A kind of light-duty tourist coach vehicle frame that partly carries
Technical field
The utility model relates to a kind of passenger vehicle accessory, especially relates to a kind of light-duty tourist coach vehicle frame that partly carries.
Background technology
The light-duty tourist coach vehicle frame back segment that partly carries of present domestic postposition adopts two kinds of forms substantially, form wherein: adopted the segmentation longeron with connecting panel bonded assembly method, add tank bracket, driving engine ingot beam, air conditioner compressed machine support etc., make that the weight of this part is heavier, bigger influence is arranged for the economy of car load; Form two: employing be the whole molded method of one section longeron, weight is low weight, avoided the problem of first kind of form, but this mode need be made cooresponding mould, and the tourist coach of China has the characteristics of multi-varieties and small-batch, and under single vehicle quantity was not very big situation, die cost was very big to the influence of cost, and the client of China's passenger vehicle is highstrung to price, so this mode only is fit to big in batches product mono-bus.
Summary of the invention
The purpose of this utility model is exactly that a kind of light weight, the light-duty tourist coach vehicle frame that partly carries that cost is low are provided in order to overcome the defective that above-mentioned prior art exists.
The purpose of this utility model can be achieved through the following technical solutions: a kind of light-duty tourist coach vehicle frame that partly carries, it is characterized in that, go up longeron, back longeron down after comprising, and the reinforcement diagonal brace of longeron under longeron and the back is gone up in the connection back, described back is provided with a plurality of rectangular tube supports respectively before and after the longeron down, is used for installing driving engine, water tank, air-conditioning compressor and empty filter.
Described back longeron down is a rectangular tube.
Described back is provided with 4 rectangular tube supports on the longeron down, is respectively: engine mounting bracket, water tank are installed crossbeam, empty filter mounting bracket and air-conditioning compressor mounting bracket.
Described engine mounting bracket has two, is separately positioned on the back and goes up longeron and back longeron bonded assembly corner and the back transom beam place of longeron down down.
Described water tank is installed crossbeam and is arranged on the rear end of longeron down, back.
Described empty filter mounting bracket is arranged on the back front end of longeron down.
Described air-conditioning compressor mounting bracket is arranged on the A-frame of longeron afterbody under the back.
Compared with prior art, the utility model uses rectangular tube to replace trough girder the back segment longeron, simultaneously tank bracket, air conditioner compressed machine support are also replaced original design with little rectangular tube, cancellation driving engine ingot beam has so just alleviated weight herein well effectively.
This programme is also basic on cost not to be increased, and has avoided the too many drawback of cost increase in the traditional approach two, is fit to the mode of production of the many kinds of present domestic travel passenger vehicle small lot.

Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the birds-eye view of the utility model vehicle frame.
Among the figure: longeron, 5-water tank are installed crossbeam, 6-transom beam, the empty filter mounting bracket of 7-, 8-air-conditioning compressor mounting bracket, 9-triangular support bracket down after going up longeron, 2-reinforcement diagonal brace, 3-engine mounting bracket, 4-behind the 1-vehicle frame.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment 1
