Description

Electric vehicle suspension with buffer block bushing

Technical Field

The utility model relates to the field of vehicle chassis systems, in particular to an electric vehicle suspension with a buffer block bushing.

Background

With the requirement of longer service life of the electric commercial vehicle, the requirement of the service life of the suspension becomes higher. At present, in domestic electric commercial vehicles, front and rear suspensions mainly adopt an assembled structure and a Steyr structure of fuel oil type commercial vehicles, the assembled structure and the Steyr structure are heavy in weight and high in cost, and the damage of large torque to a power assembly when the electric vehicle is started cannot be well improved, and the torsion performance is extremely poor.

Disclosure of Invention

The utility model aims to provide an electric vehicle suspension with a buffer block bush, which has the advantages of light weight, low cost, equipment strength performance meeting the loading requirement and capability of effectively improving the damage of large torque to a power assembly when a motor is started.

In order to achieve the purpose, the technical scheme of the utility model is as follows: the utility model provides a take electric motor car suspension of buffer block bush, includes bush inner frame, bush exoskeleton, outer linking bridge, the bush rubber body and buffering film, bush inner frame, bush exoskeleton and bush rubber body vulcanize together through vulcanization mould and constitute the bush main part, install outer linking bridge at bush main part top, the buffering film has two sets ofly, installs the both sides in the bush main part through interference fit.

Preferably, one end of the outer connecting support is connected with the frame, and the other end of the outer connecting support is connected with the motor support and is installed together through bolts.

Preferably, the lining rubber body is positioned between the lining inner framework and the lining outer framework.

Preferably, the outer connecting bracket is mounted on the outer side of the bushing exoskeleton.

Due to the adoption of the technical scheme, the utility model has the beneficial effects that:

1. the weight of the assembled suspension adopted by the fuel commercial vehicle is about 7.5-10Kg, and the torsional fatigue life is only 100 ten thousand times under the condition of 1G +/-2G;

2. the weight of a Steyr structure suspension adopted by the fuel commercial vehicle is about 3.5-5 Kg; the torsional fatigue life is only 50 ten thousand times under the condition of 1G +/-2G;

3. the suspension weight of the novel electric vehicle with the buffer block device is about 3.5-4 Kg; the torsional fatigue life can meet 200 ten thousand times under the condition of 1G +/-2G.

From the above comparison, the present invention is the same as the steiner structure in weight and cost, but the fatigue life is 4 times that of the steiner structure; compared with the assembled structure, the torsional fatigue life is improved by 2 times, the weight is reduced by more than 4Kg compared with the assembled structure, and the cost is only about 50 percent of the assembled structure.

In summary, the utility model has the advantages of light weight, low cost, equipment strength performance meeting the loading requirement and capability of effectively improving the damage of large torque to the power assembly when the motor is started.
