Embodiment Construction

[0031] The present invention will be further elaborated below in conjunction with the accompanying drawings.

[0032] The damping method that the present invention is applied on electric vehicle adopts is as follows:

[0033] The wheels are connected to the suspension bridge, and the main force spring is used to connect the suspension bridge with the car body to form a non-independent suspension damping system.

[0034] First, design the main force spring according to the sum of mass M of the whole vehicle and the battery, so that the maximum elastic force sum K of all the main force springs meets the following conditions: K / (M*9.8)=1, that is, the maximum elastic force sum K of all the main force springs is equal to that of the entire vehicle Together with the mass sum of the battery M multiplied by 9.8 is equal. Of course, this design is idealized. In order to leave a certain margin, you can make K / (M*9.8)=1.1, preferably not more than 1.2. Because, once the ratio of K / (M...

Abstract

A shock absorbing method and a lever-type non-independent suspension bridge device of an electric automobile belong to the field of automobiles and are characterized by comprising a suspension bridge. Wheels are connected with the suspension bridge, main springs connect the suspension bridge and an automobile body, an auxiliary spring is arranged at a position of the end of the suspension bridge close to the wheels, a shock absorber is arranged in the auxiliary spring, one end of the shock absorber is connected with the suspension bridge, the other end of the shock absorber is connected with the automobile body, and the auxiliary spring is sleeved on the shock absorber. Due to the fact that two main springs are arranged on the suspension bridge with the automobile main body weight, load capacity of the main springs can only match net mass of the automobile, and the auxiliary spring is arranged at the position close to the wheels and only bears the load of staff weight. When the wheelsare lifted to cross obstacles, by means of the lever principle, the compression size of the main springs is greatly reduced, and the shock impact of the spring force on the automobile is greatly reduced. In addition, the suspension bridge is lifted in inclined mode to cause fulcrum changes, force counteracted on tires is greatly reduced, energy for producing bumping is reduced, and a shock absorbing effect is greatly improved.

Description

technical field [0001] The invention belongs to the field of electric vehicles, and in particular relates to a shock absorption method and a suspension bridge device of an electric vehicle. Background technique [0002] With the continuous rise of crude oil prices and the needs of domestic environmental protection, new energy vehicles have become an industry that is supported and developed by the state. Over the years, electric vehicles have gradually been accepted by the people and promoted by the government. The energy source of electric vehicles is batteries, but currently electric vehicles driven by batteries have shortcomings in terms of speed and mileage. The reason is that the contradiction between battery capacity, battery weight and vehicle weight has not been well resolved. If the body weight is too large, starting, climbing and high speed will quickly consume the limited electric capacity. The effective way is to reduce the weight of the car body, so that the st...
