Description

Technical Field

[0001] The utility model relates to the technical field of transfer cases, in particular to a four-wheel drive transfer case motor assembly. 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 a transfer case of different styles, matching four-wheel drive vehicles with different demands. Their basic principles and functions are also different. A part-time four-wheel drive vehicle is a car that can be a two-wheel drive vehicle at ordinary times and a four-wheel drive vehicle in off-road conditions. The part-time four-wheel drive transfer case is a purely mechanical device. When the transfer case of this structure is in 4WD mode, the front and rear axles are rigidly connected, which can achieve a 50:50 distribution of front and rear power, which is very beneficial to improving the vehicle's passability. In addition, due to its purely mechanical structure, it has high reliability, which is crucial for models that often travel in wilderness where there is a lack of rescue. Even now, there are still a large number of hard-core off-road vehicles that use this transfer case. On the transfer case lever of this type of vehicle, we will see 2H, 4H, N, and 4L switching gears. When the 2H gear is engaged, this type of vehicle is a rear-wheel drive vehicle. The power of the engine passes through the gearbox and is directly connected to the rear axle through a drive shaft. The function of the transfer case is to lead out an output end on the gearbox and transmit the power to the output shaft of the front axle through a silent chain. Of course, this is not a direct connection, otherwise it would be impossible to switch between 4WD and 2WD. In fact, it is separated and connected through two sets of gears, and its structure and principle are similar to the first and second shafts of the gearbox. When switching, pull the shift lever of the transfer case to connect and disconnect the power to the front drive shaft through the shift fork. Unlike the mainstream gearbox with synchronizer, the switching of this part does not have a synchronizer, and it requires a complete match between the speed and the wheel speed. This is the basic principle of this transfer case.

[0003] The application number is CN201720819539.9, which discloses an intelligent four-wheel drive hybrid system, including a front axle drive assembly, a rear axle drive assembly and a motor controller, wherein the front axle drive assembly includes a BSG motor, an engine and a gearbox, and the rear axle drive assembly includes a rear drive motor and a rear axle second-speed gearbox, and the BSG motor and the rear drive motor are both connected to the motor controller. The intelligent four-wheel drive hybrid system can be divided into four power modes according to the power structure, and can be divided into fifteen modes according to the driving conditions, which improves the intelligent four-wheel drive hybrid control, realizes vehicle energy balance and smooth driving, and realizes the effect of sufficient vehicle power and reduced fuel consumption.

[0004] Although the above-mentioned utility model can be divided into four power modes according to the power structure and fifteen modes according to the driving conditions, it improves the intelligent four-wheel drive hybrid control, realizes the vehicle energy balance and smooth driving, and realizes the effect of sufficient vehicle power and reduced fuel consumption. However, there is a shortcoming that when the device is transmitting power, it cannot perform emergency braking and emergency stopping when encountering sudden situations. As a result, when the car brakes, the braking method is relatively single and cannot meet emergency situations.

[0005] Therefore, it is necessary to add an emergency brake component to the device so that if any unexpected situation occurs during use, emergency braking can be used to help stop power transmission. Utility Model Content
