Description

The transmission shaft intermediate supporting device
Technical field
The utility model belongs to the heavy motor vehicle production technical field, is specifically related to a kind of transmission shaft intermediate supporting device.
Background technology
Along with the raising of road quality, the continuous extension of express highway mileage, in addition the continual renovation of automotive engine is regenerated, and the moving velocity of automobile is more and more faster.The hidden danger of covering some mechanism arrangement under the low speed driving operating mode for a long time also little by little exposes to the open air out.On the long wheelbase automobile; In order to improve critical speed of drive shaft, avoid resonating and considering the needs in the car load general layout, often with the transmission shaft segmentation; At this moment just need add intermediate supporting device; This intermediate supporting device is installed on the cross member of frame usually, with the compensation transmission shafts to the installation error of angle direction, and play and the vehicle frame etc. of driving engine are out of shape caused displacement in the vehicle ' process.
The general intermediate supporting device that adopts structure illustrated in figures 1 and 2 of heavy serial commercial vehicle/comm..vehicle; The terminal pad 2, support connecting plate 3 and the bearing 4 that comprise rubber axis bearing 1, U-shaped; Bearing 4 is located in the rubber axis bearing 1; Support connecting plate 3 is firm with the both ends riveting of terminal pad 2, and rubber axis bearing 1 cylindrical is bonding and riveting is firm in the space that terminal pad 2 and support connecting plate 3 surround.The above structure of intermediate supporting device has following defective in concrete installation and use:
The first, there is installation error in assembly.Support connecting plate 3 lock onto on the cross member of frame, and the volume of vehicle frame own is bigger, and is mostly that soldering group is fit; The binding bolt connecting bore of support connecting plate 3 does not have setting range; Be difficult to guarantee that rubber axis bearing 1 is in free state, when quiescence, rubber axis bearing 1 is born tensile stress and compression effort; Be difficult to normally bring into play the cushioning effect of rubber, directly cause rubber axis bearing 1 early deformation, tear.
The second, there is defective in this body structure of intermediate supporting device.Transmission shaft is connected cooperation with bearing 4 inner rings, together rotatablely moves with transmission shaft, and transmission shaft itself produces certain rotor inertia; Upside bears tensile stress always; The equal compression chord of downside, according to the performance limitations of rubber own, and terminal pad 2 is not less than rubber matrix intensity with the firm intensity of the bonding and riveting of rubber axis bearing 1; Be easy to cause rubber axis bearing 1 upside to tear like this, vehicle performance is affected greatly.
The utility model content
The utility model is in order to solve weak point of the prior art, provides a kind of and can reduce installation error, prolonged the rubber axis bearing transmission shaft intermediate supporting device in service life.
For solving the problems of the technologies described above; The utility model adopts following technical scheme: the transmission shaft intermediate supporting device; The terminal pad 2, support connecting plate 3 and the bearing 4 that comprise rubber axis bearing 1, U-shaped; Bearing 4 is located in the rubber axis bearing 1, is provided with auxiliary connecting panel 5 between the two ends of the terminal pad 2 of said U-shaped, and rubber axis bearing 1 outer ring is located in the space that surrounds between terminal pad 2 and the auxiliary connecting panel 5; Support connecting plate 3 two ends are respectively equipped with a hanger 6 downwards, and hanger 6, terminal pad 2 and auxiliary connecting panel 5 removably connect through binding bolt 7.
Said support connecting plate 3 both sides are respectively equipped with a prolate connecting bore 8.
Adopt technique scheme, the rubber axis bearing does not contact with support connecting plate, takes into full account the performance holding capacity of rubber situation own, avoids the rubber axis bearing to bear tensile stress, at vehicle during owing to the rough and uneven in surface vibration in road surface, and can play position-limiting action.The prolate connecting bore is set on the support connecting plate, can makes support connecting plate, help like this to wait when mounted and reduce assembly stress and error with respect to the auxiliary connecting panel certain angle that deflects.
The utility model is reasonable in design, simple in structure, through limited installation testing, can satisfy the vehicle stabilization operation, and protection rubber axis bearing is not damaged and increases the service life, and is respond well, practical, is easy to apply.

The specific embodiment
Like Fig. 3, Fig. 4 and shown in Figure 5; The transmission shaft intermediate supporting device of the utility model; The terminal pad 2, support connecting plate 3 and the bearing 4 that comprise rubber axis bearing 1, U-shaped; Bearing 4 is located in the rubber axis bearing 1, is provided with inverted U-shaped auxiliary connecting panel 5 between the two ends of the terminal pad 2 of U-shaped, and rubber axis bearing 1 outer ring is located in the space that surrounds between terminal pad 2 and the auxiliary connecting panel 5; Support connecting plate 3 two ends are respectively equipped with a hanger 6 downwards, and hanger 6, terminal pad 2 and auxiliary connecting panel 5 ecto-entad successively removably connect through binding bolt 7.Support connecting plate 3 both sides are respectively equipped with a prolate connecting bore 8.
During installation; Should at first bearing 4 inner rings be installed on the transmission shaft, use bolt support connecting plate 3 to be contained on the cross member of frame rotating drive shaft assembly through two prolate connecting bores 8; Make rubber axis bearing 1 vertical and be in free state, lock binding bolt 7 then with respect to drive shaft axis.Can be good at avoiding the accumulated error of vehicle frame welding to cause between two prolate connecting bores 8 and driving engine (or tor-con) output flange error like this apart from error and setting angle; Can make support connecting plate 3 with respect to auxiliary connecting panel 5 certain angle (as shown in Figure 4) that deflects, help like this to wait when mounted and reduce assembly stress and error.Thereby satisfy the vehicle stabilization operation, protection rubber axis bearing 1 is not damaged and increases the service life.
