Integrated Hybrid

Abstract

The invention relates to integrated oil-electric hybrid power which is used in a motor vehicle and has the functions of over-speed unloading and speed-limiting braking. A coil stator of a motor is fixed on a machine body on the side of an output shaft of an engine, an inner circle of a bearing sleeve of a cup-type shaft is in close fit to the outer ring of a unilateral bearing, an inner circle of the unilateral bearing is in close fit with the output shaft of the engine, and an outer rotor of the motor is fixed on the end face of the bearing sleeve on the middle section of the cup-type shaft. After the motor vehicle is accelerated or runs on a gentle slope and the rotation speed of the motor vehicle is higher than the rotation speed of the engine, the unilateral bearing is in the separating state, the motor does not output power, and the engine is stopped to enable the motor vehicle to run in a sliding mode. When the motor vehicle runs on an abrupt slope or a long slope, the engine is stopped, the motor is driven by loads to rotate to be in the electric generating state, the current of a coil is rectified by a controller to be sent to a dissipation resistor to generate heat, the energy consumption brake force generated by the motor enables the motor vehicle to be decelerated, the energy consumption brake current can be adjusted by the controller according to the difference of the traveling vehicle speed and the set vehicle speed, the speed of the motor vehicle is limited to enable the motor vehicle to be stopped to run in a sliding mode, the oil consumption is reduced, and the service life of the engine is prolonged.

Description

technical field [0001] The invention relates to an oil-electric hybrid power used in a motor vehicle with the functions of overspeed unloading and speed limit braking. Background technique [0002] When the motor vehicle is accelerating, refueling or going down a gentle slope, the inertial kinetic energy of the motor vehicle is greater than the output kinetic energy of the engine. At this time, the engine becomes a "damping mechanism" that consumes energy, so some experienced drivers habitually hang It can save energy and reduce fuel consumption, and prolong the service life of the engine. Don’t underestimate this unloading and sliding technology. If it is used well, it can save 20% of fuel. Although the fuel saving rate is very impressive, due to Mastering the technology of unloading and sliding requires certain driving experience and is labor-intensive, so few people use it in practical applications.

[0002] When the motor vehicle is accelerating, refueling or descending a gentle slope, the inertial kinetic energy of the motor vehicle is greater than the output kinetic energy of the engine. At this time, the engine becomes a "damping mechanism" that consumes energy, so some experienced drivers habitually hang It can save energy and reduce fuel consumption, and prolong the service life of the engine. Don’t underestimate this unloading and sliding technology. If it is used well, it can save 20% of fuel. Although the fuel saving rate is very impressive, due to Mastering unloading and sliding technology requires certain driving experience and high labor intensity, so few people use it in practical applications

In addition, when the motor vehicle goes down a steep or long slope, in order to exert the "damping" deceleration function of the engine and prevent the mechanical brake from overheating and the brake pad from wearing out too quickly, it is not allowed to drive in neutral gear, which increases the wear and tear of the engine and shortens the service life
