Definitions

  • the present Invention relates to a starting device for engines comprising a one-way clutch that allows driving force to be transmitted only from a starter to an engine.
  • starters include an electromagnetic push-in type starter, which allows a pinion gear to be engaged with a ring gear in an engine side using electromagnetic force of an electromagnetic switch (electromagnet), and causes driving torque of a motor to be transmitted to the ring gear via the pinion gear to start an engine.
  • the electromagnetic push-in type starter comprises a one-way clutch so that the rotation of the engine is not transmitted to an armature of the motor. Once a rotation speed of the engine at a complete combustion state by cranking exceeds a rotation speed of the starter, the one-way clutch runs idle and cuts off the rotation torque from the engine, so as to prevent the motor armature of the starter from overrunning.
  • a control system for automatically stopping and restarting an engine is also known (this system is called an idle-stop system).
  • This system requires the engine to be restarted with much less time (for example, within 0.4 seconds) than the typical engine starting system which uses a key switch, after the engine automatically stops.
  • the electromagnetic push-in starter one of the devices for starting the engine, requires time for the pinion gear to be pushed out and engaged with the ring gear, which requires extra time to start the engine. Further, this starter generates noise when the pinion gear and the ring gear are engaged with each other.
  • a starter device comprises a driving gear engaged with a pinion gear of a starter at all times, and that the reduction gear is connected to a crank shaft of an engine via a one-way clutch (see, for example, Japanese Patent Application Laid-Open Publication No. 2000-274337 and German Patent Application Laid-Open Publication No. 10343400 ).
  • this starter device the pinion gear and the driving gear are engaged with each other at all times, so that they do not have to be engaged when the engine is started. Therefore, this device can start the engine more quickly with less time than the electromagnetic push-in starter. Further, this starter device does not produce noise when the gears are engaged, which allows the engine to start noiselessly.
  • the conventional starting device for engines having the one-way clutch in the ring gear has to include a sealing construction between a clutch outer connected to and rotated with an engine and a clutch inner connected to the ring gear so as not to be rotated after the engine starts running, in order to prevent lubricating grease from leaking outside, and to prevent ambient water and the like from entering inside.
  • a seal member is disposed on an outer circumference of the clutch outer, such a structure can cause the seal member to be large in diameter, and cause the circumference velocity of the seal lip of the seal member to become significantly great, resulting in increased friction loss and decreased durability of the seal member.
  • the increased friction loss can increase the load of the engine being run, and worsen the fuel consumption of the engine.
  • this construction has to Include a seal retainer inside the ring gear, and the seal retainer as well as the outer circumference of the clutch outer has to be finished with a high degree of accuracy in order to provide sufficient sealing properties.
  • this construction requires a large sealing space, which causes extra lubricating grease to be filled in an area other than the area the clutch is disposed where the lubricating grease has to be filled. This can cause economic loss.
  • JP 2007 132311 A discloses a stator of internal combustion engine which includes a one-way clutch which is lubricated by surplus fuel discharged from a fuel injunction valve.
  • WO 2007/012943 A1 discloses a startup torque mechanism of an internal combustion engine which includes a one-way clutch which requires no supply of lubrication oil.
  • the present invention has been made in order to solve the issue described above, and has as its object to provide a starting device for engines that allows a seal member used in the device to be smaller in its diameter and to have an improved durability.
  • a starting device for engines according to the invention for solving the above-mentioned problems will be described below with advantages thereof.
  • a starting device for engines comprises a first rotor having a gear engaged with a pinion gear of a starter at all times; a second rotor connected to a crank shaft of an engine; and a one-way clutch for transmitting driving force from only the starter to the engine.
  • the one-way clutch comprises a clutch inner integrally or independently formed with the first rotor and fixed to the first rotor; a clutch outer disposed on an outer circumference side of the clutch inner and fixed to the second rotor; and a clutch-engaging member disposed in a space formed between the clutch inner and the clutch outer.
  • the starting device for engines further comprises a seal member disposed between the clutch engaging member and the first rotor, and between the clutch outer and the clutch inner.
  • the seal member comprises an outer circumference side contacting an inner circumference of the clutch outer and an inner circumference side contacting an outer circumference of the clutch inner. Either the outer circumference side or the inner circumference side is fixed, while the other side is left free and provided with a lip portion.
  • the clutch outer has a smaller diameter portion contacting the seal member, and a larger diameter portion at which the clutch engaging member is disposed.
  • the starting device for engines comprises the seal member between the clutch engaging member and the first rotor and between the clutch outer and the clutch inner, wherein the seal member comprises an outer circumference side contacting an inner circumference of the clutch outer and an inner circumference side contacting an outer circumference of the clutch inner, in which either the outer circumference side or the inner circumference side is fixed, while the other side is left free and provided with a lip. Accordingly, the starting device for engines can prevent lubricating grease, which is filled in a space where the clutch engaging member is disposed, from leaking outside, and also prevent ambient water or the like from entering inside the device.
  • the device can allow the seal member to be more compact in diameter than another type of seal member that is disposed on the outer circumference of the clutch outer. This can reduce the circumference velocity and friction loss of the lip portion of the seal member, and increase durability of the lip portion. Moreover, the device allows the space for the seal member in the one-way clutch to be small, which can reduce the amount of lubricating grease to be used. Also, the device does not require the outer circumference of the outer clutch to be finished with a high degree of accuracy, which allows the cost of production to be lowered.
  • the outer circumference of the seal member contacting the inner circumference of the clutch outer is fixed, while the Inner circumference contacting the outer circumference of the clutch inner is left free and provided with a lip portion.
  • the inner circumference of the seal member contacting the outer circumference of the clutch inner is fixed, while the outer circumference contacting the inner circumference of the clutch outer is left free and provided with the lip portion.
  • the seal member has the first end contacting the inner circumference of the clutch outer and the second end contacting the outer circumference of the clutch inner, wherein the first end is fixed and the second end is left free and provided with a lip portion.
