Description

무단 변속기{CONTINUOUSLY VARIABLE TRANSMISSION}Continuously variable transmission {CONTINUOUSLY VARIABLE TRANSMISSION}

본 발명은 무단 변속기에 관한 것으로, 보다 상세하게는 무단 변속기의 전장을 단축할 수 있는 무단 변속기에 관한 것이다.The present invention relates to a continuously variable transmission, and more particularly to a continuously variable transmission that can shorten the overall length of the continuously variable transmission.

일반적으로 차량의 변속장치는 엔진의 구동력을 구동륜에 전달하는 기능을 갖고 있는데, 이러한 변속장치에는 운전자의 의지대로 운전자가 직접 변속단을 선택하는 수동 변속기와, 차량의 주행 조건에 따라 자동적으로 변속이 이루어지는 자동 변속기와, 각 변속단 사이에 특정한 변속 영역이 없이 무단으로 연속적인 변속이 이루어지는 무단 변속기로 대별된다. 이러한 무단 변속기는 입력축과 출력축에 장착되는 풀리의 직경변위를 이용하는 방식이 주로 이용된다.In general, the transmission of the vehicle has a function of transmitting the driving force of the engine to the drive wheels. Such a transmission includes a manual transmission in which the driver directly selects a shift stage at the driver's will, and the shift is automatically performed according to the driving conditions of the vehicle. It is divided into the automatic transmission which is made, and the continuously variable transmission in which continuous transmission is continuously performed without a specific speed change area between each transmission stage. Such continuously variable transmissions are mainly used by using the diameter displacement of the pulley mounted on the input shaft and the output shaft.

도 1은 종래 기술에 따른 무단 변속기의 프라이머리 풀리 부분을 개략적으로 도시한 요부 단면도이다.1 is a cross-sectional view illustrating main parts of a primary pulley of a continuously variable transmission according to the related art.

도 1에 도시된 바와 같이, 종래 무단 변속기 벨트 풀리 시스템(1)의 프라이머리 풀리(3)는 고정측 풀리(5)와 가변측 풀리(7)로 이루어지며, 고정측 풀리(5)는 입력축(9)에 일체로 형성되어 있으며, 가변측 풀리(7)는 입력축(9)에 좌우 이동될 수 있도록 결합된다.As shown in FIG. 1, the primary pulley 3 of the conventional continuously variable transmission belt pulley system 1 includes a fixed side pulley 5 and a variable side pulley 7, and the fixed side pulley 5 has an input shaft. It is formed integrally with (9), the variable side pulley (7) is coupled to be moved left and right on the input shaft (9).

상기 가변측 풀리(7)에는 피스톤(2)이 삽입되어 이들 사이에 유압챔버(4)가 형성되며, 이 유압챔버(4)는 입력축(9)에 형성된 유로(6)를 통하여 엔진의 구동력에 의하여 형성되는 압력 유체(8)가 공급된다.A piston (2) is inserted into the variable side pulley (7) and a hydraulic chamber (4) is formed therebetween. The hydraulic chamber (4) is connected to the driving force of the engine through a flow path (6) formed on the input shaft (9). The pressure fluid 8 formed by this is supplied.

상기 입력축(9)에는 유압챔버(4)에서 발생되는 압력을 지지하는 락킹 너트(11)가 결합되며, 락킹 너트(11)와 피스톤(2)의 사이에는 베어링 부재(13)가 설치된다.A locking nut 11 supporting the pressure generated in the hydraulic chamber 4 is coupled to the input shaft 9, and a bearing member 13 is installed between the locking nut 11 and the piston 2.

이에 따라, 유압챔버(4) 내에서 발생된 압력은 가변측 풀리(7)에 전달되어 가변측 풀리(7)를 작동시키는 구조를 갖는다.Accordingly, the pressure generated in the hydraulic chamber 4 is transmitted to the variable side pulley 7 to operate the variable side pulley 7.

그러나, 상기 구성을 갖는 종래 무단 변속기는 유압챔버(4)에서 발생되는 압력을 지지하기 위하여 락킹 너트(11)의 직경과 길이를 크게 하여 유압챔버(4) 내의 압력을 지지함으로써, 무단 변속기의 전장이 길어지는 문제점이 있다.However, the conventional continuously variable transmission having the above-described configuration increases the diameter and length of the locking nut 11 to support the pressure generated in the hydraulic chamber 4, thereby supporting the pressure in the hydraulic chamber 4, thereby increasing the overall length of the continuously variable transmission. There is a problem with this lengthening.

