Embodiment Construction

[0018] An embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0019] The vehicle winch automatic brake device of the present invention mainly consists of a shaft cover 1, a brake shaft 2, a circlip 3 for the shaft, a lug plate 4, a torsion spring 5, a cone brake part 6, a brake cone sleeve 7, a single-row conical roller The sub-bearing 8 is composed of the brake taper sleeve 7 and the spline engagement of the outer cable disc. The brake shaft 2, the lug disc 4, the torsion spring 5, and the cone brake parts 6 form a screw clutch mechanism, and the brake shaft 2 drives the screw clutch mechanism. The clutch mechanism realizes separation. One end of the brake shaft 2 extends into the shaft cover 1, and the brake shaft 2 extends into the screw clutch mechanism provided on one end of the shaft cover 1. The screw clutch mechanism includes a cone brake part 6, a torsion spring 5 and lugs. The disc 4 and the cone brake part...

Abstract

The invention discloses an automatic brake device and an automatic brake method of an automobile capstan. The device comprises a shaft cover, a brake shaft and a spiral clutch mechanism, wherein the spiral clutch mechanism comprises a cone brake part, a torsion spring and a convex lug plate; the brake shaft is provided with a single-row tapered roller bearing; the single-row tapered roller bearing is provided with a brake cone sleeve jointed with the cone brake part; the outer edge of the bake cone sleeve is provided with a spline which is meshed with an inner gear ring of a capstan winding drum. When a motor driving shaft rotates, the shaft cover makes clockwise rotation, the cone brake part is driven to rotate, and the torsion spring is extruded to move towards the left, so that the cone brake part is separated from the brake cone sleeve; when the motor driving shaft stops rotating, the cone brake part makes counterclockwise rotation to reset under the action of the torsion spring, the cone brake part move towards the right and is jointed and tightly held with the brake cone sleeve which runs at low speed, and the brake shaft stops rotating, so that the function of braking is reached. The device is simpler in structure, easy to operate, rapid in assembly, high in brake reliability, low in working temperature and long in service life.

Description

technical field [0001] The invention relates to an automatic braking device and method, in particular to a vehicle winch automatic braking device and method suitable for various automobiles and yachts. Background technique [0002] The car winch is mainly used for agricultural vehicles, off-road vehicles, yachts, ATV sports vehicles and other special vehicles. It is a device for self-protection and traction of vehicles and ships. It can carry out vehicle self-rescue in harsh environments such as snow, swamps, deserts, beaches, and muddy mountain roads, and may perform operations such as clearing obstacles, dragging objects, and installing facilities under other conditions. It is an indispensable safety device for forestry, transportation, public security, frontier defense, fire protection and other outdoor sports. The key to ensure the safe operation of the winch when the winch brakes, so the winch brake must be reliable. [0003] The patent application number is CN2009201...
