Abstract
A supporting arm of an automobile engine comprises a base made of a metal plate, wherein one end of the base is provided with a support, the other end of the base is provided with three connection through holes for being connected with the engine, the outer surface of the support is provided with an isosceles-trapezoid groove, and a fixing through hole is formed in the center of the groove of the support and used for being connected with a gearbox. The supporting arm of the automobile engine has the advantages that by means of the isosceles-trapezoid groove and the fixing through hole in the support, the supporting arm is firmly connected with the gearbox; by means of the through holes arranged in a regular triangle shape, the supporting arm is firmly connected with the engine; vibration frequency of an automobile engine assembly is provided, the point of resonance of an automobile engine power assembly and the finished automobile is avoided, and noise can be lowered down when the automobile engine runs at a high speed. Furthermore the supporting arm of the automobile engine is low in cost, easy to use and obvious in effect.
Description
Technical field:
The utility model relates to a kind of automotive engine trailing arm.
Background technology:
In the vehicle such as lilliput car, manned vehicle, driving engine produces power, passes to axle drive shaft by power-transfer clutch, change-speed box, and propulsive effort is assigned to the left and right jack shaft that turns to by diff, drives vehicle wheel rotation by rotating drive semiaxis, makes automobile produce fortune.
Turn to jack shaft to be divided into left half axle and right axle shaft, right axle shaft, because distance wheel side is far away, considers to come the Catching-rabbits with two sectional type Bu for engineering more, and wherein one section is the transmission shaft of change speed gear box to midship mounting, and another section is the jackshaft that midship mounting arrives wheel side.
Right axle shaft midship mounting is that trailing arm supports, and therefore the left side of jackshaft is hunched beam, and one end of hunched beam is fixed on engine body and stretches out the left side of cantilever with fixed conveyor semiaxis, and jackshaft right side is connected on wheel.This supporting construction is because the reason of cantilever beam makes left side support stiffness on the low side, cause jackshaft entirety constraint model frequency less, under the excitation of the certain rotating speed of driving engine, easily there is jackshaft resonance, in car, produce low frequency noise, this vibration and noise reach the human discomfort that very easily causes chaufeur or occupant in car simultaneously.
Utility model content:
Technical problem to be solved in the utility model is to overcome existing technological deficiency, and a kind of a kind of automotive engine trailing arm rational in infrastructure, simple to operate, easy to use is provided.
Technical problem to be solved in the utility model adopts following technical scheme to realize:
A kind of automotive engine trailing arm, comprise base, described base is metal sheet, described base one end is provided with support, the described base other end is provided with three connecting through holes, and connecting through hole is for connecting engine, and described rack outer surface is provided with isosceles trapezoid groove, the groove center of described support is provided with fixed via, and fixed via is used for connecting change speed gear box.
As optimal way, described support vertical, in base, is convenient to install.
As optimal way, three described connecting through holes are the arrangement mode of equilateral triangle, utilize leg-of-mutton stability, thereby have guaranteed the stability that trailing arm is connected with driving engine.
The beneficial effects of the utility model are: the utility model utilizes trapezoidal groove and the fixed via on support, trailing arm and change speed gear box are stablized to be connected, utilization is the through hole that equilateral triangle is arranged, bracket and driving engine are stablized to be connected, thereby provide the oscillation frequency of vehicular engine assembly, avoid the resonance point of vehicular engine dynamic assembly and car load, make vehicular engine in high engine speeds operation process, can reach the object that reduces noise.In addition, the utility model cost is lower, implements simply successful.
Accompanying drawing explanation:
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the utility model front side structure schematic diagram;
Fig. 2 is the utility model rear structure schematic diagram.
The specific embodiment:
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figures 1 and 2, a kind of automotive engine trailing arm, comprise base 2, described base 2 is metal sheet, and described base 2 one end are provided with support 3, and described base 2 other ends are provided with three connecting through holes 1, connecting through hole 1 is for connecting engine, described support 3 outside faces are provided with isosceles trapezoid groove 5, and groove 5 centers of described support 3 are provided with fixed via 4, and fixed via 4 is for connecting change speed gear box.Described support 3 is perpendicular to base 2.Described three connecting through holes 1 are equilateral triangle to be arranged, and utilizes leg-of-mutton stability, thereby has guaranteed the stability that trailing arm is connected with driving engine.
More than show and described groundwork of the present utility model and principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification sheets, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
