As shown in FIG. 1 and FIG. 2, the energy-saving transfer case of the preferred embodiment of the present invention can improve the energy-saving effect of the transfer case and the service life of the transfer case.

Based on the above technical solution, the embodiment provides an energy-saving transfer case, which includes a transfer case 100, a frame 200 and a control module 300, where the frame 200 may be a vehicle frame.

Specifically, the input shaft 110 of the transfer case 100 is provided with a release bearing 400 and a clutch 500, the output end of the clutch 500 abuts against the release bearing 400, the input end of the clutch 500 is connected to the engine, and the transmission of power between the engine and the transfer case 100 can be controlled by the clutch 500.

Specifically, a release fork 210 engaged with the release bearing 400 is mounted on the frame 200, and the release fork 210 can be engaged with the release bearing 400 to control the clutch 500.

Specifically, a separation lever 220 is hinged to the frame 200, one end of the separation lever 220 is hinged to the separation fork 210, the other end of the separation lever 220 is connected to a separation driving assembly 230, and when the separation lever is used, the separation driving assembly 230 can drive the separation fork 210 to rotate, so that the separation lever 220 drives the separation fork 210 to rotate, and the separation fork 210 rotates to control the clutch of the clutch 500.

Specifically, the control module 300 is connected with the CAN bus to acquire engine speed information, the transfer case 100 is provided with a speed sensor 101 and a temperature sensor 102, and the control module 300 is electrically connected with the separation driving assembly 230, the speed sensor 101 and the temperature sensor 102. The temperature sensor 102 is capable of collecting the temperature of the oil inside the transfer case 100.

Specifically, the control module 300 can control the operation of the split drive assembly 230 by collecting engine speed information, transfer case oil temperature, and rotational speed, and thus control the clutching of the clutch 500.

Preferably, the separation driving assembly 230 is a linear stepping motor.

Preferably, the rotation speed sensor 101 is a hall sensor.

Preferably, the control module 300 has a service alert module 310.

The working process of the embodiment is as follows:

1. when the engine speed is 0, the control module 300 controls the declutching drive assembly 230 such that the clutch 500 is disengaged and the transfer case 100 stops operating. The starting of the engine under the condition of 0 load can be realized, and the starting of the engine under the low-temperature and low-pressure environment and the energy conservation in the starting and heating process are facilitated.

2. When the engine speed exceeds the idle speed of the engine by about 100 revolutions (n1), the apparatus is ready to operate. The control module 300 controls the declutch drive assembly 230 to effect engagement of the clutch 500 for an optimum engagement time of the clutch 500 by reading the transfer case 100 input shaft speed via the transfer case 100 speed sensor 101, matching the engine speed. The clutch 500 can be effectively protected from high temperature caused by being in a half-clutch state for a long time, and the service life of the clutch 500 is prolonged.

3. When the engine speed is less than the idle speed of the engine by about 100 revolutions (n2), the device is in a stop state. The control module 300 controls the disconnect drive assembly 230 to disconnect the clutch 500, reads the transfer case 100 input shaft speed via the speed sensor 101 on the transfer case 100, and by matching the engine speed, completely disconnects the clutch 500 to avoid the occurrence of an out-of-position clutch 500 disconnection condition. The clutch 500 can be effectively protected from high temperature caused by being in a half-clutch state for a long time, and the service life of the clutch 500 is prolonged.

4. When the engine speed is less than the idle speed by 100 revolutions (n2), the apparatus is in a standstill state. The control module 300 controls the clutch 500 to disengage, so that power transmission from the engine to the transfer case 100 is interrupted, energy conservation can be effectively achieved, and the service life of hydraulic elements on the output shaft of the transfer case 100 is prolonged.

5. When the temperature of the oil of the transfer case is monitored in real time by the control module 300 through the temperature sensor on the transfer case, and when the temperature of the oil exceeds A ℃, the control module 300 controls the separation driving assembly 230 to separate the clutch 500, so that parts such as sealing parts, bearings and the like in the transfer case 100 are effectively protected.

6. When the temperature of the oil temperature of the transfer case 100 exceeds B ℃, the oil temperature of the transfer case 100 is combined again after the clutch 500 is disengaged, and the oil temperature of the transfer case 100 rises to B ℃ quickly. The maintenance alert module 310 of the control module 300 issues an alarm to prompt for a shutdown check. The internal fault of the transfer case 100 can be predicted in advance, and other losses caused by damage to the transfer case 100 in the running process are avoided.
