Abstract:
An automobile transmission device, comprising:a transmission shaft with its front end linked to the power source of a vehicle, and with its rear end installed with a said reducer gear assembly;an input shaft, with its front end installed with a preposed reducer gear assembly which is engaged with the said reducer gear assembly integral with the transmission shaft, behind said preposed reducer gear assembly there are mounted three input gears, whereof the first input gear is fitted directly onto the input shaft, the second input gear fitted and hooded onto the same input shaft, whereas the third input gear is fitted and hooded onto a sleeving formed as an extension of the second input gear;a first spring-like unit mounted between the input shaft and the sleeving formed as an extension of the second input gear, with its front end locked to said input shaft with a fix pin by way of the sleeving which is in the form of an extension of the second input gear, and with that portion of the input shaft on the rear end thereof fitted with an adaptor whose front end is lapped to said first spring-like unit by ratchet fronts provided thereon, a fix pin being mounted between said adaptor and the input shaft, on that portion of the input shaft behind the said adaptor there is locked a stop nut, on the perimeter of said adaptor there is mounted a hooded pusher sleeve whose front end abuts upon the outermost annular surface of the ratchet front of the said first spring-like unit, and the periphery of said pusher sleeve is wound with a spring;a second spring-like unit lying between the sleeving formed as an extension of the second input gear and a sleeving formed as an extension of the third input gear, with its front end locked to the sleeving that is an extending part of the second input gear, with a fix pin, by way of the sleeving that forms an extending part of the third input gear, on the input shaft behind the second spring-like unit there is provided an adaptor whose front end forms an overlapping relation with an exposed surface of the second spring-like unit due to the presence of ratchet fronts on both components, said adaptor and the sleeving that forms an extending part of the second input gear are interrelated to each other by a fix pin, with respect to the rear side of said adaptor there is a stop nut, on the perimeter of said adaptor there is mounted a hooded pusher sleeve whose front end abuts upon the outermost ring of the ratchet front of the second spring-like unit, the perimeter of said pusher sleeve there is wound with a spring;a speed regulation disk, mounted and hooded on the farthest end of the input shaft, and in respect of which the angle of rotation is controlled by a revolving lever, said disk is divided into three cells each furnished with a rolling bead on an inner ring, another on an outer ring, both beads being concentrically aligned with said speed regulation disk, and respectively abutting upon the rear side of the second spring-like unit, each cell being further furnished with four grooves to accommodate said rolling beads, whereof the first groove lies on the leftmost position of the inner ring, the second groove lies on the rightmost position of the inner ring, shifted leftwards to leave a spacing for two rolling beads lining up side by side, the third groove lies on the rightmost position of the outer ring, the fourth groove lies on a position at a distance of one rolling bead deviating to the left of the third groove, all these grooves gradually emerging onto the surface of speed regulation disk in the direction in which the rolling beads are guided so that all and each rolling beads may smoothly enter an exit of the grooves;a speed differentiator of which the outer casing is furnished with a gliding sleeve inner rim is engaged with the outer casing of the speed differentiator so that the gliding sleeve may carry the speed differentiator into rotation whereby transmission of power is made, on either side of the gliding sleeve there is provided a gear assembly, said sleeve is linked to a control rod serving to carry the sleeve to glide about on the outer casing of the speed differentiator whose output end on both sides extends and each is equipped with an output shaft, whereof the output shaft on the front end is equipped with three hooded output gears to form a close engagement with three input gears;a planet gear, hooded on assembly and as mounted on the output shaft behind said three output gears, being a solar gear, it is linked with an intermediate transmission shaft provided as an extension of said three output gears, the perimeter of said planet gear is an inner annular gear, said solar and said inner annular gear gears engaged with each other by a number of asterisk gears, a lid is provided as a sleeve on the front end, another on rear end of said planet gear, both lids interlocked with each other with a positioning shaft across each asterisk gear, the perimeter of the front end lid extending to a point outside the inner annular gear, a braking device being provided on said front end, another on the exterior side of the inner annular gear, the perimeter of the rim of said rear end lid being furnished with a face gear, the extended end of the inner annular gear being provided with an edge gear which, together with the face gear on the rear end lid, residing on either end of the gliding hood transit space, can be matched with the gear assembly on said gliding hood.
