Bidirectional drive orienting output wheel

Abstract

The invention relates to two-way drive technology, in particular to a two-way drive directional output wheel, which has an output shaft, a ratchet mechanism, and a wheel body, and a first compound gear (6) and a second compound gear (11) are relatively arranged on the output shaft (5) One side of the first and second compound gears (6, 11) is respectively provided with conical teeth, the tooth surfaces are opposite, and its inner wall is respectively matched with the output shaft (5) through a symmetrical ratchet mechanism, and the first and second compound gears (6, 11) 11) Conical gears (8) are installed between them, and the bevel gears (8) mesh with the first and second composite gears (6, 11) respectively, and one end of the wheel body (13) coaxial with the output shaft (5) is connected to the first A composite gear (6) is connected, and a fixed cylinder (12) is installed between the inner wall of the other end and the outer edge of the second composite gear (11), which are rolling fits with each other. The invention can realize that the output end of the upper-level device will rotate in a fixed direction when it is driven in two directions, forward or reverse, and has wide application in various mechanical equipment.

Description

technical field [0001] The invention relates to bidirectional drive technology, in particular to a bidirectional drive directional output wheel. Background technique [0002] In the known transmission mechanism of the wheel train, when the driving direction is reversed, the moving direction of the output end is also reversed, or the output end cannot be driven to move. Such as a bicycle flywheel, there is a shaft on the driving sprocket, and there are two pedals at both ends of the shaft. The shaft is installed in a fixed bushing on the frame and can rotate. The pawl sprocket is supported by the frame. The center of the rear wheel is connected to the drive sprocket through an endless chain. A ratchet mechanism, that is, a one-way clutch, is installed on the pawl sprocket to transmit the positive rotation force of the drive sprocket to the rear wheel shaft, that is, The user can sit on the seat and hold the handlebar with both hands, and then step on the pedal to rotate the ...

Such as a bicycle flywheel, there is a shaft on the driving sprocket, and there are two pedals at both ends of the shaft. The shaft is installed in a fixed bushing on the frame and can rotate. The pawl sprocket is supported by the frame. The center of the rear wheel is connected to the drive sprocket through an endless chain. A ratchet mechanism, that is, a one-way clutch, is installed on the pawl sprocket to transmit the positive rotation force of the drive sprocket to the rear wheel shaft, that is, The user can sit on the seat and hold the handlebar with both hands, and then step on the pedal to rotate the drive sprocket in the forward direction, and the positive rotation force on the drive sprocket can be transmitted to the pawl sprocket through the chain, and thus is transmitted to the rear wheel, thereby turning the rear wheel and moving the bike forward on the ground, however, the detent sprocket's one-way clutch does not transfer the reverse rotational force on the drive sprocket when the drive sprocket rotates in reverse To the rear wheel, the pawl sprocket can only idle, that is, its output wheel can only be driven forward in one direction
