Power generation method of power generation box with gear speed increase

Abstract

The invention discloses a power generation cabinet with a gear increaser and a power generation method thereof. The power generation cabinet is used combining with an engine, a generator and a driving motor. An input terminal of a power generation cabinet body is connected with an engine flywheel. One output terminal of the power generation cabinet body is connected with the generator and the other output terminal is connected with the input terminal of the driving motor. The output terminal of the driving motor is connected with a transmission shaft. The power generation cabinet comprises: a first gear, a main clutch, a transition gear, a second gear and a generator clutch. The invention has the following advantages that: the main clutch is of a normally open type, which increases a utilization rate of the driving motor and a fuel saving ratio substantially; a thrust of the main clutch is not applied on other components, which increases a service life of the engine; the main clutch and the generator clutch can be pneumatically controlled or hydraulically controlled so that applicability is wide; the gear is used to carry out generator transmission torque so that reliability is good, a generator input speed can be increased and generator cost can be reduced.

Description

technical field [0001] The invention relates to a power generation device of a hybrid electric vehicle, in particular to a power generation method of a power generation box with a gear increasing speed. Background technique [0002] At present, the main clutch of a hybrid vehicle is mainly a dry friction clutch. Its working principle is: use a diaphragm spring (or coil spring, disc spring) and other compression elements to act on the clutch pressure plate to tighten the clutch driven plate assembly. It is pressed between the flywheel and the pressure plate to generate a certain friction torque, so as to transmit the power of the engine to the transmission system, and then drive the vehicle forward or backward; when the clutch is disconnected, use the control system to drive the release bearing, and push (pull) the clutch The release lever (or diaphragm spring release finger) uses the principle of leverage and (or) the elastic restoring force of the transmission plate to ...

AI Technical Summary

Problems solved by technology

However, the current main clutch still uses a dry friction clutch, which greatly reduces the utilization rate of the drive motor

For example, when the drive motor is driven, the release bearing is always pressed against the clutch driven disc, which makes the release bearing work for a long time, so that the service life of the release bearing is greatly reduced

At the same time, the engine is also subjected to long-term axial pressure, and the service life of the engine is also affected, which increases the maintenance cost of the hybrid vehicle

[0004] In addition, the existing power generation system of hybrid electric vehicles adopts belt drive, which has low efficiency and high failure rate, and the gap of electromagnetic clutch often needs to be adjusted, and the maintenance cycle time is short
