Problems solved by technology

In the two-drive mode, the input gear on the input shaft will rotate together with it, and the output shaft and the parts on the output shaft will idle under the drive of the input gear, which will not only cause a large energy loss in the transfer case , and when these components are always in an idling state, it will lead to a decrease in the NVH (Noise, Vibration, Harshness, noise, vibration and harshness) performance of the vehicle

Embodiment 1

[0030] Such as figure 1 As shown, the unipolar transfer case 100 includes a first shaft 110 and a second shaft 120 perpendicular to the first shaft 110. The left and right ends of the first shaft 110 are respectively provided with first bearings 111 (as shown in the figure Shown cone bearing), the first shaft 110 between the left and right first bearings 111 is rotatably provided with a first gear 112 (bevel gear) through a needle bearing, the first gear 112 and the first bearing at the right end A clutch is fixedly connected between 111, the input end of the clutch is connected to the first shaft 110, and the output end is connected to the first gear 112, and the clutch is used to engage or disconnect the power transmission between the first shaft 110 and the first gear 112; The second shaft 120 is provided with a second gear 121 (bevel gear), a second bearing 122 (a ball bearing as shown in the figure), the first gear 112 meshes with the second gear 121, and the first shaft ...

Embodiment 3

[0049] The present invention also provides a power assembly, including an engine, a transmission, a transfer case, and a drive axle. The output end of the engine is connected to the input end of the transmission, and the output end of the transmission is connected to the input end of the transfer case. The output end is connected to the drive bridge, wherein, since the transfer device has been described in detail in the above embodiments, it will not be repeated here.

Abstract

The invention discloses a power divider and a power assembly, relates to the technical field of automobile power assemblies and is used for reducing energy loss of the power divider and improving integral noise, vibration and harshness (NVH) performance. The power divider comprises a first shaft and a second shaft, wherein the first shaft or the second shaft is used for being connected with a power output end of a transmission, a first gear is sleeved on the first shaft rotatably, a second gear is fixed on the second shaft, the first gear is meshed with the second gear, a clutch is arranged on the first shaft, an input end of the clutch is connected with the first shaft, an output end of the clutch is connected with the first gear, and the clutch is used for connecting or disconnecting power transfer between the first shaft and the first gear.

Description

technical field [0001] The invention relates to the technical field of automobile power assembly, in particular to a transfer case and a power assembly. Background technique [0002] At present, the driving modes of four-wheel drive SUVs are divided into full-time four-wheel drive, part-time four-wheel drive and timely four-wheel drive. For timely four-wheel drive, it can identify the driving environment by itself, and control the two-wheel drive and four-wheel drive according to the changes in the driving environment. The switch between the two modes has superior fuel-saving performance and driving performance, so it is favored by many four-wheel drive fans. Among them, the four-wheel drive mode is realized through the transfer case. The mechanical transmission part of the transfer box is a gear transmission system, which is fixed on the frame. Its input shaft is directly connected to the output shaft of the transmission, and there are several output shafts, and the output...
