Problems solved by technology

[0004] my country's tracked vehicles are mostly driven by fixed-axis mechanical transmission and single power flow transmission. They adopt the form of brake steering and drive fans through mechanical transmission, which affects the acceleration performance of the vehicle. It is impossible to realize the stepless change of the transition radius of each gear, which is difficult to achieve Stepless adjustment of fan speed

Abstract

The invention belongs to the technical field of crawler vehicle transmission, and specifically relates to a hydraulic-hydraulic-mechanical composite multi-power flow transmission device, which includes: five planetary rows, six hydraulic components, one axial plunger conjoined pump motor, six screw Bevel gears, thirty-two spur gears, four brakes and three clutches; the present invention realizes hydraulic pressure, hydraulic compound steering, two stepless speed regulation outputs, and realizes six forward gears and three reverse gears, each All gears have the function of stepless adjustment of the output speed and torque, which realizes the stepless adjustment of the speed and torque of the auxiliary power output. The invention is suitable for longitudinally arranged engines, rear-mounted rear-drive powertrains, and large-tonnage crawler vehicles.

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...
