Abstract

The invention discloses an articulated chassis of low-speed and heavy-duty road-rail dual-purpose traction equipment. The frame adopts an articulated structure, the track drive and the road drive adopt the same drive form to facilitate maintenance, the track wheel adopts a buffer shock-absorbing structure, the road drive wheel adopts solid rubber tires, and the road driving wheel is designed as a lifting structure, which is realized by the lifting swing arm The function is driven by a hydraulic cylinder. When it is raised, it is supported by the rail wheel and runs on the track. After it is lowered, it is supported by the road wheel and travels on the road. twist.

Description

technical field [0001] The invention belongs to the field of special walking machinery, and in particular relates to an articulated chassis of low-speed and heavy-duty road-rail dual-purpose traction equipment. Background technique [0002] The articulated frame is widely used in construction machinery and off-highway vehicles, and has the characteristics of flexible steering and small turning diameter. At present, in the road-rail dual-purpose transport vehicles, the integral frame is used. For the environment with narrow space, the turning radius is often difficult to meet the requirements. Because the track generally does not need a special steering mechanism, especially for small track equipment . There is no steering angle between the track wheels and the car body, and the wheels can be directly connected to the frame without a steering mechanism. Contents of the invention [0003] Aiming at at least one of the above defects or improvement needs in the prior art, th...
