Abstract
This utility model relates to a single shaft power take-off, which is cooperatively used with DC9J150T or DC9J150TA automobile gearbox. A power take-off shaft is arranged on the shell body of the power take-off through the bearing, an input gear is barely sleeved on the shaft, the combination or separation of the power of the power take-off shaft is through this manner: The input gear is fabricated with outer spline, the power take-off shaft is also fabricated with the same outer spline as on the input gear, a sliding sleeve with spline holes cooperating with the outer spline is arranged on the power take-off shaft or the input gear, a shifting fork groove is fabricated on the sliding sleeve, a shifting fork card is arranged in the shifting fork groove, the sliding sleeve is driven to move in axial direction along the outer spline when the shifting fork is moved, the input gear transfers power to the sliding sleeve when the sliding sleeve meshes with both the outer spline of the input gear and the outer spline of the power take-off shaft, and further the power take-off shaft is driven to rotate by the drive of the sliding sleeve to realize power output. The input gear idle rotates on the power take-off shaft when the shifting fork makes the sliding sleeve mesh with one of the outer splines, thus no power is output.
Description
Technical field
The utility model relates to a kind of mechanical device that obtains power and output from automobile gearbox, is more particularly to a kind ofly to export matching used a kind of single shaft power take-off with DC9J150T or DC9J150TA type automobile gearbox.
Background technique
Power take-off be by the gear in the vehicle gear box or pto provide power and outwards output a kind of obtain mechanical device with transferring power.The vehicle operation machine obtains power by power take-off, and being used for other operation becomes special type or special-purpose vehicle, as fire-fighting truck, sprinkling truck, road sweeper, bulk cement truck etc.Form by the input shaft and the output shaft of same axis with DC9J150T or the matching used power take-off of DC9J150TA type automobile gearbox at present, be equipped with on the input shaft input gear and gear engagement on the automobile gearbox obtain power and by sliding sleeve move and output shaft in conjunction with or separate the combination that reaches power and output shaft or separate.And dock by needle bearing between input shaft and the output shaft, because the needle bearing bearing capacity is little, output shaft is again an overhang, and is comparatively abominable in the operating mode at needle bearing place.Therefore, the needle bearing premature damage often taking place easily in actual use, seriously influences the quality and the working life of power take-off.
Summary of the invention
The purpose of this utility model provides a kind of good reliability, simple in structure, good manufacturability, a kind of single shaft power take-off that bearing capacity is strong.
In order to overcome the technological scheme that above-mentioned defective adopts be: comprise the power take-off housing, the input gear, declutch shift shaft, shift fork is housed on the declutch shift shaft, it is characterized in that by bearing auxiliary drive shaft being housed on the power take-off housing, input gear sky is enclosed within on the auxiliary drive shaft, the combination of auxiliary drive shaft power or separation be by: input is shaped on external splines on the gear, also be shaped on the auxiliary drive shaft with import gear on identical external splines, on the auxiliary drive shaft or input the sliding sleeve of the wounded in the battle keyhole that matches with external splines is housed on the gear, be shaped on fork slot on the sliding sleeve, shift fork is stuck in the fork slot, when mobile shift fork, drive to slide on the external splines and move axially, when sliding sleeve during not only with the external splines engagement of input gear but also with the external splines engagement of auxiliary drive shaft, the input gear is passed to sliding sleeve with power, drives the auxiliary drive shaft rotation by sliding sleeve again, realizes power output; When shift fork made sliding sleeve only with one of them external splines engagement, the input gear dallied on auxiliary drive shaft, and auxiliary drive shaft is motionless, unpowered output.
A kind of single shaft power take-off according to the such scheme manufacturing changes original two axles into an auxiliary drive shaft, has cancelled needle bearing.The integrity enhancing of power take-off can greatly be improved working life.
Description of drawings
Figure is a kind of plan view of single shaft power take-off.
Wherein: 1, input gear; 2, sliding bearing; 3, auxiliary drive shaft; 4,32306 bearings; 5,32207 bearings; 6, power take-off housing; 7, external splines; 8, sliding sleeve; 9, fork slot; 10, shift fork; 11, declutch shift shaft; 12, end cap; 13, screw; 14, compression retracteding position spring; 15, flat key; 16, power connects dish.
Embodiment
The utility model will be further described below in conjunction with the drawings and specific embodiments.
As seen from the figure, input gear 1 is enclosed within on the auxiliary drive shaft 3 by sliding bearing 2 skies, and auxiliary drive shaft 3 is respectively 32306 bearings 4 by two and 32207 bearings 5 are installed on the power take-off housing 6.On auxiliary drive shaft 3, be shaped on external splines 7, input also be shaped on the gear 1 with auxiliary drive shaft 3 on identical external splines, the sliding sleeve 8 of associated wounded in the battle keyhole is housed on the external splines 7 of auxiliary drive shaft 3, be shaped on fork slot 9 on the sliding sleeve 8, shift fork 10 is stuck in the fork slot 9, and shift fork 10 is installed in shift fork 10 in the power take-off housing 6 by declutch shift shaft 11.End face at declutch shift shaft 11 is equipped with end cap 12, on end cap 12, be shaped on screw 13, on can be connected with the pipeline of pressurized air or hydraulic oil, be used for promoting declutch shift shaft 11 and drive shift fork 10, at it compression retracteding position spring 14 is housed oppositely, make shift fork 10 be pressed in shown position by compression retracteding position spring 14 under the situation of non-compressed air or hydraulic oil input, auxiliary drive shaft 3 is not combined into unpowered output state with input gear 1.When passing through screw 13 when the end face of declutch shift shaft 11 is imported pressurized air or hydraulic oil, driving sliding sleeve 8 during mobile shift fork 10 moves axially on auxiliary drive shaft 3, when sliding sleeve 8 during not only with the external splines engagement of input gear 1 but also with the external splines engagement of auxiliary drive shaft 3, input gear 1 is passed to sliding sleeve 8 with power, drive auxiliary drive shaft 3 rotations by sliding sleeve 8 again, realize power output.Also sliding sleeve 8 can be arranged in according to above-mentioned principle on the external splines of input gear 1, by the external splines engagement of sliding sleeve 8 to auxiliary drive shaft 3, realize the combination of power, just with the end cap among the figure 12, declutch shift shaft 11 and shift fork 10, the assembling of compression retracteding position spring 14 turnbacks, the axial dimension of corresponding part adjusts and gets final product.For making power output and being connected, on auxiliary drive shaft 3, be connected with power and connect dish 16 by flat key 15, working machine can connect with power and coil 16 and be connected and obtain power.
