Abstract
The utility model relates to a steering driving axle with independent suspension and single cross axle wheel-side transmission, which is characterized in that a main reducer is connected with a flange yoke; the flange yoke is matched with a weld yoke and a spline shaft yoke; an input shaft yoke is fixed on a wheel-side reducer; the wheel-side reducer is connected with a wheel hub; the line between an upper fulcrum and a lower fulcrum of an independent suspension arm is the main pin central line; the intersection point of the main pin central line and the axis of a half axle is the center of a universal joint; the main pin central line and the universal joint center of the wheel-side reducer are superposed with the center of a steering knuckle when a wheel-side planetary gear train is formed; the spline shaft yoke and the weld yoke can move axially in a telescopic way. The wheel-side reducer adopts a single pair of external cylindrical gears or a planetary gear reducer; the wheel-side input shaft is a single cross axle universal joint with a telescopic joint. The steering driving axle with independent suspension and single cross axle wheel-side transmission has higher torque bearing capability and can well satisfy the lightweight, low oil-consumption and high reliability requirements of military vehicles and off-road vehicles.
Description
Technical field
The utility model relates to the steering drive axle of a kind of independent suspension, single cross axle wheel-side transmission, belongs to auto manufacturing, is applicable to all types of commercial vehicle/comm..vehicles, is primarily aimed at military-designed vehicle and cross-country car.
Background technology
The wheel-hub drive steering drive axle structure of present most independent suspension commercial vehicle/comm..vehicles, mostly adopting main reduction gear to pass through all kinds of universal joint wheels limit input shaft connects with wheel reduction gear, to realize the transmission of moment of torsion, simultaneous wheels limit input shaft is also being born the effect that turns near the universal-joint of wheel reduction gear one side.In independent suspension, wheel-hub drive steering drive axle, use at present and more be: ball cage universal-joint or double cardan universal joint formula wheel-hub drive form.Rzeppa joint wheel-hub drive form is harsh to lubricating condition, the cost height, and poor reliability, volume and weight are relatively large, and nominal torque and ultimate angle are little.Double cardan universal joint formula wheel-hub drive form, its universal-joint volume, weight and turn diameter are big, and the double cardan universal joint axial dimension of band spotting device requires bigger.Along with the expansion and the development in domestic military-designed vehicle and cross-country car market, more than two kinds of forms all can not satisfy military-designed vehicle and cross-country car lightweight well, low oil consumption, the operating needs of high reliability;
In addition, the parts of ball cage universal-joint and double cardan universal joint assembly are various, complex structure, and it is bad to fall heavy index, has increased manufacturing, assembling and maintenance use cost.The double cardan universal joint assembly is big owing to axially reaching radial dimension, causes the wheel limit input shaft spline collapsing length difficult arrangement of independent suspension.
Summary of the invention
The purpose of this utility model is to provide the steering drive axle of a kind of independent suspension, single cross axle wheel-side transmission, it is simple in structure, compact, make things convenient for car load to arrange, can effectively realize the transmission of driving torque, can realize the requirement that turns to of tire bob and car load simultaneously.
The technical solution of the utility model is achieved in that the steering drive axle of a kind of independent suspension, single cross axle wheel-side transmission, is made up of tire, steering swivel, wheel reduction gear, wheel hub, input yoke, slip shaft yoke, weld yoke, flange york, main reduction gear, main reduction gear universal-joint center, wheel reduction gear universal-joint center, stub line of centers, steering swivel center; Wheel limit input shaft connects main reduction gear mouth and wheel reduction gear input end, and the main reduction gear output flange leans on end face tooth and 4 bolted connections with wheel limit input shaft flange, and the wheel reduction gear semiaxis is wheel limit input shaft yoke; It is characterized in that: connecting flange fork on the main reduction gear, flange york cooperates with weld yoke, slip shaft yoke, the input yoke is fixed on the wheel reduction gear, wheel reduction gear is connected with wheel hub, the upper and lower fulcrum line of independent suspension swing arm is that stub line of centers and semiaxis crossing point of axes are wheel reduction gear universal-joint center, and stub line of centers and wheel reduction gear universal-joint center overlap with the steering swivel center during planet circular system of wheel limit; Slip shaft yoke and weld yoke axial stretching move.Wheel reduction gear is single to externally-engaged cylindrical gear or planet wheel decelerator, and wheel limit input shaft is the single cross axle universal-joint of band slip joint.
Good effect of the present utility model is to have the higher torque capability of bearing, and can satisfy military-designed vehicle and cross-country car lightweight preferably, low oil consumption, the operating needs of high reliability;

Fig. 2 is a structural representation of taking turns the limit planet circular system of the present utility model
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described: as shown in Figure 1, 2, the steering drive axle of a kind of independent suspension, single cross axle wheel-side transmission is made up of tire 1, steering swivel 2, wheel reduction gear 3, wheel hub 4, input yoke 5, slip shaft yoke 6, weld yoke 7, flange york 8, main reduction gear 9, main reduction gear universal-joint center 10, wheel reduction gear universal-joint center 11, stub line of centers 12, steering swivel center 13; Wheel limit input shaft connects main reduction gear mouth and wheel reduction gear input end, and the main reduction gear output flange leans on end face tooth and 4 bolted connections with wheel limit input shaft flange, and the wheel reduction gear semiaxis is wheel limit input yoke; It is characterized in that: connecting flange fork 8 on the main reduction gear 9, flange york 8 cooperates with weld yoke 7, slip shaft yoke 6, input yoke 5 is fixed on the wheel reduction gear 3, wheel reduction gear 3 is connected with wheel hub 4, the upper and lower fulcrum line of independent suspension swing arm is that stub line of centers 12 is wheel reduction gear universal-joint center 11 with the semiaxis crossing point of axes, and stub line of centers 12 and wheel reduction gear universal-joint center 11 overlap with steering swivel center 13 during the planet circular system of wheel limit; Slip shaft yoke 6 moves with weld yoke 7 axial stretchings.Wheel reduction gear 3 is single to externally-engaged cylindrical gear or planet wheel decelerator, and wheel limit input shaft is the single cross axle universal-joint of band slip joint.
Main reduction gear 9 output torques conduct to wheel reduction gear 3, wheel hub 4 by flange york 8, weld yoke 7, slip shaft yoke 6, input yoke 5 during work, until tire 1, realize the driving of car load.The upper and lower fulcrum of steering swivel is that independent suspension swing arm fulcrum line is a stub line of centers 12.Stub line of centers 12 is wheel reduction gear universal-joint center 11 with the semiaxis crossing point of axes, and this center overlaps with steering swivel center 13 during the planet circular system of wheel limit.Turn to and tire when beating at car load, wheel reduction gear rotates around the stub line of centers, and simultaneous wheels limit input shaft 10,11 rotates around the universal-joint center, and input yoke 5 be a connecting element, and slip shaft yoke 6 is moved by servo-actuated generation axial stretching with weld yoke 7.Single cross axle universal-joint ultimate angle is big, and turn diameter is little, and the cost new step that rises again falls car load heavily to reach in its few parts, simple, failure-free structure; Compact design is easier to take turns the layout that the limit input shaft stretches spline.
