Abstract

The utility model relates to a five-shift driven gear device for a speed variator for a car, which set five shifts on the speed variator for the car having small discharge, the central distance is form 54 mm to 59 mm. The five-shift gear ratio is smaller than 1, and the five shifts are positioned in a back casing and behind a reverse shift. After arranged on a reverse driven gear, the five-shift driven gear is sheathed on an output shaft, and a synchronizer assembly is arranged between the two gears. The five shifts adopt synchronous geared rings. The utility model is characterized in that the five-shift driven gear part of the speed variator adopts a two-section lining (2) and a bearing lining (5), wherein the bearing lining (5) is in step type, and the part having bigger step diameter extends into an inner hole of the five-shift driven gear (6). A ball bearing (1) and the five-shift driven gear (6) are divided by a slot washer (3) between them. The utility model has the advantage that the speed variator realizes five shifts by adopting the structure.

Description

Five grades of driven gear devices of automotive transmission
Technical field: the utility model relates to automotive transmission, is specially five grades of driven gear devices of a kind of automotive transmission.
Background technique: automotive transmission commonly used at present comprises casing, input shaft, output shaft, jack shaft, several gear pairs, synchronizer and release bearing operating mechanism.Input shaft carries out the power input; The gear that several can pivot is housed on the output shaft, exports as power.Needle bearing is equipped with on the top of output shaft, and needle bearing is packed in the input shaft stomidium, and input shaft and output shaft are on same axis but be not connected mutually.The axis of jack shaft and the parallel axes of input and output shaft.The reducing sleeve tooth of synchronizer is contained between output shaft two adjacent teeth wheel, the synchronizer external toothing under the shift fork effect, can with the synchronous gear ring of adjacent gear in conjunction with, separate.Yet under the centre distance situation less less than 59mm, overall structure, speed changer can only adopt the form of four forward gearss.The car load of its coupling is difficult for satisfying oil consumption and the noise of country about car load.
Summary of the invention: the purpose of this utility model is less in centre distance, provides a kind of simple in structure, with low cost on the speed changer of housing structure compactness, five grades of driven gear devices that noise is little.The purpose of this utility model is achieved in that it comprises ball bearing (1), lining (2), open washer (3), needle bearing (4), bearing sleeve (5), five grades of followers (6).Five grades of followers of speed changer are two-part linings, are lining (2), bearing sleeve (5); Bearing sleeve (5) is a step type, and the part that its stepped diameters is big extend in five grades of followers (6) endoporus; Adopt open washer (3) to separate between ball bearing (1) and the five grades of followers (6).The utility model has the advantages that simple in structure, with low cost, the housing structure compactness, noise is little.Can improve car load noise and Economy.
Description of drawings: Fig. 1 is the utility model structural principle schematic representation; Fig. 2 is the utility model bearing sleeve structural principle schematic representation; Fig. 3 is the utility model open washer structural principle schematic representation.
Embodiment: five grades of followers of speed changer are two-part linings, are lining (2), bearing sleeve (5); Bearing sleeve (5) is a step type, and the part that its stepped diameters is big extend in five grades of followers (6) endoporus; Adopt open washer (3) to separate between ball bearing (1) and the five grades of followers (6).Five grades of driving gears are enclosed within the rear portion of intermediate gear shaft, assemble elastic washer and bearing successively in its back; With its endoporus assembling needle bearing (4) of five grades of followers (6) of five grades of driving wheel pairing work, needle bearing (4) is enclosed within on the lining (2), and this lining then is enclosed within on the output shaft; Ball bearing lining (5) is assembled on the output shaft; Go up assembling packing ring (3) back assembling ball bearing (1) at ball bearing lining (5).At the place ahead of five grades of followers (6) assembling synchronizer assembly and synchronous gear ring.When its gear is achieved in that five grades, reverse shift fork slides the external toothing of synchronizer assembly to the right, combine by the spline of synchronous gear ring with five grades of followers (6), input shaft is given transmission of power on jack shaft with its normal engagement by gear, jack shaft is given five grades of driving gears with transmission of power, five grades of driving gears pass to synchronizer with power by five grades of followers (6) again, and synchronizer is given output shaft by the reducing sleeve tooth with transmission of power, reach the purpose of five grades of rotating speeds of output.

Claims (1)

1, five grades of driven gear devices of a kind of automotive transmission, it comprises ball bearing (1), lining (2), open washer (3), needle bearing (4), bearing sleeve (5), five grades of followers (6), it is characterized in that: five grades of followers of speed changer are two-part linings, are lining (2), bearing sleeve (5); Bearing sleeve (5) is a step type, and the part that its stepped diameters is big extend in five grades of followers (6) endoporus; Adopt open washer (3) to separate between ball bearing (1) and the five grades of followers (6).
