Abstract
The invention discloses a single-point suspension of uniform-cross section springs. The single-point suspension of the uniform-cross section springs comprises a uniform-cross section leaf spring assembly, a first bolt clamp, a second bolt clamp and a third bolt clamp. The first bolt clamp and the second bolt clamp are arranged at the two ends of the leaf spring assembly and used for being fixedly connected with axles at the two ends; and the third bolt clamp is arranged in the middle of the leaf spring assembly and used for being fixedly connected with a center shaft. The suspension of 17 leaf springs is changed into the single-point suspension of 9 uniform-cross section springs, the material specification is unified, so that the problem that running stability is affected by the fact that the total thickness of the leaf springs is too large as too many leaf springs are arranged and thus the height of center of gravity of the vehicle is too high is solved, and the weight of the leaf springs is decreased under the premises of guaranteeing the reliability and not shortening the life of the leaf springs (i.e. not increasing the design stress). The material saving effect is obvious, and the fuel consumption is favorably decreased.
Description
Technical field
The present invention relates to auto parts machinery field, more particularly to a kind of uiform section spring single-point suspension.
Background technology
At present, automobile single-point suspension is hung using leaf spring, and design load is 32 tons, is generally hung using 17 leaf springs, and this spring hangs transmission torque, relaxes impact.But as leaf spring is relatively more, cause 17 multiple-leaf spring total thicknesses excessive, waste of material is serious, and arrangement tailheaviness excessive height, so that affect driving stability sex chromosome mosaicism；Increase the consumption of fuel oil；Technics comparing trouble and material specification is 3 kinds, in manufacture.
Accordingly, it would be desirable to a kind of spring of the less driving stability of plate spring assembly thickness hangs.
The content of the invention
In view of this, the technical problem to be solved is to provide a kind of single-point suspension of the less driving stability of plate spring assembly thickness.The automobile suspension arrangement replaces existing 17 chip automobile suspension arrangement leaf spring using nine uniformsection leaf springs.The object of the present invention is achieved like this：
A kind of uiform section spring single-point that the present invention is provided hangs, including uiform section lead spring assembly, the first bolt clamp, the second bolt clamp, the 3rd bolt clamp；
The first bolt clamp, the second bolt clamp are respectively arranged at uiform section lead spring assembly two ends for being fixedly connected with two ends wheel shaft respectively；The 3rd bolt clamp is arranged in the middle part of uiform section lead spring assembly for being fixedly connected with axis.
Further, the lead spring assembly is nine uniformsection leaf springs.
Further, the lead spring assembly includes seven to ten uniformsection leaf springs.
Further, the first clamp sleeve pipe is arranged between the first bolt clamp and the 3rd bolt clamp for fixing lead spring assembly；The second clamp sleeve pipe is arranged between the second bolt clamp and the 3rd bolt clamp for fixing lead spring assembly.
Further, the first bolt clamp includes leaf spring end cap, leaf spring backing plate, wheel shaft pressuring plate and the first bolt；The leaf spring end cap is arranged at lead spring assembly upper end, the leaf spring backing plate is arranged at lead spring assembly lower end, the wheel shaft pressuring plate is arranged at below wheel shaft, first bolt is symmetrically arranged with wheel shaft pressuring plate, and is fixed on lead spring assembly for one end of lead spring assembly is fixed on wheel shaft through leaf spring backing plate.
Further, the second bolt clamp includes leaf spring end cap, leaf spring backing plate, wheel shaft pressuring plate and the second bolt；The leaf spring end cap is arranged at lead spring assembly upper end, the leaf spring backing plate is arranged at lead spring assembly lower end, the wheel shaft pressuring plate is arranged at below wheel shaft, second bolt is symmetrically arranged with wheel shaft pressuring plate, and is fixed on lead spring assembly for one end of lead spring assembly is fixed on wheel shaft through leaf spring backing plate.
The beneficial effects of the present invention is：(17) suspensions of multi-disc leaf spring are changed to the suspension of 9 chip uiform section spring single-points by the present invention；Solve because 17 multiple-leaf spring total thicknesses are excessive, arrangement tailheaviness excessive height affects driving stability sex chromosome mosaicism；On the premise of ensureing reliability, not reducing life of plate spring (not improving design stress), it is distributed using uiform section spring iso-stress, the characteristics of stock utilization is high, reduces leaf spring weight.And due to leaf spring lighter in weight, can reduce by about 40% deadweight compared with multiple-leaf spring, advantageously reduce the consumption of fuel oil；As weight reduction, nonspring carried mass are reduced, plate spring assembly thickness is less, can reduce the center of gravity of car load, improves riding stability.Lightweight, energy-conservation, riding stability, comfortableness are improved.Due to there is grease to be lubricated leaf spring, between leaf spring, switch to lubricating status from dry condition, eliminate noise, the spring mounted service life of extending steel plate.
