Abstract

The invention relates to an ultra-long drive shaft and a preparation method thereof, and belongs to the drive shaft technology. The shaft includes a chassis frame, a super-long drive shaft assembly isarrange at that bottom end of the chassis frame, the side of the super-long drive shaft assembly is provided with a plurality of drive axles movably contacting with the super-long drive shaft assembly, the super-long drive shaft assembly include a drive shaft, a plurality of support frames sleeved with the drive shaft are arranged between the drive shaft and the chassis frame, bevel gears I sleeved with the drive shaft are arranged at the middle and the end of the drive shaft, the bevel gears I mesh with the drive axle, a fixed plate fixed with the chassis frame is arranged at the upper end of the cushion damping part, and a bearing seat movably sleeved with the drive shaft is arranged at the lower end of the cushion damping part. The super-long driving shaft has the characteristics of simple structure, large torque, labor-saving driving and long service period, and improves the stability and maneuverability in the running process of the vehicle. The preparation method solves the problems of disturbance deformation, shaft runout, shear stress overload and short service period, and reduces the processing cost.

Description

technical field [0001] The invention relates to the technical field of drive shafts, in particular to an ultra-long drive shaft and a preparation method thereof. Background technique [0002] When we start the truck, the engine will generate power and transmit the power to the gearbox. The power will pass through the gears in the gearbox to convert the high-speed low-torque power into low-speed high-torque power, and then transmit it to the drive rear axle through the drive shaft. The driving rear axle drives the driving rear wheels to rotate, so a car moves. Small trucks generally use front-engine front-wheel drive, and large trucks use front-end rear drive. When the load is heavy, the vehicle consumes too much power, and the driving stability is poor. [0003] The disadvantage of front-wheel drive is: because the front wheel is responsible for both driving the vehicle and steering the vehicle, the front axle is overloaded, which makes the front center of gravity of the fr...
