Abstract

The invention discloses a dedicated hybrid transmission, The dedicated hybrid transmission comprises an engine, a generator, a drive motor, input assemblies, output assemblies and an output drive gear, wherein the input assemblies comprise a first gear input shaft, a driving shaft, a second gear input shaft, a driven shaft, a driving gear, a first driving gear, a second driving gear, a third driving gear and a first driven gear, wherein the second driving gear and the third driving gear are arranged on the second gear input shaft, the output assemblies comprise an output shaft, a second drivengear, a third driven gear and a power engaging device selectively combined with the second driven gear or combined with the third driven gear, the second driven gear is meshed with the second drivinggear, the third driven gear is meshed with the third driving gear, and the output driving gear is arranged on the output shaft. According to the dedicated hybrid transmission, through the combinationof a clutch and an electromotor, the generator and the engine, two driving gears and multiple operating modes can be realized, so that the power performance and economical efficiency of a whole vehicle can be improved to the maximum extent.

Description

Technical field [0001] The invention belongs to the technical field of gearboxes. Specifically, the invention relates to a hybrid gearbox. Background technique [0002] The hybrid gearbox integrates the electric motor, generator and engine, and utilizes the characteristics of large starting torque, wide speed range, and high overall efficiency of the electric motor to improve the acceleration and climbing performance of the vehicle, while reducing the energy consumption of the vehicle. The generator allows the engine to run at a stable and highest efficiency operating point to provide high-voltage power to the motor, thereby further reducing the fuel consumption of the vehicle. [0003] Existing hybrid gearboxes have only one gear, leading to the following limitations: [0004] 1. The motor needs a large torque to meet the low-speed power performance, and the speed demand is high to meet the maximum speed requirement; [0005] 2. The high input speed results in high technical require...
