Abstract
The utility model discloses a kind of energy-saving commercial automotive wheel rolling bearing, including axletree, wheel hub and the bearing being arranged between axletree and wheel hub, it is characterised in that：The bearing is roller bearings and ball bearing multiple, including be set up in parallel.The utility model is supported using the combination of cylinder roller bearing and centripetal class ball bearing as commercial vehicle wheel rolling, come substitute at present the commercial vehicle wheel rolling with the combination of two taper roll bearings support.Due to the coefficient of rolling friction of cylinder roller bearing and centripetal class ball bearing lower than the coefficient of rolling friction of taper roll bearing 30%.Commercial vehicle traveling tractive force, obtain energy-conservation effect can be significantly reduced.Meanwhile cylinder roller bearing undertakes radial load, centripetal class ball bearing undertakes the synthetic load from radial-axial, and the supporting structure of multiple bearings also disclosure satisfy that the bearing requirements of load.
Description
Technical field
The utility model belongs to commercial vehicle component technology field, is rolled more particularly to a kind of energy-saving commercial automotive wheel
Dynamic supporting.
Background technology
Automobile shaft and wheel need to bear larger axial load, therefore, existing commercial vehicle wheel rolling supporting
Carry out supporting wheel hub frequently with two taper roll bearing combinations.Because the ability that taper roll bearing bears radial load is greater than
Other kinds of bearing.But the contact between the roller of taper roll bearing and the Internal and external cycle of bearing contacts for face, therefore, its
Coefficient of friction is larger relative to other kinds of bearing.The tractive force for overcoming frictional force provided for automobile is also larger, unfavorable
In energy-saving.
The content of the invention
The defects of the utility model purpose is for the supporting of existing commercial vehicle wheel rolling, there is provided one kind can either
Meet axial load and radial load carrying, the energy-saving commercial automotive wheel that and can reduces commercial vehicle traveling tractive force rolls
Supporting.
The utility model to achieve the above object, adopts the following technical scheme that：
A kind of energy-saving commercial automotive wheel rolling bearing, including axletree, wheel hub and be arranged on axletree and wheel hub it
Between bearing, it is characterised in that：The bearing is roller bearings and/or ball bearing multiple, including be set up in parallel.
It is further characterized by：The roller bearing is single row roller bearing or Biserial cylindrical roller bearing；Institute
It is single-row centripetal class ball bearing or double-row class ball bearing to state ball bearing.
Preferably：The bearing includes a single row roller bearing being arranged on the inside of axletree and is arranged on described
Multiple single-row centripetal class ball bearings on the outside of single row roller bearing.
Sealing ring is provided with axletree on the inside of the single row roller bearing, to the single row roller bearing
End face is sealed.
The external diameter of the axletree dress bearing axially reduces from inboard to outside in step, the internal orifice dimension and car of the bearing
The external diameter of wheel shaft is engaged.
The utility model is supported using the combination of cylinder roller bearing and centripetal class ball bearing as commercial vehicle wheel rolling,
Come substitute at present the commercial vehicle wheel rolling with the combination of two taper roll bearings support.Due to cylinder roller bearing
Lower than the coefficient of rolling friction of taper roll bearing with the coefficient of rolling friction of centripetal class ball bearing 30%.Commercialization can be significantly reduced
Running car tractive force, obtain energy-conservation effect.Meanwhile cylinder roller bearing undertakes radial load, centripetal class ball bearing, which undertakes, to be come
From the synthetic load of radial-axial, the supporting structure of multiple bearings also disclosure satisfy that the bearing requirements of load.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
Embodiment
A kind of energy-saving commercial automotive wheel rolling bearing as shown in Figure 1, including axletree 3, wheel hub 5 and it is arranged on car
Multiple bearings between wheel shaft 3 and wheel hub 5.Bearing includes a He of single row roller bearing 6 being arranged on the inside of axletree
It is arranged on multiple single-row centripetal class ball bearings 1 in the outside of single row roller bearing 6.Single row roller bearing 6 undertakes radially
Load, multiple single-row centripetal class ball bearings 1 undertake the synthetic load from radial-axial, the supporting structure of this multiple bearings
It disclosure satisfy that the bearing requirements of load.
Sealing ring 2 is provided with the axletree 3 of the inner side of single row roller bearing 6, to the end face of single row roller bearing 6
Sealed, prevent lubricant medium to be lost in.The outside of axletree 3 is positioned by back-up ring 4 and locking nut 7 to multiple bearings
Locking.For convenient disassembly, the external diameter that axletree 3 fills bearing axially reduces from inboard to outside in step, the internal orifice dimension of bearing
It is engaged with the external diameter of axletree 3.
Claims (5)
