Description
Technical field
This utility model is related to the brake field of electro-tricycle, more particularly to the service brake system of scalable lever ratio.
Background technology
The brake of three-wheel back wheels of vehicle realizes that by brake disc the machine leader of brake disc is controlled by pull bar connection
End, control end are located at operator seat, and control end action is, by the low-angle relatively big-movement for being driven and realizing brake disc, usually to lead to
Cross in a control end even disk cam, the centre of gyration of disk cam is fixedly connected control end, namely control end control plate-like
Cam rotation, by the pull bar that is articulated and connected, pull bar drives brake disc action, more sensitive in order to obtain for the distal end of disk cam
Braking effect pull bar is generally connected to the distalmost end of disk cam, but as the service life of brake disc increases, reaches identical
The brake disc operating distance of braking effect is also slowly increasing, and thus causes new car and used car sensitivity difference is larger, pass
The solution of system is that the connection between pull bar and brake disc is made the structure that can be adjusted, namely the company of machine leader and pull bar
Contact can adjust and then wish to reach the adjustable effect of control sensitivity, although this method can solved in some cases
Brake failure is quick, but due to the movement locus of machine leader be around brake disc center rotating, therefore adjust certain length after, lead
Leader is affected to cause adjustable range be further added by by its movement locus, thus its regulating effect is limited, and traditional tune
Node is more hidden, it is not easy to be adjusted.
The content of the invention
For above-mentioned situation, the purpose for overcoming the defect of prior art, this utility model is just to provide a kind of regulation thick stick
The service brake system of bar ratio, it is therefore intended that brake disc regulating degree is limited in solving traditional tricycle, and adjust difficult problem.
Its technical scheme is that, including the brake disc coordinated with three-wheel back wheels of vehicle, the machine leader of each brake disc is cut with scissors respectively
It is connected to pull bar, the pull bar is connected to disk cam, the basic circle end of disk cam down and is provided with through hole, in the through hole
It is cased with a cannulated sleeve, the contact position annular solder of cannulated sleeve and disk cam is fixed, fixed on the periphery wall of the sleeve
Service brake pedal is connected with, service brake pedal tilts upward bending, and the bending section of service brake pedal is provided with alignment pin, the bias of disk cam
End is provided with the revolution of connecting hole corresponding with tie rod end, the connecting hole at least two, each connecting hole and disk cam
It is centrally located on same straight line, between the eccentric end of disk cam and car body, is connected with back-moving spring, the back-moving spring and foot
Pedal of stopping is located at disk cam not homonymy, forms service brake pedal upset disk cam and rotates at service brake pedal and tense reset bullet
The structure of spring.
The brake disc has two, and brake disc is coordinated with trailing wheel respectively, and the machine leader of each brake disc connects drawing respectively
Bar, each pull bar connect drive link, the drive link is respectively arranged at two ends with driving cam, and driving cam is distally-oriented to lower section
And be hinged with the end of pull bar, actuating cam is provided with the middle part of the drive link, the distal end connection transiting rod of actuating cam is described
The transiting rod other end is hinged with connecting hole.
Connection between pull bar of the present utility model and connecting hole can be adjusted, and control-rod is with pull bar with regard in basic circle
The lever ratio of the heart can be adjusted with gold letter, and the effect for being played is that its adjusting position is located at operator seat and adjusts enhanced convenience, separately
Its regulation can carry out classification according to the distance between connecting hole and be adjusted, and regulation is restricted less.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is schematic top plan view of the present utility model.
Specific embodiment
Specific embodiment of the present utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment one：As depicted in figs. 1 and 2, the service brake system of scalable lever ratio, including coordinating with three-wheel back wheels of vehicle
Brake disc 1, the machine leader 7 of each brake disc 1 have been respectively articulated with pull bar 2, and the pull bar 2 is connected to disk cam 3, disk
The basic circle end of shape cam 3 down and is provided with through hole, is cased with a cannulated sleeve 4, cannulated sleeve 4 and disk cam 3 in the through hole
Contact position annular solder fix, be fixedly connected with service brake pedal 5 on the periphery wall of the sleeve, service brake pedal 5 is tilted upward
Bending, the bending section of service brake pedal 5 are provided with alignment pin, and the eccentric end of disk cam 3 is provided with connecting hole corresponding with 2 end of pull bar
6, the connecting hole 6 at least two, each connecting hole 6 are located along the same line with the centre of gyration of disk cam 3, and plate-like is convex
Back-moving spring is connected between the eccentric end of wheel 3 and car body, and it is different that the back-moving spring is located at disk cam 3 from service brake pedal 5
Side, forms service brake pedal 5 and overturns the structure that disk cam rotated and tensed back-moving spring at service brake pedal；The brake disc 1
There are two, brake disc 1 is coordinated with trailing wheel respectively, the difference cylinder lever connecting rod 2 of machine leader 7 of each brake disc 1, each pull bar 2
Connection drive link 8, the drive link 8 are respectively arranged at two ends with driving cam 9, driving cam 9 be distally-oriented to lower section and with pull bar 2
End be hinged, the middle part of the drive link 8 is provided with actuating cam 10, and the distal end connection transiting rod 11 of actuating cam 10 is described
11 other end of transiting rod is hinged with connecting hole 6.
Transiting rod when new car is assembled as brake disc is sensitiveer, can be connected when specifically used by this utility model
It is connected to apart from the nearer connecting hole of basic circle, by need to only dubbing service brake pedal brake disc so when service brake is carried out, carries out action,
Brake is realized, after brake disc is using a period of time, machine leader needs bigger displacement realize brake, at this moment
Only the connection end of transiting rod need to be attached with connecting hole farther out, its adjusting position is, with operator seat, conveniently to carry out
Adjust, it is easy to use.
Connection between pull bar of the present utility model and connecting hole can be adjusted, and control-rod is with pull bar with regard in basic circle
The lever ratio of the heart can be adjusted with gold letter, and the effect for being played is that its adjusting position is located at operator seat and adjusts enhanced convenience, separately
Its regulation can carry out classification according to the distance between connecting hole and be adjusted, and regulation is restricted less.
