Embodiment 1

[0074] Such as figure 1 As shown, the steering transmission system is arranged between two wheel assemblies 1 . The steering transmission system includes a bogie, a knuckle arm tie rod 3 and a steering knuckle arm 2. A vertical arm 10 is fixedly connected to the bogie. One end of the steering knuckle arm 2 is hinged; the number of steering knuckle arms 2 is two, and one end of each steering knuckle arm 2 away from the corresponding knuckle arm tie rod 3 is fixedly connected with the steering knuckle of the corresponding wheel assembly 1, so as to drive the knuckle arm tie rod 3 when the bogie rotates Drive the steering knuckle arm 2 to move, and then realize the steering of the wheel assembly 1.

[0075] In this embodiment, the bogie includes a driving arm 6 and a driven arm 9, the driving arm 6 is rotatably mounted on the first articulated shaft 5, and the driven articulated arm 9 is rotatably mounted on the second articulated shaft 8, wherein, The first articulated shaft 5...

Embodiment 2

[0082] Such as figure 2 As shown, the difference from Embodiment 1 is that the vertical arm 10 is not arranged on the driving arm 6 and the driven arm 9, but is arranged on two steering knuckle arms 2, and one end of the knuckle arm pull rod 3 is connected to the corresponding The rotating arm is hinged, and the other end is slidably fitted on the vertical arm 10 of the steering knuckle arm 2 through a sliding sleeve 12 .

Embodiment 3

[0084] Such as image 3 As shown, the difference with Embodiment 1 is that the vertical arm 10 is not arranged on the driving arm 6 and the driven arm 9, but is arranged on one end of the two knuckle arm pull rods 3, and the steering knuckle arm 2 passes through the sliding The sleeve 12 is slidingly assembled on the vertical arm 10 of the joint arm pull rod 3, and the other end of the joint arm pull rod 3 is hinged with the corresponding rotating arm.

Abstract

The invention relates to a steering transmission system and a special vehicle. The steering transmission system comprises a bogie, two steering knuckle arms and knuckle arm pull rods, wherein the bogie is rotatingly assembled on a frame, the bogie is provided with a driving connection part, and the driving connection part is used for being in transmission connection with a steering gear, so as toachieve the rotation of the bogie on the frame; the two steering knuckle arms are arranged on the two sides, in the width direction of the frame, of the bogie correspondingly; the knuckle arm pull rodis arranged between the bogie and the corresponding steering knuckle arm; one end of the knuckle arm pull rod is hinged to the steering knuckle arm, the knuckle arm pull rod is in transmission connection with the bogie through the vertical arm, one of the knuckle arm pull rod and the bogie is in guide fit with the vertical arm in the axial direction of the vertical arm, and the other one is in limiting fit with the vertical arm in the axial direction of the vertical arm. The relative movement stroke of the knuckle arm pull rod or the bogie and the vertical arm in the axial direction of the vertical arm is not smaller than the retracting and releasing movement stroke of a wheel assembly on the frame.

Description

technical field [0001] The invention relates to a steering transmission system and a special vehicle. Background technique [0002] Some special vehicles have working conditions on land and water. When driving on land, special vehicles rely on the friction between the wheels and the ground to advance, but when sailing in water, the wheels need to be retracted to reduce resistance. [0003] The Chinese patent with the authorized notification number CN201415706Y discloses a steering system for air independent suspension. The steering system includes a steering gear and a steering linkage. The left and right middle rocker arms, middle tie rods and straight steering rods are composed; the left and right middle rocker arms are respectively connected to the frame through pin shafts, the two ends of the middle tie rods are hinged in the middle of the left and right middle rocker arms, and the left and right tie rods are two The ends of the steering knuckle arms are respectively co...
