Abstract
The utility model relates to a novel disconnection type driving axle housing, which belongs to the technical field of automotive transmission. The utility model is mainly composed of an end face of a main speed reducer shell, connecting disks, ventilating holes, a pin shaft hole of a differential lock, a sensor hole, an oil filling screw plug hole, an oil draining screw plug hole, a back cover, a swing arm installing support, an output port, etc., wherein the end face of the axle housing is connected with the end face of the main speed reducer shell through the screw bolts, and the connecting disks on both sides of the axle housing are fixed on the automobile frame through the screw bolts; the lower end of the axle housing is symmetrically provided with two brackets with through holes, and the bracket is provided with a suspended lower swing arm shaft; a lower swing arm swings around the shaft; a communicated shaft in the middle section of the axle is connected by the output port on the back cover. The utility model can reduce vibration and carriage inclination when the automobile runs on the uneven road surface to the max, improve automobile running smoothness and average traveling speed, reduce the dynamic load on the wheels and the automobile axle and damage of components, and improve reliability and service life.
Description
Technical field
The utility model relates to a kind of independent suspension heavy off-road vehicle and casts integral housing with breakaway-element, belongs to the automotive transmission technical field.
Background technology
Heavy-duty truck is one of main load-carrying element on the automobile with the rigid drive axle axle housing, plays a part the loading of supporting automobile, and load is passed to wheel.The tractive force, braking force, side force and the vertical force that act on the drive wheels also are to pass on suspension and the vehicle frame through axle housing.So axle housing is a load member is again force transmission element, be again the shell of main reduction gear, diff and drive wheels driving device (semiaxis) simultaneously.Therefore, it can not satisfy the requirement of some heavy off-road vehicle to high ride, high maneuverability.
Summary of the invention
The utility model is at the deficiencies in the prior art, provides that a kind of riding comfort is good, road-holding property is high, can satisfy the novel broken drive bridge axle housing that independent suspension heavy off-road vehicle dual-ratio reduction drive axle is used.
The utility model is finished by following technical measures.
This broken drive bridge axle housing mainly is made up of main shell installation end face, terminal pad, air extractor vent, differential locking-device pin shaft hole, gauge hole, oiling spiro pluging hole, drain screw hole, bonnet, swing arm mounting bracket, the output port etc. of subtracting.Wherein, the layout in the air extractor vent on the axle housing, differential locking-device pin shaft hole, gauge hole and oiling spiro pluging hole, drain screw hole, identical with the layout of prior art press axle housing, it is characterized in that axle housing end face and final drive casing end face are by bolted connection, axle housing is fixed on the vehicle frame by the terminal pad of bolt with its both sides, be arranged with the support of two tool through holes in the lower end of axle housing, adorning and hanging arm shaft down, following swing arm is around this axle swing, and the thru shaft in bridge stage casing is connected by the output port on the bonnet.
Axle housing and bonnet are cast as one.
Axle housing is an inblock cast, wall thickness 15mm-18mm.
The utility model by the bolted connection form, makes the axle housing effect of crossbeam of having held concurrently with axle housing end face and final drive casing end face.In order to improve the strength and stiffness of axle housing, axle housing and bonnet are cast as one, for swing arm under the independent suspension is installed, be cast with the support of two tool through holes in the lower end of axle housing symmetry, adorning and hanging arm shaft down, following swing arm is around this axle swing, and the thru shaft in bridge stage casing is connected by the output port on the bonnet.The utility model is limit by the space according to the breakaway-element axle housing, the shape more complicated of axle housing adopts the cast steel axle housing to make complexity as required and desired shapes, wall thickness can change, can obtain desirable distribution of stress, its strength and stiffness are all bigger, reliable operation.And broken drive bridge axle housing and independent suspension adapt, can make the drive axle unsprung weight less, drive wheels and the ground-surface situation and better that contacts to the comformability of various landform, vibration in the time of can farthest reducing automobile and travel on uneven road surface and compartment tilt, improve ride of vehicle and average ground speed, reduce on wheel and the vehicle bridge live load and the damage of part, improve its reliability and service life.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model birds-eye view;
Fig. 3 is the section-drawing of Fig. 1.
Wherein, 1, the main shell that subtracts installs end face, 2, terminal pad, 3, air extractor vent, 4, the differential locking-device pin shaft hole, 5, gauge hole, 6, refuel spiro pluging hole, 7, the drain screw hole, 8, bonnet, 9, swing arm mounting bracket, 10, output port
The specific embodiment
Embodiment: structure as shown in Figure 1-Figure 3, the drive axle axle housing is made by the refined steel inblock cast.Axle housing end face 1 adopts original bolted connection form with the final drive casing end face, and axle housing directly is rigidly fixed on the vehicle frame with bolt by the terminal pad 2 on its both sides, so the axle housing effect of crossbeam of can having held concurrently.The layout in axle housing upper vent hole 3, differential locking-device pin shaft hole 4, gauge hole 5 and oiling spiro pluging hole 6, drain screw hole 7 is identical with the layout of Steyr press axle housing.In order further to improve the strength and stiffness of axle housing, here axle housing and bonnet 8 are cast as one.For swing arm under the independent suspension is installed, be cast with the support 9 of two tool through holes in the lower end of axle housing symmetry, to adorn and hanging arm shaft down, following swing arm is around this axle swing, and the thru shaft in bridge stage casing is by 10 connections of the output port on the bonnet.In order further to improve the strength and stiffness of axle housing, here axle housing and bonnet 8 are cast as one.Axle housing wall thickness 16mm can satisfy the requirement that nominal axes is carried 13 tons of quality.
Claims (3)
1, a kind of novel broken drive bridge axle housing, mainly end face is installed by the main shell that subtracts, terminal pad, air extractor vent, the differential locking-device pin shaft hole, gauge hole, the oiling spiro pluging hole, the drain screw hole, bonnet, swing arm mounting bracket, output port is formed, it is characterized in that, axle housing end face and final drive casing end face pass through bolted connection, axle housing is fixed on the vehicle frame by the terminal pad of bolt with its both sides, be arranged with the support of two tool through holes in the lower end of axle housing, adorning and hanging arm shaft down, following swing arm is around this axle swing, and the thru shaft in bridge stage casing is connected by the output port on the bonnet.
