Abstract
The utility model relates to an improvement of a transmission structure, which comprises a box body. The input shaft inside the box body is orderly connected to a variable speed planetary device, an overspeed planetary device and a direction-changing planetary device. The utility model has the characters of simple structure and oil-saving.
Description
The utility model relates to the improvement of speed changer structure.
At present, the automobile of the domestic production overwhelming majority is a hand gear, and its shortcoming is operation inconvenience, and frequent gear shift makes the chaufeur anxiety, fatiguability, and careless slightly driving engine will stop working; In addition, during gear shift, cause that easily the front and back of vehicle body are rocked, people are not felt well, therefore, hand gear will be eliminated with the development of automobile cause.Though and the external automatic transmission with hydraulic torque converter of introducing has good automatic speed changing performance, also there is following shortcoming: be to need the powered change-speed box one,, therefore will fuel consumption, make automobile oil consumption value increase; Can only travel at 1-2 grades in the urban district, rather than economic pace, also make the oil consumption value increase; Two, structure is extremely complicated, makes difficulty, so the cost height.
The purpose of this utility model just provides a kind of simple in structure, the centrifugal automatic transmission with hydraulic torque converter that oil consumption is low.
The purpose of this utility model is achieved in that the utility model comprises casing, and its structural feature is that the input shaft in the casing links to each other successively with variable speed planetary device, hypervelocity planet device, break-in planet device; The sun wheel of variable speed planetary device, clutch hub are individually fixed on the bearing, unilateral bearing of input shaft, casing, and the satellite gear between sun wheel and the clutch hub is provided with by the spring bonded assembly and moves on the pinion carrier of hoof; Turning cylinder on the pinion carrier links to each other with the pinion carrier of variable speed planetary device, and the same respectively sun wheel of the satellite gear on the pinion carrier, wheel hub are meshed, the shift fork that wheel hub is outside equipped with can same wheel hub, pinion carrier, casing internal tooth are meshed; The satellite gear of the pinion carrier that the turning cylinder of sun wheel is outer links to each other with the annular gear with output shaft, sun wheel respectively, the sliding gear collar that annular gear is outside equipped with can same pinion carrier, the casing internal tooth is meshed.
Major advantage of the present utility model:
1, simple in structure:
The utility model mainly is to be provided with variable speed planetary device, hypervelocity planet device, break-in planet device in casing, and therefore, its member is simply more than existing automatic transmission with hydraulic torque converter, is easy to make, and its cost is also low;
2, fuel-economizing:
Because be not by powered change-speed box of the present utility model fully, and rely on centnifugal force that mobile hoof is combined into one with the clutch hub, reach speed changing effect, just saved power, promptly saved fuel oil; In addition, can arbitrarily adjust gear, and not be subjected to the restriction of 1-2 grades of existing automatic transmission with hydraulic torque converters, therefore also save fuel oil in the urban district according to people's needs.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the right elevation of the variable speed planetary device among Fig. 1.
Below in conjunction with accompanying drawing concrete structure of the present utility model is described further:
The utility model comprises casing 1, and the input shaft 26 in the casing 1 links to each other successively with variable speed planetary device 28, hypervelocity planet device 10, break-in planet device 2; The sun wheel 24 of variable speed planetary device 28, clutch hub 20 are individually fixed on the bearing 25, unilateral bearing 22 of input shaft 26, casing 1, and the satellite gear 23 between sun wheel 24 and the clutch hub 20 is provided with by spring 18 bonded assemblys and moves on the pinion carrier 21 of hoof 19; Turning cylinder 17 on the pinion carrier 16 links to each other with the pinion carrier 21 of variable speed planetary device 28, satellite gear 13 on the pinion carrier 16 is meshed with sun wheel 12, wheel hub 14 respectively, and wheel hub 14 is outside equipped with the shift fork 15 that can be meshed with wheel hub 14, pinion carrier 16, casing internal tooth 11; Satellite gear 3 on the outer pinion carrier 7 of the turning cylinder 8 of sun wheel 4 links to each other with the annular gear 6 with output shaft 5, sun wheel 4 respectively, and annular gear 6 is outside equipped with the sliding gear collar 9 that can be meshed with pinion carrier 7, casing internal tooth 11.
Usually, the variable speed planetary device 28 of the change-speed box of car of the present utility model can adopt two, and the variable speed planetary device 28 of the change-speed box of lorry of the present utility model can adopt three.
Below in conjunction with a description of drawings course of action of the present utility model:
When 1, carrying out normal speed change:
During low speed: input shaft 26 rotates, drive satellite gear 23 and rotate (unilateral bearing 22 reverse locking clutch hubs 20 this moment) around clutch hub 20, meanwhile satellite gear 23 drives turning cylinder 17 rotations by pinion carrier 21, passes through hypervelocity planet device 10, break-in planet device 2 again to output shaft 5;
During high speed: input shaft 26 rotates when increasing to certain high speed, pinion carrier 21 turn to make mobile hoof 19 be close to clutch hub 20 and make satellite gear 23 with clutch hub 20 with synchronous rotation.
When 2, exceeding the speed limit:
3, during break-in:
