Problems solved by technology

At present, the steering drive of domestic crawler vehicles mostly adopts the clutch steering system. The main disadvantage of the clutch steering system is that during the steering process, the power is all concentrated on one side of the vehicle while the other side has no power. On the one hand, the device greatly affects the driving force of the engine, reduces the transmission efficiency, causes waste of power energy, affects the operating efficiency and construction progress of the tracked vehicle, and prolongs the construction time; on the other hand, it causes the tracked vehicle to turn unstable
In addition, this clutch steering cannot realize the in-situ steering of the tracked vehicle, and the work flexibility is not high
[0003] The patent number is 4,700,794, and the invention name is "vehicle steering gear". For use on vehicles, not for use in small and medium vehicles
The patent number is 5,535,840, and the invention title is "Steering System for Tracked Vehicles". The main disadvantage of the tracked vehicle steering system is that the transmission ratio is small when driving in a straight line, which increases the transmission ratio of other components of the tracked vehicle. It increases the design difficulty of tracked vehicles, and the structure is more complicate

Abstract

The invention relates to a turning driving device of crawler vehicle. Power output shaft connected with small gear is set in box body and the big gear on the shaft is mated with the small gear. The shaft is hollow. Small and big gears are cylinder gear. On the shaft left sun gear mated with left planetary gear connected with the left output shaft, right sun gear mated with right planetary gear connected with the right output shaft are set. Left ring gear connected with left bevel gear is mated with the left planetary gear and right ring gear connected with right bevel gear is mated with the right planetary gear. Left positioner is set on the left output shaft and right positioner is set on the right output shaft. Bearings are set between the left ring gear and the shaft, and between the right ring gear and the shaft. Bearings are set between left shaft sleeve connected with the left ring gear and the body, and between right shaft sleeve connected with the right ring gear and the body. Bearing is set between the left output shaft and the left shaft sleeve and bearing is set between the right output shaft and the right shaft sleeve. Turning control input shaft combined with turning bevel gear together is set on the body. The turning bevel gear is mated with the left bevel gear connected with the left ring gear and the right bevel gear connected with the right ring gear.

Description

technical field [0001] The invention belongs to the technical field of the steering mechanism of non-deflectable wheels; the steering mechanism of crawler belts or similar parts, and in particular relates to the running parts on both sides of the opposite vehicle driven by differential speed with separate power sources. Background technique [0002] With the continuous progress of society, there is an urgent need for a large number of various related medium and small power crawler vehicles in the fields of construction, engineering, agriculture and mining. At present, the steering drive of domestic crawler vehicles mostly adopts the clutch steering system. The main disadvantage of the clutch steering system is that during the steering process, the power is all concentrated on one side of the vehicle while the other side has no power. On the one hand, the device greatly affects the driving force of the engine, reduces the transmission efficiency, causes waste of power energy,...
