Description

Technical Field

[0001] The utility model relates to a single-point suspension, in particular to a single-point suspension for reducing the height of a traction rod, and belongs to the technical field of single-point suspension. Background Art

[0002] Suspension is the general term for all force-transmitting connection devices between the frame (or load-bearing body) and the axle (or wheel) of a car. Its function is to transmit the force and torque acting between the wheel and the frame, and to cushion the impact force transmitted to the frame or body by the uneven road surface, and reduce the vibration caused thereby, so as to ensure that the car can run smoothly. There are many types of suspensions, among which single-point suspension is widely used in semi-trailers and other transport vehicles as a relatively mature technology. In order to better avoid the unstable center of gravity of the vehicle when loaded, more people now choose to use single-point suspension with a lowered drawbar height.

[0003] Among them, the application number is "CN201820388311.3", which is a single-point suspension for reducing the height of the tow bar. It includes a single-point suspension with a support frame, and a hollow sleeve is fixedly provided on the upper surface of the support frame in the movement direction of the single-point suspension. The sleeve is partially or completely sunken and pre-buried in the support frame. The sleeve is provided with a plurality of connecting holes that are perpendicular to the sleeve and penetrate the side wall at the position where the sleeve extends relative to the support frame. The tow bar passes through the inside of the sleeve, and the tow bar is connected to the sleeve by a towing pin passing through the connecting hole and the towing hole. The beneficial effect is that by utilizing the sleeve that can be sunk into the single-point suspension support frame, the vehicle installed on the single-point suspension can obtain a smaller height from the ground, and by utilizing the particularity of the waist-shaped hole structure, the single-point suspension fully loaded with wood can self-adjust the swing angle according to the road surface, thereby obtaining a greater grip effect.

[0004] However, the above-mentioned method still has certain shortcomings when used. It can only match vehicles within a certain range of center of gravity requirements, and cannot match the different center of gravity requirements of different vehicles or carriages with different cargo capacities, and is not convenient for better adjusting the height of the tow bar.
