Abstract
The utility model discloses an auxiliary supporting device of a flexible transmission case, which comprises a flexible upper supporting beam fixed on a transmission case casing through an angle bracket. Two ends of the flexible upper supporting beam are movably connected in a transmission case bracket assembly. The auxiliary supporting device of the flexible transmission case adopts an optimal design of an auxiliary supporting device of a common transmission case, has the characteristic of good shock absorption effect, ensures that the transmission case can not be violently shocked when vehicle body is suddenly strained, and guarantees the operation stability of the transmission case. In addition, the self weight of the device is reduced, so that material consumption is saved, and the device meets the requirement on light weight.
Description
Technical field
The utility model belongs to the technical field of heavy-duty car car load optimal design.
Background technique
Existing heavy duty automobile gear box secondary support means is the structural type that rigid beam adds rubber pad basically, therefore deformation is less in the vibrations of power assembly, damping effect is relatively poor, and serious may causing when vibrations and play are big causes the gearbox of rod-type manipulation out of supply; Rubber pad aging and flow and can cause the sinking of gearbox, and then make the elastic element distortion of back suspension device of engine and flow, and then make the attitude of whole power assembly and the bigger change of generation of design in advance.
Summary of the invention
The utility model purpose provides a kind of flexible gearbox secondary support means, to overcome the shortcoming that common auxiliary support apparatus is out of shape little damping effect difference.
Specifically, a kind of flexible gearbox secondary support means, it has by the angle support and is fixed on flexible upper support beam on the gear box casing, and flexible upper support beam two ends are movably connected in the gearbox bracket assembly.
Described flexible upper support beam is the leaf spring structure.
The flexible gearbox secondary support means of the utility model is the optimal design to common gearbox secondary support means, and this bearing device has following advantage with respect to common secondary support means:
1. good damping effect.What strutbeam adopted on the gearbox flexibility is the leaf spring structure, deformation effect is comparatively obvious in the vibrations of power assembly, thereby overcome the shortcoming that common auxiliary support apparatus is out of shape little damping effect difference, make gearbox when work, can bigger play not take place simultaneously, guaranteed the working stability of gearbox because of vehicle body is stressed suddenly.
2. own wt reduces.This bearing device adopts the thin plate spring structure, and the weight of self is reduced, and has saved materials consumption, meets lightweight requirements.
3. simple in structure, economical and practical.Consider Economy and practicability, the whole flexible support beam that adopts of this bearing device is connected with the gearbox bracket assembly, and is not only simple in structure, and economical and practical.
The utility model is to aim at the heavy duty automobile gear box supplemental support and the optimal design of carrying out, and has filled up the technological deficiency in this field of gearbox supplemental support.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
