What are the components of the independent suspension

Lower arm assembly of independent suspension of heavy vehicle, It is characterized by including a pivot (1) and a swing arm (2). The swing arm (2) is fork-shaped, and the tail end of the swing arm (2) is provided with a connecting hole connected to the axle wheel side, the swing arm ( 2) A coil spring mounting hole is provided in the middle, and the two prongs at the fork end of the swing arm (2) are rotatably connected to both ends of the pivot (1). The lower swing arm assembly of the heavy vehicle independent suspension is characterized in that the pivot (1) and the fork arm (2) are connected in such a way that the two fork blades are provided with pivot mounting holes on the same axis, A pivot bushing (3) is provided in the pivot mounting hole, both ends of the pivot shaft (1) are rotatably provided in the pivot bushing (3), and an end cover is provided at the outer end of the pivot mounting hole ( 7), an oil seal (11) is provided on the inner end portion of the pivot mounting hole, and a curved neck grease nipple (10) is provided on the end cover (7). The lower swing arm assembly of the heavy vehicle independent suspension includes a pivot and a swing arm. The swing arm is fork-shaped, and the tail end of the swing arm is provided with a connecting hole to connect with the axle wheel side, and the middle of the swing arm is provided with a spiral The spring installation hole, the two prongs at the fork end of the swing arm are rotatably connected with the two ends of the pivot. Due to the adoption of the lower arm assembly of the utility model, when the car is driving on an uneven road, the wheels on both sides can move independently without affecting each other, which can reduce the vibration of the frame and ensure that the car runs on an uneven road At this time, all wheels have good contact with the road, thereby increasing traction and increasing the passing performance of the car. In the 120 years that motor vehicles have existed, great development has taken place in motor vehicle suspension systems. This development is mainly motivated by the following factors to stimulate the evolving understanding of the impact of the suspension on the behavior of the vehicle, and thus the characteristics required of the suspension in order to ensure that the vehicle has favorable driving characteristics. Automobile independent suspension can be more than McPherson independent suspension In modern vehicles, a suspension system can be described as a system of components that connect a wheel frame (including wheels) to a vehicle structure. The suspension system of modern vehicles is usually a linkage system consisting of rigid load-bearing links that can articulate around joints (usually in the form of rubber bushings). Suspension configurations can be classified into such configurations. Their complexity is different, and therefore, their cost and performance are different. Examples of common suspension constructions are McPherson strut suspension, double wishbone independent suspension, live axle suspension and torsion beam axle suspension. According to the degree of interconnection of the suspension structure between the left and right hand wheels of the axle, the suspension structure can be further divided into three main categories, which are independent suspension, semi-independent suspension, and non-independent suspension. In the independent suspension system, there is no connection between the left and right hand wheels (except for the attached anti-sway bar, which is usually ignored under these definitions), and thus has no effect on each other's movements. The independent suspension system is generally applied to the front and / or rear of high-end vehicles and / or high-performance vehicles. In a non-independent suspension system, the left and right hand wheel brackets are rigidly connected to each other. Non-independent suspension systems are usually applied to the front and / or rear of heavy commercial vehicles. In the semi-independent suspension system, the left and right hand wheel brackets are not rigidly connected. The connection between the left and right hand wheels allows for sufficient rigidity to allow the movement of one wheel to significantly affect the movement of the opposite wheel. Such suspension systems may contain so-called torsion beam axle suspensions, and are the most common construction in this category. Semi-independent suspension systems, especially torsion beam axle suspensions, are typically applied to the rear of small and medium-sized vehicles due to cost considerations. At the same time, front systems typically include independent suspension systems, such as the aforementioned wheat Fulson pillar suspension.
