The utility model aims at providing an electric tricycle braking system to solve at least one of the problem that exists among the foretell prior art.
The utility model adopts the following technical scheme:
a brake system of an electric tricycle comprises a frame and a foot brake pedal lever hinged on the frame, wherein one end of the foot brake pedal lever is fixedly connected with a connecting part, the connecting part is hinged with one end of a brake pull rod, the other end of the brake pull rod is hinged with a brake cable connecting piece, the brake cable connecting piece comprises a limiting groove in the middle and brake cable mounting holes on two sides, a limiting column is arranged in the limiting groove, and the limiting column is fixedly connected to the bottom of the frame; the brake cable mounting hole is 2, is connected with the one end of a brake cable in every brake cable mounting hole respectively, and the other end of brake cable is connected with rear wheel hub.
Furthermore, the middle part cover of brake cable is equipped with the stop collar that prevents the brake cable and bend, the one end and the rear wheel hub of stop collar are connected.
Furthermore, the middle part of the brake cable is fixedly connected with a limiting sheet matched with the limiting sleeve for use.
Furthermore, the brake cable connecting piece is T type.
The utility model has the advantages as follows:
1. the utility model discloses a linkage structure of brake pull rod and brake cable has shortened the length of brake cable, and the number of times of turning has reduced the resistance of brake cable self and the deflection on the brake cable, makes the brake effect better and stable, and braking system arranges more neatly moreover.
2. The utility model discloses a middle part cover of brake cable is equipped with the stop collar that prevents the brake cable from bending, can prevent that the brake cable from bending and making the resistance of increase brake cable self, influences braking system's brake effect.
3. The utility model discloses a brake cable connection piece is the T type, and the middle part is equipped with the spacing groove, and the spacing inslot is equipped with spacing post, and this structure can play the guide effect, makes the displacement of two brake cables the same, can guarantee two rear wheels and brake in step, avoids the phenomenon of stopping partially to produce.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is an enlarged schematic view of the structure at a in fig. 1.
Shown in the figure: 1-foot brake pedal lever, 2-connecting part, 3-brake pull rod, 4-brake cable connecting piece, 401-brake cable mounting hole, 402-limiting groove, 5-limiting column, 6-brake cable, 7-limiting sleeve, 8-limiting piece and 9-rear wheel hub.
Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention more clearly understood, the present invention will be described in further detail with reference to the accompanying drawings and detailed description. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.
The technical solution of the present invention is further explained with reference to fig. 1 to 2.
The utility model provides an electric tricycle braking system, includes the frame and articulates foot brake pedal lever 1 on the frame, the one end fixedly connected with connecting portion 2 of foot brake pedal lever 1, connecting portion 2 are articulated with brake pull rod 3's one end, and brake pull rod 3's the other end articulates there is brake cable connection piece 4, and brake cable connection piece 4 is the T type, and brake cable connection piece 4 includes the spacing groove 402 at middle part and the brake cable mounting hole 401 of both sides, is equipped with spacing post 5 in the spacing groove 402, and 5 fixed connection of spacing post are in the frame bottom. The brake cable mounting hole 401 is 2, is connected with the one end of a brake cable 6 in every brake cable mounting hole 401 respectively, and the other end of brake cable 6 is connected with rear wheel hub 9. The middle part cover of brake cable is equipped with stop collar 7 that prevents brake cable 6 and bend, and the one end and the rear wheel hub 9 of stop collar 7 are connected. The middle part of the brake cable 6 is also fixedly connected with a limiting sheet 8 which is matched with the limiting sleeve 7 for use.
The working process of the utility model is as follows:
when stepping on foot brake pedal lever 1 downwards, connecting portion 2 drives brake pull rod 3 and brake cable connection piece 4 and moves to the right side together, and brake cable connection piece 4 is with two brake cables 6 pulling to the right side together, and brake cable 6 removes in stop collar 7 this moment, and spacing piece 8 separates with stop collar 7, and the external brake block of 6 tip of brake cable pastes tight two rear wheel hubs 9 and accomplishes the rear wheel brake operation. When the foot brake pedal lever is loosened, the brake cable moves leftwards through the elasticity of the external spring, and the brake cable 6 stops moving when the limiting sheet 8 is in compression joint with the limiting sleeve 7.
