Abstract
The invention discloses an automobile frame longitudinal beam, and mainly relates to a structure of a mounting hole in an automobile frame longitudinal beam. The technical scheme is as follows: the utility model provides a mounting hole is distributed to the carframe longeron, and the mounting hole is divided two rows along carframe longeron length direction and is arranged, and every row of mounting hole is equidistant distribution, and the interval is not more than 200 millimeters, and the best is 50 millimeters. The mounting holes on the longitudinal beam are regularly and tidily arranged, so that the longitudinal beam is easy to process, the systematization, standardization and universalization degrees during vehicle type development are improved, and the development period and the cost of seriation vehicle types are reduced. Meanwhile, the refitting vehicle is convenient to use, the refitting cost and the refitting difficulty are reduced, and the refitting efficiency is improved.
Description
Technical field
The present invention relates to a kind of automobile chassis frame, refer in particular to the girder work of automobile chassis frame.
Background technology
For each big assembly and parts are installed, need a lot of different mounting hole site, on the load-carrying vehicle vehicle frame referring to Fig. 3, mounting hole 6 on the existing chassis side rail 5 generally is to determine according to the installation site of each assembly and parts on the car load, not of uniform size, disorderly and unsystematic, have no rule and can say.Not only bad for processing, and be unfavorable for very much reequiping the repacking of depot, and bring more change for the exploitation of seriation vehicle, increased the time-to-market and the cost of development of seriation vehicle.Simultaneously, the car type difference of each refitting factory repacking, therefore the demand that the layout on chassis is also had nothing in common with each other, each refitting factory changes the deployment scenarios of each system of chassis according to the demand of oneself reequiping, and certainly will will increase mounting hole site on chassis side rail according to the repacking situation, thereby cause the position, hole on the chassis side rail various more in a jumble, simultaneously will cause chassis side rail partial bores position concentrations inevitably, weaken the intensity of vehicle frame to some extent, reduce the load-carrying capacity of car load.And because a lot of refitting factory does not have the chassis side rail punch device of specialty, therefore the very difficulty of punching on chassis side rail, has increased modification difficulty, has reduced the work efficiency of refitting factory.
Summary of the invention
In order to solve the problem that existing position, load-carrying vehicle vehicle frame hole is various in a jumble, be unfavorable for the development of car load repacking and seriation vehicle, the invention provides a kind of automobile chassis frame that has the gauge orifice position, reduce the repacking cost, improve the universalization degree of vehicle frame.
Technical scheme of the present invention is: a kind of load-carrying vehicle vehicle frame, be distributed with mounting hole on the chassis side rail, and mounting hole divides two row to arrange along the chassis side rail length direction, is respectively mounting hole 2 and following mounting hole.
Every capable mounting hole is equidistantly to distribute, and spacing is not more than 200 millimeters.
When being used for the seriation vehicle, the mounting hole that distributes on the chassis side rail can satisfy the installation requirements of each assembly and parts diverse location.
When carrying out the car load repacking, can on vehicle frame, move the installation site of each big assembly according to the repacking demand, find suitable mounting hole site, and needn't increase new mounting hole because the installation site changes.
Beneficial effect of the present invention is as follows:
Load-carrying vehicle vehicle frame of the present invention, the mounting hole arrangement regulation on the longeron, neat not only is easy to processing, and universalization degree height, has improved systematization, normalisation, universalization degree when developing vehicle, has reduced the time-to-market and the cost of seriation vehicle.Simultaneously, be convenient to remoulded car and use, reduced repacking cost and difficulty, improved repacking efficient.
The present invention will be further described below by the specific embodiment.
Description of drawings
Fig. 1 is that mounting hole is arranged scheme drawing on embodiment 1 chassis side rail.
Fig. 2 is that mounting hole is arranged scheme drawing on embodiment 2 chassis side raiies.
Fig. 3 is that mounting hole is arranged scheme drawing on the prior art chassis side rail.
The specific embodiment
Embodiment 1:
Referring to Fig. 1, be load-carrying vehicle chassis side rail 1, be distributed with mounting hole 2 and following mounting hole 3 on the chassis side rail 1, upper and lower mounting hole 2,3 divides two row to arrange along chassis side rail 1 length direction, and every capable mounting hole is equidistantly to distribute, and spacing is the 50-200 millimeter; Last mounting hole 2 is near chassis side rail 1 upper ends, and the distance between last mounting hole 2 and chassis side rail 1 upper surface satisfies the requirement of installing space; Following mounting hole 3 is near chassis side rail 1 lower end, distance between following mounting hole 3 and chassis side rail 1 lower surface also satisfies the requirement of installing space, and it is equal apart from the distance of chassis side rail 1 lower surface apart from the distance and the following mounting hole 3 of chassis side rail 1 upper surface to go up mounting hole 2.
Embodiment 2:
Present embodiment automobile chassis frame longeron 1 has identical inscape with embodiment 1 automobile chassis frame longeron 1, therefore, corresponding inscape is adopted common term and Reference numeral, and omits the repeat specification of same structure.
Referring to Fig. 2, in the present embodiment, to be mainly mounting hole 2 unequal apart from the distance of chassis side rail 1 lower surface apart from the distance and the following mounting hole 3 of chassis side rail 1 upper surface with the difference of embodiment 1.
On this basis, the also variable non-equidistance that is changed to of the spacing between each hole of every capable mounting hole is as long as arrange according to certain rules.
In sum, the beneficial effect of above embodiment is as follows:
Reduce the repacking cost, accelerated the work efficiency of repacking depot, also accelerated the research and development speed of repacking vehicle simultaneously greatly.Simultaneously, also increase our systematization, normalisation, the universalization degree when the exploitation vehicle, reduced the chassis deadweight.Also reduce simultaneously the time-to-market and the cost of vehicle.
Mounting hole is that the 50-200 millimeter is uniform according to spacing, can satisfy the operating needs of seriation vehicle and repacking vehicle.
Upper and lower mounting hole 2,3 is arranged near chassis side rail 1 upper/lower terminal face respectively, has been reduced the influence to chassis side rail 1 intensity.
