The invention is described below with reference to specific embodiments in conjunction with the accompanying drawings.
A shock absorber assembly 100 in accordance with an embodiment of the present invention will first be described with reference to figures 1-3.
As shown in fig. 1 to 3, a shock absorber assembly 100 according to an embodiment of the present invention may include a dust cover 1 and an oil storage tube 2, the oil storage tube 2 may be at least partially located in the dust cover 1 and spaced apart from the dust cover 1, an inner peripheral wall or an outer peripheral wall of the dust cover 1 may be provided with a first magnet 11, an inner peripheral wall or an outer peripheral wall of the oil storage tube 2 may be provided with a second magnet 21, and when the oil storage tube 2 is located in the dust cover 1, the first magnet 11 may magnetically cooperate with the second magnet 21 to generate a magnetic repulsive force between the first magnet 11 and the second magnet 21, and the magnetic repulsive force may hinder the oil storage tube 2 from moving radially in the dust cover 1, so as to avoid collision between the dust cover 1 and the oil.
In other words, the surfaces of the same magnetic poles of the first magnet 11 and the second magnet 21 can be opposite to each other, so that the first magnet 11 and the second magnet 21 repel each other to separate the oil storage tube 2 from the dust cover 1, and the oil storage tube 2 and the dust cover 1 can be coaxially arranged, thereby ensuring the installation accuracy of the oil storage tube 2 in the dust cover 1 and avoiding the collision caused by the mutual approach of the oil storage tube 2 and the dust cover 1 when the piston rod of the shock absorber assembly 100 moves.
According to the shock absorber assembly 100 provided by the embodiment of the invention, the first magnet 11 and the second magnet 21 are arranged, so that the installation accuracy of the oil storage cylinder 2 in the dust cover 1 can be ensured, the collision between the oil storage cylinder 2 and the dust cover 1 caused by the mutual approach of the oil storage cylinder 2 and the dust cover 1 when the piston rod of the shock absorber assembly 100 moves is avoided, abnormal sound caused by the collision between the oil storage cylinder 2 and the dust cover 1 when the shock absorber assembly 100 works is prevented, the NVH performance of a vehicle is improved, meanwhile, the abrasion caused by the collision between the peripheral wall of the oil storage cylinder 2 and the dust cover 1 is avoided, and the service life of the shock.
In some alternative embodiments of the present invention, as shown in fig. 1 to 3, the first magnet 11 may be provided at the inner wall of the dust cap 1 and the second magnet 21 may be provided at the outer wall of the oil reservoir 2. From this, the distance between first magnet 11 and the second magnet 21 is closer, and first magnet 11 and second magnet 21 are arranged in the space between dust cover 1 and oil storage cylinder 2 simultaneously, guarantee to have stronger repulsion between first magnet 11 and the second magnet 21, better avoid oil storage cylinder 2's perisporium to collide with dust cover 1.
In some specific embodiments, as shown in fig. 1 and 3, the bottom end of the dust cover 1 may be provided with an opening, and the bottom end of the first magnet 11 may extend to the opening. Therefore, the first magnet 11 is fully ensured to be opposite to the second magnet 21 of the oil storage cylinder 2 when the oil storage cylinder 2 moves relative to the dust cover 1 along the axial direction, and the oil storage cylinder 2 is ensured not to collide with the dust cover 1 when moving relative to the dust cover 1 along the axial direction.
Specifically, as shown in fig. 2, the second magnet 21 may be disposed at the top of the reserve tube 2. Because the top of an oil storage section of thick bamboo 2 is at first got into in the dust cover 1, can guarantee from this that an oil storage section of thick bamboo 2 is at first when getting into in the dust cover 1, second magnet 21 can take place magnetism with first magnet 11 and repel each other, can not collide with dust cover 1 when further guaranteeing an oil storage section of thick bamboo 2 motion in dust cover 1.
In some specific embodiments, as shown in fig. 3, the first magnet 11 may be a plurality of elongated magnets parallel to each other, and the plurality of first magnets 11 may be arranged at intervals along the circumferential direction of the dust cover 1. It should be noted that the shape of the first magnet 11 may be different from this, and in other specific embodiments, the first magnet 11 is a ring magnet and is disposed around the peripheral wall of the dust cover 1. From this first magnet 11 can exert magnetic repulsion to oil storage cylinder 2 in circumference, guarantees that all directions of oil storage cylinder 2 perisporium can not take place to collide with dust cover 1 when axial motion.
More specifically, as shown in fig. 3, the length direction of the first magnet 11 may be parallel to the axial direction of the cartridge 2. From this, the length direction of first magnet 11 can be unanimous with the motion direction of the relative dust cover 1 of an oil storage section of thick bamboo 2 to when the relative dust cover 1 axial motion of an oil storage section of thick bamboo 2, first magnet 11 can exert repulsion to second magnet 21 better, avoids an oil storage section of thick bamboo 2 to collide with dust cover 1.
In some more specific embodiments, the oil cartridge 2 may have a top dead center position and a bottom dead center position with respect to the dust cap 1, an upper end surface of the second magnet 21 may not be higher than an upper end surface of the first magnet 11 when the oil cartridge 2 moves to the top dead center position with respect to the dust cap 1, and a lower end surface of the second magnet 21 may not be lower than a lower end surface of the first magnet 11 when the oil cartridge 2 moves to the bottom dead center position with respect to the dust cap 1.
In other words, when the oil storage cylinder 2 moves axially relative to the dust cover 1, the second magnet 21 can be located within the length range of the first magnet 11 all the time, so that the second magnet 21 and the first magnet 11 are ensured to be always opposite to each other when the oil storage cylinder 2 moves axially relative to the dust cover 1, and further, when the oil storage cylinder 2 moves axially relative to the dust cover 1, the oil storage cylinder 2 can be always spaced apart from the dust cover 1 under the magnetic repulsion force between the first magnet 11 and the second magnet 21.
In some embodiments, as shown in fig. 2, the second magnet 21 is a ring magnet and is disposed around the peripheral wall of the oil reservoir 2. It should be noted that the second magnet 21 may be arranged in a different manner and shape, and in other specific embodiments, the second magnet 21 may be a plurality of elongated magnets parallel to each other, and the plurality of elongated second magnets 21 may be spaced apart along the circumferential direction of the oil storage cylinder 2. Therefore, the second magnet 21 can receive the repulsive force of the first magnet 11 in the circumferential direction, and the second magnet can ensure that the second magnet does not collide with the dust cover 1 when the oil storage cylinder 2 moves axially in all directions of the circumferential wall of the oil storage cylinder 2.
