Abstract

A dual-power flow diversion mechanism of a hydromechanical transmission tracked vehicle comprises an engine, a torque converter, a transmission, a hydraulic control system, a housing (1), a bevel gear(2), a transmission input bevel gear (2'), a bevel gear (3), a steering hydraulic motor bevel gear (3'), a left track (4), a right track (5), a sun gear (6), a planet carrier (7), a planetary gear (8), a planetary gear (9), a planetary gear (10), a sun gear (11), a planet carrier (13) and a ring gear (14). Compared with the traditional steering clutch and brake steering mechanism, the steering mechanism has better steering performance, can realize in-situ steering and is flexible in steering. The steering speed can be reduced and the torque can be increased, and the operation is reliable. Thesteering operation is convenient and the steering wheel can be used to control the motor speed, and the steering characteristics of different steering radii can be realized. The steering mechanism isapplied to the hydro-mechanical transmission tracked vehicle, and its steering performance is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of hydraulic mechanical transmission crawler vehicles, in particular to a dual power flow steering mechanism of hydraulic mechanical transmission crawler vehicles. Background technique [0002] Tracked vehicles are mainly used in engineering machinery and military vehicles, such as bulldozers, excavators, and tracked armored vehicles. Therefore, high demands are placed on the steering mechanism of tracked vehicles. [0003] Generally, the steering mechanism of tracked vehicles can be divided into two categories. The first type is a differential gear mechanism similar to a wheeled vehicle. The steering of the vehicle is controlled by clutches and brakes in conjunction with the torque of the track drive wheels on both sides. This is the case for most tracked vehicle steering mechanisms at present; the second type is in the The track drive wheels on both sides are equipped with independent steering mechanisms...
