Embodiment Construction

[0019] like figure 1 As shown, it is a structural schematic diagram of a double-track rope-wheel type car window shaker that can be used for the front window of a car. Driven by the drive motor 7, the steel wire rope 8 goes around the first pulley 1, the second pulley 2, the third pulley 3 and the fourth pulley. The pulley 4 drives the first slider 5 to move between the first top dead center 11 and the first bottom dead center 12, and the second slider 6 moves between the second top dead center 13 and the second bottom dead center 14. The resulting cambered surface of the guide rail forms the first bonding point 15 and the second bonding point 16 of the steel wire rope 8 and the guide rail. combine figure 2 , 3 And 4, the double-track rope wheel type automobile window shaker of the present invention, the angle α of the supporting assembly surface of the guide rail pulley of the window shaker and the wire rope outlet direction F is given by the formula:

Abstract

The invention relates to a rope wheel type automobile window lifter. An angle Alpha between a supporting assembly surface of a guide rail pulley of the widow lifter and a steel wire rope outgoing direction is determined by a formula, wherein T represents the circulation times of upward sliding and downward sliding of the window lifter, s1 represents the stroke of a sliding block when the sliding block slides to a position where the steel wire rope is attached to the guide rail from an upper stop point, s2 represents the stroke of the sliding block when the sliding block slides to a lower stop point from the position where the steel wire rope is attached to the guide rail, F.sina Alpha represents the axial pressure of the steel wire rope to the pulley, n represents the corresponding unit abrasion loss, and m represents the corresponding abrasion loss when the window lifter loses effectiveness; when the sliding block is at the upper end of the guide rail, an included angle between a connecting wire led from the steel wire rope to the sliding block and the supporting assembly surface of the pulley is Alpha 1; and during the sliding block slides to the bottom of the guide rail from the upper part to the lower part, as the working surface of the guide rail is arc-shaped, the steel wire rope can be attached to the upper surface of the guide rail, and an included angle between a connecting line led from the steel wire rope to the attaching point and the supporting assembly surface of the pulley is Alpha 2.

Description

technical field [0001] The invention belongs to the technical field of auto parts, in particular to a sheave-type automobile window shaker. Background technique [0002] For the rope pulley window shaker, the pulley is an important part of the operation of the whole mechanism. With the development of technology, the weight of the rope wheel car window shaker itself has been greatly reduced, which also makes the operation of the window shaker more stable. However, in the long-term use process, it can be found that many wire ropes in the aftermarket have come out of the guide rail pulley. This is because the four (or two) pulleys in the transmission cannot be kept parallel to the lead-out angle of the wire rope at the same time, and the wire rope will wear between the pulleys during the movement, which makes the probability of the wire rope jumping out of the pulley also low. Then it rises, and the jumping out of the wire rope will directly lead to the failure of the entire ...
