Abstract
The invention discloses a welding bogie. The welding bogie comprises wheel pair assemblies, a framework assembly, shaft box hanging systems and braking devices. The framework assembly is of an H-shaped structure formed by a beam and side beams in an inserting connection and installing and welding mode. The framework assembly is located on the two wheel pair assemblies through the shaft box hanging systems. Each braking device is an integrated foundation braking device. The integrated foundation braking devices are hung on the framework assembly through hanging rod assemblies. The framework assembly is formed by the beam and the side beams in the inserting connection and installing and welding mode. The requirement for strength is met, and the structure is simple. Linuoer shock absorber structures are adopted for the shaft box hanging systems, and therefore linear running stability is guaranteed, and the welding bogie adapts to curve passing capacity. Rubber springs are adopted for the shaft box hanging systems, and therefore the shaft box hanging systems have rigidity and damping in the vertical direction, the transverse direction and the longitudinal direction, the structure is simple, and maintaining is easy. The braking devices are the integrated foundation braking devices, and the best braking characteristic can be transmitted through the design principle of a parallelogram.

Described Axie box support device comprises axle box composition, and described axle box composition both sides are provided with rubber spring, and have rigidity and the damping in vertical, horizontal and vertical three directions, structure is simple, is easy to safeguard.
Beneficial effect of the present invention is:
1. framework composition is formed by crossbeam and curb girder grafting assembly welding, and compared with three large frame bogie trucks, structure is simple, and environmental pollution is little, meets requirement of strength.
2. Axie box support device adopts Li Nuoer damper structure, both ensure that the stability of linear running, again the crossing ability of accommodation curve; Axie box support device adopts rubber spring, has rigidity and the damping in vertical, horizontal and vertical three directions, and structure is simple, is easy to safeguard.
3. integrated form foundation brake rigging adopts suspension rod composition to be connected with framework, reduces unsprung weight, reduces wheel-rail force, be conducive to the dynamic performance improved in vehicle operation.
4. the hanging of integrated form foundation brake rigging is on framework composition, and when car brakeing is alleviated, integrated form foundation brake rigging is only subject to the friction drag forming junction with framework, and this friction drag is relatively little, improves release of brake performance.
5. brake equipment is integrated form foundation brake rigging, has used the principle of design of parallelogram, can transmit best braking characteristics; Compared with traditional foundation brake rigging, deadweight reduces, and brake efficiency improves, and device sensitivity is high, can improve braking force to a certain extent, effectively can reduce the abrasion of brake shoe and wheel rim.