본 발명은 상기 전술한 바와 같은 문제점들을 해결하기 위해 창출된 것으로서, 무단 변속기의 프라이머리 풀리의 피스톤과 입력축과의 결합을 견고하게 하며, 무단변속기의 전장을 단축할 수 있는 무단 변속기를 제공하는데 그 목적이 있다.SUMMARY OF THE INVENTION The present invention has been made to solve the problems described above, and provides a continuously variable transmission that can secure the coupling between the piston and the input shaft of the primary pulley of the continuously variable transmission and can shorten the overall length of the continuously variable transmission.

상기 목적을 달성하기 위한 본 발명의 무단 변속기는, 프라이머리 풀리의 가변측 풀리 및 피스톤이 입력축에 삽입되어 가변측 풀리와의 사이에 유압챔버가 형성되며, 이 유압챔버는 입력축에 형성된 유로를 통하여 엔진의 구동력에 의하여 발생된 유압의 공급에 따라 직경이 가변되면서 변속비를 제어하는 무단 변속기에 있어서, 상기 피스톤은 입력축에 나사결합으로 결합되고, 상기 피스톤 외측에는 베어링 부재가 장착되며, 상기 베어링 부재는 베어링 지지 너트부재로 고정된다.In the continuously variable transmission of the present invention for achieving the above object, a variable side pulley and a piston of a primary pulley are inserted into an input shaft, and a hydraulic chamber is formed between the variable side pulley, and the hydraulic chamber is formed through a flow path formed in the input shaft. In the continuously variable transmission for controlling the speed ratio while changing the diameter according to the supply of the hydraulic pressure generated by the driving force of the engine, the piston is coupled to the input shaft by screwing, the bearing member is mounted on the outside of the piston, the bearing member It is fixed by the bearing support nut member.

이하 본 발명의 바람직한 실시예에 따른 무단 변속기를 첨부된 도면을 참조하여 상세히 설명한다. 그러나 본 발명은 이하에서 개시되는 실시예에 한정되는 것이 아니라 서로 다른 다양한 형태로 구현될 것이며, 단지 본 실시예는 본 발명의 개시가 완전하도록 하며, 통상의 지식을 가진자에게 발명의 범주를 완전하게 알려주기 위해 제공되는 것이다.Hereinafter, a continuously variable transmission according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but will be implemented in various forms, and only the present embodiments are intended to complete the disclosure of the present invention and to those skilled in the art to fully understand the scope of the invention. It is provided to inform you.

도 2는 본 발명의 바람직한 실시예에 따른 무단 변속기의 프라이머리 풀리 측을 개략적으로 도시한 도면이다.2 is a view schematically showing a primary pulley side of a continuously variable transmission according to a preferred embodiment of the present invention.

도 2에 도시된 바와 같이, 본 발명에 따른 무단 변속기(100)는, 프라이머리 풀리의 가변측 풀리(10)와, 피스톤(20)이 입력축(30)에 삽입되어 가변측 풀리(10)와의 사이에 유압챔버(40)가 형성되며, 이 유압챔버(40)는 입력축(30)에 형성된 유로(31)를 통하여 엔진의 구동력에 의하여 발생된 유압(33)의 공급에 따라 직경이 가변되면서 변속비를 제어하는 무단 변속기에 있어서, 상기 피스톤(20)은 입력축(30)에 나사결합으로 결합되고, 상기 피스톤(20) 외측에는 베어링 부재(50)가 장착되며, 상기 베어링 부재(50)는 베어링 지지 너트부재(60)로 고정된다.As shown in FIG. 2, in the continuously variable transmission 100 according to the present invention, the variable pulley 10 of the primary pulley and the piston 20 are inserted into the input shaft 30 to be connected to the variable pulley 10. An oil pressure chamber 40 is formed between the oil pressure chambers 40 while the oil pressure chamber 40 varies in diameter depending on the supply of oil pressure 33 generated by the driving force of the engine through the oil passage 31 formed on the input shaft 30. In the continuously variable transmission, the piston 20 is screwed to the input shaft 30, the bearing member 50 is mounted to the outside of the piston 20, the bearing member 50 is bearing support The nut member 60 is fixed.

