This invention relates to an auto transmission energy booster for use in the vehicles. It is known in the art to provide a gear box coupled to the engine through the cluch system to obtain different speed of the vehicle as per the requirement by the driver. The gear boxes used are for example sychnromesh gear box, constant sliding mesh gear boxes, pneumocyclic or epicyclic gear box. A transmission booster disclosed in the patent no. 162739 for use between the output shaft of the conventional gear box and the transmission shaft of said vehicle comprises a booster housing having an input and output shaft disposed therein. A pinion or driving gear is provided at the inner end of the input shaft and is connected to a first driven step up gear mounted on a counter/lay shaft a first drive gear is mounted on the lay shaft and drivingly connected to a low ratio gear mounted on the output shaft. A second drive gear is mounted on said lay shaft and is connected drivingly to a high ratio gear mounted on the output shaft. A sliding dog clutch mounted in the housing for engaging at any one instance said low ratio gear or the high ratio gear with the output shaft. Bearing are provided in the said housing for supporting said counter/lay shaft within the housing. Partition wall is provided in the housing for supporting the input shaft and the lay shaft. There are disadvantages associated with transmission booster as such known in the art. One of the main disadvantage is that the outer bearing of the pinion shaft is failed due to lack of lubrication. Yet another disadvantage is that due to the partition wall provided in the housing between the input shaft and output shaft the accessbility to repair the device is cumbersome and difficult. Still another disadvantage is that the device is very heavy. Another disadvantage is that the firm fitting of the gears on the couter shaft produces noise and wear and tear to the gears is more. Yet another disadvantage is that no means are provided to keep the zero error in the alignment of input and output shaft which is required to keep the zero error in the alignment of these shaft. Still another disadvantage is that no means are provided with the booster to show that the vehicle is running at a high ratio condition unnecessarily. Therefore the main object of this inventiron is to provide an auto transmission energy booster having oil feeding means to the outer bearing of the input shaft by driling the oil feeder passage in the main housing and outer bearing housing for the supply of the lubrications oil to the outer bearing of the input shaft. Still another object of this invention is to provide an auto transmission energy booster and wherein the partition wall togetehr with the middle bearings has been totally eliminated. Another object of this invention is to provide an energy booster wherein the gears are provided on the counter/lay shaft on spilens with spacers provided between the gears. Yet another object of this inventin is to provide a booster having spigot fitment provided within the housing to support the inner ends of the input and output shafts. Another object of this invention, is to provide male and female means to support the inner end of the input and output shaft independantly.

In accordance with this invention an auto transmission energy booster has an input and output shafts disposed in a housing rotatably. A ... pinion/driving gear having a stopper coller integral to it is secured at the inner end of the input shaft. The pinion gear is adapted to be engaged with a step up driven gear splined fitted on the counter/lay shaft. Specifically according to this invention means such as splashed oil collection and feeding scoop is provided with the top cover of the booster housing such that to provide the lubricating oil supply to the bearing provided for supporting the outer end of the input shaft through the oil feeder passages. Further a spigot bearing arrangement is provided between the mating ends of the input and the output shaft to keep such shaft in the alignment and rotation of the shafts independently. An air breather is provided with the top cover of the boosters housing. Further the partition wall provided between the gears has been eleminated according to this invention. Further a synchronizer has been provided between the low ratio and high ratio gears fitted on the output shaft in a floating rotationship to get high speed and the low speed of the vehicle respectively. Signal means are provided to give warning to the driver regarding the unnecessary running of the vehicle in the high ratio condition.
