摘要:
An elastic wheel comprising a disk (1) secured to an axle hub, and a rim (12) supporting a tire, wherein an elastic member (10) is interposed between the inner peripheral surface of the rim (12) and the outer peripheral surface of the disk (1). An attachable/detachable construction is employed between the outer peripheral surface (2) of the disk (1) and a wheel radial disk (3) or between the inner peripheral surface of the rim (12) and the elastic member (10) or in both cases. This ensures the permanence of riding comfort performance specific to an elastic wheel, vibration proof performance, and sound proof performance, and makes it possible to optimize such performances according to use even during use. Further, the mounting of a rim set and a core is facilitated and when rubber is used for the elastic member, rim-integrated vulcanization becomes unnecessary, thus making size reduction of the vulcanizing device possible.

The sleeve 127, 227, 327, 427 includes an axle stabilizing recess 198, 298, 398, 498 positioned in an end wall 158, 258, 358, 458, which receives an axle stub 199, 299 that supports the axle 123, 223 against lateral loading and stabilizes it to reduce wobble, chatter and vibration.
摘要:
A plastic wheel assembly (122, 222) and wheel mounting sleeve (127, 227) used to releasably secure the wheel (122, 222) onto an axle (123, 223). The wheel mounting sleeve (127, 227) includes an axle stabilizing opening (100, 200) positioned in an end wall (158, 258) of the sleeve which receives an axle outer end or axle stub (199, 299) that supports the axle (123, 223) against lateral loading and stabilizes it to reduce wobble, chatter and vibration. The opening (100, 200) permits visual confirmation of proper section of the axle outer end (199, 299) in the opening (100, 200). A universal axle (223, 223a) is also provided which can be used to couple wheels (122, 222) having shaped axle bores (139, 239) to the axle using wheel mounting sleeves (127, 227), as well as being used to couple wheels (420), having straight or substantially cylindrical bores (439), to the axle using conventional fasteners (450, 461, 470).

摘要:
A plastic wheel (22, 122) and wheel mounting sleeve (27, 27a, 127) used to releasably secure the wheel (22, 122) onto an axle (23, 123). The wheel mounting sleeve (27, 27a, 127) preferably includes a resilient, radially displaceable, axially extending, cantilevered finger (46, 146) which includes an axle-engaging lug (55, 155), while a wheel-engaging shoulder is provided on an annular rib 101, 201. The respective sleeve shoulders cooperate with oppositely facing shoulders on the wheel so as to latch the sleeve (27, 127) to the axle (23, 123) and the wheel (22, 122) to the sleeve (27, 127). The sleeve (27, 127) and sleeve-receiving bore (39a, 39b, 139a, 139b) are radially inwardly stepped on the inner side (66, 166) as compared to the outer side (67, 167) if wheel. Assembly can be accomplished without any tools, and a pointed tool can be used to puncture a skin (195) in a passageway (191) so as to enable release of the sleeve (27, 127) and wheel (22, 122) from the axle (23, 123).

Das Fahrzeugrad besteht aus einem Radstern (2) und einer Felge (3), die miteinander durch eine Schweißung verbindbar sind. Hierzu sind am Radstern sowie an der Felge miteinander korrespondierende Verbindungsflächen (9-19) vorgesehen, welche unterschiedlich schräg oder gleich schräg angestellt sind, damit eine Zentrierung der beiden Radteile zur Schweißung miteinander bewirkt wird.
摘要:
An elastic wheel includes a disk (1) secured to an axle hub, a rim (12) for mounting a tire, and an elastic member (10) arranged between the inner peripheral surface of the rim (12) and the outer peripheral surface of the disk (1). The elastic wheel is separable either between an outer peripheral surface portion (2) and a radial disk portion (3) of the disk (1), or between the inner peripheral surface of the rim (12) and the elastic member (10), or at both locations. This construction ensures long-lasting passenger comfort, anti-vibration performance and noise-suppression performance of the elastic wheel and allows optimization of these characteristics depending on applications of the wheel even during its use. The elastic wheel facilitates rim assembly as well as core mounting. Also, in cases where rubber is used to serve as the elastic member in the elastic wheel, vulcanization can be carried out without using an integrated rim unit, thereby making it possible to reduce the size of vulcanization apparatus.
