Abstract
The utility model discloses a passenger train frame crossbeam, it includes the crossbeam body, and the crossbeam body comprises crossbeam web and crossbeam curb plate, and crossbeam curb plate symmetry sets up at the horizontal both ends of crossbeam web, beats the fixed orifices that is equipped with a plurality of transition joint that are arranged in fixed brake pipe way on the crossbeam web. The utility model discloses but the fixed orifices of beating at the beam web and establish the transition joint in the directly fixed brake piping, the fixed orifices matches each other with the transition joint, the fixed orifices in the beam web is directly passed to the transition joint during assembly, through interference fit between the two or screw up the nut that sets up at the transition joint both ends, can effectively fix the transition joint, the use of fixed bolster when having avoided the transition joint fixed, the assembly degree of difficulty has been reduced, the efficiency of construction is improved, it is corresponding also to have reduced whole weight, and the production cost is reduced.
Description
Technical field
The utility model relates to automobile technical field, refers to it is a kind of bus frame crossbeam that is applied to have in low floor or the two-stage stepping passenger vehicle pipeline crossover sub fixed orifice particularly.
Background technology
At present, the brake piping on the passenger vehicle adopts flexible pipe more, but the brake piping of low floor or two-stage pedal passenger vehicle for reserving enough propons jitter space, is protected brake piping when crossing propons, and the propons top adopts the steel pipe transition to realize this purpose.Therefore, in brake piping, need to increase steel pipe is connected usefulness with flexible pipe crossover sub, and be that crossover sub is fixed on the cross member of frame, prior art adopts fixed support to fix more, be that crossover sub is contained on the fixed support earlier in advance, then with fixed support by bolt to cross member of frame, this scheme need increase third party's attaching partss such as fixed support and bolt, just increased the cross member of frame deadweight accordingly, and the mounting process of crossover sub is loaded down with trivial details.
Chinese patent 200910221349.7 discloses a kind of integrated frame cross member on November 05th, 2009, it comprises the support portion and is connected the left installation portion and the right installation portion at support sector two ends, on left installation portion and right installation portion, be provided with the connecting bore that is used to install connecting panel, be provided with lightening hole at support portion and left installation portion and right installation portion, has economical with materials, the characteristics of cost-cutting.But can not solve the loaded down with trivial details problem of mounting process that increases cross member of frame deadweight and crossover sub because of the installation of crossover sub.Therefore, need prior art is improved.
The utility model content
The purpose of this utility model is exactly the deficiency that will solve the above-mentioned background technology, and a kind of reasonable in design is provided, can be directly fixedly pipeline connect the bus frame crossbeam of the crossover sub of usefulness.
The technical solution of the utility model is: a kind of bus frame crossbeam, it comprises cross-beam body, described cross-beam body is made of cantilever diaphragm and crossbeam side plate, described crossbeam side plate is symmetricly set on the transverse ends of cantilever diaphragm, it is characterized in that: set a plurality of fixed orifices that are used for fixing the crossover sub in the brake piping on described cantilever diaphragm.
Be preferably, described fixed orifice is opened on the cantilever diaphragm side by side.
Further, vertical two ends of described cantilever diaphragm offer U type hole.
Further, also offer a plurality of lightening holes on the described cantilever diaphragm.
The utility model fixed orifice that the cantilever diaphragm of bus frame crossbeam sets can be directly the fixing crossover sub in the brake piping, fixed orifice and crossover sub mate mutually, crossover sub directly passes the fixed orifice in the cantilever diaphragm during assembling, by the interference fit between the two or tighten the nut that is arranged on the crossover sub two ends, effectively fixing crossover sub, support bracket fastened use when having avoided crossover sub fixedly, reduced assembly difficulty, improved operating efficiency, also reduce overall weight accordingly, reduced productive costs; And U type hole and lightening hole that the correct position on cantilever diaphragm is offered can effectively alleviate overall weight, and lightening hole can also rationally utilize, and by the hole, save the space as pipeline.
Description of drawings
Fig. 1 is the utility model integral structure scheme drawing.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, is convenient to be well understood to the utility model, but they do not constitute qualification to the utility model.
As shown in Figure 1, a kind of bus frame crossbeam, it comprises cross-beam body 4, cross-beam body 1 is made of cantilever diaphragm 5 and crossbeam side plate 6, crossbeam side plate 6 is symmetrically welded at the transverse ends of cantilever diaphragm 5, on cantilever diaphragm 5, set a plurality of fixed orifices 1 that are used for fixing the crossover sub in the brake piping side by side, fixed orifice 1 mates mutually with crossover sub, crossover sub directly passes the fixed orifice 1 in the cantilever diaphragm 5 during assembling, by the interference fit between the two or tighten the nut that is arranged on the crossover sub two ends, effectively fixing crossover sub, support bracket fastened use has reduced assembly difficulty when having avoided crossover sub fixedly, has improved operating efficiency, also reduce overall weight accordingly, reduced productive costs.The U type hole of offering at vertical two ends of cantilever diaphragm 52 also offers a plurality of lightening holes not of uniform size 3 on cantilever diaphragm 2, can effectively alleviate overall weight, and lightening hole 3 can also rationally utilize, and by the hole, saves the space as pipeline.
The utility model is reasonable in design, be a kind of can be directly effectively fixedly pipeline connect the bus frame crossbeam of the crossover sub of usefulness.