상기의 구성을 갖는 본 발명에 따른 무단 변속기의 작용을 설명한다.The operation of the continuously variable transmission according to the present invention having the above configuration will be described.

본 발명의 무단 변속기(100)의 피스톤(20)과 입력축(30)과의 결합을 나사 결합으로 결합한다. 이에 따라, 유압챔버(40)로 유입되는 유압(33)의 압력은 피스톤(20)과 입력축(30)과의 나사 결합의 결합력에 의하여 지지된다. Coupling the piston 20 of the continuously variable transmission 100 and the input shaft 30 of the present invention by screw coupling. Accordingly, the pressure of the hydraulic pressure 33 flowing into the hydraulic chamber 40 is supported by the coupling force of the screw coupling between the piston 20 and the input shaft 30.

상기 피스톤(20)의 외측에는 베어링 부재(50)가 설치되고, 이 베어링 부재(50) 외측에는 베어링 지지 너트부재(60)로 고정된다. 이 베어링 지지 너트부재(60)는 베어링 부재(50)의 지지를 위한 역할만을 수행한다. 즉, 유압챔버(40) 내의 유압(33)의 압력을 피스톤(20)과 입력축(30)과의 나사 결합구조에 의하여 지지하게 됨으로써, 베어링지지 너트부재(60)는 베어링 부재(50) 지지의 역할만을 하는 정도의 크기와 직경으로 구비될 수 있도록 한다. 이에 따라, 종래 기술보다 적은 사양의 너트부재로 장착할 수 있도록 하여, 밸트-풀리기구의 작동을 위해 발생되는 힘을 원활하게 지지하며 무단 변속기의 전장을 단축할 수 있다.A bearing member 50 is installed outside the piston 20, and is fixed to the bearing support nut member 60 outside the bearing member 50. The bearing support nut member 60 only serves to support the bearing member 50. That is, the pressure of the hydraulic pressure 33 in the hydraulic chamber 40 is supported by the screw coupling structure between the piston 20 and the input shaft 30, so that the bearing support nut member 60 is supported by the bearing member 50. It can be provided with a size and diameter of a degree that only serves. Accordingly, the nut member having a smaller specification than the prior art can be mounted to smoothly support the force generated for the operation of the belt-pull mechanism and shorten the overall length of the continuously variable transmission.

상기와 같은 본 발명에 따른 무단 변속기는 다음과 같은 효과를 갖는다.The continuously variable transmission according to the present invention as described above has the following effects.

무단변속기의 프라이머 풀리의 피스톤과 입력축과의 결합을 나사 결합으로 결합되도록 하여, 피스톤에 결합되는 너트부재의 사양을 보다 낮은 사양으로 결합할 수 있도록 함으로써, 무단 변속기의 전장을 단축할 수 있다.또한 무단변속기의 프라이머 풀리의 피스톤과 입력축과의 결합을 나사 결합으로 결합되도록 하여, 밸트-풀리기구의 작동을 위해 발생되는 힘을 원활하게 지지할 수 있도록 한다.이상, 본 발명을 도면에 도시된 실시예를 참조하여 설명하였다. 그러나, 본 발명은 이에 한정되지 않고 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에 의해 본 발명과 균등한 범위에 속하는 다양한 변형예 또는 다른 실시예가 가능하다. 따라서, 본 발명의 진정한 보호범위는 이어지는 특허청구범위에 의해 정해져야 할 것이다.By combining the piston of the primer pulley of the continuously variable transmission with the input shaft by screwing, the nut member coupled to the piston can be combined to a lower specification, thereby reducing the overall length of the continuously variable transmission. The piston and the input shaft of the primer pulley of the continuously variable transmission are coupled by screwing, so that the force generated for the operation of the belt-pull mechanism can be smoothly supported. The present invention is illustrated in the drawings. It demonstrated with reference to the example. However, the present invention is not limited thereto, and various modifications or other embodiments falling within the scope equivalent to the present invention are possible by those skilled in the art.
