후륜구동차량용 회생제동시스템{regenerative breaking system for rear wheel drive vehicle}Regenerative braking system for rear wheel drive vehicle

본 발명은 후륜구동차량의 리어액슬하우징에 구비되어 차량의 거동을 효과적으로 제어할 수 있도록 된 새로운 구조의 후륜구동차량용 회생제동시스템에 관한 것이다.The present invention relates to a regenerative braking system for a rear-wheel drive vehicle with a new structure that is installed in the rear axle housing of a rear-wheel drive vehicle to effectively control the vehicle's behavior.

일반적으로, 화물차의 경우, 도 1에 도시한 바와 같이, 후륜이 리어액슬하우징(1)에 구비된 좌우측 액슬샤프트(7,8)에 연결된다.Generally, in the case of a truck, as shown in FIG. 1, the rear wheels are connected to the left and right axle shafts 7 and 8 provided in the rear axle housing 1.

이러한 회생제동시스템은 다양한 형태로 개발되어 사용되고 있다.These regenerative braking systems have been developed and used in various forms.

그런데, 이러한 회생제동시스템은 구조가 복잡하고, 차량의 승차감에 영향을 줄 수 있을 뿐 아니라, 지금까지는 화물차 등에 적용할 수 있는 회생제동시스템이 개발되지 못하였다.However, this regenerative braking system has a complex structure and can affect the riding comfort of the vehicle, and so far, a regenerative braking system that can be applied to trucks, etc. has not been developed.

따라서, 이러한 문제점을 해결할 수 있는 새로운 방법이 필요하게 되었다.Therefore, a new method to solve these problems has become necessary.

한편, 이러한 화물차에는 차량의 조향장치가 구비된다.Meanwhile, these trucks are equipped with a vehicle steering device.

상기 조향장치는 운전자가 핸들(11)을 이용하여 회전시키는 스티어링샤프트(12)가 구비되어, 운전자가 상기 핸들(11)을 이용하여 스티어링샤프트(12)를 좌우방향으로 회전시키면, 전륜의 방향이 조정되도록 구성된다.The steering device is provided with a steering shaft 12 that the driver rotates using the handle 11, and when the driver rotates the steering shaft 12 left and right using the handle 11, the direction of the front wheels changes.

상기 좌우측 피동기어(26,36)는 중앙부에 결합된 회전축(26a,36a)에 의해 상기 좌우측 외부케이스(21,31)에 결합된다.The left and right driven gears 26 and 36 are coupled to the left and right outer cases 21 and 31 by rotating shafts 26a and 36a coupled to the central portion.

상기 좌우측 발전기(23,33)는 구동축(23a,33a)이 회전되면 발전을 하도록 구성되며 상기 좌우측 외부케이스(21,31)의 외측, 즉, 상기 좌측 외부케이스(21)의 외측과 우측 외부케이스(31)의 우측에 각각 고정된다.The left and right generators (23, 33) are configured to generate power when the drive shafts (23a, 33a) are rotated, and are located on the outside of the left and right outer cases (21, 31), that is, the outside of the left outer case (21) and the right outer case. Each is fixed to the right of (31).

상기 좌우측 클러치(24,34)는 상기 구동축(23a,33a)과 회전축(26a,36a)을 연결하는 건식다판클러치를 이용하는 것으로, 평상시에는 도 4 및 도 5에 도시한 바와 같이, 구동축(23a,33a)과 회전축(26a,36a)의 연결을 해제하고, 도 9 및 도 12에 도시한 바와 같이, 전방으로 연장된 아암(24a,34a)의 선단부를 외측, 즉, 좌측 클러치(24)는 좌측으로, 우측 클러치(34)는 우측으로 회동되면 상기 구동축(23a,33a)과 회전축(26a,36a)을 물리적으로 연결하여 회전축(26a,36a)의 구동력이 구동축(23a,33a)으로 전달되도록 한다.The left and right clutches 24 and 34 use dry multi-plate clutches that connect the drive shafts 23a and 33a and the rotation shafts 26a and 36a. As shown in FIGS. 4 and 5, the drive shafts 23a and 34 are normally used as shown in FIGS. 4 and 5. 33a) and the rotation shafts 26a and 36a are disconnected, and as shown in FIGS. 9 and 12, the front ends of the arms 24a and 34a extending forward are moved to the outside, that is, the left clutch 24 is moved to the left. When the right clutch 34 is rotated to the right, it physically connects the drive shafts 23a, 33a and the rotation shafts 26a, 36a so that the driving force of the rotation shafts 26a, 36a is transmitted to the drive shafts 23a, 33a. .

