Description
Technical field
The invention belongs to the steering hardware of on-deflectable wheel; The steering hardware technical field of crawler belt or like is specifically related to the ground-engaging element with the relative vehicle both sides of differential driving that separates propulsion source.
Background technology
Along with the continuous progress of society, construction, engineering, agricultural, field, mine be badly in need of large quantities of various relevant in, the miniwatt continuously tracked vehicle.Current, the steer-drive of domestic continuously tracked vehicle adopts the power-transfer clutch steering swivel system more, the major defect that the power-transfer clutch steering swivel system exists is in steering procedure, power all focuses on a side of vehicle when turning to, and opposite side does not then have power, and this steering hardware makes the propulsive effort of driving engine be greatly affected greatly on the one hand, driving efficiency reduces, cause the waste of power source, influenced the operating efficiency and the construction speed of continuously tracked vehicle, prolonged the engineering time; Cause continuously tracked vehicle to turn to instability on the other hand.In addition, this power-transfer clutch turns to the pivot stud that can't realize continuously tracked vehicle, and operation flexibility is not high.
The patent No. is 4,700,794, denomination of invention is the US Patent of " bogie of car ", the major defect of this bogie of car be its gear join the tooth difficulty, require gear that strict drive connection is arranged, next is that structure is not compact, can only use on full size vehicle, can not use in middle-size and small-size vehicle.The patent No. is 5,535,840, denomination of invention is the US Patent of " being applied to the steering swivel system of continuously tracked vehicle ", the major defect of this continuously tracked vehicle steering swivel system is when straight-line travelling, transmitting ratio is less, causes the transmitting ratio of other member of continuously tracked vehicle to strengthen, and has increased the design difficulty of continuously tracked vehicle, structure is complicated, is not suitable for using on middle-size and small-size vehicle.The patent No. is 5,004,060, denomination of invention is the US Patent of " the continuously tracked vehicle diff with epicyclic train ", and the major defect of this steering hardware is to join the tooth difficulty, requires gear that strict drive connection is arranged.
The patent No. is 91220811.2, name is called the Chinese utility model patent of " continuously tracked vehicle power steering mechanism ", the major defect of this bogie of car is: the sun wheel of its power input bevel gear wheel and the right and left is fixed on the same axis, after the planetary transmission gear ring that turns to finishing bevel gear cuter and limit, place on both sides is fixed together, also be bearing on this root axle, and the two ends, the left and right sides of this root axle are bearing in the axis part of left and right output shaft.Power is imported bevel gear wheel, is turned to the engagement force of finishing bevel gear cuter all bigger, and limited, the poor lubrication in axis part space of left and right output shaft is difficult to guarantee lubricated fully and enough intensity.At power input bevel gear wheel, turn under the effect of engagement force of finishing bevel gear cuter, the axle at their places will move or be out of shape unavoidably, at this moment, mobile, generation unbalance loading that the sun wheel at these root axle two ends will produce, and this unbalance loading is very irrational for planetary transmission.Moving or distortion of this root axle also can cause the planetary transmission gear ring on both sides to move, take place unbalance loading, and this unbalance loading also is very irrational for planetary transmission simultaneously.The input shaft of this patent adopts bevel drive, makes the width of this mechanism bigger, and structure is not compact, because this mechanism turns to input finishing bevel gear cuter diameter bigger, has reduced the transmitting ratio of steerage gear simultaneously, has increased the gear mesh force of steerage gear.
Summary of the invention
Technical matters to be solved by this invention is to overcome the shortcoming of the steer-drive of above-mentioned continuously tracked vehicle, provide a kind of reasonable in design, simple in structure, turn to flexibly, the steer-drive of continuously tracked vehicle that stability and commonality are good.
The technical scheme that solves the problems of the technologies described above employing is: be provided with the power input shaft that connects with miniature gears below box house, be provided with bearing between power input shaft and the casing, the big gear wheel that is installed on the tween drive shaft is meshed with miniature gears, tween drive shaft is provided with left sun wheel and right sun wheel, at least 2 left lateral star gears that connect with left output shaft are meshed with left sun wheel, the left gear ring that connects with left angular wheel is meshed with left lateral star gear, at least 2 right lateral star gears that connect with right output shaft are meshed with right sun wheel, the right gear ring that connects with right finishing bevel gear cuter is meshed with right lateral star gear, be provided with bearing between the left end of tween drive shaft and the left gear ring, be provided with bearing between right-hand member and the right gear ring, casing be provided with the end with turn to that finishing bevel gear cuter combines as a whole turn to the control input shaft, all be meshed with the left angular wheel of left gear ring connection with the right finishing bevel gear cuter of right gear ring connection, turn between control input shaft and the casing and be provided with bearing with turning to finishing bevel gear cuter.Above-mentioned miniature gears and big gear wheel are cylindrical wheel; Tween drive shaft is a hollow shaft; The right-hand member of left side output shaft is provided with the left steady arm with left sun wheel overlap joint, the left end of right output shaft is provided with the besthomer with right sun wheel overlap joint, be provided with bearing between left axle sleeve that connects with left gear ring and the casing, be provided with bearing between right axle sleeve that connects with right gear ring and the casing, be provided with bearing between left side output shaft and the left axle sleeve, be provided with bearing between right output shaft and the right axle sleeve.
