Abstract
The utility model relates to an efficient electric motor coach chassis with a low floor and full truss structure. A frame chassis is formed by fixedly connecting a central main beam, side cross beams, cross beams and longitudinal beams, forming a closed framework type structure; an air suspension mechanism composed of a push rod, a shock absorber and an air bag is arranged on the rear side of the frame chassis; and a motor of an efficient electric driving system is fixed at the rear end of a frame via bolts and shock-absorbing rubber gaskets. The utility model has the benefits that by virtue of the low floor and full truss chassis, the integral vehicle body has uniform stress, light dead weight, steady turning, improved durability and increased safety factor; the arrangement of the air suspension system and a great fall head gate-type front axle structure realizes single-step tramp, thereby improving the sitting comfort; both the manufacturing cost and the use cost of the electric motor coach are reduced; and zero pollution of automobile emission can be realized while the noise pollution is greatly reduced.
Description
Technical field
The utility model relates to the electric vehicle engineering field, specifically a kind of efficient electric motor coach chassis with low floor and full truss structure.
Background technology
Present passenger-carrying chassis is generally fall crossbeam type or half carrying structure, and the vehicle frame on chassis is main stressed member and is bearing from the various load inside and outside the car, also is the important load bearing component of passenger vehicle.Generally higher relatively apart from ground when being provided with, because of all need marking time of secondary or three grades when coming in and going out car door, the inconvenience of getting on or off the bus is difficult to satisfy the requirement of urban passenger low floor specification; Simultaneously, this shortcoming has also been raised the center of gravity of passenger vehicle, and the safety of automobile is reduced greatly.More in addition, it is the focus that people pay close attention to that motor vehicle exhaust emission is polluted always, and along with the reinforcement of social enviroment protection consciousness, all circles all strive for the low pollution of automobile now; In addition, present passenger-carrying chassis is provided with higher, and it is bigger to conduct oneself with dignity.Adopt change speed gear box in the drive system of hybrid power and electrobus, realize the automobile low-speed big, driving efficiency is low.
The utility model content
At above defective, the utility model provides a kind of efficient electric motor coach chassis with low floor and full truss structure, by adopting high-efficiency electric vehicle drive system electric automobile chassis, solve that present ordinary diesel oil chassis is higher, gravity is big, enter that the compartment easily is obstructed, automobile exhaust pollution seriously reaches defectives such as highly energy-consuming.
For achieving the above object, the utility model is by the following technical solutions:
A kind of efficient electric motor coach chassis with low floor and full truss structure, comprise frame chassis, Pneumatic Suspension mechanism and big drop gate-type propons, frame chassis is captiveed joint with longeron by central girder, side crossbeam and each crossbeam and is formed an osed top tower structure, described frame chassis rear side is provided with the Pneumatic Suspension mechanism that is made up of push rod, bumper, air bag, and the crossbeam width of described frame chassis is greater than the crossbeam height; Described big drop gate-type propons is connected in frame chassis by push rod, bumper and the air bag of AIRMATIC Dual Control, push rod wherein directly adopts bolted connection on bearing, a wherein end of bumper and air bag is connected vehicle frame, and the other end is connected the bearing on the vehicle bridge; In the vehicle frame rear end, motor connects driving rear axle by transmission shaft to the motor of described efficient power drive system by bolt and damping elastic mounting, middle no speed-changing mechanism; Automatically controlled administrative unit is by bolt and the damping elastic mounting tail end at vehicle frame, and battery pack distributes and is installed on the middle part and the rear portion of full rectangular tube welded frame body, adopts pulley and guide rail mechanism to realize the maintenance and the replacing of battery pack.
Beneficial effect with efficient electric motor coach chassis of low floor and full truss structure described in the utility model is: adopt low floor and full truss underframe, make car body whole stressed even, not yielding from heavy and light, chassis, bend and stablize, improved durability, improved safety factor excessively; Being provided with of bridge construction realized that single order is marked time and to make things convenient for getting on or off the bus of passenger, side to arrange that air bag and bumper structure make in the vehicle traveling process more steady before AIRMATIC Dual Control and the big drop gate-type, improved the traveling comfort of taking; Low chassis reduces the automobile bottom air and flows, and has increased the downforce in travelling; Stage casing and back segment are arranged battery, make complete vehicle weight be evenly distributed, and center of gravity is reasonable, improves road-holding property; Efficient power drive system can be realized automobile low energy consumption and high efficiency, and energy consumption is less than 0.042kwh, and climbable gradient more than the scooter 120km/h, has also significantly reduced the pollution of noise simultaneously greater than 30% during automobile, can realize the large scale development of public transit vehicle; Improved the bus travelling comfort, install disassembled simply convenient, be convenient to maintenance, system layout is more flexible.
