Problems solved by technology

[0003] Before using the current electric bicycle braking performance testing machine, it is necessary to manually cooperate with the corresponding lifting equipment to place the electric bicycle on the testing machine, and the testing machine itself cannot improve the corresponding assistance, which reduces the functionality of the testing machine; Moreover, when the current electric bicycle braking performance testing machine fixes the rear end of the electric bicycle, the operator often needs to manually fix the electric bicycle, which is very inconvenient, and cannot automatically fix the electric bicycle after the electric bicycle is moved to the test stand , thereby reducing the convenience of using the electric bicycle braking performance testing machine; at the same time, when the electric bicycle wheel is rotating at high speed, the wheel of the electric bicycle may be unstable, and it cannot be fixed after the electric bicycle is fixed on the test stand. , Automatically improve the stability of the high-speed rotation of the electric bicycle wheel

Embodiment 1

[0039] Example 1, such as Figure 1-8 As shown, dry braking performance test:

[0040] A. For hand-operated brakes, apply a vertical force sufficient to prevent the tires from slipping on the rollers on the bicycle. After accelerating the driving mechanism to the specified speed, apply a series of operating forces with increments of 20N from 40N until 180N or The operating force required to achieve a braking force of at least 700N, whichever is less. However, if the wheels are locked, any possible brake overloading is activated, or the brake levers are in contact with the handlebars, no additional operating force is applied. For each operating force, three tests shall be performed within 1 min. Allow the brakes to cool down for 1 min before applying the next operating force;

[0041] B. For reverse brakes, apply a vertical force sufficient to prevent the tires from slipping on the rollers on the bicycle. After accelerating the driving mechanism to the specified speed, apply...

Embodiment 2

[0044] Example 2, such as Figure 1-8 As shown, when performing the wet braking performance test, in addition, the water spray system should be started in advance to spray the brake system no less than 5 seconds before braking, and the water should be continuously sprayed until the end of the test period. : Fix the bicycle on a special machine and increase the counterweight, drive the bicycle to the specified speed, apply the operating force on the brake handle or pedal until the operating force can make the braking force reach 200N±10%, and maintain this force At least 2.5s and record, repeat this procedure of the above-mentioned measured operating force ± 5% 10 times, or more times if necessary, until the average braking force of any one of the last 3 tests and the average braking force of the 3 tests The deviation does not exceed ±10%.

[0045] Working principle: Connect the device to the power supply before use, firstly control the two sets of electric lifting rods 3 to g...

Abstract

The invention discloses an electric bicycle brake performance testing machine which comprises a mounting table, a mounting frame is mounted at the top of the mounting table, a second connecting plate is hinged to the top of one side of the mounting table, and a first connecting plate is hinged to the side, away from the mounting table, of the second connecting plate. Clamping pin assemblies are symmetrically arranged at the two ends of the sides, close to each other, of the tops of the first connecting plate and the second connecting plate. Two sets of electric lifting rods are controlled to extend gradually, a first connecting plate and a second connecting plate are forced to turn outwards gradually, then an operator fixes a hook to the front end or the rear end of the electric automatic vehicle manually, then a driving motor is controlled to drive a winding roller to rotate, and a pull rope is wound slowly through the winding roller; in the process, the electric bicycle can be automatically pulled to the top of the mounting table without being matched with a lifting machine, the operation is simple and convenient, and the functionality of the electric bicycle brake performance testing machine is improved.

Description

technical field [0001] The invention relates to the technical field of electric bicycle testing equipment, in particular to an electric bicycle braking performance testing machine. Background technique [0002] Because of its affordable price, environmental protection, and lightness, electric bicycles are popular among many people, especially environmentalists. Electric bicycles are very popular in China. People from the elderly to teenagers basically ride electric bicycles. Just like cars, electric bicycles There is also a brake system, which transmits the braking force to the brake through the brake line through the action of the brake handle, and the brake tightly clamps the wheel to achieve the purpose of braking. [0003] Before using the current electric bicycle braking performance testing machine, it is necessary to manually cooperate with the corresponding lifting equipment to place the electric bicycle on the testing machine, and the testing machine itself cannot im...
