V: V is V through the brake brake brake caliper brake rim to holdDisc: disc brake caliper through (or caliper) in a steel disc brake is fixed on the drum.Disc brake with "V" is by force on the object, and the friction speed decreased. The biggest difference between them is that the "V" brake is...Through the brake block of bicycle brake ring, disc brake is specially provided with brake disc, brake caliper brake by friction in the pressure on the brake to brake.
The main difference between the two brake is the transmission medium. Pull the line disc brake line tension, to produce brake disc; hydraulic disc brake through the oil on the oil pipe pressure oil to drive brake brake disc. So, pull brake line and we usually use the most common "V". The principle is similar. In addition to the brake disc and the skin, two remaining basic things in general. While the hydraulic brake is different, hydraulic disc brake of the brake caliper is tubing and a complete set of products with.Performance appraisal line pull brake and hydraulic disc of the two1. line pull brake disc, because of its power is on the brake line to transfer, so will be unable to avoid the same and 'V' weakness: because.The length of the line itself, the elasticity, and the shell friction and other factors, and the loss of the braking force, resulting in insufficient braking. The above disadvantages can be solved by replacing the brake line and maintaining the line in the brake line.
Disc typeExercise bicycle disc brake, mainly divided into two types, one is line Diesha (Mechanical), a hydraulic disc.1. line pull on the brake disc, brake calipers allow the pull of the line within the (brake) and clamp the friction disc, brake effect;2. hydraulic disc, using oil as medium, by moving inside the piston to compress oil on the brake force, pressure from the pipeline through the caliper, pushing the piston in the brake caliper, drives the clamping disc.
2. hydraulic disc brake, the transmission system used for oily substances (common object, used for DOT standard oil, mineral oil. The DOT-3 or DOT-4 is the vehicle brake oil disc special ingredients, is to overcome the characteristics of thermal expansion and contraction, but the substance is toxic, corrosive, can dissolve paint, good will absorb water. Mineral oil, its composition is very pure, although non-toxic, but it will not absorb moisture, paint can not wash. The utility model has the advantages that the braking force can not be diminished when the utility model is used for a long time or encounters high temperature. ) because of the use of oily objects in the transmission process is first to ensure the sealing property, so the hydraulic disc will be lost in the transmission process of the minimum power. At the same time, compared with the line pipe, the oil object in the pipeline transmission process, than the brake line in-line pipe transmission friction is smaller, so as to effectively reduce the kinetic energy loss, and enhance the braking force. The performance of the two, the biggest is not because of its different driving material, but because of its different braking effect. Pull the line disc because these factors caused the loss of strength resulting in hydraulic disc brake performance attenuation, because of the loss of power in transmission and the minimum brake performance increases, while the decreasing of friction brake also provides a good feel (with very relaxed intensity of the braking effect is achieved great).
