How does small road roller prevent skid?

Single steel wheel roller, double steel wheel roller brake failure, its performance phenomenon is: single steel wheel roller, double steel wheel roller stopped on the ramp to slide phenomenon.

Firstly, from the single steel wheel roller, double steel wheel roller parking brake system composition, structure and working principle, single steel wheel roller, double steel wheel roller in the rear axle and front wheel reducer is used in the disc brake, it produces braking force is dependent on the friction between the friction sheet; The parking brake failure may be caused by the skid of the brake friction plate. The braking torque of the brake depends on the number of surfaces of the friction plate, the average radius of the friction plate and the size of the friction force. The number and average radius of the friction plate are designed and manufactured and can not be changed during the braking process.

Then, the brake skid must be caused by the reduction of friction force. The reason can be analyzed and corresponding measures can be taken to solve it. The slippage caused by the reduction of friction force of small roller friction sheet can be solved by replacing a new friction sheet.

The compression force of the brake disc of single steel roller and double steel roller is generated by the compression spring. If the compression spring decreases due to the plastic deformation caused by fatigue or heat, the compression performance of the compression spring decreases. If the brake friction plate becomes thinner after wear, the compression spring extends, according to the compression spring force and its free length is inversely proportional, so the spring elasticity will decrease. Causing the brake to slip.

The friction force of the friction brake depends on the pressure of the pressure disc and the friction coefficient of the friction plate. Brake friction plate should have a large friction coefficient, if the friction plate used for a long time, the friction surface ablative hardening, oil or water, will make the friction coefficient reduced, resulting in the brake skid.

Through the above analysis, there are two reasons for brake skid: first, the friction of the friction sheet of the small roller decreases. Second, the compact force of the brake disc of the small roller is reduced. When analyzing the cause of the fault of the roller, it can also be found while analyzing to gradually reduce the scope of suspicion until the cause and position of the fault are confirmed. Find the cause of the problem, the remedy, the problem will be solved.
