Free planet gear differential torque amplifying machine

Abstract

The invention discloses a free planet gear differential torque amplifying machine. By cooperation of a plurality of planet gear units which are different in transmission ratio and a driving shaft gear, the free planet gear differential torque amplifying machine realizes differential running of left and right wheels in turning of an automobile; meanwhile the output torque can be amplified by 1.56 times; the free planet gear differential torque amplifying machine is simple in structure, low in manufacturing cost and free of maintenance; the front and rear axles of the automobile are each provided with one free planet gear differential torque amplifying machine, thus ideal full-time four-drive can be realized without using a differential lock, a central differential mechanism or a transfer case; the pure mechanical structure of the free planet gear differential torque amplifying machine is free of friction, free of loss, free of delay and free of human intervention; the rotating speed ofthe torque of each wheel are adaptively adjusted; each driving wheel realizes pure rolling in turning on a paved road surface; when a wheel slip situation occurs under a special road condition, the torque can be totally transferred to the wheel and can be amplified by 56% as long as one of the wheels can provide road holding force, and thus the automobile can get rid of troubles easily.

Description

technical field [0001] The free planetary gear differential torque multiplier related to the invention belongs to the technical field of machinery and automobile manufacturing. Background technique [0002] The differential is undoubtedly a great invention, and its inventor Renault is undoubtedly a great inventor, so since the differential came out nearly a hundred years ago, it is an indispensable configuration for all modern cars; traditional The reason why the differential is known for a hundred years is that it is ingeniously conceived, so people love it, admire it, and even worship it. Today, with such advanced technology, whether it is an ordinary car or a tall luxury car They still use it, although some have been improved, but the basic principle has never departed from the original idea; however, although the traditional differential is exquisite, its fatal flaws are undeniable, mainly reflected in: it is only suitable for good When used on paved roads with poor roa...

[0002] The differential is undoubtedly a great invention, and its inventor Renault is undoubtedly a great inventor, so since the differential came out nearly a hundred years ago, it is an indispensable configuration for all modern cars; traditional The reason why the differential is known for a hundred years is that it is ingeniously conceived, so people love it, admire it, and even worship it. Today, with such advanced technology, whether it is an ordinary car or a tall luxury car They still use it, although some have been improved, but the basic principle has never departed from the original idea; however, although the traditional differential is exquisite, its fatal flaws are undeniable, mainly reflected in: it is only suitable for good When used on paved roads with poor road conditions, such as potholes, mud, ice and snow, it will not only not enhance the stability and passing ability of the car, but will have the opposite effect. When a single wheel slips or hangs in the air, Even if the other wheels are not in the air or slipping, they will completely lose their driving force and be in a static state. In order to solve this problem, people have added a differential lock to the differential. This problem has been solved, but the performance is not ideal due to the limitation of the principle. The free planetary gear differential torque multiplier of the present invention breaks through the limitation of the original differential in principle, and proposes a solution with a new concept A new solution for wheel speed difference
