Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in detail.
According to an aspect of the present utility model, provide a kind of suspension structure of engine, as shown in Figure 1, this suspension structure of engine comprises:
Be connected with engine bed and the spacing backplate 1 of spacing suspension is carried out to engine bed;
With the polysulphide rubbers 2 that matches of the spacing backplate 1 of suspension, polysulphide rubbers 2 comprises: for the sulfuration upper plate 201 of fixing projection welding bolt 3 and locating dowel pin 4; For reducing the rubber block 202 of engine vibration amplitude; For the sulfuration lower plate 203 be connected with vehicle frame, wherein, sulfuration lower plate 203 two ends are provided with the limiting section 2031 for contacting with the spacing backplate 1 of suspension;
Be fixed in sulfuration upper plate 201, for connecting the projection welding bolt 3 of the spacing backplate 1 of suspension and engine bed; And
Be fixed on the locating dowel pin 4 in sulfuration upper plate 201, for positioning engine bed.
Particularly, in the utility model embodiment, suspend spacing backplate 1 and be provided with the first via hole passed for projection welding bolt 3; And for the second via hole that locating dowel pin 4 passes.Therefore, it is possible to be connected with engine bed by spacing for suspension backplate 1, by locating dowel pin 4, also reach certain positioning action.Wherein, the spacing backplate of this suspension 1 adopts Sheet Metal Forming Technology shaping, this technique not only technology maturation, is also convenient to control the quality of the spacing backplate 1 of suspension.In addition, when running into dynamic assembly and configuring different situations, according to practical application, certain improvement can be made to the shape of the spacing backplate 1 of suspension, therefore, it is possible to be suitable for different automobile types dynamic assembly, effectively shorten time-to-market, and saved cost of development.
Particularly, in the utility model embodiment, sulfuration upper plate 201, rubber block 202 and sulfuration lower plate 203 adopt sulfuration process one-body molded, have good connection function to engine bed and vehicle frame.And projection welding bolt 3 and locating dowel pin 4 are all fixed in sulfuration upper plate 201 by Type of Welding, therefore, good fixation is served to projection welding bolt 3 and locating dowel pin 4, and then good fixation can be played to the spacing backplate 1 of suspension, make to suspend spacing backplate 1 to can be good at coordinating with polysulphide rubbers 2, ensure that the control to driving engine displacement.
Further, in the utility model embodiment, the shape of rubber block 202 is parallelogram, and has certain elasticity, can either reduce the Oscillation Amplitude of driving engine, can eliminate again the flexure stress that suspension position limiting structure is subject to.It is appreciated of course that, in the utility model embodiment, the shape of rubber block 202 is not specifically limited.
Particularly, as shown in Figure 2, for the assembly drowing of suspension structure of engine in the utility model embodiment, wherein, suspend spacing backplate 1 by being fixed on projection welding bolt 3 on sulfuration upper plate 201 and locating dowel pin 4 and engine bed, sulfuration upper plate 201 forms rigidity and is connected, sulfuration lower plate 203 is reliably connected by lining cement with vehicle frame, therefore when suspending spacing backplate 1, with sulfuration lower plate 203, relative displacement occurring, there is the stressed generation deformation of elastomeric rubber block 202, make the limiting section 2031 of sulfuration lower plate 203 both sides, with suspension spacing backplate 1, rigid contact occur, motion stops, now, the maxim of stroke-limit can be reached.Therefore, by suspending cooperatively interacting of spacing backplate 1 and polysulphide rubbers 2, namely can control the displacement of the spacing backplate 1 of suspension, and then achieving the control to driving engine displacement.Therefore engine mounting position limiting structure is simple and reliable in the utility model embodiment, effectively can control the space displacement of cross-country car driving engine in severe road conditions, the concrete spacing requirement of same platform seriation vehicle can be adapted to again, reduce time-to-market and cost of development.
According to another aspect of the present utility model, additionally provide a kind of automobile, comprise above-mentioned suspension structure of engine, both met the requirement to driving engine space displacement, meet again the requirement of car load to suspension system NVH.
Above-described is preferred implementation of the present utility model; should be understood that the ordinary person for the art; can also make some improvements and modifications not departing under principle prerequisite described in the utility model, these improvements and modifications are also in protection domain of the present utility model.
