Abstract
The utility model relates to a front-wheel steering controller of bicycle and tricycle. A cone friction transmission device is mainly composed of a handle assembly, a front frame spindle, a spring, an upper sleeve on front frame, a back frame connection rod, a rubber pad and a screw cap. The upper end of the front frame spindle is provided with an outer conical surface. The handle assembly is provided with an inner conical surface. The handle assembly is matched with the front frame spindle through a conical surface. The spring is sleeved outside the front frame spindle. The sleeve on the front frame is sleeved outside the spring. The back frame connection rod is sleeved outside the sleeve on the front frame. The rubber pad is provided at the top end of the back frame connection rod. The cone friction transmission device uses cone friction for transmitting torque and realizing turning of the front wheel by the handle. A damping spring is equipped for adapting the transmission of damping type bicycle or tricycle head.
Description
Technical field
The utility model relates to the front-wheel steering control setup of bicycle, three-wheel vehicle, especially a kind ofly utilizes the conical surface friction transfer torque, and has the conical surface friction driving device of spring shock absorption function.
Background technology
The basic structure of existing bicycle handle bar transmission is that handlebar and front vehicle frame joining place are in the inclined-plane interlock, by the mode of tightening nuts, makes two inclined-plane leak-tight joints, thereby realizes the purpose of transfer torque control front-wheel direction.This structure is less with back vehicle frame shell clearance because of front vehicle frame, and the damping spring difficulty is installed in sleeve pipe, otherwise again can't transfer torque.
Summary of the invention
In order to address the above problem, on existing correlation technique basis, the utility model provides a kind of conical surface friction driving device, by changing the moment of torsion transfer mode of handlebar and front vehicle frame, realize control front-wheel steering flexibly, solved the space requirement that damping spring is installed simultaneously in sleeve pipe.
The technical scheme that the utility model adopted is:
The conical surface friction driving device mainly is made of cover, back vehicle frame pipe link, rubber pad, nut on handlebar assembly, front vehicle frame mandrel, spring, the front vehicle frame, described front vehicle frame mandrel upper end has male cone (strobilus masculinus), described handlebar assembly has inner conical surface, cone match between described handlebar assembly and the described front vehicle frame mandrel is with static friction power transfer torque between the conical surface.Described spring housing is enclosed within the outside of described spring in the outside of described front vehicle frame mandrel on the described front vehicle frame, described back vehicle frame pipe link is enclosed within the outside of overlapping on the described front vehicle frame, and described rubber pad is positioned at vehicle frame pipe link top, described back.When described handlebar assembly downward, closely cooperate between the described front vehicle frame mandrel and described handlebar assembly two conical surfaces, described rubber pad is compressed and promotes described back vehicle frame connecting rod and moves down, the while compression spring, thereby described front vehicle frame mandrel, described back vehicle frame connecting rod, described handlebar assembly are flexibly coupled together, make front-wheel have cushioning effect.When described handlebar assembly rotated, the static friction power that forms between the described front vehicle frame mandrel and described handlebar assembly two conical surfaces forced described front vehicle frame mandrel to rotate thereupon, realized turning to of handlebar control front-wheel.
The beneficial effects of the utility model are:
The conical surface friction driving device utilizes the conical surface friction transfer torque, and simple structure is reasonable, working stability and easy for installation; Damping spring is installed, is applicable to the transmission of shock-absorbing type headstock.
Description of drawings
Further specify below in conjunction with figure of the present utility model:
Fig. 1 is the longitudinal profile constructional drawing of described conical surface friction driving device.
Among the figure, 1. handlebar assembly, 2. front vehicle frame mandrel, 3. spring 4. overlaps on the front vehicle frame, 5. back vehicle frame pipe link, 6. rubber pad, 7. nut, the inner conical surface cooperation place of the male cone (strobilus masculinus) of 8. described front vehicle frame mandrel and described handlebar assembly.
The specific embodiment
As Fig. 1, described conical surface friction driving device mainly is made of cover, back vehicle frame pipe link, rubber pad, nut on handlebar assembly, front vehicle frame mandrel, spring, the front vehicle frame, described front vehicle frame mandrel (2) upper end has male cone (strobilus masculinus), described handlebar assembly (1) has inner conical surface, cone match (8) between described handlebar assembly and the described front vehicle frame mandrel.Described spring (3) is enclosed within the outside of described front vehicle frame mandrel (2), cover (4) is enclosed within the outside of described spring (3) on the described front vehicle frame, described back vehicle frame pipe link (5) is enclosed within the outside of cover (4) on the described front vehicle frame, and described rubber pad (6) is positioned at vehicle frame pipe link (5) top, described back.
During installation, go up installation described spring (3) at described front vehicle frame mandrel (2), be inserted in described back vehicle frame pipe link (5), the described rubber pad (6) of packing into successively again, described handlebar assembly (1) are tightened described nut (7) at last.
Claims (1)
1. conical surface friction driving device, mainly by handlebar assembly, the front vehicle frame mandrel, spring, overlap on the front vehicle frame, back vehicle frame pipe link, rubber pad, nut constitutes, it is characterized in that: described front vehicle frame mandrel upper end has male cone (strobilus masculinus), described handlebar assembly has inner conical surface, cone match between described handlebar assembly and the described front vehicle frame mandrel, described spring housing is in the outside of described front vehicle frame mandrel, be enclosed within the outside of described spring on the described front vehicle frame, described back vehicle frame pipe link is enclosed within the outside of overlapping on the described front vehicle frame, and described rubber pad is positioned at vehicle frame pipe link top, described back.
