Inverse tricycle composite multi-connecting rod damping mechanism

Abstract

The invention relates to an inverse tricycle composite multi-connecting rod damping mechanism, comprising a connecting rack, which is characterized in that the connecting rack is hinged to an upper arm, a left lower arm, a right upper arm, and a right lower arm, wherein a left connecting rod assembly is connected between the free end of the left upper arm and the left lower arm; a right connectingrod assembly is connected between the free end of the right upper arm and the right lower arm; the two sides of the connecting rack are provided with a first connecting rod mechanism and a second connecting rod mechanism, which are correspondingly guided to the left connecting rod assembly and the right connecting rod assembly by the left lower arm and the right lower arm, and are hinged to eachother. The first connecting rod mechanism and the second connecting rod mechanism are in mirror symmetry along the vertical bisector of the connecting rack, and a damping spring is hinged between a pair of connecting rods in upper mirror symmetry. The invention is advantageous in that with the use of the connecting rod mechanism, the relation between the jumping amount of the vehicle and the compressing amount of the damping spring during the driving process is converted from a linear relation into a non-linear relation; damping performance is enhanced; the vehicle can be adapted to various road conditions, and the vibration during the vehicle driving can be reduced.

Description

Technical field [0001] The invention relates to a composite multi-link shock absorption mechanism for an inverted tricycle, belonging to the technical field of vehicle shock absorption. Background technique [0002] An inverted tricycle is a reverse tricycle in which the front wheel has two wheels side by side on the left and right, and the rear wheel has one wheel. Two of the front wheels have steering functions and the rear wheels have driving functions. In recent years, a variety of inverted tricycles have emerged, which have overcome the shortcomings of easy fall and poor stability, and can give users the same riding experience as a two-wheeler. It takes up a small space and is basically equivalent to a two-wheeler. Low cost, energy saving and environmental protection, are gradually being recognized by users. The dual shock absorption structure of the existing inverted tricycle front shock absorption structure is complex, heavy, high center of gravity, poor lateral and longi...

AI Technical Summary

Problems solved by technology

In the existing inverted tricycle front shock absorbing structure, the double shock absorbing structure is complex, heavy, high center of gravity, poor in lateral and longitudinal stability, and the stability of curves and high speed is poor in control precision. The existing inverted three wheel front single shock absorbing structure Weak progressiveness, unable to take into account the load characteristics of small stroke and large stroke
