Embodiment Construction
[0027] The structure of the sliding rocker mechanism is as follows image 3 As shown, it is mainly composed of two half shafts, two sliding sleeves, two large bevel gears, a small bevel gear, a shift fork, and a housing, wherein the housing is divided into a left housing and a right housing. the link between them The relationship is: The inside of the sliding sleeves on the left and right sides is connected with the half shafts on the left and right sides through sliding splines, and the outside of the sliding sleeves on the left and right sides is combined with or disengaged from the large conical gears on the left and right sides through sliding splines. The large bevel gears on the left and right sides are meshed with the small bevel gears. The large bevel gears and small bevel gears on the left and right sides are supported on the housing through tapered roller bearings. When working, the sliding sleeve 8 and the sliding sleeve 10 are moved at the same time through the...

The invention discloses a transmission control mechanism capable of realizing forward and reverse reversion and opposite rotation. The transmission control mechanism consists of two half shafts, two slide sleeves, two large bevel gears, a small bevel gear, a poking fork, a shell and a self-locking device; the shell is divided into a left shell and a right shell; the internals of the slide sleeves on the left and right two sides are connected with the half shafts on the left and right two sides through slide splines; the externals of the slide sleeves on the left and right two sides are combined with or deviated from the large bevel gears on the left and right two sides through slide splines; the large bevel gears on the left and right two sides are engaged with the small bevel gear; the large bevel gears on the left and right two sides and the small bevel gear are supported on the shell through bevel roller bearings; the self-locking device consists of a self-locking spring, a self-locking steel ball and a poking fork shaft; the poking fork shaft is connected with the poking fork; three grooves are axially distributed in the upper surface of the poking fork shaft; the self-locking steel ball is embedded in the corresponding grooves of the poking fork shaft under the pressure effect of the self-locking spring; the poking fork shaft is supported in a poking fork shaft hole of the shell; and the self-locking spring is mounted in a spring hole of the shell.
Description
technical field [0001] The present invention relates to a transmission control mechanism, in particular to a transmission control mechanism capable of realizing positive and negative reversing and counter-rotation. , and rotate at opposite speeds, belonging to the technical field of mechanical engineering. Background technique [0002] The vehicle can turn or turn around in a narrow space or on a narrow road by using the in-situ steering device, which can make the vehicle highly maneuverable. The structure of the existing in-situ steering device is relatively complicated, and the efficiency of the device using hydraulic components to realize in-situ steering is relatively low. Moreover, an additional set of devices needs to be added when realizing forward and reverse reversing, which makes the structure more complicated and the cost increases. The present invention is a transmission control mechanism capable of realizing forward and reverse reversing and counter-rotation, ...
