steering wheel steering mechanism

Abstract

The invention discloses a steering wheel direction moving mechanism. Synchronization opposite-direction transmission is carried out by meshing of three gears, then synchronization identical-direction transmission is carried out in a transition mode, and steering is achieved. A transition gear is arranged in the middle, so that offset distance transmission from input (an opposite-moving small gear) to output (a rotating disc) is achieved, and the purpose of offset steering is achieved. The opposite-moving small gear, the transition gear and the rotating disc in the steering wheel direction moving mechanism are arranged on a direction component fixing plate. The opposite-moving small gear, the transition gear and a rotating disc gear are arranged on the same plane in a meshing-transmission mode for transmission, and three points at the mounting center are on the same straight line. The rotating disc is provided with a sector tooth face, and the two ends of the sector tooth face are provided with rotating angle limiting clamping positions for limiting the rotating angle quantity of the rotating disc respectively. The rotating disc is arranged on a main shaft of a front wheel fork frame component in a sleeved mode. Offset steering of a direction is achieved through meshing transmission of the three gears, and meshing transmission of the three gears is carried out from synchronization opposite-direction transmission to synchronization identical-direction transmission in a transition mode.

Description

technical field [0001] The invention relates to the field of a single-wheel steering system of an electric three-wheel sweeping vehicle, and more specifically, relates to a steering wheel steering mechanism. Background technique [0002] In the field of single-wheel steering system of electric three-wheel sweeper, the hand-held steering wheel offset device is operated on one side of the vehicle, so that the driving position is driven on the side of the vehicle body, which is convenient for better observation of roadside obstacles when driving the sweeper and sweeping effect status. [0003] At present, the existing electric three-wheel sweeping vehicles are driven by the two rear wheels, and the single wheel in the front is used for steering. They are all driven by a central hand-held steering wheel. The principle is that the hand-held steering wheel and the steering wheel are installed in the middle of the vehicle. It is connected to a pipeline rotating shaft by a hand-hel...

Problems solved by technology

[0004] The direction drive structure of the existing sweeping vehicle is to directly drive the large sprocket mounted on the upper end of the front wheel to drive the steering of the front tire by connecting the chain with the small sprocket on the small shaft. Therefore, the following disadvantages are arranged: 1. The steering wheel rotates Too much resistance affects safe operation; 2. The chain is easy to rust or break; 3. The steering angle of the front wheel is easily broken or deformed by the collision of the positioning pin; 4. The steering wheel is limited in the installation position of the vehicle