이때, 상기 좌우측 클러치(24,34)는 상기 아암(24a,34a)이 외측으로 조금 회동되면 구동축(23a,33a)과 회전축(26a,36a)을 약한 힘으로 연결하여, 회전축(26a,36a)이 회전력이 구동축(23a,33a)으로 조금만 전달되도록 하고, 아암(24a,34a)이 외측으로 점점 큰 각도로 회동될수록 구동축(23a,33a)과 회전축(26a,36a)을 점점 더 강하게 연결하도록 구성된다.At this time, the left and right clutches 24 and 34 connect the drive shafts 23a and 33a and the rotation shafts 26a and 36a with a weak force when the arms 24a and 34a are slightly rotated outward, thereby connecting the rotation shafts 26a and 36a. This rotational force is transmitted only slightly to the drive shafts (23a, 33a), and as the arms (24a, 34a) are rotated outward at increasingly larger angles, the drive shafts (23a, 33a) and the rotation shafts (26a, 36a) are connected more and more strongly. do.

이와 같이 아암(24a,34a)의 회동각도에 따라 동력을 전달하는 정도가 커지도록 된 건식다판클러치는 일반적으로 사용되는 것임으로, 이에 대한 더 이상 자세한 설명은 생략한다.As such, a dry multi-plate clutch in which the degree of power transmission increases depending on the rotation angle of the arms 24a and 34a is generally used, and further detailed description thereof will be omitted.

상기 지지블록(41)은 후륜자동차의 차체에 고정되는 것으로, 상기 랙기어(42)가 결합되는 슬라이드공(41a)이 양측면을 관통하도록 형성되고, 상기 슬라이드공(41a)의 중앙부 후측에는 슬라이드공(41a)과 교차하는 관통공(41b)이 상하면을 관통하도록 형성된다.The support block 41 is fixed to the body of a rear-wheel vehicle, and the slide hole 41a to which the rack gear 42 is coupled is formed to penetrate both sides, and a slide hole is provided at the rear of the center of the slide hole 41a. A through hole (41b) intersecting with (41a) is formed to penetrate the upper and lower surfaces.

상기 관통공(41b)은 상기 스티어링샤프트(12)가 상하방향으로 관통하도록 결합된다.The through hole 41b is coupled so that the steering shaft 12 penetrates in the vertical direction.

상기 랙기어(42)는 측방향으로 연장되며 후측면에 기어열이 형성된 봉형상으로 구성되며, 양단이 상기 지지블록(41)의 양측으로 연장된다.The rack gear 42 extends laterally and has a rod shape with a gear train formed on the rear side, and both ends extend to both sides of the support block 41.

상기 피니언기어(43)는 스티어링샤프트(12)에 결합되어 상기 관통공(41b)에 삽입됨으로써, 전방둘레부가 상기 랙기어(42)에 치합된다.The pinion gear 43 is coupled to the steering shaft 12 and inserted into the through hole 41b, so that the front peripheral portion meshes with the rack gear 42.

따라서, 운전자가 스티어링샤프트(12)를 좌측으로 회전시키면 도 8에 도시한 바와 같이, 피니언기어(43)가 좌측으로 회전되면서 랙기어(42)를 좌측으로 슬라이드되고, 반대로 도 11에 도시한 바와 같이, 스티어링샤프트(12)를 우측으로 회전시키면 랙기어(42)가 우측으로 슬라이드된다.Therefore, when the driver rotates the steering shaft 12 to the left, as shown in FIG. 8, the pinion gear 43 rotates to the left and the rack gear 42 slides to the left, and conversely, as shown in FIG. 11. Likewise, when the steering shaft 12 is rotated to the right, the rack gear 42 slides to the right.

상기 좌우측 구동실린더기구(44,45)는 내부에 구비된 피스톤(44a,45a)이 상기 랙기어(42)의 양단에 각각 결합된다.The left and right driving cylinder mechanisms 44 and 45 have pistons 44a and 45a respectively coupled to both ends of the rack gear 42.

