Description
[technical field]
The utility model relates to a kind of suspension frame structures, more particularly to a kind of high independence of new energy comfort used for buses
Suspension.
[background technique]
Automotive suspension is the important component for guaranteeing 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 guaranteeing bus driving safety, to measure 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 have entity stub, entire end of taking turns is rotated around stub

Away from big), cause to overcome steering moment is opposite to increase, needs to configure larger number turning machine system.Before king pin offset weakens
The solely wheel self-aligning power of outstanding system, is unfavorable for that vehicle driving is handling and stability.Lower control arm on independent suspension
Pin shaft cooperation bush structure is connected as between knuckle, i.e., upper lower control arm and knuckle are rotated around pin shaft, pin shaft and up and down
Control arm mounting hole uses abrasionproof bushing.Upper lower control arm mounting hole bushing and pin shaft cooperative movement for a period of time after, easily occur
Abrasion generates gap.It will lead to Front wheel Alignment Parameters behind generation gap to change in real time, will lead to vehicle body generation and 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, while also hub bearing load is increased, the hub bearing service life is unfavorable for.
Therefore, it is necessary to provide the high independent suspension of the new new energy comfort used for buses of one kind to solve above-mentioned ask
Topic.
