Problems solved by technology

Leading shoe brake is the most common drum brake structure. Whether the car is braking in the forward or reverse state, one of the two brake shoes of the brake is always the leading shoe and the other is the following shoe, so the braking is stable. It has good performance and is easy to install the parking brake mechanism. However, no matter what the braking state is, there is always one brake shoe as the slave shoe. bad brakes
However, due to the

Abstract

The invention discloses a leading trailing shoe drum brake applying force through trailing shoe giant magnetostictive and a method of the leading trailing shoe drum brake. The leading trailing shoe drum brake comprises a left brake shoe, a left brake piece, a brake wheel cylinder, a brake drum, a right brake piece, a right brake shoe, a reset spring, a right connection piece, a right limiting cover, a right coil fixing cover, an assistor shell, an assistor base, a left coil fixing cover, a left limiting cover, a left connection piece, a left elastic rubber gasket, a left adjusting spacer, a left wire outlet hole, a giant magnetostictive column, an exciting coil, a coil framework, a right wire outlet hole, a right adjusting spacer and a right elastic rubber gasket. According to the leading trailing shoe drum brake applying force through trailing shoe giant magnetostictive and the method of the leading trailing shoe drum brake, to solve the problem that a trailing shoe in a leading trailing shoe brake is low in braking efficiency, the giant magnetostictive column is utilized to conduct braking and force applying on the trailing shoe, so that the overall braking efficiency of the leading trailing shoe drum brake is improved, the braking distance is reduced, and vehicle running safety is improved; besides, the leading trailing shoe drum brake further has the advantages that the drum brake is good in reliability, convenient to use and free of affecting working of an original braking system after reformation is conducted, and a parking braking mechanism is arranged conveniently.

Description

technical field [0001] The invention relates to a drum brake, in particular to a drum brake with a leading shoe and a method thereof with super magnetostrictive force applied from the shoe. Background technique [0002] Drum brakes are one of the most common types of brakes and are widely used in automobiles, especially medium and heavy commercial vehicles. Compared with disc brakes, drum brakes have the advantages of low production cost, long life of brake shoes, good dust and anti-fouling performance, and good reliability. At the same time, thanks to its own structural characteristics, most drum brakes have a self-amplification effect using the rotation of the brake drum, which can effectively improve the braking effect; in terms of parking brake arrangement, it is also relatively Simpler and more reliable. [0003] During the braking process, if the friction force between the brake shoe and the brake drum can make the brake shoe press tighter, that is, the friction torq...