그리고, 상기 좌우측 구동실린더기구(44,45)의 외측, 즉, 상기 피스톤(44a,45a)에서 상기 랙기어(42)가 연결되는 쪽의 반대쪽에, 각각 좌우측 유압챔버(44b,45b)가 형성된다.And, left and right hydraulic chambers 44b and 45b are formed on the outside of the left and right driving cylinder mechanisms 44 and 45, that is, on the opposite side of the piston 44a and 45a to which the rack gear 42 is connected. do.

따라서, 상기 랙기어(42)가 좌측 또는 우측으로 슬라이드되면 좌우측 구동실린더기구(44,45)의 피스톤(44a,45a)이 동시에 좌측 또는 우측으로 이동하면서 좌측 또는 우측 유압챔버(44b,45b)에 저장된 오일을 가압한다.Therefore, when the rack gear 42 slides to the left or right, the pistons 44a and 45a of the left and right driving cylinder mechanisms 44 and 45 simultaneously move to the left or right and enter the left or right hydraulic chambers 44b and 45b. Pressurize the stored oil.

상기 좌우측 유압관(46,47)은 강도가 높은 금속재로 구성된다.The left and right hydraulic pipes 46 and 47 are made of a high-strength metal material.

상기 좌우측 리저브탱크(53,54)는 내부에 공간부가 형성되어, 상기 좌우측 유압챔버(44b,45b)에서 오일이 배출되면 이를 내부에 저장하고, 좌우측 유압챔버(44b,45b)의 체적변화에 따라 내부에 저장된 오일을 좌우측 유압챔버(44b,45b)로 공급하도록 구성된다.The left and right reserve tanks (53, 54) have a space formed inside them, and when oil is discharged from the left and right hydraulic chambers (44b, 45b), it is stored therein, and according to the volume change of the left and right hydraulic chambers (44b, 45b). It is configured to supply the oil stored inside to the left and right hydraulic chambers (44b, 45b).

상기 회전각도감지센서(55)는 상기 관통공(41b)의 내부에 구비되어 상기 피니언기어(43)의 둘레부에 레이저를 조사하고 조사된 레이저를 수신하여, 피니언기어(43)의 회전방향과 각도를 측정하는 비접촉식 센서를 이용한다.The rotation angle sensor 55 is provided inside the through hole 41b to radiate a laser to the circumference of the pinion gear 43 and receive the irradiated laser to determine the rotation direction and direction of the pinion gear 43. It uses a non-contact sensor to measure angles.

이와 같이 구성된 후륜구동차량용 회생제동시스템의 작용을 설명하면 다음과 같다.The operation of the regenerative braking system for rear-wheel drive vehicles configured in this way is explained as follows.

우선, 도 6에 도시한 바와 같이, 상기 스티어링샤프트(12)가 회전되지 않은 상태, 즉, 후륜구동차량이 전진하는 상태에서는, 상기 좌우측 실린더기구(25,35)는 신장된 상태를 유지하며, 이에 따라,도 4 및 도 5에 도시한 바와 같이, 상기 좌우측 클러치(24,34)의 연결이 해제되어, 좌우측 회생제동유닛(20,30)은 작동되지 않는다.First, as shown in FIG. 6, when the steering shaft 12 is not rotated, that is, when the rear-wheel drive vehicle is moving forward, the left and right cylinder mechanisms 25 and 35 maintain an extended state, Accordingly, as shown in FIGS. 4 and 5, the left and right clutches 24 and 34 are disconnected, and the left and right regenerative braking units 20 and 30 are not operated.

즉, 차량이 전진됨에 따라, 좌우측 액슬샤프트(7,8)와 좌우측 구동기어(22,32)는 회전되는데, 좌우측 클러치(24,34)의 연결이 해제되어, 좌우측 발전기(23,33)는 구동되지 않는다.That is, as the vehicle moves forward, the left and right axle shafts (7, 8) and the left and right driving gears (22, 32) are rotated, and the left and right clutches (24, 34) are disconnected, so the left and right generators (23, 33) are It doesn't run.

