Transmission rotation torsion buffer shaft

Abstract

Disclosed is a buffer shaft for transmission of rotary torque, the shaft mainly comprising a casing pipe (1), a shaft pipe (2) and a locking element (3), wherein an accommodating space (10) is formed in the casing pipe (1), and a first internal thread (100) and a second internal thread (101) are respectively formed on inner walls of two ends of the casing pipe (1); the shaft pipe (2) is provided in the accommodating space (10), and a threaded portion (20) corresponding to the first internal thread (100) is formed at the middle section of the shaft pipe (2); and the locking element (3) is locked onto the second internal thread (101). The buffer shaft for transmission of rotary torque is mainly applied to large means of transport, such as ships, speed boats, automobiles, etc., and can absorb and balance instantaneous severe rotary torque, thereby reducing a value of linkage mutual deviation torque which is generated during the operation of an engine and a transmission.

Description

technical field [0001] The present invention is a tie rod structure; more specifically, it refers to a car or engine power output, through a gearbox or an automatic transmission, and can connect torsion to a transmission rotating torsion buffer shaft for tire rolling or rotation. Background technique [0002] At present, no matter how the device is installed between the engine and the drive wheel, there must be a complete transmission line between the engine and the drive wheel, so that the power of the engine can be transmitted through the clutch, gearbox, drive shaft, final drive assembly, axle As for the wheels, the wheels rotate to drive the transmission shaft of the vehicle; the damage, wear, deformation and loss of dynamic balance of the transmission shaft parts will cause the car to produce abnormal noise and vibration during driving, and in severe cases will cause damage to related components. And the transmission shaft is a rotating body with high speed and less sup...

Problems solved by technology

[0002] At present, no matter how the device is installed between the engine and the drive wheel, there must be a complete transmission line between the engine and the drive wheel, so that the power of the engine can be transmitted through the clutch, gearbox, drive shaft, final drive assembly, axle As for the wheels, the wheels rotate to drive the transmission shaft of the vehicle; the damage, wear, deformation and loss of dynamic balance of the transmission shaft parts will cause the car to produce abnormal noise and vibration during driving, and in severe cases will cause damage to related components. And the transmission shaft is a rotating body with high speed and less support, so its dynamic balance is very important

[0003] However, when a general vehicle is running, shifting gears or due to the ups and downs of the road surface, it will generate engine power, and will generate a huge differential ratio between the tires, and will cause the transmission speed to be overloaded instantaneously, resulting in uncoordinated motion. The torque value will cause the engine, gearbox, differential and other devices to be easily damaged
