Abstract

The invention discloses a drive axle balance suspension and a car crane. The drive axle balance suspension comprises two groups of balance units, and a balance support which is arranged between the two groups of balance units and hinged with a car frame; each group of balance units comprises a balance rod, a swinging arm and a plate spring; one end of the balance rod is hinged with the balance support, the other end of the balance rod is hinged with a first end of the swinging arm, a second end of the swinging arm is hinged with the car frame, the plate spring is arranged on a car axle, one end of the plate spring is lapped on a third end of the swinging arm, and the other end of the plate spring is lapped on the balance support; and the balance rod, the swinging arm and the plate spring in each group of balance units form a four-bar mechanism with the balance support. The two balance units in the drive axle balance suspension rotate around the car frame by virtue of the balance support; and when the car axle with a relatively large designed shaft load runs on a fluctuated pavement, the vertical load is identical under any situation, so that the entire car is stable to run.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a drive axle balance suspension and a truck crane. Background technique [0002] Suspension is the general term for all balance connection devices between the car frame (or load-bearing body) and the axle (also called axle). The two ends of the axle are equipped with car wheels, and the function of the suspension is to transmit the action on the wheels. The force and torque between the vehicle and the frame, and buffer the impact force transmitted from the uneven road to the frame or body, and reduce the vibration caused by it, so as to ensure that the car can run smoothly. [0003] Now heavy-duty truck cranes are driven by double rear axles. In order to improve driving comfort, a balanced suspension structure is required for shock absorption. [0004] like figure 1 As shown, the balance suspension in the existing truck crane includes: middle bridge 3, rear axle 6, first leaf ...
