Embodiment Construction
[0029] Such as Figure 1 to Figure 7 As shown, the winch shift clutch of the present invention includes a housing 1 and a handle 2. The housing 1 is provided with a clutch camshaft 3, and the clutch camshaft 3 is connected with a shift camshaft 4 and a shift clutch shaft. 5. The cam surfaces on the clutch camshaft 3 and shift camshaft 4 are sequentially linked and fitted. The clutch camshaft 3 is provided with a cam curved surface I32, the shift camshaft 4 is provided with a cam curved surface II42, and the shift camshaft 4 is also provided with an annular curved surface 43 connected with the cam curved surface II42. The position of the cam curved surface I32 is corresponding, and the cam curved surface I32, the cam curved surface II42 and the torus curved surface 43 are all 1 / 4 circular arcs. A clutch return spring 31 is provided between the clutch cam gear shaft 3 and the housing 1, and the clutch cam gear shaft 3 is provided with an annular slot 33. One end of the clutch r...

Abstract
The invention discloses a winch gear-shift clutch, which comprises a shell and a handle, wherein the shell is internally provided with a clutch cam gear shaft; a gear-shift cam shaft and a gear-shift clutch shaft are inserted into the clutch cam gear shaft; the cam curve surfaces on the clutch cam gear shaft and the gear-shift cam shaft are linked to fit in sequence; and a clutch reset spring is arranged between the clutch cam gear shaft and the shell, a gear-shift reset spring is arranged between the gear-shift cam shaft and the shell, the gear-shift clutch shaft is provided with a positioning component sliding on the cam curve surfaces, and the handle is fixedly connected with the gear-shift clutch shaft. The winch gear-shift clutch has the advantages of simple operation and reliable operation, and increases a double-speed function under the conditions that the winch function is not reduced and the ratio of the weight to the pull force of the winch is not reduced. Clutching and gear shifting are integrated, namely gear shifting and clutching share one operating handle; two actions generated by the gear-shift and clutch components are organically combined with the speed reducer; and the winch speed reducer gear automatically carries out separation and mesh. The winch gear-shift clutch has the advantages of convenient and reliable operation, compact structure, low fault rate and long service life.
Description
technical field [0001] The invention relates to a shifting clutch for a winch. Background technique [0002] There are many types of winches, including all kinds of recreational off-road vehicle marine winches, various special engineering winches, various military special-purpose winches and other special winches for various industries, etc., which are widely used in leisure off-road, engineering rescue, metallurgy, exploration, forestry, animal husbandry, fishery and Petroleum, mineral mining, etc., among which leisure off-road is the main market of winches. At present, domestic and foreign winches are usually composed of motors (electric motors, hydraulic motors, pneumatic motors, etc.), drum brakes, reducers, clutches, controllers, wire ropes and some corresponding accessories, which can basically meet the requirements of various working conditions. However, it cannot adapt to the higher and higher living standards and technical requirements of working conditions. More a...
