Improved winch brake device and installation method thereof

Abstract

The invention relates to an improved winch brake device and an installation method thereof. The improved winch brake device comprises a drive seat, a torsion spring, a brake fork, a positioning ring, and a brake sleeve; the design key points are that two ends of the torsion spring are provided with a torsion spring upper seat and a torsion spring lower seat; the circumferential surface of one end of the drive seat is provided with a fan-shaped flange, and the other end of the drive seat is provided with a limit notch; one end of the torsion spring upper seat is provided with an annular groove; a limit block is arranged in the annular groove, and the other end of the torsion spring upper seat is provided with an upper seat fan-shaped sliding block, and an upper seat hook groove into which a hook of the torsion spring is inserted; one end of the torsion spring lower seat is provided with a limit lug; the circumferential surface of the torsion spring lower seat is provided with a lower seat fan-shaped sliding block which is provided with a lower seat hook groove into which a hook of the torsion spring is inserted; one end of the drive seat, which is provided with the limit notch, penetrates through the torsion spring upper seat, and is rotatably matched with the limit lug of the torsion spring lower seat in a limited way; and the upper seat fan-shaped sliding block and the lower seat fan-shaped sliding block are independent of each other and are rotatably matched with a fan-shaped lug of the brake fork in a limited way. The improved winch brake device is high in brake stability and reliability, long in service life and is suitable to be used as a winch brake device or structural improvement of similar products.

Description

technical field [0001] The invention relates to a winch auxiliary device, which is an improved winch braking device and an installation method thereof. Background technique [0002] The winch is an auxiliary equipment used in automobiles, mainly used for self-rescue or as a traction device. In order to ensure the safety of the winch during use, the general winch has the function of automatic braking, that is, when the winch stops, the traction rope of the winch can be automatically locked to prevent the problem of traction failure. In the prior art, such as the authorized announcement number CN201873483U published in the Chinese patent literature, the authorized announcement date was June 22, 2011, and the name of the utility model is "winch automatic braking device", which mainly includes brake seats, brake forks, brake Spring, brake sleeve, positioning ring, the middle part of one end of the brake seat is a cylinder, and the side of the cylinder is integrated with a fan-s...
