Summary of the invention
In order to solve the orthodox car power takeoff complicacy is installed, equipment occupation space is big, problems such as power transmission weak effect, and the present invention has designed a kind of new automobile power takeoff.
The technical scheme that the present invention addresses the above problem is: a kind of automobile power takeoff; Comprise casing, input gear axle and output gear shaft are parallel to each other, and are installed in the casing; Input gear axle and output gear shaft are the inner spline gear wheel shaft; The input gear axle sleeve has dual gear, and transmission gear wherein is connected with the output gear shaft gear mesh, and the clutch gear outside is with and its ingear internally toothed annulus.Its advantage is: the castellated shaft of automobile independence output shaft and the clamping of input shaft gear female splines; The castellated shaft clamping of equipment such as the female splines of output gear shaft and water pump, oil pump; Need not to drive equipment such as oil pump or water pump, also cancelled auxiliary bracket and annex thereof simultaneously, saved installing space with transmission shaft; It is compacter that equipment is connected, and reduced the loss in efficiency in the transmission course; The input gear axle sleeve has dual gear; Transmission gear wherein is connected with the output gear shaft gear mesh; The clutch gear outside is with and its ingear internally toothed annulus; Operating personal can through the slip of control internally toothed annulus on clutch gear accomplish its with the engagement of input gear shaft gear with separate, play the effect of clutch.
Described power takeoff, the internally toothed annulus excircle has circumferential recess, clamping shift fork in the groove.Its advantage is: shift fork is connected in the groove, and the control shift fork can make internally toothed annulus move.
Described power takeoff, box house is equipped with air pump, and the air pump piston axle is captiveed joint with shift fork.Its advantage is: operating personal makes the air pump piston axle drive shift fork through the control air pump switch, controls power takeoff, saves time, and has improved work efficiency.
Described power takeoff is equipped with needle bearing between input gear axle and the dual gear.Its advantage is: needle bearing compact conformation volume is little, and running accuracy is high, can both play supporting role to dual gear bearing very high radial load, guarantees that also the running of input gear axle and dual gear can not interact.
Described power takeoff, input gear axle and output gear shaft two ends are equipped with the circular cone roller bearing.Its advantage is: tapered roller bearing can bear big radial weight and axial load; Reduce stress concentration; Prevent part distortion, both gear wheel shaft was played a supporting role, reduced the wearing and tearing that the stress that produces in the power takeoff transmission process causes device proper again.
Described power takeoff, the casing middle part has the hole, and the oil level form is installed on the hole.Its advantage is: because power takeoff is communicated with change speed gear box, power takeoff is identical with the lubricant level of change speed gear box, and the oil level form both can have been monitored the level height of power takeoff, also can reflect the level height of change speed gear box simultaneously.
Described power takeoff, casing output gear axle head has screw hole.Its advantage is: the screw hole of casing is corresponding with the screw hole of oil pump or water pump flange, connects through screw retention, improves the degree that is connected firmly between the two.
Described power takeoff is equipped with the position electric switch that detects internally toothed annulus on the casing.Its advantage is: display equipments such as electric switch and relay indicating light are connected, and when internally toothed annulus and the engagement of input gear axle, the closing of circuit of electric switch is communicated with, and indicator lamp brightens, and operating personal can be known the service condition of understanding power takeoff.
