    Lubrication and / or cooling device for, and a continuously variable transmission system with, such a lubricating and / or cooling device
    The invention relates to a lubricating and / or cooling device for a flexible member type continuous variable transmission (CVT) system that uses an endless metal belt for transferring force between a primary pulley and a secondary pulley. Such a lubricator can also be used for cooling the flexible member or for lubricating and / or cooling the flexible member.
    As is common in such flexible member type CVTs, each of the primary and secondary pulleys includes an axially stationary cone-shaped disk half and an axially movable disk half. The flexible member can be a belt member or a chain member. The axially movable disc halves of the primary and secondary pulleys are adapted to move in laterally opposite directions. As a result, the force-transmitting belt or chain performs a lateral movement when the radius around the primary and secondary pulleys varies with the transmission ratio. For the efficiency of lubricating and / or cooling the flexible transmission belt or chain and the pulley sheaves it is important that a liquid lubricating and / or cooling medium, such as oil, is accurately distributed to the critical locations and in a sufficient amount. Several proposals have been used to spray a hydraulic medium on portions of an endless transmission element to achieve this goal, but until now none have been entirely satisfactory in light of constantly rising power ranges and efficiency requirements.
    In known systems, the hydraulic medium, such as oil, is sprayed by means of a liquid supply pipe extending between the primary and secondary pulleys. Such systems are general
    BE2017 / 5480 known from and described in patent documents EP 0 574 085 B1, US 5,605,513, US 6,068, 565, US 6,537,166 B1, WO 98/20269, US 6,626,781 B2, and US 8,672,097 B2. A single fluid supply pipe can be used with two nozzles, or two separate pipes can be used with a single nozzle each resulting in more components in the transmission. The liquid supply pipe extending between the primary and secondary pulleys is usually provided with at least two discharge openings formed as holes or nozzles for spraying the fluid under pressure on the area within which the laterally movable flexible member and disc halves are kept moving. Since one of the at least two outlet openings is downstream of the other, there is a loss of pressure in the fluid available at the downstream outlet opening relative to the upstream outlet opening. This difference in pressure has a negative effect on the spray pattern of the downstream discharge opening, which can only be compensated by differentiating between the discharge opening sizes or nozzle configurations, in particular at a specific supply pressure. With the metal pipes commonly used hitherto, this differentiation between the discharge openings would require complicated manufacturing procedures and / or expensive accessories.
    Hence, it is an object of the present invention to propose, and seek embodiments of the present invention to provide, an improved lubrication and / or cooling device for a flexible member type of continuously variable transmission system. In a more general sense, it is an object of the invention to overcome or mitigate at least one of the disadvantages of the prior art. It is also an object of the present invention to provide alternative solutions that are less difficult to assemble and operate and, moreover, that can be made relatively inexpensively. Alternatively, it is an object of the invention to offer at least one useful alternative.
    BE2017 / 5480
    For this purpose, the invention provides a lubricating and / or cooling device for a flexible member type of continuously variable transmission system, and a continuously variable transmission system, as defined by one or more of the appended claims.
    A lubricating and / or cooling device according to the invention is suitable for and may be included in a flexible member type continuous variable transmission system that includes a housing, a liquid supply source, and an endless metal belt or chain for transferring force between a primary pulley and a secondary pulley. The inventive device may include an elongate fluid lead body with a proximal end portion, a fluid inlet connectable to the fluid supply source of a continuously variable transmission system, and a distal end portion. The inventive device also includes at least a first and a second fluid discharge port, each of which is disposed on the distal end portion of the fluid lead body. The elongated fluid transit body may comprise a first fluid delivery channel in fluid communication with the first fluid delivery port, and second fluid delivery channel separate from the first fluid delivery channel. The second fluid delivery channel may be in fluid communication with the second fluid delivery port. In the lubricating and / or cooling and / or cooling device according to the invention, at least one of the first and second fluid discharge openings can be arranged to be directed transversely of the elongate fluid feed-through body. Alternatively or additionally, the first fluid discharge port may be disposed between the proximal and distal end portions, and the second fluid discharge port is located adjacent the distal end portion. Both the first and second fluid discharge openings may also be arranged to be directed transversely to the elongated fluid transit body, and / or the second fluid discharge opening may be disposed in a transverse direction radially angled to the transverse direction of the first fluid discharge opening. The smear
    BE2017 / 5480 and / or cooling and / or cooling device is suitable for use with any type of flexible member that requires active lubrication and / or cooling.
