The clutch-type mechanical stepless variable speed mechanism is characterized in that two transfer half-axles are respectively provided with a variable speed sliding table, two variable speed bolts which are connected with the transfer half-axles in a stationary fit way are respectively arranged in the slots of the sliding tables, and otherwise, each variable speed bolt is sheathed with a sliding block and a compression spring. The sliding tables move by manipulating a rocking handle mechanism, the position height of the sliding blocks is changed by the function of the conical surfaces of the sliding tables, and then the tractive linear speed of the combination of the sliding blocks and chains and the rotational speed of an output shaft are changed to realize stepless variable speed. The utility model has the advantages of convenient operation, strong applicability, small power loss, etc.
Description
The utility model relates to a kind of spliting and joining type mechanical stepless speed change mechanism that is used for automobile and Transport Machinery.
Stepless speed variator system has the gear shift mode that belt driven type, hydraulic driven and machinery combine with hydraulic pressure in the prior art, as hydraulic torque converter and semi-circular toric transmission etc.The belt-driving shortcoming is easy to wear, the life-span is short, can not transfer larger torque, and the shortcoming of other several modes is operating mechanism complexity, and craft precision is had relatively high expectations, and needs configure dedicated hydraulic system transfers power again simultaneously, and the system dynamic loss is bigger, and cost is high.
The purpose of this utility model is at above-mentioned shortcoming, and a kind of simple, later-model spliting and joining type mechanical stepless speed change mechanism is provided.
The purpose of this utility model is to realize like this, this spliting and joining type mechanical stepless speed change mechanism mainly decomposes mechanism by power, power speed changing mechanism, synthetic output mechanism three parts of power are formed, it is characterized in that power input shaft (2) is provided with a pair of half garden stud wheel (3) that certain axial distance is arranged, and is respectively equipped with garden stud wheel (4) on two branch semiaxis (1) parallel with power input shaft (2), slide unit (8) speed change bolt assembly (5), push and block ring assemblies (9), compression spring (10), power take-off shaft (14) is provided with a pair of flywheel (13) that can only unidirectional rotation transfer torque; Its speed change bolt (5) places in the chute of slide unit (8), and is connected with transfer semiaxis (1) close fit; Slide block (7) and compression spring (6) are enclosed within on the speed change bolt (5); Slide unit (8) is the garden cone table, and when slide unit (8) was mobile vertically, slide block (7) upwards or down moved, and changes chain line speed, realizes speed change.Power take-off shaft (14) is provided with a pair of flywheel (13) that can only unidirectional rotation transfer torque, the outer sprocket wheel of flywheel and chain (12) engagement.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is a structural principle scheme drawing of the present utility model.
Among the figure: stud wheel 4-garden, 1-transfer semiaxis 2-power input shaft 3-half garden stud wheel 5-speed change bolt 6-spring 7-slide block 8-slide unit 9-push and block ring 10-compression spring 11-steel rope 12-chain 13-flywheel 14-power take-off shaft 15-fixed pulley 16-rocking handle mechanism 17-double-screw bolt 18-spiral duct 19-push and block ring assemblies 20-tension spring 21-movable pulley
As shown in Figure 1, power input shaft (2) is gone up close fit and one half garden post wheels (3) is housed, and both have certain axial distance on axle (2), and the orientation differs 180 °, does unidirectional rotary motion with power input shaft (2).On two transfer semiaxis (1) parallel garden stud wheel (4) is housed respectively with power take-off shaft (2), respectively with the corresponding engagement of two and half garden stud wheels (3), in addition, be respectively equipped with slide unit (8) on two transfer semiaxis (1), speed change bolt (5) places in the chute of speed change slide unit (8), and have a slide block (7) and compression spring (6) to be enclosed within on the speed change bolt (5), slide block (7) is connected with steel rope (11) and chain combination (12).
Because the chain (12) that two speed change bolts (5) are affected is connected, at one time, left half axle garden stud wheel (4) and cooresponding semi-circle gear (3) engagement, right axle shaft cylindrical wheel (4 ') locates to separate state with cooresponding semicolumn gear (3 '); Left half axle forward load rotates, affect chain (12) to drive right axle shaft and do reverse unloaded the rotation, behind semiaxis (1) Rotate 180 ° then be right axle shaft forward load rotate, left half axle is no-load running, and so forth, power alternately passes to power take-off shaft (14), a pair of can only be unidirectional rotation transmit the interior wheel and output shaft (14) close fit of the flywheel (13) of intertwine square, the outer sprocket wheel of flywheel (13) and chain (12) engagement, chain (12) drives flywheel (13) foreign steamer and forward rotates with interior wheel when forward affecting.Chain (12) is when oppositely affecting, then drive the outer sprocket wheel retrograde rotation of flywheel (13), outer sprocket wheel is then relative with interior wheel to trackslip, simultaneously, interior wheel in another flywheel (13) is then affected by another chain and does forward rotation, so power take-off shaft (14) is under the alternately drive of the interior wheel of two flywheels (13), all the time do unidirectional rotation, the output synthesized-power.
When needing speed change, rely on push and block ring combination (9) to promote speed change slide unit (8), slide unit (8) endwisely slips on semiaxis (1), the component that produces on its conical surface can change the height of speed change bolt (5) top shoe (7), this moment at cireular frequency one regularly, change the linear velocity of the tractive of slide block (7) and chain combination, thereby changed the rotative speed of output (14).
One end of push and block ring combination (9) touches mutually with swivel bolt (17), when slewing maneuver rocking handle (16) forward, bolt (17) translation in spiral duct (18), promote push and block ring combination (9), stage clip (10) is compressed, slide unit (8) is pushed, spring (6) on the speed change bolt (5) is compressed simultaneously, and slide block (7) moves up, during reversible control rocking handle (16), oppositely translation of double-screw bolt (17), two compression springs are upheld, and promote slide unit (8) reverse slide, slide block (7) thus move down the speed that changes output shaft (14), realize speed change, two pitch chain bars (12) are linked to each other by one section steel rope, and to change transmission direction, other is provided with a tension spring (20) pulling movable pulley by 2 fixed pulleys (15), play the tension chain combination, when system quickened, the chain stroke was elongated, caused tension spring to elongate, movable pulley is close to two fixed pulley lines, the deposit length so that chain combination speed change to be provided.
The utlity model has easy and simple to handle, strong adaptability, the advantage such as randomness is good, and power loss is little, and cost is low, and manufacturing process is simple.
