Abstract

In a normal braking sequence the kinetic energy of a motor vehicle is irreversibly converted into heat. By means of a mechanical (coil spring) or pressure storage device, some of this energy can be optimally fed in by mechanical or pneumatic means to then be utilised in starting. The spring energy is released to the mechanical energy storage device so that, by means of a locking pawl and an equal-sided coupling, the spring relaxation direction = direction of rotational travel. When starting the pressure energy is drawn from the pressure storage device, to which the internal combustion engine has functioned as a compressor during the braking period, in such a manner that the compressed working medium (exhaust gases or air) is fed into the intake pipe. Compression in the cylinder chambers is avoided by control of the outlet valves. <IMAGE>

Description

Energierückgewinnung während eines Brems-Anfahrvorgangs eines Kraftfahrzeugs mit hilfe mechanischer oder pneumatischer Energiespeicher.Energy recovery during a braking start-up process Motor vehicle with the help of mechanical or pneumatic energy storage.

Die Erfindung betrifft einen mechanischen bzw. einen pneumatischen Energiespeicher wie in Anspruch I bzw. 2 dargelegt ist, der während der Bremszeit mechanisch (Spiralfeder) bzw pneumatisch (Druckbehälter) Energie speicht und diese für das Anfahren dann verwendet wird (Rückgewinnung).The invention relates to a mechanical or a pneumatic Energy storage as set out in claim I or 2 is that during the braking time mechanically (coil spring) resp pneumatic (pressure vessel) stores energy and this for the start-up is then used (recovery).

Der Erfindung liegt die Aufgabe zugrunde diese Energierückgewinnung im Stadtverkehr, insbesonderen für die Stadtbusse in die Praxis zu verwerten.The invention is based on the task of this energy recovery in city traffic, especially for city buses to use in practice.

Die mit der Erfindung erziehlte Vorteile, daß unmittelbar mit Energie-Ersparung und einer geringeren Umweltbelastung verbunden sind, ist einwandfrei zu ersehen.The advantages achieved with the invention that immediately with Energy saving and a lower environmental impact are clearly visible.

Ob diese Art der Energierückgewinnung nicht als Alternative, für die zur Zeit angewandten Art (Schwungrad-Girobusse, Hydrostatisch- Hydrobusse) sich erweist, muss die Praxis entscheiden.Whether this type of energy recovery is not an alternative, for the type currently used (flywheel giro buses, hydrostatic Hydrobuses), practice must decide.

Für den mechanischen Energiespeicher wird gemäß der Zeichnung näher erläutert:For the mechanical energy storage is according to the Drawing explained in more detail:

Die Spiralfeder (3), daß in der Drehscheibe (2) ein Ende anhaftet, und mit hilfe einer Anhaltscheibe (5) und des Keils (6) die Drehung der Welle (4) (wo das andere Ende anhaftet) verhindert wird, wird aufgezogen und gespannt: da während der Bremszeit die Rotationsscheibe (I) mit Drehscheibe gekoppelt ist. The coil spring ( 3 ), that one end sticks in the turntable ( 2 ), and with the help of a stop disk ( 5 ) and the wedge ( 6 ) the rotation of the shaft ( 4 ) (where the other end sticks) is prevented, is wound and excited: because during the braking time the rotating disc ( I ) is coupled to the rotating disc.

Beim Anfahren, Rotations- und Drehscheibe werden entkoppelt, Sperrklinke (7) rastet in der Drehscheibe ein und verhindert so die Entspannung in entgegengesetzter Drehrichtung. Die Welle beginnt sich zu drehen, mit hilfe einer gleichseitigen Kupplung (8) wird die Federenergie an der Rotationsscheibe übertragen und so rückgewonnen.When moving off, the rotating and rotating disks are decoupled, the pawl ( 7 ) engages in the rotating disk and thus prevents relaxation in the opposite direction of rotation. The shaft begins to turn, with the help of an equilateral coupling ( 8 ) the spring energy is transferred to the rotating disc and thus recovered.

Für den pneumatischen Energiespeicher sind 4 Arbeitsphasen charakteristisch und werden an hand der Skizze darunter erläutert;
A - Normalbetrieb (Fahrt): Ventil I, 2, 3 auf.
B - Speichen (Bremsen): Ventil I auf, 2 zu, 3 auf oder zu.
C - Rückgewinn (Anfahren): Ventil I zu, 2 auf, 3 ohne Einfluß
D - Beschleunigung: wie Phase A-. RV - Zusatzregelung der Ablaßmotorventilen in der Phase C -; wird dadurch Verdichtung in den Zylinderräumen verhindert. Wenn Ventile I und 2 auf bzw. zu, sind für Druckspeicher zu bzw. auf.Four working phases are characteristic for the pneumatic energy storage and are explained using the sketch below;
A - Normal operation (travel): Valve I, 2, 3 open.
B - spokes (brakes): valve I open, 2 closed, 3 open or closed.
C - Recovery (start-up): Valve I closed, 2 open, 3 without influence
D - acceleration: like phase A-. RV - additional regulation of the drain motor valves in phase C -; This prevents compression in the cylinder rooms. If valves I and 2 are open or closed, the pressure accumulator is closed or open.
