Description
【Technical field】
The present invention relates to a kind of suspension frame structures, outstanding more particularly to a kind of high independence of new energy comfort used for buses
Frame.
【Background technology】
Automotive suspension is the important component for ensureing riding comfort.Meanwhile car suspension is used as vehicle frame (or vehicle body)
Make the power transmission parts connecting between axle (or wheel), and be the important component for ensureing bus driving safety, to weigh car
One of index of comfort.Due to currently researching and developing few, the alternative suitable tonnage of independent front suspension producer for 7~9 meters of cars
Independent front suspension less varieties cannot form industry-wide effect, limit the popularization of corresponding independent suspension.Domestic small tonnage at present
Independent front suspension is main or based on entity stub structure, due to being influenced by slewing journal structure, the setting of steel ring offset distance
On have limitation.Wheel mill tire situation cannot be theoretically avoided completely, vehicle can not obtain better steering gyrus positive force.
Most in independent suspension knuckle in existing structure still to carry entity stub, entire end of taking turns is rotated around stub
It realizes and turns to.Due to the presence of entity stub, pivot stud central point to wheel end installation position or big (the stub biasing of wheel hub surface distance
Away from big), cause to overcome steering moment is opposite to increase, needs to configure the turning machine system of bigger model.Before king pin offset weakens
The solely wheel self-aligning power of outstanding system is unfavorable for vehicle and travels handling and stability.Lower control arm on independent suspension
Axis pin cooperation bush structure is connected as between knuckle, i.e., upper lower control arm is rotated with knuckle around axis pin, axis pin with up and down
Control arm mounting hole uses abrasionproof bushing.Upper lower control arm mounting hole bushing, with after resultant motion for a period of time, easily occurs with axis pin
Abrasion generates gap.Front wheel Alignment Parameters will be caused to change in real time after generating gap, vehicle body generation will be caused to jolt and grind
Tire.Since T-type section connection structure and entity stub structure limit, disc centres are big to Hub mounting surface distance, in brake disc
Heart deviation tire force centre distance is big, increases the brake steer torque of vehicle braking generation, is unfavorable for flat when vehicle braking
Surely, hub bearing load while is also increased, the hub bearing service life is unfavorable for.
Therefore, it is necessary to provide a kind of independent suspension that new new energy comfort used for buses is high to solve above-mentioned ask
Topic.
