The utility model discloses a high-gap chain wheel speed-down valve supporting driving axle and a vehicle; and the driving axle comprises a main driving axle; gantry mountings are respectively connected at the both ends of the driving axle, and a speed-reducing device is arranged in the gantry mountings; the speed-reducing device includes a driving wheel, a driven wheel, and the driving wheel is connected with a semi axis of a main driving axle, the driven wheel is connected with a driving wheel by a wheel edge reducer, and the driving wheel is transmitted with the driven wheel by a chain. The longitudinal size of the middle part shell in the main driving axle can be reduced so as to lead the main driving axle to be lifted above the center of the driving wheel and raise the clearance between the driving axle body and the ground, and improve the capacity of getting across complex landforms of the vehicles; thus being applied to various forest vehicles, agricultural wheel-type tractors, loading vehicles for projects and off-road automobiles.
Description
Technical field
The utility model relates to a kind of drive axle of driving vehicle, relates in particular to crack, a kind of highland sprocket wheel deceleration door frame support type drive axle and driving vehicle.
Background technology
Drive axle is mainly used on the takeoff output wheel shaft of various self-propelled vehiclees, drives the wheel revolutions powered vehicle with power and travels; 1～2 wheel respectively is equipped with at the two ends that generally are an axle.For example: agricultural wheeled tractor and engineering are respectively adorned 1 wheel with the drive axle two ends of loader, and transport truck and passenger vehicle drive axle two ends Chang Binglie are equipped with 2 wheels.Its essential structure comprises: main reduction gear, diff, semiaxis and axle housing.The moment of torsion of wheel is by axle housing in-to-in main reduction gear, diff and semiaxis transmission; And car load is born by axle housing.
There is following shortcoming at least in above-mentioned prior art:
Existing drive axle, it takes turns a pontic to ground-surface gap deficiency, and vehicle is relatively poor by open-air complex-terrain ability.
The utility model content
The purpose of this utility model provides a kind of drive axle pontic highland crack sprocket wheel deceleration door frame support type drive axle and the driving vehicle big to ground-surface gap.
The purpose of this utility model is achieved through the following technical solutions:
Crack, highland of the present utility model sprocket wheel deceleration door frame support type drive axle comprises main drive axle, and the two ends of described main drive axle are connected with door frame respectively, and the upper end of described door frame is connected with main drive axle, and the lower end of described door frame is connected with drive wheel.
Driving vehicle of the present utility model, this driving vehicle are provided with above-mentioned crack, highland sprocket wheel deceleration door frame support type drive axle.
The technical scheme that provides by above-mentioned the utility model as can be seen, crack, highland described in the utility model sprocket wheel deceleration door frame support type drive axle and driving vehicle because the two ends of main drive axle are connected with door frame respectively, and are connected with drive wheel by door frame.Pontic is big to ground-surface gap between the wheel of main drive axle, and vehicle is better by open-air complex-terrain ability.
Description of drawings
Fig. 1 is the transmission principle figure of crack, the utility model highland sprocket wheel deceleration door frame support type drive axle.
The specific embodiment
Crack, highland of the present utility model sprocket wheel deceleration door frame support type drive axle, its preferable specific embodiment comprises main drive axle as shown in Figure 1, and the two ends of main drive axle are connected with door frame respectively, the upper end of door frame is connected with main drive axle, and the lower end of door frame is connected with drive wheel.
Main drive axle comprises main driving axle housing 4, is provided with main gear down device in the main driving axle housing 4, and main gear down device comprises bevel pinion 1, bevel gear wheel 2, diff 3 etc., and propulsive effort reaches semiaxis 9 by main drive.
Door frame comprises door frame shell 5, is provided with speed reduction gearing in the door frame shell 5, and speed reduction gearing comprises driving wheel 6, flower wheel 7, and driving wheel 6 is connected with the semiaxis 9 of main drive axle, and flower wheel 7 is connected with the drive wheel (not shown).Can be connected with driving chain 10 between driving wheel 6 and the flower wheel 7, by chain gear.Also can adopt gear transmission or other type of drive as required.
The lower end of door frame can directly be connected with drive wheel, and the power of flower wheel 7 is directly passed to drive wheel; Also can be connected with drive wheel by wheel reduction gear 8, the power of flower wheel 7 passes to drive wheel by wheel reduction gear 8.
Wheel reduction gear 8 can also can be other retarder for gear reducer, planet wheel decelerator or cycloid pin retarder etc.
Main driving axle housing 4 is captiveed joint with door frame shell 5, is used to bear car load.
Driving vehicle of the present utility model is provided with above-mentioned crack, highland sprocket wheel deceleration door frame support type drive axle.This driving vehicle can for forest vehicle, agricultural wheeled tractor, engineering with loader or cross country car etc., also can be other vehicle.
The utility model is on the basis of common drive axle, and the two ends of main drive axle are connected with door frame respectively, and is connected with drive wheel by door frame.Because the effect of support door frame rises on the drive wheels center main drive axle, thereby improved greatly the ground Clearance that drives the pontic bottom, vehicle is better by open-air complex-terrain ability.
Door frame increases the one-level sprocket wheel and slows down, and reduces the reduction ratio of central main gear down device, dwindles the radial dimension of main drive axle central enclosure; The housing of door frame also adopts vertical direction to arrange, improves the space that drives between pontic and the ground; This speed reduction gearing adopts chain sprocket drive, can strengthen two centre of sprocket distances according to the vehicle needs, when realizes bigger door frame height under the situation of chain sprocket structure not changing transmission, reaches the effect that improves the crack, ground by a relatively large margin.
Transmission principle of the present utility model is: drive bevel gear wheel 2 by bevel pinion 1, give semiaxis 9 through diff 3 with power distribution, and drive door frame driving wheel 6, and drive door frame flower wheel 7 through driving chain 10, finally output to drive wheel (not drawing among the figure) by wheel reduction gear 8.
The utility model adopts 3 grades of decelerations: the first order is made up of little, bevel gear wheel in the main drive axle; The second stage is made up of drive sprocket in the door frame and driven sprocket; The third stage is made up of wheel reduction gear; The characteristics that it has high reduction ratio are more suitable for open-air traveling on mountainous region.Dress sprocket wheel deceleration transmission makes by the crack, ground and improves greatly in portal framed structure and the door frame, and has the advantages that hold-down arm length is not subjected to the transmitting ratio restriction.
The above; it only is the preferable specific embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.
