Transfer case

Abstract

The invention provides a transfer case. The transfer case comprises an adapter shaft, a transmission mechanism, a clutch C6, a planet carrier, a rear output shaft, a front output shaft and a speed changer. The power output end of the speed changer is connected with the clutch C6 through a middle shaft of the speed changer. A spline of the adapter shaft is further provided with a drive gear of the transmission mechanism. The power output end of the transmission mechanism is connected with the power input end of the planet carrier. The power output end of the planet carrier is connected with the power input end of the rear output shaft and the power input end of the front output shaft. The transfer case and the speed changer are integrally designed, distance reduction is achieved, the vehicle structure is optimized, the full-time four wheel drive of a vehicle is achieved, the passing ability, the climbing capability, the acceleration performance and the like of the vehicle are improved, drive modes can be reasonably selected for the vehicle according to different road surface environments, switching is convenient, control is easy, the driving characteristic of the whole vehicle is improved, and the service life of the whole vehicle is prolonged. The fuel oil efficiency and the economical efficiency of an engine are improved.

Description

technical field [0001] The invention relates to the field of mechanical transmission, in particular to a transfer case. Background technique [0002] With the development of society, people have higher and higher requirements for the road surface adaptability of vehicles, and the demand for large-tonnage off-road vehicles / special vehicles is increasing day by day due to the accelerated industrial development. Off-road vehicles and special vehicles are widely used. Production is becoming more and more large-scale, and vehicle structure is becoming more and more optimized. Compared with existing vehicles, the driving torque cannot be reasonably distributed to the front and rear output shafts, and the driving force and lateral force of each tire cannot be fully utilized, which reduces the driving characteristics and operational stability of the vehicle. Only by rationally distributing the output torque of the front and rear axles can the vehicle adapt to more road conditions a...
