Abstract
The invention discloses a ball type engaging and disengaging mechanism. The mechanism comprises a suite, a starter driving gear, a sector-shaped block, balls, buffering assemblies, a shifting fork sliding ring and a spline sliding sleeve. The smooth portion at the front end of the spline sliding sleeve is sleeved with the starter driving gear. A protruding structure is arranged at the rear end of the starter driving gear. Ball grooves are formed in the two side faces of the protruding structure. The buffering assemblies are arranged on the portions, corresponding to the ball grooves, of the spline sliding sleeve, the ball is arranged at one end of each buffering assembly, and the ball is arranged in the corresponding ball groove in a sleeved mode. By means of relative supporting force of the buffering assemblies and the balls on the ball grooves, the torque of the starter driving gear relative to a main shaft is controlled. When the torque is increased, the supporting strength is smaller than the torque strength, accordingly the balls are disengaged from the ball grooves, and the danger that a starter overspeeds is prevented. Besides, the mechanism can support large torque, sensitivity is high, axial size is small, the structure is simple, and cost is low.
Description
Technical field
The present invention relates to clutch mechanism technical field, be specially a kind of ball type clutch mechanism.
Background technique
The effect of clutch mechanism: during engine start, makes the kinetic force of motor pass to bent axle by gear; After engine start, cut off power transmission line immediately, avoid motor to drive high engine speeds to rotate by flywheel, at present, conventional Starter clutch mechanism has roller type, friction disk type and spring three kinds.
Wherein, roller type clutch mechanism is by the inner race of outer ring support, breach, roller and be communicated with the plunger that spring is contained in inner race bore together and form, and the splined sleeve of inner race and starter shaft are with spline joint, and the gap width between outer race and inner race is not etc.When starter motor rotates, torque passes to inner race by splined sleeve, inner race then rotates with axle, at this moment roller just can roll in breach stuck, so starter driving gear is passed in torque, flywheel driven makes engine start, when after engine start, speed of crankshaft increases, and flywheel ring gear drives actuation gear to rotate, now, drive sense of rotation not change, but become driven gear from driving gear, and outer race, so make roller roll into the wide place of breach, inner and outer race is skidded relatively.Such torque just can not pass to main shaft from starter driving gear, thus prevents the danger of mainshaft overdrive, but this roller type clutch mechanism is easily stuck when transmitting larger torque.
In rising, friction disk type clutch mechanism can transmit larger torque, but not high in the structure medium sensitivity of High Rotation Speed; The Structure and energy of spring clutch mechanism is simple, and cost is low, but the number of turns of required brake spring is more, causes axial dimension long.
