As long as apply certain braking force to brake drum, according to the principle of differential mechanism, can arrive propons to transmission of power during work, if the resistance of front-wheel is greater than the power that is applied to brake drum, then brake drum carries out slippage, can regulate like this variation of front and rear wheel displacement, reduces the wearing and tearing of tire.
A kind of structure of described satellite differential comprises planetary carrier, bevel planet gear and fan tooth, described bevel planet gear is located on the planetary carrier, described fan tooth is installed on respectively on the output shaft of satellite differential two ends, and the both sides fan tooth meshes with bevel planet gear simultaneously.
Described planetary carrier connection teeth wheel drive mechanism.
A kind of structure of described gear drive comprises shift gear, transition gear and driving gear, described shift gear and transition gear are intermeshing, described transition gear and driving gear are intermeshing, described shift gear slides and is located on the power input shaft, and described driving gear is connected with planetary carrier is coaxial.
Described back axle output shaft is coaxial with power input shaft, and the rear end of power input shaft is the output terminal of back axle output shaft.
Advantage of the present invention:
Brake drum differential transfer case of the present invention can make the component of whole transmission system prolong working life, keeps the synchronism of forward and backward four-wheel, reduces the wearing and tearing that tire is brought, and reduces the consume of power, has improved economic benefit.
