Described crossbeam coordinates and is provided with elastic side bearing composition, crossbeam center is provided with ball center plate, and described framework composition is connected with car body with ball center plate by elastic side bearing composition.
Described crossbeam is also fixed with brake equipment flap seat, and described brake equipment flap seat forms with suspension rod and is connected.
Described integrated form foundation brake rigging comprises two brake cylinder compositions, brake cylinder composition is adjusted device to form with lock to be connected, lock adjusts device composition to become one with push rod, and the both sides of described push rod all connect brake head, and described brake cylinder composition, lock adjust device composition and push rod to be integrated into parallelogram sturcutre; The piston action power of brake cylinder composition is applied to after on push rod and lock tune device by internal lever and is delivered to brake head.
The two ends that described integrated form foundation brake rigging is provided with brake cylinder composition are provided with handwheel composition, provide hand brake force, meet the needs of stopping brake by handwheel composition.
Described Axie box support device comprises axle box composition, described axle box composition both sides are provided with two stage stiffness spring, described two stage stiffness spring top is provided with spring compressor composition, described spring compressor composition is connected with drawing strickle guide body by suspension ring, holder is provided with between described spring compressor and axle box, play the effect of friction damping, both ensure that the stability of linear running, again the crossing ability of accommodation curve.
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.
The beneficial effects of the utility model are:
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.
