Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of automobile parts, especially to a high shock absorption type four-wheel drive auxiliary frame. BACKGROUND
[0002] The auxiliary frame can be regarded as the framework of the front and rear axles and is a component part of the front and rear axles. The auxiliary frame is not a complete frame but a support for the front and rear axles and suspension, so that the axles and suspension are connected to the "main frame" through the auxiliary frame. The auxiliary frame is usually called "auxiliary frame". The function of the auxiliary frame is to block vibration and noise and reduce the direct entry of the vibration and noise into the vehicle cabin, so the auxiliary frame is mostly used in luxury cars and off-road vehicles. Some cars also have auxiliary frames for engines. The suspension of the traditional load-bearing body without an auxiliary frame is directly connected to the body steel plate. Therefore, the suspension rocker mechanisms of the front and rear axles are not assemblies but separate parts. After the auxiliary frame is born, the front and rear suspensions can be assembled on the auxiliary frame to form an axle assembly, which is then installed on the vehicle body as a whole.
[0003] However, the existing auxiliary frame of the vehicle is a hollow structure, and lacks a support structure inside. In the event of a vehicle collision, the overall frame of the auxiliary frame is prone to deformation or even breakage, which not only increases the maintenance cost of the vehicle but also affects the safety of the passengers in the vehicle.
