A pull type clutch release device

Abstract

The present invention is a pulling type clutch separation device. The clutch housing is provided with an input shaft bearing cover along the axial direction, the input shaft bearing cover is connected with the transmission body, the release bearing is sleeved on the outer wall of the input shaft bearing cover, and the release bearing is connected to the clutch for separation. Refers to: the upper bracket of the separation fork bracket is located above the clutch housing, the lower bracket is set higher than the input shaft bearing cover, the lower bracket is set deep into the clutch housing, the lower bracket includes two spaced and parallel clamp arms, and the separation fork The upper end of the separation fork is arranged in the upper bracket of the separation fork bracket, the lower end of the separation fork is a clamping piece, the middle part of the separation fork is set in the clamp arm of the separation fork support, the separation fork shaft runs through the clutch housing, and the separation The clamp arm of the shift fork bracket and the middle part of the separation shift fork are arranged; the clamping piece at the lower end of the separation shift fork is clamped on the release bearing, and the upper end of the separation shift fork is used to connect with the push rod of the clutch booster cylinder. The smaller size solves the problem of limited torque transmission capabilities.

Description

technical field [0001] The invention relates to the technical field of clutches, in particular to a pulling clutch separation device. Background technique [0002] In the domestic heavy-duty truck industry, when a complete vehicle is matched with a manual transmission, different types of clutches are often selected according to torque and cost, that is, pull clutches or push clutches. The characteristics of the two clutches are different. The push clutch has a simple structure, low manufacturing cost and installation cost, and relatively limited torque transmission capacity; the pull clutch release device has a smaller load on the release bearing than the push clutch under the same separation force. Therefore, the torque transmission capacity is stronger, which can meet the requirements of greater torque transmission, and the lift is good and the separation is complete, but the cost is relatively high. [0003] However, with the development of science and technology, the wh...

AI Technical Summary

Problems solved by technology

The characteristics of the two clutches are different. The push clutch has simple structure, low manufacturing cost and installation cost, and relatively limited torque transmission capacity; under the same separation force of the pull clutch release device, the load on the release bearing is smaller than that of the push clutch. Therefore, the torque transmission capacity is stronger, which can meet the requirements of greater torque transmission, and the lift is good and the separation is complete, but the cost is relatively high

[0003] However, with the development of science and technology, the whole vehicle has a greater demand for power and powertrain assembly space. At present, the existing pull-type clutch release device can meet the matching requirements of high torque, but it occupies a large space, while the push-type Although the clutch has an arrangement form that meets the space requirements, the torque and strength cannot meet the requirements. Therefore, the existing clutch separation device cannot meet the load and space arrangement requirements at the same time.
