38,38 extension springs that are provided in a side of between retention tab 17,17 and equalizer section the 31, the 1st pipe link 29, described each extension spring 38 are used to prevent that left handle 1, right handles 3 from producing and rocking.

In addition, the 39th, fluid storage tank, it is connected with the flexible pipe installation portion 19 of master cylinder cover 11 by the relaying flexible pipe, and the braking liquid of the specified amount of packing in this fluid storage tank 39, this fluid storage tank 39 are installed in by naked eyes can be confirmed to brake on the position of liquid measure from the outside.

The brake for two-wheeled car of present embodiment has aforesaid structure, below, the sequence of erection of each steel wire 34,36,37 and the control method of each several part are illustrated.

At first, the steel wire main body 37A that drg is driven steel wire 37 is connected on the steel wire connecting bore 31B of equalizer section 31, and sleeve pipe 37B is installed on the intermediate bracket 14.Then, the steel wire main body 34A of left drg steel wire 34 is connected on the steel wire connecting bore 31A of equalizer section 31, before with nut 35 sleeve pipe 34B being installed on the lateral bracket 13.In addition, the steel wire main body 36A of right drg steel wire 36 is connected on the steel wire connecting bore 29B of the 1st pipe link 29, sleeve pipe 36B is installed on the lateral bracket 15 of back with nut 35.

The words of each steel wire 34,36,37 are installed in this wise, the slotted hole 29A of the 1st pipe link 29 and sell between 30, the slotted hole 32A of the 2nd pipe link 32 and sell 30 between very close to each other, and by being screwed in the nut 35 on the sleeve pipe 34B, adjust the overhang of the steel wire main body 34A of left drg steel wire 34, until reaching such position, promptly by the effect of the spring force in the back drum brake 6, equalizer section 31 is bumped on the stop surface 14A of intermediate bracket 14.Like this, each several part does not produce and rocks phenomenon, and can make brake service the time to reply performance good.

Below, the action of brake equipment that each steel wire 34,36,37 has been installed by described order is described.

At first, hold right handles 3 and make its when revolution, then by right drg steel wire 36 along the direction of A shown in arrow tractive the 1st pipe link 29.Like this, pivoted lever 23 is just along the revolution of the direction of B shown in the arrow, by being installed in the pushing pin 33 on this pivoted lever 23, piston 20 is promoted along the arrow A direction, therefore by the braking liquid in these piston 20 pushing oil har openings 12, disc-brake 5 actions were braked front-wheel before this hydraulic pressure made.

At this moment, because the 1st pipe link 29, pushing pin 33 are connected on the 1st connecting rod connecting bore 25A that as the bolt insertion hole 24A that turns round fulcrum only is the closer distance of L1, L2, pin insert opening 25B, 26B, operational ton when therefore making right handles 3 revolutions, disc-brake 5 actions can be adjusted the braking force that gives front-wheel exactly before can intactly making.

On the other hand, when holding left handle 1 and making its revolution, then by left drg steel wire 34, along arrow A direction tractive equalizer section 31.Like this, equalizer section 31 tractive drgs drive steel wire 37 and make 6 actions of back drum brake, and trailing wheel is braked.

Again, during along arrow A direction tractive equalizer section 31, make pivoted lever 23 along the revolution of arrow B direction by the 2nd pipe link 32, promote piston 20 by pushing pin 33, disc-brake 5 actions are also braked front-wheel before making.

At this moment, because ratio with distance L 4 between steel wire connecting bore 31A and the steel wire connecting bore 31B and the distance L 5 between steel wire connecting bore 31A and the lever attachment hole 31C, be set at about 1: 2.7, the drg that therefore can be connected with bigger power tractive on the steel wire connecting bore 31B drives steel wire 37, gives trailing wheel big braking force by back drum brake 6.In addition, the 2nd pipe link 32 is carried out tractive according to described ratio with less power, and pivoted lever 23 is turned round along the arrow B direction.

Secondly, because ratio with the distance L 3 between the distance L 2 between bolt insertion hole 24A and pin insertion hole 25B, the 26B and bolt insertion hole 24A and the 2nd lever attachment hole 26A, be set at about 1: 1.8, when therefore making pivoted lever 28 revolutions, with the 1/1.8 stroke promotion pushing pin 33 of revolution this moment amount by the 2nd pipe link 32.

