Description

Flexible rear axle mechanism Technical Field The utility model relates to the technical field of rear axles of vehicles, in particular to a flexible rear axle mechanism. Background The rear axle of the vehicle is arranged at the tail part of the vehicle and is used for installing brackets of two rear wheels. In the prior art, part rear axle adopts two crossbeams to rotate and sets up on the middleware, places two rear wheels in two crossbeam both ends again, when making the electric motor car skid, two crossbeams can carry out the adaptation adjustment (interval between two crossbeams changes), makes the condition that reduces to skid take place (prevent sideslip mode), improves the security of driving. Above-mentioned rear axle structure, though can reduce the condition that the vehicle skidded through the adjustment of crossbeam interval and take place, when the vehicle was gone on in level road surface, because the crossbeam interval is movable, lead to the vehicle not steady enough, influence riding experience. In view of the foregoing, there is a need for a rear axle mechanism that is flexible to address the above-mentioned issues. Disclosure of utility model The present utility model solves the problems of the prior art with the following technical structure.
