Abstract

The utility model discloses a swing transmission type bicycle. A driving wheel is designed into two diameter-changing wheels; a sprocket wheel with a one-way clutch and a chain are both designed into two and are corresponding to the two diameter-changing wheels; one end of the chain is hinged on the diameter-changing wheel, and the other end is hinged with a rear fork of a bicycle frame through a tensioner. The axis of the tensioner is hinged with a chain, and the other end of the chain is hinged on the diameter-changing wheel corresponding to the chain. A back rest of the bicycle frame is provided with an associated movement device of two driving force arms. The utility model has the advantages of novel structure, convenient use and labor saving; because the two driving force arms do swing movement, the length of the arms can be regulated.

Description

Oscillating type driving type bicycle

The utility model belongs to a kind of bicycle and man, is a kind of oscillating type driving type bicycle specifically.

Existing bicycle all is to continue to use traditional one-sided chain-driving, and two drive the arm of force makes circular movement.This traditional bicycle, its shortcoming are that the foot-operated arm of force that drives is made circular movement, make that the driving arm of force is too small, thereby have limited the increase of driving torque.Like this, just be difficult to, reach purpose laborsaving and the raising speed of a motor vehicle by improving torque; Otherwise, will require great effort very much.

The purpose of this utility model is to provide a kind of driving arm of force to do the oscillating type motion, can increase the driving arm of force, thereby reach laborsaving, improves a kind of oscillating type driving type bicycle of the speed of a motor vehicle.

The utility model is achieved in that drive wheel design is become reducing, be contained in the diameter-changing wheel (2 on the axis of vehicle frame both sides, 8), drive the arm of force (1,7) with two diameter-changing wheels (2,8) be connected mutually, on rear vehicle shaft, be equipped with and two diameter-changing wheels (2,8) sprocket wheel (4) of corresponding two band free-wheel clutchs, one end of two chains (3) is respectively with two diameter-changing wheels (2,8) be hinged, the other end is hinged with the vehicle frame back vent by the sprocket wheel and two tension wheels (5) of band free-wheel clutch, one end of two chains (6) is hinged on corresponding with it diameter-changing wheel (2 respectively, 8) on, the other end is hinged on the axle of corresponding with it two tension wheels (5).On the vehicle frame back rest (12) both sides, be provided with and make two to drive the be associated device of motion of the arm of forces (1,7), that is to say that the coupled movements device that then is located at the frame back rest (12) drives the driving arm of force (7) upward movement when driving the arm of force (1) downwards during actuation movement.This coupled movements device can be designed to be hinged on the fork (15) on the vehicle frame back rest (12), and drives the connecting rod mechanism that connecting rod (14,20) that the arm of forces (1,7) and fork (15) two ends are hinged constitutes mutually with two; Also associated apparatus can be designed to be fixed on the support arm (11) on the vehicle frame back rest (12), constitute mutually with the steel cable (13) that is hinged on the pulley (9) on the support arm (11) by connecting rod (10) and be hinged by pulley (9) the two driving arm of forces (1,7) together.Drive the arm of force (1,7) with two and be designed to socket type.Like this can regulated at will two length that drive the arm of forces (1,7).

The utility model novel structure, easy to use.Do hunting motion owing to drive the arm of force, so can regulate the length that drives the arm of force according to the people of all ages and classes.Because it is adjustable to drive the arm of force, and likens the propulsive effort brachium of circular movement to,, can improve the speed of a motor vehicle so the utility model has the advantages that laborsavingly.

Accompanying drawing 1 is a structural representation of the present utility model.

Accompanying drawing 2 is of the present utility model two to drive the structural representation of a kind of embodiment of the coupled movements device of the arm of forces.

Accompanying drawing 3 is of the present utility model two to drive the structural representation of another kind of embodiment of the coupled movements device of the arm of forces.

Reality is closed accompanying drawing embodiment of the present utility model is described further:

Drive wheel design is become two diameter-changing wheels (2,8), driving the arm of force (1,7) is separately fixed on two diameter-changing wheels (2,8), two diameter-changing wheels (2,8) are contained on the axis of vehicle frame, sprocket wheel (4) with the corresponding band free-wheel clutch of two diameter-changing wheels is housed on the axle of back wheels of vehicle, one end of two chains (3) is hinged on two diameter-changing wheels (2,8) respectively and fixes the place with the two driving arm of forces (1,7), and the other end is hinged on the back vent of vehicle frame by two tension wheels (5); One end of two chains (6) is hinged on corresponding with it wheel the (2,8) same two respectively and drives the another side that the arm of forces (1,7) fix the place, and the other end axle of same corresponding two tension wheels (5) with it respectively is hinged.Shown in the optimum implementation (as Fig. 3) of the running gear that the two driving arm of forces (1,7) are associated.It is by the fork that is hinged on the vehicle frame back rest (12) (15), and and fork (15) two ends and two drive the connecting rod mechanism that connecting rod (14,20) that the arm of forces (1,7) are hinged is formed.Another embodiment (as Fig. 2) is the pulley (9) that is hinged by connecting rod (10) by support arm that is fixed on the vehicle frame back rest (12) (11) and same support arm (11), and the steel cable (13) that is hinged by the pulley (9) and the two driving arm of forces (1,7) constitutes mutually.In order to adapt to all ages and classes human needs, drive the arm of forces (1,7) with two and be designed to socket type, like this can regulated at will two drive the length of the arm of forces (1,7).
