Description

The short version

The present novelty is the improvement of the pedal construction, which includes an axle, a bearing and a pedal. The axle has a stop and an end for the bearing. At the end of the stop, which faces the end for the bearing, a boundary wall and a buffer slot are provided. The buffer slot encloses the boundary wall circumferentially. The bearing is mounted on the end for the bearing. The inner ring of the bearing is axially against the boundary wall, wherein the outer ring of the bearing is the buffer slot axially corresponding. Through the whole pedal, there is a rotary hole in the axial direction, in which the axis of the pedal passes through and in which a bearing is provided. When the pedal is pushed sideways, the outer ring goes into the buffer slot and abuts against the inner wall of the buffer slot, whereby the lateral impact force is absorbed and mitigated by the stop, so that the deformation and damage of the bearing can be avoided.

The technical area

This novelty is the construction technique of the bicycle pedal. In particular, it is the improved pedal construction in which the lateral impact force can be absorbed to avoid deformation and damage to the inner bearing of the pedal.

The state of the art

Pedal is an important component of the power transmission mechanism of the bicycle, on which it depends whether the pedaling force of the driver is easily transmitted and whether the driver can ride the bike well and comfortably.

As the pedal is pedaled, depending on the treadle, the pedal turns relative to the axle so that cycling can be continued with little problem and unhindered. Bearing is an important component that can facilitate turning the pedal about the axis. If the bike is turned off, it can be blown by the crosswind to tilt, with the side of the wheel bumps on the ground. It may also be, especially in the beginner, the bike overturning while driving. The pedals are on both sides of the bike and are always the first to hit the ground when the bike tilts. If the bike overturns, the pedal must not only absorb the weight of the bike but also the balance force when overturning, which can damage the bearing.

From the Taiwanese Patent No. M420483 It can be seen that the inner structure of the pedal axle includes a pedal, at least one bearing, an axle and a washer. In the axial direction, a turning hole goes through the entire pedal. On the inner wall of the rotary hole there is a long rib. The bearing is mounted in the turning hole. The axle goes into the turning hole and connects to the bearing. On the axis a step is provided. The bearing can be fixed between the step and the grooved rib. At one end of the axle there is an internal thread which enters the axle in the axial direction. A screw can screw into the internal thread. One end of the screw goes through a washer and screwed into the internal thread. The bearing can be fixed between the washer and the grooved rib.

In the conventional technique, there are two places where the bearing can be fixed. One place is between the step and the ridged rib and the second place is between the washer and the ridged rib.

The construction of the pedal in the conventional technique is already improved, but it still has shortcomings. The inner ring on one side of the bearing stands against the step and the outer ring on the other side of the bearing stands against the raised rib. Although the two sides of the bearing are clamped, but the outer ring of the bearing on the side of the step and the inner ring of the bearing on the side of the protruding ribs face no counterpart. The outer ring of the bearing, which is clamped between washer and the grooved rib, on the side of the lower disc and the inner ring on the side of the grooved rib are also no counterpart.

If the pedal is pushed from the sides, the bearing is pressed by the external force. The outer ring of the bearing, the z. B. between the step and the grooved rib is first pressed by the grooved rib in the axial direction inwards. However, since the inner ring is against the step, the outer ring and the inner ring of the bearing are unevenly caused by the impact force, whereby the construction of the bearing can be deformed and damaged.

The same thing happens with the bearing mounted between the washer and the ridged rib. The bearing is deformed and damaged by the same effect.

The above-mentioned defects of the pedal bearing must be improved and eliminated so that the bearing is not deformed or damaged by the external force.

The object of the invention

This novelty is the improved pedal construction. The object of the present novelty is to avoid or eliminate the deformation and damage to the bearing of the pedal, which are caused by the uneven effect of the impact force.

The further object of the present innovation is to achieve unimpeded and easy turning of the pedal relative to the axis.

In order to solve the problems and achieve the effects, the present novelty is essentially composed of an axle, a bearing and a pedal.

The axle has a stop and an end for the bearing. At the end of the stop, which faces the end for the bearing, a boundary wall and a buffer slot are provided. The buffer slot encloses the boundary wall circumferentially.

The bearing is mounted on the end for the bearing. The inner ring of the bearing is axially against the boundary wall, wherein the outer ring of the bearing is the buffer slot axially corresponding.

Through the whole pedal, there is a turning hole in the axial direction, in which the axis of the pedal passes through and in which a bearing is provided.

When the pedal is pushed sideways, the outer ring goes into the buffer slot and abuts against the inner wall of the buffer slot, whereby the lateral impact force is absorbed and mitigated by the stop, so that the deformation and damage of the bearing can be avoided.
