Раскрытие изобретения Disclosure of invention
Изобретение решает задачу бесступенчатого изменения крутящего момента, передаваемого от источника крутящего момента к потребителю крутящего момента. Данная задача решается за счет того, что бесступенчатая трансмиссия состоит из корпуса с находящимися внутри его элементами конструкции, двух валов (входной и выходной), вариатора с двумя валами и планетарной передачи. При этом один из валов трансмиссии представляет собой единое конструктивное целое с валом вариатора и на нем жестко закреплена шестерня, которая входит в зацепление с другой шестерней, установленной с возможностью осевого вращения в корпусе, которая входит в зацепление с коронной шестерней планетарной передачи. Коронная шестерня планетарной передачи выполнена с внешним и внутренним зацеплением, солнечная шестерня соединена со вторым валом трансмиссии, а водило соединено со вторым валом вариатора. Конструкция является обратимой, в том смысле, что крутящий момент можно подавать на любой из валов трансмиссии. The invention solves the problem of stepless change of the torque transmitted from the torque source to the torque consumer. This problem is solved due to the fact that the continuously variable transmission consists of a housing with structural elements inside it, two shafts (input and output), a variator with two shafts and a planetary gear. In this case, one of the transmission shafts is a single structural unit with the variator shaft and a gear is rigidly fixed on it, which engages with another gear installed with the possibility of axial rotation in the housing, which engages with the ring gear of the planetary gear. The crown gear of the planetary gear is made with external and internal gearing, the sun gear is connected to the second shaft of the transmission, and the carrier is connected to the second shaft of the variator. The design is reversible, in the sense that torque can be applied to any of the transmission shafts.
Техническим результатом предлагаемого изобретения является расширение арсенала бесступенчатых трансмиссий. The technical result of the invention is the expansion of the arsenal of continuously variable transmissions.
Краткое описание чертежей Brief description of the drawings
На чертеже изображена принципиальная схема бесступенчатой трансмиссии с вариатором. The drawing shows a schematic diagram of a continuously variable transmission with a variator.
Осуществление изобретения Implementation of the invention
Бесступенчатая трансмиссия с вариатором состоит из корпуса ( 12), двух валов (1, 9), вариатора (10) с двумя валами (4, 6) и объединяющей их планетарной передачи (11). На одном из валов (1) трансмиссии, представляющим из себя единое конструктивное целое с одним из валов (4) вариатора, жестко закреплена шестерня (3), которая входит в зацепление с другой шестерней (2), установленной в корпусе (12) с возможностью осевого вращения. Шестерня (2) входит в зацепление с коронной шестерней (5) планетарной передачи (1 1), водило которой (8) соединено со вторым валом вариатора, а солнечная шестерня (7) соединена со вторым валом (6) трансмиссии (10). Коронная шестерня (5) выполнена с внутренним и внешним зацеплением. A continuously variable transmission with a variator consists of a housing (12), two shafts (1, 9), a variator (10) with two shafts (4, 6) and a planetary gear (11). On one of the shafts (1) of the transmission, which is a single structural unit with one of the shafts (4) of the variator, a gear (3) is rigidly fixed, which engages with another gear (2) installed in the housing (12) with the possibility axial rotation. The gear (2) engages with the ring gear (5) of the planetary gear (1 1), the carrier of which (8) is connected to the second shaft of the variator, and the sun gear (7) is connected to the second shaft (6) of the transmission (10). Crown gear (5) is made with internal and external gearing.
Изобретение работает следующим образом. Крутящий момент от источника крутящего момента подается на входной вал трансмиссии (1). На шестерне (3) происходит разделение крутящего момента, часть момента попадает на входной вал (4) вариатора, а часть момента попадает через шестерню (2) на коронную шестерню (5) планетарной передачи (И). Далее момент бесступенчато изменяется в вариаторе (10) и через выходной вал вариатора (6) попадает на водило (8) планетарной передачи (11). Коронная шестерня (5) и водило (8) при этом вращаются в одну сторону, крутящий момент суммируется и через солнечную шестерню (7) поступает на выходной вал трансмиссии (9). The invention works as follows. The torque from the torque source is applied to the transmission input shaft (1). On the gear (3), the torque is divided, part of the torque goes to the input shaft (4) of the variator, and part of the torque goes through the gear (2) to the ring gear (5) of the planetary gear (I). Further, the moment changes steplessly in the variator (10) and through the output shaft of the variator (6) enters the carrier (8) of the planetary gear (11). The crown gear (5) and carrier (8) rotate in the same direction, the torque is summed up and through the sun gear (7) enters the output shaft of the transmission (9).
