Description

Technical Field

[0001] This utility model belongs to the technical field of transmission machinery devices, and relates to a transition gearbox for vehicles. Background Technology

[0002] Currently, large vehicles such as RVs and buses are difficult and troublesome to load and unload due to their high chassis height. In addition, the gearboxes that connect the engine and the rear axle assembly at both ends of these large vehicles have poor heat dissipation. The gearboxes will inevitably generate high temperatures during transmission. If the high temperature heat is not dissipated in time, the wear and tear on the components will increase significantly, affecting normal use. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a vehicle transition gearbox with a lower chassis and efficient heat dissipation function.

[0004] The objective of this utility model can be achieved through the following technical solution: A vehicle transition gearbox includes a housing and a cover connected to each other, with a transmission zone formed inside the housing and the cover, and both the housing and the cover having a transmission groove. The housing is characterized by having an input shaft that is linked to the engine, and an output shaft that is linked to the rear axle assembly, on the cover. The input shaft and the output shaft are not on the same axis. Both the housing and the cover have heat dissipation cavity structures for cooling the transmission zone and the transmission groove. The housing has an inlet and an outlet that communicate with the heat dissipation cavity structures.

[0005] In the aforementioned automotive transition gearbox, the heat dissipation cavity structure includes a heat dissipation and water-proof cavity hollowed out in the housing and the cover, and the housing and the cover are respectively provided with an inlet cavity and an outlet cavity that communicate with the corresponding heat dissipation and water-proof cavity. The inlet cavity is connected to the inlet end on the housing, and the outlet cavity is connected to the outlet end on the housing.

[0006] In the aforementioned vehicle transition gearbox, both the inlet and outlet water ends are connected to the engine via water pipes.

[0007] Compared with existing technologies, this vehicle transition gearbox integrates the heat dissipation structure into the gearbox body and cover, and utilizes the engine's built-in cooling system to achieve a cold water cooling circulation system, ensuring the continuity and stability of heat dissipation. Furthermore, it utilizes the height difference between the input and output shafts to lower the chassis and facilitate loading and unloading. Overall, it has the advantages of good heat dissipation and improved product lifespan. Attached Figure Description

Detailed Implementation

[0015] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0016] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, this vehicle transition gearbox includes a housing 1 and a cover 2 connected to each other. A transmission zone 3 is formed inside the housing 1 and cover 2, and both housing 1 and cover 2 have transmission grooves 4. A transmission device consisting of bearings, transmission gears, and other components is installed in the transmission grooves 4. An input shaft 5, which is linked to the engine, is mounted inside the housing 1. An output shaft 6, which is linked to the rear axle assembly, is mounted on the cover 2. The input shaft 5 and output shaft 6 are not on the same axis, forming a height difference between them. By lowering the shaft core of the output shaft 6, the rear axle assembly that is linked to the output shaft 6 is lowered. The height is low, thus reducing the overall chassis height of the vehicle body, making it easier for users to load and unload items. Both the box body 1 and the box cover 2 are provided with heat dissipation cavity structures for heat dissipation of the transmission area 3 and the transmission groove 4. The box body 1 has a water inlet end 7 and a water outlet end 8 that communicate with the heat dissipation cavity structure. The heat dissipation cavity structure includes a heat dissipation water-proof cavity 9 that is hollowed out in the box body 1 and the box cover 2. The box body 1 and the box cover 2 are respectively provided with a water inlet cavity 10 and a water outlet cavity 11 that communicate with the corresponding heat dissipation water-proof cavity 9. The water inlet cavity 10 is connected to the water inlet end 7 on the box body 1, and the water outlet cavity 11 is connected to the water outlet end 8 on the box body 1.

[0017] To elaborate further, both the inlet 7 and outlet 8 are connected to the engine's cooling system via water pipes. The engine's cooling system is one of the key components of the engine. The applicant uses the coolant in the cooling system to be introduced into the heat dissipation water-insulating chambers 9 in the housing 1 and the cover 2 through the inlet 7 to cool the high-temperature transmission area 3, especially the transmission groove 4 where the transmission device is assembled, thus removing the heat. The coolant is then discharged back into the cooling system through the outlet 8, forming a water-cooling cycle.

[0018] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0019] Although this document frequently uses terms such as housing 1, housing cover 2, transmission zone 3, transmission groove 4, input shaft 5, output shaft 6, water inlet 7, water outlet 8, heat dissipation and water-proof cavity 9, water inlet cavity 10, and water outlet cavity 11, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
