Problems solved by technology

The fork structure adopts the principle of leverage to realize the force transmission. Since the pull clutch is mostly used in medium-sized and heavy-duty vehicles, the transmission torque of the fork is large, the impact noise is large, the sensitivity is not good, the installation is difficult, and the use comfort is not good, etc. shortcoming

Embodiment Construction

[0026] Refer to attached Figure 1~2 , the pull-type self-aligning hydraulic release bearing sub-cylinder unit includes an installation connection mechanism, an alignment mechanism, a bearing mechanism, a hydraulic sub-pump mechanism, a dust-proof mechanism and an auxiliary mechanism; the installation connection mechanism is composed of a clutch connection part and a gearbox connection part, Including separation pull ring 4, clamp 16, fixed ring 3 and helical compression spring 5; the centering mechanism includes self-aligning spring piece 13, self-aligning spring piece supporting ring 14 and self-aligning spring piece fixing ring 15, self-aligning spring piece It is the main part of the centering mechanism. The centering function is determined by the axial force generated after the part is compressed. The self-aligning spring fixing ring 15 and the self-aligning spring piece support ring 14 mainly play a fixed role; the bearing mechanism includes the outer Ring 1, inner ring ...

Abstract

The invention relates to a pull-type self-aligning hydraulic release bearing sub-pump unit, which is used for heavy-duty trucks and applicable to heavy-duty commercial vehicles and passenger vehicles with D430 pull-type clutches and belongs to the technical field of automobile bearings. The pull-type self-aligning hydraulic release bearing sub-pump unit comprises a mounting connection mechanism, an aligning mechanism, a bearing mechanism, a hydraulic sub-pump mechanism, a dustproof mechanism and an auxiliary mechanism. The mounting connection mechanism consists of a clutch connecting part and a gearbox connecting part and comprises a separation pull ring, a hoop, a fixing ring and a spiral compression spring. The aligning mechanism comprises an aligning spring plate, an aligning spring plate supporting ring and an aligning spring plate fixing ring. The bearing mechanism comprises an outer ring, an inner ring, a retainer, a steel ball and a bearing seal ring. The hydraulic sub-pump mechanism comprises a cylinder block, a piston, a first leather ring, a second leather ring, a piston ring and a cylinder block ring. The dustproof mechanism comprises an outer dust cover and an inner dust cover, and the auxiliary mechanism comprises an oil inlet screw, a pressure plate and an outer cover.

Description

technical field [0001] The pull-type self-aligning hydraulic release bearing sub-pump unit of the invention relates to a pull-type self-aligning clutch release bearing sub-pump unit for heavy vehicles. The pull-type self-aligning hydraulic release bearing sub-cylinder unit is suitable for heavy-duty commercial vehicles and passenger vehicles using D430 pull clutches. It belongs to the technical field of automobile bearings. Background technique [0002] The traditional working principle of automobile clutch is divided into two types, one is the mechanical pull bar mechanism: step on the clutch pedal, pull the shift fork through the pull bar, the shift fork pushes or pulls the release bearing to separate the clutch driven disc, and cuts off the power of the engine output, so as to realize the clutch function. The other is to use a hydraulic transmission mechanism: step on the clutch pedal, the power is transmitted to the clutch master cylinder, the master cylinder outputs o...