    Each of the first and second discharge openings of the device of the invention may be provided with a spray-forming nozzle, and the spray-forming nozzles of the first and second discharge openings may differ from each other.
    In an embodiment of the device of the invention, the fluid lead-through body may be advantageously shaped as a casting. In the casing, the first and second fluid transit channels may be separated by a flat wall element that is incorporated into the casting that forms the fluid transit body. The casting of the fluid lead-through body may further be made of a thermoplastic polymer. This thermoplastic polymer can be glass fiber reinforced, and / or can be a polymer class that can withstand a high temperature. The fluid lead body of the device may suitably be injection molded.
    The lubricating and / or cooling and / or cooling device of the invention may also include one or more further fluid delivery channels and associated fluid delivery openings in addition to the first and second fluid delivery channels and fluid delivery openings. In this regard, a cross-sectional area of one of the first and second discharge openings or of one of the first and second fluid passage channels may be arranged to be different from each other. At least one of the first and second fluid delivery channels may also be associated with a flow control valve. Such a flow control valve can then be arranged to be actively controlled depending on the ratio of the continuously variable transmission system.
    In a lubricating and / or cooling and / or cooling device of the invention, the fluid transit body may have a fixation lens at its proximal end portion. A central longitudinal axis of the elongate
    BE2017 / 5480 fluid lead-through body may also form an angle with respect to a mounting surface of the fixation flange.
    In a lubricating and / or cooling and / or cooling device of the invention, the fluid inlet may be generally axially disposed of the elongate fluid feed body.
    The continuously variable transmission system according to the invention may comprise a primary pulley, a secondary pulley, an endless metal belt or chain for transferring force between the primary pulley and the secondary pulley, a housing, a liquid supply source, and the lubricating and / or cooling device with one or more of the higher characteristics. In this transmission system, the lubricating and / or cooling and / or cooling device will be connected to the liquid supply source, while the liquid supply source will be arranged to provide a lubricating and / or cooling and / or cooling liquid at the first and second discharge openings of the fluid feed body. to add. The proximal end portion of the lubricating and / or cooling device will be attached to the transmission housing, and the first and second fluid discharge openings will be adapted to spray the supplied lubricating and / or cooling fluid onto contact surfaces of at least one of the endless metal belt or chain and the primary and secondary pulleys. In such a continuously variable transmission system, each of the primary and secondary pulleys may comprise an axially stationary conical disc half and an axially movable disc half. The axially movable disc halves of the primary and secondary pulleys may then be arranged to move in laterally opposite directions, and the force transmitting flexible member will thereby perform a lateral movement when the radius around the primary and secondary pulleys with a transmission ratio varies that results from controlled axial movement of the axially movable disc halves of the primary and secondary pulleys. The transmission system can then be further arranged to diverge one of the first and second fluid supply openings
    BE2017 / 5480 spraying a jet of lubricating and / or cooling fluid in a flow direction to a neighborhood of the axially fixed primary disc, and allowing the other of the first and second fluid discharge openings to have a diverging jet of lubricating and / or cooling fluid spraying in a flow direction to a neighborhood of the axially fixed secondary disc. The diverging rays can further be arranged to overlap in a central area that coincides with lateral belt or chain movement. The diverging jets of lubricating / or cooling fluid can each also be directed in a direction of belt or chain movement, and / or the diverging jets can be angled differently.
