Cavel structure for front auxiliary frame and front auxiliary frame

Abstract

The cleat structure is arranged on the left side and the right side of the middle of the front auxiliary frame and comprises cleat supports arranged on the tops of corresponding longitudinal beams of the front auxiliary frame up and down, and the lower ends of the cleat supports wrap the top faces of the corresponding longitudinal beams and are fixed to the top faces of swing arm supports on the outer sides of the longitudinal beams. The upper end of the cleat support is provided with a connecting hole channel which vertically extends and allows a connecting bolt connected with a vehicle body to penetrate through, the outer side of the hole wall of the connecting hole channel is broken in the height direction and exposed, the lower end opening of the connecting hole channel is in a closed state, and the upper end opening of the connecting hole channel is exposed out of the top face of the cleat support and is in an open state. And the connecting bolt is communicated with the crevasse of the connecting hole channel to form a separation notch for separating the connecting bolt when the vehicle collides. According to the front auxiliary frame, the connecting bolt can be easily separated from the cleat support when a vehicle is collided, the situation that the front auxiliary frame moves backwards and is embedded into a passenger compartment is avoided, and the life safety of a driver and passengers is protected.

Description

technical field [0001] The invention relates to the field of automobile chassis components, in particular to a horn structure used for a front auxiliary frame and the front auxiliary frame. Background technique [0002] The front sub-frame is the skeleton of the front and rear axles and an important part of the car chassis. Its main function is to reduce the impact of road vibration on the car body, improve the connection stiffness of the suspension system, and improve the comfort and stability of the car during driving. In addition, the sub-frame can also reduce the noise caused by the engine and road vibration, and improve the quiet level of the car cabin. [0003] Furthermore, the front sub-frame and the body are connected by a six-point structure, and the middle mounting point between the sub-frame and the body adopts a croissant structure. For example, the patent number is ZL 201921833169.X (authorized announcement number is CN211494231U) of the Chinese utility model p...

AI Technical Summary

Problems solved by technology

[0004] The existing horn structures are all closed, so that when the vehicle collides, the connecting bolts between the horn structure and the vehicle body are not easy to fall off, and the mounting structure between the front sub-frame and the body becomes detached and fails, and the energy generated by the car collision passes through the front sub-vehicle The frame is transmitted to the passenger compartment, which poses a danger to the life safety of the passengers
