Description
Technical field
The utility model relates to a kind of automotive transfer case planetary structure differential mechanism, belong to vehicle driveline
Gear drive part.
Background technology
Automotive transfer case product in the market, its differential design divide satellite differential（Divide and turn round ratio 1:2）, cone
Gear differential mechanism（Divide and turn round ratio 1:1）, above two differential mechanism the problem of interchangeability deficiency be present in same transfer case product, it is necessary to
Change transfer case body class.
The content of the invention
The purpose of this utility model is to overcome the shortcomings of the prior art, and offer is a kind of rational in infrastructure compact, makes
With convenient and reliable, product interchangeability is not influenceed, bearing torque can be improved, reduces rotational noise, transmission capacity is higher, and transmission is more
Steadily, a point torsion ratio 1 can be realized:1 automotive transfer case planetary structure differential mechanism.
The purpose of this utility model is completed by following technical solution, and a kind of automotive transfer case planetary structure is poor
Fast device, it is mainly made up of planetary gearsets, planet axis, sun gear, planet carrier, and the first described planetary gear empty set is first
In planet axis, for the second planetary gear empty set in the second planet axis, two planet axis are separately fixed at the first planet carrier 1 and the second row
On the same circumference of component of carrier, and multigroup planetary gear and multigroup planet axis, the first described sun gear and the first row be present
Star gear engages, and the second described sun gear engages with the second planetary gear.
As preferred：The first described planetary gear and identical, described the first sun gear of the second planetary number of teeth
Identical with the number of teeth of the second sun gear, power inputs through the first planet carrier and the second planet carrier, by the first sun gear and second too
Sun wheel exports respectively, realizes a point torsion ratio 1:1 differential output.
As preferred：The first described planetary gear engages with two planetary gears respectively, planetary gear respectively with two
Planetary gear engages, and inside configuration has that planetary gear is multigroup, planetary gear is multigroup, realizes dynamic branch.
The utility model eliminates gear ring part, have it is rational in infrastructure compact, it is easy to use and reliable, do not influence product exchange
Property, bearing torque can be improved, reduces rotational noise, transmission capacity is higher, and transmission is more steady, can realize a point torsion ratio 1:1 grade spy
Point.
