Belt drive starter generator

Abstract

The invention relates to a belt transmission type starting and power generation integrated machine. The belt transmission type starting and power generation integrated machine comprises a belt pulley, a driving end cover assembly, a stator assembly, a rotor assembly and a carbon brush end cover assembly and is characterized in that a bearing chamber is arranged at a position, corresponding to a rotor shaft, at the middle of a carbon brush end cover, a bearing sensor is arranged in the bearing chamber, the end part of a carbon brush in a carbon brush rack props against the circumferential surface of a current collection ring of a rotor shaft, a junction box is further arranged outside the carbon brush end cover, a wiring seat is fixedly arranged in the junction box and is used for connecting three phase cables, cable heads of the three phase cables are separately and fixedly provided with connection sheets, the connection sheets separately pass through a socket of the junction box and enter to the junction box to be fixedly connected with the wiring seat, a sealing cover is fixedly arranged at the top of the junction box, a temperature sensor is arranged at the end part of a stator iron core, and a signal wire connector of the temperature sensor is fixed on the carbon brush rack. The belt transmission type starting and power generation integrated machine is compact in structure and has the advantages of a rapid starting function, low starting noise, automatic switching between starting and power generation and high power generation efficiency, and also has functions of assisted electric power for an engine and vehicle braking energy recycle.

Description

technical field [0001] The invention relates to the field of automobile generators and starters, in particular to a belt-driven starter-generator integrated machine that can replace traditional automobile generators and starters, and is suitable for automobile start-stop systems. Background technique [0002] Hybrid power is a technology applied to a new generation of energy-saving vehicles with low fuel consumption and low pollution. It is an effective combination of traditional internal combustion engine vehicles and electric vehicles. It not only inherits the advantages of low emissions from electric vehicles, but also develops the advantages of high specific energy and specific power of petroleum fuels, and significantly improves the emissions and fuel economy of traditional internal combustion engine vehicles. Micro-hybrid and weak-hybrid technologies mainly include start-stop system and belt-driven starter / generator technology (BSG for short), through which the engine ...

AI Technical Summary

Problems solved by technology

With the gradual increase of the electric load of the whole vehicle, the existing belt-driven starter / generator integrated machine has the following problems: 1. The connection method of the three-phase cable is easy to cause fatigue fracture in the use of the whole vehicle; 2. The terminal is damaged by salt spray Corrosion, resulting in poor voltage resistance; 3. The position sensor usually uses an expensive resolver type position sensor, which makes the cost of the whole machine too high
