Described slide block (19), it is configured to: on slide block (19), respectively establish one group of adaptive sliding wheels (76) in the both sides of guide groove outside, adaptive sliding wheels (76) are provided with top sheave (80) and lower sheave (81), the assembly pulley beam (78) of fixed block is provided with between two pulleys, the middle part of assembly pulley beam (78) is vertical with the push rod (79) in the push rod guide groove (82) be arranged on slide block (19) to be fixedly connected, in push rod guide groove (82), be provided with holddown spring (77) in the rear end of push rod (79).
Described driving mechanism (25), it is configured to: one end of driving gear shaft (24) connects with driving gear axle (31) keyway, and driven wheel (30) is meshed with the worm screw (29) of motor shaft (28) axle head.
Described driven wheel (30), comprise toothed foreign steamer (1) and interiorly to take turns (2), foreign steamer (1) is enclosed within interiorly takes turns on (2), flexible buffer block (3) is provided with between interior foreign steamer, interior outer rim of taking turns (2) is provided with caster (5) in ellipse, the inner edge of foreign steamer (1) is provided with the interior caster groove (4) adapted with interior caster (5), interior caster (5) and interior caster groove (4) in interlocking shape, the both sides of foreign steamer (1) be provided with fixing in the front stator (6) of foreign steamer and rear stator (7).Interior foreign steamer joint has caster (5) and interior caster groove (4) in one group at least.Flexible buffer block (3) is polyurethane material.
Driving-belt driven gear (15) and driving-belt driving gear (14) are respectively equipped with passive tooth driving-belt gathering sill (55) and driving tooth driving-belt gathering sill (35), to prevent driving-belt slippage.
The invention has the beneficial effects as follows that the contact area of lifter driving-belt and travelling gear is large, stress point disperses, and muting function is good, avoid picture cable pulley type automotive window lifter wire rope and drive contact area little, stress point concentrates the drawback of serious wear; After slide block is worn and torn, holddown spring can head on assembly pulley reach, to compensate the wearing and tearing of slide block, thus makes slide block keep stable, decreases the incidence of lifter in use fault; Driven wheel is buffer gear cold, when can run into obstacle or stop suddenly in window lifting process, makes driven wheel have the process of a soft transitions to impact force, plays a protective role to gear, extend the application life of lifter.
