Slow-release controllable clutch

Abstract

A slow-release controllable clutch is majorly composed of a planet wheel mechanism and a control mechanism. An outer gear ring or a gear, as a control part, is fixedly connected to a planet carrier or an output shaft of the planet wheel mechanism in the mode that the outer gear ring or the gear cannot rotate relatively. The control part is engaged with a connection gear fixedly connected to a control mechanism drive shaft. The control mechanism is a controllable piston hydraulic device. The drive shaft is a crankshaft. The control mechanism is structurally characterized in that the connection gear is fixedly installed on the crankshaft; a crank on the crankshaft is movably connected with a connecting rod in a matched mode; the other end of the connecting rod is movably connected with a piston in a matched mode; the piston is located in a hydraulic cylinder; a circulating loop enables the upper part and the lower part of the hydraulic cylinder to communicate; and a flow control valve is installed on the circulating loop.

Description

technical field [0001] The invention relates to a clutch, in particular to a slow release controllable clutch. Background technique [0002] The clutches used in existing motor vehicles are basically friction clutches that have been used for many years. The advantages of this clutch are simple structure, high transmission efficiency, mature and reliable technology, and its disadvantage is that when combined, the transmitted torque changes nonlinearly. , resulting in a large speed difference during the shifting process, resulting in a strong shifting impact. For overcoming this deficiency, there have been different technical solutions, as the invention of CN1271355C, the notification number discloses a kind of constant mesh clutch. The caliper with variable control force is used to control the friction disc, so as to achieve the purpose of making the clutch controllable. Although this solution can control the clutching and disengaging of the clutch, it is difficult to achie...

Problems solved by technology

[0002] The clutches used in existing motor vehicles are basically friction clutches that have been used for many years. The advantages of this clutch are simple structure, high transmission efficiency, mature and reliable technology, and its disadvantage is that when combined, the transmitted torque changes nonlinearly. , resulting in a large speed difference during the shifting process, resulting in a strong shifting impact

Although this solution can control the clutch clutch, it is difficult to achieve the desired effect in specific applications because the relationship between the control force exerted on the caliper and the friction disc speed is extremely difficult to produce a linear relationship.