Therefore, during revolution operation left handle 1, because the effect of equalizer section 31, its operating effort can be reduced to about 1/2.7, but promote the power of pushing pin 33 on pivoted lever 23, because pin insert opening 25B, 26B and the 2nd lever attachment hole 26A, are increased to 1.8 times when turning round operation right handles 3 with respect to the distance relation of bolt insertion hole 24A, therefore disc-brake 5 actions can be braked front-wheel before can making complementaryly.

Below, the two-wheel car in running condition is for example described because of the leakage of the braking liquid in the oil har opening 12, preceding disc-brake 5 unsve situations.

At first, when holding left handle 1 under the state that the braking liquid in oil har opening 12 leaks and making its revolution, then, draw equalizer section 31 along the arrow A direction by left drg steel wire 34.At this moment, as shown in Figure 7, because pivoted lever 23 is free state, so this pivoted lever 23 turns round significantly along direction of arrow C, and the circular-arc teat 31D of equalizer section 31 just touches on the equalizer section stop surface 13B of preceding lateral bracket 18.

But, touch the state of equalizer section stop surface 13B from the circular-arc teat 31D of equalizer section 31, further make left handle 1 revolution, one side of equalizer section 31 is turned round along arrow D direction, and tractive drg steel wire 37, make 6 actions of back drum brake, can be to trailing wheel brake activation power.

Therefore, according to the brake for two-wheeled car of present embodiment, during revolution operation left handle 1, by back drum brake 6, can brake trailing wheel, meanwhile, by preceding disc-brake 5, can carry out complementary braking to front-wheel, even therefore when slowing down, only operate left handle 1, also can carry out suitable braking, be easy to carry out the operation of bar, and can obtain stable braking force front-wheel and trailing wheel.

In addition, before making by right handles 3 during disc-brake 5 action, disc-brake 5 actions before the operational ton of this right handles 3 can intactly make, so glancing impact can brake exactly to the front-wheel that bears load, can improve the stability of glancing impact.

Again, operation preferentially move back drum brake 6 during left handle 1, gives trailing wheel big braking force, by preceding disc-brake 5, front-wheel is carried out complementary braking, so glancing impact can make the trailing wheel braking earlier, at glancing impact vehicle body is stablized.

In addition, master cylinder cover 11 is utilized as cover itself, and piston 20, pivoted lever the 23, the 1st pipe link 29, equalizer section the 31, the 2nd pipe link 32, pushing pin 33 etc. have been installed integratedly, therefore can not adopt other cover to constitute brake equipment, can make cost reduction, brake equipment miniaturization.

And master cylinder cover 11 makes foundry goods by aluminium etc. and forms, and therefore can improve the rigidity of cover, even when when brake operating, bearing big load, also can suppress the distortion that causes because of this load, can carry out brake operating exactly, can improve operability and durability.

In addition, when being installed in pivoted lever 23 on the master cylinder cover 11, one side of this pivoted lever 23 pivotally is installed on the bar installation portion 16 of master cylinder cover 11, and with the 1st pipe link the 29, the 2nd pipe link 32, the pushing pin 33 concentrated opposite sides that are connected pivoted lever 23, therefore, can reduce pivoted lever 23 installing space on every side.

Again, clamp axes O-O with pivoted lever 23, one routine pivoting of length direction is bearing on the master cylinder cover 11, the overlapping equalizer section 31 that is equipped with above this pivoted lever 23 also simultaneously, therefore equalizer section 31 can be accommodated in the length range of pivoted lever 23, can reduce the installation dimension of left and right directions, make the integral miniaturization of brake equipment.

In addition, pivoted lever 23 is by installation portion 24, form fork-shaped from this installation portion 24 to the 1st bar portion 25 and the 2nd bar portion 26 of the front side of master cylinder cover 11, rear side elongation, to be configured in the front side independently with the operating system of left drg steel wire 34 operations, to be configured in rear side independently with the operating system of right drg steel wire operation, therefore, can effectively utilize the front and back of master cylinder cover 11, not only can make equipment miniaturization, and also have local each parts of installation more than needed, thereby the assembleability and the maintainability of device have been improved.

Be vertically disposed because promote the pushing pin 33 of piston 20, so when pushing pin 33 is installed in master cylinder cover 11 1 sides, can reduce axially (above-below direction) size with axes O-O again.

