Description

Technical Field

[0001] This utility model relates to the field of drive device technology, and in particular to a vertical drive device. Background Technology

[0002] Agriculture in hilly areas is a crucial component of agriculture, but due to the limitations of natural conditions, the level of agricultural mechanization is generally low. Especially in some hilly areas, crops are mainly planted on slopes with inclines, some reaching 30°, which places higher demands on the stability and mobility of agricultural machinery. Tracked chassis, due to their strong grip and good passability, have become one of the most commonly used traction chassis in hilly agricultural machinery. Based on this, the inventors have developed a remote-controlled four-wheel drive triangular tracked chassis as a traction chassis, aiming to achieve a lower center of gravity, reduce landslides and rollovers, improve operational stability, and simultaneously enhance the power performance of the triangular tracks, thereby increasing traction capabilities. The space between the four triangular tracks is used to house the engine, fuel tank, and other power equipment, leaving very limited space for the drive unit at each track. Therefore, it is necessary to consider the overall center of gravity requirements and space constraints, and provide a drive unit that works in conjunction with the triangular tracks to achieve high-power traction and movement for the entire vehicle. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a vertical drive device with high output torque, low requirements for layout space, and conducive to lowering the center of gravity of the vehicle.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a vertical drive device, including a reducer housing, the reducer housing being arranged at an incline; an output shaft is rotatably mounted on the lower part of the reducer housing, a drive motor is fixedly mounted on the top of the reducer housing, the power shaft of the drive motor being perpendicular to the output shaft; an intermediate reduction shaft is rotatably mounted inside the reducer housing, located between the power shaft and the output shaft, a reduction column gear set is provided between the intermediate reduction shaft and the output shaft, and a reduction bevel gear set is provided between the power shaft and the intermediate reduction shaft.

[0005] As a preferred technical solution, an input shaft is rotatably mounted on the top of the reducer housing. The input shaft is arranged parallel to the power shaft. A first-stage reduction gear set is provided between the power shaft and the input shaft. A reduction bevel gear set is provided between the input shaft and the intermediate reduction shaft.

[0006] As a preferred technical solution, the power shaft is located above the input shaft.

[0007] Due to the adoption of the above technical solution, the vertical drive device includes a reducer housing, which is arranged at an angle. An output shaft is rotatably mounted on the lower part of the reducer housing, and a drive motor is fixedly mounted on the top of the reducer housing. The power shaft of the drive motor is perpendicular to the output shaft. An intermediate reduction shaft is rotatably mounted inside the reducer housing, located between the power shaft and the output shaft. A reduction column gear set is provided between the intermediate reduction shaft and the output shaft, and a reduction bevel gear set is provided between the power shaft and the intermediate reduction shaft. In this invention, the power shaft and output shaft are arranged perpendicularly, enabling the reducer and drive motor to be arranged in a vertical spatial direction. Therefore, this arrangement can be implemented in a relatively narrow space between the power equipment and the triangular track, with low space requirements. The reducer housing achieves high torque output through at least two stages of reduction. The gearbox housing is tilted, which lowers the center of gravity and helps to reduce the overall center of gravity of the vehicle. The gearbox housing can be filled with a fixed amount of oil only at the bottom. During operation, the swinging motion generated by the rotation of the gears on the output shaft cools and lubricates the gears and other components at higher positions in the tilt direction. This satisfies the cooling and lubrication requirements while preventing oil from seeping into the drive motor, ensuring the long-term reliable operation of this invention.

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0016] like Figures 1 to 5 As shown, the vertical drive unit includes a reducer housing 1, which is arranged at an angle. This angled arrangement lowers the overall center of gravity of this embodiment, thus helping to lower the center of gravity of the entire vehicle.

[0017] An output shaft 11 is rotatably mounted on the lower part of the reducer housing 1. The output shaft 11 is used for power connection with the triangular track 8 to achieve power drive. A drive motor 2 is fixedly mounted on the top of the reducer housing 1. The power shaft 21 of the drive motor 2 is arranged perpendicularly to the output shaft 11. Thus, this embodiment forms a vertical spatial arrangement, which can be arranged in a relatively narrow space between the power equipment 9 and the triangular track 8, with low space requirements.

[0018] An intermediate reduction shaft 12 is rotatably mounted inside the reducer housing 1, located between the power shaft 21 and the output shaft 11. A reduction gear set 13 is provided between the intermediate reduction shaft 12 and the output shaft 11. The intermediate reduction shaft 12 is parallel to the output shaft 11. First-stage reduction is achieved through the reduction gear set 13, which can be implemented using spur gears or helical gears, etc., without limitation.

[0019] A reduction bevel gear set 14 is provided between the power shaft 21 and the intermediate reduction shaft 12. The reduction bevel gear set 14 achieves first-stage reduction and together with the reduction column gear set 13, forms two-stage reduction, increasing the transmission ratio and realizing high torque output at the output shaft 11.

[0020] Preferably, an input shaft 15 is rotatably mounted on the top of the reducer housing 1. The input shaft 15 is arranged parallel to the power shaft 21. A first-stage reduction gear set 16 is provided between the power shaft 21 and the input shaft 15, and a reduction bevel gear set 14 is provided between the input shaft 15 and the intermediate reduction shaft 12. Thus, a total of three reduction stages are formed within the reducer housing 1, further increasing the torque output at the output shaft 11. The first-stage reduction gear set 16 can be implemented using spur gears or helical gears, etc., without limitation.

[0021] In addition to the above-described structural principle, this embodiment, due to the inclined arrangement of the reducer housing 1, can only be filled with a fixed amount of oil at the bottom. During operation, the rotation of the gears on the output shaft 11 generates a swirl motion, causing the oil to be thrown up. The oil then cools and lubricates other gears with relatively small height differences along the inclined housing wall. This satisfies the cooling and lubrication requirements within the reducer housing 1 while preventing oil from seeping into the drive motor 2, ensuring long-term reliable operation. More preferably, the power shaft 21 is located above the input shaft 15 to further prevent oil from seeping into the drive motor 2.

[0022] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
