Abstract
The invention discloses a left suspension bracket of an automobile engine. The left suspension bracket of the automobile engine comprises a portal-shaped hanger (1), a U-shaped hanger (2) and a shock absorber. The shock absorber consists of a rubber block (3) and a metallic sheath (4) which covers the rubber block (3). The upper end of the U-shaped hanger (2) is welded on the metallic sheath (4). A shock-isolating damping pad (5) is installed between the shock absorber and the two side plates of the portal-shaped hanger (1). The shock-isolating damping pad (5) covers the upper parts of the shock absorber. Gaps L are left between the shock-isolating damping pad (5) and the two side plates of the portal-shaped hanger (1). The shock-isolating damping pad (5) is made of a nylon material. By controlling the shock absorber at the swing-up position of the shock absorber, the swing amplitude of the shock absorber is controlled within a small range, the shock is reduced, the driving comfort is improved and the left suspension bracket is the first in car application.

Technical field
The invention belongs to auto parts and components, specifically, is a kind of left mounting bracket that is used to install motorcar engine.
Background technology
Driving engine all through flexible-disc joint to vehicle body, in order that buffering vibration, most civil caies all are to serve as through rubber to connect buffering.Engine mounting is the important component part of car load vibration control, to improving automobile NVH characteristic, satisfies good travelling comfort and has important effect.
Car engine left suspension support as shown in Figure 1 is made up of " Jiong " shape hanger, " U " shape hanger and vibration-damped component.Vibration-damped component is made up of the rubber block metallic sheath outer with wrapping in rubber block, and this vibration-damped component hangs on the biside plate of " Jiong " shape hanger through the bearing pin that is arranged in the rubber block, and the upper end of " U " shape hanger is welded on the metallic sheath.The horizontal plate of " Jiong " shape hanger is provided with the installation double-screw bolt, is used for " Jiong " shape hanger is connected to the body mount support, and the horizontal plate of " U " hanger is provided with project-welding nut, is used for " U " hanger is connected to the change-speed box mounting bracket.Because rubber block has the energy-obsorbing and damping effect, this flexible-disc joint mode is buffering vibration to a certain extent, weakens driving engine and is delivered to the vibrational energy on the vehicle body.
After the vibration transfer of driving engine arrives on " U " shape hanger; Vibration-damped component swings in " Jiong " shape hanger in company with " U " shape hanger; When swinging to left and right end position; Vibration-damped component and the collision of " U " shape hanger, and the partial vibration energy after will weakening is delivered on the vehicle body through " U " shape hanger.Vibration-damped component rises after the pendulum, and its oscillation frequency can increase gradually, in case identical with the rhythm of engine, just produce resonance, the vibrational energy that is delivered on the vehicle body can increase suddenly, also has tangible vibration sense at steering position, even has numb
Sensation.
Summary of the invention
The objective of the invention is vibration-damped component to be controlled, the amplitude of fluctuation of vibration-damped component is controlled in the small range, avoid the vibration-damped component oscillation frequency excessive and produce resonance through the pendulum position of rising at vibration-damped component.
For achieving the above object; A kind of car engine left suspension support of the present invention; Comprise " Jiong " shape hanger (1), " U " shape hanger (2) and vibration-damped component; Said vibration-damped component is by rubber block (3) and wrap in the outer metallic sheath (4) of rubber block (3) and forms, and this vibration-damped component hangs on the biside plate of " Jiong " shape hanger (1) through being arranged on the interior bearing pin (6) of rubber block (3), and the upper end of said " U " shape hanger (2) is welded on the metallic sheath (4); It is characterized in that: between the biside plate of said vibration-damped component and " Jiong " shape hanger (1), vibration isolation damping pad (5) is housed; This vibration isolation damping pad (5) wraps in the top of vibration-damped component, leaves gap L between the biside plate of vibration isolation damping pad (5) and " Jiong " shape hanger (1), and vibration isolation damping pad (5) adopts nylon material to process.
Principle of work: after the vibration transfer of driving engine arrives on " U " shape hanger; Be arranged on the vibration isolation damping pad between vibration-damped component and " Jiong " shape hanger biside plate; In a pendulum position vibration-damped component is controlled; The amplitude of fluctuation of vibration-damped component is controlled at small range, is i.e. in the gap L between the biside plate of vibration isolation damping pad and " Jiong " shape hanger, avoids the vibration-damped component Oscillation Amplitude excessive and produce resonance.
The left and right sides of said metallic sheath (4) is extended with arc journal stirrup (4a), and the middle part width of said arc journal stirrup (4a) is greater than the front and back width of arc journal stirrup (4a); The cross-sectional plane of said vibration isolation damping pad (5) is curved; The arc-shaped cavity (5a) that holds vibration-damped component is dug in the center; The left and right sides of said arc-shaped cavity (5a) is provided with the arc chute (5b) that supplies arc journal stirrup (4a) to snap in; The middle part degree of depth of said arc chute (5b) is greater than the front and back degree of depth, said arc-shaped cavity (5a) and the coaxial setting of arc chute (5b).During installation, the arc chute of vibration isolation damping pad snaps in along the arc journal stirrup of metallic sheath, finally makes the middle part of arc journal stirrup fall into arc
The middle part of shape chute, such mounting structure has been avoided radially rotating and moving axially between vibration-damped component and the vibration isolation damping pad.
Be preferably, the gap L between the biside plate of said vibration isolation damping pad (5) and " Jiong " shape hanger (1) is 0.5 ± 0.3mm, and vibration isolation damping pad (5) employing Shore hardness HS is that 90 ± 5 ° nylon material is processed.
Remarkable result of the present invention is: novel, design is ingenious, through swing, thereby reduce vibration, improve the traveling comfort of driving from pendulum position control vibration-damped component, and on passenger car applications, still belong to and initiating.
