Abstract
The utility model relates to a heavy duty motor vehicle power takeoff, comprising a housing 3, main shaft 14 and an output shaft 9 which is mounted in parallel with the main shaft. Wherein, the main shaft is fixed on the housing, the both ends of the output shaft are respectively supported on the fore and after bearing seating fixed with the housing by a bearing. The heavy duty motor vehicle power takeoff is characterized in that the main shaft is provided with two sizes double gear supporting by a conical roller bearing; the spline of the output shaft is connected with an output gear5, and the output gear5 driving by the shift fork 19 is engaged with the pinion of the double gear. The housing is provided with a cylinder28 ;one end of the piston 26 of the cylinder inside is tipped on the spring 24; the cylinder rod is connected with one end of the shift fork ; one end of shift fork is connected with the output gear. The utility model can be installed under the transmission case when the users uses. The big gear of the double gear 14 is engaged with the normal rotation gear of the transmission case; the shift fork drives the output gear5 to move, and which is engaged with the pinion of the double gear14;meanwhile, the output shaft 9 outputs dynamic, which can improve the performance of the operation, and can increase the condition of the lubrication.
Description
Technical field
The utility model relates to the power takeoff with the heavy duty automobile gear box adapted.
Technical background
In the side or the back of casing, there is poor lubrication with the power taking position of change speed gear boxs in most of heavy goods vehicles of the prior art, can only intermittent use etc. problem.The RT11710B two-pack shaft gearbox that U.S. Eaton produces has compact conformation, durability and improves, can alleviate gearshift power, makes the advantage such as life-span raising of gear and be applied on domestic automobile, but the position of its power taking adopts conventional power takeoff can't reach lubricant effect preferably in the bottom of casing.
Summary of the invention
The purpose of this utility model provides a kind of and RT11710B two-pack shaft gearbox adapted, in change speed gear box bottom power taking, the heavy motor vehicle power takeoff that operating characteristic, lubricating condition are improved.
The technical solution adopted in the utility model is such, it is a kind of heavy motor vehicle power takeoff, comprise housing, main shaft and the output shaft of parallel installation with it, wherein main shaft is fixed on the housing, the output shaft two ends by bearing be supported on respectively with the fixing antero posterior axis bearing of housing on; It is characterized in that: have the big or small dual gear by bearings on the main shaft, the output shaft upper spline connects output gear, this gear under the drive of shift fork can with the pinion of dual gear; Cylinder is installed on the housing, and an end of piston withstands on the spring, and piston rod is connected with an end of shift fork, and the other end of shift fork is connected on the output gear.
The utility model is because the advantage that described structure youngster has is very tangible, that is:
1, because power takeoff is installed in the bottom of change speed gear box, make its lubricating condition obtain good improvement, make the work that power takeoff can be long-term, can only intermittently used history thereby changed power takeoff.
2, power takeoff is handled gearshift flexibly, power-transfer clutch need only be depressed 5～8 seconds, open baroswitch just can shift gears very easily, out of supply.
Description of drawings
Accompanying drawing 1 is a generalized section of the present utility model;
Accompanying drawing 2 is the B-B cutaway view of accompanying drawing 1;
Accompanying drawing 3 is the A-A cutaway view of accompanying drawing 2.
Referring to accompanying drawing, 1-rear bearing block, 2-bearing seat cushion, 3-housing, 4-main shaft, 5-output gear, 6-bearing, 7-collar, 8-oil sealing, 9-output shaft, 10-plug screw, 11-pin, 12-packing ring, 13-tapered roller bearing, 14-dual gear, 15-tapered roller bearing, 16-O RunddichtringO, 17-O RunddichtringO, 18-front-end bearing pedestal, 19-shift fork, 20-spring, 21-cylinder end piece, 22-cylinder head, 23-air switch, 24-spring, 25-O type circle, 26-piston, 27-cylinder-top gasket, 28-cylinder among the figure.
The specific embodiment
Referring to accompanying drawing, the heavy motor vehicle power takeoff in the accompanying drawing is connected with change speed gear box in the bottom, the normal commentaries on classics gear mesh in big gear wheel on the dual gear 14 and the change speed gear box wherein, miniature gears idle running, this moment the power takeoff no-output.When the needs power takeoff is worked, open sky institute switch 23, cylinder intake, piston 26 overcomes the top power of spring 24 and moves, this moment, piston rod drove shift fork 19, by shift fork drive that output gear 5 moves and with dual gear 14 on pinion, this moment is by output shaft 9 outputting powers.When not needing power takeoff work, cut off air switch, spring 24 returns push back original reference position with shift fork automatically, and the miniature gears on output shaft and the dual gear breaks away from this moment, and power takeoff can not outputting power.
In said structure, the dual gear 14 on the main shaft 4 is supported by tapered roller bearing 12,15; The admission port of power takeoff cylinder 28 is arranged on the initiating terminal of the stroke of piston, and exhausr port is arranged on the end of piston stroke.
Claims (3)
1, a kind of heavy motor vehicle power takeoff comprises the output shaft (9) of housing (3), main shaft (4) and parallel installation with it, and wherein main shaft is fixed on the housing, the output shaft two ends by bearing be supported on respectively with the fixing antero posterior axis bearing of housing on; It is characterized in that: have the big or small dual gear (14) that supports by tapered roller bearing on the main shaft, output shaft (9) upper spline connects output gear (5), this gear under the drive of shift fork (19) can with the pinion of dual gear; Cylinder (28) is installed on the housing, and an end of piston (26) withstands on the spring (24), and piston rod is connected with an end of shift fork, and the other end of shift fork is connected on the output gear.
