Abstract
The invention provides an improved protection support of an automobile transmission shaft. The improved protection support comprises a support lower piece, a left support upper piece and a right support upper piece, wherein the support lower piece is a U-shaped support, an arc shape is formed between the left support upper piece and the support lower piece, the right support upper piece is perpendicular to the support lower piece, a first bolt hole and a second bolt hole are formed in the right support upper piece and connected with an automobile body through bolts, the top end of the left support upper piece and the right support upper piece are located at the same horizontal height, and a rubber mat having the buffer function is arranged above the support lower piece. According to the protection support, the split assembly structure and the installing hole positions of the support lower piece, the left support upper piece and the right support upper piece are made reasonable, the rubber mat is installed and can protect the transmission shaft, the protection support has the advantages of being simple in structure and convenient to install, and safety performance of a whole automobile is guaranteed.
Description
Technical field
The invention belongs to auto parts and components apparatus field, especially relate to a kind of improved propeller-shaft protective cradle.
Background technology
Transmission shaft protective cradle is in the time that car load turns round; after drive shafts fracture, do not cause injury to other parts of rotation because of transmission shaft and land after car load is supported to the parts that design; light bus is because chassis part is many; space is less, and the design and installation of transmission shaft fender bracket have certain difficulty.
At present, the drive shaft protection bracket being equipped with on existing automobile adopts U-shaped bracket, because the attachment face of U-shaped bracket is vertical with U-shaped plane, therefore in the time being connected with cross member of frame, need to increase a transition bracket.There is defect in this drive shaft protection bracket, when cross member of frame lower aerofoil is arc surface, need be mounted on the cross member of frame outside of belly by transition bracket; complex structure; assembling is inconvenient, and cost is high, needs a kind of propeller-shaft protective cradle of simple in structure, easy to assembly, good buffer effect.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of improved propeller-shaft protective cradle, and this supporting structure is simple, reasonable in design, transmission shaft is played a very good protection.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of improved propeller-shaft protective cradle, comprise part under support, part on part and right support on left frame, under described support, part is U-shaped frame, curved between part under part and described support on described left socle, on described left socle, part is provided with the first mounting hole, under described support, part one side is provided with the second mounting hole, described the first mounting hole is connected with described the second mounting hole by thru-bolt, on described right support, part is vertical with part under described support, on described right support, part is provided with the first bolt hole, the second bolt hole, described the first bolt hole, described the second bolt hole is connected with auto body by bolt, on described left socle on part top and described right support part in same level height, under described support, part top is provided with the rubber pad that plays buffer action.
On described left socle, under part and described support, the radian scope between part is 15 °-25 °.
Under described support, part is connected by adhesion with described rubber pad.
On described left socle, on part, described right support, under part and described support, part is metal material integrated formed structure.
The present invention is by one package structual and the mounting hole site of part on part, left and right support under reasonable support, and installation rubber pad, and transmission shaft is played a protective role, and has advantage simple in structure, easy for installation, ensures whole vehicle safety performance.

Detailed description of the invention
As shown in Figure 1, the invention provides a kind of improved propeller-shaft protective cradle, comprise part 1 under support, part 3 on part 2 and right support on left frame, under support, part 1 is U-shaped frame, curved between part 1 under part 2 and support on left socle, on left socle, part 2 is provided with the first mounting hole 4, under described support, part one side is provided with the second mounting hole 5, the first mounting hole 4 is connected with the second mounting hole 5 by thru-bolt, on right support, part 3 is vertical with part under support 1, on right support, part 3 is provided with the first bolt hole 6, the second bolt hole 7, the first bolt hole 6, the second bolt hole 7 is connected with auto body by bolt, on left socle on part 2 tops and right support part 3 in same level height, under support, part 1 top is provided with the rubber pad 8 that plays buffer action, part 2 on left socle, on right support part 3 respectively with support under part 1 be metal material integrated formed structure.
Embodiment: transmission shaft protective cradle comprises under support on part 1, left frame part 3 on part 2 and right support; on left socle, under part 2 and support, the radian scope between part 1 is 20 °; on left socle on part 2, right support part 3 respectively with support under part 1 be made into integration by stainless steel; under support, part 1 is connected with rubber pad 8 by adhesion, the propeller-shaft of installing is played to the effect of buffering decompression.
When use; first transmission shaft protective cradle is installed on vehicle body mounting hole by the first bolt hole 6, the second bolt hole 7; transmission shaft is installed again; finally two-way bolt is arranged in the second mounting hole 5 of part 1 under the first mounting hole 4 of part 2 on left socle and support; realize the protection to transmission shaft, under support, the rubber pad 8 of part top plays the effect of fine buffer protection to transmission shaft.
Above one embodiment of the present of invention are had been described in detail, but described content is only preferred embodiment of the present invention, can not be considered to for limiting practical range of the present invention.All equalization variation and improvement etc. of doing according to the present patent application scope, within all should still belonging to patent covering scope of the present invention.
