Abstract

The device has a ratchet wheel (T1) for transmission of rotational movement of engine into a gear box of car in a direction and not in a reverse direction. The rotation movement of the engine reaches a gear (1) against a clock direction and another gear (2) in the clock direction. The rotation movement of the engine is transmitted during an engagement of the wheel with a third gear (4). The ratchet wheel turns in opposite direction by of pullback of the car without resisting the rotation of the engine.

Description

Description Cette innovation empêche l'arrêt du moteur de la voiture si la voiture est en train de reculer à cause de l'inclinaison de la route. Si la voiture se trouve sur une oblique, la gravité de la voiture va causer le mouvement vers le bas de la route pendant l'engagement de la première vitesse pour avancer avec la voiture. La gravité de la voiture va résister à la tentative de rouler vers l'avant ; cette résistance peut causer l'arrêt du moteur, ce que arrive avec les conducteurs non te expérimentés. Cette innovation met une solution à ce problème en utilisant une roue à rochet de type à engrenage dans la boîte de vitesse. Voir la figure ( 1), qui montre l'évolution des engrenages dans une boite de vitesse en cas d'engagement de la première vitesse de la voiture. (Ti) est caractérisé par le fait qu'il tourne avec efficacité dans un sens (il transmet le mouvement de rotation) et tourne dans la direction opposée sans efficacité, c'est à dire, sans transmission de mouvement de rotation. Le mouvement de rotation du moteur arrive à l'engrenage (1) contre le sens horaire et arrive pour l'engrenage (2) avec le sens horaire, puis à l'engrenage (Ti) avec le 2.0 sens horaire, qui transmet le mouvement de rotation en cas d'engagement de la première vitesse à engrenage (4), qui tourne dans le même sens du mouvement de rotation d'entrée du moteur à engrenages (1) soit contre le sens horaire avec une vitesse de rotation moins importante vers les roues de la voiture. Si la voiture dans cette situation commence à faire marche arrière, 25 l'engrenage (4) va tourner avec le sens horaire, la roue à rochet (Ti) ne va pas transmettre ce mouvement de rotation, parce que la rotation contre le sens horaire est non efficace, et dans ce cas, cela n'aura aucune incidence sur la rotation du moteur qui ne s'arrêtera pas, et continuera à tourner malgré le recul de la voiture vers l'arrière.Description This innovation prevents the engine from stopping if the car is backing up because of the incline of the road. If the car is on an oblique, the gravity of the car will cause the movement down the road during the engagement of the first gear to advance with the car. The gravity of the car will withstand the attempt to roll forward; this resistance can cause the engine to stop, which happens with non experienced drivers. This innovation solves this problem by using a gear-type ratchet wheel in the gearbox. See Figure (1), which shows the evolution of gears in a gearbox in case of engagement of the first speed of the car. (Ti) is characterized in that it rotates efficiently in one direction (it transmits the rotational movement) and rotates in the opposite direction without efficiency, that is, without transmitting rotational motion. The rotational movement of the motor reaches the gear (1) counterclockwise and arrives for the gear (2) clockwise, then to the gear (Ti) with the 2.0 clockwise, which transmits the movement of rotation in case of engagement of the first gear gear (4), which rotates in the same direction of the input rotational movement of the gear motor (1) against the clockwise direction with a lesser rotational speed to the wheels of the car. If the car in this situation starts to reverse, the gear (4) will turn clockwise, the ratchet wheel (Ti) will not transmit this rotational movement, because the rotation against the clockwise direction is not effective, and in this case, it will not affect the rotation of the engine will not stop, and will continue to turn despite the rearward of the car.