    The fluid supply source of the continuously variable transmission system of the invention may comprise at least one pump for supplying the lubricating and / or cooling fluid.
    Further advantageous aspects of the invention will be apparent from the accompanying description and with reference to the accompanying drawings, in which:
    Figure 1 shows a detail of a detail of a continuously variable transmission system comprising the lubricating and / or cooling device of the invention;
    Figure 2 is a front view of an embodiment of a lubricating and / or cooling device according to the invention;
    Figure 3 is a cross-sectional view of the embodiment of Figure 2 along the line III-III;
    Figure 4 is a cross-sectional view of the embodiment of Figure 2 along the line IV-IV;
    Figure 5 is a cross-sectional view of the embodiment of Figure 2 along the line V-V;
    Figures 6A to 6D schematically illustrate a selection of alternative transverse cross-sections comprising multiple channels;
    BE2017 / 5480
    Figure 7 is a variation with a four-channel layout first valve member; and
    Figure 8 is a second valve member for cooperating with the first valve member of Figure 7 to control the flow of lubricating fluid.
    A continuously variable transmission system, a detail of which is shown in Figure 1, typically includes a primary drive input pulley 1 driven by input shaft 2, and a secondary output pulley 3 driving an output shaft 4. A force-transmitting endless flexible metal belt or chain 5 extends between the primary pulley 1 and the secondary pulley 3. In operation, the endless metal belt or chain 5 moves in the direction of arrow A. By changing the contact diameters of the primary and secondary pulleys, the transmission ratio can be varied in a known manner. Due to the high contact pressure between opposite halves of the primary and secondary pulleys 1, 3 and the endless metal belt or chain 5, it is necessary to continuously lubricate and cool these contact surfaces. To provide this lubrication and / or cooling, a lubricating and / or cooling device is placed between the primary and secondary pulleys 1, 3. The lubricating and / or cooling device 6 sprays lubricating and / or cooling fluid in a direction B between the secondary pulley 3 and the endless metal belt or chain 5. The lubricating and / or cooling device 6 also sprays lubricating and / or cooling fluid in a direction C between the primary pulley 1 and the endless metal belt or chain 5.
    The lubricating and / or cooling device 6 is shown in more detail in Figure 2 and comprises an elongated fluid lead-through body 7, which has a proximal end portion 8 and a distal end portion 9. The proximal end portion 8 is adapted to be mounted on a transmission housing 11 (Figure 1) by means of a mounting or fixation flange 13. The mounting flange or fixation 13 as shown in Figure 3 appropriately forms an angle with respect to the elongated fluid feed body 9. The transmission housing 11 has an internal lubrication and / or cooling fluid supply,
    BE2017 / 5480 which may be connected to any of a first fluid transit channel 15 and a second fluid transit channel 17. To assist in obtaining a fluid-tight connection between the transmission housing 11 and the lubricating and / or cooling device 6, the proximal end portion 8 may also be provided with an O-ring receiving groove 19. Also placed on the elongated fluid transit body 7 is a first fluid discharge opening 21, and a second fluid discharge opening 23. The first fluid discharge opening 21 is between the proximal end portion 8 and the distal end portion 9 of the elongated fluid lead-through body 7. The second fluid discharge opening 23 is positioned immediately adjacent the distal end portion 9. The first and second fluid transit channels 15, 17, as shown in Figure 3, are separated by a wall member 25 that extends within a hollow interior of the fluid transit body 7.
    As shown in more detail in the cross-sections of Figures 4 and 5, the mounting flange 13 is provided with an opening 27 to receive a fastener, such as a bolt or screw. A reinforcement rib 29 may partially extend between the fluid lead-through body 7 and the mounting flange 13 for reinforcing the structural integrity of the lubricating and / or cooling device 6.
