When matched with the entire motorcycle, the rear brake assembly has the advantages of attractive and harmonious appearance, fast and power-saving brake, low power loss and reliable brake performance.
Description
Technical field
The present invention relates to a kind of motor bike member, specifically, relate in particular to brake assembly behind the motorcycle hydraulic disc type.
Background technology
At present, be installed in back brake assembly on the motor bike generally by component set-ups such as brake pedal, drag-line mechanism, main pump, lubricating cup, wheel cylinder and brake discs, wherein wheel cylinder is installed in the next door of brake disc, this wheel cylinder is connected with the oil outlet of main pump by first oil pipe, the oil inlet of main pump joins by second oil pipe and lubricating cup, and the push rod of main pump is connected with brake pedal by drag-line mechanism.When chaufeur tramps with one's feet moving brake pedal, brake pedal drives the push rod of main pump by drag-line mechanism, make the push rod retraction of main pump, hydraulic oil in the brake main pump is produced pressure, oil pressure in the brake main pump passes to wheel cylinder by oil pipe, the friction lining that promotes wheel cylinder is close on the brake disc, thereby the rear-wheel hub of captiveing joint with brake disc is stopped the rotation.Because be to adopt drag-line mechanism to transmit braking force in the conventional confguration, the transmission arm of force of drag-line mechanism is little, and the distance of transmission of power is longer, power waste is big, relatively requires great effort during brake operating like this, and the reliability of braking is guarantee not.Simultaneously, the ground clearance of drag-line mechanism is less, enters silt easily, thereby causes the drag-line clamping stagnation, and one side is operated dumb, is difficult to return after the braking on the other hand, has more serious potential safety hazard.In addition, main pump all is that level is installed in the conventional confguration, and lubricating cup is subjected to the restriction of installation site, and the oil outlet of its bottom is a little more than the oil inlet of main pump, and it is slower that the interior hydraulic oil of lubricating cup enters the speed of main pump and wheel cylinder like this, also can influence the reliability of braking.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of flexible, failure-free rear brake assembly of motorcycle.
Technical scheme of the present invention is as follows: a kind of rear brake assembly of motorcycle, comprise brake pedal, main pump, lubricating cup, wheel cylinder and brake disc, wherein wheel cylinder is installed in the next door of brake disc, this wheel cylinder is connected with the oil outlet of main pump by first oil pipe, the oil inlet of main pump joins by second oil pipe and lubricating cup, its key is also to comprise rear arm assembly, pull bar and front arm, the push rod of described main pump is hinged by the rear end of rear arm assembly and pull bar, the front end of this pull bar is articulated in the lower end of front arm, and the upper end of front arm and the afterbody of brake pedal are hinged.
The present invention adopts rocking arm rod-pulling type structure to replace traditional drag-line mechanism and transmits braking force, and by increasing the transmission arm of force and reducing because of long distance and directly transmit the power that loses, more flexible when making brake operating, laborsaving, the reliability of braking is secure; Simultaneously, eliminated the potential safety hazard that conventional confguration exists because of the return difficulty.
For simplified structure, the convenient installation, and further improve the reliability of brake-force transmission, above-mentioned rear arm assembly is made of first rear arm and second rear arm, wherein the rear end of the lower end of first rear arm and pull bar is hinged, the upper end of first rear arm is articulated in the front end of second rear arm, the bottom of the rear end of described second rear arm and main pump push rod is hinged, and the main pump push rod is vertical state.
The oil outlet of above-mentioned lubricating cup bottom is higher than the oil inlet of main pump, and diff-H between the two is 100～200mm.Above structure makes that the hydraulic oil gravitate in the lubricating cup is more obvious, and the speed that enters main pump and wheel cylinder is faster, also can play to guarantee that braking is flexible, the effect of reliability.
Beneficial effect: attractive in appearance, the coordination of the present invention and car load coupling, glancing impact is flexible, laborsaving, and power waste is little, and deceleration and stopping performance is reliable.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the arrangement plan of the present invention on motor bike.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples:
As shown in Figure 1 and Figure 2, the present invention is by component set-ups such as brake pedal 1, main pump 2, lubricating cup 3, wheel cylinder 4, brake disc 5, first oil pipe 6, second oil pipe 7, pull bar 8, front arm 9, first rear arm 10 and second rear arms 11, wherein brake pedal 1 is positioned at the next door of stretcher 12, the upper end of the afterbody of this brake pedal 1 and front arm 9 is hinged, front arm 9 is the upper end and distributes at top rake in back, lower end, and the front end of the lower end of front arm 9 and pull bar 8 is hinged.The lower end of the rear end of described pull bar 8 and first rear arm 10 is hinged, and first rear arm 10 parallels with front arm 9 substantially, and the upper end of first rear arm 10 is articulated in the front end of second rear arm 11, and the bottom of the rear end of second rear arm 11 and main pump push rod 2a is hinged.
As can be known, described main pump 2 is installed on the middle part of vehicle frame from Fig. 1, Fig. 2, and is vertical distribution.The oil inlet of main pump 2 is connected with lubricating cup 3 by second oil pipe 7, and lubricating cup 3 also is installed on the vehicle frame, and the oil outlet of lubricating cup 3 bottoms is higher than the oil inlet of main pump 2, and diff-H between the two is 100～200mm.The oil outlet of described main pump 2 is connected with wheel cylinder 4 by first oil pipe 6, and wheel cylinder 4 is positioned at the next door of brake disc 5, and is installed on the back vent person in charge 13 by support.Described brake disc 5 is captiveed joint with rear-wheel hub.
Principle of work of the present invention is as follows:
When chaufeur tramps with one's feet moving brake pedal 1, brake pedal 1 drives front arm 9 and rotates counterclockwise, front arm 9 spurs pull bar 8 forward, when first rear arm 10 is rotated counterclockwise, driving second rear arm 11 clockwise rotates, second rear arm 11 promotes the push rod 2a upward movement of main pump 2, make it to bounce back with respect to the pump housing, hydraulic oil in the main pump 2 is produced pressure, the hydraulic oil that flows in the main pump 2 from lubricating cup 3 by second oil pipe 7 under the effect of main pump push rod 2a, flows to wheel cylinder 4 by first oil pipe 6 like this, the friction lining that promotes wheel cylinder 4 is close on the brake disc 5, thereby the rear-wheel hub of captiveing joint with brake disc 5 is stopped the rotation.After the power disappearance that acts on the brake pedal 1, under the effect of oil pressure, each parts resets.
