Repairing device of clutch cup of vehicle transmission

Abstract

The invention relates to the technical field of vehicle transmission machining, in particular to a repairing device of a clutch cup of a vehicle transmission. The device comprises a brush mechanism, arotating mechanism and a guide mechanism; the rotating mechanism is connected with an outer motor, the brush mechanism comprises a brush take up and payoff sleeve, a take up and payoff pushing rod, abrush take up and payoff disc and a brush rod; an avoiding groove is formed in the brush take up and payoff sleeve, one end of the take up and payoff pushing rod is hinged to the avoiding groove, thebrush take up and payoff disc is in a similar triangular shape, the other end of the take up and payoff pushing rod is hinged to the first corner end of the brush take up and payoff disc, the secondcorner end of the brush take up and payoff disc is hinged to one end of the brush rod, the other end of the brush rod is connected with a first hinge shaft, and the first hinge shaft is sleeved with afirst positive and negative brush. The outer motor drives a rotating mechanism to move, the rotating mechanism drives the brush mechanism to move, and in the brush mechanism, the brush rod drives thefirst positive and negative brush to brush the inner wall of the clutch cup.

Description

technical field [0001] The invention relates to the technical field of automobile gearbox processing, in particular to a repair device for a clutch cup of an automobile gearbox. Background technique [0002] The clutch is installed between the engine and the transmission, and is an assembly directly connected with the engine in the car drive train. Usually, the clutch is installed together with the flywheel set of the engine crankshaft, which is the part that cuts off and transmits power between the engine and the vehicle transmission system. During the whole process of the car from starting to normal driving, the driver can manipulate the clutch as needed to temporarily separate or gradually engage the engine and drive train to cut off or transfer the power output from the engine to the drive train. Its function is to make the engine and the transmission gradually engage, so as to ensure the smooth start of the car; temporarily cut off the connection between the engine and...

AI Technical Summary

Problems solved by technology

[0003] The clutch cup is an important structure on the clutch. During the remanufacturing process of the automatic gearbox, after the automatic gearbox is disassembled and stored for a period of time, problems such as rust and oxidation will occur on the inner hole wall and surface of the clutch cup in the air. Assembly can contaminate fluid and cause transmission malfunction

[0004] In the existing technology, manual hand-held sandpaper is used to repair the inner hole wall of the clutch cup, which is inserted into the clutch cup, and the arm is repeatedly rotated for repair. This method is labor-intensive and low in production efficiency. The repair effect of the surface is poor

[0005] The patent name is a Chinese invention patent for a hydraulic and pneumatic cylinder inner wall repair device (the authorized announcement number is CN201916284U, and the application date is January 21, 2011), which discloses that the repair device includes a pulling screw, a spline shaft, and a pulling wire There is a connector between the bar and the spline shaft, and the spline shaft is successively equipped with a turning head, a rolling bearing, a fine grinding sleeve, and a rolling bearing group. Although the overall volume is small and the weight is light, it can be repaired on site, but the repaired cylinder The inner diameter is single, and the repair of cylinders with different inner diameters requires the replacement of equipment workpieces
