Abstract
The utility model relates to a V-belt pulley variable speed device for a motorcycle. The utility model is characterized in that the end of a crankshaft (1) is provided with a driving gear (6), the longitudinal position of a vehicle body forming a right angle with the crankshaft (1) and the crankshaft (1) are provided with a variable speed device main shaft (8) in parallel, wherein, the middle part of which is provided with a main belt pulley (2) and the end of which is provided with a driven gear (7), and the driving gear (6) drives the driven gear (7) to make the main belt pulley (2), a V type belt (3) and the driven pulley (4) to run so that the stepless variable speed is carried out. The V-belt pulley variable speed device has narrow transverse dimension and symmetrical weight, particularly having beautiful appearance, good damping property and good operability for an all-cover motorcycle with a narrow body.
Description
The utility model relates to motorcycle gear box, particularly a kind of autoscooter V-type belt wheel toric transmission.
Existing riding-type motorcycle step change transmission, magneto generator and driving gear are installed in crankshaft two end, the power-transfer clutch of power can be cut off or connect to the driving gear transmission, power-transfer clutch is installed in the transmission main shaft end that variable gear is equipped with at the middle part, this structure (one) change-speed box lateral dimension is the thickness sum of crank mechanism, magneto generator, power-transfer clutch, lateral dimension is wide, and (two) can not stepless change.Existing autoscooter V-type belt wheel toric transmission, magneto generator and main pulley are installed in crankshaft two end see figure six, main pulley is by V-type strap drive driven pulley, all be provided with movable inclined-plane on main pulley and the driven pulley, the disk back side, movable inclined-plane of main pulley is furnished with several centrifugal weightss, when engine speed is low more, centrifugal weights is drawn close to the main pulley shaft core direction more, make the effective diameter of V-type band contact main pulley little, the effective diameter big retarding of contact driven pulley is bigger than more, when engine speed is high more, centrifugal weights moves to the main pulley edge direction more, make the effective diameter of V-type band contact main pulley big, the little reduction ratio of effective diameter of contact driven pulley is more little, this structure (one) change-speed box lateral dimension is a crank mechanism, magneto generator, the thickness sum of main pulley, the wide unfavorable one-tenth car of lateral dimension is handsome in appearance, (2) main pulley and driven pulley are arranged on a side of back wheels of vehicle, replace vehicle frame list rear arm damping effect poor with gearbox body, (3) center of gravity of whole driving engine is leaned on after, weight is asymmetric, and manipulative capability is poor.
It is narrow that the purpose of this utility model provides a kind of lateral dimension, and suitable car body is provided with long rear arm, the V-type belt wheel toric transmission of weight symmetry.
The utility model is to realize like this; Driving gear is installed in the bent axle termination, at bent axle and the rectangular car body lengthwise position of car body and the bent axle middle part that be arranged in parallel main pulley is housed, the transmission main shaft of driven gear is installed in the termination, and the driving gear transfer driven gear makes main pulley, the running of V-type band driven pulley, carries out stepless change.
The utility model compared with prior art its remarkable advantage is, (1) it is handsome in appearance to help into car, the narrow vehicle body motor bike of particularly a kind of all cover handsome in appearance, (2) driving engine is loaded on the car body middle part and can makes the rear arm growth, good damping effect, (3) the driving engine center of gravity is provided with rationally, the weight symmetry, and manipulative capability is good.
Accompanying drawing one to figure five has been described the utility model embodiment
Figure one is the utility model gear transmission V-type belt wheel toric transmission structural representation
Figure two above bent axle with the bent axle transmission main shaft side-looking structural representation that be arranged in parallel
Figure three is at the rear of bent axle and the bent axle transmission main shaft side-looking structural representation that be arranged in parallel
Figure four below bent axle with the bent axle transmission main shaft side-looking structural representation that be arranged in parallel
Figure five is that driving gear utilizes intermediate gear indirect drive driven gear side-looking structural representation
Figure six is existing autoscooter V-type belt wheel toric transmission structural representations.
Gear transmission V-type belt wheel toric transmission, mainly form by bent axle (1) main pulley (2) V-type band (3) driven pulley (4) magneto generator (5), it is characterized in that: driving gear (6) is installed in bent axle (1) termination, at bent axle (1) and the rectangular car body lengthwise position of car body and bent axle (1) middle part that be arranged in parallel the transmission main shaft (8) of main pulley (2) termination installation driven gear (7) magneto generator (5) is housed, sees figure one.After engine starting, bent axle (1) rotates under the effect of piston, connecting rod, driving gear (6) transfer driven gear (7) makes main pulley (2) V-type band (3) driven pulley (4) running, along with the variation of engine speed, utilize the folding on the movable inclined-plane of main pulley (2) driven pulley (4) to carry out stepless change.In order to further specify the correlativity of the whole transmission of the utility model, the ratio speed reducer structure is decided in (9) expression in figure one, figure six.The gear transmission V-type belt wheel toric transmission that the utility model proposes, the method of its driving gear (6) transfer driven gear (7) can be that driving gear (6) through-coupling driven gear (7) is seen figure one to figure four, also can be that driving gear (6) utilizes intermediate gear (10) indirect drive driven gear (7) running to see figure five, the number of teeth of its driving gear (6) can be and the number of teeth of driven gear (7) equates, the number of teeth of driving gear (6) also can be the number of teeth that is less than driven gear (7), the number of teeth of driving gear (6) also can be the number of teeth more than driven gear (7), in bent axle (1) and the rectangular car body lengthwise position of car body, can be to see figure two at the top of bent axle (1) and bent axle (1) transmission main shaft (8) that be arranged in parallel, in bent axle (1) and the rectangular car body lengthwise position of car body, also can be to see figure three at the rear of bent axle (1) and bent axle (1) transmission main shaft that be arranged in parallel, in bent axle (1) and the rectangular car body lengthwise position of car body, also can be to see figure four at the below of bent axle (1) and bent axle (1) transmission main shaft (8) that be arranged in parallel, all can obtain same effect, no substantial differences.
