Abstract
The utility model relates to a special chassis applied to urban transport vehicles. The special chassis applied to urban transport vehicles is characterized in that the chassis comprises a vehicle frame assembly, an engine assembly and a low-floor driving cab assembly, wherein the vehicle frame assembly comprises a front left longitudinal beam, a front right longitudinal beam, a rear left longitudinal beam, and a rear right longitudinal beam which are in a step-like structure that the front left and right longitudinal beams are lower than the rear left and right longitudinal beams; and the front left and right longitudinal beams are positioned under the driving cab, and the left longitudinal beam and the right longitudinal beam in the front are fixedly connected with the left longitudinal beam and the right longitudinal beam at the back at butt-joint parts in an up and down lapping mode. The engine assembly is arranged in a space positioned between the rear right and left longitudinal beams under an engine nacelle at the back of the driving cab. The low-floor driving cab assembly adopts a passenger car concept that the low-floor driving cab assembly is provided with a low floor which is not higher than two steps, and a wide view design to realize the high comfort in driving and taking. A gas cylinder installation rack assembly is arranged on the rear longitudinal beams of the vehicle frame at the back of the back side of the driving cab with by connecting pieces, three gas cylinders are orderly arranged on the gas cylinder installation rack assembly from top to bottom, and a single gas cylinder hoisting rack provided with a gas cylinder is arranged on the lower planes of the rear longitudinal beams of the vehicle frame hoisted at a rear axle of the chassis.
Description
Technical field
The utility model relates to a kind of vehicle chassis, relates to specifically a kind of chassis special that is applied to the city transport vehicle.
Background technology
At present, domestic city transport vehicle chassis all is to convert at two class universal chassis, the car chassis overwhelming majority is three grades and marks time, higher floor causes chaufeur extremely inconvenient when getting on or off the bus, the riding manipulation traveling comfort is bad, and many chaufeurs have certain influence for the personal safety of chaufeur when getting off or even beast, and upper dress needs to connect by subframe when be combined in the chassis, causes cost to increase and the more high drawback of car load center of gravity.In addition, because this type of vehicle of prior art adopts diesel oil fuel more, cause the car load operation cost higher.
Summary of the invention
The purpose of this utility model provides a kind of chassis special that is applied to the city transport vehicle for existing weak point in the above-mentioned prior art just.What city of the present utility model transport vehicle chassis special was emphasized is the car load design concept, and chassis and upper dress can organically combine; The chassis is to the strong adaptability of upper dress, and equipment structure design and layout can reach more satisfactory state, can bring into play best performance when operation; And the harmony of car load profile, the operator's compartment assembly adopts the Bus ﹠ Coach Design theory, and the low floor and the large visual field design that are not higher than two-stage stepping are realized high ride comfort; The employing compression natural gas acts as a fuel, and can reduce the car load daily operating cost.
The purpose of this utility model can realize by following technique measures:
The chassis special that is applied to the city transport vehicle of the present utility model comprises frame assembly, engine assembly, low floor operator's compartment assembly; Described frame assembly is comprised of the low early and high after two sections left-right longerons in step-by-step construction front and back that are, and described leading portion left-right longeron is positioned at under-cab, and the two sections left-right longerons in front and back are fixed together in the mode that overlaps up and down at joint; Described engine assembly is arranged in the space between the back segment left-right longeron of the machinery space downside of rear cabin; Described cab floor is passenger vehicle formula low floor two-stage stepping structure (that is to say that described low floor operator's compartment assembly adopts the passenger vehicle theory, the low floor and the large visual field design that are not higher than two-stage stepping are realized high ride comfort); On the chassis side rail of cabin rear wall rear portion, be provided with the gas cylinder mounting bracket assembly that three gas cylinders are installed from the bottom to top successively by attaching parts, and be lifted on the single gas cylinder pylon that a gas cylinder is installed on the chassis side rail lower aerofoil of back axle rear portion, chassis.
Engine assembly described in the utility model is arranged on front axle center line rear portion; Described cab floor floor terrain clearance 735mm, the liftoff 2675mm in operator's compartment top.
The beneficial effects of the utility model are as follows:
Because vehicle frame body of the present utility model adopts the low early and high after two sections left-right longerons in step-by-step construction front and back that are to form, can realize the cab floor two-stage stepping, the floor terrain clearance only is 735mm, and operator's compartment top terrain clearance is 2675mm, can make things convenient for chaufeur to get on or off the bus, handling comfort is good; Realize the use of car load gas fuel, reduce the car load daily operating cost.
