由卡斯-4540牵引车和梯克勃-8335挂车组成的农用汽车列车,具有楔形张开制动蹄的鼓式制动器。该种制动机构比凸轮式鼓式制动机构轻15～20%。它是一种具有分开式外形的结构简单的制动系,并能自动调节制动蹄与制动鼓之间的间隙。新式机构还减少了压缩空气的消耗。
An agricultural vehicle train consisting of a Castrol-4540 tractor and a ladder-8335 trailer with a drum brake with a wedge-shaped brake shoe. This kind of brake mechanism is 15 to 20% lighter than the cam drum brake mechanism. It is a simple-structured braking system with a separate profile and automatically adjusts the clearance between the brake shoes and the brake drum. The new mechanism also reduces the consumption of compressed air.
