Technical field
The utility model vehicle chassis technology field, and in particular to general before and after a kind of wheel-hub motor driven vehicle to connect more
Bar suspension fork mechanism.
Background technique
Hub motor technology is that the motor assembly for being integrated with retarder is directly arranged in wheel hub, by 4 wheel motors
4 wheels are directly driven, compared to for traditional electric car, hub motor technology eliminates differential mechanism, semiaxis even two stage speed change
Device, complete vehicle structure are greatly simplified.However, concentrating motor-driven vehicle relative to internal combustion engine driving or tradition
It says, each component of wheel side suspension of In-wheel motor driving, such as control arm, damper, spring, arrangement space is nervous, leads to chassis
System easily interferes, and suspension adaptability difficulty of matching is big.
In addition, the chassis unsprung mass of four-wheel In-wheel motor driving is big, it is unfavorable for the ride comfort of suspension and handling.Suspension
As the guiding mechanism of tire motion and the transmission mechanism of power.Especially front suspension is related to its lower control arm pair of divertical motion
Front suspension divertical motion influences very big.From the perspective of dynamic suspension system of vehicles, the state of suspension kingpin offset negative value is more managed
Think.But hub motor suspension arrangements in the prior art, compared to conventional suspension, because to match hub motor, wheel hub electricity
Casing body, cooling water pipe and harness etc. occupy suspension and take turns the arrangement space on side, and kingpin offset is caused to be difficult to be arranged to manage
Think state.To generate steering effect, be degrading handling stability in vehicle braking or unequal two sides wheel braking force
Energy.Meanwhile passenger car vehicle suspension fork mechanism mostly uses the form of preceding double wishbone suspension, rear multi-link lever suspension fork in the prior art, it is preceding
Each component of rear suspension substantially cannot be general, and fore suspension and rear suspension amount of parts is more, causes design, production, logistics cost higher.
