Abstract

The invention discloses a pull type diaphragm spring clutch pedal free stroke adaptive adjusting mechanism. The pull type diaphragm spring clutch pedal free stroke adaptive adjusting mechanism comprises a lead screw, a nut, a return spring connecting rod, a return spring and a power mechanism; the lead screw is erected on a vehicle body and is provided with an external thread on the exterior; thenut is arranged on the lead screw in a sleeving mode and internally provided with an internal thread corresponding to the external thread; one end of the return spring connecting rod is fixedly connected with the nut; one end of the return spring is fixedly connected with the other end of the return spring connecting rod, and the other end of the return spring is fixedly connected with a release bearing; the power mechanism is connected with the lead screw and used for driving the lead screw to rotate around the axle direction, can actively adjust a distance between the release bearing and a separated finger of a diaphragm spring, and the operation is convenient. The invention further discloses a pull type diaphragm spring clutch pedal free stroke adaptive adjusting method, a worm wheel rotation angle can be actively adjusted according to a magnitude of current flowing through a thin film resistor disc of a first friction plate and a second friction plate, so as to adjust the distancebetween the release bearing and the separated spring of the diaphragm spring, and the adjustment accuracy is high.

Description

technical field [0001] The invention relates to the technical field of automobile clutch free travel adjustment, and more specifically, the invention relates to a pull-type diaphragm spring clutch pedal free travel self-adaptive adjustment mechanism and adjustment method. Background technique [0002] For dry clutches, in order to ensure that the clutch can still be fully engaged during the normal wear process of the friction plate, it is necessary that when the clutch is in the normal engaged state, when the release sleeve is in the limit position, there should be a gap between the release bearing and the release finger of the diaphragm spring. Leave a certain amount of clearance. Due to the existence of the above-mentioned gap, the driver will first eliminate this gap after depressing the clutch pedal, and then he can begin to disengage the clutch. The clutch pedal travel required to eliminate this gap is called the free travel of the clutch pedal. This gap is generally ...
