Problems solved by technology

[0003] A DHT transmission known in the prior art has an additional gear set on the transmission output shaft, which is used as a reverse gear in the pure internal combustion engine drive mode, which makes the layout of the vehicle complex, increases the cost, and is very difficult for the system The impact resistance and efficiency are unfavorable
[0004] And another kind of known DHT speed changer has a coupling tooth clutch and three synchronizers, the control of coupling tooth clutch is comparatively complicated, can cause complex structure and high cost
In addition, this transmission uses a one-way clutch for lower component costs, but results in the addition of a separate starter for the internal combustion engine, which in turn increases overall cost

Abstract

The invention discloses a hybrid power transmission used for a hybrid power system and a vehicle. The hybrid power transmission comprises a transmission input shaft connected with an internal combustion machine through a clutch, a transmission output shaft, a first gear, a third gear, a fifth gear, a second gear, a fourth gear, a sixth gear, a first synchronizer arranged on the transmission inputshaft in a torsion resistance mode and a second synchronizer arranged on the transmission output shaft in a torsion resistance mode, wherein the first gear, the third gear and the fifth gear are arranged on the transmission input shaft in an empty sleeving mode, and the second gear, the fourth gear and the sixth gear are arranged on the transmission output shaft in an empty sleeving mode. The first gear and the second gear are engaged, the third gear and the fourth gear are engaged, and the fifth gear and the sixth gear are engaged. The first synchronizer can be connected with the first gear or the third gear in a torsion resistance mode, the second synchronizer can be connected with the fourth gear or the sixth gear in a torsion resistance mode, the third gear and the fifth gear are connected in a torsion resistance mode, and the fourth gear and the sixth gear are connected in a torsion resistance mode.

Description

technical field [0001] The invention relates to a hybrid transmission for a hybrid system. Furthermore, the invention relates to a vehicle with a corresponding hybrid system. Background technique [0002] A hybrid transmission (DHT) is a special transmission for hybrid drive systems that offers many advantages: DHT transmissions are more compact and efficient, the combustion engine can run more precisely in the power range with the support of the electric drive , so as to reduce energy consumption; in addition, the electric drive can provide additional power to increase power. [0003] A DHT transmission known in the prior art has an additional gear set on the transmission output shaft, which is used as a reverse gear in the pure internal combustion engine drive mode, which makes the layout of the vehicle complex, increases the cost, and is very difficult for the system The impact resistance and efficiency are disadvantageous. [0004] While another known DHT transmission...
