Embodiment Construction

[0059] Such as figure 1 , figure 2 with image 3 Shown is an embodiment of the two-shaft two-speed transmission of the automatic transmission of the present invention. The gear shaft 1 is assembled in the casing 24 through a bearing 23, and an outer sleeve torque shift mechanism actuator system is installed on the gear shaft. The operating device 9 is that the inner gear ring 5 of the active sleeve 3 is installed on the outer ring groove 4 of the gear shaft in an intermittent sliding fit. The active sleeve is intermittently sleeved on the sliding sleeve 2 through helical teeth, and the sliding sleeve is intermittently fitted with splines. On the gear shaft, the sliding sleeve is fitted between the inner gear ring and the retaining ring 7 provided on the gear shaft. A compressed return spring 8 is installed between the sliding sleeve and the retaining ring, and the return spring is sleeved on the gear shaft. Above, the right end of the sliding sleeve is fixed to the active fram...

Abstract

The invention discloses an automatic speed changer. The automatic speed changer comprises a gear range gear transmission system and a gear shift mechanism execution system and is characterized in that: the gear shift mechanism execution system comprises an operating control device, a reverse action device and a transmission shifting device; the reverse action device comprises a control frame, a driving frame, a driven frame and a spring; the driving frame is elastically connected with the driven frame through the spring; the driving frame and the driven frame are in axial slide fit with the control frame respectively; the slide stroke of the driving frame is larger than that of the driven frame, and the middle point of the slide stroke of driving frame and the middle point of the slide stroke of driven frame are on the same plane; the operating control device can make the driving frame move so as to force the driven frame to reversely move; and the driven frame is moved to make the transmission shifting device force the gear range gear transmission system to shift so as to change the speed. The automatic speed changer has the advantages of high transmission efficiency, variable gear ranges and long service life, can be assembled on various motor vehicles and agricultural machinery and can save power and fuel when used.

Description

Technical field [0001] The invention relates to an automatic transmission for shifting and speed changing in motor vehicle transmission, in particular to a fully automatic shifting and speed changing device for electric vehicles, fuel vehicles, and hybrid vehicles, which belongs to the technical field of mechanical transmission. Background technique [0002] The existing continuously variable automatic transmission has low mechanical efficiency, easy damage, high cost, and unstable performance; the mechanical automatic transmission is large in size, and the shift quality is poor; the hydraulic automatic transmission has low transmission efficiency and is expensive; the mechanical manual transmission is cumbersome, The mechanical efficiency is low and it is not convenient to use. [0003] In the prior art, the Chinese invention patent application (application number: 200910067026.7) discloses an automobile dual-clutch automatic transmission transmission device, which is mainly compo...
