But, because speed changing assembly is connected with rear-wheel device 02, need below vehicle body, use longer transmission shaft that speed changing assembly is connected with rear-wheel device 02, and vehicle body is body-chassis frame construction, front wheel device 01 and rear-wheel device 02 are dependent suspension gear, cause public transport vehicle chassis higher, pedestrian enters car body needs multiple step, is not easy to pedestrian and gets on or off the bus.On the other hand, driving engine is the diesel motor that discharge capacity is larger, and consumption of fuel is large, and traffic cost is higher.
Therefore, how being convenient to while pedestrian gets on or off the bus, reduce traffic cost, is those skilled in the art's technical matterss urgently to be resolved hurrily.
Utility model content
The purpose of this utility model is to provide a kind of bus, so that pedestrian gets on or off the bus, reduces traffic cost.
For achieving the above object, the utility model provides a kind of bus, comprise vehicle body, front wheel device, rear-wheel device, driving engine and speed changing assembly, the input end of described speed changing assembly is connected with described driving engine, described vehicle body is self-supporting body, described front wheel device and described rear-wheel device are independent suspension device, and described driving engine is the diesel motor that discharge capacity is not more than 2L, and the mouth of described speed changing assembly is connected with described front wheel device by transmission shaft.
Preferably, the maximum speed of revolution of described driving engine is not less than 4000 revs/min.
Preferably, speed changing assembly comprises change-speed box and the main reduction gear that is connected with described change-speed box and differential assembly, described transmission input is connected with described engine output end, described transmission output is connected with the input end of described main reduction gear and differential assembly, and described main reduction gear is connected with described front wheel device by described transmission shaft with the mouth of described differential assembly.。
In technique scheme, the bus that the utility model provides comprises vehicle body, front wheel device, rear-wheel device, driving engine and speed changing assembly, the input end of speed changing assembly is connected with driving engine, vehicle body is self-supporting body, front wheel device and rear-wheel device are independent suspension device, driving engine is the diesel motor that discharge capacity is not more than 2L, and the mouth of speed changing assembly is connected with front wheel device by transmission shaft.When bus running, driven by engine speed changing assembly runs, and speed changing assembly drives the tyre rotation of front wheel device, and the tire of last rear-wheel device rotates under the effect of vehicle body.
Known by foregoing description, in the bus that the utility model provides, because speed changing assembly is connected with front wheel device, effectively shorten the length of transmission shaft, avoid the situation that degradation of energy in transmittance process is more, and by bus is set to preposition front drive device, avoid transmission shaft to be arranged on situation between front wheel device and rear-wheel device.Meanwhile, because vehicle body is self-supporting body, and front wheel device and rear-wheel device are independent suspension device, significantly reduce the height of vehicle body.On the other hand, the discharge capacity due to driving engine is the diesel motor being not more than 2L, and the discharge capacity of driving engine is less, reduces the traffic cost of bus.

Detailed description of the invention
Core of the present utility model is to provide a kind of bus, so that pedestrian gets on or off the bus, reduces traffic cost.
In order to make those skilled in the art understand the technical solution of the utility model better, below in conjunction with drawings and embodiments, the utility model is described in further detail.
Please refer to Fig. 2, in a kind of detailed description of the invention, the bus that the utility model provides comprises vehicle body, front wheel device 1, rear-wheel device 2, driving engine 3 and speed changing assembly 4, the input end of speed changing assembly 4 is connected with driving engine 3, vehicle body is self-supporting body, front wheel device 1 and rear-wheel device 2 are independent suspension device, driving engine 3 is not more than the diesel motor of 2L for discharge capacity, the mouth of speed changing assembly 4 is connected with front wheel device 1 by transmission shaft, preferably, speed changing assembly 4 comprises change-speed box and the main reduction gear that is connected with change-speed box and differential assembly, transmission input is connected with driving engine 3 mouth, transmission output is connected with the input end of main reduction gear and differential assembly, main reduction gear is connected with front wheel device 1 by transmission shaft with the mouth of differential assembly.Preferably, the maximum speed of revolution of driving engine 3 is not less than 4000 revs/min, because the rotating speed of driving engine 3 is higher, can produce larger horsepower in equal steam discharge car, certainly, according to actual road conditions, rotating speed also can be selected lower than the driving engine 3 of 4000 revs/min.Preferably, this bus is small-sized bus, and in vehicle body, seat is preferably 20 to 30.
When bus running, driving engine 3 drives speed changing assembly 4 to run, and speed changing assembly 4 drives the tyre rotation of front wheel device 1, and the tire of last rear-wheel device 2 rotates under the effect of vehicle body.
Known by foregoing description, in the bus that the utility model specific embodiment provides, because speed changing assembly 4 is connected with front wheel device 1, effectively shorten the length of transmission shaft, avoid the situation that degradation of energy in transmittance process is more, and by bus is set to preposition front drive device, avoid transmission shaft to be arranged on situation between front wheel device 1 and rear-wheel device 2.Meanwhile, because vehicle body is self-supporting body, and front wheel device 1 and rear-wheel device 2 are independent suspension device, significantly reduce the height of vehicle body.On the other hand, the discharge capacity due to driving engine 3 is the diesel motor being not more than 2L, and the discharge capacity of driving engine 3 is less, reduces the traffic cost of bus.Car load realizes one-level pedal and lower curb mass; Meanwhile, transmission shaft is shorter, improves the mechanical efficiency of driving system, and driving engine 3 is positioned at forward engine room, effectively reduces the motor noise be delivered in compartment.Advanced passenger vehicle engine 3 is guaranteed on the basis of vehicles dynamic performance, achieve good economy performance, quality be light, output per litre is high, target that noise is little, fill up a blank of domestic small-sized mini public transport vehicle, become a bus deeply liked by user and passenger.
Bus is mainly used in the small city public transport such as large size city branch line public transport and county town, and it uses road conditions better, and to grade climbing performance and acceleration capability of overtaking other vehicles not too large requirement, major demands is economy, starting ability and low speed accelerating ability from standstill.According to use needs, in coupling, adopt one grade of large speed ratio to meet starting and starting acceleration request, tend to economic performance in all the other couplings, thus rationally solve the paradox of dynamic property and economy.Light and start fuel-efficient feature in conjunction with complete vehicle quality, achieve the design objective of the low oil consumption of car load.
In this specification sheets, each embodiment adopts the mode of going forward one by one to describe, and what each embodiment stressed is the difference with other embodiments, between each embodiment identical similar portion mutually see.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
