Magneto-rheological clutch, brake and variable speed control drive assembly device

Abstract

The invention belongs to the technical field of drive assembly devices, in particular to a magneto-rheological clutch, brake and variable speed control drive assembly device, which is formed by assembling a coupling, an upper shell, a lower shell, a clutch coil, a clutch shell, a brake coil, a brake shell, a clutch holder shaft, a clutch disc shaft, a clutch bearing, a brake pad bracket, a reversing bearing, a reversing gear, a reversing shaft and a power gear; when a vehicle starts, the coupling inputs power to the clutch disc shaft; when the vehicle runs, current is input into the clutch coil, a magneto-rheological material is subjected to phase change, and the power is transmitted to the reversing shaft from the clutch disc shaft through the power gear and the reversing gear; and when the vehicle is braked, the current input into the clutch coil and the brake coil is cut off, the magneto-rheological material is subjected to phase change, and the brake pad bracket and the reversing shaft are in a brake locking state. The device solves technical problems to achieve light-weight product, simple structure, material reduction and intelligent control, and powerful support is provided for promoting new materials, new technologies, new processes and technical upgrade of products.

Description

[technical field] [0001] The invention relates to the technical field of transmission assembly devices, in particular to a transmission assembly device controlled by a magneto-rheological clutch, a brake, and a transmission, and a transmission method and application thereof, which are suitable for small and medium-sized electric vehicles, engineering logistics vehicles, and agricultural vehicles , Lifting and handling vehicles, marine driving devices, mechanical power devices and other necessary supporting ranges of use. [Background technique] [0002] Magneto-rheological fluid is a new type of phase-change material. It is a magnetic particle suspension mixed with high magnetic permeability and low hysteresis (micron or even nanoscale) soft magnetic particles and non-magnetic liquid. When there is no magnetic field, the suspended particulate iron particles move freely with the liquid; when a magnetic field is applied, these suspended particulate iron particles are attracted ...

AI Technical Summary

Problems solved by technology

[0004] The traditional power transmission, load drive and mechanism control basically adopt the form of separate installation to configure the relevant mechanical devices. The design distribution of the clutch, brake and speed change transmission devices required for the transmission process is relatively scattered, and the types of parts involved are very complicated. , the degree of automatic control of the device is very low. Therefore, compared with the present invention, the structural parts of the traditional product are large in size, the number of parts is large, and the production cost is high. Moreover, it is difficult for the traditional design technology to perform the functions of the sorting device. Optimize the combination, it is more difficult to support the technical upgrade of the mechatronics of the product

At present, no precedent has been found to integrate the above-mentioned sorting device into a power transmission assembly device and apply magnetorheological control technology to control and manage the power transmission function process
