Clutch mechanism having cushioning function

Abstract

The invention discloses a clutch mechanism with buffer. It contains a fist spindle, a secondary spindle and a clutch sleeve with location meshing which can move along radial on axostyle of the secondary spindle. Set a meshing face on end of the first spindle and a gear rack on front section of the secondary spindle. The clutch sleeve is coupled by a clutch collar controlled by a shifter which can move along radial and a buffer mechanism is set between them. The buffer mechanism contains a spring sleeve, a buffer ring and a spring between them. The invention has simple structure, low cost, small capacity and easy equipment, which can effectively avoid damages on driving module caused by dislocation of active gear and passive gear and guarantee safe and long useful life of machine.

Description

technical field [0001] The invention relates to a clutch mechanism with a buffer function that can be widely used in shaft transmission. Background technique [0002] Generally, the design of the clutch mechanism for the shaft transmission of the vehicle is known, such as: US Patent No. 5,997,428 related to the power switching clutch design of the two-wheel transmission and the four-wheel transmission. [0003] The previous technical literature discloses a clutch design mechanism for power transmission between two rotating shafts, which uses a shift fork sleeve disposed between opposite ends of the two rotating shafts to generate a clutch for power transmission between the two rotating shafts. [0004] In these designs, when the displacement of the shifting fork sleeve bridges the two rotating shafts to generate a power transmission connection, the displacement of the shifting fork sleeve on one rotating shaft intends to engage and the other rotating shaft is instantly meshe...

Problems solved by technology

[0004] In these designs, when the displacement of the shifting fork sleeve bridges the two rotating shafts to generate a power transmission connection, the displacement of the shifting fork sleeve on one rotating shaft intends to engage and the other rotating shaft is instantly meshed and misaligned. Due to the design technology and space type factors, the components are complicated and occupy space, so the external space of the machine tool is used to set up the relevant buffer mechanism separately. Not only the structure is complex, the volume is large, the cost is high, but also the assembly process is time-consuming and labor-intensive. , does not meet the utilization of industrial demands and the efficiency of economic demands
