Embodiment Construction

[0023] see figure 1 The clutch of the present invention includes a magnetic powder clutch and a dry clutch, the magnetic powder clutch includes a magnetic powder clutch starting gear, a magnetic powder clutch active part, magnetic powder, a magnetic powder clutch excitation coil, a magnetic powder clutch follower and a magnetic powder clutch power supply slip ring, and the magnetic powder clutch starting gear is embedded in magnetic powder The active part of the clutch and the driven part of the magnetic powder clutch are connected to the active part of the magnetic powder clutch through bearings. The cavity between the active part of the magnetic powder clutch and the driven part of the magnetic powder clutch stores magnetic powder. The excitation coil of the magnetic powder clutch is fixed on the inner wall of the active part of the magnetic powder clutch to supply power. The slip ring is squeezed and connected to the active part of the magnetic powder clutch through interfer...

Abstract

The invention discloses a vehicle power compensation clutch and a clutch method, which is a power compensation clutch formed by combining a magnetic powder clutch and a dry clutch. The magnetic powder forms a magnetic powder chain under the excitation current, and the principle of transmitting torque by cutting the magnetic powder chain is combined with the working principle of the dry clutch to replace the traditional double clutch with a wet friction plate structure for vehicles. The effect of shearing the magnetic powder chain under the electromagnetic effect is used to complete the torque transmission of the magnetic powder clutch to realize power compensation, and the working principle of the dry clutch is used to realize the switching between the working and non-working states of the clutch. The linear increase and linear decrease of the excitation current of the magnetic powder sub-clutch are used to complete the switching process of the magnetic powder clutch transmission torque and the dry clutch working state. Compared with the traditional wet and dry dual clutches, the power compensation clutch for vehicles has faster response, no impact, no noise, no pollution, longer anti-slip time, and easier control.

Description

technical field [0001] The patent of the invention belongs to the technical field of automatic transmission of vehicles, and in particular relates to a power compensation clutch and a clutch method for a vehicle combining a magnetic powder clutch and a dry clutch. Background technique [0002] The earliest research on dual-clutch transmission (DCT) began in 1938. The first mass-produced dual-clutch transmission product was the DQ250 product of German Volkswagen. Dual-clutch transmission has become the target favored by major domestic and foreign OEMs and transmission suppliers. The function realization of the dual clutch transmission is based on the dual clutch, so the dual clutch becomes the key component in the research of the dual clutch transmission. [0003] At present, the dual clutch includes two forms, one is the dual clutch with wet friction plate represented by Borgwarner and the dual clutch with dry friction plate represented by LUK. [0004] Whether it is a wet ...
