Abstract
The utility model provides an anti-rotation engine suspension, which comprises a suspension bracket, a suspension soft pad assembly and fasteners connecting the suspension bracket and the suspension soft pad assembly. The fasteners comprise a hex nut and a bolt. The suspension bracket is provided with a hexagonal sink hole in a position for assembling the nut, the hex nut is arranged in the hexagonal sink hole, and the distance s1 of two parallel edges of the hexagonal sink hole falls between the distance s of two parallel edges of the hex nut and the distance e of the other two farthest vertexes, i.e. s1 is more than s and less than e. The utility model realizes the purpose of preventing the nut from rotating via matching of the hexagonal sink hole on the suspension bracket and the hex nut with no additional arrangement of other parts but reduction of the material of the suspension bracket. Therefore, the utility model can reduce the cost and improve the assembly precision while achieving identical functions.
Description
Technical field
The utility model relates to a kind of engine mounting, and particularly a kind of have suspending of anti-rotating function.
Background technology
At present, the driving engine of vehicle and dynamic assembly thereof are installed on the car chassis by suspension system, and suspension system has three big functions: support, spacing, vibration isolation.Suspend and need bear the weight of driving engine, under situation about being subjected under the various exciting force effects, should be able to limit its maximum displacement by actv., to avoid taking place and being close to the interference of part, simultaneously, it should have good vibration isolation effect.
Suspension system generally comprises four of front, rear, left and right and suspends, each suspends and comprises suspending soft cushion assembly and mounting bracket two parts, suspending soft cushion assembly one end is installed on the car body, mounting bracket one end is installed on the driving engine (two on the contrary also can), and the other end of mounting bracket then is connected with screw bolt and nut with the other end of suspending soft cushion assembly.Because the restriction in space, the installation difficulty of mounting bracket is bigger, and common have following two kinds of mounting meanss: after 1, earlier bolt being passed support and installing, again with nut screwing clamping in bolt; 2, nut is welded on a side of support, passes bolt from opposite side and tighten installation.But these two kinds of methods all have shortcoming separately: at first kind of mounting means, when bolt was put on the back fastening nut, the opposite side bolt of support also can be along with nut rotates together, then needed this moment two people to cooperate and finished; At second kind of mounting means, do not have together the phenomenon of rotating between the bolt, but because the welding error is bigger, the screw that may cause the nut that welds not with the bracket bolt hole on same straight line, cause bolt that the consequence of difficulty is installed.Therefore, above-mentioned scheme exists the loaded down with trivial details of fitting process together, the problem of inefficiency.
The patent No. is that the patent document of ZL 200720196767.1 discloses a kind of mounting bracket with rotation-preventing mechanism.The technical matters that this structure exists is that related parts are more, anti-rotor, anti-switch block is wherein arranged, and adopt welding process easily to produce distortion, has increased operation and cost, influences fastener precision and assembly quality.
Summary of the invention
The purpose of this utility model is the problem that exists at prior art to provide a kind of engine mounting with anti-rotating function, with solve prevent that in the mounting bracket fitting process nut from rotating in, can cost-cutting, improve assembly quality.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is:
A kind of engine mounting with anti-rotating function, it comprises mounting bracket, suspending soft cushion assembly and mounting bracket and suspending soft cushion assembly is carried out coupled fasteners that described fastener is hexagonal nut and bolt; The connection suspending soft cushion assembly end of described mounting bracket has the U-shaped link slot, the coupling end of suspending soft cushion assembly puts in the U-shaped link slot, bolt pierces into from a side of U-shaped link slot, and passing the coupling end of putting cushion assembly and the opposite side of U-shaped link slot successively, traversing through end is tightened fixing by hexagonal nut;
It is characterized in that, the position of assembling nut has a hexagonal counterbore on described mounting bracket, described hexagonal nut falls into described hexagonal counterbore, two parallel edges of described hexagonal counterbore apart from s1 between two parallel edges of hexagonal nut apart from s and in addition two farthest vertices apart from e between, be s＜s1＜e, by the rotation of hexagonal counterbore restriction hexagonal nut.
Design-calculated of the present utility model suspends by hexagonal counter bore structure on mounting bracket and the hexagonal nut incompatible purpose that prevents that nut from rotating that reaches that matches, do not need to increase parts, reduced the mounting bracket material on the contrary, reaching under the prerequisite of identical function, can cost-cutting, and improve assembly precision.
Description of drawings
Fig. 1: the structural representation that originally suspends.
Fig. 2: this is suspended at the cutaway view of assembled portion.
Fig. 3: the hexagonal counterbore that this suspends matches with hexagonal nut and reaches the schematic diagram of anti-rotation.
The specific embodiment
As shown in Figure 1, engine mounting comprises mounting bracket 2, suspending soft cushion assembly 3 and hexagonal nut 1 that is connected both and bolt 4.The connection suspending soft cushion assembly end of mounting bracket 2 has the U-shaped link slot, the coupling end of suspending soft cushion assembly 3 puts in the U-shaped link slot, bolt 4 pierces into from a side of U-shaped link slot, and passing the coupling end of putting cushion assembly 3 and the opposite side of U-shaped link slot successively, traversing through end is tightened fixing by hexagonal nut 1.The other end of suspending soft cushion assembly 3 is installed on the car body, and the other end of mounting bracket is installed on the driving engine.
Hexagonal counterbore 5 has certain assembly relation with hexagonal nut 1, as shown in Figure 3, two parallel edges of hexagonal counterbore 5 apart from s 1 between two parallel edges of hexagonal nut 1 apart from s and in addition two farthest vertices apart from e between, be s＜s1＜e, can put into the hexagonal counterbore 5 of mounting bracket 2 and can be around its axle center rotation to guarantee hexagonal nut 1.When swivel bolt 4, hexagonal nut 1 can not tight a bolt 4 thereby reach, the purpose of fastening quickly and easily mounting bracket 2 and suspending cushion 3 along with bolt 4 rotations because of the fit structure of the hexagonal counterbore 5 of mounting bracket 2.
