Abstract

The utility model relates to a two-stage stepping rear natural gas bus chassis with a novel arrangement structure of steel cylinders. Three connecting cross beams are uniformly arranged on a frame between a front axle and a rear axle; six natural gas steel cylinders are horizontally distributed and suspended at the lower parts of the three connecting cross beams; one pair of natural gas steel cylinders are arranged in the middle of the frame, and the other two pairs of natural gas steel cylinders are respectively arranged at two sides of the frame; and three gas holders are respectively arranged on a longitudinal beam of the frame at one side of the rear axle. The rear natural gas bus realizes two-stage stepping; the steel cylinders are all arranged on the chassis, so as to ensure the trafficability of the whole vehicle and the safety of the steel cylinders; the center of gravity of the whole vehicle is reduced, the braking durability and reliability are improved, and the manipulation stability is improved; the steel cylinders are fixedly designed in the lower hanging manner, the disassembling is convenient, the maintenance and repair are convenient, and the maintenance service fees are reduced.

Description

The rearmounted natural fuels bus of the two-stage stepping of the new arrangement structure of steel cylinder chassis
Technical field
The utility model belongs to the vehicle chassis technology field, is specifically related to natural fuels bus chassis.
Background technology
Rearmounted bus using natural gas is generally taked two kinds of steel cylinder arrangements: (1) steel cylinder is arranged on the chassis, because of limited by the steel cylinder arrangement space, bus must be made three grades and mark time, like this with regard to inconvenient passenger getting on/off, especially children and old man are more inconvenient as bus, influence bus running efficient, the car load center of gravity is higher simultaneously, car weight is big, and the car load operation stability is poor, is an acid test to braking especially; (2) steel cylinder is arranged on the roof, adopt two-stage stepping, but this arrangement car load center of gravity is higher, braking and tire is required very high, and whole vehicle stability, road-holding property are poor, maintenance difficult, and to body framwork requirement of strength height, cost increases;
The utility model content
Guarantee to continue a journey more than 200 kilometers mileage by enough steel cylinders in order to arrange on the chassis that is implemented in 7-12 rice two-stage stepping bus using natural gas, the utility model provides the rearmounted natural fuels bus of the two-stage stepping chassis of the new arrangement structure of a kind of steel cylinder.
Concrete structural development technical scheme is as follows:
The rearmounted natural fuels bus of the two-stage stepping of the new arrangement structure of steel cylinder chassis, comprise steel cylinder, vehicle frame, propons, back axle, air receiver and driving engine, described driving engine places on the vehicle frame at back axle rear portion, and described vehicle frame is the low floor dissymmetrical structure, and vehicle frame comprises propons and back axle.Be laid with three and connect crossbeam on the vehicle frame between propons and the back axle, six transversely arranged hanging of natural gas steel cylinder are located at three bottoms that connect crossbeam, and wherein a pair of natural gas steel cylinder is positioned at the vehicle frame middle part, and two pairs of natural gas steel cylinders lay respectively at the vehicle frame both sides in addition; Described air receiver is located on the vehicle frame on the preceding right side of back axle.
Described every connection bottom, crossbeam both sides is respectively equipped with the connection column, the connection column of both sides lays respectively at the vehicle frame both sides, every connection crossbeam is captiveed joint with chassis side rail top by cross-beam connecting plate respectively, and every connects crossbeam and captives joint with sidepiece with chassis side rail top by the body contact plate respectively.
Described every pair of natural gas steel cylinder three positions before, during and after the body are hung the bottom that is connected crossbeam at three by shroud ring with three overbolts respectively; The shroud ring holder is every pair of natural gas steel cylinder bottom, and the centre of shroud ring is being connected the bottom that connects crossbeam by three overbolts respectively with both sides.
The utility model is compared with prior art products and is had the advantage of following aspect:
1, rearmounted natural fuels bus steel cylinder all is arranged on the chassis and realizes two-stage stepping, and convenient for passenger to get on and off improves bus running efficient.
2, reduce the car load center of gravity, improve braking durability and reliability, promote and control stability.
3, reduce car weight, cost-cutting promotes the servicing ease.
4, the steel cylinder Fixed Design is the below suspending way, convenient disassembly, and convenient for maintaining and maintenance reduce the maintenance service expense.
Description of drawings
Fig. 1 is the utility model structural representation,
Fig. 2 is the birds-eye view of Fig. 1,
Fig. 3 is that the A of Fig. 1 is to enlarged view.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is done to describe further by embodiment.
Referring to Fig. 1 and Fig. 2, the rearmounted natural fuels bus of two-stage stepping chassis comprises vehicle frame 4, propons 6, back axle 7 and driving engine 5 and three air receivers 3, and driving engine 5 places on the vehicle frame at back axle 7 rear portions.On the vehicle frame between propons 6 and the back axle 7, be laid with three and connect crossbeam 1, six natural gas steel cylinder 2 transversely arranged hanging are located at three bottoms that connect crossbeam 1, wherein a pair of natural gas steel cylinder is positioned at the vehicle frame middle part, and two pairs of natural gas steel cylinders lay respectively at the vehicle frame both sides in addition.
