Robot vehicle body suspension system

Abstract

The invention is a robot vehicle body suspension system, relating to the movable robot mechanism design field. The robot vehicle body suspension system which consists of a drive component, a frame base board component and a vibration damper plate component adopts a layering, two stage shock absorption mechanism; the first layer of the shock absorption mechanism is provided with a left electric motor, a right electric motor, a left driving wheel and a right driving wheel; the second layer is provided with a front and a back follow up pulleys; the first layer is in elastic connection with the second layer by a compression spring set; the front and the back follow up pulleys connected with each other by a tension spring are capable of wholly rotating around a front and a back rotation axis pair; the left and right driving wheel are respectively driven by separate electric motors; the sleeve bolt set under the springs of the frame base board component are all divided into four groups and each group has 4 bolts; the sleeve bolt set above the springs of the vibration damper plate component are all divided into four groups and each group has 4 bolts. Thereby the invention has the advantages of having perfect shock absorbing capability of the vehicle body and prolonging service life of elements and components, along with a simple structure and reliability.

Description

Technical field [0001] The invention is a robot vehicle body suspension system, which relates to the field of mobile robot mechanism design. Background technique [0002] A wheeled mobile robot with a two-wheel differential drive mechanism is generally composed of two drive wheels and a follower wheel. The disadvantages of this mechanism are poor adaptability to the ground and poor car body symmetry. If the mechanism of left and right driving wheels and front and rear follow-up wheels is adopted, the performance will be significantly improved, but the problem is the height positioning of the four wheels. If the heights are inconsistent, the wheels will hang in the air when running on a horizontal plane. The car body is unstable. If the height is the same, there will be wheels hanging in the air when running on uneven roads, causing loss of control and algorithm failure. Automobiles often use suspension systems, which are used to transmit various forces and moments on the wheels t...
