Abstract
The utility model provides a manual brake system of adjustable lever ratio, solve traditional tricycle in 1 regulation degree of brake disc limited, and adjust the problem of difficulty, include with tricycle rear wheel complex brake disc, each the brake disc lead that leading chip is articulated respectively to have a pull rod, the pull rod transmission is connected to the disc cam, and the base circle of disc cam is held and just is equipped with the through -hole up, the through -hole endotheca has a hollow sleeve, and the contact department annular welding of hollow sleeve and disc cam connects fixedly, fixedly connected with hand brake lever on the telescopic periphery wall, the eccentric end of disc cam is equipped with the connecting hole that corresponds with the pull rod tip, the connecting hole is at least two, each the connecting hole is located same straight line with the centre of turning circle of disc cam, the utility model discloses the regulation can be graded according to the distance between the connecting hole and adjusted, and it is less that the regulation receives the restriction.
Description
Technical field
The utility model is related to the brake field of electro-tricycle, more particularly to can adjust the hand brake system of 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, the utility model is just to provide a kind of regulation thick stick
The hand brake system of bar ratio, it is therefore intended that 1 regulating degree of brake disc is limited in solving traditional tricycle, and adjust difficult asking
Topic.
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 upward 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
It is connected with hand brake lever, the eccentric end of disk cam is provided with connecting hole corresponding with tie rod end, the connecting hole at least two, respectively
The connecting hole is located along the same line with the centre of gyration of disk cam.
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 hand brake system of lever ratio is can adjust, including coordinating with three-wheel back wheels of vehicle
Brake disc 1, the brake disc 1 have two, and brake disc 1 is coordinated with trailing wheel respectively, and the machine leader 7 of each brake disc 1 connects respectively
Connect pull bar 2, each pull bar 2 connects drive link 8, drive link 8 is connected to disk cam 3, the basic circle end of disk cam 3 upward and
Through hole is provided with, a cannulated sleeve 4 in through hole, is cased with, cannulated sleeve 4 is annular with the contact position of disk cam 3, to the contact position
Annular solder is carried out, the length of cannulated sleeve 4 so can be distinguished in the both sides of disk cam 3 more than the thickness of disk cam 3
Carry out annular solder, connection is more reliable, on the periphery wall of the sleeve, be fixedly connected with hand brake lever 5, disk cam 3 it is inclined
Heart end is provided with connecting hole 6 corresponding with 2 end of pull bar, the connecting hole 6 at least two, each connecting hole 6 and disk cam 3
The centre of gyration be located along the same line, the drive link 8 is respectively arranged at two ends with driving cam 9, and driving cam 9 is distally-oriented to
Lower section and it is hinged with the end of pull bar 2, the middle part of the drive link 8 is provided with actuating cam 10, the distal end connection of actuating cam 10
Transiting rod 11,11 other end of the transiting rod are hinged with connecting hole 6.
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.
