Technical field
The present invention relates to a kind of suspension transfer for the straight drive electric automobile of wheel hub, belong to automobile hanging and steering machine
Structure technical field.
Background technology
In order to coordinate traditional transmission mode, the drive axle of existing automobile chassis, adopting lateral suspension more, existing electronic
Automobile is also to continue to use this hang, and this hang limits the stroke of wheel vibration damping motion and transports up and down in wheel
Lateral displacement can be occurred when dynamic to cause tire in horizontal abrasion, the Plane of rotation of wheel cannot keep vertical with ground level simultaneously
Thus causing to travel stability decline and transmission efficiency reduction；In order to reduce this impact, some suspensions as inferior in McGee, many are invented
The modes such as hanging, this causes again, and mechanism is complicated, part increases, the rising of cost weight, reliability decrease, lubricating difficulties, and
And cannot thoroughly solve the abrasion of parts, especially it is difficult to larger cushioning stroke.
In Conventional drum vehicle, the direction stability in traveling is to rely on the constant speed drive of left and right sides wheel, by machine
Come to ensure, mechanical differential gear box determines when single wheel skids, opposite side car for the mechanical constraint of tool differential mechanism and steering machine
Wheel can run out of steam；And necessarily lead to direction unstability in Uneven road and when road medium changes, vehicle frame is left simultaneously
The inequality of the load-carrying of right both sides or abrasion will also result in travel direction deviation, and these all make under driving safety and smoothness
Fall.
In the electric automobile of wheel hub direct drive, the equilibrium problem of both sides wheel driving force and driving current is difficult to solution
Certainly, the direction unstability that road shocks traditionally cannot be overcome by the way of E-Diff to cause, also cannot adapt to load-carrying and become
Change the change with road surface medium, therefore never reach practical degree.
