Description

Technical Field

[0001] The utility model relates to the technical field of transfer cases, in particular to a combined transfer case. Background Art

[0002] The so-called transfer case is a device that distributes the power of the engine. It can output power to the rear axle, or to the front / rear axle at the same time. From this perspective, it can be seen that the transfer case is actually an accessory on a four-wheel drive vehicle. With the development of four-wheel drive technology, the transfer case has been changing, and gradually formed transfer cases of different styles, which are matched on four-wheel drive vehicles with different demands. Their basic principles and functions are also different. The transfer case is a device that distributes the power of the engine. It can output power to the rear axle, or to the front and rear axles at the same time. The characteristic is that for cars with transfer cases, the power is first transmitted to the transfer case by the drive shaft, and then transmitted to the front and rear axles respectively by the transfer case, and can switch between rear-wheel drive and four-wheel drive. It is mostly used in hard-core off-road vehicles.

[0003] In actual use, it is not convenient to cool down the existing combined transfer case, and the temperature of the transfer case is too high, which easily leads to increased wear of parts.

[0004] After searching the existing patents: a transfer case (publication number: CN216478860U), including a housing, a first transmission shaft, a second transmission shaft, a third transmission shaft and a gear-engaging assembly. The housing has an installation cavity, and a brake sleeve is arranged in the installation cavity. A driving gear is connected to the first transmission shaft, and the first transmission shaft and the driving gear rotate synchronously. The second transmission shaft is parallel to the first transmission shaft, and a driven gear meshing with the driving gear is arranged on the second transmission shaft, and the driven gear and the second transmission shaft rotate synchronously. The third transmission shaft and the first transmission shaft are located on the same straight line, and the third transmission shaft runs through the brake sleeve, and a synchronizer is slidably connected to the third transmission shaft. The gear-engaging assembly includes a shifting rod and a shifting fork connected to the shifting rod, and the shifting fork is plugged into the synchronizer. The gear-engaging assembly can drive the synchronizer to move to adjust to any one of the two-wheel drive mode, the four-wheel drive mode and the brake mode. The switching of the three functions of two-wheel drive, four-wheel drive and brake can be achieved by only changing the position of the synchronizer, without the need to set a brake, saving production and installation costs.

[0005] Although the above patent achieves the switching of two-wheel drive, four-wheel drive and brake functions by only changing the position of the synchronizer, without the need for brakes, thus saving production and installation costs, it is not convenient for convenient disassembly and replacement of different combinations of shafts, and reducing installation steps and time.
