Abstract
The utility model discloses an automobile power takeoff accepting the power of a transmission shaft of a gearbox of an automobile. The utility model is provided with a main shaft of which the middle part is thick and both ends are thin, wherein the middle part of the main shaft is provided with a shifting fork wheel; tooth grooves are arranged inside and outside the shifting fork wheel; a shifting fork groove matched with a shifting fork is arranged on the shifting fork wheel. A front and a back transmission wheels are arranged on the front and the back shaft shoulders of the main shaft through bearings; the corresponding inner sides of the two transmission wheels are provided with tooth grooves matched with the shifting fork wheel; the two transmission wheels are arranged on a shell body through bearings. The front end of the main shaft accepts the power of a front transmission shaft of the gearbox of an automobile; the front transmission wheel transmits the power to other mechanisms; the back transmission wheel is connected with a back transmission shaft of an automobile. The utility model is arranged between the gearbox and a differential gear of an automobile for coupling the front and the back transmission shafts. When the shifting fork wheel is engaged with the transmission wheels, the speed can be regulated only through the shifting of the gearbox, and the speed can be increased without raising the throttle; thereby, the abrasion of a motor is reduced. The utility model has the advantages of energy saving and flexible speed regulation.
Description
Technical field
The utility model relates to a kind of power takeoff, relates in particular to a kind of automobile power takeoff that obtains power from the automobile gearbox transmission shaft.
Background technology
Many vehicles that have specific function concurrently, as crane, bulk cement car, fire extinguishing tanker etc., great majority are equipped with special power takeoff, by the side gear acquisition power of automobile gearbox.Use existing power takeoff, required speed during the spcific power equipment work can only realize by engine governed speed.If will obtain fair speed, then open the throttle wide, make the driving engine speed-raising, meanwhile, the power of driving engine also improves greatly, and for not needing too high-performance spcific power equipment, driving engine has but been done a large amount of idle works, consume too much fuel, caused wearing and tearing and waste.
Summary of the invention
The purpose of this utility model is to provide a kind of transmission shaft from automobile gearbox to obtain power, can obtain the automobile power takeoff of speed change, energy efficient by shifting gears.
The technical solution of the utility model is achieved in that the thin main shaft in thick two, a centre, is provided with the forked plectrum wheel of teeth groove inside and outside the middle part of main shaft is equipped with, and forked plectrum wheel is provided with the fork slot that cooperates with shift fork.By power wheel before and after two of the bearing installations, two power wheel opposed inside have teeth groove to match with forked plectrum wheel at shaft shoulder place, the front and back of main shaft, two power wheels by bearing installation on housing.The front end of main shaft is by the power of the front propeller shaft of flange reception automobile gearbox, and preceding power wheel is to other mechanical transfer power, and back power wheel connects the rear propeller shaft of automobile.
The utility model is installed between automobile gearbox and the diff transmission shaft before and after connecting.When forked plectrum wheel is meshed with power wheel, only need with regard to scalable power wheel transmitting speed by gearbox shifting, thereby export the required power of other power plant, when forked plectrum wheel is meshed with power wheel, only need with regard to adjustable speed by gearbox shifting, also need not open the throttle wide during speed-raising, thereby reduced the wearing and tearing of driving engine.Reach energy-saving and cost-reducing effect, had excellent popularization to be worth.
Description of drawings
Fig. 1, Fig. 2 are the structural representation of two embodiment of the utility model.
Among the figure 1, main shaft, 2, flange, 3, power wheel, 4, housing, 5, shift fork, 6, forked plectrum wheel, 7, power wheel, 8, flange, 9, snap ring, 10, bearing, 11, fork slot, 12, bearing, 13, connect platform, 14,15, forked plectrum wheel, 16,17, shift fork.
The specific embodiment
Introduce the utility model below in conjunction with drawings and Examples.
With reference to Fig. 1.A housing 4 that is installed in the automobile bottom is arranged, the thin main shaft 1 in thick two, a centre is arranged in the housing, main shaft 1 is provided with the middle part of teeth groove, and the forked plectrum wheel 6 of an inside and outside spline is installed, and the excircle of forked plectrum wheel is provided with the fork slot 11 that cooperates with shift fork 5.Shaft shoulder place in both sides, main shaft 1 middle part, power wheel 3 and back power wheel 7, two power wheels 3,7 opposed inside also are provided with teeth groove before being separately installed with by bearing 12,10, match with forked plectrum wheel 6.The front end of main shaft also is provided with teeth groove, matches with the axis hole of flange 2.Flange 2 receives the power of the front propeller shaft of automobile gearbox.Envelope has oil sealing between flange 2 and the preceding power wheel 3.
Two power wheels 3,7 by bearing installation on housing 4.Also can be provided with connection platform 13 on the wherein preceding power wheel 3, be used to install Transmissions such as belt pulley or sprocket wheel, to other power plant transmission power.The rear end of back power wheel 7 is a flange, can directly be connected with the rear propeller shaft flange of automobile, also can be by flange 8 a back kick moving axis transmission power.The rear end of main shaft 1 has snap ring 9 to fix the bearing of back power wheel 7.
In the power wheel 3, stop this moment before by shift fork 5 forked plectrum wheel 6 being dragged on forward, and automotive engine work then can drive other power plant with car, only needs reach required operation power by the gearshift speed governing of change speed gear box.If equipment quits work, automobile remains to be travelled, as long as with the forked plectrum wheel 6 back power wheel 7 of dragging on backward, get final product.
With reference to Fig. 2.On the excircle of forked plectrum wheel 14,15, two forked plectrum wheels of two inside and outside splines that split is installed on the main shaft 1, be equipped with the fork slot that cooperates respectively with shift fork 16,17.Change the engagement or the disengaged position of the engagement of forked plectrum wheel 14 and preceding power wheel 3 or disengaged position, forked plectrum wheel 15 and back power wheel 7, can realize the two the independent control of automobile, power plant.
The utility model is installed between automobile gearbox and the diff, makes main shaft 1 connect the transmission shaft of front and back.When forked plectrum wheel 6,14 is meshed with preceding power wheel 3, only need by gearbox shifting with regard to scalable before the power wheel transmitting speed, thereby export the required power of other power plant.Need not the power of open the throttle wide, raising driving engine, just can obtain bigger speed, energy-saving and cost-reducing effect is arranged, reduced the wearing and tearing of driving engine again, have excellent popularization to be worth.
