Novel vehicle weak-medium degree hybrid power synthetic system

Abstract

The invention relates to a novel vehicle weak-medium degree hybrid power synthetic system, which is adopts a motor, a planetary gear set and a high-speed flywheel assembled together, is suitable to be used as starting acceleration assistance and recover braking energy for various automobiles, tractors, hybrid power vehicles, all terrain vehicles and electric vehicles, and is particularly suitable to be used by city buses. The novel vehicle weak-medium degree hybrid power synthetic system is characterized in that: a planet carrier (1) of the planetary gear set and a wheel are connected or in parallel connection with a vehicle drive system; a sun wheel (2) is coaxially connected with a driving part of a clutch (8); a driven part of the clutch (8) is connected with the flywheel (6) which is connected with the motor (9); a planet wheel (3) is arranged on the planet carrier (1) and is meshed with an inner gear ring (4) of the sun wheel (8); the periphery of the inner gear ring (4) is provided with a brake strap (5); the planet carrier (1) can be connected with a gear (7); and the gear (7) can be connected with a wheel or the drive system.

Description

technical field [0001] The present invention relates to a new type of vehicle-used weak-moderate hybrid power synthesis system, which uses a combination of a high-speed flywheel (not an ultra-high-speed flywheel for new energy vehicles), a planetary row and a motor to realize start-up and acceleration assist, and recover braking energy It is suitable for all kinds of automobiles, tractors, motorcycles, ATVs, hybrid electric vehicles and electric vehicles for braking energy recovery and secondary traction, especially for urban buses and cars.

Problems solved by technology

[0002] Nowadays, as the energy storage device of new energy vehicles, the flywheel is mainly connected directly with the motor, and its manufacturing cost and difficulty are relatively large; the current braking energy recovery of automobiles mainly adopts the working condition of converting the motor into a generator, and converting the braking energy In order to store electric energy in the battery, the braking energy absorption of this scheme is limited by the power of the motor itself and the charging current of the battery; after that, there is a scheme for the battery and supercapacitor to absorb the output energy of the generator, because the motor itself Due to the large power and cost, it has not yet reached the point of market application; as for using the hydraulic system to absorb the braking energy of the car, the system itself is large in size and high in cost; for pure electric vehicles, due to the limited motor torque, its starting performance is not as good as internal combustion engine vehicle

At present, there is no device or system for recovering the braking energy of internal combustion engine-driven vehicles in the market, which can achieve good results, and has the characteristics of low cost and small size. At the same time, there is currently no suitable device that can effectively improve the shortcomings of slow start of electric vehicles.
