Load self-adaptive type automatic gear shifting transmission mechanism

Abstract

A load self-adaptive type automatic gear shifting transmission mechanism comprises a box body, a ball screw, a power output shaft, a thrust spring, a nut, a driving gear set and a driven gear set, wherein the ball screw and the power output shaft are arranged in parallel in the box body, and the ball screw is used as a power input shaft; the nut sleeves the ball screw, and the driving gear set fixedly sleeves the nut; the driven gear set which is in engaging fit with the driving gear set fixedly sleeves the power output shaft; the thrust spring sleeves the outer side of the ball screw, and one end of the thrust spring is fixedly connected with the box body through a baffle plate; a thrust bearing fixedly sleeves the end part of the nut, and an outer ring of the thrust bearing is fixedly connected with the other end of the thrust spring through the baffle plate; two-stage variable-speed transmission is at least performed between the driving gear set and the driven gear set; each of the driving gear set and the driven gear set comprises a high-speed-grade gear and a low-speed-grade gear. With the adoption of the mechanism, the gear shifting and speed varying works can be automatically performed according to the load variation, and the gear shifting and speed varying processes are free of manual intervention, so that the operation and control are simplified.

Description

technical field [0001] The invention relates to a speed change device, in particular to a load adaptive automatic shifting transmission mechanism. Background technique [0002] For many vehicles mainly based on traditional cars and emerging mobile robots, the transmission device is an indispensable component. At this stage, if you want to use the transmission device to change gears, most of them can only rely on In terms of manual intervention, whether it is gear shifting and speed regulation by controlling mechanical components such as forks, or shifting and speed regulation directly through electronic control, neither of them is essentially free from manual intervention. On the other hand, the mechanical speed change device and the electronic speed change device relying on manual intervention are usually complicated in structure and difficult to operate, and manual pre-judgment is required when shifting and speed regulation. SUMMARY OF THE INVENTION [0003] In view of ...

Problems solved by technology

[0002] For many means of transportation based on traditional automobiles and emerging mobile robots, the transmission device is an indispensable component. Due to manual intervention, whether it is through the control of mechanical components such as shift forks for shifting and speed regulation, or directly through electronic control methods for shifting and speed regulation, both of them are not free from manual intervention in essence.

However, mechanical and electronic transmissions that rely on manual intervention usually have complex structures and are not easy to operate, and manual pre-judgment is required when shifting gears.
