Description

Technical Field

[0001] The utility model relates to the technical field of special vehicles, in particular to a power take-off for a new energy transmission. Background Art

[0002] With the continuous development of new energy vehicles, some special operation vehicles are gradually adopting new energy vehicles, such as sprinkler trucks, garbage trucks and other sanitation vehicles. By adopting new energy models, energy can be saved and the effect of energy conservation and emission reduction can be achieved. Therefore, they are widely used in the field of urban environmental operations. For the operation process of sanitation vehicles, it is necessary to take out part of the power from the vehicle's transmission device to be used as power support for operations such as garbage collection and water spraying. Therefore, a power take-off device matching the vehicle's transmission is required.

[0003] The power take-off in the existing technology is an important component of the special vehicle's ability to perform operations and needs to be maintained and serviced in a timely manner. Since construction processes such as garbage collection and loading require large power support, the transmission needs to be cooled and the transmission and speed change accessories inside the power take-off need to be lubricated to ensure long-term and stable operation of the transmission. In addition, due to the need for timely maintenance, there are also high requirements for the convenient disassembly and assembly of the power take-off. For this reason, we propose a power take-off for a new energy transmission. Utility Model Content

[0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide a power take-off for a new energy transmission. The power take-off has a reliable maintenance unit. By unscrewing the oil plug, lubricating oil can be injected into the gear box to lubricate and protect the internal gear set so that the booster can work stably for a long time. When the new energy vehicle is driving, the wind blows along the air inlet to the heat-conducting metal plates on both sides of the gear box, thereby dissipating heat and cooling the gear box. The power take-off has a convenient disassembly and assembly unit, which is convenient for the installation of the various components of the power take-off and is easy to disassemble for inspection and maintenance of the power take-off, ensuring that the vehicle can maintain a good condition, and can effectively solve the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the present utility model provides the following technical solutions: a power take-off for a new energy transmission, comprising a seat plate, a convenient disassembly and assembly unit, and a maintenance unit;

[0006] Seat plate: It is a square plate with rounded corners. A gearbox is installed on the front side of the seat plate, and bearing 2 is embedded in the middle of the seat plate.

[0007] Convenient disassembly and assembly unit: installed at the left and right ends and four corners of the seat plate;

[0008] Maintenance unit: includes an upper mounting seat, an oil plug, a slider, a heat-conducting metal plate and an air inlet. The upper end of the gear box is fixedly connected to a square upper mounting seat, a longitudinal slide groove is provided inside the upper mounting seat, and a slider is slidably connected inside the slide groove. A circular oil filling hole is provided at the upper end of the gear box, and the oil filling hole is upwardly connected to the interior of the upper mounting seat, and an oil plug is threadedly screwed on the oil filling hole. A vertical row of heat-conducting metal plates are fixedly connected in a linear array on the left and right sides of the gear box. A rectangular air inlet is provided at the center position of the left and right ends of the seat plate, and the air inlet and the heat-conducting metal plate are on the same vertical plane.

[0009] The seat plate is used to abut against the transmission housing, so that the power take-off assembly can be installed on the outside of the transmission. The drive shaft is used for the transmission connection between the gearbox and the transmission. The gearbox is used to change the speed transmitted by the drive shaft. The convenient disassembly and assembly unit facilitates the installation of various components of the power take-off and is easy to disassemble for inspection and maintenance of the power take-off; the upper mounting seat is used to seal and protect the oil filling hole at the upper end of the gearbox. The slider can be pulled outward to expose the oil filling hole. By unscrewing the oil plug, lubricating oil can be injected into the gearbox to lubricate and protect the internal gear set so that the booster can work stably for a long time; when the new energy vehicle is driving, the wind blows along the air inlet to the heat-conducting metal plates on both sides of the gearbox, thereby dissipating heat and cooling the gearbox.

[0010] Furthermore, the convenient assembly and disassembly unit includes connecting ears, bolt seats, and hexagon socket bolts. Triangular connecting ears are fixedly connected to both ends of the seat plate. The ends of the connecting ears are rounded, and a circular bolt seat is fixedly connected to the forward side of the connecting ear end. A hexagon socket bolt is installed inside the bolt seat. The threaded section of the hexagon socket bolt passes through the bolt seat and connecting ears in sequence and is threadedly connected to the outside of the transmission. The connecting ears are used to install the bolt seat, and the bolt seat is used to install the hexagon socket bolt. The hexagon socket bolt is used to secure the connecting ears to the transmission housing, thereby securing the seat plate to the outside of the transmission.

[0011] Furthermore, the convenient disassembly and assembly unit further includes a fixing plate, a limiting rod, a nut, and a washer. The rear end of the gearbox is fixedly connected to the fixing plate, and circular through-holes are provided at the four corners of the fixing plate. A vertical limiting rod is fixedly connected to the four corners of the front end of the seat plate. The four limiting rods pass through the through-holes at the four corners of the fixing plate respectively. The outside of the limiting rod is provided with a thread, and a nut is threadedly connected to the outside of each limiting rod. The fixing plate is fixed to the front side of the seat plate by the nut. The fixing plate is used for fixing the gearbox to the seat plate. By aligning the circular through-holes at the four corners of the fixing plate with the limiting rods at the front end of the seat plate, the gearbox and the fixing plate can be plugged and installed to the front side of the seat plate. By screwing the nut, the fixing plate and the seat plate can be fitted and fixed. The washer can deform when the nut is tightened, thereby improving the fastening effect of the fixing plate.

[0012] Furthermore, the convenient assembly and disassembly unit also includes a drive shaft and a rubber pad. A drive shaft passes through the interior of the second bearing, with its rear end connected to the center of the low-speed gear of the transmission. A rubber pad is mounted on the rear side of the seat plate, with slots on both sides reserved for communication with the air inlet. The rubber pad, sandwiched between the seat plate and the transmission, improves the secure installation of the seat plate.

[0013] Furthermore, the maintenance unit also includes a first bearing, an output shaft, and a sealing ring. An annular bearing ring is fixedly connected to the lower front end of the gearbox, with the first bearing mounted inside the ring. The output shaft passes through the first bearing, and its inner end is in driving connection with a gear pair within the gearbox. The sealing ring prevents dust and debris from entering the first bearing, and the first bearing is used to mount the first bearing, which transmits the shifted power outward.

[0014] Furthermore, the maintenance unit includes a lower mounting base and a second oil plug. An oil drain hole is defined at the lower end of the gearbox. An annular lower mounting base is fixedly connected to the interior of the lower mounting base, and the second oil plug is screwed onto the interior of the lower mounting base. The lower mounting base is used to mount the second oil plug, which seals the oil drain hole. When the power take-off requires maintenance, the second oil plug is unscrewed to drain spent lubricating oil and replace it with fresh lubricating oil.
