Abstract
The electrically-driven bus chassis with long axle-base and short rear suspension includes vehicle frame and driving equipment, the vehicle frame is formed from front suspension, middle section and rear suspension, and the driving equipment includes transmission shaft of driving axle, torque divider, speed-changing box, motor, controller and power battery. The utilization of said invention is favorable for making environment-protecting type (zero discharge and low noise) bus.
Description
Technical field
The present invention relates to a kind of electric motor coach chassis, particularly a kind of wheelbase far away, short rear overhang electric motor coach chassis.
Background technology
Present city bus all is to be the automobile of drive source with the fuel engines, not only cause aerial contamination, and because the structure influence that driving engine is provided with, the rear overhang on existing fuel-engined vehicle chassis is longer, forming the chassis propons bears a heavy burden light partially, and it is overweight that back axle is born a heavy burden, bridge load-bearing ratio is unreasonable, unbalanced before and after making the chassis, light before the car load, back weighs and directly causes when moving not steady, the generation phenomenon of jolting, make the passenger especially the passenger of the tailstock endure the hardship of bringing because of the load-bearing problem of jolting and vibrating to the fullest extent.
Summary of the invention
For addressing the above problem, the purpose of this invention is to provide a kind of pollution-free, zero-emission, the wheelbase far away that low noise and stationarity are good, short rear overhang electric motor coach chassis.
The object of the present invention is achieved like this: a kind of wheelbase far away, short rear overhang electric motor coach chassis, comprise vehicle frame and actuating device, vehicle frame is made up of front overhang, stage casing and rear overhang, actuating device comprises drive axle transmission shaft, part-time case, change speed gear box, electrical motor, controller and power battery pack, it is characterized in that: long 1.8～2.5 meters of vehicle frame rear overhang; Electrical motor in the actuating device, change speed gear box and part-time case top interface are linked in sequence and are assemblied in drive axle transmission shaft top, part-time case below interface is connected with the drive axle transmission shaft, form collapsible setting, the drive axle two ends are provided with double rear wheel respectively, and electrokinetic cell is mounted on the rear overhang.
The wheelbase of described vehicle frame front-wheel and trailing wheel is 6m to 8.2m.
Described vehicle frame does not have propons, and two front-wheels can be distinguished independent suspension by suspender.
The left and right sides, described vehicle frame stage casing also can be provided with one group of electrokinetic cell respectively.
Drive system of the present invention adopts collapsible configuration, reduced the shared length space of electrical motor, compare with similar fuel vehicle, can save the about 1.5m in length space, helping the back axle position moves to the tailstock, back axle to the rear overhang of the tailstock significantly shortens, and under the situation of propons invariant position, the stage casing on chassis is that the interaxle distance of front and back wheel is elongated.Normal length is that 10.1 meters passenger-carrying chassis wheel base is about 5 meters, rear overhang is about 3.5 meters, and adopt length of the present invention is 8.5～11.6 meters vehicle frame, rear overhang length is 1.8～2.5 meters, wheel base is greater than 6 meters, with the front-wheel of vehicle frame independent suspension respectively, more can make wheelbase overlength between front-wheel and trailing wheel (the longest reach 8.2 meters).Outstanding length is approaching before and after the chassis of the present invention, double rear wheel is set on the back axle, and power battery pack is positioned over mainly on the rear overhang, by the trailing wheel load-bearing, make the stressed basic equalization of each single-wheel load-bearing of chassis, propons bears a heavy burden to be increased relatively, the back axle load-bearing alleviates relatively, and the car load load-bearing is more reasonable.Use the present invention, help the city bus making environment-friendly type (zero-emission, low noise), operate steadily, thereby reduce aerial contamination and make driving safer, the passenger takes more comfortable.
