A kind of motor-tricycle holding brake device
One, technical field
The utility model relates to a kind of motorcycle brake device, exactly is a kind of motor tricycle vehicle brake.
Two, background technology
At present, the elderly is by being installed in the hand braking handle on the vehicle frame with the motor-tricycle braking during standstill, acts on trailing wheel through lever connection and realizes braking, and this kind brake mode is installed complicated, destroys the motor-tricycle outer covering piece, influences the attractive in appearance of vehicle modeling.
Three, summary of the invention
The purpose of this utility model is to provide a kind of can overcome above-mentioned defective, installs simply, easy to operate, can reliably realize the motor-tricycle holding brake device of braking function.
For reaching above purpose, the utility model has been taked following technical scheme: a kind of motor-tricycle holding brake device mainly is made up of torsion spring, bar handle, ratchet, ratchet, support, brake pedal, it is characterized in that, the torsion spring both arms are inserted into respectively on ratchet and the support, ratchet and brake pedal are that an integral body is rack-mount jointly, bar handle connects with support by axle sleeve with the ratchet seam, described torsion spring is centering spring not, and torsion spring double-walled installation site is provided with the dead point.
By above setting, when needing braking during standstill, the slewing maneuver handle, when turning over the dead point of torsion spring, elastic force by torsion spring makes ratchet and ratchet positive engagement, at this moment steps on brake pedal, utilizes the anti-reverse of ratchet to transfer to reliable braking, make Parking reliable, light, reach the purpose of safe Parking.
Four, description of drawings
Now in conjunction with the accompanying drawings the utility model is further described
Fig. 1 is the utility model integral structure scheme drawing
Fig. 2 is the utility model birds-eye view
1 torsion spring, 2 bar handles, 3 ratchets, 4 ratchets, 5 supports, 6 brake pedals among the figure
Five, the specific embodiment
As shown in Figure 1 and Figure 2, torsion spring 1 one arms are inserted on the support 5, another arm is inserted on the ratchet 3, the pawl axis seam is formed by ratchet 3 and bar handle 2 seam, and bar handle 2 is sleeved in the axle sleeve on the support, ratchet 4 be an integral structure with brake pedal 6, and be sleeved on the support spool on.Because ratchet 3 is welded together with bar handle 2, when bar handle 2 turns of pawl axis seam, ratchet 3 rotates thereupon, rotates thereby drive torsion spring 1, because an arm of torsion spring 1 is inserted on the support 5, this wall is promptly as the centre of gration of torsion spring 1, when turning over the dead point of the torsion spring of not feeling relieved, lean on the elastic force of spring to make ratchet 3 and ratchet 4 positive engagement, at this moment step on brake pedal 6, utilize the anti-reverse of ratchet 3 to transfer to, reach the purpose of safe Parking with reliable braking.When brake off, only need step on brake pedal 6 slightly, bar handle 2 is rotated in the opposite direction, same when turning over the dead point of the torsion spring of not feeling relieved, the elastic force of spring makes ratchet 3 separate fully with ratchet 4, does not play the Parking effect.
