Description
Technical field
This utility model relates to automobile steering system technical field, is specially a kind of automobile steering system with defeated
Shaft.
Background technology
Dynamic steering system be Audi used steering technology address, from principle from the point of view of be still that
Use the principle of superposition, but the structure used but system with BMW and Toyota be as different as light from darkness,
Its core component is a set of electric-control system with harmonic gear drive mechanism as core.Harmonic gear is to utilize
Controlled elasticity deformation (alteration of form) of flexbile gear, just wheel and the relative motion of wave producer, particularly flexbile gear
Realize motion and power transmission.The principle changing turning rate is the side set motion of harmonic wave legacy system.
The power shaft of steering wheel of ining succession is connected with flexbile gear (slim annular gear), has flexible ball bearing in it, in
The heart is motor-driven elliptic rotor, and be connected with output shaft is the firm wheel of outer ring surface composition, at rotor quilt
During locking (motor is not powered on or breaks down), steering turning rate keeps constant.And during motor drives
When centre rotor rotates, flexbile gear can be driven to rotate, when rotor and flexbile gear rotating Vortex, due to the tooth of flexbile gear
The number of teeth of number wheel more firm than outer shroud is little, so just the rotational angle of wheel will be more than flexbile gear, makes steering angle quilt
Amplify, and when rotor inverts, it becomes possible to play the effect reducing steering angle.
What on existing servo steering system, output shaft was taked is 8 spiral rolling track structures, because its processing is multiple
Miscellaneous, measure loaded down with trivial details, bring higher cost (cutter, manpower, equipment) and time (to add to processing and inspection
Work, measure packet) waste；And 8 spiral fluted output shaft loads onto slide block, steel ball, power shaft
Rear stress point is many, interferes with each other, and assembly failure is many.This is accomplished by the output of a kind of novel steering
The shortcoming that axle solves prior art.
Utility model content
The purpose of this utility model is to provide a kind of automobile steering system output shaft, to solve the above-mentioned back of the body
The problem proposed in scape technology.
For achieving the above object, this utility model provides following technical scheme: a kind of automobile steering system is used
Output shaft, including power transmission shaft, described power transmission shaft surface is socketed with driven gear, on the right side of described driven gear
Being provided with axle bed, the right side of described axle bed is provided with indent two sides width, and indent two sides width is fixed on power transmission shaft
Surface, the right side of described indent two sides width is separately installed with first planet gear and the second planetary gear, and
First planet gear is positioned at the second planetary left side, is provided with the shaft shoulder on the right side of described second planetary gear,
On the right side of described power transmission shaft, top is provided with spline, and described power transmission shaft surface is also equipped with shaft key sleeve.
Preferably, described power transmission shaft surface has groove milling.
Preferably, described spline is involute spline.
Preferably, it is provided with cylindrical pin with external thread between described first planet gear and the second planetary gear.
Compared with prior art, the beneficial effects of the utility model are: this automobile steering system output shaft,
Bigger knuckle is used, to reduce axle in use by the shadow of too much concentrated stress at the shaft shoulder
Ring, in the groove milling that power transmission shaft surface has, utilize CNC milling cutter, the weakening of countershaft body can be slowed down,
Involute spline can reduce the stress at tooth root, and indent two sides width uses a forging technology molding,
Improve the precision of product, make power transmission shaft can closely cooperate when assembling.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation；
Fig. 2 is this utility model left view；
Fig. 3 is this utility model profile；
Fig. 4 is this utility model spline structure schematic diagram.
In figure: 1 power transmission shaft, 2 driven gears, 3 axle beds, 4 indent two sides width, 5 first planet gears,
6 second planetary gears, 7 shaft shoulders, 8 splines, 9 groove millings, 10 shaft key sleeves.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, to the technology in this utility model embodiment
Scheme is clearly and completely described, it is clear that described embodiment is only this utility model one
Divide embodiment rather than whole embodiments.Based on the embodiment in this utility model, this area is common
The every other embodiment that technical staff is obtained under not making creative work premise, broadly falls into this
The scope of utility model protection.
Referring to Fig. 1-4, this utility model provides a kind of technical scheme: a kind of automobile steering system exports
Axle, including power transmission shaft 1, described power transmission shaft 1 surface is socketed with driven gear 2, and described driven gear 2 is right
Side is provided with axle bed 3, and the right side of described axle bed 3 is provided with indent two sides 4, and indent two sides 4 is fixed
On power transmission shaft 1 surface, the right side on described indent two sides 4 is separately installed with first planet gear 5 and
Two planetary gears 6, and first planet gear 5 is positioned at the left side of the second planetary gear 6, described second planet
Being provided with the shaft shoulder 7 on the right side of gear 6, on the right side of described power transmission shaft 1, top is provided with spline 8, described power transmission shaft
1 surface is also equipped with shaft key sleeve 10.Described power transmission shaft 1 surface has groove milling 9.Described spline 8 is for gradually to open
Line spline.It is provided with cylindrical pin with external thread between described first planet gear 5 and the second planetary gear 6.
Operation principle: the shaft shoulder 7 uses bigger knuckle, it is possible to reduce output shaft is subject in use
The impact of too much concentrated stress, the spline 8 that top is arranged on the right side of power transmission shaft 1 is involute spline,
The stress at tooth root can be reduced, use the indent two sides 4 of a forging technology molding, can improve defeated
The precision of shaft, makes output shaft can closely cooperate when assembling, and power transmission shaft 1 surface CNC milling cutter is opened
