Abstract
The utility model discloses a kind of rear brake rocking arm of motor bike, an end of rocker body is provided with and is used for and the circumferential hole of captiveing joint of brake camshaft, and the other end is opened trouble and is used to install drag-line, and these both sides of opening the trouble end are provided with the hole that is used to install bearing pin symmetrically.One of captive joint forms single-piece with rocker body and makes out the trouble end form two arm plates that are used to install the opening of drag-line on the rocker body, and the arm plate is provided with and opens the cooresponding hole, hole that is used to install bearing pin on the trouble end.The utility model is simple in structure, can realize the forward and backward drg synchronous braking of motor bike, the sideslip that wags the tail when avoiding the motor bike emergency brake, even the phenomenon of tumbling takes place.
Description
Technical field
The utility model relates to a kind of drg rocking arm of motor bike, particularly a kind of rear brake rocking arm that is applicable to two-wheeled, three-wheel and four-wheel motor cycle.
Background technology
At present, the brake system of motor bike all is to realize the braking of front and rear wheel by the forward and backward drg handled respectively, the rocking arm of forward and backward drg is connected with forward and backward brake operation mechanism by drag-line respectively separately, and the trouble end of opening of rocking arm is an opening that is used to install drag-line.During motorcycle driving, braking under normal circumstances just can be controlled speed of a motor vehicle brake by handling rear brake; But the braking when emergency situation often needs to handle simultaneously forward and backward drg and controls the speed of a motor vehicle, realizes emergency brake.Because forward and backward drg is handled respectively, in case handle asynchronous, will cause the effect of emergency brake not ideal enough, especially when operation, front brake is braked prior to rear brake, front-wheel stop and trailing wheel still rotates under dynamic action can have a strong impact on braking effect, causes the motor bike sideslip that wags the tail, even tumble, cause personnel casualty accidents.
Summary of the invention
The purpose of this utility model provides a kind of rear brake rocking arm of motor bike, and this rear brake rocking arm can be connected with the manipulating pulling cable of forward and backward braking respectively, and braking can not stationary problem when solving emergency brake.
The purpose of this utility model is achieved in that an end of rocker body is provided with and is used for and the circumferential hole of captiveing joint of brake camshaft, the other end is opened trouble and is used to install drag-line, these both sides of opening the trouble end are provided with the hole that is used to install bearing pin symmetrically, it is characterized in that: one of captive joint forms single-piece with rocker body and makes out the trouble end form two arm plates that are used to install the opening of drag-line on the rocker body, and the arm plate is provided with and opens the cooresponding hole, hole that is used to install bearing pin on the trouble end.
Owing to adopted such scheme; one of captive joint forms single-piece with rocker body and makes out the trouble end form two arm plates that are used to install the opening of drag-line on the rocker body; the arm plate is provided with and opens the cooresponding hole, hole that is used to install bearing pin on the trouble end; a bearing pin is assemblied in rocker body opens in the hole on trouble end symmetrically arranged hole, both sides and the arm plate; make two openings opening the trouble end that are used to drag-line is installed of this rocking arm that two manipulating pulling cables can be installed respectively; drag-line with after brake operation mechanism be connected, another root drag-line is connected in the preceding brake operation mechanism with preceding brake operation drag-line.Can make motorcycle brake system under the situation of brake operation mechanism behind the individual operation, rear brake is braked alone; Before individual operation under the situation of brake operation mechanism, the safety that improves motorcycle driving the phenomenon that forward and backward drg can not synchronous braking appears, in forward and backward drg synchronous braking when having eliminated emergency brake.Simultaneously since on the rocker body captive joint arm plate, the intensity of rocking arm is enhanced, both be applicable to the drg of two-wheeled motor vehicle, also be applicable to three, the drg of four-wheel motor cycle.
The utility model is simple in structure, can realize the forward and backward drg synchronous braking of motor bike, the sideslip that wags the tail when avoiding the motor bike emergency brake, even the phenomenon of tumbling takes place.
The utility model is described in further detail below in conjunction with drawings and Examples.
Description of drawings
Fig. 1 is a kind of example structure sketch of the present utility model;
Fig. 2 is an another kind of example structure sketch of the present utility model;
Fig. 3 is a lateral plan of the present utility model;
Fig. 4 is assemblied in scheme drawing on the drg for the utility model.
The specific embodiment
Referring to Fig. 1, Fig. 3, rocker body 1 will be struck out after the steel plate cutting.One end of rocker body 1 is provided with and is used for and the circumferential hole of captiveing joint 4 of brake camshaft, and this hole 4 is the splined hole of opening; The other end bends away trouble formation opening and is used to install drag-line, and these both sides of opening the trouble end are provided with the hole 5 that is used to install bearing pin symmetrically.One of captive joint forms single-piece with rocker body and makes out the trouble end form two arm plates 2 that are used to install the opening of drag-line on the described rocker body 1, arm plate 2 be provided with and open the 5 cooresponding holes 5, hole that are used to install bearing pin on the trouble end ', hole 5 on the arm plate 2 ' with the hole 5 same axial lines on the both sides of opening trouble end, in order to bearing pin that connects manipulating pulling cable of common installation.Two parts centre that described arm plate 2 is clipped in the rocker body 1 of drawing is divided into two openings that are used to install drag-line opening the trouble end, by welding the fixing integral body that forms, perhaps adopt bolt or rivet to be fastenedly connected also to fix to form wholely, strengthen the intensity of rocking arm and in order to two drag-lines to be installed.Described arm plate 2 also can be carried on the back in rocker body 1 outside sweep and form opening, fixingly forms wholely by welding, and perhaps adopts bolt or rivet to be fastenedly connected also to fix to form wholely, can strengthen the intensity of rocking arm equally and in order to two drag-lines to be installed.Do not interfere with brake casing when avoiding rocking arm to rotate, according to the drg of different size, the arm section of rocker body 1 can be made as cranks arm, and also can be made as straight-arm (as shown in Figure 2).
Referring to Fig. 4, this rocker body 1 is connected with brake camshaft 11 splines of the rear brake 10 of motor bike by splined hole 4, the opening of splined hole 4 makes rocker body 1 fixing with brake camshaft 11 with bolt 9 lockings; What bearing pin 3 was installed in rocker body 1 opens the trouble end, and two drag-lines 6,7 are fixedly connected on out on the bearing pin that trouble holds with bolt 8 from two openings respectively.A drag-line 6 is connected with back brake operation mechanism, and another root drag-line 7 is connected in the preceding brake operation mechanism with preceding brake operation drag-line.During motorcycle driving, slowing-down brake generally speaking, brake operation mechanism makes the rear brake braking behind the individual operation; Brake in emergency circumstances, handle forward and backward brake operation mechanism simultaneously, or brake operation mechanism before the individual operation, all can make forward and backward drg synchronous braking, the phenomenon that forward and backward drg can not synchronous braking appears in the time of can eliminating emergency brake, the sideslip that wags the tail when avoiding the motor bike emergency brake, even the phenomenon of tumbling takes place.
This rocking arm is applicable to the drg of two-wheeled, three-wheel, four-wheel motor cycle.
