Description

Technical Field

[0001] This utility model belongs to the field of bus manufacturing technology, specifically relating to a flexible shaft fixing bracket for gear shifting in a 12-meter fully load-bearing bus gearbox. Background Technology

[0002] Existing gearbox selector shift cable fixing bracket structure, such as Figure 1 As shown, the main components are an L-shaped bracket base plate, reinforcing ribs, a left-side fixing component, and a left-side reinforcing rib. These components are manufactured by cutting, bending, and drilling according to the diagram. After processing, these four parts are welded together into a single unit using CO2 gas shielded welding. The L-shaped bracket base plate in this design has an excessively large lateral span, which can easily cause significant deformation of the gear shift cable fixed to its side during operation. This can prevent the vehicle from shifting gears properly, ultimately rendering the vehicle undrivable. Utility Model Content

[0003] The purpose of this invention is to provide a flexible shaft fixing bracket for gear shifting in a 12-meter fully load-bearing bus gearbox, which solves the problem that existing structures are prone to deformation, causing vehicles to be unable to shift gears normally.

[0004] The technical solution adopted by this utility model is a flexible shaft fixing bracket for gear shifting of a 12-meter fully load-bearing bus gearbox, including a right L-shaped fixing seat, the left end of which is connected to a left L-shaped fixing seat, a triangular reinforcing rib between the top and bottom of the left L-shaped fixing seat, a non-circular reinforcing rib perpendicularly between the right end of the left L-shaped fixing seat and the right L-shaped fixing seat, and a front reinforcing plate between the front right end of the right L-shaped fixing seat and the non-circular reinforcing rib, with multiple mounting holes opened along the length direction on the front reinforcing plate.

[0005] Preferably, the mounting holes are elliptical, and the three mounting holes are evenly spaced.

[0006] Preferably, the top surface of the aforementioned front reinforcing plate gradually slopes upward from left to right, with the top of the right end located in the middle of the right side facade of the right L-shaped fixing seat, and the height of the left end being one-third of the right side facade of the right L-shaped fixing seat.

[0007] Preferably, the front end of the aforementioned irregular reinforcing rib is flush with the front reinforcing plate, and the height of the front reinforcing plate is the same as that of the front reinforcing plate, and the two are welded together.

[0008] Compared with the prior art, the beneficial effect of this utility model is that by setting a front reinforcing plate at the front end of the irregular reinforcing rib and the right L-shaped fixing seat, and opening mounting holes on the front reinforcing plate, the distance between the right side of the right L-shaped fixing seat and the middle mounting hole is sufficiently and reliably reduced, ensuring that the gear shift cable fixed on its side will not deform during operation, and also ensuring that the vehicle can smoothly perform gear shifting operations during normal driving. Attached Figure Description

[0009] Figure 1 Select a shift cable shaft mounting bracket structure for the existing gearbox;

[0010] Figure 2 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0011] The present invention will be further explained below with reference to the accompanying drawings to enable those skilled in the art to better understand it.

[0012] Example 1

[0013] like Figure 2 As shown, the flexible shaft fixing bracket for the gear shifting of a 12-meter fully load-bearing bus gearbox includes a right L-shaped fixing seat 1. The left end of the right L-shaped fixing seat 1 is connected to the left L-shaped fixing seat 4. A triangular reinforcing rib 5 is provided between the top and bottom ends of the left L-shaped fixing seat 4. A non-circular reinforcing rib 3 is provided vertically between the right end of the left L-shaped fixing seat 4 and the right L-shaped fixing seat 1. A front reinforcing plate 2 is provided between the right side of the right L-shaped fixing seat 1 and the non-circular reinforcing rib 3. Three evenly spaced mounting holes are opened on the front reinforcing plate 2 along the length direction. The mounting holes are elliptical.

[0014] The top surface of the front reinforcing plate 2 gradually slopes upward from left to right. The top right end of the front reinforcing plate 2 is located in the middle of the right side facade of the right L-shaped fixing seat 1, and the height of the left end is one-third of the right side facade of the right L-shaped fixing seat. This structure helps the front reinforcing plate 2 to provide structural support for the right L-shaped fixing seat 1, preventing the right L-shaped fixing seat 1 from deforming due to excessive pressure on the side shift cable during operation.

[0015] Furthermore, the front end of the irregular reinforcing rib 3 is flush with the front reinforcing plate 2, and the height of this end face is the same as that of the front reinforcing plate 2. The two are welded together. The front reinforcing plate 2 and the irregular reinforcing rib 3 form a complete support structure, which helps to distribute the pressure on the right L-shaped fixing seat 1 and the left L-shaped fixing seat, and avoids concentrated stress deformation.

[0016] The overall design of this utility model consists of an L-shaped fixing base 1 on the right side made of 8mm thick steel plate, a front reinforcing plate 2 made of 8mm thick steel plate, an irregular reinforcing rib 3 made of 8mm thick steel plate, an L-shaped fixing base 4 on the left side made of 8mm thick steel plate, and a triangular reinforcing rib 5 made of 8mm thick steel plate. These components are manufactured by cutting, bending, and drilling according to the structure shown in the figure. After the above five components are manufactured, they are welded together using carbon dioxide gas shielded welding according to the overall dimensions and other requirements of the design to form a gearbox shifting flexible shaft fixing bracket.

[0017] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from its design spirit and principles should fall within the protection scope defined by the claims of the present invention.