    As is clear from comparing the cross-section of Figure 4 taken along the line IV-IV in Figure 2, and the cross-section of Figure 5 taken along the line VV in Figure 2, the first fluid discharge opening 21 extends in one direction which is substantially opposite to that of the second discharge opening 23. In the example of Figures 2 to 5, the first and second fluid discharge openings 21, 23 are at an angle to each other, but this device can vary depending on the chosen mounting position on the transmission housing 11 and / or the required spraying direction B, C between the first and second pulleys 1, 3 as those skilled in the art will understand.
    BE2017 / 5480
    Also, each of the first and second fluid discharge openings 21, 23 may be formed as a spray nozzle, or receive a separate spray nozzle, which may be attached to it permanently or removably. To obtain the complex shape and the desired nozzle shape or nozzle receiving structure of the lubricating and / or cooling device 6 easily and cheaply, the fluid feed body 7 is best shaped as a casting. Such a casting may be injection molded in either a zamac alloy or a thermoplastic polymer, such as a glass fiber reinforced high temperature resistant polymer class.
    While the above example has been described as having separate first and second fluid delivery channels to discharge a lubricating and / or cooling fluid onto contact surfaces of primary and secondary pulleys, it is conceivable that more than two fluid delivery channels and fluid delivery openings have been used. This can be useful to increase the coverage of the contact areas to be lubricated and cooled. As schematically shown in Figure 6A, the internal structure of the elongated fluid transit body 7 can be divided in cross section into first and second fluid transit channels through a flat wall element 25, such as in the example of Figures 2 to 5. However, as shown schematically in Figure 6B, these first and second channels 15, 17 are also formed with rounded contour lines to minimize flow resistance and / or prevent deposits. As shown in Figures 6C and 6D in a similar schematic manner, the cross section of the elongated fluid transit body 7 may also be subdivided by having additional third and fourth fluid delivery channels 29, 31.
    Coinciding with the use of multiple fluid feed-through channels in the lubricating and / or cooling device 6, the fluid supply from the transmission housing 11 can also be subdivided into
    BE2017 / 5480 separate supply channels with either the same or different supply sources within the transmission.
    In a further alternative device schematically illustrated in Figures 7 and 8, the transmission housing 11 or the lubricating and / or cooling device 6 can additionally be provided with a fluid-regulating valve. Such a fluid control valve may comprise a stationary first valve member 33 (Fig. 7), and a rotatable second valve member 35 (Fig. 8). The stationary first valve member 33 has a central pivot bearing 37 and openings corresponding to the first, second, third and fourth fluid transit channels 15, 17, 29, 31. The rotating second valve member 35 as shown in Figure 8 has opposed wings 39 divided into sectors 41 opposite a central pivot axis 43. By rotating the second valve member 35 relative to the first valve member 33 corresponding to either arrow 45 or 47, the wings 39, 41 divided into sectors will to a greater or lesser extent the openings in the first valve member 33 cover or reveal. Therefore, the flow of lubricating and / or cooling fluid supplied from the transmission housing 11 to the lubricating and / or cooling device 6 can be varied according to the transmission ratio and belt or chain position.
    Accordingly, a lubricating and / or cooling device 6 is described by way of example for and / or comprising continuously variable transmission system in a belt or chain type comprising a housing 11, a liquid supply source, and an endless metal belt or chain 5 for transferring force between a primary pulley 1 and a secondary pulley 2. The device 6 comprises an elongated fluid lead-through body 7 with a proximal end portion 8 with a fluid inlet connectable to the fluid supply source and a distal end portion 9. The device also includes at least a first and a second discharge opening 21, 23, each disposed on the distal end portion of the fluid transit body 7. The elongated fluid transit body 7 comprises a first fluid passage channel 15 in fluid communication with the first fluid
    BE2017 / 5480 outlet opening 21, and second fluid delivery channel 17 separated from the first fluid delivery channel 15. The second fluid delivery channel 17 is in fluid communication with the second fluid delivery opening 23.
