Abstract
The utility model relates to a suspension fork for an automobile, particularly a composite spring suspension for light weight automobiles suitable for the NHR and the NKR automobiles of Jiangxi ISUZU. In order to overcome the problems that the ride comfort and the comfortability are poor when the NHR and the NKR light weight carriage trucks of Jiangxi ISUZU travel on a poor road surface, the utility model adds partition board rubber pads between a plurality of plate springs and the axle on the basis of an original suspension for the automobile and added pad sheets between a third and a fourth plate springs of a rear suspension to differentiate the effect of a plurality of plate springs on idle load and heavy load, and meanwhile, a plurality of plate springs and the main size of a plurality of plate springs are designed and calculated again, and spring flat steels with much lower cost and the main size of the spring flat steels are selected. After the utility model is experimented, the ride comfort and the comfortability of the automobile are remarkably enhanced.
Description
The utility model relates to a kind of automotive suspension, the lilliput car complex spring suspension that particularly a kind of suitable Jiangxi Isuzu Motors NHR, NKR use.
Jiangxi Isuzu Motors NHR, NKR light-duty truck are that the Jiangxi car manufacturer is introduced the design paper of Japan Isuzu Motors car company and the product that manufacturing technology is produced.Though this light-duty truck has many superior Combination properties, but because also there is suitable gap in the pavement quality of developing country compared with developed countries, this automobile travels on relatively poor road surface, its ride comfort, traveling comfort obviously do not meet national standard and requirement, especially at the deadhead operation state, the lame sense of running is more outstanding, travels for a long time, and it is tired that passenger is felt.The regulation of automobile also can be affected tenure of use.By collecting the original-pack and homemade similar automotive suspension designing technique data of Japan Isuzu Motors, find out its design feature and main difference, go forward side by side trade drive test examination, engine bench test, ride comfort index evaluation and analyze in conjunction with the structure and the size of front suspension and rear suspension spring, find the material selection problem that front suspension and rear suspension laminated spring are not only deposited, (rigidity of material, intensity, toughness and specification, it is higher wherein especially to embody rigidity, between the laminated spring rigidity with do not matched by force environment); (for rigidity contacts, its traveling comfort obviously is affected between vehicle bridge and the laminated spring also simultaneously structure problem; When unloaded and heavily loaded, the stressed carrying of rear suspension is clearly distinguished); And everything finally all shows dimensionally, and size is the important behaviour in the design, for from the design feature of the existing automotive suspension of size reflection and with after the size after improving compares, the spy will have the main dimension of front suspension and rear suspension now and take passages.Front suspension is usable length, width, thickness, radian, the radius of curvature (unit of length is a millimeter) as shown in the table of each sheet laminated spring from top to bottom:
| Title | Usable length (L) | Width (b) | Thickness (h) | Camber (k) | Radius of curvature (R) |
| First laminated spring | 1140 | 60 | 9 | 82 | 2665 |
| Second laminated spring | 1145 | 60 | 9 | 73 | 2225 |
| The 3rd laminated spring | 790 | 60 | 9 | 42 | 1860 |
| The 4th laminated spring | 520 | 60 | 9 | 21 | 1610 |
| The 5th laminated spring | 250 | 60 | 8 | 4.5 | 1735 |
Rear suspension from top to bottom each sheet laminated spring usable length, width, thickness, haughty and aloof, radius of curvature is as shown in the table (unit of length is a millimeter):
| Title | Usable length (L) | Width (b) | Thickness (h) | Camber (k) | Radius of curvature (R) |
| First laminated spring | 1200 | 70 | 9 | 80 | 3050 |
| Second laminated spring | 1205 | 70 | 10 | 79 | 2280 |
| The 3rd laminated spring | 1000 | 70 | 10 | 61 | 2050 |
| The 4th laminated spring | 840 | 70 | 16 | 13 | 6785 |
| The 5th laminated spring | 440 | 70 | 14 | 4 | 6050 |
Above each several part main dimension is final design-calculated concentrated expression, so the unreasonable part that the each side designing institute occurs is embodied in the last size of implementing too.
The purpose of this utility model will provide a kind of lilliput car complex spring suspension exactly, design on the basis at Jiangxi Isuzu Motors NHR, NKR light-duty truck suspension frame structure, redefine material and scantling of structure, lilliput car complex spring suspension after the design is more become rationally, improve the ride comfort and the traveling comfort of automobile.
In order to achieve the above object, the technical solution of the utility model is achieved in that lilliput car complex spring suspension, comprises front suspension, rear suspension.Front suspension and rear suspension constitute by the center bolt of one group of laminated spring, tightening laminated spring, the spring buckle and the lining in the grasswort of two ends of adapter plate spring.Front suspension usable length, width, thickness, radian and the radius of curvature of each sheet laminated spring from top to bottom is as shown in the table: (unit of length is a millimeter):
| Title | Usable length | Width | Thickness | Camber | Radius of curvature |
| First laminated spring | 1140 | 60 | 9 | 98 | 2105 |
| Second laminated spring | 1145 | 60 | 9 | 96.5 | 1680 |
