Abstract
The utility model discloses a coaxial straight push-gear clutch type power takeoff device. The utility model mainly comprises a driving gear, a driven gear provided with an inner spline, an output shaft provided with an outer spline and a piston. The concave position of the output shaft at the back part of the output shaft is provided with a long gain. The inner part of the output shaft is provided with a movable clutch shaft. A pin shaft penetrates through the long gain and the clutch shaft on the output shaft, and the pin shaft is fixedly connected with the driven gear by holes at the upper end and the lower end of the pin shaft. The utility model has the advantages of simple structure, small volume, light weight, low cost, stable, reliable, flexible and smooth coaxial clutch, and less part abrasion.
Description
The utility model belongs to the device that is used with change speed gear box, relates generally to a kind of coaxial gears to engage and disengage formula power takeoff that directly pushes away.
The automobile-used shift fork clutch-type power takeoff of putting into gear mainly contains manually and pneumatic two kinds.Manually shift fork is put into gear, and the clutch-type power takeoff volume is big, heavier, operation is dumb.The air fork clutch-type power takeoff of putting into gear is to promote piston with atmospheric pressure, reaches the purpose of takeoff output thereby remove to stir the ring gear that has female splines by axis of guide shifting fork mechanism, spring etc. with the spur gear engagement of the front end of active dual gear having to slide on the output shaft of male splines forward.Though it is with manually specific volume is little, in light weight mutually, because aerodynamic force acts on the piston, again by the shifting fork mechanism handsetting gear, thereby the monolateral overbalance of application force causes clutch not smooth, is out of order easily, and parts depreciation is big.In addition, air chamber and shifting fork mechanism occupy than large space, so the power takeoff profile is still bigger.
The purpose of this utility model is at above deficiency, and a kind of simple in structure, in light weight, coaxial gears to engage and disengage formula power takeoff that directly pushes away that cost is low is provided.
The purpose of this utility model realizes by the following technical solutions: described power takeoff comprises the duplex driving gear, have the ring gear of female splines, have the output shaft and the piston of male splines, piston is positioned at the rear end of output shaft, female splines on the ring gear is corresponding with the male splines of output shaft, male splines recess at the output shaft rear portion is provided with a long gain, the inside of output shaft is provided with a clutch shaft movably, one bearing pin is arranged, pass long gain and clutch shaft on the output shaft, captive joint with ring gear in the hole at two ends up and down by bearing pin.
The leading section of described clutch shaft is provided with a hole that holds retracing spring, and the spring other end holds out against the oily closure plate on the output shaft.The rear end of clutch shaft holds out against piston.
The rear end that is used to hold out against piston on the described clutch shaft is an awl point.
By last structure as can be seen, the utility model is simple in structure, volume is little, in light weight, thereby cost is also low.Because bearing pin is connected as a single entity clutch shaft and ring gear, makes in clutch shaft and the ring gear long gain on output shaft and slides, realize that coaxial clutch is steadily reliable, smooth flexibly, parts depreciation is little.The power that is added on the clutch shaft rear end by piston can enlarge range of use from manual force, aerodynamic force and the power etc. of surging.
Below in conjunction with embodiment the utility model is further described:
Fig. 1 is an integral structure scheme drawing of the present utility model.
Shown in the figure, described power takeoff comprises duplex driving gear 2, have the ring gear 6 of female splines, have the output shaft 4 and the piston 9 of male splines, and piston 9 is positioned at the rear end of output shaft 4.Female splines on the ring gear 6 is corresponding with the male splines of output shaft 4.Male splines recess at output shaft 4 rear portions is provided with a long gain 8, the inside of output shaft 4 is provided with a clutch shaft 3 movably, there is a bearing pin to pass long gain 8 and clutch shaft 3 on the output shaft, captive joint with ring gear 6 in hole by bearing pin two ends about in the of 5, bearing pin 5 can move in long gain 8 scopes.The leading section of clutch shaft 3 is provided with a hole that holds retracing spring 7, and spring 7 other ends hold out against the oily closure plate on the output shaft, and the rear end of clutch shaft 3 holds out against piston 9.The rear end of clutch shaft 3 is an awl point.
After the base plate 1 of described power takeoff was connected and fixed with right side window on the existing change speed gear box of automobile, the backgear of the active dual gear 2 on the power takeoff promptly was meshed with normal commentaries on classics gear in the change speed gear box.Normal commentaries on classics gear in the engine starting change speed gear box promptly rotates with the active dual gear 2 of power takeoff, and at this moment ring gear 6 remains static on output shaft.When being added on clutch shaft 3 rear ends by piston 9 under the external effect, clutch shaft 3 compression reseting spring 7 that advances, and lean on bearing pin 5 drives to have the male splines of the ring gear 6 suitable output shafts 4 of female splines to advance, the drive spline output shaft 4 that is meshed with the spur gear of driving gear 2 front ends rotates transfer torques, thereby reaches the purpose of its takeoff output.When elimination acts on the power of clutch shaft rear end, retracing spring 7 effects, clutch shaft 3 resets, and ring gear 6 separates with driving gear 2, and takeoff output stops immediately.
