Abstract
The utility model discloses a flexible wheel base bridge, including the pontic, axle housing and outer axle housing in the pontic is equipped with, the displacement motor has set firmly on the outer axle housing, the displacement motor links to each other with the the initiative taper gear transmission, the initiative taper gear's both ends link to each other two with two driven bevel gear transmissions respectively driven bevel gear links to each other with lead screw drive respectively, two the lead screw links to each other with the screw transmission, the screw is fixed on the interior axle housing, the utility model has the advantages of: realized that the car gage is electrodeless adjustable, be applicable to the inconsistent circumstances of different ground interblock ridge distance, greatly expanded the application scope of vehicle, had important practical value.
Description
Technical field
This utility model relates to a kind of agricultural machinery, specifically a kind of changeable wheel track bridge, belongs to agricultural mechanical field.
Background technology
Traditional agricultural machinery is in cultivating procedure, and owing between different plot, row spacing is inconsistent, and car gage is non-adjustable,
The agricultural machinery causing same model cannot be suitable for the operation in different plot, so that the scope of application of equipment greatly receives
Limit.
Summary of the invention
In order to solve the problems referred to above, this utility model devises a kind of changeable wheel track bridge, it is achieved that car gage is electrodeless can
Adjust, it is adaptable to the situation that between different plot, row spacing is inconsistent, be greatly expanded the scope of application of vehicle, there is important practicality
It is worth.
The technical solution of the utility model is:
Changeable wheel track bridge, including pontic, described pontic is provided with interior axle housing and outer axle housing, and described outer axle housing is installed with displacement
Motor, described displacement motor is connected with drive bevel gear transmission, and described drive bevel gear is meshed with two driven wheels of differential, and two
Individual described driven wheel of differential is connected with lead screw transmission respectively, and two described leading screws are connected with screw transmission respectively, two described silks
Mother is each attached on described interior axle housing.Displacement motor connects taper travelling gear, and taper travelling gear connects two leading screw tapers
Gear, drives it to rotate, so that leading screw rotates, makes screw move axially, and screw is fixing with interior axle housing to be connected, in final drive
Axle housing moves relative to outer axle housing, it is achieved displacement, is rotated forward by switching displacement motor and reverses, it is achieved be flexible.
Further, described displacement motor is connected with described drive bevel gear transmission by adapter sleeve.
Further, described leading screw is structure as a whole with described driven wheel of differential.
Further, the rotation direction of two described driven wheels of differential is contrary, so that two displacement directions are that symmetry is entered
Go out.
Further, described pontic is connected with wheel drive by running motor, and described running motor is provided with hub reduction
Mechanism.
This utility model vehicle bridge is applicable to propons, back axle, propons and back axle and uses simultaneously, displacement simultaneously, is suitable for different
Row spacing, and make vehicle have the function of four-wheel drive, power is bigger, has the function of four-wheel steering, and the radius of turning is less.
During displacement, fluid motor-driven pitch-changing mechanism rotating, pitch-changing mechanism is by axle housing in screw mechanism promotion both sides
Stretch out to both sides, it is achieved displacement.Wheelspan adjusting range 1800-2300mm.
The utility model has the advantage of: achieve car gage electrodeless adjustable, it is adaptable between different plot, row spacing differs
Situation about causing, is greatly expanded the scope of application of vehicle, has important practical value.
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment；
Fig. 2 is the vertical view of this utility model embodiment；
Fig. 3 is the gear connection structure schematic diagram of this utility model embodiment.
Detailed description of the invention
Hereinafter preferred embodiment of the present utility model is illustrated, it will be appreciated that preferred embodiment described herein
It is merely to illustrate and explains this utility model, being not used to limit this utility model.
Embodiment 1
As shown in Figure 1-2, a kind of changeable wheel track bridge, including pontic, described pontic passes through running motor 1 and wheel drive phase
Even, described running motor 1 is provided with wheel hem retarding mechanism 2, and described pontic is additionally provided with steering cylinder 3, interior axle housing 4 and outer axle housing 5, institute
Stating and be installed with displacement motor 6 on outer axle housing 5, described displacement motor 6 is connected with drive bevel gear 8 transmission by adapter sleeve 10, institute
State the transmission that is meshed respectively of the two ends of drive bevel gear 8 with two driven wheels of differential 7 to be connected, two described driven wheels of differential 7 points
Not being connected with leading screw 9 transmission, two described leading screws 9 are connected with screw 11 transmission respectively, and described screw 11 is fixed on described interior bridge
On shell 5.Displacement motor connects taper travelling gear, and taper travelling gear connects two leading screw angular wheels, drives it to rotate, from
And make leading screw rotate, and make screw move axially, screw is fixing with interior axle housing to be connected, and in final drive, axle housing moves relative to outer axle housing
Dynamic, it is achieved displacement, rotated forward by switching displacement motor and reverse, it is achieved be flexible.
Wherein, described leading screw 9 is structure as a whole with driven wheel of differential 7.
It addition, the rotation direction of two described driven wheels of differential is contrary, so that two displacement directions are symmetrical turnover.
This utility model vehicle bridge is applicable to propons, back axle, propons and back axle and uses simultaneously, displacement simultaneously, is suitable for different
Row spacing, and make vehicle have the function of four-wheel drive, power is bigger, has the function of four-wheel steering, and the radius of turning is less.
