Abstract
The existing three-speed rear derailleur is replaced by a five-speed rear derailleur, which causes unnecessary waste. The utility model provides a chain ware is dialled to three-speed back adopts flat swing mechanism, the steel cable, the steel rope cover gets into the direct rear derailleur that pulls in the front portion, need not wind the rear portion to the chain ware is dialled to the back. Simple structure practices thrift the cost, has alleviateed the adjustment control ware operating force of shifting, reaches better higher derailleur performance.
Description
The utility model belongs to the variable speed bicycle rear derailleur.
Existing bicycle three fast rear derailleurs all are to be replaced by five fast rear derailleurs, cause unnecessary waste.
The purpose of this utility model is at above-mentioned deficiency, and a kind of three fast rear derailleurs are provided.Its structure adopts the swinging gear of flat formula, and steel cable, steel rope sleeve enter direct traction rear derailleur from the front portion, does not need around to the rear derailleur rear portion, and is simple in structure, saves cost, alleviates speed setting controller shift control power simultaneously, reaches better higher group chain performance.
Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 2 is the utility model side-looking structural representation.
Accompanying drawing 3 is the utility model fixed bearing 1 structural representation.
Accompanying drawing 4 is the utility model fixed bearing 1 plan structure scheme drawing.
Accompanying drawing 5 is the utility model tumbler bearing 2 structural representations.
Accompanying drawing 6 is the utility model tumbler bearing 2 plan structure scheme drawings.
The mark sequence number is expressed as follows among the figure:
1-fixed bearing, 2-tumbler bearing, 3-lead chain mechanism, 4-fulcrum, 5-back seat axle, 6-set screw, 7,8-torsion spring, 9-stop screw, 10-tight rope screw, 11-tightening screw, 12-link slot, 14,15,17-axis hole, 13,16,18-tapped bore
Below in conjunction with accompanying drawing technical solutions of the utility model are described:
Among Fig. 1,2, after fixed bearing 1 (along bicycle directional) deflection below extension forward, the right angle extends to the inside again, and this right angle extended surface of fixed bearing (1) is connected with the cardinal extremity of tumbler bearing (2) by fulcrum (4), constitutes the oscillating type connecting rod mechanism with this.Torsion spring (7) is housed, so that tumbler bearing (2) keeps restoring force towards diagram F direction on the fulcrum (4).Tumbler bearing (2) is the center swing with fulcrum (4), amplitude of fluctuation is by two stop screw (9) controls that are arranged on fixed bearing (1) lower end, the tail end of tumbler bearing (2) by back seat axle (5) with lead chain mechanism (3) and be connected, torsion spring (8) is housed on the back seat axle (5), keep rotational force toward the clockwise direction so that lead chain mechanism (3), lead the rear that chain mechanism (3) is positioned at fixed bearing (1).
Among Fig. 3,4, fixed bearing (1) is by sheet material machine-shaping, fixed bearing (1) top processes a link slot (12), at two screws (13) of placing stop screw (9) of fixed bearing (1) lower end processing, processing is used for installing the axis hole (14) of fulcrum (4) on inner side plane, and processing is used for regulating the tapped bore (16) of the set screw (6) of steel cable degree of tightness on the plane that outside right angle, the place ahead, lower end of fixed bearing (1) extends.
Among Fig. 5,6, tumbler bearing (2) adopts sheet material machine-shaping, front end in tumbler bearing (2), be processed with and can pass through fulcrum (4) and fixed bearing (1) bonded assembly axis hole (15), the plane that downward right angle, tumbler bearing (2) rear end extends is provided with and is used for connecting the axis hole (17) of the back seat axle (5) of leading chain mechanism (3) and the tapped bore (18) of placing tight rope screw (10).
The utility model is when installing and using, with tightening screw (11), nut (not marking among the figure) fixed bearing (1) is fixed in the vehicle frame butt strip, lead chain mechanism (3) and be in three speed and fly the corresponding position of medium chain sheet, centre of sprocket line and three speed of leading chain mechanism (3) fly medium chain sheet line of centers in-line and are parallel to the vehicle frame butt strip.Handle governor handle, wire rope traction tumbler bearing (2) is that swing at the center with fulcrum (4), thereby reaches the purpose of speed change.
The protrusion amount is few outwardly for the more common rear derailleur of the utility model, has avoided the possibility of overturning and contacting to earth.Be positioned at the place ahead of tumbler bearing (2) again because of fixed bearing (1), set screw (6) is fixed on the preceding downside of fixed bearing (1), steel cable, steel rope sleeve directly are connected with governor handle, do not need around rear portion to rear derailleur, thereby alleviated the bending resistance and the stretch ratio of steel cable, steel rope sleeve, can alleviate governor handle shift control power simultaneously.
Claims (3)
1, three fast rear derailleurs, comprise fixed bearing (1), tumbler bearing (2), lead chain mechanism (3), it is characterized in that: after the fixed bearing 1 deflection below extension forward, the right angle extends to the inside again, this right angle extended surface of fixed bearing 1 is connected with the cardinal extremity of tumbler bearing (2) by fulcrum (4), torsion spring (7) is housed on the fulcrum (4), tumbler bearing (2) is the center swing with fulcrum (4), amplitude of fluctuation is by two stop screw (9) controls that are arranged on fixed bearing (1) lower end, the tail end of tumbler bearing (2) by back seat axle (5) with lead chain mechanism (3) and be connected, torsion spring (8) is housed on the back seat axle (5), leads the rear that chain mechanism (3) is positioned at fixed bearing (1).
2, according to claim 1 three fast rear derailleurs, it is characterized in that: fixed bearing (1) is by sheet material machine-shaping, fixed bearing (1) top processes a link slot (12), at two screws (13) of placing stop screw (9) of fixed bearing (1) lower end processing, processing is used for installing the axis hole (14) of fulcrum (4) on inner side plane, and processing is used for regulating the tapped bore (16) of the set screw (6) of steel cable degree of tightness on the plane that outside right angle, the place ahead, lower end of fixed bearing (1) extends.
3, according to claim 1 three fast rear derailleurs, it is characterized in that: tumbler bearing (2) adopts sheet material machine-shaping, front end in tumbler bearing (2), be processed with and can pass through fulcrum (4) and fixed bearing (1) bonded assembly axis hole (15), the plane that downward right angle, tumbler bearing (2) rear end extends is provided with and is used for connecting the axis hole (17) of the back seat axle (5) of leading chain mechanism (3) and the tapped bore (18) of placing tight rope screw (10).
