The frame of the fixed tramcar is a frame structure composed of a pull plate in the middle, two longitudinal beams and two end bump seats which also act as cross beams& nbsp; The longitudinal beam of the frame is made of profiled channel steel with thick webs, and the head sockets at both ends of the frame are connected with the longitudinal beam through rivets. The contact block made of cast steel is provided with a capacity chain groove. The contact block (rubber spring) is installed in the contact block. When the tramcar collides, the contact block is used to absorb the impact energy and transfer the impact force from the contact block to the longitudinal beam of the frame. The axle clamp is an intermediate connecting part between the frame and the axle, which is fixed on the longitudinal beam of the frame through riveting. The upper end face of the frame longitudinal beam is connected with the trunk arc bottom plate by welding, and the lower end face is riveted with the axle clamp. Therefore, the upper end face of the frame longitudinal beam is under the pressure of the trunk and cargo load; When the lower end surface is in contact with the shaft clamp, it acts as the reaction force of the shaft clamp on the longitudinal beam.
