Tractor front drive axle provided with cylindrical helix gear-type limited slip differential

Abstract

The invention discloses a tractor front drive axle provided with a cylindrical helix gear-type limited slip differential, belonging to the technical field of tractor parts. The tractor front drive axle structurally comprises a main speed reduction box assembly, a left half axle shell, a left tail end transmission case assembly, a right half axle shell and a right tail end transmission case assembly; the left end of the main speed reduction case assembly is connected with the left half axle shell; a left half axle is arranged in the left half axle shell; the left end of the left half axle shell is connected with the left tail end transmission case assembly through a connection cover; the right end of the main speed reduction box assembly is connected with the right half axle shell; a right half axle is arranged in the right half axle shell; and the right end of the right half axle shell is connected with the right tail end transmission case assembly through a connection cover. By adopting the tractor front drive axle, a large limited slip capability can be provided, so that the passing capability and use performance of the whole axle under severe working conditions are improved; the universality of parts is improved, so that the production cost of the whole axle is controlled, and requirements of operation of a tractor under different working conditions are met; and the use performance and reliability of the tractor front drive axle are further improved.

Description

technical field [0001] The invention relates to the technical field of tractor accessories, in particular to a tractor front drive axle with a cylindrical helical tooth type limited-slip differential. Background technique [0002] The differential is an important part of the drive axle. Its main function is to make the left and right drive wheels of the drive axle have the differential speed required by driving kinematics, and distribute the power to the left and right drive wheels. When the tractor is turning , if there is no differential between the left and right drive wheels, or if the differential is completely locked, then according to kinematic requirements, the long-travel outer wheel will be accompanied by slip, while the short-travel inner wheel will slip. Accompanied by slippage. As a result, an additional resistance is respectively produced in the tangential direction of the left and right driving wheels, and their acting directions are opposite. At this time, ...
