Abstract
The utility model discloses a steering shaft reinforcing piece of a bogie. The side wall of the front portion and the side wall of the back portion of the bogie are provided with connecting plates which are provided with bolt holes. The reinforcing piece comprises a U-shaped reinforcing protection rod, and the two ends of the reinforcing protection rod are provided with fixing bolt bases. Each fixing bolt base comprises two symmetrical arm pieces with bolt holes, the connecting plates are inserted into the positions between the arm pieces of the corresponding fixing bolt bases to be fixed through connecting bolts, the outer wall of the reinforcing protection rod is provided with a groove, reinforcing ribs are formed between the two ends of the groove and the corresponding fixing bolt bases, the inner wall of the reinforcing protection rod is provided with a boss, and the top face of the boss makes contact with the outer wall of the steering shaft. The steering shaft reinforcing piece of the bogie is simple in structure, easy to manufacture and low in production cost, the weight of the reinforcing piece is reduced through the groove formed in the outer wall of the reinforcing protection rod, materials are saved, the load to the bogie from the reinforcing piece is reduced, the reinforcing ribs are formed at the roots of the fixing bolt bases, namely, the joints of the arm pieces and the reinforcing protection rod, and the strength of the connecting structure of the reinforcing piece and the bogie is improved while the overall strength of the reinforcing piece is guaranteed.
Description
Technical field
The utility model relates to a kind of reinforcement, specifically, is a kind of steering shaft reinforcement of bogie truck.
Background technology
Bogie truck is a kind of mechanism that adjusts sense of motion, and bogie truck is all provided with a steering shaft, and steering shaft below is a L shaped wheel seat, and wheel is arranged on wheel seat.When load is larger, the junction of steering shaft and wheel seat can deform and bend, and after long-time use, bogie truck can rupture, and causes vehicle overturning, and goods is unrestrained.
Existing enhancement measures is that a reinforcement is installed on steering shaft, support wheel base, stops the bending of junction, and the reinforcement using is at present a U-shaped cuff, in order to guarantee the intensity of reinforcement itself, the thickness of cuff is larger, but when load is larger, wheel seat can upwards be pushed cuff, make cuff pull the junction of itself and steering shaft, the connection structure of cuff is broken, made bogie truck lose intensity support and rupture, cause danger.And the larger cuff of thickness, weight is also larger, has increased the load of bogie truck, has weakened the effect that reinforcement is reinforced.
Utility model content
The utility model, for above-mentioned the deficiencies in the prior art, has designed a kind of steering shaft reinforcement of new bogie truck.
The steering shaft reinforcement of bogie truck of the present utility model, be arranged on the steering shaft of bogie truck, the sidewall of steering shaft front and rear is all provided with connecting panel, connecting panel is provided with keyhole, reinforcement comprises U-shaped reinforcement guard bar, strengthen guard bar two ends and be provided with fixedly bolt seat, described fixedly bolt seat comprises symmetrically arranged two arm parts with keyhole, connecting panel is inserted between the arm part of fixing bolt seat and fixes by coupling bar, on the outer wall of reinforcement guard bar, be provided with groove, the two ends of groove fixedly form a reinforced rib with corresponding between bolt seat, on the inwall of reinforcement guard bar, be provided with boss, the end face of boss contacts with the outer wall of steering shaft.
The beneficial effects of the utility model are: the steering shaft reinforcement structure of bogie truck is simple, be easy to manufacture, productive costs is low, the groove of strengthening the setting of guard bar outer wall has reduced the weight of reinforcement, has saved materials, has alleviated the load that reinforcement brings to bogie truck, and at the fixing root of bolt seat, namely arm part has formed a reinforced rib with strengthening guard bar junction, when guaranteeing the bulk strength of reinforcement, has improved the intensity of reinforcement and steering shaft connection structure.Strengthen the boss that guard bar inwall arranges, strengthened the support strength of reinforcement inside to steering shaft, also improved the bending strength of reinforcement itself.
Accompanying drawing explanation
The three-dimensional structure diagram that accompanying drawing 1 is reinforcement;
The plan structure figure that accompanying drawing 2 is reinforcement;
The use constitution diagram that accompanying drawing 3 is reinforcement.
The specific embodiment
The steering shaft reinforcement of bogie truck of the present utility model, as shown in Figures 1 to 3, be arranged on the steering shaft 1 of bogie truck, the sidewall of steering shaft 1 front and rear is all provided with connecting panel 2, connecting panel 2 is provided with keyhole, reinforcement comprises U-shaped reinforcement guard bar 3, strengthen guard bar 3 two ends and be provided with fixedly bolt seat 4, described fixedly bolt seat 4 comprises symmetrically arranged two arm parts 5 with keyhole, connecting panel 2 is inserted between the arm part 5 of fixing bolt seat 4 and is fixing by coupling bar 6, on the outer wall of reinforcement guard bar 3, be provided with groove 7, between the two ends of groove 7 and corresponding fixedly bolt seat 4, form a reinforced rib 8, on the inwall of reinforcement guard bar 3, be provided with boss 9, the end face of boss 9 contacts with the outer wall of steering shaft 1.
Due to load; underrun wheel 11 makes wheel seat 10 have the upwards trend of bending; reinforcement is arranged on the root of steering shaft 1; the junction of steering shaft 1 and wheel seat 10 namely; wheel seat 10 is played to the effect of support; wheel seat 10 there is is upwards bend the power of trend to be applied on reinforcement, play the effect of more protection.
Reinforcement surface is provided with copper facing coating, has improved the tensile strength of reinforcement.
