Description
The utility model relates to a kind of braking automobile closed-center system, particularly adapts to the brake closed-center system of bus.
Existing automobile braking device mostly is to adopt friction braking, makes the kinetic energy of automobile become thermal loss and has fallen.For addressing this problem, Canadian national research center and West Germany's Technische University Berlin have all adopted the hydraulic accumulation energy system, can saving fuel about 30%.Sweden VOIVO city motor bus and Britain's LegLand city motor bus have adopted flywheel energy storage system, can saving fuel 25～30%.More than two kinds of system's manufacturing costs higher, must carry out bigger change to former force transferring structure.U.S. Eaton Engineering Research Center is designed a kind of elastic energy storage system, and energy storage efficiency is more than 70%, though simple in structure, low cost of manufacture also must be carried out bigger change to former force transmission mechanism.Very big difficulty takes place in the city motor bus repacking existing to China.
The purpose of this utility model, it is convenient to provide a kind of repacking, low cost of manufacture.Operation control is simple, does not change the elastic energy storage system of original force transferring structure.It can store the kinetic energy of the automobile form with elastic potential energy, uses during the starting of steam supply car.
The purpose of this utility model is achieved in that on the transmission shaft of automobile.Energy of suit becomes elastic potential energy with the moment of torsion of transmission shaft, and the accumulator that can store and discharge at any time.Whole accumulator is that floating bushing is contained on the front propeller shaft of automobile secondary drive shaft.When automobile normal running, accumulator does not influence front propeller shaft work, and this accumulator is connected in series mutually by friction clutch, planet wheel decelerator, elastic energy storage body and housing, and releasing mechanism is connected in parallel between elastic body and the planet wheel decelerator.When braking automobile, often open the friction clutch closure with what connect transmission shaft and planet wheel decelerator, transmission shaft is passed to the elastic body that connects with satellite gear, elastic body twisting energy storage by planet wheel decelerator with moment of torsion.The elastomeric other end is connected with housing.After automobile stopped, elastic body had the effect of replying moment of torsion, made the mono-directional overrun clutch and the transmission shaft locking of releasing mechanism.It is still closed that this drives friction clutch often, exports to the revolution ratio of transmission shaft greater than elastic body by releasing mechanism because transmission shaft inputs to elastomeric revolution ratio, makes the mechanism self-locking take place.After automobile stops like this, can not fall back because of elastomeric answer moment of torsion.When automobile need be started to walk, to throw off as long as will often drive friction clutch, elastic body can be passed to transmission shaft with moment of torsion by releasing mechanism.Work as engine operation, when transmission shaft was active moment, transmission shaft was just thrown off the mono-directional overrun clutch of releasing mechanism, makes whole accumulator disengaging effect.
The utility model only needs to reequip the front propeller shaft of automobile, promptly pulls down front propeller shaft, loads onto the new biography moving axis that has accumulator, and with the housing of accumulator with automotive frame is fastening gets final product.Transmission device originally and brake gear function are constant, so repacking is convenient especially.In operation, because of only needing to grasp the clutch of a friction clutch, (making a comment or criticism to driving) so it is connected on the play motion section work of original footbrake lock, so both can satisfy the holding function of accumulator, can make things convenient for the operating habit of chaufeur again.On manufacturing cost, this repacking is conceived to easy-to-dismount transmission shaft transformation, and does not resemble the transformation of the external closed-centre system point of view in the flywheel and the change speed gear box of driving engine.So the repacking cost is lower, also adapt to the repacking of the existing automobile of China.
Fig. 1 is the closed-centre system diagram of block.
Fig. 2 is the accumulator diagram of gears.
Describe detail of the present utility model and service condition in detail below in conjunction with Fig. 1, Fig. 2.
This accumulator is by friction clutch (4), and several parts of planet wheel decelerator (5), elastic body (6), releasing mechanism (7) and housing (19) are formed.Input torque is that transmission shaft (2) passes through friction clutch (4) closure, drives planet wheel decelerator (5) and elastic body (6) twisting energy storage.Releasing mechanism (7) is connected in parallel between planet wheel decelerator (5) and the elastic body (6).In energy storage when work,, because mono-directional overrun clutch (7) rotating speed of releasing mechanism (7) is less than the rotating speed of transmission shaft (2), releasing mechanism (7) discord transmission shaft (2) is had an effect.After automobile stops, elastic body (6) has the answer torsional interaction, gear (18) drives planet bar (12), satellite gear (15) idle wheel (14), gear (13), locks through mono-directional overrun clutch (16) and transmission shaft (2), and and the effect of the back one-level satellite gear (11) of planet wheel decelerator (5), to transmission shaft (2) output torque, the answer moment of torsion of elastic body (6) passes through friction clutch (4) to transmission shaft (2) output torque with secondary planet wheel speedup again simultaneously with the one-level speedup.Because there is speed discrepancy in mechanism, and the answer twisting power of elastic body (2) is self-locking in the housing (19).During vehicle starting, friction clutch (4) is thrown off, and the answer moment of torsion of elastic body (6) is passed to transmission shaft (2) through releasing mechanism (7).During automobile normal running, whole accumulator floating bushing is contained on the transmission shaft (2), and housing (19) is fastened on the automotive frame, can replace the central support effect of former secondary drive shaft.
Friction clutch (4) can be electromagnetic friction clutch, also can adopt the friction clutch of mechanical type and fluid pressure type, the first order center gear (8) of friction clutch (4) and planet wheel decelerator (5) is connected, center gear (8) drives three satellite gears (9), first order planet bar and second stage center gear (10) are one, center gear (10) drives four satellite gears (11) again, the gear (17) of second stage planet bar (12) is connected with the gear (18) of three elastic bodys (6), the elastic body (6) that six neoprene are made is a pair of series with two, and it is that sliding sleeve gear (20) by gear of elastic body (6) (21) and housing (19) one ends is cascaded.The other end of elastic body (6) and housing (19) are fixing.As housing (19) length need can, also available torsion spring is made elastic body (6).Sliding sleeve gear (20) can and gear (21) throw off.Have on planet bar (12) and satellite gear (11) is connected on one satellite gear (15), this satellite gear (15) drives idle wheel (14) gear (13) and drives mono-directional overrun clutch (16) again.When reversing automobile, at this moment the counter-rotating of transmission shaft (2) and mono-directional overrun clutch (16) locking must push sliding sleeve gear (20) to the right, make elastic body (6) idle running and not energy storage.The control of cliding gear (20) can and change speed gear box (1) backward gear series connection.Like this, when automobile is just travelling, as long as the clutch of control friction clutch (4) just can be finished brake, energy storage, exergic function.And the control and the footbrake plate of friction clutch (4) can be cascaded, make its play motion section work at stretcher.
