Abstract
The utility model proposes a kind of heavy-duty automotive speed changer support assembly, comprise leaf spring and at least one group of supporting bracket being arranged at leaf spring intermediate regulations leaf spring pulling force size, upper supporting bracket is connected with leaf spring by threaded fasteners, and lower support support is connected with change-speed box by threaded fasteners.Also comprise the anchor fitting being arranged at respectively and producing friction of rolling when leaf spring two ends make leaf spring length variations, anchor fitting is provided with hole and lower opening at least one group, is plugged in upper straight pin in hole and lower opening and lower straight pin and is fixed on the spring cotter of straight pin afterbody respectively; Leaf spring to be plugged between straight pin and lower straight pin and to contact with lower straight pin.The stressing conditions of clutch bell when change-speed box support assembly of the present utility model can effectively reduce driving; And during leaf spring generation deformation, pulling force size can be regulated by backing plate number, can play a supporting role to change-speed box, can alleviate again the moment produced with the bending of vehicle frame of beating because of change-speed box in driving.
Description
Technical field
The utility model belongs to car construction technical field, particularly a kind of heavy-duty automotive speed changer support assembly.
Background technology
The applying working condition of heavy motor vehicle is comparatively severe, and its car body is wider in addition, such that beating of change-speed box is comparatively large, change-speed box is stressed also comparatively large with clutch bell junction, easily occurs the phenomenons such as tie bolt is loosening, clutch bell cracking.Existing change-speed box supporting construction is developed mainly for road vehicle, and it is higher to be difficult to bear comparatively high pulling torque and requirement of significantly beating, fault rate, cannot meet the actual needs of bad working environment.
Utility model content
The utility model, in order to overcome the deficiency of above technology, provides a kind of heavy-duty automotive speed changer support assembly.
the technical solution of the utility model is as follows:
A kind of heavy-duty automotive speed changer support assembly, comprise leaf spring and be arranged at least one group of supporting bracket changing the stressed size of leaf spring in the middle of leaf spring, described leaf spring two ends are individually fixed in frame inside, and described supporting bracket is connected on change-speed box.
At least one backing plate that described supporting bracket comprises supporting bracket and lower support support and is arranged between supporting bracket and lower support support; Described upper supporting bracket is connected with leaf spring by threaded fasteners, and lower support support is connected with fast device by threaded fasteners.
Heavy-duty automotive speed changer support assembly of the present utility model, also comprise and be arranged at the anchor fitting that leaf spring two ends make to produce during leaf spring length variations cliding friction respectively, described anchor fitting is connected to frame inside by threaded fasteners.
Described anchor fitting is provided with hole and lower opening at least one group, is plugged in upper straight pin in hole and lower opening and lower straight pin and is fixed on the spring cotter of straight pin afterbody respectively; Described leaf spring to be plugged between straight pin and lower straight pin and to contact with lower straight pin.
the beneficial effects of the utility model are:
1. this change-speed box support assembly is connected with leaf spring and change-speed box respectively by upper and lower supporting bracket, backing plate is provided with between upper and lower supporting bracket, now change-speed box can slightly be raised, and the stressed of driving engine rear support slightly reduces, and can effectively reduce the stressing conditions of clutch bell during driving; And during leaf spring deformation, pulling force size can be regulated by backing plate number, can play a supporting role to change-speed box, the moment produced with the bending of vehicle frame of beating because of change-speed box in driving can be alleviated again.
2., when change-speed box bob, because leaf spring has rigidity, the power that can be produced by leaf spring deformation, slows down the jerk value of driving engine and change-speed box; When vehicle frame bending produces moment, the impact of moment on driving engine rear support and clutch bell can be reduced by the bending of leaf spring distortion.
3., by the rigidity of plate spring of assembly and the matching primitives of other supporting point positions, effectively can reduce the vibration frequency of assembly, thus protect change-speed box greatly.
4. the change-speed box support assembly of this utility model is easy to manufacture, install, and is applicable to producing in enormous quantities.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model heavy-duty automotive speed changer support assembly.
In figure, 1, leaf spring, 2, supporting bracket, 2-1, upper supporting bracket, 2-2, lower support support, 3, backing plate, 4, anchor fitting, 5, upper hole, 6, lower opening, 7, upper straight pin, 8, lower straight pin, 9, spring cotter.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described further.
As shown in Figure 1, a kind of heavy-duty automotive speed changer support assembly, comprise leaf spring 1 and at least one group of supporting bracket 2 being arranged at leaf spring intermediate regulations leaf spring pulling force size, supporting bracket 2 comprises supporting bracket 2-1 and lower support support 2-2, upper supporting bracket 2-1 is connected with leaf spring by threaded fasteners, and lower support support 2-2 is connected with change-speed box by threaded fasteners.Leaf spring two ends are respectively arranged with the anchor fitting 4 producing cliding friction when making leaf spring length variations, anchor fitting 4 is connected to frame inside by threaded fasteners, the lower opening 6 that lower straight pin 8 inserts anchor fitting 4 is interior and fixing by spring cotter 9, leaf spring is put on lower straight pin 8, then is fixed by spring cotter 9 in the upper hole 5 of upper straight pin 7 being inserted anchor fitting 4.Now go up between supporting bracket 2-1 and lower support support 2-2 and have certain interval, backing plate 3 is filled between upper supporting bracket 2-1 and lower support support 2-2 by pulling force as required, and urgent with attaching parts.Now change-speed box can slightly be raised, and the stressed of driving engine rear support slightly reduces, and can effectively reduce the stressing conditions of clutch bell during driving; This assembly can be played a supporting role to change-speed box, can alleviate again the moment produced with the bending of vehicle frame of beating because of change-speed box in driving.When vehicle frame bending produces moment, the impact of moment on driving engine rear support and clutch bell can be reduced by the bending of leaf spring distortion.
