Run-through shaft assembly capable of realizing power separation

Abstract

The invention discloses a run-through shaft assembly capable of realizing power separation, and relates to the field of automobiles. The run-through shaft assembly comprises an output shaft and a rearcover bearing pedestal, and further comprises a first bearing, a differential lock with a shifting fork, a sliding mesh sleeve, a second bearing, a gasket, a locknut and an output flange; a spline ofthe output shaft is arranged in a rear axle shaft gear; the first bearing is arranged between the output shaft and a rear cover bearing pedestal; the second bearing is arranged between the output shaft and the output flange; the sliding mesh sleeve is connected with the output shaft and the output flange through the spline; an oil seal is arranged between the output flange and the rear cover bearing pedestal; the differential lock with the shifting fork is mounted on the rear cover bearing pedestal; the output shaft is separated from the output flange; and the differential lock with the shifting fork controls the movement of the sliding mesh sleeve to realize the connection and disconnection between the output shaft and the output flange to control the connection and disconnection of power to a rear axle. The problems that an existing run-through shaft assembly cannot control the connection and disconnection of the power to the rear axle and a run-through shaft structure is poor in bearing capability and inconvenient in after-sales repair are solved.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to an axle through shaft assembly for a vehicle driven by double axles. Background technique [0002] At present, common truck drive forms include single-axle drive and double-axle drive. Single-axle drive is suitable for general light and medium-sized trucks; double-axle drive is suitable for most long-distance heavy-duty vehicles to meet the driving force when loading. For one-way loading, double-axle driven vehicles that return empty-loaded, the driving force is surplus during the return journey, such as oil tank trucks, powder logistics vehicles, coal trucks, sprinklers, garbage trucks, etc., and 6×4 tractors are required for loading Provide sufficient load-bearing drive capacity. If the vehicle is lightly loaded and returns in the 6×4 driving mode, since the double-axle drive has many parts involved in power transmission, the transmission efficiency of the wh...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a power-separatable through-shaft assembly, which can solve the problem that the existing through-shaft assembly cannot control the on-off of power to the rear axle, the relatively poor bearing capacity of the through-shaft structure and the after-sales problem. Inconvenient maintenance and many other problems
