Particularly, connecting sleeve 16 can be for being threaded with Placement between the flexible rod 311, and promptly the external part of flexible rod 311 is provided with external thread part, and connecting sleeve 16 is provided with the internal thread part that matches with external thread part; It is fairly simple to be threaded, and connects reliable.
Certainly the Placement between connecting sleeve 16 and the flexible rod 311 not only is confined to the description among this paper, and both can also be for interference fit connects, and the processing technology of two connected element cooperation places is fairly simple, saves user cost.
In another preferred embodiment, above-mentioned telescopic cylinder 31 can be telescopic oil cylinder, and the telescopic oil cylinder that hydraulic circuit drives does not have the pivoting friction parts; Each component long service life, and simple in structure, operation easily; Can realize automation control, and the hydraulic operation campaign is steady.
The hydraulic oil source that drives oil circuit can be from the power source of the hydraulic control system of engineering machinery, and this scheme need not provide extra oil sources, and is simple in structure, and cost is lower.
It is pointed out that the telescopic oil cylinder in the above-mentioned drive unit also can use flexible part replacements such as telescopic cylinder.
Particularly, the means of fixation of telescopic cylinder 31 can adopt following mode: the cylinder body of telescopic cylinder 31 is provided with flange, and telescopic cylinder 31 is fixed on the casing 17 of gearbox device through flange; This Placement is fairly simple reliable.
Bearing 41 among above-mentioned each embodiment can be thrust-bearing, and thrust-bearing both can have been realized the pushing block of clutch 21 and relatively rotating of flexible rod 311, again can the bigger axial force load of CBR.
Certainly, above-mentioned bearing 41 not only is confined to thrust-bearing, also can be the bearing of other types, and for example limit speed is than higher deep groove ball bearing etc.
In a kind of preferred implementation, clutch 21 inside are provided with the spring along its axial deformation, and clutch is connected through spring with said pushing block, and said spring can be the little dish spring of requisite space, also can be stressed more uniform helical spring; During hydraulic coupling on removing telescopic cylinder, under the effect of spring, can realize the quick separation of clutch friction plate.
Wherein, The clutch 21 that connects the diaxon of coaxial line in above-mentioned each embodiment's the gearbox device can be the wet friction slice clutch; The wet friction slice clutch uses oil cooling but; So working life is long, and such clutch can be in half-clutch state work, the running environment of the complicacy of adaptation harbour rubber tired crane tool for a long time.
Gearbox device with gearbox rubber tired crane at a kind of harbour is an example below; Introduce the present invention in detail in the engineering machinery level road working principle when climbing two kinds of different road conditions of going; The staff is to be understood that in related domain; Two kinds of situations that the road conditions of going of engineering machinery not only are confined to describe among this paper are because of identical this paper of working principle of gearbox device gives unnecessary details no longer one by one.
As shown in Figure 3; The jack shaft of gearbox device comprise first transmission shaft 11 coaxial with input shaft, with second transmission shaft 12 of said input shaft engagement and with second transmission shaft 12 coaxial and with the 3rd transmission shaft 13 of said output shaft engagement; Between the input shaft 14 and first transmission shaft 11 and be arranged between second transmission shaft 12 and the 3rd transmission shaft 13 and be equipped with clutch 21; The model of two clutches 21 is chosen according to each size of transmitting power, can be identical, and also can be different; Correspondingly; The operating mechanism of two said clutches can be located at said first transmission shaft 11 and said second transmission shaft, 12 1 sides respectively, is processed with mounting hole respectively on promptly said first transmission shaft and said second transmission shaft, and flexible rod passes mounting hole and connects corresponding pushing block.
When harbour rubber tired crane level road is walked: flexible rod 311 motions in the telescopic cylinder 31 on driving; Flexible rod 311 will drive bearing and move downward; Thereby promote upper end clutch 21 pushing blocks and compress inner two friction plates; Be linked to be an integral body to second transmission shaft 12 and the 3rd transmission shaft 13; Engineering machinery is in high gear work, and the power on the input shaft passes to output shaft 15 through first gear 51, the 3rd gear 53, the 5th gear 55 and the 6th gear 56, reaches the purpose that tire on the drive wheels advances.
When hoist conversion travelling state, remove the driving force that drives the upper end telescopic cylinder, under the effect of upper end clutch medi-spring, separate second transmission shaft 12 and the 3rd transmission shaft 13.
When harbour rubber tired crane climbing walking: the flexible rod 311 that drives in the lower end telescopic cylinder 31 moves upward; Flexible rod 311 will drive bearing and move upward; Thereby promote lower end clutch 21 pushing blocks and compress inner two friction plates; Be linked to be an integral body to first transmission shaft 11 and the 3rd transmission shaft 13, engineering machinery is in bottom gear work.Power on the input shaft passes to output shaft 15 through second gear 52, the 4th gear 54, the 5th gear 55 and the 6th gear 56, reaches the purpose that tire on the drive wheels advances.
Need to prove; Used herein upper and lower wait the noun of locality all be with among Fig. 3 between each component relative position be reference; For the indirect convenience of explaining; Be convenient to those skilled in that art and understand the present technique scheme, should be appreciated that the employed noun of locality of this paper should not limit the application range of this patent file.
Except that above-mentioned self shifter formula gearbox device; The present invention also provides a kind of wheeled construction machinery; Comprise vehicle frame and be arranged at the self shifter formula gearbox device on the said vehicle frame, this self shifter formula gearbox device is above each described self shifter formula gearbox device.
Owing to comprised above-described self shifter formula gearbox device, its also corresponding technique effect in this wheeled construction machinery with this self shifter formula gearbox device.
A kind of preferred embodiment in, wheeled construction machinery specifically can be the harbour wheel mounted crane, in addition, the technical characteristics of other parts of harbour wheel mounted crane can repeat no more at this referring to existing technology.
