Problems solved by technology

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 hand, will reduce the traction of multi-axle drive vehicles, which will easily cause damage to wheels, axles and leaf springs due to exceeding their strength limit
[0003] At the same time, when the vehicle is running, each steel plate of the leaf spring of the suspension device of the semi-trailer will move up and down, resulting in friction, and this friction will interact with each other, so that the spring steel plate is easily damaged, thus giving the driver's Great danger to personal safety

Abstract

The invention relates to the field of semitrailers, in particular to a high wear-resistant suspension gear for the semitrailer. The high wear-resistant suspension gear comprises a suspension main body, a protection main body and a cooling main body, the suspension main body comprises a suspension bracket, an axle, a steel plate spring bracket, a steel plate spring, a U-shaped bolt, a support seat, a pin shaft and a balance shaft, the cooling main body comprises a nozzle, a cooling main pipe and a cooling thin pipe, and the protection main body comprises a wear-resistant antiskid rubber sleeve I, a wear-resistant antiskid rubber sleeve II and a wear-resistant antiskid rubber mat. The high wear-resistant suspension gear solves the problem that part of a wheel is suspended on a bumpy road, the wear of the suspension gear is slowed down, and the service life of the suspension gear is prolonged.

Description

technical field [0001] The invention relates to the field of semi-trailers, in particular to a high wear-resistant suspension device for a semi-trailer. 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 ...
