Abstract
The invention relates to a portal housing of a portal axle for a vehicle, with two side walls, between which a portal drive with a driving wheel and a driven wheel and one or more intermediate wheels are optionally arranged. With an oil sump in the bottom of the portal housing in which the driven wheel in rotation to a coaxially to the rotational axis of the output gear extending output shaft is connected, which is characterized by a coaxial opening a rotationally fixed to one side wall connected hub carrier extends and the driven wheel is rotatably mounted on a Abtriebsradlagerung on the gantry housing. At least the inner wall one of the side walls has a flat surface which is formed at least largely without protruding from their plane elevations, wherein between the end faces of the drive wheel driven wheel and is optionally formed between the wheels and the free surface elevation of the inner wall of the side wall an approximately equal wider lubricating gap.
Description
Technical field
The present invention relates to a kind of gate-type housing of the gate-type axletree for vehicle, this gate-type housing has two sidewalls, the gate-type actuator with drive wheel and flower wheel and possible one or more breast wheels is furnished with between these two sidewalls, this gate-type housing has oil pan tray in lower region thereof, wherein, flower wheel torsionally with relative to the axially extending driven shaft of the rotation axis of flower wheel is connected, this driven shaft extends through the coaxial openings of the wheel hub frame that be connected antitorque with sidewall and flower wheel is pivotally bearing on gate-type housing by flower wheel bearing set.
Background technology
In this kind of gate-type housing, by flower wheel, driven shaft is driven in rotation by drive wheel.At this, drive wheel to immerse in the fluid of oil pan tray and carries fluid at this by its outside face, and this fluid to be carried in flower wheel upper area by the outside face of flower wheel and to be carried to further here wheel hub frame and to lubricate gate-type actuator thus.
Summary of the invention
The object of the invention is to realize the gate-type housing that type is mentioned in a kind of beginning, produce the churning loss come because of fluid eddy current little as far as possible when its work.
This object realizes therefrom according to the present invention, namely the inwall of at least one sidewall has smooth surface, this surface is configured to the jut do not protruded from its plane at least to a great extent, wherein, drive wheel, flower wheel and the side of possible breast wheel and the inwall of sidewall without protrusion surface between form approximate wide lubrication gap.
By this structural scheme, in the lubrication gap between the side and the inwall of one or two sidewall of the gear at gate-type actuator, form the oil film evenly flowed not having eddy current at least to a great extent upward.The avoiding churning loss without eddy current significantly and make thus more effectively to utilize application driving energy in the drive of this oil film.
In order to the fluid input wheel hub frame inside of purposively will carry upward in gate-type housing, fluid guiding device can guide to the inside of wheel hub frame from the upper area of gate-type enclosure interior.
Thus, fluid can arrive flower wheel bearing set well on the one hand and also arrive the bearing set of the wheel hub be bearing on wheel hub frame on the other hand by wheel hub frame.
When at least the unpolarized sidewall of its inner wall surface has one or more reinforcement jut outside it, the weight of gate-type housing can be made to reduce and make required driving to reduce thus.
Thus, sidewall can have less wall thickness and steadiness needed for it by strengthen jut obtain.Strengthen jut and avoid fluid eddy current in outside instead of at the arrangement form of inner side.Strengthen jut and be preferably strengthening rib.
By being completely configured to smooth towards inwall without the side of protrusion surface by drive wheel, flower wheel and possible breast wheel, define particularly non-vortex fluid film.
Accompanying drawing explanation
Embodiments of the invention are shown in the drawings and will be further illustrated hereinafter.Wherein:
Fig. 1 shows a part for the lateral plan of the gate-type shell area of gate-type axletree with elevation profile,
Fig. 2 shows the lateral plan of the gate-type housing of the gate-type axletree according to Fig. 1 with elevation profile.
Detailed description of the invention
Shown gate-type axletree has gate-type housing 1, is furnished with the gate-type actuator with drive wheel 2 and flower wheel 3 in this gate-type housing 1.Drive wheel 2 immerses in the fluid of the oil pan tray 4 be configured in the lower area of gate-type housing 1 with lower region thereof.
On the right part that flower wheel 3 is torsionally arranged in driven shaft 5 and with the coaxial openings 6 of its left region through the wheel hub frame 7 be torsionally connected with gate-type housing 1.
Gate-type housing 1 has left side wall 8 and right side wall 9.
Flower wheel 3 has Driven hub 10, and flower wheel 3 is arranged on driven shaft 5 by means of this Driven hub 10.By means of the end of protruding coaxially relative to the both sides of flower wheel 3 of Driven hub 10, flower wheel 3 rotatably supports respectively by antifriction-bearing box 11,12.Right side antifriction-bearing box 12 is arranged in the recess 14 of the inwall 17 being arranged in right side wall 9, antifriction-bearing box on the right side of this is accommodated in this recess 14 and does not stretch into the inside of gate-type housing 1 to a great extent.
Left side antifriction-bearing box 11 is arranged in the recess 13 of the right part being arranged in wheel hub frame 7, antifriction-bearing box on the left of this is accommodated in this recess 13 and does not stretch into the inside of gate-type housing 1 to a great extent.
Drive wheel 2 is torsionally arranged on the left part of axle drive shaft 15, and the through hole 16 that this axle drive shaft 15 is passed in right side wall 9 extend into gate-type housing 1 from outside.On bearing 18 outside the inside that axle drive shaft 15 can be rotated to support on gate-type housing 1.The left part of axle drive shaft 15 extend in the recess 19 in the inwall 20 of left side wall 8.
Inwall 17 and 20 extends parallel to each other and substantially flat.Lubrication gap 23 is formed between inwall 17 and 20 and the side 21,21 ' of flower wheel 3 and between inwall 17 and 20 and the side 22,22 ' of drive wheel 2.
The fluid being transported to the upper area 24 of gate-type housing 1 when drive wheel 2 and flower wheel 3 work especially by lubrication gap 23 by oil pan tray 4 arrives antifriction-bearing box 11 by fluid guiding device 25 and arrives the coaxial openings 6 of wheel hub frame 7 by this antifriction-bearing box 11 and lubricate driven shaft 5.
