연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

Disclosed and taught is a novel drive mechanism for a cyclic operating tool employing an energized flywheel to provide the necessary energy to perform a working cycle. The drive mechanism disclosed is particularly useful in hand tool applications such as a hand held nailing machine. The flywheel may be energized by a corded or battery powered motor. The herein disclosed mechanism teaches a novel pair of ball ramp cam plates wherein a first pair of ball ramps cause an initial engagement of a clutch with the energized flywheel whereupon rotation of the clutch causes activation of a second pair of ball ramps which affect compression of a spring which acts to increase the pressure applied to the clutch thereby assuring a slip free engagement between the clutch and he flywheel throughout the working cycle of the drive mechanism. Upon completion of the drive mechanisms working cycle, the second pair of ball ramp cam plates further act to disengage the clutch from the flywheel whereby the flywheel may dissipate the unused kinetic energy remaining within the flywheel as the drive mechanism returns to the start position. bearing bracket being arranged in a side joint of the rear hatch in the vehicle body and connected to a post of the vehicle body by way of a holding angle; and wherein the boreholes run on a rear-sided exterior of the post. 3. Holding device as claimed in claim 2, wherein the hinge bolt of the top bearing comprises a joint element which comprises a spherical segment on the bolt which is held in the corresponding bearing shells of the bearing bracket. 4. Holding device for a spare wheel of a motor vehicle, said holding device being disposed on the outside of a swivellable rear hatch and comprising a wheel carrier which is held by at least two support arms and which is supported by way of bearings on the vehicle body so as to swivel, the support arms being spaced apart and projecting from the wheel carrier and end sides thereof being connected to the bearings, the bearings being held on the vehicle body and forming a vertical swivel axis which is arranged independently of a swivel axis of the rear hatch, the wheel carrier being swivellable about the swivel axis of the bearings up to the rear hatch into a fixing position and being held on a shock absorber cross member by way of a support member in a holding element and being freely swivellable from the rear hatch into a release position, wherein a holding angle is attached with its one attachment leg for the bearing bracket to an inside wall surface of a post of the vehicle body and with its other holding leg to an outside wall surface of the post. 5. Holding device for a spare wheel of a motor vehicle, said holding device being disposed on the outside of a swivellable rear hatch and comprising a wheel carrier which is held by at least two support arms and which is supported by way of bearings on the vehicle body so as to swivel, the support arms being spaced apart and projecting from the wheel carrier and end sides thereof being connected to the bearings, the bearings being held on the vehicle body and forming a vertical swivel axis which is arranged independently of a swivel axis of the rear hatch, the wheel carrier being swivellable about the swivel axis of the bearings up to the rear hatch into a fixing position and being held on a shock absorber cross member by way of a support member in a holding element and being freely swivellable from the rear hatch into a release position, wherein the bearing bracket comprises a projecting arm which corresponds to an attachment leg of a holding angle and to which is attached a bearing segment having a U-shaped cross section and which comprises vertically spaced bearing plates having bolt boreholes, said bearing segment having a rear side which rests true to shape against an outer wall surface of a post of the vehicle body. 6. Holding device for a spare wheel of a motor vehicle, said holding device being disposed on the outside of a swivellable rear hatch and comprising a wheel carrier which is held by at least two support arms and which is supported by way of bearings on the vehicle body so as to swivel, the support arms being spaced apart and projecting from the wheel carrier and end sides thereof being connected to the bearings, the bearings being held on the vehicle body and forming a vertical swivel axis which is arranged independently of a swivel axis of the rear hatch, the wheel carrier being swivellable about the swivel axis of the bearings up to the rear hatch into a fixing position and being held on a shock absorber cross member by way of a support member in a holding element and being freely swivellable from the rear hatch into a release position, wherein a body post exhibits an insertion opening for internal arrangement of an attachment leg of a holding angle. 7. Holding device for a spare wheel of a motor vehicle, said holding device being disposed on the outside of a swivellable rear hatch and comprising a wheel carrier which is held by at least two support arms and which is supported by way of bearings on the vehicle body so as to swivel, the support arms being spaced apart and projecting from the wheel carrier and end sides thereof being connected to the bearings, the bearings being held on the vehicle body and forming a vertical swivel axis which is arranged independently of a swivel axis of the rear hatch, the wheel carrier being swivellable about the swivel axis of the bearings up to the rear hatch into a fixing position and being held on a shock absorber cross member by way of a support member in a holding element and being freely swivellable from the rear hatch into a release position, wherein a bearing bracket is enveloped by a cover element which is slidable thereon and which comprises an opening for one of the support arms and whose rear sided face rests sealingly on a wall surface of a post of the vehicle body. 8.
