Problems solved by technology
[0004] In order to make up for the deficiencies of the prior art, a semi-trailer suspension device described in the present invention can limit the steel plates in the leaf spring bracket in multiple directions from the up-down direction, the front-rear direction and the left-right direction, thereby solving the problem of semi-trailer suspension. The front and back movement between the middle spring steel plate and the leaf spring bracket causes a large friction problem

The invention relates to the field of semi-trailers, in particular to a novel suspension device of a semi-trailer. The novel suspension device comprises a suspension main body; the suspension main body comprises steel plate springs, semi-trailer axles, U-shaped bolts and pin shafts; the steel plate springs comprise the front spring and the rear spring which are composed of multiple layers of elastic steel plates correspondingly; and a rolling lug serving as a pin shaft hole is arranged at the front end of the rear spring. The novel suspension device further comprises airbags and a lubricating device, and the suspension main body further comprises a steel plate spring bracket. The steel plates in the steel plate spring bracket can be subjected to multiple-direction limiting in the up-down direction, the front-rear direction and the left-right direction, and then the problem that during semi-trailer suspension, the spring steel plates and the steel plate spring bracket move in the front-rear direction, and thus friction is large is solved; the steel plate springs can be well buffered through design of the airbags; and the steel plate springs can be fully lubricated through design of the lubrication device.
Description
technical field [0001] The invention relates to the field of semi-trailers, in particular to a semi-trailer suspension device. Background technique [0002] The semi-trailer suspension device is one of the main components of the semi-trailer. Its main function is to effectively, reasonably and firmly connect the moving parts of the semi-trailer axle with the semi-trailer beam. The suspension device of the road semi-trailer, the suspension bracket is welded to the lower end of the main longitudinal beam of the semi-trailer, the load on the body is transmitted to the leaf spring through the suspension bracket, and then to the axle; the other side of the axle is connected to an adjacent The leaf spring bracket is connected to bear the lateral force. For a semi-trailer using this suspension method, when some wheels touch the ground and some wheels are suspended, all the loads of the semi-trailer will be borne by the wheels that touch the ground. Axle overload, on the other han...
