Abstract
The invention relates to a classis special for urban transport vehicles. The chassis is characterized by comprising a frame assembly, an engine assembly and a low floor cab assembly, wherein the frame assembly consists of front and rear sections of left and right longitudinal beams which are low in front and high in back and have stepped structures; the front section of left and right longitudinal beams is positioned below the cab; the front and rear sections of left and right longitudinal beams are fixedly connected together in an upper-lower lapping manner; the engine assembly is arranged in the space between the rear section of left and right longitudinal beams on the lower side of the engine cabin on the rear part of the cab; the low floor cab assembly is of the passenger car concept and utilizes low floor lower than two-stage step and a broad view design to realize high-level driving comfort; and the frame longitudinal beam on the rear part of the back wall of the cab is provided with a gas cylinder mounting bracket assembly sequentially provided with three gas cylinders from bottom to top and a single gas cylinder suspension rack which is hoisted on the lower wing face of the frame longitudinal beam on the rear part of the rear axle of the chassis and provided with a gas cylinder through connectors.
Description
Technical field
The present invention relates to a kind of vehicle chassis, relate to a kind of chassis special that is applied to the city transportation vehicle specifically.
Background technology
At present, domestic city transport vehicle chassis all is on two types of universal chassis, to convert, and 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 are when getting off or even jump off car, certain influence arranged for the personal safety of chaufeur; And last dress need be connected through subframe when combining with 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 object of the invention provides a kind of chassis special that is applied to the city transportation vehicle to existing weak point in the above-mentioned prior art just.What city transportation vehicle chassis special of the present invention was stressed is the car load design concept, and chassis and last dress can organically combine; The chassis is strong to the comformability of last dress, and equipment structure design and layout can reach more satisfactory state, when operation, can bring into play best performance; And the harmony of car load profile, the operator's compartment assembly adopts the passenger vehicle design concept, and the low floor that is not higher than two-stage stepping designs to realize high ride comfort with the big visual field; The employing compression natural gas acts as a fuel, and can reduce the car load daily operating cost.
The object of the invention can be realized through following technique measures:
The chassis special that is applied to the city transportation vehicle of the present invention comprises frame assembly, engine assembly, low floor operator's compartment assembly; Described frame assembly is made up 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 with the mode that overlaps up and down at joint; Said engine assembly is set in place in the space between the back segment left-right longeron of the machinery space downside of rear cabin; Said 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 that is not higher than two-stage stepping designs to realize high ride comfort with the big visual field); 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, 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 through attaching parts.
Engine assembly described in the present invention is arranged on front axle center line rear portion; Said cab floor floor terrain clearance 735mm, the liftoff 2675mm in operator's compartment top.
Beneficial effect of the present invention is following:
Because vehicle frame body of the present invention 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 is merely 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.
