Abstract
The utility model discloses a transfer case for realizing the dynamic allocation of the torsional moment of the front and rear shafts of a four-wheel-drive vehicle, which is characterized in that the transfer case is added with a viscous coupling, a gear box is connected with the viscous coupling through the drive, and the viscous coupling distributes the power to the front and rear axles. As the transfer case provided in the utility model is added with the viscous coupling, the gear box is connected with the viscous coupling through the drive and the viscous coupling distributes the power to the front and rear axles, the viscous coupling can automatically distribute the torque moment to the front and rear drive wheels. The torsional moment can be implemented the dynamic allocation, which distributes most of torsional moment to the drive wheel with the large adhesive force in order to avoid the slippage of the drive wheel.
Description
Technical field
The utility model relates to four-wheel driven car power train manufacturing technology field, relates to the transfer case that can carry out dynamic assignment in a kind of four-wheel driven car power train to moment of torsion in particular.
Technical background
Usually go-anywhere vehicle is provided with set of gears mechanism in transfer case, is used for distributing the moment of torsion of antero posterior axis, realizes four-wheel drive.Shortcoming is that the transmission system part is many, and mechanical wear is big, meshed transmission gear galloping, and noise is big, because gear is by the fixed drive ratio transmission, so moment of torsion also is to be assigned to antero posterior axis by fixed proportion, can not distribute the moment of torsion of antero posterior axis dynamically.The rotating speed that makes front driving wheel and rear drive sprocket when the driving wheel adhesion difference of four-wheel driven car needs moment of torsion to carry out dynamic assignment not simultaneously, with most of torque distribution to the big driving wheel of adhesion.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of transfer case of dynamic assignment of the moment of torsion of realizing the four-wheel driven car antero posterior axis
The technical solution of the utility model is to have set up viscous coupling in transfer case, the gearbox viscous coupling that is in transmission connection, and viscous coupling is back axle dynamic assignment power forward.
Above-mentioned viscous coupling shaft drive connection backward is to realize by a pair of hypoid gear that connection is located in the transfer case, the shell of viscous coupling connects the gear ring of hypoid gear, the gear ring gear shaft, gear shaft arrives back driving axle with power transmission.
The interior hub connection of viscous coupling is arranged on front axle differential in the transfer case, and front axle differential is with the power transmission front driving wheel.
Front axle differential is located on the transfer case.
The utility model has been owing to set up viscous coupling now in transfer case, the gearbox viscous coupling that is in transmission connection, and viscous coupling is the back axle distributed power forward.The viscosity shaft joint can be given the front and back driving wheel according to the automatic distribution of torque of the situation of front and back wheels.Moment of torsion can be carried out dynamic assignment, with most of torque distribution to the big driving wheel of adhesion.Thereby avoid driving wheel to skid.
