Magneto-rheological clutch transmission device

Abstract

The invention relates to the technical field of power clutch transmission devices, in particular to a magneto-rheological clutch transmission device. The magneto-rheological clutch transmission device comprises a clutch disc shaft, a clutch shell carrier, magneto-rheological fluid, a clutch coil, a clutch bearing, a reversing shaft, a reversing gear, a power gear, a clutch frame shaft, a coil frame, a clutch shell, a coupling, an upper shell body and a lower shell body in an assembling mode. When a vehicle is started, the coupling inputs power to the clutch disc shaft; when the vehicle is driven away, current is input into the clutch coil, magnetorheology is changed from liquid state into solid state, the power passes the power gear and the reversing gear through the clutch disc and is transmitted to the reversing shaft; and when the vehicle is stopped, the current of the clutch coil is cut off, the magnetorheology is changed from the solid state into liquid state, and the clutch disc shaft idles and loses driving power. The magneto-rheological clutch transmission device effectively resolves the technical problems of lightweight products, simple structures, reduced materials, intelligent control, and the like, can effectively lower production cost, and provides powerful support for popularization of novel materials, novel technology and novel process and technology upgrading of the products.

Description

[technical field] [0001] The invention relates to the technical field of power clutch transmission devices, in particular to a magneto-rheological clutch transmission device and methods and applications for clutch and speed change thereof, which are suitable for small and medium-sized electric vehicles, engineering logistics vehicles, agricultural vehicles, and lifting and transporting vehicles , Marine driving devices, mechanical power devices, etc. [Background technique] [0002] Magnetorheological 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 to each other, forming a series of chain structures from one pole of the ...

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 and variable speed transmission devices required for the transmission process is relatively scattered, and there are many types of parts involved. The automation of the device Therefore, compared with the present invention, the structural parts of traditional products are large in size, the number of parts is large, and the production cost is high. Moreover, it is difficult for traditional design technology to optimize the function of the arrangement device, and it is even more difficult to support Technological upgrade of mechatronics for products

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
