Abstract
The utility model discloses a low floor passenger car frame, including solebar and the boundary beam of setting in solebar both sides, solebar flushes with both sides boundary beam top, and the two top plane is the mounting plane on floor. The utility model discloses simple structure, firm, floor terrain clearance are low, and especially adapted is installed and is used on various passenger cars.
Description
Technical field
The utility model relates to the bus frame of automotive field, refers to a kind of low-floor bus vehicle frame particularly.
Background technology
The vehicle frame of present domestic passenger vehicle, particularly bus generally comprises chassis side rail, side bar and floor frame beam, side bar is fixedly connected on the both sides of chassis side rail, its top is only as installation chassis part or assembly, on longeron, and the paved surface on floor is a floor frame back portion mounting plane to the floor frame beam as an integral installation.Such structure makes that the terrain clearance on floor is very high, generally need establish three to the level Four step, causes passenger's extremely inconvenience up and down.Meanwhile, the higher car load center that also can make of floor level is higher, and vehicle handling and stability and safety factor are difficult to guarantee.
Summary of the invention
The purpose of this utility model is exactly to solve the deficiency that the above-mentioned background technology exists, and proposes a kind of simple in structure, firm, low-floor bus vehicle frame that can effectively reduce the terrain clearance of floor covering layers face.
At above-mentioned purpose, the low-floor bus vehicle frame that the utility model is designed comprises chassis side rail and the side bar that is arranged on the chassis side rail both sides, and described chassis side rail flushes with dual-side back portion, and the two top plan is the mounting plane on floor.
Further, be provided with the tie-beam that is used for load-bearing and reinforcement between the described two adjacent side bars, captive joint with described two adjacent side bars respectively in described tie-beam two ends, its top flushes with chassis side rail and side bar, can be used as seat to be installed and to be strengthened frame strength.
Further, in order further to strengthen weight capacity, described tie-beam adopts the longitudinal and transverse alternative arrangement of mode arranged in a crossed manner.
Advantage of the present utility model is: cancelled the floor frame beam, the floor covering layers frame that replaces original frame-type with chassis side rail and the side bar that flushes with the chassis side rail top and tie-beam, the two top plan directly is set to the floor covering layers face, farthest reduced the terrain clearance on floor, can reach that meeting tier 2 is marked time, the requirement of low floor, be very easy to the passenger about; Simultaneously, such structure effectively reduces the center of gravity of car load, has effectively improved vehicle handling and stability and safety factor; At last, cancel behind original floor frame beam greatly saving in material, reduce manufacturing cost.
Description of drawings
Fig. 1 is the perspective view of low-floor bus vehicle frame;
Fig. 2 is the main TV structure scheme drawing of low-floor bus vehicle frame;
Fig. 3 is the plan structure scheme drawing of low-floor bus vehicle frame.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Low-floor bus vehicle frame as shown in the drawing comprises chassis side rail 1 and the side bar 2 that is arranged on chassis side rail 1 both sides.The two common main body framework that constitutes vehicle frame, described chassis side rail 1 flushes with both sides side bar 2 tops, and the two top plan is as the mounting plane on floor 3.Floor 3 is laid immediately on chassis side rail 1 and the formed plane, both sides side bar 2 tops, cancelled the floor covering layers skeleton of original frame-type, make the attachment face and the plane, place, chassis side rail 1 top on floor 3 be in sustained height, reduced the setting height(from bottom) on floor to greatest extent.And because passenger vehicle is mainly used in the delivery passenger, its maximum load is compared much lower than lorry, therefore cancel the floor covering layers frame of frame-type, change into above-mentionedly by chassis side rail 1 and the laying frame of both sides side bar 2 as floor 3, its load-carrying capacity also can meet the demands fully.The high material of preferred intensity in this patent uses the big connection mode of anchoring strength simultaneously, strengthens the bulk strength and the load-carrying capacity of vehicle frame, to guarantee safety.
For improving the bearing capacity at seat place, between the described two adjacent side bars 2 tie-beam 4 that also can be used for load-bearing is set.Captive joint with described two adjacent side bars 2 respectively in described tie-beam 4 two ends, its top flushes with chassis side rail 1 and side bar 2, forms forcefully at 3 places, floor of bus seat bottom and support, and guarantees its steadiness.In order further to gain in strength, described tie-beam 4 adopts the decussate texture of longitudinal and cross beam alternative arrangement, adopts the mode and the side bar 2 of welding to be connected.
Claims (4)
1, a kind of low-floor bus vehicle frame comprises chassis side rail (1) and is arranged on the side bar (2) of chassis side rail (1) both sides that it is characterized in that: described chassis side rail (1) flushes with both sides side bar (2) top, and the two top plan is the mounting plane of floor (3).
2, according to the described low-floor bus vehicle frame of claim 1, it is characterized in that: floor (3) are directly installed on described chassis side rail (1) and both sides side bar (2) top plan.
3, according to claim 1 or 2 described low-floor bus vehicle frames, it is characterized in that: be provided with the tie-beam (4) that is used for load-bearing between described adjacent two side bars (2), captive joint with described adjacent two side bars (2) respectively in described tie-beam (4) two ends, its top flushes with chassis side rail (1) and side bar (2).
4, according to the described low-floor bus vehicle frame of claim 3, it is characterized in that: described tie-beam (4) adopts the longitudinal and transverse alternative arrangement of mode arranged in a crossed manner.
