Abstract
The utility model relates to a transmission device of an articulated vehicle. The transmission device comprises a shell, an input shaft, an intermediate shaft, a rear output shaft, a front output shaft and a lubricant pump arranged inside the shell; the rear output shaft is meshed with a planet carrier, a planet wheel, a differential case, a front half-axle gear, a rear half-axle gear, a driven wheel, a second sliding gear sleeve and a sun gear set to form a differential device; a first sliding gear sleeve is meshed with a down-shift gear and an up-shift gear to form a gear shifting mechanism. The utility model has simple structure and is easy to manufacture and convenient to operate; the high-speed or low-speed running of the transmission box is controlled by meshing the first sliding gear sleeve, the down-shift gear and the up-shift gear through operating a shifting system; the speed changing range of the whole vehicle is enlarged; different shafts are designed for the front and rear outputs, the distance between a front bridge and a rear bridge is shortened, and the vehicle-mounting capability and the dynamic performance are strengthened; in addition, the component twists of the front output and the rear output are realized by controlling the meshing between the second sliding gear sleeve and the driven wheel according to the road conditions, and the durability and the reliability are improved.
Description
Technical field
The utility model relates to a kind of gear drive, is specifically related to a kind of 4 * 4 articulator transmission devices that are used for.
Background technique
Along with engineering machinery science and technology is constantly progressive, increasingly high for the onboard capabilities and the power performance requirement of heavy machinery, have turn performance and road conditions adaptive capacity preferably in order to make vehicle, the chassis structure of hinge has obtained extensive use.Present chassis structure is: motor-transmission case-articulated mounting.This transmission case collection clutch, speed changer, transmission device be one, though shortened the rigidity that propeller shaft length increases the chassis, also there is certain shortcoming in it: the driving gear that relates to is more, makes the transmission case complex structure, and bearing capacity is limited; Slewing range is limited, and front and back are output as rigid joint can not be divided and turn round, and maintenance cost is high; Front and back output is coaxial, and the bridge spacing increases before and after making, to the certain influence of car load power performance generation.
Summary of the invention
The purpose of the utility model is the shortcoming that will overcome above-mentioned technology, and a kind of slewing range that both can increase vehicle is provided, and can front and back output be divided again and turn round compact structure, long service life, the articulator transmission device that maintenance cost is low.
The articulator transmission device of the utility model comprises housing and the input shaft, jack shaft, rear output shaft, front output shaft and the lubricating pump that are arranged in the housing, it is characterized in that: differential mechanism is formed in rear output shaft and planet carrier, planet wheel, differential carrier, half front axle gear, back differential gear, follower, second sliding gear collar and sun gear engagement; First sliding gear collar is formed gear with low retaining gear, high retaining gear engagement.
Described front output shaft is connected with propons, and rear output shaft is connected with back axle.
The articulator transmission structures of the utility model is simple, easy to manufacture, easy to operate, makes first sliding gear collar and height keep off gear engagement through the operation shifting system and controls transmission case high speed or low-speed running, increase the slewing range of car load; The disalignment design is adopted in front and back output, and the spacing of bridges has strengthened onboard capabilities and power performance before and after having shortened; Can realize that through the engagement of controlling second sliding gear collar and follower the branch of front and back output is turned round according to road conditions in addition, improve its serviceability and reliability.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure 1, input shaft, 2, low retaining gear, 3, first sliding gear collar, 4, high retaining gear, 5, lubricating pump, 6, jack shaft; 7, odometer, 8, sun gear, 9, rear output shaft, 10, back axle, 11, front output shaft; 12, propons, 13, planet carrier, 14, planet wheel, 15, differential carrier, 16, the half front axle gear; 17, back differential gear, 18, follower, 19, second sliding gear collar, 20, housing, 21, gearbox.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further to describe:
The articulator transmission device of the utility model is by housing 20 and the input shaft 1, jack shaft 6, rear output shaft 9, front output shaft 11 and the lubricating pump 5 that are arranged in the housing 20; Rear output shaft 9 is formed a differential mechanism with planet carrier 13, planet wheel 14, differential carrier 15, half front axle gear 16, back differential gear 17, follower 18, second sliding gear collar 19 and sun gear 8 engagements; First sliding gear collar 3 is formed a simple and easy gear with low retaining gear 2, high retaining gear 4 engagements.Front output shaft is connected with propons, and rear output shaft is connected with back axle.
The articulator transmission device of the utility model is work like this:
During low speed, through the operation shifting system, make first sliding gear collar 3 and low retaining gear 2 engagements, low retaining gear 2 drives jack shaft 6 successively, follower 18 rotates, and through differential mechanism transmission of power is exported to front and back; In like manner, first sliding gear collar 3 and high retaining gear 4 engagements during high speed.
When wheel-slip appears in vehicle,, make second sliding gear collar 19 and follower 18 engagements through the operation shifting system; Power is passed to planet wheel 14 from jack shaft 6 through follower 18, differential carrier 15, planet carrier 13; Simultaneously follower 18 drives sun gears 8 through second sliding gear collar 19 and rotates, the planet wheel 14 not rotation of revolving round the sun this moment, and whole differential mechanism is differential not; Output has strengthened the rigidity on chassis with turning round before and after making; Under the usual condition; Second sliding gear collar 19 separates with follower 18; Power is passed to planet wheel 14 from jack shaft 6 through follower 18, differential carrier 15, planet carrier 13, but planet wheel 14 revolution rotations at this moment drive whole differential mechanism running; Front and back output divides to be turned round, and has improved the road adaptive capacity of car load.
