Description

Fuel tank rear mounting bracket assembly

technical field

The invention relates to a mounting bracket, in particular to a mounting bracket assembly for installing motorcycle oil tanks and seat cushions.

Background technique

In the prior art, the fuel tank rear mounting bracket used to install the motorcycle fuel tank is a flat plate structure, and its left and right ends are directly welded to the left and right rear main pipes in the middle of the frame, so the strength of the middle of the frame is relatively low. On the other hand, the rear support point of the fuel tank and the front mounting support point of the seat cushion are respectively fixed by independent brackets, so the number of supports at the junction of the fuel tank and the seat cushion is relatively large, which increases the weight and manufacturing cost of the vehicle frame itself. Moreover, the cooperation between the fuel tank, the vehicle frame and the seat cushion is not tight, and there is a large joint between the three.

Therefore those skilled in the art devote themselves to developing a fuel tank rear mounting bracket assembly that can increase the strength of the middle part of the vehicle frame and make the vehicle frame, fuel tank and seat cushion fit closely.

Contents of the invention

In view of the above-mentioned defects in the prior art, the technical problem to be solved by the present invention is to provide a fuel tank rear mounting bracket assembly that can increase the strength of the middle part of the frame and make the frame, fuel tank and seat cushion fit closely.

To achieve the above object, the present invention provides a fuel tank rear mounting bracket assembly, including a fuel tank mounting plate; a first screw hole and a second screw hole are arranged on the fuel tank mounting plate; The back of the screw hole and the second screw hole are welded with a first nut and a second nut;

The left and right sides of the fuel tank mounting plate are folded down to form a left connecting plate and a right connecting plate that can be welded to the left and right rear main pipes of the vehicle frame respectively; the rear part of the fuel tank mounting plate is integrally provided with seat cushion inserts; The seat cushion insert is upturned relative to the fuel tank mounting plate.

In order to reduce weight and cost, a first weight reduction hole and a second weight reduction hole are arranged on the oil tank mounting plate.

In order to make the vehicle frame have higher strength with a lower weight, the first and second weight-reducing holes are arranged in front of the first and second screw holes.

In order to further increase the strength of the vehicle frame, the symmetry line of the first weight-reducing hole and the second weight-reducing hole coincides with the symmetry line of the first screw hole and the second screw hole.

In order to further increase the strength of the vehicle frame, both the left connecting plate and the right connecting plate are of airfoil structure and arranged symmetrically.

In order to facilitate the installation of the seat cushion, positioning holes are arranged on the insert piece of the seat cushion.

In order to further increase the strength of the vehicle frame, in the left-right direction, the center line of the positioning hole is located on the same plane as the symmetry line of the first screw hole and the second screw hole.

In order to further increase the strength of the vehicle frame, the front and rear flanges are respectively provided on the front and rear ends of the bracket assembly.

The beneficial effects of the present invention are: the present invention is not only the rear mounting support point of the fuel tank, but also the front mounting support point of the seat cushion, so the present invention reduces the number of mounting brackets structurally, and also reduces the weight and manufacturing of the vehicle frame itself. It also increases the strength of the middle part of the frame, and also makes the fuel tank, seat cushion, and frame have a close fit relationship, which has a positive effect on controlling the edge joints among the three.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

As shown in Figures 1 to 2, a fuel tank rear mounting bracket assembly includes a fuel tank mounting plate 1, and the fuel tank mounting plate 1 is provided with a first screw hole 2 and a second screw hole 3, and the fuel tank mounting plate 1 is on the first screw hole. The backs of the holes 2 and the second screw holes 3 are welded with a first nut 4 and a second nut 5 .

The left and right sides of the fuel tank mounting plate 1 are folded down to form a left connecting plate 6 and a right connecting plate 7 which can be welded with the left and right rear main pipes of the vehicle frame respectively. Both the left connecting plate 6 and the right connecting plate 7 are of airfoil structure and arranged symmetrically.

A first lightening hole 8 and a second lightening hole 9 are provided on the fuel tank mounting plate 1 .
