High comfort performance independent suspension for new energy bus

Abstract

The invention discloses a high comfort performance independent suspension for a new energy bus. The high comfort performance independent suspension for the new energy bus comprises a steering knuckleassembly, a mounting plate, a brake disc, a hub assembly and a control arm, wherein the mounting plate, the brake disc and the hub assembly are fixed on the end surface of the steering knuckle assembly; the control arm is connected with the steering knuckle assembly; connecting lug blocks are arranged at the upper and lower ends of the steering knuckle assembly; the control arm is connected with the connecting lug block through a short pin rotating piece in a rotating manner; a step-shaped mounting hole is formed in the connecting lug block; a U-shaped fork is arranged at the end part of the control arm; coaxial mounting holes are formed in the two sides of the U-shaped fork; the short pin rotating piece comprises a short pin connecting piece and a T-shaped knuckle, wherein one end of theshort pin connecting piece is connected with the mounting hole through a bearing, and the two ends of the T-shaped knuckle are erected in the coaxial mounting holes through bearings; and the other endof the short pin connecting piece is fixedly connected with the T-shaped knuckle. According to the high comfort performance independent suspension for the new energy bus, the kingpin offset distanceis reduced, the kingpin inclination angle is increased, and the stability and comfort of the braking of the complete bus are improved.

Description

【Technical field】 [0001] The invention relates to a suspension structure, in particular to an independent suspension with high comfort for a new energy bus. 【Background technique】 [0002] Car suspension is an important part to ensure ride comfort. At the same time, the suspension of a bus, as a force transmission device connecting the frame (or body) and the axle (or wheel), is also an important part to ensure the safety of the bus, and it is one of the indicators to measure the comfort of the bus. Due to the fact that there are few independent suspension manufacturers before research and development for 7-9m buses, there are few suitable tonnage front independent suspension varieties available for selection, which cannot form a wide industrial effect and limit the promotion of corresponding independent suspensions. At present, the domestic small tonnage front independent suspension is mainly based on the solid kingpin structure. Due to the influence of the steering knuckl...

Problems solved by technology

After the gap is generated, the front wheel alignment parameters will change in real time, which will cause the body to bump and wear tires

Due to the limitation of the T-shaped joint structure and the structure of the solid kingpin, the distance from the center of the brake disc to the mounting surface of the wheel hub is large, and the distance between the center of the brake disc and the force center of the tire is large, which increases the braking deflection moment generated by vehicle braking, and is not It is conducive to the stability of the vehicle when braking, and at the same time increases the load on the hub bearing, which is not conducive to the life of the hub bearing
