Embodiment Construction

[0021] Below in conjunction with accompanying drawing, structural principle and working principle of the present invention are specifically described:

[0022] see figure 1 , Figure 2A-Figure 2D Shown, the present invention is a kind of overrunning clutch with delay function, is used for linking a driving gear 10 and a crankshaft 20, and it comprises a first collar 30, a second collar 40, a roller cage 50 and At least one control ring 60. Wherein the first collar 30 is connected with the starter gear 10, the second collar 40 is connected with the crankshaft 20, and the first collar 30 and the second collar 40 can rotate relatively coaxially. 40 has a plurality of recesses 41 each with an inclined bottom surface 42, and the first collar 30 is sleeved on the outside of the second collar 40, and the first collar 30 and the second collar 40 can be At least one set of roller bearings 70 is provided to increase the stability of rotation.

[0023] The roller cage 50 is disposed ...

Abstract

An overrunning clutch with delay function, comprising a first collar connected to a driving gear, a second collar connected to a crankshaft, a roller cage and at least one control ring, the first collar and The second collar fits and can rotate relative to the same axis. The second collar has a plurality of recesses with an inclined bottom surface. There is a first friction force between the second collar and the roller cage. touch. The roller cage has a recessed annular region and has rollers corresponding to the pockets of the second collar. The first collar has at least one annular groove correspondingly accommodating the plurality of control rings, and the first collar and the plurality of control rings are in close contact with each other with a second friction force. The plurality of control rings also have a hook structure correspondingly accommodated in the recessed area of ​​the ring surface of the roller cage, which can delay the engagement of the overrunning clutch and avoid damage caused by the shock load generated when the internal combustion engine is turned off and the crankshaft is reversed. .

Description

technical field [0001] The invention relates to an overrunning clutch, in particular to an overrunning clutch with delay function. Background technique [0002] A kind of internal combustion engine starting system widely used at present, it arranges an overrunning clutch between the starting gear and the crankshaft, when the speed of the starting gear is higher than the crankshaft speed, the overrunning clutch is in the meshing state; At crankshaft speed, the overrunning clutch is not engaged. [0003] Therefore, at the initial stage of starting the internal combustion engine, the power output by the starter motor drives the crankshaft through the starter gear and the overrunning clutch (or called a one-way clutch) to rotate the internal combustion engine. And after internal-combustion engine starts, the rotational speed of crankshaft can be higher than the rotational speed of starter gear, and this moment, overrunning clutch promptly becomes non-engagement state, and the p...
