Problems solved by technology

[0002] At present, in the hydraulic suspension of four-wheeled vehicles, the hydraulic cylinders of each wheel are independent. When the vehicle is running on an uneven road, the body and frame will be subjected to a large torsional load, and at the same time, the load on each wheel will be different. Evenly distributed, thus reducing the adhesion and passability between the wheels and the ground, and the asymmetric disturbance of the ground to the vehicle will also aggravate the vibration of the vehicle when driving on uneven roads, reducing the ride comfort of the vehicle

Embodiment Construction

[0011] The structure of the present invention will be further described in detail below with reference to the embodiments given in the accompanying drawings.

[0012] Referring to Figure 1, a hydraulic vehicle torsion-eliminating suspension device is formed by closing and communicating hydraulic cylinders respectively arranged on each wheel suspension with a four-chamber hydraulic balancer composed of pistons and cylinders through pipelines, namely :Left front, right rear, left rear, right front suspension hydraulic cylinders 8, 11, 10, 9 are connected to the four chambers 4, 5, 6, 7 of the four-chamber hydraulic balancer; one of the four-chamber hydraulic balancer The four chambers follow the following hydraulic correlation structure distribution: when the piston moves to the right, chambers 4 and 5 are decompressed at the same time, and chambers 6 and 7 are pressurized at the same time; when the piston is moved to the left, chambers 6 and 7 are decompressed at the same time , Ch...

Abstract

The invention refers to a kind of hydraulic pin hanger bracket device which can eliminate car torsion carrier. It is made up by connecting the hydraulic cylinder set on each car hanger bracket and four-cylinder hydraulic balancer made up by piston and cylinder through pipes, namely: left anterior, right posterolateral, left posterior and right anterior hanger bracket cylinders are connected to the four cavities of the four-cylinder hydraulic balancer respectively; the four cavities of the four-cylinder hydraulic balancer accords to following hydraulic association structure distribution: when the piston moves to the right, the cavities is decompressed, the other two cavities are boosted; when the piston is moved to the left, the former two cavities are decompressed at the same time, the other two cavities are boosted. The device can maintain the four wheels charge even, it improves the smooth performance and passing performance.

Description

Technical field [0001] The invention relates to a suspension device of a wheeled vehicle, in particular to a torsion-eliminating suspension device that can eliminate the torsional load of the vehicle body. Background technique [0002] At present, in the hydraulic suspension of a four-wheeled vehicle, the hydraulic cylinders of each wheel are independent. When the vehicle is running on uneven roads, the body and frame will be subjected to a large torsional load, and at the same time, the load of each wheel will be different. Evenly distributed, thus reducing the adhesion and passability between the wheels and the ground, and the asymmetric disturbance of the ground to the vehicle will also aggravate the vibration of the vehicle when driving on uneven roads and reduce the smoothness of the vehicle. Summary of the invention [0003] The purpose of the present invention is to provide a new type of hydraulic vehicle torsion-eliminating suspension device, which can effectively elimin...
