Hybrid transmission with high-speed self-disengaging function

Abstract

The invention discloses a hybrid transmission with a high-speed self-disengaging function, which comprises an input shaft for receiving power of an engine; a low-speed intermediate shaft; a high-speedintermediate shaft; a transmission mechanism arranged among the input shaft, the low-speed intermediate shaft and the high-speed intermediate shaft; an auxiliary motor directly connected with the engine; a coupling device arranged between the auxiliary motor and the transmission mechanism; a driving motor having a motor shaft arranged on the outer side of the input shaft in a sleeving mode and always meshed with a combination gear arranged on the high-speed intermediate shaft in a sleeving mode through a transmission gear, wherein the combination gear is provided with a self-disengaging device, and the self-disengaging device and a high-speed gear synchronizer arranged on the high-speed intermediate shaft are mutually exclusive. The self-disengaging device is adopted, it is guaranteed that the driving motor does not participate in driving any more after the vehicle speed exceeds the regulation limit vehicle speed, the engine is prevented from dragging the driving motor to idle throughinertia, and consumption of extra energy is avoided.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a hybrid transmission with a high-speed self-disengagement function. Background technique [0002] At present, among new energy vehicles in my country, hybrid vehicles are developing most rapidly. A hybrid vehicle is a vehicle that uses multiple energy sources, usually a conventional engine using liquid fuel and an electric motor using electrical energy to propel the vehicle. Hybrid vehicles can be driven in multiple modes. The hybrid transmission at this stage can generally perform operating modes such as engine independent drive, electric motor independent drive, and engine and electric motor simultaneous drive. [0003] However, the current hybrid transmission has the following defects: 1. The transmission system has a complex structure, takes up a large space, and is inconvenient to carry; 2. When the hybrid vehicle is in a high-speed state, the engine is in the high-eff...

Problems solved by technology

[0003] However, the current hybrid transmission has the following defects: 1. The transmission system has a complex structure, takes up a large space, and is inconvenient to carry; 2. When the hybrid vehicle is in a high-speed state, the engine is in the high-efficiency economic zone, but the drive motor will still be in the linked state. At this time, the engine needs to drive the motor rotor to idle or use the battery energy to drive the motor to offset its own inertia, which will lead to additional energy consumption
