The arrangement and the connection strength have an important effect on safety. Meanwhile, a plurality of accessories such as an engine, a gearbox, air inlet and exhaust, suspension and the like are arranged between the cab and the frame, the position arrangement of the lifting device is influenced by space limitation, and the connection arrangement of the lifting device and the floor is also influenced by space and strength, so that the arrangement and the connection scheme of the floor and the lifting device have important significance and influence on the space arrangement of the chassis and the structural strength of the cab. The lifting device with high strength, small occupied space and flexible arrangement and the connecting structure become new design requirements of the cab.

At present, a widely-used commercial vehicle lifting device is arranged and connected with a scheme mainly comprising: 1. the lifting rod is positioned right below the floor longitudinal beam and is directly connected with the floor longitudinal beam through the lifting bracket, and the strength is borne by the floor longitudinal beam as shown in fig. 5; 2. the lifting rod is positioned right below the floor and connected with the cross beam through the lifting bracket, and the strength is transmitted and born by the cross beam to the floor and the longitudinal beam, as shown in fig. 6.

The first solution, namely the arrangement and connection solution as shown in fig. 5, has a lifting rod located directly below the floor stringers, and is directly connected to the stringers by lifting brackets, the strength of which is borne by the stringers. The longitudinal beam is used as one of the floor assembly and the bearing component of the cab, and has the characteristic of high structural strength, so that the lifting mechanism has lower requirement on the strength reinforcement of the cab, and no additional reinforcing structure is required; however, the arrangement position of the lifting rod is required to be high, and the arrangement of the lifting rod is difficult to compete under the floor longitudinal beam for complex chassis arrangement.

The second solution, namely the arrangement and connection solution shown in fig. 6, is that the lifting rod is located right under the floor and is in a completely offset position with respect to the longitudinal beams, and in this case, in order to ensure structural strength, the floor is reinforced by the cross beams between the lifting rod and the floor through the lifting brackets. The lifting support is connected with the cross beam, and the cross beam is connected with the floor and the longitudinal beam for stress dispersion. The arrangement scheme has the advantages of large structural weight and more occupied space. But the arrangement position of the lifting lever is flexible.

Therefore, aiming at the current situation of the two schemes, the development of the lifting arrangement connecting device of the commercial vehicle with small occupied space, strong flexibility and high structural strength is an urgent problem to be solved.
