Embodiment Construction

[0014] combine figure 1 , 2 , 3, 4, 5 to specifically illustrate the present invention, the fine-tuning crank is fixed on the bevel gear driven wheel, the fine-tuning nut connects the fine-tuning crank and the fine-tuning rod, and the fine-tuning rod is connected with the cross bar through the fine-tuning nut, Described cross bar is fixed on the front wheel support, and described fine-tuning nut, fine-tuning long bar, turning nut and cross bar constitute crank connecting rod variable distance fine-tuning system.

[0015] When in use, since the potential energy mass block 16 is connected with the drive shaft 2 through the wire rope, the wire rope bypasses the fixed pulley 12, the potential energy mass block 16 gradually rises until the dropable height is 400±2mm, the power preparation of the trolley is completed, and the carbon-free trolley Put it in front of the starting line so that the front wheels of the trolley are flush with the starting line, adjust the length of the cr...

Abstract

The invention relates to a carbon-free trolley steering gear, a fine adjustment long rod is connected with a cross rod through a fine adjustment nut, the cross rod is fixed on a front wheel support, the fine adjustment nut, the fine adjustment long rod, a rotational nut and the cross rod constitute a crank connecting link displacement fine adjustment system, the carbon-free trolley steering gear adopts a crank connecting link mechanism so as to realize trolley steering fine adjustment, by changing the relative positions of the fine adjustment nut and a fine adjustment crank rotation center shaft, the position of the fine adjustment nut, which is on the fine adjustment long rod, realizes the obstacle crossing requirement for different intervals within 700 millimeters to 1300 millimeters, as the crank connecting link mechanism does not have a sliding pair of a sine mechanism, the energy consumption caused by friction is reduced greatly, simultaneously, the precision prescribed is relatively lowered, and thus batch production can be realized.

Description

technical field [0001] The invention relates to a steering device, in particular to a carbon-free trolley steering device. Background technique [0002] The carbon-free trolley is designed and manufactured based on the background of the National Undergraduate Engineering Training Comprehensive Ability Competition. It is a product based on the engineering training of mechanical students. The requirement for the carbon-free trolley in the National Undergraduate Engineering Training Comprehensive Ability Competition is to design a three-wheeled trolley , the car is required to have a steering control mechanism, and this steering control mechanism has an adjustable function to adapt to the competition field with obstacles at different distances. Therefore, the steering mechanism is the key to the design and manufacture of carbon-free cars. Sinusoidal mechanisms are often used on trolleys, which cannot be mass-produced and applied, and have no practical significance for promotion...
