A carbon-free trolley with gear shifting and variable pitch walking on an s-shaped path

Abstract

The invention discloses a carbon-free trolley with gear shifting and pitch-changing that travels on an S-shaped path, including a frame, a driving mechanism, a transmission mechanism, a steering mechanism and a gear-shifting pitch-changing mechanism arranged on the frame; it is different from the prior art Yes: the driving mechanism is connected to the transmission mechanism through a flexible cord, the transmission mechanism is fixed on the frame through the bearing seat, and connected to the steering mechanism through the reel shaft, the front wheel of the trolley is supported on one side, and there is an angle fine-tuning mechanism and The steering mechanism is rigidly connected. The carbon-free trolley with gear shifting and variable pitch for S-shaped path walking of the present invention can realize S-shaped path walking within the range of 700-1300 mm between two obstacles, and can realize large-variable-pitch adjustable walking. The design of the front wheel of the trolley of the present invention is relatively unique, and the detachability is good. The front wheels are equipped with axial positioning, which makes the running track of the trolley uniform and symmetrical with high precision.

Description

technical field [0001] The invention relates to a carbon-free trolley, in particular to a carbon-free trolley with gear shifting and variable distance traveling on an S-shaped path. Background technique [0002] The current carbon-free cars are all designed and manufactured based on the proposition of the National College Students Engineering Training Comprehensive Ability Competition. The proposition of the 4th competition requires: design a three-wheeled trolley, the energy driving it to walk and turn is obtained from the conversion of the given gravitational potential energy according to the principle of energy conversion. It is required that the energy required for the car to complete all actions during the walking process is converted from the given gravitational potential energy, and energy from any other source cannot be used. The trolley is required to have a steering control mechanism, and this steering control mechanism has an adjustable function to adapt to compe...

AI Technical Summary

Problems solved by technology

If you only rely on the rocker fine-tuning mechanism for adjustment, the adjustable distance is small

Moreover, the front wheel of this utility model trolley has poor detachability. After the front wheel is unloaded in the competition, the front wheel processed on site is replaced for a new race. The front wheel has no axial positioning, and the bearing is easy to loosen and yaw. The problem makes the running track of the trolley change, and the running accuracy is greatly reduced
