Abstract

The present invention relates to a braking lever assembly, more particularly, to a braking mechanism assembly for a motorcycle or bicycle in which the braking mechanisms of both the front and rear wheels can be simultaneously and synchronously actuated to ensure a safe and effective braking. As a result, driving safety can be properly ensured. The braking lever assembly generally comprises a mounting socket and a braking lever which is pivotally attached to the mounting socket. The mounting socket is provided with a pair of guiding holes for the braking cables. The braking lever is pivotally connected with a pulling rod by a 8-shape plate and the pulling rod in turn is provided with a pair of positioning holes for pivotally attaching the anchoring head of the braking cables therein. Wherein when the braking lever is depressed, the 8-shape plate together with the pulling rod are pulled backward such that the braking cables are pulled backward to actuate the braking mechanism for both the front and rear wheels. The wearing of the lining of each braking mechanism can be automatically adjusted and compensated by the shifting of the pulling rod which is pivotally attached to the 8-shape plate. Consequently, the front and rear braking mechanisms can be simultaneously actuated with equal braking force to ensure riding safety.

A braking lever assembly for synchronically actuating braking mechanisms, comprising

a mounting socket which can be fixedly mounted onto the handlebar of a bicycle or motorcycle, a front portion of said mounting socket being provided with a front and rear cable guiding holes for braking cables, each of said cable guiding holes being provided with a sliding groove which is in communication with the corresponding guiding hole, said rear cable guiding hole being provided with an elongate hole, said mounting socket being provided with a hidden groove at rear portion;
and
a braking lever being pivotally attached to said mounting socket, a pulling end of said braking lever being provided with a connecting groove having a through hole thereof, a 8-shape plate having a front and rear connecting holes being pivotally connected within said connecting groove by means of a pin shaft which passes through said through hole of said connecting groove and said rear hole of said 8-shape plate, said braking lever being further provided with a pulling rod which has a left and right positioning holes at both ends for attaching an anchoring head of said brake cables therein respectively, said pulling rod being further provided with a passage which has a through hole thereof and the front hole of said 8-shape plate can be inserted into said passage and pivotally retained therein, each of said positioning holes of said pulling rod being provided with a guiding gap for said one of respective braking cables.
