Explosion-proof electromagnetic device and explosion-proof AMT clutch electromechanical device

Abstract

The invention provides an explosion-proof electromagnetic device and an explosion-proof AMT clutch electromechanical device. According to the explosion-proof electromagnetic device and the explosion-proof AMT clutch electromechanical device, a hollow sleeve is arranged in a valve body, so that an inner cavity of the sleeve is defined as an inner cavity channel; a flange-shaped valve port with an opening facing the inner cavity channel is formed on one end of the valve body; a movable piece and a fixed piece are arranged in the inner cavity channel along the channel extending direction; the fixed part is fixedly connected to the valve body at the bottom of the inner cavity channel; and the movable part is located between the fixed part and the valve port. An elastic part is also included; one end of the elastic part is fixed to the cavity wall of the inner cavity of the valve body, and the other end of the elastic part abuts against the outer contour of the movable part; when an electromagnetic coil is not electrified, the elastic part enables the movable part to make contact with the valve port for limiting and forming sealing in a pressure-bearing state or a non-pressure-bearing state, which can avoid the situation that the stress of the annular face of the bottom of the movable part is larger than the stress of the top face of the sealing piece of the inner cavity due to toolarge air inlet pressure; and therefore, the problem that the valve port is opened when the electromagnetic coil is in a non-electrified state is avoided, a transmission failure is avoided, and further derived potential safety hazards are avoided.

Description

technical field [0001] The invention belongs to the technical field of AMT gearboxes, and in particular relates to an explosion-proof electromagnetic device and an explosion-proof AMT clutch electromechanical device. Background technique [0002] Mechanical automatic transmission (also known as AMT) is to change the operating part of the original transmission into an electronically controlled actuator, in order to transform the traditional fixed shaft gear transmission through electronic technology to realize automation. It has high transmission efficiency and low production cost. Many advantages. [0003] Under the existing technology, in the automatic transmission, the electromechanical executive control core component that completes the shift function is the electromagnetic structure part, and the air compressor is the air compressor that provides air pressure to the electromagnetic structure part. The pressure provided by the air compressor will directly affect the serv...
