Rear steering drive axle assembly of forklift

Abstract

The invention relates to a rear steering drive axle mechanism and discloses a rear steering drive axle assembly of a forklift, comprising an axle body assembly (1). The axle body assembly (1) is fitted with a main reducer (2), two sides of the axle body assembly (1) are provided respectively with left and right axle shaft assemblies (41 and 42) connected with left and right hubs (31 and 32), a differential lock (5) is fitted inside the main reducer (1), and the differential lock (5) is connected with the left and right axle shaft assemblies (41 and 42) through splines; both ends of the left and right axle shaft assemblies (41 and 42) are connected with wheel reduction mechanisms (6) through splines. Four drive performance of the forklift is implemented through the rear steering axle that is provided with drive, off-road performance, driving capacity and gradeability of the forklift are improved, and work efficiency is finally improved; the differential lock with a slide limiting function is disposed in the main reducer, the axle shaft of the side wheel that slides is locked to achieve freeing when the tires of the forklift get trapped in sandy land and mire.

Description

technical field [0001] The invention relates to a rear steering drive axle mechanism, in particular to a transmission structure of a rear steering drive axle of an off-road forklift. Background technique [0002] The current forklift rear steering drive axle assembly is generally a steering axle without drive. The differential lock of the main reducer of the bridge has no limited-slip self-locking function. When the left and right wheels fall into sand or mud, there will be a differential phenomenon. Contents of the invention [0003] The invention provides a forklift rear steering drive axle assembly aiming at the forklift's off-road performance, driving force, climbing ability, anti-slip and escape ability, etc. in the prior art. [0004] In order to solve the above technical problems, the present invention is solved through the following technical solutions: [0005] The rear steering drive axle assembly of the forklift includes the axle body assembly, on which the ma...

AI Technical Summary

Problems solved by technology

[0002] The current forklift rear steering drive axle assembly is generally a steering axle without drive. The main reducer differential lock of the bridge has no limited-slip self-locking function. When the left and right wheels fall into sand or mud, there will be a differential phenomenon. The torque input by the main reducer is transmitted to the slipping wheels, and high-speed rotation occurs, making it impossible to get out of trouble.
