Planetary gear power-distributing-type steering mechanism

Abstract

The invention discloses a planetary gear power-distributing-type steering mechanism which comprises a box. A middle power transmitting part, a steering control part, a steering planetary transmission part, a left external driving gear and a right external driving gear are installed on the box. The box is connected with a gearbox, a power output shaft of the gearbox is connected with the steering planetary transmission part, the steering planetary transmission part is respectively connected with the left external driving gear and the right external driving gear, and the steering control part is connected with the steering planetary transmission part through the middle power transmitting part to achieve steering control. According to the planetary gear power-distributing-type steering mechanism, steering power is input from gear rings of a planetary gear transmission mechanism in a distributed mode to a traveling transmission mechanism through steering bevel gears to achieve steering, power failures do not exist during steering, and the transmission efficiency is high; indirect control is adopted for steering control, and on the premise that the steering control characteristic is guaranteed, the structure of the steering planetary transmission part is effectively simplified; the planetary gear power-distributing-type steering mechanism is easy and convenient to operate, driving is easily carried out, and convenience is brought to achieving high-accuracy steering wheel steering of a caterpillar tractor.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery steering, in particular to a planetary gear power split steering mechanism. Background technique [0002] At present, crawler tractor vehicles usually adopt a steering scheme in which the steering rod operates the jaw clutch and multi-disc brakes. The realization process is: when the crawler tractor turns to the left, the driver operates the left steering rod to make the left jaw The clutch is disengaged and the output shaft on the left side is braked. Since the transmission power on the left side of the crawler tractor is interrupted and braked to stop the rotation, at this time, driven by the power on the right side of the tractor, the implement turns to the left side; the same operation can be realized Right-hand steering, however, this kind of steering mechanism is realized by separating and combining jaw clutches and brakes, which easily generates axial force between mechanical...

Since the transmission power on the left side of the crawler tractor is interrupted and braked to stop the rotation, at this time, driven by the power on the right side of the tractor, the implement turns to the left side; the same operation can be realized Right-hand steering, however, this kind of steering mechanism is realized by separating and combining jaw clutches and brakes, which easily generates axial force between mechanical equipment, low steering precision, and poor steering controllability, and due to power interruption during the steering process, This leads to low transmission efficiency and increases energy consumption
