Abstract

The invention relates to a power drive device for a multi-axle vehicle. A transfer case drive shaft and a transfer case driven shaft are arranged in a transfer case; the transfer case drive shaft is connected with a front drive axle; the transfer case driven shaft is connected with an intermediate drive axle; power transferred from an engine is directly transferred to the front drive axle through transmission parts and the transfer case drive shaft; and through the operation of the engagement or the separation of the drive components in the transfer case, the power is transferred to the transfer case driven shaft from the transfer case drive shaft so as to realize the switch of using states of the intermediate using state. The power drive device is also provided with a second transfer case; a second transfer case drive shaft and a second transfer case driven shaft are arranged in the second transfer case; the second transfer case driven shaft is connected with a rear drive axle; the intermediate drive axle is connected with the second transfer case drive shaft through the transmission parts; and through the operation of the engagement or the separation of the transmission components in the second transfer case, the power is transferred to the second transfer case driven shaft from the second transfer case drive shaft so as to realize the switch of the using states of the rear drive axle. The power drive device is reasonably designed, simple to operate and convenient to switch drive axles.

Description

technical field [0001] The invention relates to a vehicle transmission device with a transfer case for driving front and rear wheels, especially a power transmission device for a multi-axle vehicle. Background technique [0002] We know that multi-axle vehicles can switch between multiple drive axles through joysticks or buttons to obtain ideal traction according to road conditions and fuel consumption. When a multi-axle vehicle is carrying out multi-axle power transmission, the transmission device is also different due to the difference of the vehicle. CN201553025U Chinese Utility Model Patent Specification, which was applied for by the applicant and authorized and announced on August 18, 2010, discloses a "multi-axle power transmission device for automobiles". Connection, the main transmission shaft is connected to one end of the drive shaft of the transfer case through a universal joint, the side of the drive shaft of the transfer case is provided with the driven shaft o...
