Embodiment Construction
[0018] As shown in the figure, the gear type automobile automatic transmission mainly includes a coupling, a gearbox, a gear clutch, and an overrunning clutch. The star wheel 21 of the overrunning clutch is fixedly connected to the two shafts 20, and the star wheel 21 is installed in the drum 11. , There are rollers on the star wheel 21, and grooves are arranged on the positions corresponding to the drum 11 on the rollers. The other end of the star wheel 21 is a gear clutch, and the front end of the gear clutch is equipped with a shift fork cover 10 and a shift fork. Thin cylinder 26 is housed on the rear housing 22 of overrunning clutch, and thin cylinder 26 is connected with shift fork. When the speed of the overrunning clutch is lower than the speed of the rear, the engine and the drive axle are cut off.
[0019] The main shaft 1 of the coupler is equipped with a positioning bearing 2, and the positioning bearing 2 is radially installed in the coupling shell 5, and the cyl...

The invention relates to a gear-type automotive automatic transmission which comprises a coupler, a transmission, a gear clutch and an overrun clutch. The gear-type automotive automatic transmission is characterized in that a positioning bear is disposed on a spindle of the coupler, an air cylinder is disposed between the spindle and a casing, a rotatable bevel cam is disposed at one end of a piston inside the air cylinder, the bevel cam is in transitional contact with a parallel cam, the gear clutch is provided with a small key wheel, a large key wheel and a drum wheel, a bearing is disposed on the small key wheel and is fixed to a second shaft, the large key wheel is connected to the small key wheel through keys, the keys are spaced, the large key wheel and the small key wheel slide within a certain range, the keys of the large key wheel are connected with keys on the end face of the drum wheel while the keys are spaced, and two ends of the drum wheel slide within a certain range to allow a gear to conveniently engage or disengage during rotation. The structurally innovated and modified gear-type automotive automatic transmission has the advantages that the coupler and the gear clutch are added to fully replace the clutch functionally, and accordingly full gear engaging and disengaging is achieved for automobiles.
Description
technical field [0001] The invention relates to an automatic transmission for automobiles, in particular to a gear type automatic transmission for automobiles. Background technique [0002] The automatic gearbox of a traditional car uses a wood-chip coupling for speed change. Its transmission power efficiency is not high, and there is an error with the actual output speed. The coupling drive is performed by a high-power torque converter. The automatic transmission car requires high power and high torque. device to complete the hydraulic transmission work. Engine function loss is high, vehicle economy is poor, product structure is complex, manufacturing is difficult and costly. [0003] On November 29, 2007, I applied for an invention patent named "Automotive Fuel-Saving Inertia Sliding Device", the patent number is ZL200710168523.7, this patent can replace the function of some automobile clutches, shifting gears without stepping on the clutch, which simplifies driving The ...
