Problems solved by technology

Since the size of the area of ​​the friction plate has nothing to do with the braking force, the structure of the large-area friction plate adopted by the current brake shoe is meaningless, and the structure of the large-area friction plate can only be a waste of the friction plate. material, making the cost of brake shoes higher

Embodiment Construction

[0028] figure 2 A first embodiment of the brake shoe construction of the present invention for use in brakes of three-wheeled vehicles and other vehicles is shown. According to the figure, it includes a metal shoe 41 and a friction plate 42, and the metal shoe 41 and the friction plate 42 are riveted. The arc length of the friction plate in this embodiment is 14.9 centimeters, the width of the friction plate is 3.5 centimeters, 14.9×3.5=52.15 square centimeters, the arc area of ​​the friction plate is 52.15 square centimeters; the arc length of the metal shoe is taken as 29.8 cm, the thickness of the metal shoe is 3.5 cm, 29.8×3.5=104.3 square centimeters, the arc area of ​​the metal shoe is: 104.3 square centimeters; The arc area of ​​the friction plate accounts for 50% of the arc area of ​​the metal shoe.

[0029] Compared with the prior art, this embodiment is essentially that the arc area of ​​the friction plate is smaller than the arc area of ​​the metal shoe, that is, ...

Abstract

The invention relates to a brake shoe structure used for brakes of three-wheeled vehicles and other vehicles, in particular to a brake shoe in a drum brake. The brake shoe structure comprises a metal shoe piece and a friction piece which are in fixed connection. The brake shoe structure is characterized in that the friction piece is smaller than the metal shoe piece due to the fact that size of mutual contact area of the friction piece and the drum brake is relative with braking force. The brake shoe structure reduces cost by means of the friction piece scheme, is suitable for being installed in drum brakes of the three-wheeled vehicles and is suitable for being installed in the drum brakes of various vehicles.

Description

technical field [0001] The present invention relates to braking systems of vehicles, and in particular to brake shoes in drum brakes. Background technique [0002] At present, the structure of the brake shoe in the wheel brake (brake drum type) of the vehicle generally includes two parts, a metal shoe and a friction plate, which are fixedly connected between the metal shoe and the friction plate. The current brake shoes all use large-area friction plates. The percentage of the arc area of ​​the friction plate to the arc area of ​​the metal shoe is generally about 60% to 80%, and some even exceed 80%. It has been found that the smallest This percentage is 55.034%, and there is no brake shoe structure in which the percentage of the arc area of ​​the friction plate to the arc area of ​​the metal shoe is less than 55.034%. [0003] The brake shoe is a part of the wheel brake of the vehicle. In general, the enterprises that manufacture the vehicle do not directly manufacture the...
