Abstract
The utility model belongs to a shaft join type transmission speed-changing mechanism using bevel gear wheel, which is arranged between a central shaft and a rear wheel hub of a bicycle or a motorcycle which is limited in structure and space. The utility model can realizes the functions of steady and labor-saving transmission, multi-change speed, etc. The structure is characterized in that the transmission shaft is connected with the central shaft and the rear wheel hub through a bevel gear transmission auxiliary, and the speed-changing mechanism is mainly composed of cone gear sets. The utility model has the advantages of compact structure, reasonable transmission, reliable speed-changing, portability, durability, etc., and is particularly suitable to be used in the transmission speed-changing mechanism between the central shaft and the rear wheel hub of two-wheel bicycle.
Description
The utility model relates to a kind of at the axis of bicycle that is subject to certain restrictions on structure and the space or motor bike and the axle connection formula Bevel Gear Drive speed-changing mechanism between the rear-wheel hub, and it comprises basic structures such as Bevel Gear Drive pair, transmission shaft, supporting structure, speed-changing mechanism and ratchet device.
Existing bicycle or motor bike are to adopt sprocket wheel, chain drive mostly, and its shortcoming is that transmission is not steady, impact is strong and serious wear and speed change complexity and difficulty etc.In order to solve the chain-drive shortcoming, disclosing a kind of application number in the Chinese patent gazette on August 5th, 1987 is 86207970 " transmission shaft type speed change Manpower driver ".Its formation is: " that axis (dynamical axis) is gone up is fixing (have two roads with upper ring gear) active plane gear and to be fixed between the driven face gear on the wheel hub be by a propeller shaft couplings; the one end is a spline; on be equipped with and active plane gear slippage cylindrical wheel that be meshed and that have shift fork; its other end is equipped with the fixed cylinder gear that is meshed with driven face gear, and the two ends of transmission shaft are supported by bearing ".Weak point is because the theory of engagement that cylindrical wheel and the engagement of flat circle tooth bar are not accordant to the old routine must bring " driving and driven face gear " processing difficulties to contact caused a series of problem with engagement for point.
The purpose of this utility model is to overcome and avoids above-mentioned shortcoming and defect part of the prior art and a kind of Bevel Gear Drive speed-changing mechanism is provided.
The purpose of this utility model can realize by following structure:
The Bevel Gear Drive speed-changing mechanism comprises structures such as Bevel Gear Drive pair; Transmission shaft; Supporting structure; Speed-changing mechanism and ratchet device and adjusting; location, operation.The axis ( dynamical axis ) that the vehicle frame mesopore promptly assembles in the through hole of six connection for bbreather pipes and rear axle ( drive sprocket axle ) go up between the rear-wheel hub of assembling be passed through to be installed in vehicle frame siamesed distortion breeches pipe in the propeller shaft couplings that supports by bearing.The utility model difference with the prior art is characterised in that between transmission shaft and axis and the rear-wheel hub ( also can be front wheel hub ) it is to be connected by Bevel Gear Drive is secondary.。 Special feature of the present utility model is that also described Bevel Gear Drive speed-changing mechanism not only can be provided with ratchet device as prior art between rear axle and rear-wheel hub, but also can transmission shaft rear end assembling and rear-wheel hub on fixing driven bevel gear ingear transmission conical gear and transmission shaft radially between internal-gear type ratchet device or friction-type ratchet device (claiming overriding clutch again) are set.
Accompanying drawing is that the utility model specific embodiment two wheel bicycle structures are analysed and observe the assembling scheme drawing.
The utility model is described in further detail below in conjunction with the accompanying drawing illustrated embodiment:
Axis six connects pipe 15 and forms the present embodiment matrix with breeches pipe 6 with by distortion breeches pipe head 7, breeches pipe adapter 26, back supporting mass 5 and lintel bent plate 35 by the welding or the distortion breeches pipe that constitutes that is threaded.Take over assemble in 26 the through hole be installed with wheel disc 19 by bearing 14,16 supportings and by the outer end of the axis 20 that roller bearing end cap 17 is adjusted, sealing cap 18 is fastening.Fixed installation rear axle 36 between breeches pipe 6 rear ends and the lintel bent plate 35.In distortion the transmission shaft that castellated shaft 8 that is welded respectively by cardan shaft housing 27 two ends and ratchet shaft 28 by thrust bearing 4,21 supportings entad form is housed in the breeches pipe.Speed cone gear 13, its external diameter assembling of having the male splines platform on the thin optical axis of castellated shaft 8 front ends of transmission shaft front end on aft end face of assembling have the female splines slippage spline housing 10 that can cooperate with castellated shaft 8 and speed cone gear 13 male splines platforms.Two of the external diameter of spline housing 10 assemblings by locations 12 axial limitings, have female splines can with the speed cone gear 11,9 of the short spline fitted of external diameter of spline housing 10.The rear end external diameter of spline housing 10 is provided with gear shift fork 25.Speed cone gear 13,11,9 respectively with wheel disc 19 on active conical gear circle 22,23,24 engagement of processing.The anterior external diameter of the ratchet shaft 2,28 of transmission shaft rear end is that the bearing gland 3 with back supporting mass 5 screw-internal thread fit is equipped with in the rear end of bearing 4.Gland 3 rear ends are equipped with and overriding clutch 31 are set between its internal diameter and the ratchet shaft 28 and adjust fastening transmission conical gear 30 by ball 29 supportings and rear side housing 32, packing ring 33 and nut 34.Fixed installation of the outer end of the rear-wheel hub 2 of assembling and transmission conical gear 30 ingear driven bevel gears 1 on rear axle 36.
The utility model has compact conformation compared to existing technology, transmission is reasonable and speed change reliably reaches the advantages such as Portable durable, can be widely used in the transmission mechanism of the bicycle that is subject to certain restrictions in structure and space or motorcycle, be particularly useful in the axis and the transmission shifting mechanism between the rear-wheel hub of two-wheeled cycle.
Claims (1)
1, the Bevel Gear Drive speed-changing mechanism, comprise the Bevel Gear Drive pair, transmission shaft, supporting structure, speed-changing mechanism and ratchet device, be to be connected between transmission shaft and axis 20 and the rear-wheel hub 2 by Bevel Gear Drive is secondary, of the present utility model be characterised in that speed-changing mechanism be by the active conical gear dish 19 inner faces fixed installation that is fixed on axis 20 outer ends or process respectively more than two with the conical gear circle 22 of vertex of a cone different cone angle and reference diameter, 23,24 and empty be enclosed within the transmission shaft front end respectively with conical gear circle 22,23,24 ingear speed cone gears 13,11,19 and transmission shaft and speed cone gear between slide key cover 10 form.