Again because the two-side supporting of pushing pin 33 in the 1st bar portion 25 and the 2nd bar portion 26 of pivoted lever 23, so can improve pivoted lever 23 torsion proof rigidity when operation, can improve its life-span and operating characteristic.

In addition, because the central portion at pushing pin 33 length directions is provided with the facial 33A of circular arc, even produce under the bevelled situations at pushing pin 33, also available pushing pin 33 is the straight vertically promotion of piston 20, can prevent to produce because of piston 20 damage that causes such as to block and move bad etc.

Again, even since braking liquid leakage etc. cause before disc-brake 5 when malfunctioning, draw equalizer section 31 with left handle 1, the circular-arc teat 31D and the equalizer section stop surface 13B of this equalizer section 31 are collided, just can make equalizer section 31 is that fulcrum turns round with this contact point, drive steel wire 37 by drg, just can make 6 brakings of back drum brake.Like this, just can slow down really, can guarantee safety from motoring condition.

And, the braking force that disc-brake 5 produces before during operation left handle 1, can mechanically set according to the ratio that each member is installed in the position on pivoted lever 23, the equalizer section 31, so just can easily be applied to various two-wheel cars by this ratio of suitable adjustment, can enlarge the Applicable scope of this brake equipment.

Again, on the tangent line when the axes O-O of piston 20 being positioned at make pushing pin 33 revolutions by pivoted lever 23, so when pivoted lever 23 being drawn and making it change vertically, pulling force at this moment can act on the piston 20 effectively by pushing pin 33, the braking force of disc-brake 5 before can increasing.

Embodiment is with the following example that is set at, be the distance L 2 between distance L 1, bolt insertion hole 24A and pin insert opening 25B, the 26B between bolt insertion hole 24A and the 1st lever attachment hole 25A, and the ratio of the distance L 3 between bolt insertion hole 24A and the 2nd lever attachment hole 26A is set at about 1: 1.8; Distance L 4 between steel wire connecting bore 31A and the steel wire connecting bore 31B, and the ratio of the distance L 5 between steel wire connecting bore 31A and the lever attachment hole 31C is set at about 1: 2.7.But the present invention is not limited to this, and also can be set at the value in the following ranges according to the factors such as distribution of the performance of vehicle, weight: the ratio of distance L 1, L2 and distance L 3 can be in 1: 1.3～1: 2.5 scope; The ratio of distance L 4 and distance L 5 can be in 1: 2～1: 3 scope.

But, by contacting part 121D and cover 111 states that touch mutually from equalizer section 121, further make left handle 101 revolutions, the other end of equalizer section 121 is turned round along arrow D direction, can draw the 2nd drg and drive steel wire 127, make 106 actions of back drum brake, can award rear-wheel braking force.

Like this, according to the present embodiment brake for two-wheeled car, when left handle 101 is turned round operation, award rear-wheel braking force by back drum brake 106, also can carry out complementary braking simultaneously,, also can carry out the appropriateness braking front-wheel and trailing wheel even therefore when slowing down, only operate left handle 101 by 105 pairs of front-wheels of preceding drum brake, carry out the bar operation easily, and can obtain stable braking force.

In addition, when drum brake 105 moves before making by right handles 103, drum brake 105 actions before the operational ton of this right handles 103 can intactly make, therefore, the front wheel brake power of bearing load can be awarded really at glancing impact, the stability of glancing impact can be improved.

Again, during operation left handle 101, back drum brake 106 preferentially moves, and awards the very big braking force of trailing wheel, and awards the complementary braking force of front-wheel by preceding drum brake 105, and therefore, glancing impact can make trailing wheel braking earlier, can make itself stable.

In addition, when being installed in pivoted lever 117 on the cover 111, one end of this pivoted lever 117 pivotally is bearing on the bar supporting slice 116 of cover 111, the 1st pipe link the 119, the 2nd pipe link the 122, the 1st drg is driven steel wire 126 concentrated being connected on the opposite side of pivoted lever 117, so can reduce the installing space around the pivoted lever 117, can make the brake gear integral miniaturization.

Again, during operation left handle 101, the braking force that preceding drum brake 105 is produced, be with respect to the ratio of the installation site of pivoted lever 117, equalizer section 121 and machinery is set according to each member, therefore, suitable this ratio of adjustment just can easily adapt to the needs of various two-wheel cars, can enlarge the range of use of this brake equipment.

