Problems solved by technology

[0003] The above-mentioned connection method has the following disadvantages: when the vehicle is running, it is easy to cause deformation and damage to the sub-frame or the frame when the frame is twisted
When driving on rough roads, due to the large impact load, it is easy to damage the bodywork, and the noise caused by the impact is relatively large
When the car is running off-road, the frame and the upper body are twisted and deformed a lot, and the places where the stress is concentrated are easily damaged, and the off-road safety is poor

Embodiment Construction

[0017] Such as figure 1 , figure 2 As shown, the full-floating connection bracket 13 of the present invention is in the form of a triplet, and is installed between the main frame 11 and the sub-frame 12 of the refitted vehicle. There are four full-floating connection brackets 13, which are symmetrically installed in front, back, left, and right on the refitted vehicle.

[0018] Such as image 3 , Figure 4 , Figure 5 As shown, the present invention consists of an upper connecting plate 1, a high-strength bolt 2, a composite elastic element 3, a guiding anti-shear I set 4, a guiding anti-shearing II set 5, a rectangular section spring 6, a bearing washer 7, a nut 8, and a lower connecting plate 9 form a joint structure of full floating connection bracket 13. Among them, guide anti-shear I set 4 and guide anti-shear II set 5 are made of 30# steel. The upper connecting plate 1 and the lower connecting plate 9 are made of high-strength alloy steel. The fully floating conn...

Abstract

A full floating connecting support is welded on an auxiliary frame. Guiding anti-shear sleeves I are arranged in connecting holes of an upper connecting plate, and flanges of the guiding anti-shear sleeves I are lapped on the upper connecting plate. High strength bolts are disposed in holes of the guiding anti-shear sleeves I, and guiding anti-shear sleeves II are sleeved on outsides of the guiding anti-shear sleeves I. The guiding anti-shear sleeves II are disposed in connecting holes of a lower connecting plate, and flanges of the guiding anti-shear sleeves II are lapped on the lower connecting plate. Lower portions of the guiding anti-shear sleeves II are in sleeve joint with springs with rectangular sections, and the springs with the rectangular sections are connected to lower ends ofthe high strength bolts by load-bearing gaskets and nuts. A composite elastic element is disposed between the upper connecting plate and the lower connecting plate. The high strength bolts, the guiding anti-shear sleeves I and the guiding anti-shear sleeves II jointly penetrate through connecting holes of the composite elastic element. The lower connecting plate is connected with a main frame by bolts. Various impact loads are effectively reduced by the aid of the full floating connecting support. The full floating connecting support can move in directions with six degrees of freedom in a setmanner while connecting strength is guaranteed, structural flexibility of a vehicle is improved, damage of a carriage is avoided, and impact noise is reduced. The full floating connecting support is applicable to various vehicles, in particular to off-road vehicles.

Description

technical field [0001] The invention relates to a connection accessory between a vehicle bodywork and a main frame, in particular to a fully floating connection bracket for an off-road vehicle bodywork and a main frame. Background technique [0002] At present, the special vehicle manufacturing industry is developing rapidly, with many types and large quantities. Most of them are modified on the basis of the second-class chassis, and the connecting bracket is used to connect the sub-frame and the main beam of the chassis, and then install the top. [0003] The above-mentioned connection method has the following disadvantages: when the vehicle is running, the sub-frame or the frame is easily deformed and damaged when the frame is twisted. When driving on rough roads, due to the large impact load, it is easy to damage the bodywork, and at the same time, the noise caused by the impact is relatively large. When the car is running off-road, the frame and the upper body are twis...
