Description

Embedded bushing for transmission shaft coupling with high durability
Technical Field
The present invention relates to a built-in bush for a propeller shaft coupling for connecting a transmission output shaft of a power unit including an engine and a transmission of a vehicle and a propeller shaft or for connecting a propeller shaft and a shaft of a rear wheel axle to each other, wherein a support member is formed on a main body portion of the built-in bush to improve durability.
Background
First, a conventional technique will be described, and a rear-wheel drive vehicle including a four-wheel drive vehicle is generally capable of driving rear wheels by transmitting rotational power generated from a transmission output shaft of a front power unit to a rear wheel axle (rear axle) through a propeller shaft (propeller shaft).
At this time, the propeller shaft is coupled to the transmission output shaft of the power unit and the rear wheel shaft at a predetermined angle (α, β), and thus, moves in the process of transmitting the rotational power to the transmission output shaft → the propeller shaft → the rear wheel shaft, and thus, in order to minimize the movement in the coupling, the propeller shaft is coupled to the transmission output shaft and the propeller shaft is coupled to the rear wheel shaft by means of a rubber (rubber) type propeller shaft coupling (coupler).
The coupler for a transmission shaft is configured such that a central electric wire (cord) and upper and lower electric wires are alternately wound around a plurality of inner sleeves (inner bush) made of a steel material in a cylindrical shape and then are fixed by being covered with rubber.
There are three main types of existing shaft couplings for transmission shafts: a first type in which three center side wires C1 and three pairs of upper and lower side wires C2 and C3 are alternately wound in a tightly wound manner around six cylindrical inner sleeves B1, and collar bushes B2 and B3(collar bush) are coupled symmetrically to each other at the upper and lower ends of the inner sleeves B1, respectively, and then wrapped and fixed with rubber (R); a second type in which flange portions F1, F2, which separate and separate center side wires and upper and lower side wires alternately wound around six cylindrical inner sleeves (B1), and upper and lower side collar bushings B2, B3 of type 1 are integrally formed; a third type in which a fitting bush B4 for crimping the center side electric wire and upper and lower collar bushes B2 and B3 are separately formed, and upper and lower electric wires C2 and C3 are crimped between the fitting bush B4 and the upper and lower collar bushes B2 and B3, respectively.
The first type of shaft coupling for a propeller shaft has advantages in that a series of assembling and manufacturing processes of curling a center side electric wire (C1) and upper and lower side electric wires C2 and C3 in an inner housing B1 and integrally wrapping them with rubber (R) after collar bushes are coupled to upper and lower ends of the inner housing (B1) are quick and simple, but the electric wires C1, C2 and C3 contact each other and friction occurs between the center side electric wire C1 and the upper and lower side electric wires C2 and C3, so that durability is reduced and life is short.
The second type of propeller shaft coupling has high durability by reducing friction between the electric wires C1, C2, and C3, but has a difficulty in assembling the electric wires C1, C2, and C3 into the respective grooves formed between the flange portions F1 and F2 and the upper and lower collar bushes B2 and B3, and is manually operated, thereby greatly reducing productivity.
The third type of drive shaft coupling is easy to assemble and excellent in productivity, and can reduce friction among the electric wires C1, C2, and C3 to improve durability slightly, but the embedded bushing B4 coupled to the outer side of the cylindrical inner sleeve B1 moves on the inner sleeve B1 itself, and thus lacks durability.
Further, the movement occurring during the transmission of the rotational power to the transmission output shaft → the propeller shaft → the rear wheel axle becomes a factor of noise and vibration occurring when the vehicle is running, and the structure of all of the first, second and third types of propeller shaft couplers cannot prevent the movement.
However, since the insert bush of the coupling formed on the transmission shaft is made of plastic or synthetic resin, there is a disadvantage in that durability is reduced.
In addition, the durability of the embedded bushing is reduced, so that the winding space is narrow.
Therefore, conventionally, a 'coupler for propeller shaft of rear wheel drive vehicle' disclosed in publication No. 10-2010-0056006 and a 'coupler structure for propeller shaft' disclosed in publication No. 10-2013-0017162 have been disclosed, but the above-described problems have not been improved yet.
