Abstract

A multi-gear hydrodynamic transmission applicable to various working conditions mainly comprises a hydraulic torque converter and a multi-gear power shift gearbox with an integral box. An output shaft of the hydraulic torque converter is connected together with an input shaft of the gearbox, and an input gear is fixedly connected onto the input shaft. A KR driving gear engaged with the input gear is fixedly connected onto a KR shaft, an R driving gear is hollowly sleeved on the KR shaft through a rolling bearing, and a KR multi-disc wet friction clutch is arranged on the KR shaft. A KV driving gear engaged with the input gear is fixedly connected onto a KV shaft, a V driving gear is hollowly sleeved on the KV shaft through a rolling bearing, and a KV multi-disc wet friction clutch is arranged on the KV shaft. A K1 driving gear is fixedly connected onto a K1/3 shaft, a K3 driving gear is hollowly sleeved on the K1/3 shaft through a rolling bearing, and a K1/3 multi-disc wet friction clutch is arranged on the K1/3. The multi-gear hydrodynamic transmission is totally provided with six multi-disc wet friction clutches and two multi-disc wet friction brakes, different gears of the gearbox are obtained by means of different combinations of the wet friction clutches and the wet friction brakes, and the performance requirement of a finished vehicle under different working conditions is met by selecting hydraulic torque converters with different performances.

Description

technical field [0001] The invention relates to a hydraulically controlled, multi-gear hydraulic transmission composed of a hydraulic torque converter and an integral box-type multi-gear power shift gearbox, which can meet the needs of locomotive walking, working, towing, etc. The utility model is used in various working conditions; it is a multi-gear hydraulic transmission suitable for railway engineering and engineering machinery road vehicles, and belongs to the technical field of power transmission mechanisms. Background technique [0002] Among the existing hydraulic transmissions of the same type, it is generally a power shift transmission, and its output end is connected by gear sleeves to realize the power output of the locomotive. Currently, the same type of multi-gear hydraulic transmissions commonly used The operation is not flexible enough, the structure is easily damaged, it is difficult to use when switching between different working conditions, and the use of ...
