Description

Technical Field

[0001] This utility model belongs to the technical field of vehicle transmission components, and relates to an intermediate bridge, particularly a three-axis output intermediate bridge. Background Technology

[0002] The intermediate axle of a vehicle typically refers to the axle located between the front steering axle and the rear drive axle on a three-axle truck or tractor unit. Some heavy-duty or multi-axle special vehicles may have multiple intermediate axles. These intermediate axles usually have both driving and load-bearing functions, and their main purpose is to evenly distribute the enormous vehicle weight and load across more tires and axles, thereby greatly enhancing the vehicle's load-bearing capacity, stability, and traction, while simultaneously meeting stringent road axle load regulations.

[0003] Traditional axles have one input shaft and two output shafts. When there are multiple axles, multiple shafts are set up to drive them separately, which increases the size and weight of the vehicle's transmission unit and requires precise arrangement of the transmission positions. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a small-volume triaxial output intermediate bridge.

[0005] The objective of this utility model can be achieved through the following technical solution: A three-axis output intermediate bridge, characterized in that it includes a housing and a transmission gear, the housing is provided with an end cover, the housing is provided with a differential, the differential is provided with a differential housing, the differential housing is provided with output holes on both sides, the differential housing is provided with a plurality of symmetrically arranged differential gears and output differential teeth, the inner wall of the output differential teeth is provided with a connecting spline, the differential housing is provided with a detachable transmission gear plate, and the housing is provided with two opposing transmission gear shafts.

[0006] In the aforementioned three-axis output intermediate bridge, both the transmission gear shaft and the transmission gear disc are provided with arc-shaped teeth, and the ends of the transmission gear shaft are provided with transmission flanges.

[0007] In the aforementioned three-axis output intermediate bridge, mechanical seals are provided between the output differential gear and the housing.

[0008] In the aforementioned three-axis output intermediate bridge, the differential gear is provided with a limit pin, and the housing is provided with several oil injection bolts.

[0009] Compared with existing technologies, this three-axis output intermediate bridge achieves the result of multiple output ends through a single transmission path by symmetrically setting transmission gear shafts that are consistent with the output ends. It can also combine and connect multiple intermediate bridges to meet different requirements, allowing vehicles to add drive wheels to meet different needs, thus enabling vehicles to adapt to different scenarios. The unit transmission path can reduce the structure of the transmission system, reduce weight and volume, and make vehicle chassis design more diversified. Attached Figure Description

[0014] 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.

[0015] like Figure 1 , 2 As shown in Figure 3, this three-axis output intermediate bridge includes a housing 1 and a transmission gear 7. The housing 1 is provided with an end cover 3. A differential 11 is provided inside the housing 1. A differential housing 9 is provided on the differential 11. Output holes 10 are provided on both sides of the differential housing 9. Several differential gears 14 and output differential gears 16 are symmetrically arranged inside the housing 1 of the differential 11. A connecting spline 15 is provided on the inner wall of the output differential gear 16. A detachable transmission gear disc 5 is provided on the differential housing 9. Two opposing transmission gear shafts 12 are provided on the housing 1. This intermediate bridge is suitable for vehicles with 6 or more axles. Through the two opposing transmission gear shafts 12, one is the input and the other is the output. By combining different numbers of intermediate bridges and interlocking them, vehicles with different numbers of axles can be assembled. The differential 11 transmits power to the output differential gears 16 on both sides. The power transmission is on the same path, reducing the need for multiple transmission shafts and reducing volume and weight.

[0016] Preferably, both the transmission gear shaft 12 and the transmission gear disc 5 are provided with arc-shaped teeth 6, and the end of the transmission gear shaft 12 is provided with a transmission flange 13. The arc-shaped teeth 6 make the transmission smoother and reduce vehicle vibration. The transmission flange 13 can be connected to other intermediate axles or other power components by connecting the transmission shaft, which has a wider range of applications.

[0017] Preferably, a mechanical seal 4 is provided between the output differential gear 16 and the housing 1.

[0018] Preferably, the differential gear 14 is provided with a limit pin 8, and the housing 1 is provided with a number of oil injection bolts 2.

[0019] 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.

[0020] Although this document frequently uses terms such as housing 1, oil filler bolt 2, end cap 3, mechanical seal 4, transmission gear 5, arc-shaped tooth 6, transmission gear 7, limit pin 8, differential housing 9, output hole 10, differential 11, transmission gear shaft 12, transmission flange 13, differential gear 14, connecting spline 15, and output differential tooth 16, 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.
