Description
Technical field
This utility model is related to technical field of vehicle, more particularly to a kind of left suspension stud, a kind of and left suspension
The matching used left mounting bracket of stud, a kind of left mounting bracket component, a kind of left mounting assembly and a kind of vehicle.
Background technology
At present, developing rapidly with the improvement of people's living standards and automobile industry, the popularity of automobile is more next
It is higher, meanwhile, consumer to automobile overall performance, such as requirement of vibration proof performance also more and more higher.Engine Mounting System
It is the important component part of engine application engineering, it is primarily served the purpose of：1. (power assembly is general to support and fix power assembly
Including electromotor, variator etc.), under electromotor itself vibrational excitation and extraneous load effect, between power assembly and chassis
Relative motion can occur, and Engine Mounting System has the function of suppressing power assembly relative motion, makes power assembly each
Displacement on direction is in the scope of design, it is to avoid power assembly under the various operating modes of running car with vehicle body and chassis on
Part is interfered or collided；2. vibration isolation and damping, engine mounting mainly reduces the vibrations of two kinds of excitations, one kind be electromotor from
The excitation of body, another kind is automobile external excitation, is mainly caused by Uneven road, is passed to by wheel suspension and vehicle frame dynamic
The vibration of power assembly, reduces vibration noise；3. balanced power assembly output torque is produced counteracting force and power assembly it is used
Property power, Engine Mounting System must have sufficient intensity, to overcome maximum produced during power assembly maximum output torque anti-
The inertia force of power assembly under active force and vehicle running state.
At present engine left suspension typically adopts " integral type " structure, its mainly by left suspension body by press-loading process and
Left suspension vehicle body connecting bracket is assembled together, and one is connected to by stud between left suspension body and left mounting bracket
Rise.But, there is certain deficiency in this left suspension " integral type " design, i.e.,：
1., easily there is stress concentration in low intensity, and causes Cracking Failure problem.
If stud selection is improper or diameter of bolt design is less, it will causes stud to ftracture, such as exists
Under engine idle or vehicle driving-cycle, when left mounting bracket and left suspension stud receive power assembly maximum output torque
The inertia force load effect of produced maximum counteracting force or power assembly, answers left mounting bracket and left suspension stud
Power is concentrated, and causes Cracking Failure.
2. suppress left suspension that the selection of nut screwing clamping torque is installed, easily cause left suspension installation nut and return pine.
If stud strength grade selects the improper or diameter of bolt, and design is less, can affect left suspension that nut is installed
The selection of screw-down torque, easily causes installation nut and returns pine.Left suspension installation nut returns pine following impact：First, can make
Power assembly system produces abnormal sound, and engine mounting vibration isolation and damping declines affect car load NVH performances；Secondly, left suspension is installed
Nut loosening aggravates seriously power assembly relative motion, prevent engine mounting total from playing support very well and fixed power
Into effect, and then left mounting bracket or stud Cracking Failure problem can be caused.

Three connection corners 21, so, left mounting bracket 12 is formed as triangular structure such that it is able to be obviously improved left mounting bracket
12 self-strength, wherein, stud installing hole 7 is formed in boss portion 20, and is formed with dress on each connection corner 21
Distribution, the pilot hole coordinates with bolt, the left assembling of suspension 12 can be navigated on variator.
In addition, increasing left mounting bracket 12 relative to the height for changing the higher material of intensity or increase boss portion 20
Bulk strength for, by being circumferentially formed with radially outer support on the aperture of stud installing hole 7
Locating surface 8, can lift local strength while cost-effective, and as above, enable to left mounting bracket 12 light
Quantify.
Another further aspect, this utility model provides a kind of left mounting bracket component, the structure with reference to shown in Fig. 3, the left suspension
Carriage assembly 10 includes the left suspension stud 11 and the left mounting bracket 12 described in any of the above described in any of the above, its
In, as shown in figure 3, the screw thread of tack thread segment 2 coordinates in stud installing hole 7, and as shown in fig. 6, strengthen the He of protuberance 4
Locating surface 8 is supported to coordinate.
So, by strengthening protuberance 4 and supporting the cooperation of locating surface 8, left mounting bracket 12 and left suspension can be increased
The contact area of stud 11, improves the thread of the tack thread segment 2 of stud installing hole 7 and left suspension stud 11
Stress level, this clamp nut 16 for contributing to left suspension selects larger screw-down torque, solves because of left suspension clamp nut
Return the problem of power assembly abnormal sound, left mounting bracket or left suspension stud cracking that pine is caused.
Another further aspect, this utility model provides a kind of left mounting assembly, the structure with reference to shown in Fig. 4 and Fig. 5, the left suspension
