Abstract
The utility model relates to a kind of foldable chassis for dilly, and folding stand is by pedestal, and rear suspension and front suspension form.Forward and backward suspension is connected on pedestal by S. A..On rear suspension, the parts such as installing wheel, motor, battery, provide power for travelling.When folding, dwindle wheel base and the track front of vehicle frame, save that the horizontal projected area that takies is convenient stops, and wheel base and the track front of vehicle frame strengthens while launching, improves the riding stability of vehicle.
Description
Technical field
The utility model relates to a kind of foldable chassis for dilly, dwindles that the horizontal projected area that takies is convenient stops when folding, and wheel base and the track front of vehicle frame strengthens while launching, improves the riding stability of vehicle.
Background technology
In modern society, the use of automobile is increasingly extensive, also brought many inconveniences after offering convenience, and wherein parking difficulty becomes topmost problem.And traditional subcompact has small size in possessing the feature of the occupation of land of saving, cause the safety of running at high speed of vehicle to be difficult to ensure because the distance between wheel is too little, become the difficult problem in design.
Summary of the invention
For solving the above problems, the utility model proposes a kind of scheme of folding stand.Adopt this programme subcompact in the time parking, the plan area taking significantly can be dwindled, and the wheel base of vehicle frame and track front strengthen stable support can be provided for running at high speed while travelling.
Specifically, folding stand is by pedestal, and rear suspension and front suspension form.Forward and backward suspension is connected on pedestal by S. A..On rear suspension, the parts such as installing wheel, motor, battery, provide power for travelling.Front suspension is made up of two front wheel arms, two front swing arms, two front-wheels, and front wheel arm is connected on pedestal by front wheel arm installation shaft, and driver train can drive two front wheel arms around front wheel arm installation axis rotation separately, realizes the folding of vehicle frame and launches; Front swing arm is connected by front swing arm installation shaft with front wheel arm, and driver train can drive front swing arm, around front swing arm, axis rotation is installed, and the axis rotating while making front-wheel steering motion remains the position perpendicular to ground; Front swing arm is connected with front-wheel, and driver train can drive front-wheel to rotate and realize divertical motion around the axis of front swing arm and front-wheel adapter shaft.Rear suspension is by being connected on pedestal, and driver train can drive rear suspension to rotate around S. A., realizes the folding of vehicle frame and launches.Front wheel arm installation shaft respectively left back below and right back below is stretched out, and the axis that front swing arm peace rotating shaft and front-wheel steering motion are rotated has angle, when making vehicle frame folding, these orientation and angle combined action dwindle wheel base and track front, reduce floor area, and amplify wheel base and track front while launching.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described, be necessary to be pointed out that at this present embodiment, only for invention is further described, can not be interpreted as the restriction to the utility model protection domain.The person skilled in the art in this field can make some nonessential improvement and adjustment according to the content of the invention described above.
Schematic diagram when being illustrated in figure 1 vehicle frame and launching, folding stand is by pedestal 1, and rear suspension 3 and two front wheel arms 2, two front swing arms 9, two front-wheels 4 form.Front wheel arm 2, rear suspension 3 are connected on pedestal 1 by pacifying separately rotating shaft, the parts such as installing wheel, motor, battery on rear suspension 3.Front wheel arm 2 is connected on pedestal 1 by front wheel arm installation shaft 5, and driver train can drive two front wheel arms 2, around front wheel arm separately, axis 7 is installed and rotate, and realizes the folding of vehicle frame and launches; Front swing arm 9 is connected by front swing arm installation shaft 12 with front wheel arm 2, and driver train can drive front swing arm 9, around front swing arm, axis 10 is installed and rotate; 9 of front swing arms are connected with front-wheel 4, front swing arm wheel axis 10 coincides with front-wheel pivot center 11, front-wheel 4 can be realized shock-absorbing function along front swing arm wheel axis 10 up-and-down movements, and driver train can drive front-wheel 4 to rotate to realize with the axis (front swing arm wheel axis 10 or front-wheel pivot center 11) of front-wheel 4 adapter shafts around front swing arm 9 and turn to.Rear suspension 3 is by being connected on pedestal 1, and driver train can drive rear suspension 3 to rotate around rear suspension rotating shaft 6, realizes the folding of vehicle frame and launches.Front wheel arm installation shaft 5 respectively left back below and right back below is stretched out, and the angle of launching is backward α, and the outer angle of launching is β (Fig. 5) mutually; And front swing arm installation shaft 12 has angle with front-wheel pivot center 11, its complementary angle is γ (Fig. 8), and wherein β equates with γ or its difference is just the leaning angle of wheel.
In front-wheel 4, there is wheel hub motor, can drive front-wheel 4 to rotate, match with the wheel movement on rear overhang 3, realize the folding of vehicle frame and launch (dwindle or expand wheel base and track front).When front wheel arm 2 and rear suspension 3 are during around installation shaft rotation separately, front swing arm 9 also rotates and makes the rotation axis (front-wheel pivot center 11) of front-wheel 4 divertical motions remain the position perpendicular to ground under driver train effect, front-wheel 4 is followed folding or is launched to move and adjust the direction angle of front-wheel 4, makes the relative ground of front-wheel 4 keep pure rolling.
