Locking device for gearshift shafts of conjoined rear axle gearbox

Abstract

The invention discloses a locking device for gearshift shafts of a conjoined rear axle gearbox. The locking device comprises three gearshift shafts, namely a low-gear shift shaft, a middle-gear shift shaft and a high-gear shift shaft, arranged on a gearbox body; a plurality of groups of grooves are respectively formed in the same positions of the same ends of the three shift shafts; a locking shaft is sleeved outside the end of the middle-gear shift shaft, where the grooves are formed; steel balls I and steel balls II are arranged in the locking shaft; steel balls II are respectively arranged between the locking shaft and the low-gear shift shaft and between the locking shaft and the high-gear shift shaft; the steel balls II, a compression spring and screws are sequentially arranged on one side of the locking shaft; all the steel balls II and the steel balls I are positioned on the same section; the locking shaft is connected with a separating pull plate of a clutch through a linking mechanism. According to the locking device for the gearshift shafts of the conjoined rear axle gearbox, which is disclosed by the invention, the out-of-gear phenomenon during driving of vehicles is avoided and the mechanical safety and reliability during driving are improved.

Description

technical field [0001] The invention relates to a gear shift fork shaft locking device of a conjoined rear axle gearbox. Background technique [0002] At present, the locking of the shift fork shaft of the rear axle gearbox in China mostly adopts the structural form of the compression spring directly pressing down the positioning steel ball to tighten the shift fork shaft. Although the purpose of gear position positioning can be achieved, in the actual driving process Sometimes it will be out of gear, especially when driving on a steep and uneven road, which will affect driving safety, not only increase the trouble of driving the vehicle, but also cause loss of life and property in severe cases. Contents of the invention [0003] In order to solve the above problems, the present invention provides a gear shift fork shaft locking device for a conjoined rear axle gearbox, which ensures that the gear will not be automatically disengaged during driving, and improves the mechan...
