The invention discloses an adjustable brake assembly which comprises an axle rod and an axle housing provided with a brake shoe, and further comprises a rotatably arranged brake drum, notches are formed in the circumference of the inner wall of the brake drum, and arc blocks are movably arranged in the notches. According to the adjustable brake assembly, the middle shoe is actively attached to the arc block in the rotating state by slightly stepping the pedal, sliding friction is generated for speed reduction of the brake drum, when speed reduction or braking is needed again after speed reduction, the pedal is forcibly stepped to enable the middle shoe to abut against and push the arc block to retract into the notch, and the brake drum is driven to rotate. The middle shoe is further in contact with the inner wall of the brake drum when making contact with the arc blocks, the side shoes are completely in contact with the inner wall of the brake drum, the whole shoe module works and is used for braking of the brake drum, segmented use of the braking function is achieved, speed reduction and braking after speed reduction can be conducted in the high-speed state, abrasion to the shoe module is effectively reduced, and the service life of the brake drum is prolonged. The service life of the brake shoe is prolonged, and the use cost is reduced.

    本发明公开了一种可调节式刹车总成,包括车轴杆以及设置有刹车蹄的轴壳,还包括转动设置的刹车鼓,所述刹车鼓内壁圆周布置有缺口,且所述缺口中活动设置有弧块。本发明提供的可调节式刹车总成,通过轻踩脚踏来使中蹄片主动贴近旋转状态下的弧块,并产生滑动摩擦来用作刹车鼓降速,而当降速后需要再度减速或刹停时,用力踩压脚踏来使中蹄片抵推弧块缩回缺口,使中蹄片接触弧块时还接触刹车鼓内壁,而边蹄片则完全接触刹车鼓内壁,使整个蹄片模组均工作并用作刹车鼓的制动,实现刹车功能的分段使用,可在高速状态下进行降速以及减速后的制动,有效降低对蹄片模组的磨损,提高刹车蹄片的使用周期,降低使用成本。
