Abstract
The invention relates to a mechanical combined independent suspension for automobile chassis. The mechanical combined independent suspension comprises two frame longitudinal members arranged in symmetry. At least one cross beam unit is disposed transversely between the frame longitudinal beams. A limiting device comprises a limiting base which abuts to an uppermost elastic steel plate; two U-shaped hoops which open up are symmetrically fastened to the limiting base; a rocker shaft unit is disposed below a leaf spring unit. Owning to the absence of the influence of a through shaft upon the frame, the height of the chassis can be more effectively reduced, and the minimum off-ground distance of a vehicle is never too small; under the action of a rocker, left and right wheels never interfere with each other during jumping, bumping and unbalance problems occurring during running of the vehicle can be effectively improved, and the problems such that the chassis is too high, the center of mass of the vehicle is high and running stability is proof are solved.
Description
Technical field
The present invention relates to a kind of automobile chassis mechanical combined type independent suspension.
Background technology
In known technical field, existing caravan back axle is supporting and low chassis intermediate axle towed vehicle used in suspension base
This be dependent formula mechanical suspension, during traveling exist jolt, energy imbalance.For the present generally existing chassis of towed vehicle
It is too high, riding stability difference the problems such as.The suspension of existing bottom of car generally reference axis (neither stand alone type machinery is outstanding
Frame), a wheel is respectively pacified at as one axle two ends in brief, the leaf spring connection in the axle arranged on left and right sides and left and right two longeron,
And with left and right two longeron into upper and lower overlaying state (see Figure of description 3,4), because leaf spring is upper and lower movable elastic component, be
Avoid, due to making axle and longeron occur to clash into when leaf spring moves up and down, just to improve vehicle frame in design, reserve vehicle frame with
Safe distance (representing A see the distance in Figure of description 3) between axle.Due to above characteristic, just necessarily composition chassis is too high.
Besides because each one wheel of peace in axle two ends, if next bounce on the wheel on the left side, the effect of the wheel on the right in axle
Under also have chain reaction, there is a problem of jolting during which results in traveling, riding stability it is poor.

Individual left and right symmetrical leaf spring component, the leaf spring component have some pieces of Elastic Steels being from top to bottom sequentially arranged
Plate, is provided with stopping means in the middle part of the spring steel plate, and the stopping means have the spring steel plate propped up positioned at the top
Spacing pedestal, tighten intrinsic two symmetrical and opening up U-shaped armful of bolts in the spacing pedestal, it is all elastic in same group
Steel plate penetrates the opening of two U-shaped armful of bolts,
It is provided with swing arm shaft assembly below the leaf spring component, the swing arm shaft assembly is with keeping with front beam
Parallel arm shaft, the two ends of the arm shaft extend through corresponding longitudinal beam, and equal in the end of the arm shaft
The swing arm that can be rotated around the central axis of arm shaft is provided with, the swing arm is connected with spacing pedestal by link assembly.
Further, it is as a kind of specific version, all elastic in heretofore described leaf spring component
The width of steel plate is consistent, and its length is from top to bottom successively decreased successively, and the spring steel plate is in bending straight down.
Further, it is contemplated that specific installation question, the present invention is in the leaf spring component positioned at the top
The level of spring steel plate is respectively provided on two sides with end anchorage, and the end anchorage be separately mounted to corresponding front beam,
On rear cross beam.
Further, as a kind of specific version, heretofore described link assembly has balancing stand, described flat
The upper end of weighing apparatus frame is hinged fixation with spacing pedestal, is connected with cradling piece, and institute in the lower end of the balancing stand by rotating shaft pin
The end for stating cradling piece is arranged in swing arm.
Further, in order to play further supporting role, the present invention is all provided with above the leaf spring component
Have a stable component, the stable component includes a right angle knee, at opening down and its right angle corner of the right angle knee with
Longitudinal beam rotates connection, and described right angle knee one end props up the top of spacing pedestal, and the other end is connected with by pivot pin
Hydraulic cylinder, the end of the cylinder barrel part of the hydraulic cylinder are arranged on longitudinal beam.
The invention has the beneficial effects as follows：Due to the impact without insertion axle to vehicle frame in the present invention, it is possible to more having
Effect ground reduces the height on chassis, and the minimum ground clearance of car also will not be too small, and in the presence of swing arm, left and right two-wheeled is upper and lower
It is non-interference during bounce, effectively can improve exist in vehicle travel process jolt, energy imbalance, also solve automobile
(including trailer) chassis is too high, and vehicle centroid is high, the problems such as riding stability difference.
