Description
Technical field
What the present invention relates to is a kind of testing table, specifically car test bench.
Background technology
In recent years, due to pressure and the prior art level of environmental protection and energy crisis, oneself becomes the focus of automobile industry research hybrid vehicle.As the advantage of hybrid vehicle, regeneration brake system reclaims the portion of energy of automobile on the basis that guarantees brake efficiency and stability, and the economy, the emission performance index that increase continual mileage and raising hybrid vehicle are had great importance.
Regenerative braking is hybrid vehicle sharpest edges aspect energy utilization and environmental protection compared with orthodox car.Hybrid vehicle can save energy 20% after adopting regenerative braking.
The commercialization process of hybrid vehicle is accelerated at present, the blindness of regeneration brake system design when avoiding developing hybrid vehicle, new car is developed and just can make better control and evaluation to the performance of regeneration brake system before, it is very important that the exploitation of the correlative study of hybrid vehicle regeneration brake system and testing table thereof seems.
More current colleges and universities of China and large car enterprise are developing hybrid vehicle, experimental stage under development generally all can be built testing table, especially can embody the regenerative braking testing table of hybrid vehicle advantage, but current the built applied device for power absorption of regenerative braking testing table is all jack horse test bed based on engine dynamometer, and test-bed based on chassis dynamometer yet there are no.
Summary of the invention
The object of the present invention is to provide a kind of hybrid vehicle regenerative braking testing table charger that can reproduce real vehicle driving wheel loaded-up condition.
The object of the present invention is achieved like this:
A kind of hybrid vehicle regenerative braking of the present invention testing table charger, it is characterized in that: comprise stand, the first fixed support, the second fixed support, chassis dynamometer, power assembly is installed in stand, brake system, stand both sides external arranges respectively the first driving wheel and the second driving wheel, the first driving wheel, power assembly, brake system, the second driving wheel is connected successively, the first driving wheel and the second driving wheel below arrange chassis dynamometer, the rotary drum of chassis dynamometer contacts with the first driving wheel and the second driving wheel, the first support bracket fastened two ends fix on the ground, the first support bracket fastened middle part is positioned at the top of stand, the second fixed support is arranged on stand, on the first fixed support, have threaded hole, on the second fixed support, have hole, threaded screw rod is through hole and threaded hole, the lower end of threaded screw rod arranges disk, thereby rotary disk also matches with threaded hole by threaded screw rod and drives the second fixed support to move up and down the variation that can realize stand and be applied to load on driving wheel.
The present invention can also comprise:
1, the second fixed support two ends and stand junction adopt concave design.
Advantage of the present invention is: the present invention designs according to the reality of testing table and chassis dynamometer, there is reliable, the big or small adjustable feature of loaded load of loading, can auxiliary hybrid power automobile regenerative braking testing table true reappearance car load driving wheel load, significant to better realizing regenerative braking.Booster action by charger to hybrid vehicle regenerative braking testing table, has made up the reality that driving wheel load that regenerative braking testing table relative real vehicle parts do not bring entirely and real vehicle are not inconsistent.It is simple in structure, compact that the present invention has, the feature that maintaining is easy.