그리고, 도 8에 도시한 바와 같이, 운전자가 핸들(11)을 좌측으로 돌려 상기 스티어링샤프트(12)가 좌측으로 회전되도록 하면, 상기 피니언기어(43)에 의해 랙기어(42)와 좌우측 구동실린더기구(44,45)의 피스톤(44a,45a)이 좌측으로 밀리게 된다.As shown in FIG. 8, when the driver turns the steering wheel 11 to the left so that the steering shaft 12 rotates to the left, the rack gear 42 and the left and right drive cylinders are rotated by the pinion gear 43. The pistons 44a and 45a of the mechanisms 44 and 45 are pushed to the left.

이때, 상기 제어수단(56)은 상기 회전각도감지센서(55)를 통해 이를 확인하고, 상기 좌측 공급제어밸브(48)와 우측 연결밸브(52)를 개방하고, 좌측 연결밸브(51)와 우측 공급제어밸브(49)를 밀폐한다.At this time, the control means 56 confirms this through the rotation angle detection sensor 55, opens the left supply control valve 48 and the right connection valve 52, and opens the left connection valve 51 and the right connection valve 52. Close the supply control valve (49).

따라서, 좌측 구동실린더기구(44)의 좌측 유압챔버(44b)에 저장된 오일이 가압되어, 좌측 유압관(46)을 통해 좌측 실린더기구(25)로 공급되며, 우측 리저브탱크(54)에 저장된 오일이 우측 유압챔버(45b)로 공급된다.Accordingly, the oil stored in the left hydraulic chamber 44b of the left drive cylinder mechanism 44 is pressurized and supplied to the left cylinder mechanism 25 through the left hydraulic pipe 46, and the oil stored in the right reserve tank 54 This is supplied to the right hydraulic chamber (45b).

그리고, 도 9에 도시한 바와 같이, 좌측 실린더기구(25)로 공급된 오일에 의해 좌측 실린더기구(25)가 축소되면서 좌측 클러치(24)의 아암(24a)을 외측으로 회동시켜 좌측 클러치(24)가 좌측 피동기어(26)의 회전축(26a)과 좌측 발전기(23)의 구동축(23a)을 연결함으로써, 좌측 발전기(23)가 발전을 하게 된다.As shown in FIG. 9, the left cylinder mechanism 25 is contracted by the oil supplied to the left cylinder mechanism 25, and the arm 24a of the left clutch 24 is rotated outward to rotate the left clutch 24. ) connects the rotation shaft 26a of the left driven gear 26 and the drive shaft 23a of the left generator 23, so that the left generator 23 generates power.

한편, 이와 같이 좌측 발전기(23)가 발전을 하게 되면, 좌측 발전기(23)에서 발생되는 부하에 의해 좌측 액슬샤프트(7)에 부하가 가해져 좌측 바퀴에 제동이 걸리게 된다.Meanwhile, when the left generator 23 generates power in this way, a load is applied to the left axle shaft 7 due to the load generated by the left generator 23, causing braking to be applied to the left wheel.

즉, 우측 바퀴는 제동이 걸리지 않고 좌측 바퀴에만 제동이 걸리게 됨으로, 차량이 좌측으로 더욱 원활하게 회전될 수 있다.In other words, the right wheel is not braked and only the left wheel is braked, so the vehicle can turn to the left more smoothly.

그리고, 운전자가 도 10에 도시한 바와 같이, 좌측으로 회전된 스티어링샤프트(12)를 초기위치로 복귀시키면, 상기 랙기어(42)가 중앙부로 복귀되며, 이에 따라, 상기 좌측 실린더기구(25)의 오일챔버(25b)로 공급된 오일이 좌측 구동실린더기구(44)의 좌측 유압챔버(44b)로 복구되고, 우측 유압챔버(45b) 내부의 오일은 우측 리저브탱크(54)로 배출된다.And, as shown in FIG. 10, when the driver returns the steering shaft 12 rotated to the left to its initial position, the rack gear 42 returns to the center, and accordingly, the left cylinder mechanism 25 The oil supplied to the oil chamber 25b is returned to the left hydraulic chamber 44b of the left driving cylinder mechanism 44, and the oil inside the right hydraulic chamber 45b is discharged to the right reserve tank 54.

