Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of motorcycle disc brake handle opening angle adjusting technology, in particular to a kind of motorcycle disc brake handle opening angle adjusting mechanism. BACKGROUND

[0002] Motorcycle disc brake handle is usually arranged at the front end of handlebar, and when braking, it is made by holding handlebar and handle simultaneously and pinching, so that handle is close to handlebar side, thereby pulling disc brake's flexible shaft, so that the valve of brake hydraulic system is opened, brake clamp clamps brake disc, thereby achieving the purpose of motorcycle braking. When handle is usually pulled, handle rotates along hinge shaft, and flexible shaft fixedly arranged at the other end of handle rotates with handle, thereby achieving the purpose of pulling disc brake flexible shaft. Therefore, when handle is not pulled, it is set angle (i.e. opening angle) with handlebar, and when handle is pinched, it can pull disc brake flexible shaft set distance. However, the size of palm of motorcycle driver is not the same, in order to meet the driver with different palm size can effectively control brake, handle opening angle adjusting mechanism is usually arranged at motorcycle disc brake handle. Prior art disc brake handle opening angle adjusting mechanism includes hinge seat, handle, adjusting screw and adjusting nut;The hinge seat is fixed at the front side of motorcycle handlebar;The handle is hinged on hinge seat, and deep blind hole is arranged in the longitudinal direction of the front end of handle, and rectangular notch is arranged in the transverse direction of the front end of handle, and rectangular notch is just in the middle section of blind hole;The outer circle of adjusting nut is provided with teeth and is installed in rectangular notch, adjusting screw is inserted in blind hole and is engaged with adjusting nut, and the outer side end of adjusting screw is connected with disc brake flexible shaft (see the accompanying drawings Figure 1 、 2 , in the figure, a is handlebar, b is handle, c is hinge seat, d is adjusting screw, e is adjusting nut). Obviously, pinching handle can make handle rotate along hinge shaft, thereby pulling disc brake flexible shaft. In addition, rotating adjusting nut can adjust the axial position of adjusting screw in blind hole, thereby adjusting the opening angle of disc brake handle. In order to ensure the effectiveness of brake, it is usually necessary to have preset tension on disc brake flexible shaft when handle is not pinched, so that handle is pinched, and flexible shaft is immediately pulled. It can be seen that the adjusting function of prior art disc brake handle opening angle adjusting mechanism is actually double, one is to adjust the opening angle of handle, and the other is to adjust the preset tension of flexible shaft. This brings difficulty to the adjustment of handle opening angle, that is, the opening angle of handle cannot be adjusted too small, otherwise, the preset tension will be lost. On the other hand, the preset tension of disc brake flexible shaft may change with the increase of brake times, thereby causing the change of handle opening angle.

[0003] Obviously, prior art disc brake handle opening angle adjusting mechanism has the problems of difficulty in adjusting handle opening angle and possible change of handle opening angle. SUMMARY

[0004] In order to solve the problems of the handle opening angle adjusting difficulty and the possible change of the handle opening angle of the prior art disc brake handle opening angle adjusting mechanism, the utility model provides a disc brake handle opening angle adjusting mechanism of a motorcycle.
