Planetary type main clutch for automobile

Abstract

The invention discloses a vehicular planetary type main clutch device, which comprises a power input shaft, a power output shaft, a driving friction disk and a driven friction disk, the driving friction disk is fixedly arranged on the power input shaft, and the vehicular planetary type main clutch device further comprises a planetary gear train which includes a sun gear, a planet gear and an outer gear ring. The driving friction disk is fixedly arranged on a driven shaft, the sun gear is fixedly arranged on the power input shaft, the outer gear ring is fixedly connected with the power output shaft, and the planet gear is rotationally engaged with a planet carrier. At operating time, power is transmitted to the planet carrier through a one way clutch from the driven shaft. The vehicular planetary type main clutch device reduces the rotational speed difference between the driving friction disk and the driven friction disk of the clutch in starting process, reduces the starting jointing time of the clutch, reducing the slip energy, simultaneously reducing the vehicle impact and enabling the slip energy and the vehicle impact to sufficiently coordinate because the rotational speed difference of the driving friction disk and the driven friction disk is reduced, and the jointing speed requirement is reduced. The vehicular planetary type main clutch device not only increases the vehicle ride comfort in the staring process, but also can prolong the service life of the main clutch.

Description

technical field [0001] The invention relates to a vehicle clutch device, in particular to a vehicle planetary main clutch device. Background technique [0002] The clutch device is a necessary structure of the vehicle, and its structure is mainly composed of two parts: the driving friction plate of the clutch and the driven friction plate. Wherein the active friction plate is connected with the output end of the power output device such as the engine, and the driven friction plate is connected with the input shaft of the gearbox. [0003] Before the vehicle starts, the active friction plate and the driven friction plate are in a separated state. With the engagement of the clutch, the friction torque increases through the increase of the pressing force between the main and driven friction plates, and the driven friction plate starts to rotate, and the friction torque also passes through The transmission and other mechanisms drive the vehicle to start running until the main a...

AI Technical Summary

Problems solved by technology

Among them, the sliding friction work is mainly affected by the rotational speed difference between the main and driven friction plates of the clutch, while the impact degree is closely related to the engagement speed of the clutch. Smaller and the vehicle starts smoothly, but the sliding friction work is relatively large and the clutch wear is relatively large, which reduces the service life of the clutch; on the contrary, if the clutch engagement time is short, the impact of the vehicle body starting is relatively large and the vehicle comfort is reduced. However, the friction work is relatively small and the clutch wear is low, which can ensure the service life of the clutch
