Problems solved by technology

If the engine is already working in the high-efficiency zone and can drive the vehicle well, the two motors still continue to work at this time, which will inevitably cause the system efficiency of the vehicle to be low in this situation.
And if there is a motor failure in the system, the vehicle will not be able to drive

Abstract

The invention belongs to a hybrid driving device for a vehicle, and in particular discloses a power-split hybrid driving device with blocking function. A planetary gear comprises a gear ring, a planet carrier, planet gears and a sun gear; the gear ring is meshed with a plurality of planet gears positioned in the gear ring; the plurality of planet gears are meshed with the same sun gear; the planet carrier is fixedly connected with the plurality of planet gears; the outer periphery of the gear ring is fixedly connected with an engine; a first motor is fixedly connected with the sun gear; one end of a second motor is fixedly connected with the planet carrier, while the other end is connected with a mechanical gearbox; and a lockup clutch is arranged between any two parts of the gear ring, the planet carrier and the sun gear. The device ensures that a power-driven system of the vehicle has multiple working modes and keeps high-efficiency operation, and simultaneously ensures that the vehicle still can normally run under the condition of the failure of the motor or a frequency convertor.

Description

technical field [0001] The invention belongs to a vehicle hybrid drive device, in particular to a power split type hybrid drive device with a locking function suitable for crawler vehicles or heavy wheeled vehicles. Background technique [0002] In the current power-split hybrid drive system, the engine and two motors are respectively directly connected with three members of a planetary row. The planetary row includes the ring gear, the planet carrier, the planetary gear and the sun gear, etc. Such as figure 1 As shown, the engine 1 is fixedly connected to the ring gear 3, the first motor 6 is fixedly connected to the sun gear 5, the second motor 7 is fixedly connected to the planet carrier 4, and the ring gear 3 meshes with a plurality of planetary gears 9 inside it. Several planetary gears 9 are in gear mesh with the same sun gear 5, and the planetary carrier 4 fixedly connects several planetary gears 9 together. The outer edge of the ring gear 3 is fixedly connected to...
