Abstract
A kind of automobile drive axle speed reducer assembly, is related to automobile drive axle field.Drive bevel gear is meshed with driven wheel of differential, drive bevel gear, driven wheel of differential and differential assembly are installed on reducer shell, it is characterized by: the right bearing position of differential assembly is constant value relative to the center e of reducer shell, the center right-hand offset of drive bevel gear center and reducer shell is away from difference, two kinds of reducer shells are matched with two kinds of differential assemblies, realize a variety of speed ratios of driving axis.Two kinds of reducer shells of the present invention match two kinds of differential casings, can meet same ratio coverage.Due to two kinds of reducer shells or so offset difference, a kind of same differential casing is installed in different reducer shells, it can obtain two kinds of gear locating distances, simultaneously because using two kinds of reducer shells, small speed ratio gear can be made high transmission efficiency, low noise optimization, large speed ratio gear is made high-intensitive optimization, achievees the purpose that improve designing quality, reduce cost.
Description
Technical field
The present invention relates to automobile drive axle technical field, specifically a kind of automobile drive axle speed reducer assembly.
Background technique
Currently, in automobile drive axle field, there are many speed ratios for a kind of driving axis, to meet different drive conditions.
The differential bevel wheel of different speed ratios has different locating distances.Traditional solution is to keep differential mechanism bearings at both ends spacing
It is constant, using a kind of reducer shell and a variety of differential casings, cooperated by different driven gears from different differential casings
It uses, the kind of gear is more, and the type of differential casing is also more.But it often will cause the type of differential casing in this way
Excessively, differential bearing bridges, and big, drive bevel gear guide bearing is single, retarder system poor rigidity, and then increases and be designed to
Sheet and production management cost.
Summary of the invention
In order to overcome the deficiencies of the prior art, goal of the invention of the invention is to provide a kind of automobile drive axle retarder total
At so as to improve design of part size while meeting a variety of speed ratio demands, reduction differential casing type is improved
Retarder system rigidity.
To achieve the above object, drive bevel gear of the invention is meshed with driven wheel of differential, drive bevel gear, from mantle
Gear and differential assembly are installed on reducer shell, it is characterised in that: the right bearing position of differential assembly and retarder
The distance e of the center of shell is constant value, and drive bevel gear center and reducer shell center are in vehicle left and right directions
Offset or dish is different, and two kinds of reducer shells are matched with two kinds of differential assemblies, realizes a variety of speed ratios of driving axis.
The right bearing position of differential assembly is that e subtracts drive bevel gear center with drive bevel gear center distance d
With reducer shell center in the offset or dish a of vehicle left and right directions, driven wheel of differential and drive bevel gear center are away from for c.
Drive bevel gear center is a+b in the offset or dish of vehicle left and right directions with reducer shell center, and b is two phases
The difference of the bevel gear locating distance of adjacent speed ratio, right bearing position and the drive bevel gear center distance d of differential assembly are e-a-
B, driven wheel of differential and drive bevel gear center are away from for c+b.
The present invention using two kinds of different offsets reducer shell, the differential bearing span of two kinds of reducer shells and
Relative position on reducer shell remains unchanged.Different left and right biasings is respectively adopted in two kinds of reducer shells.
Compared with prior art, the present invention traditional same reducer shell is matched four kinds of differential casings, it is changed to
Two kinds of reducer shells match two kinds of differential casings, to meet same ratio coverage.Since two kinds of reducer shells or so are inclined
It sets away from difference, similarly a kind of differential casing is installed in different reducer shells, two kinds of gear locating distances can be obtained,
Simultaneously because small speed ratio gear can be made high transmission efficiency, low noise optimization, large speed ratio tooth using two kinds of reducer shells
Crop rotation high intensity optimization, to achieve the purpose that improve designing quality, reduce design cost and production cost.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is a kind of structural schematic diagram of offset reducer shell of the present invention.
Fig. 3 is the structural schematic diagram of another offset reducer shell of the present invention.
Specific embodiment
As shown in Figure 1, drive bevel gear 1 is meshed with driven wheel of differential 3, drive bevel gear 1, driven wheel of differential 3 and poor
Fast device assembly 4 is installed on reducer shell 2, centre bit of the right bearing position of differential assembly 4 relative to reducer shell 2
Setting e is constant value, the center right-hand offset of 1 center of drive bevel gear and reducer shell 2 away from difference, two kinds of reducer shells 2 with
Two kinds of differential assemblies 4 match, and realize a variety of speed ratios of driving axis.
As shown in Fig. 2, the right bearing position of differential assembly 4 is that e subtracts initiative taper with 1 center distance d of drive bevel gear
The center right-hand offset of 1 center of gear and reducer shell 2 is away from a, driven wheel of differential 3 and 1 center of drive bevel gear away from for c.
As shown in figure 3, the center right-hand offset of 1 center of drive bevel gear and reducer shell 2 is away from being a+b, b is adjacent for two
The difference of the bevel gear locating distance of speed ratio, right bearing position and the 1 center distance d of drive bevel gear of differential assembly 4 are e-a-
B, since differential assembly 4 used is identical, it is identical at a distance from 3 back side of mantle tooth and right bearing installation end face (i.e. c with
D's and it is identical), the locating distance of driven wheel of differential 3 is c+b at this time, i.e., driven wheel of differential 3 and 1 center of drive bevel gear are away from for c+
b。
By above method, the type of differential casing part is allowed to reduce half.Since small speed ratio gear biases
Distance is supplemented by the offset or dish of reducer shell 2, and the bearing of differential assembly 4, which bridges, can reduce, and improves system stiffness,
Alleviate speed reducer assembly weight.
