Abstract
The utility model relates to a special chassis of an electric coach, aiming at overcoming the problem that in the prior art, the bearing of the chassis and the distribution of the gravity center of the coach are unreasonable. The special chassis consists of a coach frame and a drive motor power assembly, a multi-gear speed changer, a front axle, a rear drive axle, a power battery group, a whole coach braking system, a power steering system and a chassis assembly formed by an air-conditioning compressor which are arranged on the coach frame. The special chassis is characterized in that the power battery is concentratedly arranged at a support lifting frame arranged in the coach frame; and the drive motor power assembly and a linked multi-gear speed changer are arranged at the rear part of the coach frame.
Description
Technical field: the present invention relates to a kind of electrobus chassis special, specially refer to the electric motor coach chassis of back centrally-mounted driving and mid-lifting electrokinetic cell.
Technical background: present existing electric motor coach chassis great majority are improved on original fuel oil passenger vehicle.General employing directly is installed in vehicle frame drive wheels on the position of back axle to motor and travels, and is very unfavorable with fuel oil passenger vehicle comparison performance still.Being included on the chassis of original fuel oil passenger vehicle the installation site of repacking battery arbitrarily, thereby making the chassis carrying of car load and the center of gravity of car lose original characteristic, is not very desirable, and it is consistent to be difficult to the performance that reaches with fuel vehicle.
Summary of the invention: the irrational problem of gravity centre distribution that the objective of the invention is to overcome carrying of chassis in the prior art and car, by changing multi-speed gear box and battery vehicle frame and annexation are set, the hoisting structure that provides a kind of multi-speed gear box and battery all to concentrate on central frame beam satisfies the electrobus chassis special of vehicle performance and safety.
Electrobus chassis special of the present invention, drive motor dynamic assembly, multi-speed gear box, propons, rear driving axle, power battery pack, car load brake system, the power steering system that vehicle frame is arranged and the be arranged on vehicle frame chassis assembly that air-conditioning compressor constitutes of unifying.It is characterized in that: power battery pack is concentrated and is arranged on the mid-support hanger of vehicle frame, and the full car weight heart is concentrated, and when turning, can guarantee the stability of car load.The multi-speed gear box of drive motor dynamic assembly and interlock is arranged on the vehicle frame rear portion, and rearmounted drive motor is passed to rear driving axle to power by many gears change-speed box and transmission shaft and come drive wheels.When the big sloping road of car load ramp angle, alleviate motor by multi-speed gear box and produce noise and heat dissipation capacity when the high pulling torque.Make motor reach when climbing afterwards by speed changer and the strength when quickening with suitable moment of torsion.Thereby the performance figure consistent have been reached with the fuel oil passenger vehicle.This electrobus chassis special adopts power battery pack to install concentratedly under central frame beam and lifts.Make car load at a high speed and when climbing certain sloping road,, can play the effect and the safety of whole vehicle stability like this because the center of gravity of car load is concentrated.Angle of inclination when car load is turned is very little, guarantees passenger's safety to greatest extent.
The present invention compares with existing technology, owing to adopt the electrobus chassis special of such scheme, all has higher tractive performance to export and security and stability when being high speed and full carrying climbing.
