Description
Technical field
The field of automobile that the utility model relates to, especially a kind of passenger vehicle singl-reduction axle.
Background technology
In the prior art, known technology is the end that drive axle assembly is positioned at automotive transmission, and its basic training is with being to increase by transmission shaft to transmit the torque coming, and to left and right driving wheel, and makes left and right driving wheel have differential function torque distribution; Meanwhile, drive axle also will bear vertical force, longitudinal force and the transverse force and the moment thereof that act on road surface and vehicle frame.Passenger vehicle in the market with singl-reduction axle be mainly adopt 153 bridge masters subtract, carry little, noise is higher, this is the existing weak point of prior art.
Summary of the invention
The purpose of this utility model, is exactly for the existing deficiency of prior art, and the technical scheme of a kind of passenger vehicle singl-reduction axle is provided, the drive axle of this scheme, and input end adopts upper offset to arrange, and load-carrying capacity is strong, and noise is low; Wheel limit assembly adopts hub-bearing unit, and load-carrying capacity is strong, conducts oneself with dignity low, can meet high-end Bus & Coach Design requirement.
This programme is achieved by the following technical measures: a kind of passenger vehicle singl-reduction axle, comprise axle housing, the main assembly that subtracts, upper thrust rod seat, the feature of this programme is: upper thrust rod seat is fixed on axle housing top, the main middle part that subtracts assembly and be fixed on axle housing, is provided with mounting plate and bottom plate on the main axle housing that subtracts assembly both sides, is provided with wheel limit structure in the both sides of axle housing; Described wheel limit structure comprises the wheel hub with semiaxis, described semiaxis is arranged on the two ends of axle housing, wheel hub is arranged on axle housing by hub-bearing unit, on axle housing, be provided with the thrust washer for locating wheel hub bearing unit, there is brake wheel in wheel hub external stability, on axle housing, be also provided with braking flange, between braking flange and brake wheel, be provided with brake assembly.
Described wheel hub and semiaxis are fixed by semiaxis bolt of rear end plate.。
Described thrust washer is fixed on axle housing by jam nut.
Described braking flange and brake assembly are fixed by drg bolt of rear end plate.
Described axle housing is steel plate housing.
Described brake wheel and wheel hub are fixed by wheel bolt.
The beneficial effect of this programme can be learnt according to the narration to such scheme, because thrust pole seat in this scheme is fixed on axle housing top, simultaneously towards car load rear, has met the installation requirement of bus engine postposition to drive axle; Wheel hub is assemblied on axle housing by hub-bearing unit 1, and with thrust washer and jam nut locking positioning, wheel hub and semiaxis are integrated by bolts assemblies, and power is passed to wheel hub from semiaxis like this; Brake assembly is by bolts assemblies on braking flange, and brake wheel is carried out braking function by there is friction with brake assembly.
As can be seen here, the utility model compared with prior art, has substantive distinguishing features and progress, and the beneficial effect of its enforcement is also apparent.