Even under preceding drum brake 105 unsve situations, also can award rear-wheel braking force by operation left handle 101, therefore, under motoring condition, can slow down really, can guarantee safety.

On the other hand, owing to being carries out Bending Processing to the 1 Zhang Ping's plate that is cut into the regulation shape to make cover 111, pivoted lever 117, equalizer section 121 etc., thus can be easily and make these members cheaply, can improve production performance, reduce production costs.

Such as detailed above, according to a kind of brake for two-wheeled car of the present invention, by holding right handles and making its revolution, but just tractive the 1st pipe link, pivoted lever is rotated, the 1st transom that is connected on this pivoted lever just moves, by the action of the 1st transom, just braking force can be awarded front brake.At this moment, right handles is rotated and the pulling force that produces can be directly passed to the 1st transom by the 1st pipe link, therefore, can be directly with the operational ton of right handles front brake is moved, and glancing impact can make the front-wheel that bears load brake really, has improved the stability of glancing impact.

Again, by holding left handle and make its revolution, but just tractive equalizer section, side by being connected this equalizer section length direction or the 2nd transom on the either side in the opposite side just can award rear brake with braking force.Simultaneously, can make pivoted lever revolution,, braking force be awarded front brake so the 1st transom just correspondingly moves according to the revolution of this pivoted lever by the 2nd pipe link on the opposite side that is connected described equalizer section length direction.

According to another kind of brake for two-wheeled car of the present invention, by holding right handles and making its revolution, the 1st pipe link is pulled, make the pivoted lever revolution, by being connected piston, the pushing braking liquid in the promotion member promotion master cylinder cover on this pivoted lever, braking force can be awarded front brake by this brake fluid pressure.At this moment, the pulling force that directly the right handles revolution is produced from the 1st pipe link passes to piston, and therefore, the operational ton of right handles can directly make the front brake action, and glancing impact can make the front-wheel that bears load brake really, has improved the safety of glancing impact and has given birth to.

In addition, by holding left handle and make its revolution, but just tractive equalizer section by being connected the connector on this equalizer section length direction one side, awards rear brake with braking force.Simultaneously, can make the pivoted lever revolution by the 2nd pipe link that is connected equalizer section length direction opposite side, thus can be according to the revolution of this pivoted lever, and the piston by promoting in the member promotion master cylinder cover awards front brake with braking force.

Therefore,, also can award the suitable braking force of front and back wheel, make the processing ease of bar, and can obtain stable braking force even only operate left handle during deceleration.When operating left and right sides handle simultaneously, can will award front-wheel and trailing wheel with the corresponding braking force of the operating effort of each bar again.At this moment, though the power that power that is produced in left handle operation on the front-wheel and right handles operation are produced acts on front-wheel with the state of repeat function on pivoted lever, braking force is to produce according to the big side of strength, so also can not feel inharmonious on operating.

In addition, owing to, be to utilize, needn't establish the needed cover of these members of installation in addition as the master cylinder cover that installs back usefulness such as bull stick and connector to the cover of the master cylinder of front brake the supply system hydrodynamic pressure, but the simplified actuator structure helps cost-cutting and equipment miniaturization.

And, for example adopt the foundry goods of making by aluminium etc. to constitute the master cylinder cover, can improve rigidity, therefore, and the caused distortion of load in the time of can suppressing because of brake service, operational brake improves the operating characteristic of drg and life-span definitely.

Again, owing to pivoted lever is configured to clip the state of master cylinder cover axis, and this pivoted lever becomes parastate with equalizer section, with the 2nd pipe link the opposite side of pivoted lever length direction and the opposite side of equalizer section length direction are coupled together, therefore, can effectively utilize the width of master cylinder cover, and can therefore can reduce to install needed space in the axial direction with pivoted lever and equalizer section overlay configuration.

According to the present invention, the 1st pipe link, and the 1st pipe link is connected drg steel wire on the right handles etc. independently is provided in the 1st bar portion one side, equalizer section, the 2nd pipe link, and the 2nd pipe link is connected steel wire on the left handle etc. independently is provided in the 2nd bar portion one side, owing to can set like this,, can make whole brake gear miniaturization so can reduce the installing space of left and right directions.

