Abstract
A transfer case power takeoff device for a special purpose vehicle mainly solves the problem that the prior special purpose car has high technical difficulty and modification cost when taking off the power from a gearbox. The power take off device is characterized in that a transfer case (1) is connected with the connecting disc (3) of a power takeoff (2) through bolts, and the splined sleeve(4) of the guiding shaft of the power takeoff (2) is meshed with the neutral gear driving spline shaft (5) of the transfer case (1). The transfer case power takeoff device for a special purpose vehicle has the characteristics of low technical difficulty and modification cost.
Description
Technical field:
The utility model relates to the used power takeoff of oil field special purpose vehicle, especially special purpose vehicle auxiliary gear box power takeoff.
Background technology:
In the field, oil field,, must reequip existing car in order to satisfy operation needs such as drilling well, test, oil recovery.And the takeoff output of existing car is reequiped, be the emphasis of repacking.The large-scale truck trailer chassis of domestic production at present is at need during from the chassis power taking, all be can only adopt traditional from the change speed gear box power taking, yet it is also inconvenient under many situations from the change speed gear box power taking, for example the long build-up of pressure of hydraulic power line is not enough, perhaps the power taking insufficient space fails to lay down hydraulic actuating cylinder etc., technical risk when therefore having increased the repacking vehicle and repacking cost.
The utility model content:
In order to solve existing special purpose vehicle from change speed gear box power taking technical risk and the high problem of repacking cost, the utility model provides a kind of special purpose vehicle auxiliary gear box power takeoff, this special purpose vehicle auxiliary gear box power takeoff possess skills difficulty and the low characteristics of repacking cost.
The technical solution of the utility model is: this special purpose vehicle auxiliary gear box power takeoff comprises auxiliary gear box, and auxiliary gear box links to each other with the terminal pad of power takeoff by bolt, and the spline housing of the power takeoff axis of guide is meshed with auxiliary gear box neutral drive splines axle.
The utlity model has following beneficial effect: this special purpose vehicle auxiliary gear box power takeoff is owing to take such scheme, has following effect, shorten hydraulic power line and cross length, guaranteed hydraulic pressure, increased the power taking space, take very little space at the auxiliary gear box rear portion, auxiliary gear box power takeoff volume-diminished, solved from change speed gear box power taking and inconvenient, technical risk when therefore having reduced the repacking vehicle and repacking cost, can make technical personnel when the power taking system of design repacking vehicle, select face wider, thereby make the contour structures of vehicle more attractive in appearance, overall performance is more reliable, can allow some leeway for the dress part that goes up of remoulded car, and power taking unit (as hydraulic actuating cylinder) reduced loss in efficiency when the postmedian of chassis.When transforming the unit list pump cementing concrete truck of cementing concrete truck, adopt the north benz chassis of this scheme, respond well by its power taking of evidence, hydraulic work system is normal.Possess skills difficulty and repacking cost low characteristics of this special purpose vehicle auxiliary gear box power takeoff thus.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
1-auxiliary gear box among the figure, 2-power takeoff, 3-terminal pad, 4-spline housing, 5-neutral drive splines axle.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, this special purpose vehicle auxiliary gear box power takeoff comprises auxiliary gear box 1, and auxiliary gear box 1 links to each other with the terminal pad 3 of power takeoff 2 by bolt, and the spline housing 4 of power takeoff 2 axis of guides is meshed with auxiliary gear box 1 neutral drive splines axle 5.
This power takeoff mainly is made up of spline, terminal pad, induction opening, signal switch interface, output shaft and butt flange six parts.Principle of work: at first change speed gear box is suspended to neutral (engine in situ starts); Secondly auxiliary gear box 1 also is suspended to neutral, at this moment, chassis is not walked, but can be from the outside transfer torque of neutral gear; Opening power takeoff 2 master cocies then is suspended to power takeoff 2 on the auxiliary gear box, power takeoff 2 with the air inlet power taking is an example, open power takeoff 2 back air pressure and enter, and promote spline housing 4 and on the neutral drive splines axle 5 of auxiliary gear box 1, be connected with a joggle, carry out power taking along guide bushs; Regulate the change speed gear box gear at last and can carry out power taking control.At this moment, power takeoff 2 connects from auxiliary gear box 1 power taking by spline housing 4, and passes to outside power taking unit (as hydraulic actuating cylinder) by butt flange.This special purpose vehicle auxiliary gear box power takeoff is owing to take such scheme, directly link to each other with auxiliary gear box 1 by power takeoff 2, has following effect, shorten hydraulic power line and cross length, guaranteed hydraulic pressure, increased the power taking space, take very little space at auxiliary gear box 1 rear portion, auxiliary gear box 1 power takeoff 2 volume-diminished, solved from change speed gear box power taking and inconvenient, technical risk when therefore having reduced the repacking vehicle and repacking cost, can make technical personnel when the power taking system of design repacking vehicle, select face wider, thereby make the contour structures of vehicle more attractive in appearance, overall performance is more reliable, can allow some leeway for the dress part that goes up of remoulded car, and power taking unit (as hydraulic actuating cylinder) reduced loss in efficiency when the postmedian of chassis.When transforming the unit list pump cementing concrete truck of cementing concrete truck, adopt the north benz chassis of this scheme, respond well by its power taking of evidence, hydraulic work system is normal.Possess skills difficulty and repacking cost low characteristics of this special purpose vehicle auxiliary gear box power takeoff thus.
