Description

A dual-input vector controller

technical field

The invention belongs to the field of vector controllers, in particular to a dual-input vector controller.

Background technique

We encounter some problems in life and work. For example, cars (manual transmission), especially novice people, often encounter stalling at the start. Although automatic transmission can solve the above problems, it is expensive and has a complex structure and a high failure rate;

In terms of high-speed deceleration, especially reversible reducers, such as steam turbines, gas turbines, high-speed motors, etc., heavy-duty ball mills with inertia, converters, etc., such as heavy-duty and super-heavy locomotives, traditional disc clutches cannot be satisfied at all, traditional solutions The solution is to switch to a generator, and the electric motor increases the cost virtually.

For example, Chinese patent CN201521603U discloses a coaxial bidirectional double-shaft output reducer, which is composed of a motor, a controller, a reducer, an output hollow shaft, and an output shaft. The controller is installed at one end of the reducer to form a whole. The output shaft of the controller is sleeved in the output hollow shaft of the reducer, so that there are two output shaft drive sources on the same shaft end.

Chinese patent CN204739157U discloses a two-way output combined reducer with increased bearing capacity, including a first reducer, a second reducer, a third reducer and a combined flange. The first reducer is connected to the second reducer through the combined flange. The reducer and the third reducer are fixedly connected, the first reducer and the second reducer cooperate to drive the output hollow shaft to rotate, and the third reducer drives the output solid shaft to rotate.

Both of the above two patents can realize dual output, but not dual input. The reducer provided by the patent CN201521603U cannot meet the requirements of high-speed deceleration, and is mainly suitable for textile, pharmaceutical and other transmission machinery as a dual power source for deceleration. In heavy equipment requiring high speed deceleration. The reducer provided by the patent CN204739157U not only cannot meet the requirements of high-speed deceleration, but also requires three reducers to achieve the technical effect of double output, with complex structure and high cost.
