Problems solved by technology

Since the clutch assembly is composed of pressure plate, diaphragm spring, clutch pressure plate cover and connecting fasteners, etc., and because the diaphragm spring itself has elastic force, the pressure plate will protrude beyond the mounting surface of the pressure plate cover, so the installation bolts During the tightening process, under the action of the tightening force, the reaction force of the diaphragm spring will cause the final tightening torque of the bolts to be tightened successively to be different. assembly cycle), this will cause the

specific example

[0033] The supporting plate of the tooling is set into three convex plates, and the structure between the convex plates is arranged to form an angle of 120 degrees. The installation hole of the air cylinder is provided with an adjustment spring on the centering spline shaft support frame.

[0034] The stroke design of the limit guide rod is set based on the free state of the clutch and the installation height of the assembled state. When the clutch is in the free state, the limit guide rod is at the maximum stroke to facilitate the assembly of the centered spline shaft; when the clutch is assembled state, the limit guide rod is at the minimum stroke so that the clutch installation end face can fully fit the flywheel step surface.

[0035] The function of the slider is to switch the fixed claw between the free state and the clamped state; in the free state, the slider is at the forefront of the limit guide rod, that is, the fixed claw is in a freely open state; in the clamped s...

Abstract

The invention discloses a tool for clutch assembly. The tool comprises a supporting plate and a cemtered spline shaft which is arranged on the supporting plate and used for cooperating with a hollow hole of a flywheel for locating. A set of clamping jaw mechanisms for clamping a clutch on the flywheel is arranged on the supporting plate. The tool for clutch assembly is reasonable in structural design, and assembly efficiency and precision are greatly improved. Meanwhile, stress of a mounting bolt is more even, assembly consistency is good, and the problem of torque attenuation due to uneven stress of the bolt is avoided; and the problem of shaking and abnormal sounds caused by assembling inconsistency is relieved.

Description

technical field [0001] The invention relates to the technical field of clutch assembly, in particular to a tool for clutch assembly. Background technique [0002] The clutch is an important connecting part in the automobile transmission system. Its main function is to transmit and cut off the power transmission of the engine, and attenuate the vibration transmitted from the engine to the gearbox. The assembly accuracy of the clutch will directly affect its main function. [0003] Most of the existing clutches are installed by pure manual assembly. During assembly, just put the clutch driven plate and clutch cover assembly on the flywheel, and locate through the positioning pin holes. Adjust the center position of the driven disc spline and clutch cover assembly with the centering spline shaft tooling, pre-install the bolts according to the specific diagonal tightening method, and then tighten them one by one with a wrench. Since the clutch assembly is composed of pressure p...
