AI Technical Summary

Technical Problem

The diversified space distance between the engine and the torque converter leads to the need for higher strength materials for flexible discs, which increases cost and difficulty in processing.

Method used

By thickening the composite pad, the space distance between the engine and the torque converter is supplemented. The specific implementation method is to pass the shaft end of the composite pad through the through hole of the flexible disk and plug it into the gasket. The gasket is assembled with the flexible disk by self-riveting, and the thickness of the composite pad is adjustable.

Benefits of technology

Without significantly changing the flexible disc pressure depth, by thickening the composite pad, the space distance between the engine and the torque converter is effectively supplemented, reducing material strength requirements, and reducing cost and processing difficulty.

Description

Technical Field

[0001] The utility model relates to the field of automobile flexible flywheel design, in particular to an automobile flexible flywheel assembly. Background Art

[0002] The flexible flywheel assembly is installed at the end of the engine to provide power input for the gearbox. This flywheel is used with an automatic gearbox. The engine starter gear ring is near the crankshaft end, and a hydraulic torque converter is connected to the rear end. The hydraulic torque converter is a non-rigid coupling that uses liquid as the working medium.

[0003] In recent years, automobile competition has become increasingly fierce, and car models have become more diverse. Different engines or torque converters are used in combination, but the engine layout and the torque converter layout are inconvenient to change, which results in a variety of spatial positions between the engine and the torque converter. Too far a distance will result in the need to use higher strength materials for the flexible disk. As the cost rises, the processing difficulty also rises sharply. The utility model provides an automobile flexible flywheel assembly to solve the above problems. Under the premise of not significantly changing the pressing depth of the flexible disk, the spatial distance between the engine and the torque converter is supplemented by thickening the composite pad. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0005] An automobile flexible flywheel assembly comprises a gear ring, a flexible disc, a gasket and a composite gasket;

[0006] The outer sleeve of the flexible disk is connected to the gear ring, and a through hole is provided at the axis of the flexible disk. The axial end of the composite pad passes through the through hole and is sleeved in the gasket. The gasket is assembled with the flexible disk by self-riveting.

[0007] The thickness of the composite pad is adjustable.

[0008] Preferably, the shaft end of the composite pad is connected to the flexible disk by laser welding.

[0009] Preferably, the gear ring and the flexible disk are connected by welding.

[0010] Preferably, the composite gasket includes a first gasket and a universal gasket, the axial end of the first gasket passes through the through hole and is sleeved in the gasket, the outer end face of the first gasket is provided with three structurally symmetrical arc grooves, one end face of the universal gasket is provided with three structurally symmetrical arc plug-ins that are plugged into the arc grooves, and the other end face is provided with three structurally symmetrical arc grooves, and the arc grooves of the universal gasket are connected to the arc grooves of the first gasket by riveting.

[0011] The beneficial effects of the utility model are as follows: the utility model has a simple structure and low manufacturing cost. The thickness of the composite pad can be optimized according to the spatial distance between the engine and the torque converter. The first pad can be used alone. When the thickness needs to be increased, the universal pad can be inserted into the first pad and then riveted firmly for use. Under the premise of not significantly changing the pressing depth of the flexible disc, the spatial distance between the engine and the torque converter can be supplemented by thickening the composite pad.