그리고, 반대로 운전자가 도 11에 도시한 바와 같이, 스티어링샤프트(12)를 우측으로 회전시키면, 상기 피니언기어(43)에 의해 랙기어(42)와 좌우측 구동실린더기구(44,45)의 피스톤(44a,45a)이 우측으로 밀리게 된다.Conversely, when the driver rotates the steering shaft 12 to the right as shown in FIG. 11, the pinion gear 43 moves the rack gear 42 and the pistons of the left and right drive cylinder mechanisms 44 and 45 ( 44a, 45a) are pushed to the right.

이때, 상기 제어수단(56)은 회전각도감지센서(55)의 신호를 통해 이를 확인하고, 상기 우측 공급제어밸브(49)와 좌측 연결밸브(51)를 개방하고, 우측 연결밸브(52)와 좌측 공급제어밸브(48)를 밀폐한다.At this time, the control means 56 confirms this through the signal of the rotation angle detection sensor 55, opens the right supply control valve 49 and the left connection valve 51, and connects the right connection valve 52 and Close the left supply control valve (48).

따라서, 우측 구동실린더기구(45)의 우측 유압챔버(45b)에 저장된 오일이 가압되어, 우측 유압관(47)을 통해 우측 실린더기구(35)로 공급되며, 좌측 리저브탱크(53)에 저장된 오일이 좌측 유압챔버(44b)로 공급된다.Accordingly, the oil stored in the right hydraulic chamber 45b of the right driving cylinder mechanism 45 is pressurized and supplied to the right cylinder mechanism 35 through the right hydraulic pipe 47, and the oil stored in the left reserve tank 53 This is supplied to the left hydraulic chamber (44b).

그리고, 도 12에 도시한 바와 같이, 우측 실린더기구(35)로 공급된 오일에 의해 우측 실린더기구(35)가 축소되면서 우측 클러치(34)의 아암(34a)을 외측으로 회동시켜 우측 클러치(34)가 우측 피동기어(36)의 회전축(36a)과 우측 발전기(33)의 구동축(33a)을 연결함으로써, 우측 발전기(33)가 발전을 하게 되며, 우측 발전기(33)에서 발생되는 부하에 의해 우측 액슬샤프트(8)에 부하가 가해져 우측 바퀴에 제동이 걸리게 된다.And, as shown in FIG. 12, the right cylinder mechanism 35 is contracted by the oil supplied to the right cylinder mechanism 35, and the arm 34a of the right clutch 34 is rotated outward to rotate the right clutch 34. ) connects the rotation shaft 36a of the right driven gear 36 and the drive shaft 33a of the right generator 33, so that the right generator 33 generates power, and the load generated from the right generator 33 generates power. A load is applied to the right axle shaft (8), causing braking to be applied to the right wheel.

즉, 좌측 바퀴는 제동이 걸리지 않고 우측 바퀴에만 제동이 걸리게 됨으로, 차량이 우측으로 더욱 원활하게 회전될 수 있다.In other words, the left wheel is not braked and only the right wheel is braked, so the vehicle can turn to the right more smoothly.

이와 같이 구성된 후륜구동차량용 회생제동시스템에 따르면, 액슬하우징에 구비된 좌우측 샤프트챔버(3,4)에 각각 좌우측 회생제동유닛(20,30)이 구비되고, 운전자가 핸들(11)을 돌려 스티어링샤프트(12)가 좌우방향으로 회전되면, 좌측 또는 우측 회생제동유닛(20,30)이 작동되어 발전을 하게 된다According to the regenerative braking system for a rear-wheel drive vehicle configured as described above, left and right regenerative braking units (20, 30) are provided in the left and right shaft chambers (3, 4) provided in the axle housing, respectively, and the driver turns the handle (11) to control the steering shaft. When (12) is rotated left and right, the left or right regenerative braking units (20, 30) are activated to generate power.

따라서, 이와 같이 발전된 전기를 이용하여, 차량의 연비를 향상시킬 수 있을 뿐 아니라, 차량이 좌측 또는 우측으로 더욱 원활히 선회하도록 지원할 수 있는 장점이 있다.Therefore, by using the electricity generated in this way, there is an advantage in that not only can the fuel efficiency of the vehicle be improved, but it can also help the vehicle turn more smoothly to the left or right.
