Frame assembly of all-terrain vehicle

An ATV and frame technology, which is applied in the field of ATVs, can solve the problems of increasing the height of the center of gravity of the whole vehicle, unreasonable arrangement of parts and components, and unreasonable distribution of the vehicle mass, so as to reduce the air intake stroke and air intake resistance. , The structure and mass distribution of the whole vehicle are reasonable, which is beneficial to the braking and control effect of the whole vehicle

Problems solved by technology

[0002] At present, the ATV frame basically adopts a frame structure, but considering the different usage conditions and processes, most of the space utilization rate is not high, and the layout of parts is not reasonable, which makes the quality distribution of the whole vehicle unreasonable and the cost is high
On the one hand, the traditional ATV frame is to install the rear rocker arm lugs 3 (including four pairs of mounting lugs on the front, rear, left, and right sides of the rear lower rocker arm and four pairs of mounting lugs on the front, rear, left, and right sides of the rear upper rocker arm), the main reducer The front and rear two pairs of mounting lugs 4 and the traction trailer 5 are designed separately and fixed to the frame separately, see figure 1 The disadvantages are: messy layout, many welding points, the position is not easy to stagger, resulting in a longer overall frame, separate positioning leads to complicated welding tooling, and increases the weight and cost of the frame, etc.
This arrangement also has the following defects at least: 1. When the fuel tank is arranged in the front, because it is at the top of the engine cylinder head, the temperature around the engine cylinder head is high, and the bottom of the fuel tank must be pasted with a corresponding anti-scald film to reduce the fuel tank temperature, which increases the cost and has Certain potential safety hazards; 2. When the fuel tank is arranged in front, the mass of the front axle will increase when it is fully loaded, making the mass distribution of the front and rear axles unreasonable. When braking, the mass of the front axle will increase even more, which will affect the braking performance of the vehicle and Maneuverability; 3. When the fuel tank is in the front, the height of the center of gravity of the vehicle is increased because the front part is relatively high, which is not conducive to driving maneuverability; 4. When the air filter is arranged in the rear, its relative position is low, and mud and water are easy to Enter, affect the wading depth of the vehicle

Embodiment Construction

[0013] The present invention will be further described below in conjunction with accompanying drawing.

[0014] see figure 2 , as can be seen from the figure, the ATV frame assembly of the present invention includes a left lower bottom pipe 6, a right lower bottom pipe 7, a left upper pipe 8, a right upper pipe 9, a left rear standpipe 10, a right rear standpipe 11, Left rear diagonal support pipe 12, right rear diagonal support pipe 13, front lower horizontal pipe 14, front middle horizontal pipe 15, left upper front pipe 16, right upper front pipe 17, front middle left pipe 18, front middle right pipe 19, bottom middle Cross pipe 20, traction trailer 5, air filter mounting lug 1, fuel tank mounting plate 21, rear upper rocker arm mounting lug 32, rear lower rocker arm mounting lug, main reducer front mounting lug 25, main reducer Install lug 28 afterward. These components above are also the structures that the existing beach car frame assembly has.

Abstract

The invention discloses a frame assembly of an all-terrain vehicle. The rear of a main reducing gear which is provided with a lug, and a rocker part which is provided with a lug and towing are combined into a whole through a bottom tube rear composition board, and the towing, a rear rocker and the main reducing gear are mounted, positioned and combined into a sheet metal component as possible; and simultaneously, an air filter provided with a lug is arranged on the front of a frame, and an oil tank mounting plate is arranged on the rear of the frame, so that an oil tank is positioned on the rear of the frame and the air filter is positioned on the front of the frame. The frame assembly has compact structure, optimized spacial arrangement, light weight and more reasonable mass distributionof a whole vehicle, improves welding manufacturability and reduces welding frock to reduce manufacturing cost, and well guarantees strength and rigidity of the whole vehicle through reinforcing members.

Description

technical field [0001] The invention relates to a beach car, in particular to a beach car frame structure. Background technique [0002] At present, the ATV frame basically adopts a frame structure, but considering the different usage conditions and processes, most of the space utilization rate is not high, and the layout of parts is not reasonable, which makes the quality distribution of the whole vehicle unreasonable and the cost is high . On the one hand, the traditional ATV frame is to install the rear rocker arm lugs 3 (including four pairs of mounting lugs on the front, rear, left, and right sides of the rear lower rocker arm and four pairs of mounting lugs on the front, rear, left, and right sides of the rear upper rocker arm), the main reducer The front and rear two pairs of mounting lugs 4 and the traction trailer 5 are designed separately and fixed to the frame separately, see figure 1 The disadvantages are: messy layout, many welding points, the position is not ...
