Problems solved by technology

[0019] However, the above connection methods have the following disadvantages: the rigid connection bracket or the elastic connection bracket tightly connects the subframe and the main frame, which increases the rigidity of the main frame and limits the necessary adjustment of the main frame to adapt to road conditions. The deformation of the main frame will increase the stress of the main frame and increase the possibility of damage to the main frame and sub-frame

Abstract

The invention relates to a double cross rotary shaft type floating connecting device for vehicle frame connection. The double cross rotary shaft type floating connecting device comprises floating connecting supports (9), a floating rotary support (10) and a rear rotary shaft structure (11). An auxiliary frame (8) is connected with a main frame (7) through the rear rotary shaft structure (11) and the floating rotary support (10) arranged in the middle of the auxiliary frame and the floating connecting supports (9) arranged at the head and the tail of the auxiliary frame, and does not directly contact with the main frame (7). On the premise of guaranteeing connecting strength and positioning, an auxiliary frame is allowed to deform and displace slightly relative to a main frame, deformation of the main frame in order to adapt to road conditions is free of limit, stress on the main frame is reduced, and probability of damage of the main frame is decreased. Meanwhile, vibration and impact transferred from the road surface are absorbed so as to protect upper mounting parts favorably. The double cross rotary shaft type floating connecting device is applicable to various types of vehicles, particularly off-road vehicles.

Description

technical field [0001] The invention relates to a mechanical connection device, in particular to a double horizontal pivot type floating connection device used for vehicle frame connection. Background technique [0002] In the design of special-purpose vehicles, in order to improve the bearing capacity of the main frame and avoid concentrated loads, and in order not to damage the structure of the main frame, sub-frame transitions are generally used. [0003] In addition to light vehicles, the strength and rigidity of the main girders of medium and heavy vehicles are sufficient, and the flexible design is often adopted in the structure, which is conducive to the release of the stress formed by the torsion and bending of the main girder during driving. When refitting a special vehicle, if the subframe is not necessary, the design without subframe can also be considered. [0004] The main deformation of the vehicle during driving is bending and twisting. The main frame bends a...
