Problems solved by technology

The difficulty in realizing this system is the reducer, that is, when the vehicle is driving at high speed on the road, the reducer follows, the rotation of the wheel drives the output element of the reducer to rotate, and the rotation drives the original input element of the reducer through the transmission chain of the reducer Rotation, due to the large transmission ratio of the reducer, the speed of the original input element of the reducer is very high, and the speed of the bearing at the input end also exceeds its limit speed, resulting in damage to the components, so the current reduction transmission mechanism cannot achieve

Abstract

The invention provides a planetary transmission mechanism of a variable transmission chain. The planetary transmission mechanism comprises an input shaft, sun wheels, planetary wheels, planetary carriers and tooth rings, wherein the planetary wheels are arranged on the planetary carriers; the sun wheels are connected with the tooth rings through the planetary wheels; and the planetary transmission mechanism is a one-stage, two-stage, three-stage, four-stage, five-stage, and the like, or N-stage planetary transmission mechanism, and further comprises an input end brake and a final-stage planetary carrier brake; the input end brake brakes the input shaft; the final-stage planetary carrier brake brakes the final-stage planetary carrier. The planetary transmission mechanism can provide higher driving force and cannot affect the normal running of a vehicle during follow-up; when the diameter of a wheel hub mounting and locating notch of a wheel is 280 mm, the rotating speed of each tooth ring can be up to 1,097 rpm; and when the diameter of the wheel is 1,000 mm, the allowable running speed of the vehicle is 206.7 km / h.

Description

technical field [0001] The invention relates to the field of reducers, in particular to a planetary transmission mechanism of a variable transmission chain. technical background [0002] With the increase in volume and weight of goods, and changes in road conditions, transport vehicles—such as wind turbine blades, wind turbine tower transport vehicles—encounter an unavoidable problem. When the vehicle is heavily loaded on a mountain road, it often In the case of insufficient power, and the installation altitude of wind power equipment is getting higher and higher, this problem is becoming more and more prominent. The solution on site is to borrow other vehicles, such as using a loader as auxiliary power, and sometimes it takes three loader. This is not only costly, but also a number of vehicles work together on the temporarily built rugged mountain road, and the safety is poor. The scientific solution is: increase the auxiliary drive system. [0003] The auxiliary driving ...
