at the time of braking the bicycle is absorbed by the hydrostatic converter 5 and the high-pressure compressor 11 to be stopped hydraulically, and when the bicycle is started again, it is accumulated in the high-pressure compressor 11. It is the purpose of the configuration of the braking force absorption and hydraulic starting power transmission device that helps to climb a flat or sloped hill road with a large maneuvering force by using the hydraulic energy and the hydrostatic transducer (5).

자전거 운전자의 체중을 실어 초기에 평지나 경사진 언덕을 오르는 것은 상당한 초기 기동력이 요구된다. 이와는 반대로 속도를 내고있는 상태에서나 경사진 비탈길을 내려올 때는 운전자의 체중과 자전거의 무게에 기인하는 관성력을 브레이크의 마찰에 의해 제동시키게 되며, 이와 같은 과정을 항상 반복하며 자전거를 운전하도록 한 장치가 종래의 자전거이다.Climbing a flat or sloping hill initially with the weight of a cyclist requires significant initial maneuverability. On the contrary, when the vehicle is running at a speed or down a slope, the inertia force caused by the driver's weight and the weight of the bicycle is braked by the friction of the brakes. It's a bicycle.

운동에너지를 흡수 및 제동하는 기계식 브레이크의 기능을 대신하는 정유압변환기(5)와 고압축압기(11)의 구성으로 운전자가 부드럽게 제동작용을 할수있게 하고, 정지상태의 자전거와 운전자의 체중을 기동함에 있어 오로지 운전자의 힘에 의해 페달을 밟아 기동하던 것을 축압된 유압에너지를 효율적으로 이용하여 원활하게 기동할 수 있게 하는 유압식 제동 및 기동 동력 전달 장치의 구성The hydrostatic converter (5) and the high pressure compressor (11), which replaces the function of the mechanical brake to absorb and brake the kinetic energy, allow the driver to perform a smooth braking action, and to start the bicycle and the weight of the driver Configuration of hydraulic braking and starting power transmission device that allows the user to smoothly start by using the accumulated hydraulic energy efficiently by stepping on the pedal by the driver's power

자전거 운전자가 조작하는 일련의 싸이클은 운전중에 정지할 목적으로 핸들의 오른쪽 손잡이의 레버(9)를 잡아당기면 펌프 또는 모터의 이중 역할을 하는 정유압변환기(5)는 펌프로 작동되어 저압축압기(10)으로부터 흡입하고, 토출되는 유압동력을 고압축압기(11)에 저장하면서 제동하게되며 그 압력으로 유압식 브레이크를 작동시켜 정지하게된다. 정지상태에서 다시 출발하기 위해 자전거에 타고 핸들의 좌측레버(1)을 잡아당기면 고압축압기(11)에 저장되어있던 유압에너지는 다시 정유압변환기(5)가 유압모터로 작동되게 동력이 전달되고 운전자를 태운 자전거는 정유압변환기(5)의 기동토크에 의해 초기 기동하게된다.The series of cycles operated by the cyclist pulls the lever 9 of the handle on the right side of the handle for the purpose of stopping during operation. The hydrostatic converter 5, which acts as a dual pump or motor, is pumped to operate the low pressure compressor ( 10) and the hydraulic power to be discharged and stored in the high-pressure compressor (11) is braked while operating the hydraulic brake at that pressure to stop. If you pull on the left lever (1) of the steering wheel to start again from the standstill state, the hydraulic energy stored in the high pressure compressor (11) is transferred to the hydrostatic converter (5) to operate the hydraulic motor and the driver Bicycle is initially started by the starting torque of the hydrostatic converter (5).

제동기능의 흐름을 상세히 설명하면 핸들의 우측 손잡이의 레버(9)를 조작하면 중립위치에 있던 방향전환밸브(3)는 제2위치로 움직이게 되어 제동되는 동안의 자전거이동은 정유압변환기(5)가 펌프로 작동되어 고압축압기(11)에 유압동력이 축적됨과 동시에 유압식 마찰브레이크(12)에 압력이 작용하여 완전 제동하게 되고, 우측 손잡이의 레버(9)를 해제하면 방향전환밸브(3)은 스프링(2)의 힘에 의해 중립위치로 복귀하게된다.The flow of the braking function will be described in detail. When the lever 9 of the right handle of the handle is operated, the direction change valve 3 in the neutral position moves to the second position, so that the movement of the bicycle during braking is performed by the hydrostatic transducer 5. Is operated as a pump to accumulate hydraulic power in the high-pressure compressor (11) and at the same time pressure acts on the hydraulic friction brake (12) to completely brake. When the lever (9) of the right handle is released, the directional valve (3) The force of the spring 2 returns to the neutral position.

다시 기동하기 위해 핸들의 좌측레버(1)을 조작하면 방향전환밸브(3)은 제1위치로 움직여 고압축압기(11)에 축적된 유압동력이 정유압변환기(5)에 공급되어 유압모터로 작동되고 유압모터로부터 귀환하는 저압작동유는 저압축압기(10)으로 들어가게되며, 초기 구동 후에 좌측레버(1)을 놓으면 방향전환밸브(3)은 스프링(2)의 힘에 의해 중립위치로 복귀하게된다.When the left lever (1) of the handle is operated to start again, the direction change valve (3) moves to the first position so that the hydraulic power accumulated in the high pressure compressor (11) is supplied to the hydrostatic pressure converter (5) to operate as a hydraulic motor. And the low pressure hydraulic oil returning from the hydraulic motor enters the low pressure compressor (10). When the left lever (1) is released after the initial driving, the direction switching valve (3) returns to the neutral position by the force of the spring (2). .

자전거 운전자가 경험하게 되는 언덕길의 오르막에서 피로한 운전으로부터 다소 자유로워지며 운전자의 피로감을 덜어 장거리운전이 가능하게 되고 자전거에서 내려 끌고 가는 시간보다 자전거에 앉아 운전하는 시간이 많아서 운전시간을 단축시킬 뿐만 아니라, 운동의 효율을 증대시키는 효과가 있다.As a cyclist experiences uphill hills, you are freed from tired driving, and you can reduce the driver's fatigue and make long distance driving. This has the effect of increasing the efficiency of exercise.
