Description
Technical field
The present invention relates to bearing device for automobile engine, particularly a kind of heavy-duty truck engine front support device.
Background technology
Bearing device for automobile engine not only will bear the weight of driving engine, but also will bear the counter-force that driving engine is exported to the car transmissions moment of torsion, the weight and the counter-force of having born very most driving engine before the automotive engine.The common engine front support device that adopts of goods carrying vehicle driving engine is at present: driving engine is bearing on the symmetrical engine front support body assembly with two cushion rubber bumpers respectively, and two engine front support body assemblies are cantilever beam structure.The employed high-horsepower diesel engine that is of heavy-duty truck, its weight is big, moment of torsion is big, and is higher to the requirement of engine front support.And along with the raising of heavy-duty truck driving engine reinforcing degree, particularly the use of exhaust turbocharging device is more and more general, and the weight and the moment of torsion of driving engine are increasing.Cause the chassis side rail distortion of at present used engine front support device installation site; The tenesmus of engine front support body assembly occurrence positions; The car transmissions correlation parameter changes, and causes driving system associated components noise and wearing and tearing to strengthen, and it is comparatively general that cushion rubber bumper damages phenomenon.Sometimes even the phenomenon that fracture takes place engine front support body assembly occurs.
Summary of the invention
The present invention proposes a kind of heavy-duty truck engine front support device, and it can overcome the problems referred to above.
This heavy-duty truck engine front support device provided by the invention; The girder that it is characterized in that a solid drawn pipe bending forming is arranged is as engine front support body assembly; The two ends of girder are welded with the connecting panel that a block plate is made respectively, are being symmetrically welded with left back plate and right back plate near connecting panel place, girder two ends; Weld a rectangle brace panel respectively on the top of left back plate and right back plate, the rectangle brace panel is connected as a single entity the connecting panel at left back plate and right back plate and two ends securely; In bottom, girder two ends, the triangle brace panel that welds block plate making respectively is to strengthen its Joint strenght; Engine front support body assembly places left and right longeron installed inside on vehicle frame.
Described left back plate and right back plate be symmetry mutually, and left back plate and right back plate lean on a face of girder to be made into circular arc to guarantee and the girder welding of fitting preferably.
Described girder is made with the solid drawn pipe that has than major diameter and certain wall thickness.
On left back plate and right back plate, a cushion rubber bumper is installed respectively with two bolts, flat gasket, spring washer and nut; The lifting driving engine; Driving engine two front support legs are placed on the cushion rubber bumper that is installed on left back plate and the right back plate; And the bolt hole that passes on the driving engine front support leg with special bolt is connected with cushion rubber bumper, to guarantee the bonded assembly reliability.Because the girder of engine front support body assembly places below engine sump tank front, the Pulley, can not interfere by occurrence positions with oil pan tray and other parts of driving engine.And its nadir can not influence the crossing ability of automobile far above the nadir of engine sump tank rear end.This engine front support body assembly has higher strength and stiffness, and the phenomenon of tenesmus of engine front support body assembly position and fracture no longer takes place, and has obtained very big lifting the service life of car opertion reliability and engine mounting associated components.And engine front support body assembly is equivalent to a cross member of frame on vehicle frame, can improve the strength and stiffness of this position of vehicle frame, improves the service life of vehicle frame, and this device can be widely used in heavy-duty truck.

The specific embodiment
Be elaborated below in conjunction with accompanying drawing.
Shown in Fig. 1～7, need mounted component driving engine 4 and this Unit Installation matrix vehicle frame left side longeron 1 to represent with vehicle frame right vertical beam 9 usefulness long and two-short dash linees, do transparence and handle.One of engine front support body assembly 2 usefulness have behind the larger-diameter solid drawn pipe bending forming as girder 25, and the two ends of girder are welded with the connecting panel 21 that a block plate is made respectively; Be symmetrically welded with left back plate 23 and the right back plate made from steel plate 26 near connecting panel place, girder two ends; On left back plate and right back plate top, weld the rectangle brace panel 22 that a block plate is made respectively, the connecting panel at left back plate and right back plate and two ends is connected as a single entity securely; The triangle brace panel 24 that welds block plate making in bottom, girder two ends respectively is to strengthen its Joint strenght.
Engine front support body assembly 2 is placed vehicle frame left side longeron 1 and vehicle frame right vertical beam 9 inboards, use eight M14 * 40 bolt 5, φ 14 flat gaskets 6, φ 12 spring washers 7 and M14 nut 8 that it is installed on the vehicle frame respectively.On preceding supporting mass assembly 2 left back plates and right back plate, a cushion rubber bumper 3 is installed respectively with two M8 * 25 bolt 11, φ 8 flat gaskets 12, φ 8 spring washers 13 and M8 nut 14; Lifting driving engine 4; 4 liang of front support legs of driving engine are placed on the cushion rubber bumper 3 that is installed on preceding supporting mass assembly 2 left back plates and the right back plate; And the bolt hole that passes on driving engine 4 front support legs with special bolt 10 is connected with cushion rubber bumper 3, to guarantee the bonded assembly reliability.Because the girder of engine front support body assembly 2 places below driving engine 4 oil pan tray fronts, the Pulley, can not interfere by occurrence positions with oil pan tray and driving engine 4 other parts.And its nadir can not influence the crossing ability of automobile far above the nadir of driving engine 4 oil pan tray rear ends.This engine front support body assembly 2 has higher strength and stiffness, and the phenomenon of tenesmus of engine front support body assembly 2 positions and fracture no longer takes place, and has obtained very big lifting the service life of car opertion reliability and engine mounting associated components.And engine front support body assembly 2 is equivalent to a cross member of frame on vehicle frame can improve the strength and stiffness of this position of vehicle frame, improves the service life of vehicle frame, and this device can be widely used in heavy-duty truck.
As shown in Figure 4, left back plate 23 and right back plate 26 leans on a face of girder 25 to be made into circular arc to guarantee and the girder welding of fitting preferably; Weld the rectangle brace panel 22 that a block plate is made on left back plate 23 and right back plate 26 tops respectively, left back plate 23 and right back plate 26 connecting panel with two ends is connected as a single entity securely.
As shown in Figure 5, connecting panel 21, rectangle brace panel 22, left back plate 23, girder 25 usefulness welding manners firmly connect.Be processed with eight bolt mounting holes on the connecting panel 21.
As shown in Figure 6, be welded with the right back plate made from steel plate 26 near girder 25 right-hand member connecting panels 21 places; Right back plate 26 leans on a face of girder 25 to be made into circular arc to guarantee and the girder welding of fitting preferably, is processed with two bolt mounting holes on the right back plate 26; Weld the rectangle brace panel 22 that a block plate is made on right back plate 26 tops, the connecting panel 21 of right back plate 26 with right-hand member is connected as a single entity securely, be processed with eight bolt mounting holes on the connecting panel 21.
As shown in Figure 7, girder 25 usefulness have than the solid drawn pipe of major diameter and certain wall thickness makes.
