Description

A kind of electrocar chassis
Technical field
The invention belongs to the electric vehicle engineering field, relate to a kind of multifunctional automobile chassis, apply to the high strength chassis of electrocar especially.
Background technology
Along with the progress of expanding economy with science and technology, the recoverable amount of automobile increases year by year, and the performance requriements of automobile is improved constantly, and is that the locomotive of power is serious day by day to the pollution of atmosphere with the combustion engine, and receives the restriction of resource, can't continue existing each item requirement.Original diesel locomotive is only by the maximum Quality Design chassis of carrying; Elec. vehicle is for can improve continual mileage; Increase the electrokinetic cell pool-size and promptly increase the own wt of vehicle chassis,, under the situation of carrying identical number, will increase the vehicle chassis load as still using existing vehicle chassis; Cause safety performance to reduce greatly, shortened the vehicle operation life-span.
As everyone knows, it is also very little to develop the depot of electrocar chassis special at present.And Oversize vehicles such as the First Auto Group of China, Second Automobile Works's east wind enterprise also only just simply gets involved the developmental work of electronic chassis of the minitype automobile at the beginning of 2011, and receives the constraint of engineering factor, and very long following period of time has also been failed than quantum jump.
Existing car all adopts the monocoque skin construction design; Because chassis and vehicle body form an integral body; Make bulk strength increase, so chassis and vehicle body almost all adopt the iron sheet floating screed to form, base plate also just carries out simple laterally reinforcement; If only this is far from being enough as the needed chassis of pure electric vehicle intensity, caused the development difficulty of the battery-driven car chassis special of same level vehicle.
Summary of the invention
The objective of the invention is the position and overcome above-mentioned technical disadvantages, and a kind of innovation structure design-calculated electrocar chassis that proposes.
The present invention mainly is the structure design that on the electrocar chassis ridgepole, has carried out innovation; Made full use of leg-of-mutton characteristic, and adopted the welding of high strength manganese steel rectangular tube in a large number, toughness preferably is provided; Finally the crossbeam assembling by 2 longerons, 1 support beam and 5 different sizes is welded; Not only guaranteed big beam strength but also the electrokinetic cell casing is provided, made total system be integrated, distributed weight uniformly under the vehicle heavy condition; And can be good at bearing the cross side stress that vehicle produces, absorb front, side and 45 degree impacts.
Main technical schemes of the present invention: a kind of electrocar chassis; Comprise vehicle frame and actuating device; Said actuating device comprises drive motor, electric machine controller, change-speed box; Semiaxis, drive front axle is characterized in that said vehicle frame is welded through the different size rectangular tube, absorb collision prevention girders, front apron and middle cross member of frame through front vehicle frame and the back cross member of frame is welded into the whole rectangular tube vehicle frame of bearing-type by left and right single tube longeron and midship mounting beam; Vehicle frame comprises front vehicle frame, middle vehicle frame and back vehicle frame, is welded with the absorption beam on the middle vehicle frame, is welded with reinforced rib between middle vehicle frame and the back vehicle frame, is welded with the triangle reinforced rib on the back vehicle frame.
Usually, front vehicle frame of the present invention is equipped with the drive system assembly that integral body protrudes in vehicle body; Middle vehicle frame is provided with the installation site of electrokinetic cell; Back vehicle frame is provided with and is used to that back axle assembly is installed and back seat is provided and the space of boot.
Vehicle frame of the present invention is the bearing-type unitized frame, is welded through the different size rectangular tube.Can better weight distribution each to vehicle frame being put under the vehicle fully laden, guarantee that vehicle frame is stressed evenly, the life-span of having improved vehicle frame.Because template supports in the connection of each point, guaranteed the cross side stress that vehicle goes and produces under turning and abominable road simultaneously, the injury to whole vehicle frame produces makes vehicle frame be difficult for torsional deflection, increases the service life.The various stress that said vehicle frame can absorb under the specific condition rapidly to be produced.
Front vehicle frame is equipped with the drive system assembly, and integral body protrudes in vehicle body integral body, when making positive bump certain cushion space is arranged, and has guaranteed passenger personnel's safety, makes that the car load design is more reasonable.Middle vehicle frame provides the installation site of electrokinetic cell, has guaranteed the axle load proportioning and the center-of-gravity position of vehicle.Back vehicle frame is mainly used in to be installed back axle assembly and back seat is provided and the boot space.
Compared with prior art, advantage of the present invention:
1. chassis axle can be dealt with the road conditions of urban congestion apart from weak point.
2. cross side stress in chassis is little, uses the chassis indeformable for a long time.
3. the chassis bearing capacity is strong and curb mass is lighter.
4. the chassis electrokinetic cell is put rationally, satisfies the space requirement of battery-driven car.
5. chassis frame is stressed evenly, and driving stability is applicable to hot-short.
6. the chassis travelling comfort is better, and is suitable for various road conditions.
7. adopt four-wheel disc brake system, braking is sensitive, and safety performance is superior.
