Working principle
Unlike ordinary brake system, the present invention utilizes law of conservation of energy, designs moveable cell packet module Structure, part kinetic energy when by emergency brake of vehicle are converted into mechanical energy fast storage, are sustained away after a stop of the vehicle, reduce Vehicle brake undertakes burden that kinetic energy is converted to thermal energy, improves brake service life, fast implements braking energy conversion.
When car speed is higher than 30km/h, apparatus of the present invention start to start, lock device unlock;When the vehicle is braked to vehicle Be force analysis: the braking moment for the generation that rubs between ground and wheel passes to vehicle chassis, and cell packet module is by machinery The opposite force of accumulator, restorer, and generate the braking power of W.At this point, the kinetic energy of cell packet module is E;Braking power is W, As E >=W, cell packet module starts compressor mechanical accumulator and restorer;
After vehicle stops, restorer will push cell packet module to be returned to initial position, this some mechanical can pass through peace Strigil in lifting lug converts thermal energy for the mechanical energy of storage and discharges, due to being provided with single direction ratchet in lifting lug, Strigil does not do work when battery pack starts to travel forward, and when restorer pushes cell packet module to return, strigil starts to do work;
Original state is as shown in fig. 7, the spring 506 in mechanical energy accumulator 5 is in free state, and lock device 7 is by power electric Pond packet module 4 is locked at initial position;When brake apparatus is started to work, lock device 7 is opened, and power battery pack module 4 is certainly Relative motion, and the forward slip in glide path 2 and sliding way 9 are generated under the action of body kinetic energy with vehicle chassis 3, lifting lug 6 is sent out Life is freely rotated, and starts to compress restorer 8 and mechanical energy accumulator 5, state is as shown in Figure 8.After the completion of braking, in restorer 8 Under effect, starts propulsion power cell packet module 4 and restore to original state, due to the work of pawl groups of springs 604 in ratchet 603 With, ratchet 603 and braking brake pad 605 no longer rotate, and pulley 602 rubs when being moved back with braking brake pad 605, Until power battery pack module 4 returns to original state, lock device 7 starts, and braking process is completed.
It is converted by above-mentioned energy, extends energy conversion time, reduce vehicle in emergency braking, braking power Height, the long problem of braking distance.
Mechanical energy accumulator, lifting lug quantity in the present invention can be adjusted according to different complete vehicle qualities and battery pack volume, still Belong in the scope of this patent.The present invention is to release the kinetic energy conversion spring mechanical energy storage of power battery pack module again It puts, mechanical energy accumulator can also be changed to the energy storage devices such as hydraulic energy, electric energy, still fallen in the scope of this patent.
