A study on properties of a cone-type brake for motor vehicle winch

Abstract

The brake of winch is to prevent the occurrence of reverse slipping at working time. Based on the analysis of two types of brake, this article establishes the relationship model of the brake force and the angle of the screw thread on the brake shaft and builds the model of the relationship of the brake force and the height of the cone and found that the brake force is the largest when the angle of the screw is 45°. Also found that the brake force increases with the increase in the load, and the brake force is positively related to the height of the cone. Two brake mechanisms are manufactured and arranged in the same winch to conduct the experimental performance comparison. The experimental results show that the temperature of the winch with cone brake finally reaches about 60°C, which is 33% lower than the 90°C of the disk brake, and the no-load current of the cone brake winch is under 60 A, while in the disk brake winch it is over 90 A after 7 min, which consumes 33% energy than cone brake. The cone brake can reduce the occurrence of harmful friction and enhance the efficiency of winch and is able to solve the winch safety problem caused by nylon cable damage because of the heat accumulation.

Application of the Taguchi method to determine optimized parameters for designing brake of hand winch

“…The study in [10] introduces the structural composition and working principle of the cone brake, analyzes the advantages of the cone brake, through comparison with the drum brake, gives optimization suggestions for the shortcomings existing, and explores application prospects of new brakes. Research in [11] has shown that the cone brake can reduce the occurrence of harmful friction improve the efficiency of the winch, and can solve the winch safety problem caused by temperature build-up. The study in [11] also established a model of the brake force Engineering relationship and the angle of inclination of the screw thread on the brake shaft.…”
