Abstract

The invention belongs to the technical field of crawler transmission and particularly relates to a hydro-mechanical compound multi-power flow transmission device. The hydro-mechanical compound multi-power flow transmission device comprises five planetary lines, six hydraulic units, an axial plunger pump motor, six spiral bevel gears, thirty two straight gears, four brakes and three clutches. The hydro-mechanical compound multi-power flow transmission device achieves hydro-mechanical compound steering, double stepless speed control output, six forward gears and three reverse gears, wherein every gear achieves a function of stepless rotating speed and torque adjusted output to achieve stepless rotating speed and torque adjustment for assisting power output. The hydro-mechanical compound multi-power flow transmission device is applicable to large-tonnage crawlers with longitudinal arrangement of an engine and rear arrangement and driving a power assembly.

Description

technical field [0001] The invention belongs to the technical field of crawler vehicle transmission, and in particular relates to a hydraulic-hydraulic-mechanical composite multi-power flow transmission device. Background technique [0002] As a tracked vehicle driving transmission device, it is divided into two types according to the power transmission form. The first type is mechanical transmission. Generally, the gearbox with a fixed transmission ratio transmits the engine power to the drive wheel of the tracked vehicle according to multiple fixed transmission ratios. Drive the track to rotate. The second type is a compound transmission integrated with hydraulic, hydraulic, mechanical and other power transmission forms. Generally, the hydraulic coupling, hydraulic torque converter, hydraulic reducer and gear transmission are integrated to convert the power of the engine and transmit it to The drive wheel of the tracked vehicle drives the track to rotate, which realizes t...
