Description

TECHNICAL FIELD

[0001] The utility model relates to the field of gearbox, especially a gearbox assembly and a vehicle. BACKGROUND

[0002] The dump truck is the main vehicle type in the fields of mine, water conservancy, port and wharf, and undertakes heavy material transportation task. However, its working environment is harsh, and it often needs to run on soft, pitted and muddy ground. Such complex working conditions put high requirements on the performance and reliability of each part of the vehicle. As the core component of mechanical transmission or hydraulic transmission, the stability of the gearbox is crucial.

[0003] The gearbox plays a key role in the transmission system of such engineering vehicles, which transmits the torque output by the engine to the transmission shaft and then to the drive axle, realizing the stable walking of the whole machine. In order to ensure the normal operation of the gearbox, sufficient oil level and clean oil are essential. The oil not only plays a lubricating role to reduce the wear of gears and other components, but also helps to dissipate heat and maintain the gearbox working at an appropriate temperature. Once the oil level is insufficient or the oil is contaminated, the internal components of the gearbox will wear out more quickly, the service life will be greatly shortened, and in severe cases, it may even cause work failure, resulting in vehicle downtime and affecting the entire engineering progress.

[0004] Therefore, regular accurate measurement of the oil level of the gearbox and control within the appropriate range, as well as regular replacement of the filter element to ensure the cleanliness of the oil, have become key links in vehicle maintenance. In actual operation scenes such as mine areas, in order to strictly control the stable operation of the equipment, the oil level of the gearbox is checked once every 10 hours (i.e. shift time), and the number of daily checks can reach 2-3 times.

[0005] However, the existing oil filler pipe and oil gauge structure of the gearbox has many drawbacks. The oil filler port is located in the middle and lower part of the side of the gearbox, and the gearbox is usually arranged inside the whole machine. When the driver checks the oil level every shift, he needs to open the hood and stand on the walkway to operate with a bent back, and then he can pull out the oil gauge to observe the oil level. This process is extremely inconvenient, labor-intensive, and greatly hinders the daily detection and maintenance of the gearbox. In addition, the maintenance of the gearbox filter is also a problem. The filter element needs to be replaced every 1000 hours, but its position is at the lower part of the gearbox. The maintenance personnel have to drill into the vehicle bottom to replace the filter element after removing the filter. This operation is not only cumbersome and extremely inconvenient, but also in the narrow space of the vehicle bottom, a little carelessness can easily damage the filter, reducing the reliability of the filter and affecting the overall performance of the gearbox.

Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0025] Example 1

[0026] like Figure 1 As shown, a transmission assembly includes a transmission body 1. The transmission body 1 has a housing oil inlet 10 and a filter mounting base 11. A first extended oil pipe 12 is installed on the housing oil inlet 10. One end of the first extended oil pipe 12 is connected to the housing oil inlet 10, and the other end of the first extended oil pipe 12 extends upward. An extended dipstick 9 is installed in the first extended oil pipe 12. The extended dipstick 9 extends into the interior of the transmission body 1. The oil filler is guided to the outside of the engine cover through the first extended oil pipe. The operator can pull out the dipstick while standing on the platform without having to open the engine cover each time, greatly improving the convenience of operation. Figure 2 The first extended oil pipe 12 includes a lower vertical section 121 and an upper vertical section 123. An inclined section 122 is provided between the lower vertical section 121 and the upper vertical section 123. The inclined section 122 is inclined upwards and away from the gearbox body 1. Further, a gearbox mount 6 is installed on the gearbox body 1. The gearbox mount 6 includes a flat plate and a vertical plate. The vertical plate is fixedly connected to the gearbox body 1. The housing oil inlet 10 is located below the vertical plate. The lower part of the first extended oil pipe 12 is located inside the vertical plate. A first oil pipe bracket 4 is installed on the flat plate. The upper end of the first oil pipe bracket 4 is clamped by a first pipe clamp 5.

[0027] The filter mounting base 11 is provided with a filter connecting pipe. One end of the filter connecting pipe is connected to the oil port on the filter mounting base 11, and the other end of the filter connecting pipe is connected to the filter 3. Specifically, the filter connecting pipe includes an oil inlet pipe 7 and an oil return pipe 2. One end of the oil inlet pipe 7 is connected to the oil outlet of the filter mounting base 11, and the other end of the oil inlet pipe 7 is connected to the oil inlet of the filter 3. One end of the oil return pipe 2 is connected to the oil return port of the filter mounting base 11, and the other end of the oil return pipe 2 is connected to the oil outlet of the filter. The filter connecting pipe is equipped with a second pipe clamp 13, which simultaneously clamps the oil inlet pipe 7 and the oil return pipe 2; the filter connecting pipe is also equipped with a third pipe clamp 8, which is connected to a second oil pipe bracket 14. The end of the filter connecting pipe near the filter 3 is equipped with a pipe clamp 15, which simultaneously clamps the oil inlet pipe 7 and the oil return pipe 2.

This enables the operator to conveniently carry out work by standing on the walkway, and the oil level gauge inspection and oil level measurement can be easily completed without opening the engine cover, greatly improving the operation convenience and reducing the fatigue of the operator. The filter connecting pipe sets the oil filter outside the vehicle, and a pipe clamp is arranged at the end close to the filter, so that the filter element replacement work becomes more convenient. During vehicle maintenance, the internal structure of the vehicle frame does not need to be disassembled, the operation difficulty is reduced, the time cost is reduced, and the maintenance efficiency and safety are significantly improved. The first oil pipe support and the first pipe clamp are installed by using the gearbox suspension, which can stably support the first lengthened oil pipe. Even if the vehicle is running on complex road conditions, the oil pipe can remain in a stable state, avoiding loosening and oil leakage due to vibration. The vertical plate plays a protective role on the lower part of the first lengthened oil pipe, effectively preventing the impact of road splashes. The second pipe clamp ensures that the oil inlet pipe and the oil return pipe maintain a relatively stable positional relationship during vehicle operation. The third pipe clamp and the second oil pipe support provide additional support for the filter connecting pipe, preventing it from deforming and damaging due to uneven stress, thereby improving the structural stability of the entire system. The oil inlet pipe and the oil return pipe jointly construct an efficient filter oil circuit circulation system, enabling the filter to efficiently purify the oil and remove impurities, thereby prolonging the service life of the gearbox oil and ensuring the normal operation of the gearbox components. This helps to reduce the wear and failure rate caused by oil pollution and improves the overall performance and durability of the gearbox assembly. At the same time, the reasonable structure layout saves the internal space of the vehicle, creates favorable conditions for the reasonable arrangement of other components, and improves the compactness and rationality of the overall structure of the vehicle.
