Method for integrating transmission system of hybrid vehicle and device

Abstract

Disclosed are a method for integrating a single-axle parallel-connection hybrid system and a device. A speed changer is fixedly connected with a motor in a spigot positioning manner, the motor is fixedly connected with a flywheel shell of an engine in a spigot positioning manner, and an input shaft of the speed changer is connected with an output shaft of the motor via splines; and a blind hole inner spline is arranged at the end of the input shaft of the speed changer, an outer spline which matches with the inner spline at the end of the input shaft of the speed changer is arranged at the end of the output shaft of the motor, the outer spline of the output shaft of the motor is directly inserted in the blind hole inner spline at the end of the input shaft of the speed changer, and accordingly the input shaft of the speed changer is connected with the output shaft of the motor via the splines. In addition, a motor shell and a clutch shell share the same side wall, an original side wall of the clutch shell is omitted, and a support of a clutch operating lever moves on the side wall of the motor shell. The splines are involute splines, the involute splines are modified, and axial pressure and axial force of the splines due to errors of coaxiality are weakened.

Description

technical field [0001] The invention relates to a composition method and device of a transmission system of a hybrid electric vehicle, in particular to an integration method and device of a motor and a transmission, and a motor and a clutch housing. The method can reduce the length of the transmission chain of the hybrid power system, making the hybrid The power transmission system has become a general platform for transmission systems that can be applied to 9-meter, 10-meter and 12-meter hybrid buses. Background technique [0002] Hybrid vehicles have the characteristics of high fuel-saving rate, low pollution, and environmental protection, and have been developed rapidly in recent years. Hybrid vehicles are generally mixed in parallel, and hybrid parallel hybrid vehicles are divided into two power coupling forms: single-shaft parallel connection and angular transmission parallel connection. [0003] Compared with the angular transmission hybrid system, the transmission sy...

Problems solved by technology

[0009] The purpose of the present invention is to propose a new single-axis parallel hybrid system integration method for the problem that the existing single-axis parallel hybrid power system is difficult to apply to 9-meter and 10-meter vehicles due to its long longitudinal length and a device, the method and device can be used to reduce its longitudinal length, so that the single-axis parallel hybrid system can be well applied to vehicles of 9 meters and 10 meters
