Abstract
The utility model discloses a passenger train chassis frame combination crossbeam, it includes piece under the last piece of crossbeam and two crossbeams, the both ends of terminal surface under the last piece of crossbeam are fixed respectively to the piece under two crossbeams, its characterized in that: all be equipped with the hole that a plurality of is used for reducing the concentrated stress on the crossbeam under piece and two crossbeams on the piece, be equipped with protrudingly on the crossbeam on the piece, all be equipped with down protrudingly under two crossbeams on the piece. The utility model discloses a strengthening rib with subtract the stress hole and has guaranteed that the crossbeam under the prerequisite of guaranteeing to arrange transmission system and be correlated with pipeline, pencil arranging, has sufficient intensity, can satisfy the demand that length was not more than 10m passenger train frame cross, practiced thrift the manpower greatly, improve production efficiency, its simple structure, low in manufacturing cost easily promotes.
Description
Technical field
The utility model relates to vehicle beam technical field, particularly a kind of passenger-carrying chassis vehicle frame combination crossbeam.
Background technology
Passenger-carrying chassis cross member of frame under the prerequisite possessing sufficient intensity, need be easy to the layout of transmission shaft, brake system associated components, meanwhile, be convenient to the layout of Car Harnesses and brake piping, and make it trend rationally, layout is clear; But the crossbeams such as traditional flute profile, arch also exist some defects, such as, in order to ensure that enough intensity needs the connecting panel increasing beam thickness or increase between crossbeam and longeron, the cost of this crossbeam not only increased but also make crossbeam outward appearance too too fat to move, unsightly; In addition, the tradition crossbeam lower aerofoil ground Clearance is too low, be unfavorable for that preposition secondary is marked time the layout of chassis transmission shaft, adding traditional crossbeam is the limited space that proof strength keeps for chassis brake piping, electrical equipment wiring harness and oil pipe water pipe, causes associated pipe in the inconvenience of installing and in maintenance.
Utility model content
The purpose of this utility model is the passenger-carrying chassis vehicle frame combination crossbeam providing a kind of structure simple, easy to use to overcome above-mentioned deficiency.
The utility model is achieved in that a kind of passenger-carrying chassis vehicle frame combination crossbeam, it comprises crossbeam upper slice and two crossbeam bottom sheet, described two crossbeam bottom sheet are separately fixed at the two ends of crossbeam upper slice lower surface, it is characterized in that: described crossbeam upper slice and two crossbeam bottom sheet are equipped with several for reducing the hole of concentrated stress, described crossbeam upper slice is provided with projection, and described two crossbeam bottom sheet are equipped with lower convexity.
Described crossbeam upper slice is fixedly connected with by tie bolt with two crossbeam bottom sheet.
The diameter in described hole is 5-10mm.
Reinforced rib of the present utility model and subtract stress hole and ensure that crossbeam is ensureing driveline arrangement and associated pipe, under prerequisite that wire harness is arranged, have enough intensity, the demand that length is not more than 10m bus frame crossbeam can be met, greatly save manpower, enhance productivity, its structure is simple, low cost of manufacture, is easy to promote.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the front elevation of Fig. 1.
Detailed description of the invention
The utility model is further illustrated below in conjunction with drawings and Examples.
Embodiment: a kind of passenger-carrying chassis vehicle frame combination crossbeam, it comprises crossbeam upper slice 1 and two crossbeam bottom sheet 2, two crossbeam bottom sheet 2 are separately fixed at the two ends of crossbeam upper slice 1 lower surface, crossbeam upper slice 1 and two crossbeam bottom sheet 2 are equipped with several for reducing the hole 11 of concentrated stress, crossbeam upper slice 1 is provided with projection 12, two crossbeam bottom sheet 2 are equipped with lower convexity 21, and crossbeam upper slice 1 is fixedly connected with by tie bolt 3 with two crossbeam bottom sheet 2, and the diameter in hole 11 is 5-10mm; The cavity formed between crossbeam upper slice 1 and two crossbeam bottom sheet 2 is used for pipeline to be passed through, projection 12 and lower convexity 21 and hole 11 make combination crossbeam ensure under the prerequisite that driveline arrangement and associated pipe, wire harness are arranged, have enough intensity, the demand that length is not more than 10m bus frame crossbeam can be met, greatly saved manpower, enhanced productivity, its structure is simple, low cost of manufacture, is easy to promote.
