AI Technical Summary

Technical Problem

The loader gearbox without a synchronizer results in an unsmooth shifting process and cannot meet the requirements for high torque transmission and low-cost maintenance.

Method used

A synchronizerless shift fork shifting mechanism for a loader gearbox was designed. By setting a spring structure between the gear ring and the sliding sleeve, the spring buffer absorbs the shifting impact and achieves smooth engagement between the sliding sleeve and the gear ring.

Benefits of technology

It achieves smooth gear shifting, reduces shift shock, and maintains a simple structure, low cost, and reliable operation.

Claims

1. A loader gearbox shifting mechanism without synchronizer forks, comprising a first corresponding gear (1), a sliding sleeve (4), a connecting shaft (5), a second corresponding gear (6), and a sliding bushing (7); the first corresponding gear (1) and the second corresponding gear (6) are connected to the connecting shaft (5) via the sliding bushing (7), allowing the corresponding gear and the connecting shaft (5) to rotate relatively independently; the sliding sleeve (4), having internal teeth, is splined and can slide left and right in the middle of the connecting shaft (5); characterized in that, It also includes a spring (2) and a gear ring (3); the gear ring (3) with external teeth is connected to the corresponding gear one (1) and the corresponding gear two (6) by splines, so that there is no relative rotation between the gear ring (3) and the corresponding gear; the spring (2) is installed between the gear ring (3) and the corresponding gear.