Again for example, can be with the operating system separate configurations of being undertaken in master cylinder cover front side by left handle, the operating system that right handles is carried out independently is provided in master cylinder cover rear side, so can effectively utilize front, the back of master cylinder cover, can set parts effectively, make equipment miniaturization, but also can improve the assembleability and the maintainability of device.

According to the present invention, promoting member is to adopt pushing pin, and this pushing pin is provided on the direction with the axis normal of piston, therefore, can reduce pushing pin is assembled in the installing space of master cylinder cover one side, can make brake equipment miniaturization in the axial direction.

According to the present invention, the two supports of pushing pin is in the 1st bar portion and the 2nd bar portion of pivoted lever, so available pushing pin couples together the 1st bar portion and the 2nd bar portion, can improve the intensity of antitorque commentaries on classics between the 1st bar portion, the 2nd bar portion etc., can improve the life-span and the operating characteristic of brake equipment.

According to the present invention, for example owing to reasons such as braking liquid leakages, when making front brake be in unsve state, even under situation with left handle tractive equalizer section, also can make the opposite side of this equalizer section length direction touch the equalizer section stop surface, with this contact terminal is the side revolution that fulcrum makes the equalizer section length direction, and so just available left handle tractive is connected the connector on equalizer section length direction one side.So, braking force can be awarded rear brake, can slow down really from motoring condition, can guarantee safe reliability.

According to the present invention, equalizer section is touched under the state on the stopper element, can be to this equalizer section location, so improved operating efficiency when installing, make the labor efficiency raising.

According to the present invention, by using left handle tractive equalizer section, when making the pivoted lever revolution with the 2nd pipe link, in order to make this pivoted lever revolution then need the stroke bigger 1.3～2.5 times than the 1st pipe link, but can correspondingly make near the promotion member action of connection location that is located at the 1st pipe link with big strength, therefore, can provide required braking force, can improve braking potential to front brake.

According to the present invention, by with left handle tractive equalizer section, use the power bigger to make near the connection location that is connected left handle connector action than the 2nd pipe link, big braking force can be supplied with rear brake.At this moment,,, use the power littler to make the pivoted lever revolution, also can award braking force front brake than connector by being connected locational the 2nd pipe link doubly than the connection location of connector 2-3 far away at the opposite side of equalizer section length direction.Like this, just can be awarding rear brake than the bigger braking force that awards front brake, therefore, this rear brake can be braked in advance, has improved the stability of glancing impact.

According to another brake for two-wheeled car of the present invention, hold right handles and make its revolution, so the 1st pipe link is pulled, make the pivoted lever revolution, by being connected the piston in the promotion member promotion master cylinder on this pivoted lever, the pushing braking liquid can award front brake with braking force by this brake fluid pressure.At this moment, the 1st pipe link and promotion member are connected on the midway location of pivoted lever length direction, therefore, the pulling force that the 1st pipe link can be produced the right handles revolution almost directly sends the promotion member to, and the braking force that operational ton produced of right handles is directly supplied with front brake.Like this, the front-wheel that bears load is braked really, improved the stability of glancing impact at glancing impact.

Again, hold left handle and make its revolution, then tractive, the operation equalizer section, can braking force be awarded rear brake by the connector that is connected on this equalizer section length direction one side.Simultaneously, also can make the pivoted lever revolution, therefore, can braking force be awarded front brake according to the revolution of this pivoted lever, by the piston that promotes in the member promotion master cylinder by the 2nd pipe link that is connected on the described equalizer section length direction opposite side.

Like this,, also the braking force of appropriateness can be awarded front-wheel and trailing wheel, carry out the operation of bar easily, and can obtain stable braking force even only operate left handle during deceleration.In addition, when operating left and right sides handle simultaneously, also can provide and the corresponding braking force of the operating effort of each bar to front-wheel and trailing wheel.In this case, for front-wheel, though operation power that left handle produced and the operation power repeat function that right handles produced on pivoted lever, produce because braking force is a power according to the big side of strength, so also do not have inharmonic sensation on operating.

In addition, owing to the axis of the piston in the master cylinder is positioned at utilize pivoted lever to make to promote on the rotating tangent line of member, therefore, with pivoted lever when axially drawing and making its revolution, at this moment power just can act on the interior piston of master cylinder effectively, can increase the braking force of front brake.
