Problems solved by technology

The elastic elements of the existing special vehicle chassis suspension system are arranged on the upper cross arm. This arrangement makes the height of the frame section higher, so that the center of mass of the whole vehicle is higher, which reduces the driving safety and handling stability of the vehicle. Most of the upper and lower cross arms of the existing special vehicle chassis suspension system are connected to the steering knuckle through a rigid connection, the layout space is not compact enough, the structure is complicated, and it is not easy to achieve a large wheel runout and wheel angle

Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] Such as figure 1 , figure 2 As shown, the low-height independent suspension of the special vehicle chassis of the present invention can connect two or more independent suspension subunits in series through pipelines according to the number of vehicle axles and the use requirements;

[0027] Each independent suspension sub-unit includes upper cross arm 1, lower cross arm 2, ball joint 3, oil-pneumatic spring A4, upper cross-arm pin 5, lower cross-arm pin 6, oil-pneumatic spring upper pin 7, oil-pneumatic spring lower pin 8. Limiting block 10, steering knuckle 12; one end of the upper lug of the oil-gas spring A4 is connected to the frame 11 through the upper pin 7 of the oil-gas spring, and one end of the lower lug of the oil-gas spring A4 is connected to the lower crossbar through the lower pin 8 of the oil-gas spring. The arm 2 is ...

Abstract

The invention belongs to the technical field of specific vehicle chassis, and particularly relates to a low independent suspension of a specific vehicle chassis. The suspension is formed by connecting two or more sets of independent suspension subunits in series through pipelines. Each independent suspension subunit comprises an upper cross arm, a lower cross arm, a hydro-pneumatic spring A, a limiting block and a steering knuckle, wherein one end of an upper supporting lug of the hydro-pneumatic spring A is connected with a frame, one end of a lower supporting lug of the hydro-pneumatic spring A is connected with the lower cross arm, the upper cross arm is connected with the frame and the steering knuckle, the lower cross arm is connected with the frame and the steering knuckle, and the limiting block is connected with the frame and located above the upper cross arm. By the adoption of the low independent suspension of the special vehicle chassis, the requirements of a new generation cross-country military vehicle for high maneuverability and high cross-country ability can be met, and handling stability and driving safety of the vehicle are improved.

Description

technical field [0001] The invention belongs to the technical field of special vehicle chassis, and in particular relates to a low-height independent suspension of a special vehicle chassis. Background technique [0002] With the continuous improvement of the maximum speed and acceleration performance of the new generation of tactical off-road military vehicles, the vehicle chassis is required to have higher driving safety and handling, so higher requirements are put forward for the design of the vehicle chassis. The elastic elements of the existing special vehicle chassis suspension system are arranged on the upper cross arm. This arrangement makes the height of the frame section higher, so that the center of mass of the whole vehicle is higher, which reduces the driving safety and handling stability of the vehicle. Most of the upper and lower cross arms of the existing special vehicle chassis suspension system are connected with the steering knuckle through a rigid connect...
