Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Referring to Fig. 1, from scheming, can find out, the utility model energy-saving brake device, comprise wheel hub 1 and be connected the main shaft 8 rotating with drive hub with wheel hub, on main shaft 8, be arranged with energy stroage spring 4 and ratchet 10, energy stroage spring 4 two ends are respectively equipped with disk, and near wheel hub is right-hand member disk 3, away from wheel hub be left end disk 7, left end disk 3 is connected to form ratchet device by ratchet with ratchet 10.Be provided with fixture block 2 in wheel hub 1 inner side.On vehicle body, be provided with fixed muffle 5, main shaft 8 passes from fixed muffle 5, and ratchet 10 and two disks are arranged in fixed muffle 5.On fixed muffle 5 inwalls, be provided with two groups of fixed blocks 6, these two groups of fixed blocks 6 are between two disks 3,7 and distinguish corresponding with disk.

This energy-conservation brake gear also comprises the shift fork 9 with brake pedal interlock, shift fork 9 is connected with two disks 3,7 simultaneously, shift fork 9 in the time that brake pedal is stepped on, can promote two disks 3,7 and spring 4 moves toward wheel hub 1 direction, in the time that brake pedal is stepped on stroke and is acquired a certain degree, can make the disk of right-hand member disk 3(near wheel hub) engage with the fixture block 2 on wheel hub, make the disk of left end disk 7(away from wheel hub simultaneously) engage with fixed block 6 corresponding on fixed muffle.Take-off the brake power, when brake pedal resets, shift fork can drive two disks and spring toward moving away from wheel hub direction, and right-hand member disk 3 is engaged with fixed block 6 corresponding on fixed muffle.After above-mentioned engagement occurs, if further deeply step on brake pedal, the shift fork 9 of setting up due to the relevant hydraulic efficiency pressure system of braking and this structure is two-part structure arranged side by side, therefore both are independent of each other, be that brake pedal can continue motion and realizes more effective braking, now shift fork puts in place and no longer moves, and shift fork only has dial-out and reverses two positions and corresponding action, does not affect normal brake.

Described disk is provided with engaging tooth, and fixture block and fixed block are provided with the engaging tooth of corresponding engagement with it.

The utility model energy-saving brake device, utilizes spring potential energy to store the energy of wheel hub decay in brake process, due to the twisting force of spring, has also aggravated braking, and stopping distance is shorter.In decontroling brake, the potential energy that spring stores is by abrupt release, and this potential energy is converted into power driven main shaft and rotates, and propelling vehicle advances.

The utility model principle of work is described below:

One, while brake, shift fork 9 promotes two disks 3,7 and slides to the right, and now, fixture block 2 and right-hand member disk 3 mesh together, and left end disk 7 and left side fixed block 6 engage.Under this state, automotive hub 1 rotates, and drives right-hand member disk 3 to rotate, and right-hand member disk 3 drives energy stroage spring 4 to rotate again, and because left end disk 7 is static, like this, the kinetic energy of wheel hub 1 is just converted into the potential energy of energy stroage spring 4 and stores, and the speed of a motor vehicle slows down or stops.

Two, (being also under normal condition) under releasing of brake, fork 9 is stirred two disks left.Now, right-hand member disk 3 is thrown off with wheel hub 1 and is meshed together with corresponding right side fixed block 6, and left end disk 7 is thrown off with left side fixed block 6 corresponding on fixed muffle simultaneously.Under this state, therefore right-hand member disk 3 is because engage with right side fixed block 6 transfixion, the potential energy that energy stroage spring 4 stores is released, therefore twirl of left end disk 7, because left end disk 7 is connected with main shaft 8 by ratchet device, in the time that main shaft 8 rotating speeds are slower than the rotating speed of left end disk 7, due to the effect of ratchet device, left end disk 7 drives main shaft 8 to rotate, and the potential energy that energy stroage spring 4 stores drives main shaft 8 to rotate by left end disk 7 and ratchet device, thereby realizes the recycling of braking energy; When main shaft 8 rotating speeds are during higher than the rotating speed of left end disk 7, ratchet and ratchet are thrown off, and left end disk 7 no longer drives main shaft 8 to rotate, and is directly rotated by driven by engine main shaft 8 and wheel hub 1, and vehicle enters normal motoring condition.

If brake because stop, now main shaft stops operating due to flame-out, the potential energy that vehicle stop rear spring stores will be preserved owing to cannot promoting main shaft to rotate always, rotate, and the energy of this storage will be conducive to vehicle and start until start main shaft drives wheel hub next time.
