Description
Technical field
The utility model relates to a kind of heavy truck power assembly gear box suspension fixed structures, belong to heavy truck neck
Domain.
Background technique
Heavy truck dynamic assembly suspension uses or 6 fixed forms at 5 points at present, and this form is matched to suspension system
Bring very big difficulty.Suspension system matching is unreasonable to cause transmission auxiliary support suspension system disabler, eventually lead to
The problems such as vibration isolation rate of power assembly is difficult to reach ideal requirement, power assembly damage of components.Therefore, existing 5 points or
6 fixed forms will lead to amount of parts, product development cost increases.
Summary of the invention
In view of the above-mentioned problems of the prior art, to provide a kind of heavy truck power assembly gearbox outstanding for the utility model
Fixed structure is set, so that powertrain mounting system matching is become simple, reduces the quantity of components.
To achieve the goals above, a kind of heavy truck power assembly gear box suspension fixed knot that the utility model uses
Structure, including engine and gearbox, the engine are equipped with two fixing points, further include that two be arranged on gearbox are hanged
Fixed point is set, two suspension fixed points in the two fixing points and gearbox on the engine, which are matched, is combined into four solid points of suspension
Determine structure.
As an improvement, described two suspension fixed points are arranged symmetrically in the two sides of power output end on gearbox.
As an improvement, linear distance of each suspension fixed point apart from plane where clutch end face is 0-725mm.
As an improvement, each distance of the suspension fixed point away from straight line where power intake and power output end is 0-
135mm。
As an improvement, the suspension fixed point uses horizontal fixed mechanism or vertical fixed mechanism.
As an improvement, the suspension fixed point is mounted on the pedestal of power output end two sides, the seat using horizontal symmetrical
It is provided with connecting hole and lightening hole on body, fastening bolt is installed in the connecting hole.
Compared with prior art, the utility model passes through two suspensions in the two fixing points and gearbox on engine
Fixed point can eliminate the anti-work of gearbox torque output using gearbox tail support with 4 fixed structures of suspension are combined into
Firmly to the influence of power assembly, the stability of power assembly is improved；Compared to traditional 5 points or 6 fixed forms, this reality
Reduce suspension fixed point with novel, substantially reduces power assembly decoupling difficulty, the vibration isolation efficiency of power assembly is improved, to mention
High vehicle NVH performance provides advantage, while the reduction of power assembly fixed point, reduces the quantity of components, improves
The production efficiency of vehicle.
Detailed description of the invention

Specific embodiment
To make the objectives, technical solutions and advantages of the present invention clearer, the utility model is carried out below
It is further described.However, it should be understood that specific embodiment described herein is only used to explain the utility model, not
For limiting the scope of the utility model.
Unless otherwise defined, all technical terms and scientific terms used herein and the skill for belonging to the utility model
The normally understood meaning of the technical staff in art field is identical, and terminology used in the description of the utility model herein is only
It is the purpose in order to describe specific embodiment, it is not intended that in limitation the utility model.
Improvement for convenience of explanation does following regulation: power intake 1 and power to the utility model (see attached drawing 1)
The origin of the line of output end 4 and the intersection point of clutch end face 2 (with flywheel shell of engine faying face) as coordinate system, to power
Output end 4 is X+, is upwards Z+, Y+ is determined by right-hand rule.
As shown in Figure 1, Figure 2 and Figure 3, a kind of heavy truck power assembly gear box suspension fixed structure, including engine
With gearbox 5, it further includes two suspension fixed points 3 being arranged on gearbox 5 that the engine, which is equipped with two fixing points,
Two suspension fixed points 3 in two fixing points and gearbox on the engine, which are matched, is combined into 4 fixed structures of suspension.
As the improvement of embodiment, described two suspension fixed points 3 are arranged symmetrically in power output end 4 on gearbox 5
Two sides.
As a further improvement, as shown in connection with fig. 1, each suspension fixed point 3 (flies apart from clutch end face 2 with engine
Wheel shell faying face) where linear distance in plane X-direction be 0-725mm.Each suspension fixed point 3 is away from 1 He of power intake
The distance of the Z-direction of 4 place straight line of power output end is 0-135mm.
As a further improvement, the suspension fixed point 3 uses horizontal fixed mechanism or vertical fixed mechanism.
When using horizontal fixed mechanism, the suspension fixed point 3 can be using shown in attached drawing 1, and horizontal symmetrical is mounted on
The pedestal of 4 two sides of power output end (in actual installation process, using the center of pedestal as suspension fixed point, calculates its practical peace
Fill distance), connecting hole 31 and lightening hole 32 are provided on the pedestal, and fastening bolt is installed in the connecting hole 31.
