TH19283B - Tongue activation system in internal combustion engines - Google Patents

Abstract

DC60 (22/03/44) in the valve actuation system in the internal combustion engine. A piece of The adjacent tongues were provided with first and second support walls. Where the secondary wall The second receiver is placed on the side of the bell, another piece of the tongue pressed and the roller is arranged between the walls. First and second supports for rolling contact with the cam Supported cylindrical roller shaft The roller is so that it can rotate It is provided between the first and second support walls, so the commutator bolts of the corresponding actuator can be assembled properly. It can slide into the roller shaft in response to the movement of the pin to the corresponding working position. The roller shaft is pressed into the second support wall of the first support wall and at the Two is the minimum and press-assembly allowance for the pressed roller shaft. Into the second supporting wall, on the side of the bellows, the other is set less than the tolerance In the assembly press for the roller shaft that is pressed into the second support wall on the roller side, so the roller shaft that supports the roller can be fixed and the commutator pin is attached to the bellows. Tongue more easily While an increase in the number of parts is inevitable. And the increase of Number of operation steps to generate, moreover, during the movement of the bolts switch to Relative working position It can inhibit the shape of the shaft end. The roller that accepts the turning pin for a minimal compression. Which makes there a smoothness of Assembly of the commutator pin in the roller shaft To make the switch between work Relate to the adjacent tongue depressions and relative terminations by the chopping pins The transition is smooth. In the system of activating the tongue in the internal combustion engine A piece of The adjacent tongues were provided with first and second support walls. Where the secondary wall The second receiver is placed on the side of the bell, another piece of the tongue pressed and the roller is arranged between the walls. First and second supports for rolling contact with the cam Supported cylindrical roller shaft The roller is so that it can rotate It is provided between the first and second support walls, so the commutator bolts of the corresponding actuator can be assembled properly. It can slide into the roller shaft in response to the movement of the pin to the corresponding working position. The roller shaft is pressed into the second support wall of the first support wall and at the Two is the minimum and press-assembly allowance for the pressed roller shaft. Into the second supporting wall, on the side of the valve, the other layer is set less than the tolerance In the assembly press for the roller shaft that is pressed into the second support wall on the roller side, so the roller shaft that supports the roller can be fixed and the commutator pin is attached to the bellows. Tongue more easily While an increase in the number of parts is inevitable. And the increase of Number of operation steps to generate, moreover, during the movement of the bolts switch to Relative working position It can inhibit the shape of the shaft end. The roller that accepts the turning pin for a minimal compression. Which makes there a smoothness of Assembly of the commutator pin in the roller shaft To make the switch between work Relate to the adjacent tongue depressions and relative terminations by the chopping pins The transition is smooth.
