Abstract

The utility model discloses an auxiliary bearing device for an engine of a medium-size truck. The auxiliary bearing device for the engine of the medium-size truck is characterized in that: after the engine and a transmission are assembled integrally, a bearing crossbeam is connected with the top of the transmission at the back end of the engine; two ends of the supporting crossbeam are respectively cushioned by rubber cushioning pads, and then are connected with a support body which is punched and formed by a steel plate and then welded; and as the cushioning pads have better elasticity, not only can the vibration of the engine during working be eased, but also the over-location problem of the auxiliary bearing device for the engine can be solved. The medium-size truck after being additionally provided with the auxiliary bearing device for the engine can greatly lighten the loads born by a front bearing device and a back bearing device of the engine, and greatly improve the using reliability of the truck as well as the service lives of relevant bearing parts of the engine.

Description

A kind of moderate duty truck driving engine secondary support means
Technical field
The utility model relates to bearing device for automobile engine, particularly a kind of moderate duty truck driving engine secondary support means.
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 support pattern of moderate duty truck driving engine is divided into usually at present: 1, engine front support device by the rubber cushion rubber bumper, is bearing in vehicle frame left and right longeron inboard with front of the engine on left and right both sides, engine cylinder-body bottom.2, bearing set behind the driving engine is bearing in vehicle frame left and right longeron inboard with the driving engine rear end by the rubber cushion rubber bumper on the left and right both sides of flywheel shell of engine.
Along with the diesel oil degree of moderate duty truck driving engine is more and more higher, and reinforcing degree is also more and more higher, and 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.And the parameter of used change-speed box is more and more advanced, and weight is also increasing.Cause the left and right longeron distortion of vehicle frame of the at present used forward and backward bearing set of driving engine installation site, the tenesmus of the forward and backward supporting mass assembly of driving engine occurrence positions, the car transmissions correlation parameter changes, cause driving system associated components noise and wearing and tearing to strengthen, it is comparatively general that the forward and backward bearing set cushion rubber bumper of driving engine damages phenomenon.Sometimes even the phenomenon that fracture takes place the forward and backward supporting mass assembly of driving engine occurs.
Summary of the invention
The utility model proposes a kind of moderate duty truck driving engine secondary support means, it can address the above problem.
This a kind of moderate duty truck driving engine secondary support means that the utility model provides, it is characterized in that driving engine and change-speed box are assembled into one behind the part, change-speed box top in the driving engine rear end connects a bearing cross beam, and the bearing cross beam two ends are connected the left and right longeron inboard of vehicle frame respectively by stake body.
The change-speed box top of described driving engine rear end is processed with two tapped bore, and driving engine and change-speed box are assembled into one behind the part, by being installed in the bolt in these two tapped bore, change-speed box are connected the bearing cross beam bottom that forms with assembly welding after the steel plate drawing.The bearing cross beam two ends are connected with on the stake body that assembly welding forms after the steel plate drawing after filling up cushion rubber bumper respectively, and each stake body is connected the left and right longeron of vehicle frame inboard with bolt and self lock nut respectively.
Because cushion compound is lined with elasticity preferably, the vibration in the time of not only can slowing down engine operation, and can solve the mistake orientation problem of driving engine secondary support means.After moderate duty truck installs this a kind of driving engine secondary support means additional, alleviate the load that the forward and backward bearing set of driving engine bears greatly, obtained very big lifting the service life of car opertion reliability and engine mounting associated components.
Description of drawings
Fig. 1 is an overall structure front view of the present utility model.
Fig. 2 is that the K among Fig. 1 is the birds-eye view of overall structure to view.
Fig. 3 is that the A-A cutaway view among Fig. 1 is stake body and bearing cross beam connection structure scheme drawing.
Each label is in Fig. 1~3: 1-vehicle frame, 2-stake body, 3-bearing cross beam, 4-change-speed box, 5-bolt, 6-cushion rubber bumper, 7-self lock nut, 8-first bolt, 9-second bolt, 10-flat gasket, 11-nut.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
As shown in Figure 1, the change-speed box 4 that need install and the vehicle frame 1 usefulness long and two-short dash line that this device is installed are represented, do transparence and handle.Change-speed box 4 tops of driving engine rear end are processed with two tapped bore, and driving engine and change-speed box are assembled into one behind the part, by being installed in the bolt 5 in these two tapped bore, change-speed box are connected bearing cross beam 3 bottoms that form with assembly welding after the steel plate drawing.Bearing cross beam 3 two ends are connected on the stake body 2 that forms with assembly welding after the steel plate drawing after filling up two cushion rubber bumpers 6 respectively, and the two stands body is connected the left and right longeron inboard of vehicle frame respectively with first bolt 8 and self lock nut 7.Cushion rubber bumper 6 has elasticity preferably, the vibration in the time of not only can slowing down engine operation, and can solve the mistake orientation problem of driving engine secondary support means.After moderate duty truck installs this a kind of driving engine secondary support means additional, alleviate the load that the forward and backward bearing set of driving engine bears greatly, obtained very big lifting the service life of car opertion reliability and engine mounting associated components.
As shown in Figure 2, bearing cross beam 3 left and right two ends are bearing in respectively on the stake body 2 at two ends, and two bolts 5 of change-speed box 4 usefulness are connected bearing cross beam 3 bottoms.
As shown in Figure 3, after bearing cross beam 3 pads are gone up cushion rubber bumper 6, be connected on the stake body 2, behind the fastening nut, refill a same nut, prevent nut loosening, to guarantee the bonded assembly reliability with second bolt 9, flat gasket 10 and nut 11.
